Abstract
BACKGROUND Avoiding missed diagnosis and therapeutic delay for significant blunt bowel and mesenteric injuries (sBBMIs) after trauma is still challenging despite the widespread use of computed tomography (CT). Several scoring tools aiming at reducing this risk have been published. The purpose of the present work was to assess the incidence of delayed (>24 hours) diagnosis for sBBMI patients and to compare the predictive performance of three previously published scores using clinical, radiological, and laboratory findings: the Bowel Injury Prediction Score (BIPS) and the scores developed by Raharimanantsoa Score (RS) and by Faget Score (FS). METHODS A population-based retrospective observational cohort study was conducted; it included adult trauma patients after road traffic crashes admitted to Lausanne University Hospital, Switzerland, between 2008 and 2019 (n = 1,258) with reliable information about sBBMI status (n = 1,164) and for whom all items for score calculation were available (n = 917). The three scores were retrospectively applied on all patients to assess their predictive performance. RESULTS The incidence of sBBMI after road traffic crash was 3.3% (38 of 1,164), and in 18% (7 of 38), there was a diagnostic and treatment delay of more than 24 hours. The diagnostic performances of the FS, the RS, and the BIPS to predict sBBMI, expressed as the area under the receiver operating characteristic curve, were 95.3% (95% confidence interval [CI], 92.7-97.9%), 89.2% (95% CI, 83.2-95.3%), and 87.6% (95% CI, 81.8-93.3%) respectively. CONCLUSION The present study confirms that diagnostic delays for sBBMI still occur despite the widespread use of abdominal CT. When CT findings during the initial assessment are negative or equivocal for sBBMI, using a score may be helpful to select patients for early diagnostic laparoscopy. The FS had the best individual diagnostic performance. However, the BIPS or the RS, relying on clinical and laboratory variables, may be helpful to select patients for early diagnostic laparoscopy when there are unspecific CT signs of bowel or mesenteric injury. LEVEL OF EVIDENCE Prognostic and Epidemiological; Level III.

Abstract
The macroscopic appearance of a tumor such as hepatocellular carcinoma (HCC) may be defined as its phenotype which is de facto dictated by its genotype. Therefore, macroscopic characteristics of HCC are unlikely random but rather reflect genomic traits of cancer, presumably acting as a valuable source of information that can be retrieved and exploited to infer prognosis. This review aims to provide a comprehensive overview of the available data on the prognostic value of macroscopic characterization in HCC. A total of 57 studies meeting eligible criteria were identified, including patients undergoing liver resection (LR; 47 studies, 83%) or liver transplant (LT; 9 studies, 16%). The following macroscopic variables were investigated: tumor size (n = 42 studies), number of nodules (n = 28), vascular invasion (n = 24), bile duct invasion (n = 6), growth pattern (n = 15), resection margin (n = 11), tumor location (n = 6), capsule (n = 2) and satellite (n = 1). Although the selected studies provided insightful data with notable prognostic performances, a lack of standardization and substantial gaps were noted in the report and the analysis of gross findings. This topic remains incompletely covered. While the available studies underscored the value of macroscopic variables in HCC prognostication, important lacks were also observed. Macroscopic characterization of HCC is likely an underexploited source of prognostic factors that must be actively explored by future multidisciplinary research.

