The Clavien-Dindo classification of surgical complications: five-year experience

Laparoscopic versus open distal gastrectomy with d2 lymphadenectomy in treatment of locally T4A gastric cancer: the protocol of a randomized controlled trial

BACKGROUND

Gastric cancer (GC) remains one of the leading causes of cancer-related mortality worldwide. While laparoscopic gastrectomy (LG) has been widely adopted for early and locally advanced gastric cancer (AGC), its safety and oncological efficacy in T4a GC remain unclear. To date, no randomized controlled trials have specifically examined the role of LG in the treatment of T4a GC. This study aims to provide robust evidence comparing the short- and long-term outcomes of laparoscopic distal gastrectomy (LDG) versus open distal gastrectomy (ODG) in resectable T4a GC.

METHODS

This is a phase III, randomized controlled, non-inferiority trial. Patients with clinical T4a GC (cT4aN0-3M0) suitable for distal gastrectomy with D2 dissection will be randomly assigned in a 1:1 ratio to undergo either LDG or ODG. A total 240 patients (120 each group) are required to statistically show non-inferiority of the LDG with respect to the primary end-point, 3-years disease-free survival (DFS). Secondary endpoints include morbiity, mortality, postoperative recovery, and quality of life.

DISCUSSION

This study is the first prospective randomized trial specifically designed to compare laparoscopic and open approaches for T4a GC. By standardizing surgical techniques and ensuring experienced surgeons perform the procedures, this trial aims to establish whether LDG can provide equivalent oncological outcomes while reducing perioperative morbidity and enhancing postoperative recovery. The findings will provide high-quality evidence to inform future guidelines and clinical decision-making in the management of T4a gastric cancer.

TRIAL REGISTRATION

This study is registered at ClinicalTrials.gov (NCT04384757), version 6. Registration Date: 08/05/2020.

Postoperative complications following salvage neck dissection after (chemo)radiotherapy for head and neck squamous cell carcinoma: which patients are at high risk?

BACKGROUND

Salvage neck dissection (ND) is the treatment of choice for residual neck disease after (chemo)radiotherapy for head-and-neck squamous cell carcinoma (HNSCC). Although ND is a relatively safe surgical procedure, several studies have shown that salvage ND will increase the morbidity of (chemo)radiotherapy with possible increase in acute and late toxicity and deterioration of quality-of-life. Therefore, unnecessary salvage ND need to be avoided. However, the available literature could not identify potential groups at higher risk of post-operative complications because of the missing demographic information and the heterogeneity in studies and outcome data. We aim to report on the types, rates, and severity of postoperative complications and to identify groups of patients at high risk of these complications.

METHODS

Of 908 patients with node-positive HNSCC primarily treated with (chemo)radiotherapy between 2008 and 2022, 130 (14%) underwent salvage ND. Endpoints of the study are the incidence of G ≥ 2 and G3 postoperative complications, identification of risk factors for these complications and the oncologic outcomes.

RESULTS

Of all patients who underwent salvage ND, 41% still had vital tumor in ND-specimen (pN +). No G4-5 complications were reported. The incidence of G3 and G ≥ 2(CTCAE.v5) postoperative complications were 18% and 52%, respectively. Events reported as G3 complications were wound infection/dehiscence (n = 9), fistula (n = 4), bleeding (n = 4), tracheotomy (n = 6), dysphagia (n = 4), severe pneumonia and septicemia (n = 2), and frozen shoulder (n = 1). Seven patients had more than one type of G3 complications. Logistic regression showed that extent of salvage ND, size of the largest node and HPV-negative disease were independent predictors for G ≥ 2 complications. Multivariable analysis showed that G ≥ 2 complications was not associated with worse OS while HPV-negative and N3-disease were independent predictors for worse survival.

CONCLUSIONS

Of all patients who underwent salvage ND, 41% still had residual neck disease while 52% developed G ≥ 2 and 18% G3 complications. Although OS was not worse in these patients, accurate detection of residual neck disease is essential to spare considerable number of patients from unnecessary salvage ND with its possible complications. Patients with lymph nodes larger than 3 cm, HPV-negative disease and those treated by (modified)radical ND were at high risk of G ≥ 2 complications.

Comparison of clinical and cost outcomes between primary and interval debulking surgery in ovarian cancer

INTRODUCTION

While neoadjuvant chemotherapy with interval debulking surgery (IDS) has comparable clinical outcomes to primary debulking surgery (PDS) for advanced epithelial ovarian cancer, their economic dimension remains understudied.

METHODS

This retrospective chart review examined Stage IIIC-IV epithelial ovarian cancer patients who underwent IDS or PDS between 2011 and 2014. We compared the demographics, disease-specific, intraoperative, thirty-day clinical outcome and billing, and ten-year survival data.

RESULTS

Patients who underwent PDS (n = 36) and IDS (n = 43) had similar characteristics, including age, comorbidity, cancer stage, cell type, nationality, and 30-day median bill sizes (SGD 31,649.69 vs. SGD 35,326.02). The IDS group had lower postoperative sepsis (2.3% vs. 16.7%), gastrointestinal complications (0.0% vs. 11.1%) and suboptimal debulking (14.0% vs. 33.3%) rates, shorter median hospital stay (5 vs. 8 days) and higher rates of complete gross resection (CGR) (62.8% vs. 36.1%) (all P < 0.05). There were significant associations between thirty-day complications and mucinous adenocarcinomas (odds ratio [OR] 10.8), packed cell transfusion (OR 1.87 per unit), and suboptimal debulking (OR 6.33). Thirty-day readmission or death was significantly associated with Clavien-Dindo Grade I-II complications (OR 46.8) and suboptimal debulking (OR 8.24). While PDS and IDS groups had similar ten-year survival (37.0% vs. 16.2%), PDS conferred a significantly lower recurrence rate (66.7% vs. 83.7%, P = 0.003).

CONCLUSION

The thirty-day cost and ten-year survival of IDS and PDS are comparable. Although IDS offers lower postoperative sepsis and gastrointestinal complications, shorter hospital stays and higher CGR rates, the ten-year recurrence is higher.

Integrating Machine Learning and Dynamic Digital Follow-up for Enhanced Prediction of Postoperative Complications in Bariatric Surgery

BACKGROUND

Traditional risk models, such as POSSUM and OS-MS, have limited accuracy in predicting complications after bariatric surgery. Machine learning (ML) offers new opportunities for personalized risk assessment by incorporating artificial intelligence (AI). This study aimed to develop and evaluate two ML-based models: one using preoperative clinical data and another integrating postoperative data from a mobile application.

METHODS

A prospective study was conducted on 104 bariatric surgery patients at Saint-Pierre University Hospital (September 2022-July 2023). Patients used the "Care4Today" mobile app for real-time postoperative monitoring. Data were analyzed using ML algorithms, with performance evaluated via cross-validation, accuracy, F1 scores, and AUC. A preoperative model used demographic and surgical data, while a postoperative model incorporated symptoms and mobile app-generated alerts.

RESULTS

A total of 104 patients were included. The preoperative model, utilizing Extreme linear discriminant analysis, achieved an accuracy of 75% and an AUC of 64.7%. The postoperative model, using supervised logistic regression with six selected features, demonstrated improved performance with an accuracy of 77.4% and an AUC of 71.5%. A user interface was developed for clinical implementation.

CONCLUSIONS

ML-based predictive models, particularly those integrating dynamic postoperative data, improve risk stratification in bariatric surgery. Real-time mobile health monitoring enhances early complication detection, offering a personalized, adaptable approach beyond traditional static risk models. Future validation with larger datasets is necessary to confirm generalizability.

Comparative analysis of oncological and surgical outcomes of robotic versus conventional mastectomy for breast cancer

OBJECTIVE

This study aimed to compare the surgical and oncological outcomes of robotic mastectomy (RM) and conventional mastectomy (CM) for breast cancer.

METHODS

Our institutional registry of women with breast cancer who received RM between 2018 and 2023 and CM between 2016 and 2023 were reviewed. Propensity score matching of clinicopathological variables was used to match 123 RM patients with 123 CM patients. Surgical outcomes, reconstruction type, margin status, complications, recurrence-free survival (RFS), and overall survival (OS) were compared between the 2 groups. Complications with increasing RM experience were also examined.

RESULTS

More autologous flap reconstructions were used in RM (67 % vs. 39 %, p < 0.001), but more implant reconstructions were used in CM (61 % vs. 33 %, p < 0.001). The complication rate, especially breast skin necrosis, was lower in the RM group (10 % vs. 26 %, p = 0.002). Nipple-areolar complex necrosis in nipple-sparing mastectomy was similar between the groups (33 % vs. 27 %, p = 0.45). At a median follow-up of 30 months, RFS was comparable between the 2 groups, as was OS (median follow-up 36 months). More RM experience was associated with shorter operation time and lower surgical complication and margin positive rates.

CONCLUSION

The oncological outcomes of RM and CM are similar at a follow-up of about 3 years. RM is associated with a significantly lower rate of breast skin necrosis, and the advantage of RM exists with different types of breast reconstruction. Increasing RM experience leads to improved overall results.

Long-term outcomes of hepatopancreatoduodenectomy for perihilar cholangiocarcinoma: A comparative study with conventional hepatectomy

INTRODUCTION

Hepatopancreatoduodenectomy (HPD) is necessary to achieve a reliable margin-negative resection for widespread perihilar cholangiocarcinoma (PhCC), yet data on long-term outcomes following HPD for PhCC remain limited.

MATERIALS AND METHODS

A retrospective cohort study was conducted on 167 patients with PhCC who underwent surgery with curative-intent between 2000 and 2023. Hepatic resection and extrahepatic bile duct resection (Hr-BDR) were performed for cases presumed to have localized tumors, while HPD was conducted for cases with presumed extensive tumor spread. Short- and long-term outcomes, including surgery details, pathological findings, postoperative complications, survival rates, and recurrence patterns, were compared.

RESULTS

Forty-five patients underwent HPD and 122 underwent Hr-BDR. No differences were observed in the T or N factors of the TNM staging between both groups (P = 0.09 and 0.09). Overall postoperative significant complications (38 % vs. 34 %, P = 0.62), 90-day mortality rates (2 % vs. 2 %, P = 0.80), and 5-year cancer-specific survival (45 % vs. 40 %, P = 0.81) were comparable between both groups. However, the 5-year survival rate of the HPD group was significantly higher than that of the Hr-BDR group with positive invasive duodenal-side ductal margins (45 % vs. 0 %, P = 0.03). Local and remnant bile duct recurrence were significantly less frequent in the HPD than in the Hr-BDR group (20 % vs. 37 %, P = 0.04; 11 % vs. 0 %, P = 0.02, respectively).

CONCLUSION

Although HPD for widespread PhCC requires careful postoperative management, it has the potential to provide excellent long-term outcomes, and it should be considered proactively.

Appetite-preserving gastrectomy (APG) for esophagogastric junction cancer: preserving the residual stomach as an endocrine organ

BACKGROUND

Loss of appetite following gastric cancer surgery, particularly total gastrectomy, significantly impacts patient quality of life due to the removal of the ghrelin-secreting region. We developed appetite-preserving gastrectomy (APG), a modified total gastrectomy that preserves this region.

METHODS

Ten consecutive patients with esophagogastric junction cancer who were indicated for total gastrectomy and underwent APG between April 2023 and April 2024 were evaluated for early surgical outcomes, appetite, and changes in weight and body composition.

RESULTS

There were no postoperative complications of grade II or higher (Clavien-Dindo classification). Appetite, assessed using the Simplified Nutritional Appetite Questionnaire, showed no significant impairment at 3 months (14.5 points, P = 0.82) and 6 months (15 points, P = 0.44) postoperatively compared with preoperative values. Oral calorie intake was maintained at 3 months (1675 kcal, P = 0.97) and 6 months (1675 kcal, P = 0.22) postoperatively compared with preoperative levels. The patients' body weight decreased by 9.2% at 6 months postoperatively compared with preoperative values, but their lean body mass remained stable. Although a significant decrease in the blood Ghrelin levels was observed postoperatively, 53% and 60.4% of the preoperative levels was maintained at one month and 6 months, respectively.

CONCLUSIONS

APG is a safe procedure that preserves the residual stomach as an endocrine organ, maintains ghrelin secretion and appetite, and prevents muscle loss. However, further trials are required to compare the efficacy of APG with total gastrectomy in preventing postoperative appetite loss.

Trifecta of Same-Day Discharge after Single-Port Robotic-Assisted Simple Prostatectomy

Introduction: There are numerous options available for the surgical treatment of benign prostate hyperplasia, and single-port robotic-assisted simple prostatectomy (SP-RASP) has emerged as a novel method in this field. In this study, we aim to define the trifecta of same-day discharge (SDD) and identify the factors associated with the trifecta of SDD following SP-RASP. Materials and Methods: Data from 95 patients who underwent SP-RASP between February 2020 and July 2024 at a single center by a single surgeon were evaluated. The trifecta of SDD was defined as a patient being discharged on the same day without experiencing any 90-day postoperative complications and no readmissions. The factors associated with predicting the trifecta of SDD were investigated. Results: A total of 95 SP-RASP cases were successfully performed without the need for conversion to alternative approaches, and 54 patients (56.8%) were included in the trifecta of the SDD-achieved group. The reasons for failure included 23 patients (24.2%) requiring postoperative hospitalization from the recovery area, 24 patients (25.3%) experiencing postoperative complications, and 2 patients (2.1%) needing readmission within 90 days after discharge. There was a 0% incidence of major postoperative complications (≥Clavien-Dindo grade 3). When comparing the groups, trifecta-achieved patients showed lower estimated blood loss, smaller specimen weight, lower percentage of adenoma removed, and a reduced rate of opioid prescriptions at discharge (p = 0.005, 0.033, 0.025, and 0.026, respectively). In the multivariate logistic regression analysis, specimen weight was the only factor significantly associated with trifecta following SP-RASP (p = 0.018). Conclusion: In our cohort, 56% of patients were classified within the trifecta group, with no major postoperative complications observed following SP-RASP. Specimen weight was the only independent predictor of trifecta achievement in these patients.

Sclerosing Encapsulating Peritonitis: A Surgical Challenge in Liver Transplantation

Sclerosing Encapsulating Peritonitis (SEP) is a rare condition characterized by chronic inflammation of the peritoneum, of either idiopathic origin or sometimes due to local or systemic factors. The symptoms are often non-specific, and in many cases, the diagnosis is only made during laparotomy or laparoscopy. In severe cases, SEP can be a contraindication for liver transplantation because of the associated risk of surgical complications.

METHOD

To report on the incidence and management of SEP identified during liver transplantation at our center, and to document the associated Serious Adverse Events (SAEs).

RESULTS

We present a series of 3 cases from 2022 to 2023, where SEP was diagnosed intraoperatively. These cases were marked by significant technical challenges, including extensive adhesions, dense fibrous encapsulations, and severe intraoperative hemorrhage necessitating blood transfusions. Despite these complexities, all transplants were successfully completed. One patient experienced a peak serum AST of 2000 U/L, and another had a bilirubin of 10 mg/dL, indicative of early graft dysfunction, both of which resolved within the first week. One patient required an emergency laparotomy due to hemorrhage. No additional severe complications were observed postoperatively. All patients are currently alive with functioning grafts and have been followed for at least 18 months.

CONCLUSIONS

A multidisciplinary approach and advanced surgical planning are crucial for successfully performing complex liver transplants in patients with SEP. Intraoperative recognition of SEP requires meticulous strategies to minimize blood loss and optimize hemostasis, while avoiding organ injuries, as these factors are critical for improving the survival outcomes in these patients.

Short-and middle-term outcomes of robot-assisted minimally invasive esophagectomy for highly locally advanced esophageal cancer with stage cT3 borderline and cT4b at initial diagnosis

BACKGROUND

Although the efficacy of robot-assisted minimally invasive esophagectomy (RAMIE) in locally advanced esophageal cancer has been suggested, solid evidence is lacking. In this study, we examined the short- and middle-term outcomes of RAMIE in patients with highly locally advanced esophageal cancer who were initially diagnosed with cT3 borderline resectable or cT4b (cT3br/cT4b) disease and deemed resectable after preoperative treatment. Furthermore, we compared the short- and middle-term outcomes of RAMIE with conventional minimally invasive esophagectomy (cMIE).

METHODS

Eighty-one patients with locally advanced initial T3br and T4 esophageal squamous cell carcinoma previously treated with chemotherapy or chemoradiation underwent minimally invasive esophagectomy with curative intent between 2018 and 2022. We then examined the short- and long-term outcomes of RAMIE compared with cMIE in patients initially diagnosed with stage cT3br/cT4b disease.

RESULTS

Among these 81 patients, 33 underwent RAMIE and 48 underwent cMIE. The average age of the 81 patients was 65.8 years, with tumors located primarily in the mid-esophagus (55.6%). Most patients initially had stage cT3br (56.8%) or cT4b (43.2%) disease, with 88.9% showing invasion near the trachea or bronchus. No significant differences were observed between the cMIE and RAMIE groups for operation time, blood loss, or common postoperative complications. However, the RAMIE group had a lower incomplete resection rate vs the cMIE group (9.0% vs 16.6%, respectively). The 3-year overall survival rate was 63.1%, with RAMIE showing slightly better survival rates compared with cMIE (p = 0.032). The prognostic factors in the RAMIE group indicated better outcomes for single-organ vs multiple-organ invasion (p = 0.036) and patients with a higher histological response (p = 0.048).

CONCLUSION

RAMIE may offer improved outcomes for highly locally advanced esophageal cancer, such as patients with stage T3br or T4b disease. Future studies that analyze data for high numbers of cases in multiple facilities are needed.

Outcomes and Complications After Elective Thoracic and Lumbar Spinal Fusion in Elderly Patients: A Comparison of Methods to Predict Adverse Events

Study DesignRetrospective study.ObjectivesThe current study compares the ability of the modified Frailty Index (mFI), the American Society of Anesthesiologists (ASA) classification, the modified Charleston Comorbidity Index (mCCI), the American College of Surgeons Surgical Risk Calculator (SRC), and the Fusion Risk Score (FRS) to predict perioperative outcomes.MethodsComorbidity indices were calculated for patients undergoing elective thoracic and lumbar spinal fusion at a single institution and assessed for their discriminative ability in predicting the desired outcomes using an area under the curve (AUC) analysis.Results393 patients met the inclusion and exclusion criteria. Patients being treated for adult spinal deformity (ASD) had the highest rate of complications (44.4%). The FRS had acceptable discrimination (AUC >0.7) and the highest ability among the methods studied to predict any adverse effects, new neurological deficit, return to OR within 90 days, and surgical site infection. It had good discrimination ability (AUC >0.8) predicting durotomy, respiratory failure (RF) requiring intubation, hemodynamic instability, and sepsis. The SRC had acceptable discrimination and highest ability to predict deep venous thrombosis (DVT). The mCCI had excellent and the highest ability to predict acute renal failure (ARF). For the other outcomes, the indices had either poor predictive ability (AUC 0.6-0.7) or no discriminative ability (AUC <0.6).ConclusionsThe FRS had a better ability than the ASA, mCCI, mFI, and SRC to predict the most perioperative adverse events and reoperation. Further study is needed to develop preoperative indices with better predictive ability of postoperative outcomes.

Comparison between minimally invasive surgery and open surgery in managing localized adrenocortical carcinoma treatment: A retrospective propensity-matched study

BACKGROUND

It was controversial to use open surgery or minimally invasive surgery (MIS) for adrenocortical carcinoma (ACC). This retrospective study aimed to evaluate the impact on prognosis between MIS and open surgery in patients with clinical stage I-II ACC.

METHODS

Patients with stage I-II ACC from December 2000 to October 2022 were retrospectively studied. The primary endpoint was recurrence-free survival time calculated by the Kaplan-Meier curves.

RESULTS

In total, 95 patients were enrolled in this study (50 open surgery and 45 MIS). Propensity score matching identified 32 matched pairs of patients. Compared with the open surgery group, the MIS group had a shorter median operative time (150.0 vs. 120.0 min, p = 0.014), the lesser median volume of intraoperative blood loss (200.0 vs. 60.0 mL, p = 0.006), lower incidence of postoperative complications (59.4% vs. 28.1%, p = 0.023), and shorter median postoperative length of hospital stay (8.0 vs. 7.0 days, p = 0.001). After a median follow-up time of 20.5 months, no significant differences were observed in the local recurrence rate (62.5% vs. 78.1%), distant metastasis rate (15.6% vs. 6.3%), and median time to recurrence (15.0 vs. 20.0 months) between the two groups. The median recurrence-free survival time between the open surgery and MIS groups did not significantly differ (16.0 vs. 21.0 months).

CONCLUSION

MIS might be a feasible option for treating localized ACC at a high patient's volume center with experienced surgeons.

Dynamic sentinel node biopsy in penile cancer: 25 years of experience at a tertiary oncological center

INTRODUCTION

Penile cancer lymph node (LN) metastases are critical prognostic factors. The European Association of Urology (EAU) guidelines recommend dynamic sentinel node biopsy (DSNB) as a less invasive alternative for cN0 patients with intermediate- to high-risk tumors. Due to the rarity of penile cancer, lymph node staging tends to be underutilized, and few centers have a significant number of patients to develop the DSNB technique and observe its evolution over time. Previously, our series reported a sensitivity of 66%, and our aim is to contribute to the available evidence, based on 25 years of real-world experience.