Abstract
BACKGROUND Although neoadjuvant chemoradiation (nCRT) followed by surgery is standard treatment for locally advanced esophageal or gastroesophageal junction (E/GEJ) cancer, the optimal radiation dose is still under debate. OBJECTIVE The aim of this study was to assess the impact of different preoperative radiation doses (41.4 Gy, 45 Gy or 50.4 Gy) on pathologic response and survival in E/GEJ cancer patients. METHODS All consecutive patients with E/GEJ tumors, treated with curative intent between January 2009 and December 2016 in two referral centers were divided into three groups (41.4 Gy, 45 Gy and 50.4 Gy) according to the dose of preoperative radiotherapy. Pathologic complete response (pCR) rates, postoperative morbidity, overall survival (OS) and disease-free survival (DFS) were compared among the three groups, with separate analyses for adenocarcinoma (AC) and squamous cell carcinoma (SCC). RESULTS From the 326 patients analyzed, 48 were included in the 41.4 Gy group (14.7%), 171 in the 45 Gy group (52.5%) and 107 in the 50.4 Gy group (32.8%). Postoperative complication rates were comparable (p = 0.399). A pCR was observed in 15%, 30%, and 34% of patients in the 41.4 Gy, 45 Gy and 50.4 Gy groups, respectively (p = 0.047). A 50.4 Gy dose was independently associated with pCR (odds ratio 2.78, 95% confidence interval 1.10-7.99) in multivariate analysis. Within AC patients, pCR was observed in 6.2% of patients in the 41.4 Gy group, 29.2% of patients in the 45 Gy group, and 22.7% of patients in the 50.4 Gy group (p = 0.035). No OS or DFS differences were observed. CONCLUSIONS A pCR was less common after a preoperative radiation dose of 41.4 Gy in AC patients. Radiation dose had no impact on postoperative morbidity, long-term survival, and recurrence.

Abstract
BACKGROUND Few studies have assessed enhanced recovery after surgery (ERAS) in liver surgery for cirrhotic patients. The present meta-analysis assessed the impact of ERAS pathways on outcomes after liver surgery in cirrhotic patients compared to standard care. METHODS A literature search was performed on PubMed/MEDLINE, Embase, and the Cochrane Library. Studies comparing ERAS protocols versus standard care in cirrhotic patients undergoing liver surgery were included. The primary outcome was post-operative complications, while secondary outcomes were mortality rates, length of stay (LoS), readmissions, reoperations, and liver failure rates. RESULTS After evaluating 41 full-text manuscripts, 5 articles totaling 646 patients were included (327 patients in the ERAS group and 319 in the non-ERAS group). Compared to non-ERAS care, ERAS patients had less risk of developing overall complications (OR 0.43, 95% CI 0.31-0.61, p < 0.001). Hospitalization was on average 2 days shorter for the ERAS group (mean difference - 2.04, 95% CI - 3.19 to - 0.89, p < 0.001). Finally, no difference was found between both groups concerning 90-day post-operative mortality and rates of reoperations, readmissions, and liver failure. CONCLUSION In cirrhotic patients, ERAS protocol for liver surgery is safe and decreases post-operative complications and LoS. More randomized controlled trials are needed to confirm the results of the present analysis.

Abstract
Background: Factors affecting morphological changes in the liver following selective internal radiation therapy (SIRT) are unclear, and the available literature focuses on non-anatomical volumetric assessment techniques in a lobar treatment setting. This study aimed to investigate quantitative changes in the liver post-SIRT using an anatomical volumetric approach in hepatocellular carcinoma (HCC) patients with different levels of treatment selectivity and evaluate the parameters affecting those changes. This retrospective, single-institution, IRB-approved study included 88 HCC patients. Whole liver, liver segments, tumor burden, and spleen volumes were quantified on MRI at baseline and 3/6/12 months post-SIRT using a segmentation-based 3D software relying on liver vascular anatomy. Treatment characteristics, longitudinal clinical/laboratory, and imaging data were analyzed. The Student's t-test and Wilcoxon test evaluated volumetric parameters evolution. Spearman correlation was used to assess the association between variables. Uni/multivariate analyses investigated factors influencing untreated liver volume (uLV) increase. Results: Most patients were cirrhotic (92%) men (86%) with Child-Pugh A (84%). Absolute and relative uLV kept increasing at 3/6/12 months post-SIRT vs. baseline (all, p ≤ 0.005) and was maximal during the first 6 months. Absolute uLV increase was greater in Child-Pugh A5/A6 vs. ≥B7 at 3 months (A5, p = 0.004; A6, p = 0.007) and 6 months (A5, p = 0.072; A6, p = 0.031) vs. baseline. When the Child-Pugh class worsened at 3 or 6 months post-SIRT, uLV did not change significantly, whereas it increased at 3/6/12 months vs. baseline (all p ≤ 0.015) when liver function remained stable. The Child-Pugh score was inversely correlated with absolute and relative uLV increase at 3 months (rho = -0.21, p = 0.047; rho = -0.229, p = 0.048). In multivariate analysis, uLV increase was influenced at 3 months by younger age (p = 0.013), administered 90Y activity (p = 0.003), and baseline spleen volume (p = 0.023). At 6 months, uLV increase was impacted by younger age (p = 0.006), whereas treatment with glass microspheres (vs. resin) demonstrated a clear trend towards better hypertrophy (f = 3.833, p = 0.058). The amount (percentage) of treated liver strongly impacted the relative uLV increase at 3/6/12 months (all f ≥ 8.407, p ≤ 0.01). Conclusion: Liver function (preserved baseline and stable post-SIRT) favored uLV hypertrophy. Younger patients, smaller baseline spleen volume, higher administered 90Y activity, and a larger amount of treated liver were associated with a higher degree of untreated liver hypertrophy. These factors should be considered in surgical candidates undergoing neoadjuvant SIRT.