MATERIALS AND METHODS

Retrospective single-center study involving 95 groins of 51 patients with intermediate or high-risk penile squamous carcinoma, who underwent DSNB between November 1999 and July 2024. Clinical data, including histology, surgical treatment, and complications, were analyzed. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. Complications were registered using the Clavien-Dindo system.

RESULTS

The median age of patients was 60 (range 30-84) years. 10/51 patients (21%) had metastatic sentinel node. DSNB successfully identified sentinel nodes in 95.7% for right and 89.5% for left groins. The false-negative rate was 8.1%, with a sensitivity of 77%, specificity of 100%, PPV of 100%, and NPV of 92%. 18% (9/51) of patients suffered complications being most of them minor (6/9), 3 patients experimented major complications.

DISCUSSION AND CONCLUSION

The updated DSNB outcomes show improved diagnostic accuracy compared to previous reports, reflecting enhanced techniques and learning curves. The study highlights the accuracy and the low morbidity of DSNB.

Differential impact of frailty on surgical and non-surgical site complications in patients with gastric cancer undergoing gastrectomy

BACKGROUND

The aim of this study was to determine the differential impact of frailty on surgical site complications (SSCs) and non-surgical site complications (non-SSCs) in gastric cancer (GC) patients undergoing gastrectomy.

METHODS

In this study, frailty was assessed preoperatively using a frailty index (FI) in 395 patients scheduled for gastrectomy for GC between January 2016 and December 2023. Patients were divided into two groups (high FI vs. low FI) to examine the impact of frailty on SSC and non-SSC.

RESULTS

Overall complication and non-SSC rates were significantly higher in the high FI group, but the two groups had similar rates of SSC. In multivariate analysis, high FI, high BMI, and male were independent risk factors for non-SSC. The incidence of non-SSC was 0% in patients with no applicable risk factors, 3.6% in patients with one applicable risk factor, 13.0% in patients with two applicable risk factors, and 37.1% in patients with all three risk factors (Cochran-Armitage trend test, p < 0.001). The area under the curve (AUC) of the risk prediction model using these three variables to predict non-SSC was 0.760.

CONCLUSIONS

High FI was an independent risk factor for non-SSC in patients undergoing gastrectomy for GC. Our developed non-SSC risk model combining FI, BMI, and sex effectively identifies individuals at increased risk for non-SSC in GC patients.

Long-term diuretic medication is an independent predictor of posthepatectomy liver failure

BACKGROUND

Posthepatectomy liver failure (PHLF) is the most fatal complication after liver resection, particularly in patients with comorbidities. This study aimed to assess the effect of long-term medication on PHLF incidence after open liver resections.

METHODS

A retrospective analysis of 682 patients who underwent elective open hepatectomies between 2008 and 2015 at 2 academic centers was performed. Preoperative, intraoperative, and postoperative data were collected, including long-term medication. The risk factors for the development of PHLF and other postoperative complications were evaluated using univariate and multivariate logistic regression analyses.

RESULTS

PHLF occurred in 81 patients (11.9%), with a higher incidence in patients taking diuretics as long-term medication than in those not taking diuretics (17.7% vs 5.3%, respectively; P <.001). Diuretic use was identified as a strong independent risk factor for PHLF (odds ratio [OR], 3.8 [95% CI, 2.1-7.0]; P <.001), alongside liver cirrhosis (OR, 3.8 [95% CI, 1.9-7.6]; P <.001), primary liver malignancies (OR, 3.8 [95% CI, 1.6-9.3]; P <.001), major hepatectomies (OR, 3.1 [95% CI, 1.7-5.7]; P <.001), and long operating time (OR, 4.2 [95% CI, 2.4-7.2]; P <.001). Patients with long-term diuretic intake were older, had higher body mass indices, and had more comorbidities, including liver cirrhosis.

CONCLUSION

Long-term diuretic use is associated with a significantly increased risk of PHLF after open hepatectomy.

Simultaneous versus delayed resection of synchronous colorectal liver metastases: A systematic review and meta-analysis

Colorectal cancer is a leading malignancy, with synchronous colorectal liver metastases (CRLM) presenting in 20 % of patients. Resection remains the gold standard treatment for CRLMs, significantly improving survival outcomes. However, the optimal timing of resection of these synchronous lesions - simultaneous versus staged - remains controversial. This systematic review and meta-analysis synthesises data exclusively from propensity-score-matched and prospective studies. A comprehensive search of five databases identified 11 eligible studies, encompassing 2884 patients. Of these, 1453 underwent simultaneous resection, and 1431 underwent staged procedures. The primary outcome was 5-year overall survival (OS), with secondary outcomes including disease-free survival (DFS), surgical morbidity, operating time, and length of hospital stay. Meta-analysis demonstrated no significant difference in 5-year OS between simultaneous and staged resection groups (odds ratio [OR] 1.10, 95 % CI 0.75-1.61; p = 0.83). However, simultaneous resection was associated with significantly higher 3-year DFS (OR 1.67, 95 % CI 1.28-2.17; p = 0.0001) but also increased major surgical complications (Clavien-Dindo ≥ III: OR 1.32, 95 % CI 1.03-1.68; p = 0.03). This review highlights a lack of oncological advantage for simultaneous resection, coupled with higher morbidity, suggesting its use should be limited to select patients with low surgical risk. The findings underscore the need for well-powered, randomised trials to confirm these conclusions, as well as assess quality of life and economic outcomes, however delivering such trials in this patient cohort brings unique challenges. Until such data are available, clinical decision-making should remain individualised, guided by multidisciplinary discussion and available local expertise.

Eighteen-year analysis of anaesthetic management in Brugada syndrome: The BRUGANAES study

BACKGROUND

Brugada syndrome (BrS) is a genetic disorder that increases the risk of ventricular tachyarrhythmias and sudden cardiac death (SCD). Certain drugs (propofol, local anaesthetics), fever, bradycardia, increased vagal tone and electrolyte imbalances can trigger or worsen BrS arrhythmias.

OBJECTIVE

To evaluate the incidence of malignant ventricular arrhythmias during the perioperative period in patients with BrS, hypothesising that common anaesthetic drugs may be safe to use during daily clinical practice.

DESIGN

The BRUGANAES study was an observational, retrospective project including BrS patients who underwent various types of anaesthesia.

SETTING

BrS patients undergoing any type of anaesthesia intervention from 1 January 2006, to 31 December 2023, from a tertiary hospital in Barcelona.

MAIN OUTCOME MEASURES

The primary outcome was the occurrence of malignant ventricular arrhythmias and/or SCD during and up to 30 days postanaesthesia. Secondary outcomes included adverse events during hospitalisation, 30-day readmission rates and 30-day mortality rates.

RESULTS

Among 652 BrS patients registered in the hospital, 111 patients and 189 procedures were analysed. General anaesthesia was administered in 51.3% of cases, sedation in 36% and regional/neuraxial anaesthesia exclusively in 12.7%. Overall, nonrecommended drugs (propofol, ketamine and local anaesthetics) were used in 129 (68.3%) procedures, either bolus and/or continuous infusion. Epidural blocks were performed in 34% of regional anaesthesia cases, mostly in obstetrics, and subarachnoid blocks in 31.8%. The primary outcome occurred in two patients intraoperatively (1% of procedures): one with bradycardia-induced ventricular fibrillation after a nonrecommended drug and one with transient ventricular tachycardia after a drug not listed as potentially harmful.

CONCLUSION

To date, this is one of the largest cohorts describing the perioperative approach for BrS patients, including a wide range of anaesthesia procedures and drugs. Most of the patients undergoing anaesthesia for an interventional procedure received an anaesthetic drug classified as not recommended.

An effective surgical approach to treat obese patients with gynecological disease using a subcutaneous abdominal wall-retraction device to perform low-pressure laparoscopy: A prospective, single-center study

OBJECTIVE

Laparoscopic surgery of obese patients still represents a real challenge in clinical practice. High-pressure pneumoperitoneum and steep Trendelenburg position are the main anesthesiologic indications to laparotomic conversion. The aim of this prospective study was to assess effectiveness and safety of low-pressure laparoscopic (LPL) procedures using a subcutaneous abdominal wall-retraction (LaparoTenser ®).

MATERIALS AND METHODS

We enrolled obese patients (BMI ≥ 30 kg/m2) with early-stage endometrial cancer, atypical endometrial hyperplasia and suspicious adnexal mass who were planned for laparoscopic surgery.

RESULTS

A total of 33 patients were included in this study. The median age was 69 (range: 40-83), with a median BMI of 39 kg/m2 (range: 33-48). At final pathologic report, 24 patients had endometrial cancer, 4 atypical endometrial hyperplasia, 2 had ovarian borderline tumors and 3 benign cysts. All LPL procedures were performed using the LaparoTenser ® device. Total hysterectomy plus bilateral salpingo-oophorectomy and sentinel node biopsy was the main procedure (69.7 % of cases). Laparotomy conversion rate due to inadequate visualization of the surgical field was 6.1 %. Postoperatively, no patient reported relevant abdominal discomfort caused by lifting of the abdominal wall. Grade < 2 early complications rate was 21.1 %. One grade ≥ 3 complications was reported.

CONCLUSIONS

LPL technique using the LaparoTenser ® device is feasible and safe in morbidly obese patients. The wall-lifting device enables adequate viscera exposure creating a large intra-abdominal operative space avoiding the disadvantages of intraperitoneal high-pressure and CO2 absorption.

The Ratio of Visceral to Subcutaneous Adipose Tissue Is Associated With Postoperative Anastomotic Leakage in Patients With Rectal Cancer With Gender Differences in Opposite Direction

BACKGROUND

Anastomotic leakage (AL) is a severe postoperative complication in colorectal cancer and exerts negative impacts on patients' outcomes. Studies have found that body composition measured by CT images was associated with increased overall postoperative complications in colorectal cancer; however, few focused on postoperative AL in rectal cancer. This study aimed to explore the association between body composition parameters measured by CT images and postoperative AL in patients with rectal cancer, with an emphasis on subgroup analysis by gender.

METHODS

From February 2014 to January 2020, a total of 444 patients with rectal adenocarcinoma who underwent radical proctectomy were included. Out of all patients, 21 developed AL after surgery. Body composition parameters, including the areas, mean CT values, height-normalized indices of subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), intramuscular adipose tissue (IMAT) and skeletal muscle (SM) were derived from preoperative contrast-enhanced arterial phase CT images at the third lumbar level. The ratio of visceral to subcutaneous adipose tissue (VSR) was calculated. Clinical and body composition parameters were compared between the AL group and the non-AL group in all patients and separately in different genders.

RESULTS

Body composition parameters were not significantly different in the AL group and the non-AL group in all patients. However, most body composition parameters were significantly different between male and female patients. After separately analyzing by gender, VSR was significantly associated with postoperative AL in male and female. After multivariate regression, VSR remained an independent predictor for AL (OR: 0.1, p = 0.041 for male and OR: 39.1, p = 0.045 for female).

CONCLUSION

The VSR measured by CT images is an independent predictor for postoperative AL in patients with rectal cancer; however, it shows gender differences in opposite directions, serving as a protective factor in males, whereas as a risk factor in females.

Re-do laparoscopic common bile duct exploration for recurrent common bile duct stones: a single-center retrospective cohort study

Purpose

Common bile duct (CBD) stone recurrence after laparoscopic CBD exploration (LCBDE) is relatively common. No studies have been conducted evaluating the safety and feasibility of re-do LCBDE in the treatment of recurrent CBD stones.

Methods

This single-center retrospective study reviewed 340 consecutive patients who underwent LCBDE for CBD stones between January 2004 and December 2020. Patients with pancreatobiliary malignancies and those who underwent other surgical procedures were excluded.

Results

Of the 340 included patients, 45 experienced a recurrence after a mean follow-up period of 24.2 months. Of them, 18 underwent re-do LCBDE, 20 underwent endoscopic intervention, 2 underwent radiologic intervention, and 5 underwent observation. Re-do LCBDE and initial LCBDE showed similar surgical outcomes in terms of operative time (113.1 minutes vs. 107.5 minutes, P = 0.515), estimated blood loss (42.5 mL vs. 49.1 mL, P = 0.661), open conversion rate (2.9% vs. 0%, P = 0.461), postoperative complication (15.3% vs. 22.2%, P = 0.430), and postoperative hospital stay (6.5 days vs. 6.4 days, P = 0.921). Comparing re-do LCBDE and nonsurgical treatment (endoscopic or radiologic), no statistically significant differences were noted in posttreatment complication (22.2% vs. 13.6%, P = 0.477), hospital stay (6.4 days vs.7.3 days, P = 0.607), and recurrence (50.0% vs. 36.4%, P = 0.385). The clearance rate was higher in the re-do LCBDE group than in the nonsurgical group (100% vs. 81.8%, P = 0.057).

Conclusion

Compared to initial LCBDE and endoscopic or radiological treatments, re-do LCBDE for recurrent CBD stones is a treatment option worth considering in selected patients.

Efficacy and safety of preoperative biliary drainage in patients with Hilar Cholangiocarcinoma: a systematic review and meta-analysis

BACKGROUND

Preoperative biliary drainage (PBD) has been proposed as a strategy to manage the complications associated with biliary obstruction in hilar cholangiocarcinoma patients. However, the efficacy and safety of PBD in remain controversial, even in clinical guidelines. This meta-analysis aimed to provide a comprehensive evaluation of the efficacy and safety of PBD in patients with hilar cholangiocarcinoma.

METHODS

PubMed, Medline, EMBASE, Cochrane Library, and registers were screened to investigate the efficacy and safety of PBD in patients with hilar cholangiocarcinoma. The search timeframe was set before December 2024. Mortality, morbidity, and postoperative infection served as the primary outcomes, while the secondary outcomes included transfusion, operative time, operative bloody loss, intraabdominal abscess, intraabdominal bleeding, leakage (bile leak or anastomotic leakage), hepatic insufficiency, renal insufficiency, second laparotomy, total hospital stay, cholangitis. Studies were evaluated for quality by Newcastle-Ottawa scale. Data were pooled as odds ratio ( OR ) or standard mean difference ( SMD ).

RESULTS

Our meta-analysis of 21 studies (3059 patients) showed that PBD reduced hepatic insufficiency ( OR  = 0.38, 95% CI  = 0.16-0.90, P  = 0.03, I 2  = 69%) but increased risks of long term follow up mortality ( OR  = 1.90, 95% CI  = 1.02-3.56, P  = 0.04, I 2  = 0%), morbidity ( OR  = 1.47, 95% CI  = 1.12-1.92, P  = 0.01, I 2  = 52%), postoperative infection ( OR  = 2.46, 95% CI  = 1.17-5.18, P  = 0.02, I 2  = 69%), transfusion ( OR  = 1.39, 95% CI  = 1.06-1.81, P  = 0.02, I 2  = 49%), leakage ( OR  = 1.67, 95% CI  = 1.08-2.60, P  = 0.02, I 2  = 44%), cholangitis ( OR  = 6.40, 95% CI  = 1.75-23.48, P  = 0.01, I 2  = 51%), and prolonged hospital stay ( SMD  = 0.53, 95% CI  = 0.06-0.99, P  = 0.03, I 2  = 87%). There was no difference in overall mortality, operative time, blood loss, or other complications ( P > 0.05). Subgroup analysis showed that differences in some outcomes lost significance with higher bilirubin levels, fewer PBD cases, studies published after 2010, and strictly select PBD patients ( P < 0.05).

CONCLUSIONS

Routine PBD cannot be recommended but it tends to be a better choice in patients with average initial bilirubin above 218.75 μmol/L, portal vein embolization and malnutrition. Further multicenter randomized studies should address the potential advantages of PBD over NPBD, identify clear patient selection criteria, and determine the optimal bilirubin threshold for PBD.

Analysis of protocol adherence and outcomes of an enhanced recovery program in colorectal surgery after 5 years of implementation

INTRODUCTION

Enhanced recovery program (ERAS program) have revolutionized the world of surgery by reducing postoperative complications and hospital stays. Greater adherence to the protocol results in better outcomes; however, adherence often declines over time. The main objective of this study is to analyze the adherence rate to ERAS strategies and the outcomes of an ERAS colorectal (CRC) program five years after its implementation.

METHODOLOGY

This is a descriptive observational study comparing two groups of patients undergoing scheduled CRC surgery under an ERAS program at University Hospital. The first group (ERAS) includes patients operated on during the period immediately following the implementation of the protocol (January 2017-June 2018), while the second group (ERAS 5) includes patients operated on five years after the implementation (January 2022-June 2022).

RESULTS

An increase in the adherence rate to ERAS strategies was observed (88.2% in ERAS vs. 84.2% in ERAS 5, p 0.003), as well as a reduction in healthcare-associated infections (HAIs) (9% in ERAS vs. 25.2% in ERAS 5, p 0.001) and surgical site infections (6% in ERAS vs. 18.2% in ERAS 5, p 0.002). No differences were found in other postoperative complications, functional recovery, average length of stay, and readmission rates.

CONCLUSIONS

After five years of implementing an ERAS protocol for CRC in our hospital, we have managed to maintain a high adherence rate to ERAS strategies. There has been a significant reduction in HAIs and surgical site infections.

Fit4Surgery app: Home-based prehabilitation app for older patients undergoing elective colorectal cancer surgery

BACKGROUND

Supervised multimodal prehabilitation prior to colorectal cancer (CRC) surgery is associated with reduced complications and enhanced recovery. However, it is labor intensive and expensive. In an aging population with increasing demand and costs on healthcare and staff shortages, home-based prehabilitation (HBP) with an app could be of interest. This study assessed the effectiveness of a Fit4Surgery app in CRC surgery.

METHOD

The app was effectuated in a prospective cohort study of 100 CRC patients ≥60 years from October 2021-December 2022. The primary outcome was preservation or improvement of the 6-minute walking test (6MWT) six weeks postoperative, compared to baseline. Secondary outcomes were 90-day complication and mortality rate, 90-day readmission, length of stay, 6MWT and Short Performance Physical Battery (SPPB) at different timepoints and total costs.

RESULTS

Three patients needed urgent surgery, remaining 97 patients (mean age 72) using the app for at least three weeks. The 6MWT was preserved in 74.7 % with a 12.1 m higher mean six weeks postoperative, compared to baseline (p = 0.194). A significant higher 6MWT was observed after prehabilitation and one year postoperative, compared to baseline (p=<0.001). The SPPB was significant higher at all timepoints. Overall 90-day complication rate was 25.8 %, readmission rate 6.3 % and mortality occurred in 2.1 %. Total costs were €518.50 per patient.

CONCLUSION

This is the first study of multimodal HBP by an app for CRC surgery patients with high compliance. Results show promising results regarding functional capacity and a low occurrence of complications, in line with multimodal supervised prehabilitation. This by reducing costs by half.

Whole-gland or Subtotal High-intensity Focused Ultrasound Versus Radical Prostatectomy: The Prospective, Noninferiority, Nonrandomized HIFI Trial

BACKGROUND AND OBJECTIVE

High-intensity focused ultrasound (HIFU) has emerged as an interesting ablative alternative to radical prostatectomy (RP) and radiation therapy (RT) for localized prostate cancer (PC). However, no prospective comparative data have been published for HIFU.

METHODS

We performed a prospective nonrandomized nationwide trial in 46 centers in France comparing RP versus HIFU. The main inclusion criterion was low- to intermediate-risk PC. The primary endpoint was salvage therapy-free survival (STFS). Secondary endpoints were metastasis-free survival, PC-specific survival, overall survival, and functional outcomes.

KEY FINDINGS AND LIMITATIONS

From 2015 to 2019, 3328 patients were included (1967 HIFU and 1361 RP). Median age was 74.7 versus 65.1 yr (p < 0.001) and median PSA was 7.1 versus 6.9 ng/ml (p = 0.5) in the HIFU and RP groups, respectively. Intermediate-risk PC was diagnosed in 61% of patients in the HIFU group and 64% in the RP group (p = 0.10). The 30-mo STFS was not inferior in the HIFU group (hazard ratio 0.71, 95% confidence interval 0.52-0.97; p = 0.008). Some 10% of patients experienced urinary retention after HIFU. Grade >IIIa complications occurred in 54/1967 cases in the HIFU group and 29/1361 cases in the RP group (p = 0.3). In the HIFU group, fewer patients experienced a deterioration in 12-mo urinary continence (29% vs 44%) and the decrease in median International Index of Erectile Function-5 score was lower (difference -7 vs -13) in comparison to RP. Internal Prostate Symptom Scores and quality-of-life scores were comparable in the two groups. The main limitations are the lack of randomization and the age difference between the groups.

CONCLUSIONS AND CLINICAL IMPLICATIONS

This large prospective trial demonstrates that whole-gland or subtotal HIFU provides comparable medium-term STFS outcomes to RP. Urinary continence and erectile function were less impaired after HIFU. These results should be interpreted with caution owing to the lack of randomization and the age difference between the groups. Future research should consider longer follow-up and evaluate focal treatments. This trial is registered on ClinicalTrials.gov as NCT04307056.

Neoadjuvant Chemoradiotherapy Using Moderately Hypofractionated Intensity-Modulated Radiotherapy Versus Upfront Surgery for Resectable Pancreatic Cancer: A Retrospective Cohort Study

BACKGROUND

The efficacy of neoadjuvant chemoradiotherapy for resectable pancreatic ductal adenocarcinoma (R-PDAC) remains unclear. This study was designed to evaluate neoadjuvant chemoradiotherapy by using intensity-modulated radiotherapy (NAC-IMRT) for R-PDAC compared with upfront surgery (UpS).