Abstract
The Advanced Trauma Life Support (ATLS) approach is generally accepted as the standard of care for the initial management of severely injured patients. While whole body computed tomography (WBCT) is still considered a contraindication in haemodynamically unstable trauma patients, there is a growing amount of data indicating the absence of harm from cross sectional imaging in this patient group. Our study aimed to compare the early mortality of unstable trauma patients undergoing a WBCT during the initial workup with those who did not. Single-center retrospective observational study based on the local trauma registry including 3525 patients with an ISS > 15 from January 2008 to June 2020. We compared the 24-h mortality of injured patients in circulatory shock undergoing WBCT with a control group undergoing standard workup only. Inclusion criteria were the simultaneous presence of a systolic blood pressure < 100 mmHg, lactate > 2.2 mmol/l and base excess < - 2 mmol/l as surrogate markers for circulatory shock. To control for confounding, a propensity score matched analysis with conditional logistic regression for adjustment of residual confounders and a sensitivity analysis using inverse probability weighting (IPW) with and without adjustment were performed. Of the 3525 patients, 161 (4.6%) fulfilled all inclusion criteria. Of these, 132 (82%) underwent WBCT and 29 (18%) standard work-up only. In crude and matched analyses, no difference in early (24 h) mortality was observed (WBCT, 23 (17.4%) and no-WBCT, 8 (27.6%); p = 0.21). After matching and adjustment for main confounders, the odds ratio for the event of death at 24 h in the WBCT group was 0.36 (95% CI 0.07-1.73); p = 0.20. In the present study, WBCT did not increase the risk of death at 24 h among injured patients in shock. This adds to the growing data indicating that WBCT may be offered to trauma patients in circulatory shock without jeopardizing early survival.

Abstract
Background Day admission surgery (DAS) is meant to provide a better in-hospital experience for patients and to save costs by reducing the length of stay. However, in a prospective payment system, it may also reduce the reimbursement amount, leading to unintended incentives for hospitals. Methods Over a 4-month period in 2021 and based on predefined clinical and logistic criteria, patients from different surgical sub-specialties were identified to follow the institutional DAS program. Revenue-analysis was performed, considering the Swiss diagnosis-related group (SwissDRG) prospective payment policy. Revenue with DAS program was compared to revenue if patients were admitted the day prior surgery (No DAS) using nonparametric pooled bootstrap t-test. All other costs considered identical, an estimation of the average cost spared due to the avoidance of pre-operative hospitalization in the DAS setting was carried out using a micro-costing approach. Results Overall, 105 inpatients underwent DAS over the study period, totaling a revenue of CHF 1 209 840. Among them, 25 patients (24%) were low outliers due to the day spared from the DAS program and triggering a mean (SD) financial discount of Swiss Francs (CHF) 4192 (2835), yielding a total amount of CHF 105 435. DAS revealed a mean revenue of CHF 7320 (656), compared to CHF 11 510 (1108) if patients were admitted the day before surgery (No DAS, P = .007). Conclusion In a PPS, anticipation of financial penalties when implementing a DAS for all-comers is key to prevent an imbalance of the hospital equation if no financial criteria are used to select eligible patients. Promptly revising workflow to maintain constant fixed costs for a greater number of patients may be a valuable hedging strategy.