METHODS

Among 198 patients with R-PDAC who were indicated for resection between 2013 and 2021, 130 were included in this study after excluding patients who underwent neoadjuvant chemotherapy and did not meet the NAC-IMRT criteria (Eligible set). NAC-IMRT was planned for 58 patients, and UpS was planned for 72 patients. Additionally, in 105 patients who could undergo the planned treatment (As-treated set), the surgical, pathological, and oncological outcomes were evaluated.

RESULTS

In the Eligible set, median overall survival (OS) was 50.5 months with NAC-IMRT and 34.7 months with UpS and progression-free survival was 20.4 months with NAC-IMRT and 13.9 months with UpS. In the As-treated set, OS was longer in the NAC-IMRT group (66.7 months vs. 34.7 months, p = 0.007). On multivariate analysis, NAC-IMRT was identified as an independent factor for better OS (hazard ratio 0.617, 95% confidence interval 0.382-0.995, p = 0.047, in the Eligible set). The incidence of postoperative complications did not show a difference between the two groups, and NAC-IMRT suppressed local tumor invasion, including lymphatic, venous, perineural invasion, and lymph node metastases.

CONCLUSIONS

NAC-IMRT may offer superior survival outcomes and manageable toxicity in R-PDAC patients compared with upfront surgery. This study supports the efficacy and safety of NAC-IMRT and recommends its consideration in R-PDAC treatment protocols.

Indocyanine green fluorescence imaging (ICG-FI) in difficult laparoscopic hepatectomy for hepatocellular carcinoma: a retrospective propensity score-matched analysis

BACKGROUND

Indocyanine green fluorescence imaging (ICG-FI) is increasingly used in laparoscopic hepatectomy (LH). However, its efficacy in enhancing both short- and long-term outcomes in difficult LH for hepatocellular carcinoma (HCC) compared with traditional white light (WL) LH remains unclear.

METHODS

This retrospective cohort study analyzed 573 patients who underwent LH between April 2018 and April 2023, stratified by the use of ICG-FI or WL. Propensity score matching (PSM, 1:1) was employed to minimize baseline discrepancies and reduce selection bias. Perioperative outcomes, overall survival (OS), and recurrence-free survival (RFS) were evaluated. Kaplan-Meier survival analysis was conducted to compare OS and RFS between groups, and Cox regression models were applied to identify independent prognostic factors.

RESULTS

Among the 573 patients who underwent LH, 178 were classified as high-difficulty hepatectomies, including 47 patients in the ICG-FI group and 131 in the WL group. After PSM, 78 patients were matched, with 39 patients in each group. In both unmatched and matched cohorts, the ICG-FI group demonstrated significantly lower conversion rates (2.6% vs. 15.4%, P = 0.048), shorter durations of drainage tube placement (7.0 [5.0, 8.0] vs. 7.0 [6.0, 9.5], P = 0.048), fewer severe postoperative complications (2.6% vs. 15.4%, P = 0.048), and reduced postoperative hospital stays (7 [4.5, 9] vs. 8 [7, 10], P = 0.045). Kaplan-Meier analysis revealed significantly improved RFS in the ICG-FI group compared with the WL group (P = 0.021). Independent predictors of RFS included ICG-FI, liver cirrhosis, and the presence of satellite nodules. Independent predictors of OS included LH performed at the expert difficulty level (HR = 2.875, 95% CI: 1.331-6.207, P = 0.007) and R0 resection (HR = 0.142, 95% CI: 0.028-0.734, P = 0.020).

CONCLUSIONS

ICG-FI demonstrates significant benefits in short-term outcomes and enhances RFS in patients undergoing difficult LH for HCC. However, its impact on OS warrants further validation through large-scale, multicenter prospective studies.

Novel bioabsorbable, low-dose rate brachytherapy device (CivaSheet®) with radical prostatectomy and adjuvant external beam radiation for the management of prostate cancer

OBJECTIVE

To investigate the safety and cancer control of a novel bioabsorbable, low-dose rate brachytherapy device, CivaSheet® (CivaTech Oncology Inc., Durham, NC, USA), in combination with radical prostatectomy (RP) with or without adjuvant external beam radiation therapy (EBRT) for the management of prostate cancer (PCa).

PATIENTS AND METHODS

This is an initial, single-centre experience, two-dose level, two-stage study conducted on patients with intermediate- and high-risk PCa. The CivaSheet was implanted during RP, followed by adjuvant EBRT in patients with adverse pathological features. Toxicities and peri- and postoperative complications were assessed. Biochemical recurrence (BCR) at the 6-month follow-up after EBRT was also evaluated.

RESULTS

Six patients were enrolled, with a median (range) age of 56 (53-71) years. No intraoperative complications occurred. No dose-limiting toxicities were observed at a maximum tested dose of 75 Gy. BCR occurred in one patient at 6 months, while another patient had residual disease and metastasis at 6 months. All patients reported having postoperative erectile dysfunction and one patient experienced urinary incontinence after EBRT.

CONCLUSIONS

This study demonstrated the feasibility and safety of CivaSheet combined with RP and adjuvant EBRT for high-risk PCa. The short-term toxicity profile was well-tolerated, supporting further prospective evaluation with clinical trials.

Prospective longitudinal trajectory of cancer survivorship among patients with recurrent rectal cancer: impact of treatment modalities and resection status

AIM

Recurrent rectal cancer (RRC) can be morbid and optimising cancer survivorship is a priority. The longitudinal trajectories of survivorship associated with RRC have not been prospectively depicted.

METHODS

We prospectively enrolled patients with RRC. Participants self-reported quality of life (QOL) using validated European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 and CR29, and pain using the Brief Pain Inventory, at baseline and then every 6 months for up to 5 years or until death. Baseline scores and the longitudinal trajectory of scores were examined using linear mixed-effects modelling.

RESULTS

Among 104 patients, 73 (70.2%) received multimodality salvage treatment with curative intent, while the remainder received best palliative treatments. Curative-intent salvage including surgery was associated with a 30-day operative morbidity rate of 49% and a 5-year overall survival of 51%. Patients undergoing curative-intent salvage versus palliative treatments did not differ in baseline QOL or pain, but the longitudinal trajectory after curative-intent salvage showed sustained improvement of QOL and symptoms over time. This contrasted with the initial transient improvement but persistent decline with palliative treatments. Baseline QOL was significantly impacted by the anatomical site of RRC, with posterior location associated with worst QOL (P = 0.012). Long-term QOL was impacted by anatomical site and status of residual tumour. Pain scores were worse among men.

CONCLUSION

Trajectories of cancer survivorship for patients with RRC diverge, mainly influenced by anatomical site of the RCC, residual tumour status, and ability to complete curative-intent salvage. These should inform treatment planning. Optimising selection and success of multimodality therapy remains the cornerstone for durable cancer survivorship.

Renal Function in Sequential Living Kidney-Then-Liver Donors Undergoing Right Lobe Donation: A Two-Center Case Study

BACKGROUND

There are concerns regarding the potential impact of living donor hepatectomy on the kidney function of prior kidney donors. The current literature lacks comprehensive data on living liver following living kidney donation. Furthermore, the focus on left lobe donation in the literature does not fully represent the prevalent use of the right lobe graft for living liver transplants in the United States.

METHODS

We performed a retrospective chart review on all living liver donors who had previously donated a kidney at two US centers.

RESULTS

There were 14 sequential living kidney-then-liver donors. The median donor age was 49 years (range 35-59). Most of these (12 donors) were nondirected donations. The median follow-up period was 24 months (range 1-129). The median interval between the donations was 32 months (range 17-154 months). All donors donated the right lobe with 43.5% (range 31.4%-49.9 %) of remnant liver volume. The overall donor complication rate was 43%, seen in six donors, with one Clavien-Dindo Grade IIIa complication (suture granuloma removal under local anesthesia). Two donors (14%) experienced stage 1 AKI, both resolving with supportive care. A decrease in eGFR greater than 10 mL/min/1.73 m2 over the follow-up was observed in only one donor, who gained weight and was lost to follow-up. Compensatory kidney hypertrophy was observed, with kidney volumetry showing an increase of 1.27 (1.09-1.39) times pre- versus post-kidney donation and 1.08 times pre- versus post-liver donation (1.01-1.16).

CONCLUSIONS

Right lobe living liver donation in previous kidney donors might be safely performed in terms of midterm kidney function. Longer-term assessment in a larger cohort would be necessary to have better insight into this unique donor group.

The impact of body mass index on the risk of postoperative complications following myomectomy

BACKGROUND

Uterine leiomyomas are common benign neoplasms, often causing symptoms like abnormal uterine bleeding, pelvic pain, and subfertility, with treatment options ranging from medical management to surgical interventions such as myomectomy. While myomectomy is effective in symptom relief, the impact of body mass index (BMI) on postoperative complications remains underexplored, warranting further investigation.

OBJECTIVE

This study aimed to assess the relationship between BMI and short-term postoperative complications after myomectomy.

STUDY DESIGN

An analysis of major and minor 30-day postoperative complications stratified by BMI among patients who underwent abdominal or laparoscopic (conventional or robotic-assisted) myomectomy was conducted using data from the American College of Surgeons National Surgical Quality Improvement Program database from 2012 to 2020. Vaginal myomectomy cases were excluded from this study. Complications were stratified according to the Clavien-Dindo classification.

RESULTS

A total of 27,387 cases were included. Postoperative complications occurred in 11.4% of cases (n=3131), ranging from 9.4% among patients who were underweight (n=26) to 16.1% among patients with obesity class 3 (n=350) (P<.001). In multiple regression analysis, patients with obesity class 1 experienced fewer major postoperative complications (adjusted odds ratio, 0.71; 95% confidence interval, 0.53-0.96) than those with normal BMI. Conversely, patients with obesity class 2 demonstrated more complications (adjusted odds ratio, 1.18; 95% confidence interval, 1.03-1.35), including minor complications (adjusted odds ratio, 1.17; 95% confidence interval, 1.02-1.34), than those with normal BMI. In addition, patients with obesity class 3 demonstrated more complications (adjusted odds ratio, 1.26; 95% confidence interval, 1.08-1.47), including minor (adjusted odds ratio, 1.21; 95% confidence interval, 1.03-1.42) and major (adjusted odds ratio, 1.41; 95% confidence interval, 1.01-21.99) complications, than those with normal BMI. Similar outcomes were observed when analyzing abdominal myomectomy exclusively, with disparities being much less pronounced when the analysis was confined to laparoscopic myomectomy.

CONCLUSION

Patients with class 2 or 3 obesity are at increased odds of experiencing complications after myomectomy, whereas those with a slightly elevated body mass index may experience a protective effect. Complications related to BMI predominantly manifest after abdominal myomectomy procedures rather than after laparoscopic approaches.

Impact of intraoperative blood loss on postoperative morbidity after liver resection for primary and secondary liver cancer

BACKGROUND

We sought to determine the association between intraoperative blood loss (IBL) and postoperative morbidity among patients undergoing surgery for liver cancer.

METHODS

Patients undergoing surgery for primary and secondary liver cancer were identified from a multi-institutional database. Adjusted blood loss (aBL) was calculated by normalizing IBL to body weight; the comprehensive complication index (CCI) was used to evaluate postoperative complications.

RESULTS

A total of 2491 patients were included. Mean CCI was 10.6 (±5.2) for patients with aBL <10 mL/kg versus 15.2 (±7.2) for individuals with aBL ≥10 mL/kg (p < 0.001). On cubic spline regression, a nonlinear correlation between aBL and CCI was observed. CCI increased exponentially for aBL ranging from 5 to 10 mL/kg, then reached a plateau between an aBL of 10-30 mL/kg before dramatically increasing for aBL >30 mL/kg. Recursive partitioning technique demonstrated that an aBL threshold of 8.5 mL/kg best distinguished CCI (p < 0.001). Additionally, patients with an aBL ≥8.5 mL/kg had worse recurrence-free and overall survival versus patients with an aBL <8.5 mL/kg.

CONCLUSION

A nonlinear incremental correlation between aBL and CCI was identified among patients undergoing surgery for liver cancer. Maintaining an aBL <8.5 mL/kg during LR may help reduce postoperative morbidity.

Hysterectomy or not for borderline ovarian tumor in menopause?

BACKGROUND

The role of hysterectomy for borderline ovarian tumor (BOT) among postmenopausal women is still unclear.

OBJECTIVE(S)

To assess the impact of hysterectomy on survival outcomes in postmenopausal women with BOT.

STUDY DESIGN

This study was a national, multicenter, observational, retrospective, cohort study including all consecutive eligible postmenopausal patients who underwent primary surgery for BOT in 20 Italian centers from January 2005 to December 2017. Patients were divided into two groups: hysterectomy group vs no-hysterectomy group. Primary outcome was disease-free survival (DFS) at 5 years of follow-up; secondary outcomes were overall survival (OS) and disease-specific survival (DSS) at 5 years of follow-up, hazard ratio (HR) for recurrence, death of any cause and death due to BOT, peri-operative complications rates.

RESULTS

483 patients were included, 144 (29.8 %) women in the no-hysterectomy group and 339 (70.2 %) in the hysterectomy group. Recurrences were significantly more common in the no-hysterectomy group compared to hysterectomy one (8.3 % vs 2.7 %; p = 0.012). The 5-year DFS rate was lower in the no-hysterectomy group than that in the hysterectomy one [92.4 % vs 98.5 %; p = 0.007]. At univariate analyses, women who underwent hysterectomy showed HR of 0.312 (95 %CI:0.131-0.740; p = 0.008) for recurrence. At multivariate analysis, hysterectomy was found to be an independent protective factor for recurrence (HR: 0.253, 95 %CI:0.103-0.618, p < 0.003).

CONCLUSIONS

In postmenopausal women with BOT, hysterectomy is associated with a decreased risk of recurrence, while it does not affect the risk of death from any cause or death due to the disease. Based on these findings, hysterectomy should be routinely integrated into the surgical staging of BOT in postmenopausal women.

Adjuvant Chemotherapy Decisions in the Treatment of Lung Cancer Considering Nonrelapse Mortality: A Multicenter Study

BACKGROUND

Adjuvant chemotherapy (Adj) reduces recurrence and improves long-term survival in patients with surgically resected lung cancer. However, it has minimal impact on patients who die without relapsing. To optimize Adj indications, we aimed to identify factors associated with nonrelapse mortality (NRM).

PATIENTS AND METHODS

This multicenter, retrospective, observational study enrolled patients with surgically resected with stages II-III non-small cell lung cancer. Multivariable Cox regression analysis was performed to identify the factors associated with NRM and early-NRM within 2 years of surgery and to stratify the enrolled patients. Adj administration rates and postoperative overall and recurrence-free survival rates were compared. Multivariable competing regression analysis with NRM as a competing risk was used to assess the cumulative incidence of lung cancer-associated death and recurrence.

RESULTS

Through a scoring system assigning 1 point to each extracted factor (old age, male sex, poor performance status, nonadenocarcinoma, and occurrence of major complications), the 1,244 included patients were stratified into 3 groups based on scores of 0-5: A (0-1 points; n = 613), B (2-3 points; n = 549), and C (4-5 points; n = 62) with 53%, 26%, and 11% Adj administration, respectively. Although group A showed the highest overall and recurrence-free survival rates, competing regression analysis showed no significant differences in cumulative lung cancer-associated death and recurrence incidence between the groups.

CONCLUSION

Better prognosis in group A was attributed to lower NRM and higher Adj administration rates. While proactive Adj may benefit group A, careful evaluation is warranted for group C to optimize Adj indication.

Indocyanine green fluorescence navigation with 4K overlay vs. conventional laparoscopic liver resection: a propensity score-matched analysis (liver-light study)

INTRODUCTION

Laparoscopic liver resection (LLR) has revolutionized liver surgery by offering several advantages over traditional open procedures. However, conventional LLR (C-LLR) has certain limitations, such as the inability to palpate tumors and the need for continuous ultrasound guidance during surgery, which can result in complications. Real-time tumor-tracking technologies, such as indocyanine green (ICG) fluorescence imaging, have shown potential in enhancing tumor detection and improving perioperative outcomes. The Liver-Light study aims to evaluate the feasibility of integrating ICG fluorescence with 4 K imaging technology during LLR (ICG4K-LLR) to improve postoperative surgical and oncological outcomes.

METHODS

This study is a prospective, single-center investigation that included 42 patients who underwent ICG4K-LLR. These patients were matched in a 1:1 ratio using propensity scores with patients from retrospective data who underwent C-LLR. Potential confounding factors, including sex, age, body mass index, tumor type, and the complexity of LLR, were selected for matching. Postoperative surgical and oncological outcomes were then compared between the two groups.

RESULTS

After propensity score-matched analysis, the ICG4K-LLR group demonstrated several significant advantages over the C-LLR group. Operation times were shorter in the ICG4K-LLR group (155.2 min vs. 196.6 min, p = 0.002), with reduced blood loss (300.0 ml vs. 501.2 ml, p = 0.006) and fewer blood transfusions (0% vs. 14.3%, p = 0.011). Additionally, no patients in the ICG4K-LLR group had positive resection margins, whereas 14.3% of patients in the C-LLR group did (p = 0.011). The incidence of clinically relevant posthepatectomy liver failure (p = 0.040) and major morbidity (p = 0.035) was significantly lower in the ICG4K-LLR group. Furthermore, the 1-year disease free survival rate was significantly higher in the ICG4K-LLR group (92.3% vs. 64.3%, p = 0.004).

CONCLUSION

ICG4K-LLR has a promising potential as a safe and effective navigation system, offering improved perioperative surgical and oncological outcomes compared to C-LLR.

Frailty Index as a Predictor of Operative Safety and Efficacy in Patients Undergoing Laparoscopic Sleeve Gastrectomy

BACKGROUND

Bariatric surgery is an effective treatment for obesity and its associated comorbidities. However, the safety and efficacy of laparoscopic sleeve gastrectomy (LSG) for elderly and frail populations remain uncertain.

OBJECTIVES

To validate the efficacy and safety of LSG for elderly and frail patients and to assess its impact on overweight and obesity-related comorbidities.

METHODS

A retrospective cohort study of patients undergoing LSG at a university-affiliated single center between 2009 and 2022 from a prospectively maintained database. Patients were categorized into two cohorts based on age and frailty index: elderly vs younger patients and frail vs non-frail groups. Preoperative, perioperative, and postoperative data were analyzed.

RESULTS

Frailty was associated with statistically significantly higher perioperative complications (%, Clavien-Dindo of III/IV, 8 vs 3) and lower treatment success rates (% Excess Body Weight Loss, six-month, year, and two-year, 58 vs 64, 73 vs 82, 72 vs 81, and 63 vs 76, respectively). Age was not shown to alter the safety or efficacy of the operation.

CONCLUSION

While LSG is a viable option for elderly and frail patients, frailty is a significant predictor of treatment outcomes. A comprehensive assessment of individual factors, including frailty status, is essential for informed decision-making before surgery.

Risk Analysis Index for Estimation of 30-Day Postoperative Mortality in Hip Fractures

Importance

Hip fractures present a substantial public health challenge, with projections of more than 500 000 per year by 2040. As such, frailty indices such as the Revised Risk Analysis Index (RAI) and the Modified Five-Item Frailty Index (mFI-5) have been recently investigated as metrics for preoperative risk stratification for these patients.

Objective

To understand the accuracy of frailty, as measured by the RAI and the mFI-5, for estimating 30-day mortality following surgically managed hip fractures.

Design, Setting, and Participants

This retrospective cross-sectional analysis used the American College of Surgeons' National Surgical Quality Improvement database. Patients aged 65 years old with surgically managed traumatic hip fracture from 2015 to 2019 were included. Frailty was evaluated using the RAI, a 5-domain scale with 14 weighted variables graded from 0 to 81, and the mFI-5, a 2-domain scale with 5 unweighted variables graded from 0 to 5; for both, a higher score denotes worse frailty. Data collection occurred from May to June 2024.

Exposure

Diagnosis of hip fracture and undergoing surgical fixation, hemiarthroplasty, or total hip arthroplasty.

Main Outcomes and Measures

The primary outcome was 30-day mortality. Multivariable regression was conducted to assess the estimating value of frailty scales. Discriminatory accuracy was assessed using a receiver operating characteristic curve and quantified using a C-statistic.

Results

The cohort consisted of 114 359 patients (70 038 female [69.9%]; median [IQR] age, 84 [77-89] years) with 51 071 prefrail patients (44.7%) according to the mFI-5 and 31 883 very frail patients (27.9%) according to the RAI comprising the largest frailty groups. Increasing frailty status was associated with greater odds ratio (OR) for 30-day mortality for both the mFI-5 (prefrail OR, 1.35 [95% CI, 1.24-1.47]; frail OR, 2.11 [95% CI, 1.94-2.30]; severely frail OR, 3.53 [95% CI, 3.20-3.90]; P < .001 for all) and RAI (normal OR, 1.55 [95% CI, 1.35-1.79]; frail OR, 2.97 [95% CI, 2.59-3.42]; very frail OR, 6.17 [95% CI, 5.38-7.08]; P < .001 for all). The RAI demonstrated superior discriminatory accuracy for 30-day mortality compared with the mFI-5 (area under the receiver operating characteristic curve, 0.73 [95% CI, 0.72-0.73] vs 0.61 [95% CI, 0.60-0.62]; P < .001).