Abstract
PURPOSE Statin treatment has been shown in certain population studies and meta-analyses to improve survival of patients with pancreatic ductal adenocarcinoma (PDAC). This study assessed if patients with statin treatment had better overall survival (OS) and disease-free survival (DFS) after upfront pancreatoduodenectomy for PDAC. METHODS Consecutive PDAC patients were retrospectively collected from three centers in Europe and USA (study period: 2000-2017). Adult patients who underwent upfront pancreatoduodenectomy and survived the first 90 postoperative days were included. Patients with metastasis at diagnosis or with macroscopic incomplete resection were excluded. Patients were considered under statin if started at least one month before pancreatoduodenectomy. Survival rates were calculated using Kaplan-Meier method and compared with log-rank test. RESULTS A total of 496 patients were included. Median age was 67 years (IQR 59-75), 48% (n = 236) were women, and 141 patients (28%) received statin treatment already preoperatively. Patients with and without statin treatment were comparable in terms of demographics and pre-/intraoperative characteristics, except for age and pre-existing diabetes. Median OS and DFS were similar in patients with and without statin treatment (OS: 29, 95% CI 22-36 vs. 27 months, 95% CI 22-32, p = 0.370, DFS: 18, 95% CI 14-22 vs. 16 months, 95% CI 14-18, p = 0.430). On multivariable Cox regression, lymph node involvement (HR 1.9, 95% CI 1.6-2.2, p < 0.001), tumor differentiation (HR 1.3, 95% CI 1.1-1.6, p = 0.003), and postoperative chemotherapy (HR 0.5, 95% CI 0.4-0.7, p < 0.001) were predictors of OS, whereas statin treatment was not a prognostic factor (HR 0.9, 95% CI 0.7-1.2, p = 0.376). CONCLUSION In this international cohort of PDAC patients, statin treatment did not influence survival after upfront pancreatoduodenectomy. Nodal involvement, tumor differentiation, and postoperative chemotherapy were independent predictors of OS.

Abstract
BACKGROUND Uptake of ERAS® pathways for pancreatic surgery have been slow and impacted by low compliance. OBJECTIVE To explore global awareness, perceptions and practice of ERAS® peri-pancreatoduodenectomy (PD). METHODS A structured, web-based survey (EPSILON) was administered through the ERAS® society and IHPBA membership. RESULTS The 140 respondents included predominantly males (86.4%), from Europe (45%), practicing surgery (95%) at academic/teaching hospitals (63.6%) over a period of 10-20 years (38.6%). Most respondents identified themselves as general surgeons (68.6%) with 40.7% reporting an annual PD volume of 20-50 cases, practicing post-PD clinical pathways (37.9%), with 31.4% of respondents auditing their outcomes annually. Reduced medical complications, cost and hospital length of stay, and improved patient satisfaction were perceived benefits of compliance to enhancing-recovery. Multidisciplinary co-ordination was considered the most important factor in the implementation and sustainability of peri-PD ERAS® pathways, while reluctance to change among health care practitioners, difficulties in data collection and audit, lack of administrative support, and recruitment of an ERAS® dedicated nurse were reported to be important barriers. CONCLUSIONS The EPSILON survey highlighted global clinician perceptions regarding the benefits of compliance to peri-PD ERAS®, the importance of individual components, perceived facilitators and barriers, to the implementation and sustainability of these pathways.