Conclusions and Relevance

In this cross-sectional study of 114 359 patients, the RAI demonstrated superior odds and discriminatory accuracy for estimating 30-day mortality following surgical management of hip fractures. The RAI may be considered as a risk stratification tool for orthopedic surgeons to adjunct surgical planning, thereby reducing postoperative mortality.

Enhanced Recovery Independently Lowers Failure to Rescue After Colorectal Surgery

BACKGROUND

High adherence to the enhanced recovery after surgery pathway reduces morbidity and mortality rates after elective colorectal surgery.

OBJECTIVE

To evaluate the effect of adherence to the enhanced recovery after surgery pathway on the failure to rescue rates after elective colorectal surgery.

DESIGN

Retrospective analysis of a prospective database.

PATIENTS

Adults (18 years or older) who underwent elective colorectal resection with anastomosis for benign and malignant disease.

SETTINGS

Prospective enrollment in 78 centers in Italy from 2019 to 2021.

INTERVENTIONS

All outcomes were measured 60 days after surgery. Several patient-, disease-, treatment-, hospital-, and complication-related variables were analyzed. After univariate analyses, independent predictors of the end points were identified through logistic regression analyses, presenting ORs and 95% CIs.

MAIN OUTCOME MEASURES

Failure to rescue after any adverse event, defined as the ratio between the number of deaths and the number of patients showing any adverse event; failure to rescue after any major adverse event, with the denominator represented by the number of patients showing any major adverse event.

RESULTS

An adverse event was recorded in 2321 of 8359 patients (27.8%), a major adverse event in 523 patients (6.3%), and death in 88 patients (1.0%). The failure to rescue rates were 3.8% after any adverse event and 16.8% after any major adverse event. Independent predictors of primary end points were identified among patient- (age, ASA class, and nutritional status), treatment- (type of resection), and complication-related (anastomotic leakage and reoperation) variables. Enhanced recovery pathway adherence of more than 70% independently reduced failure to rescue rates.

LIMITATIONS

Clustering from multicenter data and unmeasured confounding from observational data.

CONCLUSIONS

After elective colorectal resection, adherence of more than 70% to the enhanced recovery pathway independently decreased failure to rescue rates, along with other patient- or treatment-related factors. See Video Abstract .

Cystopexy raises the post-operative complication rate during laparoscopic hysterectomy for uterine prolapse

Objectives

This study aims to compare the outcomes of laparoscopic colposuspension sec Shull (LCSS) and laparoscopic colposacropexy (LCSP) with and without the addition of cystopexy for the treatment of pelvic organ prolapse (POP) in terms of postoperative complications, recurrence rates, and overall effectiveness.

Materials and methods

A retrospective case-control analysis was conducted on women treated for grade 3-4 POP-Q uterine prolapse at the Academic Departments of Gynaecology and Obstetrics of "G. Martino" of Messina, Italy, and "L. Vanvitelli" of Napoli, Italy, between November 2020 and February 2022. Group A consisted of patients who underwent laparoscopic hysterectomy followed by LCSS or LCSP without cystopexy. At the same time, Group B included patients who had the same procedures with the addition of cystopexy. Data on complications were collected using the Clavien-Dindo classification, and prolapse recurrence was monitored according to the POP-Q system. Statistical analysis was performed using Fisher's exact, Chi-squared, and Wilcoxon rank-sum tests.

Results

A total of 148 patients were included, with 125 in Group A and 23 in Group B. Group B showed a significantly higher rate of postoperative complications (16%) compared to Group A (2.4%) (p = 0.016), with an Odds Ratio of 7.62 (95% CI 1.59-36.51, p = 0.0017). No significant difference between the groups was found in the recurrence rate of prolapse at 24 months (p > 0.9).

Conclusion

Adding cystopexy to LCSS or LCSP increases the risk of postoperative complications without reducing prolapse recurrence rates. Further research is needed to identify patients who may benefit from cystopexy and to evaluate its impact on stress incontinence and patient satisfaction.

The impact of preoperative immunonutritional status on postoperative complications in ovarian cancer

BACKGROUND

Preoperative immunonutritional status can influence postoperative complications. Malnutrition in ovarian cancer patients diminishes the body's resilience to abdominal surgery, resulting in inferior surgical outcomes and increased postoperative complications. We aim to investigate the effect of preoperative immunonutritional status, including NLR, PLR, LMR, TCLR, FAR, FLR, SII, PNI and CONUT on postoperative complications in epithelial ovarian cancer (EOC) in a large population.

METHODS

A multicenter real-world study included 922 patients with histologically confirmed EOC who received comprehensive staged surgery or debulking surgery at seven tertiary hospitals in China between 2012 and 2023. Logistic regression and Lasso regression analyses were employed to identify variables associated with postoperative complications. A predictive nomogram model was developed based on multivariate modeling.

RESULTS

The study included a total of 922 patients diagnosed with epithelial ovarian cancer across seven medical centers with 565 (61.3%) patients experiencing postoperative complications. Significant differences were found in the distribution of inflammatory and nutritional risk indicators, including NLR, PLR, LMR, TCLR, FAR, FLR, SII, PNI and CONUT between the two groups (all P < 0.01). A multivariable model identified several predictive factors for postoperative complications: PNI > 46.73 (odds ratio [OR] = 0.49, P < 0.001), FAR > 10.77 (OR = 1.60, P = 0.019), LMR > 3.70 (OR = 0.68, P = 0.044), hydrothorax (OR = 2.60, P = 0.005), laparoscopy (OR = 0.59, P = 0.010 vs. laparotomy), enterectomy (OR = 2.50, P = 0.001).

CONCLUSION

Poor immunonutritional status can increase the risk of postoperative complications. These findings suggest that prompt nutritional interventions may reduce the incidence of postoperative complications and improve surgical outcomes. The risk prediction model, including PNI, FAR, LMR, hydrothorax, laparoscopy vs. laparotomy, and enterectomy, might facilitate patient-centered decision-making and risk stratification.

Safety of Same-Day Discharge Bariatric Surgery: A Comprehensive Analysis of 457 Cases Across Multiple Procedure Types

BACKGROUND

Outpatient bariatric surgery offers reduced hospital stays and healthcare costs, with promising safety outcomes. This study analyzes the short-term results of stand-alone primary and revision bariatric surgeries, alongside concomitant foregut and abdominal surgeries associated with bariatric procedures, to assess their safety and efficacy in an outpatient setting at a free-standing ambulatory center.

METHODS

A retrospective study was conducted on 457 same-day discharge (SDD) bariatric cases performed by a single surgeon at a free-standing ambulatory center between January 2021 and July 2024. The procedures included sleeve gastrectomy (SG), duodenal switch (DS), adjustable gastric band (AGB) removal, and Roux-en-Y gastric bypass (RYGB). Concomitant foregut and abdominal surgeries associated with bariatric procedures, such as hiatal hernia repair (HHR), cholecystectomy, fundoplication, and ventral hernia repair, were performed when clinically indicated.

RESULTS

Of the 457 cases, 97.8% were primary surgeries, and 2.1% were revisions. Stand-alone procedures accounted for 39.3%, and 60.6% were concomitant. SG constituted 74.8% of cases, followed by HHR (16.1%), DS (5.4%), AGB removal (2.6%), and RYGB (.8%). The mean operative time was 79.9 ± 24.3 min, with a mean length of stay of 3 h 52 min (± 1:10). The 30-day complication rate was 2.1%, with Clavien-Dindo grade IIIb complications in .8% of patients. Patient satisfaction was high, with a mean score of 9.8.

CONCLUSIONS

Outpatient bariatric surgeries demonstrated strong safety with minimal complications, underscoring their viability in carefully selected patients. Staged approaches for complex cases further optimized outcomes, making outpatient settings a robust option for a wide range of bariatric procedures.

Is preoperative smoking status a predictor of postoperative outcomes after esophagectomy for squamous cell carcinoma in a high-volume centre?

BACKGROUND

Smoking is a major risk factor for esophageal squamous cell carcinoma (ESCC) and is linked to increased postoperative morbidity. However, its impact on long-term survival remains unclear. This study evaluated the influence of preoperative smoking status on postoperative complications and survival following esophagectomy for ESCC in a high-volume center.

METHODS

Patients who underwent surgery for ESCC between 1996 and 2019 were retrospectively categorized as smokers (S-group) or non-smokers (NS-group). A subgroup analysis was performed to compare active and former smokers. Primary outcomes included major postoperative complications (Clavien-Dindo ≥ III), pulmonary complications, and postoperative mortality at 30 and 90 days. Long-term outcomes included overall survival (OS) and recurrence-free survival (RFS).

RESULTS

Among 694 patients, 97 (14%) were in the NS-group and 597 (86%) in the S-group. Smokers had significantly higher major morbidity rates (37% vs 23%, P = .002), including major pulmonary complications (29% vs 21%, P = .03). Active smoking was associated with increased 30-day mortality (P = .006) and higher rates of acute respiratory distress syndrome (P = .012) compared to former smokers. OS and RFS did not differ significantly between groups. The absence of post-operative smoking data limits long-term outcome interpretation.

CONCLUSION

Smoking was associated with increased perioperative morbidity, particularly pulmonary complications, but its effect on long-term survival remains uncertain. Structured smoking cessation programs should be integrated into perioperative care. Future studies should incorporate postoperative smoking status to better assess its impact on survival.

First-in-human side-to-side linear magnetic compression gastroileostomy: feasibility and early outcomes in adults with obesity

BACKGROUND

Conventional surgical stapling/suturing requires tissue fixation with retained potentially inflammatory materials. A novel minimally invasive magnetic compression anastomosis system that requires no fixation, enterotomy closure, or permanent implant seems to mitigate major complications associated with stapling/suturing. As an option for revision of clinically suboptimal sleeve gastrectomy (SG), the technical feasibility, safety, and preliminary efficacy of magnetic gastroileostomy bipartition (MagGI procedure) were evaluated in a first-in-human case series.

METHODS

In this prospective single-center study, adults with a body mass index (BMI) of ≥30.0 to ≤50.0 kg/m2 who were candidates for SG revision underwent the MagGI procedure. A distal magnet was delivered endoscopically with laparoscopic assistance to the ileum. A proximal magnet was positioned endoscopically in the gastric antrum. The magnets were aligned to gradually fuse, forming a gastroileal bipartition. The primary safety endpoint was minimal incidence of device- and procedure-related severe adverse events (SAEs) (Clavien-Dindo [CD] classification). The primary efficacy endpoint was technical feasibility. The secondary endpoints were reduction of weight and metabolic parameters.

RESULTS

Between November 27, 2023, and May 27, 2024, 7 patients (mean BMI of 38.8 ± 0.9 kg/m2) underwent revisional MagGI. Feasibility was demonstrated, and patent gastroileal anastomoses were confirmed in 100.0% of cases, with no device-related events and 1 SAE with a CD III mild rating. There was no anastomotic leakage, bleeding, obstruction, infection, or stricture. Total weight loss and excess weight loss were 18.9% ± 3.9% and 52.4% ± 11.0%, respectively. A BMI reduction of 7.4 kg/m2 was observed (P <.05). Mild nutritional concerns were treated.

CONCLUSION

At the 6-month interim evaluation, the MagGI procedure was performed to revise clinically suboptimal SG. In addition, the procedure was technically straightforward, incurred no major complications, and renewed clinically meaningful weight loss in a small cohort.

Efficacy, safety and single-cell analysis of neoadjuvant immunochemotherapy in locally advanced oral squamous cell carcinoma: a phase II trial

The clinical activity of neoadjuvant immunochemotherapy (NAIC) for treating locally advanced oral squamous cell carcinoma (LA-OSCC) remains uncertain. This single-arm, phase II trial (ChiCTR2200066119) tested 2 cycles of NAIC with camrelizumab plus nab-paclitaxel and cisplatin in LA-OSCC patients. For primary endpoint, the major pathological response (MPR) rate was 69.0% (95% confidence interval (CI): 49.2%-84.7%). The treatment was well-tolerated, with only 2 patients (6.45%) having grade 3 or 4 treatment-related adverse events during neoadjuvant treatment. For secondary endpoints, the pathological complete response rate was 41.4% (95%CI: 23.5%-61.1%) and the objective response rate was 82.8% (24/29, 95%CI: 64.2%-94.2%). The 18-month overall survival and disease-free survival probabilities were 96.77% (95%CI: 79.23%-99.54%) and 85.71% (95%CI: 53.95%-96.22%), respectively. Exploratory analysis showed that patients with MPR exhibited higher density of baseline CD4_Tfh_CXCL13 cells, and increased density of tertiary lymphoid structures after NAIC. Baseline CD4_Tfh_CXCL13 cells might be potential predictive biomarker of efficacy. The interaction between CXCL13 on CD4_Tfh_CXCL13 cells and CXCR5 on B cells may play a role in treatment response. These findings suggest the potential of NAIC as a promising treatment for LA-OSCC and offer preliminary insights into responsive biomarkers.

Handedness and Laterality in Plastic Surgery and Outcome-A Retrospective, Two-Center, Evaluator-Blinded Study

BACKGROUND

Little is known about the influence of handedness on the outcome of operations in plastic surgery. Our study addresses the question of whether there is a difference between the right and left sides in the outcome of plastic surgeries in relation to the handedness of the surgeon.

PATIENTS AND METHODS

In this retrospective two-center study, patients undergoing plastic surgery on bilateral locations (breast reduction, mastopexy, augmentation mastopexy, blepharoplasty, mastectomy on gynecomastia, brachioplasty, thigh lift) between January 2020 and December 2023 were included. The outcome was assessed separately by an independent assessor. The Likert scale (1-10) was used as the standardized assessment method for the study data. Additionally, complications were classified as minor or major complications, depending on whether a reoperation was necessary or not.

RESULTS

During the study period, 61 patients (four men and 57 women) were included (mean age 44 years, range 18-83 years) with a mean follow-up of 9.3 months (range 1-28 months). There was no statistically significant difference between both sides (p = 0.60) with a positive trend toward the right side. There were no major complications and 12 minor complications (19.7%) with a tendency to a higher complication rate on the right side.

CONCLUSION

Our results indicate that handedness may play a minor role in the outcome of plastic surgeries. Nevertheless, ergonomic measurements can be made in order to optimize the outcome. Moreover, it might be necessary to include ambiguity in handedness to improve the overall outcome.

Perioperative enhanced recovery after surgery (ERAS) for non-malignant gynaecological conditions

OBJECTIVES

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the effects of perioperative ERAS protocols compared to traditional perioperative care for women undergoing surgery due to non-malignant gynaecological conditions and to review the availability and key findings of health economic evaluations of ERAS, summarising their principal conclusions.

Minimally invasive radical prostatectomy versus open radical prostatectomy: A systematic review and meta-analysis of randomized control trials

OBJECTIVE

To evaluate the comparative outcomes of Minimally Invasive Radical Prostatectomy (MIRP) versus Open Radical Prostatectomy (ORP) to treat localized prostate cancer, using only Randomized Controlled Trials (RCTs) to ensure high-quality evidence.

METHOD

A systematic review and meta-analysis were conducted in accordance with PRISMA guidelines, focusing solely on RCTs comparing MIRP (robot-assisted or laparoscopic surgery) and ORP. Literature searches across multiple databases, including Cochrane Library, Medline, Embase, Lilacs, Scopus, Web of Science, NIH, Clinical Trials, and EU Clinical Trials Register, identified studies meeting predefined PICOT criteria. Four RCTs met inclusion criteria ‒ two representing the same cohort of patients ‒ and were analyzed for perioperative, functional, and oncologic outcomes. Quality assessment utilized the ROB-2 tool to gauge the risk of bias.

RESULTS

Three RCTs encompassing 1051 patients were analyzed. MIRP demonstrated statistically significant benefits over ORP in terms of reduced perioperative blood loss (Standardized Mean Difference [SMD = -3.058], p = 0.006), lower transfusion rates (Odds Ratio [OR = 0.137]; p = 0.009), and fewer overall complications (OR = 0.465; p = 0001). However, no significant differences were found in long-term oncologic and functional outcomes, including urinary continence and erectile function. Positive surgical margins and additional treatments also did not differ significantly between groups.

CONCLUSION

This systematic review and meta-analysis of RCTs indicated that MIRP offers perioperative advantages over ORP, supporting its role as a safe and effective option for localized prostate cancer.

Impact of osteosarcopenia on short- and long-term outcomes in patients with gastric cancer

BACKGROUNDS

Osteopenia and sarcopenia are associated with adverse clinical outcomes. This study investigated the impact of osteosarcopenia on short- and long-term outcomes after gastrectomy for gastric cancer.

METHODS

The present study included patients who underwent gastrectomy for gastric cancer. Osteopenia was evaluated by bone mineral density measurement in the midvertebral core of the 11th thoracic vertebra on preoperative computed tomography images. Sarcopenia was evaluated by measuring the skeletal muscle cross-sectional area at the third lumbar vertebra level. Osteosarcopenia was defined as the coexistence of osteopenia and sarcopenia. We investigated the relationship of preoperative osteosarcopenia with short- and long-term outcomes after gastrectomy for gastric cancer.

RESULTS

Of all 122 patients, 38 (31%) patients were diagnosed with osteosarcopenia. Multivariate logistic regression analysis revealed that osteosarcopenia (P = .008) was an independent risk factor for postoperative complications. Furthermore, multivariate Cox regression analysis revealed that male sex (P = .007), and osteosarcopenia (P = .038) were independent predictors of disease-free survival, while osteosarcopenia (P = .045) and pathological T stage ≥3 (P = .033) were independent predictors of overall survival.

CONCLUSIONS

Osteosarcopenia was a strong predictor of short- and long-term outcomes after gastrectomy for gastric cancer. Preoperative screening of osteosarcopenia may be helpful for better management of patients with gastric cancer.

Venous thromboembolism in patients undergoing pancreatic cancer surgery (PaTR-VTE) with curative intent; protocol of a prospective observational study

BACKGROUND

Pancreatic cancer is probably the most thrombotic malignancy, with an incidence of venous thromboembolism (VTE) of up to 18%. However, the exact pathophysiological mechanisms involved in the development of VTE in the setting of pancreatic cancer are not yet well understood. The primary endpoint of the study is to evaluate the neutrophil/lymphocyte ratio (NLR) and other coagulation biomarkers as predictors of VTE in patients with pancreatic cancer undergoing surgery with curative intent. The exact incidence of VTE, perioperative coagulation status of patients and the possible determinants of VTE in the aforementioned population are the secondary study objectives.

METHODS

This prospective, non-interventional observational study is conducted according to the STROBE concept. It has been approved by the ethical committee and registered (NCT05964621) and will include eligible patients with primary pancreatic cancer with resectable or borderline resectable disease undergoing surgery with curative intent. Exclusion criteria are: Refusal to participate, previous thromboembolic event < 6 months, ASA score > 3, patients deemed inoperable intraoperatively and the concurrent presence of a second primary malignancy. Three blood samples are taken from all patients (preoperatively, immediately after the operation, and before discharge) and the serum values of the following parameters are determined: Haemoglobin, white blood cells, INR, liver and kidney function tests, von Willebrand factor, factors VIII and XI, D-dimers, fibrinogen, platelet function, Adamts 13 and anti-Xa. One month after the procedure, scheduled screening for asymptomatic deep vein thrombosis (DVT) is performed with a lower extremity ultrasound triplex study. In addition, thromboembolic events (DVT, pulmonary embolism (PE)) diagnosed during the hospital stay period are recorded. Low molecular weight heparin will be routinely administered from the first postoperative day, with the dosage, i.e. prophylactic or therapeutic titrated according to the patient's history of cardiovascular disease. According to the literature, the pooled specificity of the admission NLR for 30-day VTE and PE prediction is 80.5%, while the VTE rates after pancreatectomy is 1.5%. Based on a 95% confidence level and a precision of 0.1, the estimated sample size for the specificity outcome is 62 patients.

DISCUSSION

The aim of this study is to identify predictors of postoperative VTE in patients undergoing pancreatic cancer surgery. The results could lead to an optimization of perioperative care.

Donor-Derived Bacterial Infections in Deceased Donor Liver Transplantation: Reassessment of Risk in the Era of Marginal Grafts

BACKGROUND

The shortage of available organs for liver transplant has, over time, led to the inclusion of donors at risk of transmitting bacterial infections. In Italy, depending on the severity of this risk, these organs are only allocated to patients in serious clinical conditions, consequently, their use in a shortage context is further restricted.

METHODS

We retrospectively analyzed a consecutive series of 194 liver transplants from deceased adult donors performed at our institute between 2019 and 2021 and performed a statistical comparison between 2 groups: recipients of livers with a risk of transmission of bacterial infection (BR group) vs recipients of livers with no risk (noBR group). Primary endpoints include 90-day and 1-year survival rates of recipients, and secondary endpoints focus on the incidence of complications of grade ≥3 according to Clavien-Dindo and donor-related infections.

RESULTS

Ninety-day and 1-year mortality in the BR vs noBR group was 5% vs 7% and 5% vs 14%, respectively. Major complications at 90 days occurred in 37% of the BR group vs 47% in the noBR group. No statistical differences were observed in the 2 recipient groups with respect to clinical outcomes. Cases of donor-derived infections also occurred in the noBR group.

CONCLUSIONS

Organs at risk of transmitting bacterial infections have comparable outcomes to other organs when appropriate risk reduction strategies are implemented. It is necessary to remove restrictions on these organs, which are becoming increasingly common in our shortage context.