Abstract
BACKGROUND AND OBJECTIVES Assessment of liver function is paramount before hepatectomy. This study aimed to assess future liver remnant function (FLR-F) using hepatobiliary scintigraphy (HBS) and to compare it to FLR volume (FLR-V) in the prediction of posthepatectomy liver failure (PHLF). The impact of volume and function gains were also assessed in patients undergoing portal vein embolization (PVE) or liver venous deprivation (LVD). METHODS All consecutive patients undergoing major hepatectomy between 02/2018 and 09/2021 with preoperative HBS were included. FLR-V was expressed as percentage of total liver volume and analyzed using preoperative computed tomography. FLR-V and FLR-F gains after embolization were expressed in percentage. Receiver operating characteristic analysis was performed to compare both methods in predicting PHLF. RESULTS Thirty-six patients were included. PVE and LVD were performed in 4 (11%) and 28 patients (78%), respectively. Overall, PHLF occurred in eight patients (22%). FLR-F gain after embolization showed significant ability to predict PHLF (area under the curve [AUC] = 0.789), with cut-off value of 150% showing a sensitivity of 1.00, a specificity of 0.42, and a negative predictive value of 1.00. CONCLUSION Preoperative HBS shows a high sensitivity to predict PHLF when HBS is performed twice to measure the function gain after venous embolization.

Abstract
BACKGROUND Over the past decade, Enhanced Recovery After Surgery (ERAS®) guidelines have been proven to simplify postoperative care and improve recovery in several surgical disciplines. The authors set out to create and launch an ERAS® program for cranial neurosurgery that meets official ERAS® Society standards. The authors summarize the successive steps taken to achieve this goal in two specific neurosurgical conditions and describe the challenges they faced. METHODS Pituitary neuroendocrine tumors (Pit-NET) resected by a transsphenoidal approach and craniosynostosis (Cs) repair were selected as appropriate targets for the implementation of ERAS® program in the Department of Neurosurgery. A multidisciplinary team with experience in managing these pathologies was created. A specialized ERAS® nurse coordinator was hired. An ERAS® certification process was performed involving 4 seminars separated by 3 active phases under the supervision of an ERAS® coach. RESULTS The ERAS® Pit-NET team included 8 active members. The ERAS® Cs team included 12 active members. Through the ERAS® certification process, areas for improvement were identified, local protocols were written, and the ERAS® program was implemented. Patient-centered strategies were developed to increase compliance with the ERAS® protocols. A prospective database was designed for ongoing program evaluation. Certification was achieved in 18 months. Direct costs and time requirements are reported. CONCLUSION Successful ERAS® certification requires a committed multidisciplinary team, an ERAS® coach, and a dedicated nurse coordinator.

Abstract
INTRODUCTION Diffuse-type gastric cancer (DTGC) is associated with poor outcome. Surgical resection margin status (R) is an important prognostic factor, but its exact impact on DTGC patients remains unknown. The aim of this study was to assess the prognostic value of microscopically positive margins (R1) after gastrectomy on survival and tumour recurrence in DTGC patients. METHODS All consecutive DTGC patients from two tertiary centers who underwent curative oncologic gastrectomy from 2005 to 2018 were analyzed. The primary endpoint was overall survival (OS) for R0 versus R1 patients. Secondary endpoints included disease-free survival (DFS), recurrence patterns as well as the overall survival benefit of chemotherapy in this DTGC patient cohort. RESULTS Overall, 108 patients were analysed, 88 with R0 and 20 with R1 resection. Patients with negative lymph nodes and negative margins (pN0R0) had the best OS (median 102 months, 95% CI 1-207), whereas pN + R0 patients had better median OS than pN + R1 patients (36 months 95% CI 13-59, versus 7 months, 95% CI 1-13, p < 0.001). Similar findings were observed for DFS. Perioperative chemotherapy offered a median OS of 46 months (95% CI 24-68) versus 9 months (95% CI 1-25) after upfront surgery (p = 0.022). R1 patients presented more often early recurrence (< 12 postoperative months, 30% vs 8%, p = 0.002), however, no differences were observed in recurrence location. CONCLUSION DTGC patients with microscopically positive margins (R1) presented poorer OS and DFS, and early tumour recurrence in the present series. R0 resection should be obtained whenever possible, even if other adverse biological features are present.

Abstract
PURPOSE This prospective study aimed to analyze the functional, biological, and radiological aspects of the pancreatic anastomosis 1 year after pancreatoduodenectomy (PD). METHODS From 2016 to 2019, patients with PD indication were screened. Questionnaires about pancreas insufficiency, fecal elastase tests, and magnetic resonance imaging (MRI) were performed before and 1 year after PD. RESULTS Twenty patients were prospectively included. The only difference between pre- and postoperative questionnaires was constipation (less frequent 1 year after PD). Median pre- and postoperative fecal elastase levels were 96 μg/g (IQR 15-196, normal value > 200) and 15 μg/g (IQR 15-26, p = 0.042). There were no significant differences in terms of main pancreatic duct (MPD) size (4, IQR 3-5 vs. 4 mm, IQR 3-5, p = 0.892), border regularity, stenosis, visibility, image improvement, and secondary pancreatic duct dilation before and after secretin injection. All patients but one (2 refused and 2 were lost to follow-up, 15/16, 94%) had a patent pancreaticojejunal anastomosis on 1-year MRI. CONCLUSION Although median 1-year fecal elastase was significantly lower than preoperatively, suggesting that exocrine secretion was altered, the anatomical outcome as assessed by MRI was excellent showing high patency rate (15/16, 94%) at 1 year. This emphasizes the difference between anatomy and function.

Abstract
Pancreatic cancer is a leading cause of cancer-related death, with a poor overall survival rate. Although certain risk factors have been identified, the origins of pancreatic cancer are still not fully understood. Surgical resection remains the primary curative treatment, but pancreatic surgery is still associated with high morbidity and mortality rates, and most patients will experience recurrence. The impact of pancreatic cancer on patients' quality of life is significant, with an important loss of healthy life in affected individuals. Traditional outcome parameters, such as length of hospital stay, do not fully capture what matters to patients during recovery. Patient-centered care is therefore central, and the patient's perspective should be considered in pre-operative discussions. Patient-reported outcome and experience measures (PROMs and PREMs) could play an important role in assessing patient perspectives, but standardized methodology for evaluating and reporting them is needed. This narrative review aims to provide a comprehensive overview of patient perspectives and different patient-reported measures in pancreatic cancer surgery. Understanding the patient perspective is crucial for delivering patient-centered care and improving outcomes for patients with pancreatic cancer.

Abstract
Although protein malnutrition (PM) is often reported after highly malabsorptive procedures, its exact incidence and mechanisms after Roux-en-Y gastric bypass (RYGB) are poorly understood. The aim of this study was to present a challenging clinical case of PM after RYGB and conduct a scoping review of the literature. Among the 18 studies with 3015 RYGB patients included in the review, the median incidence of PM was 1.7% (range, 0%-8.9%), and it was diagnosed 12 to 120 months after RYGB. The most common cause is insufficient oral intake of protein; however, in cases of persistent hypoalbuminemia, a thorough diagnostic workup needs to be performed. Risk factors for PM after RYGB include specific triggering events such as intractable vomiting and dysphagia, and a total alimentary limb length less than 250 to 300 cm.

Abstract
Background The team timeout (TTO) is a safety checklist to be performed by the surgical team prior to incision. Exchange of critical information is, however, important not only before but also during an operation and members of surgical teams frequently feel insufficiently informed by the operating surgeon about the ongoing procedure. To improve the exchange of critical information during surgery, the StOP?-protocol was developed: At appropriate moments during the procedure, the leading surgeon briefly interrupts the operation and informs the team about the current Status (St) and next steps/objectives (O) of the operation, as well as possible Problems (P), and encourages questions of other team members (?). The StOP?-protocol draws attention to the team. Anticipating the occurrence of StOP?-protocols may support awareness of team processes and quality issues from the beginning and thus support other interventions such as the TTO; however, it also may signal an additional demand and contribute to a phenomenon akin to "checklist fatigue." We investigated if, and how, the introduction of the StOP?-protocol influenced TTO quality. Methods This was a prospective intervention study employing a pre-post design. In the visceral surgical departments of two university hospitals and one urban hospital the quality of 356 timeouts (out of 371 included operation) was assessed by external observers before (154) and after (202) the introduction of the StOP?-briefing. Timeout quality was rated in terms of timeout completeness (number of checklist items mentioned) and timeout quality (engagement, pace, social atmosphere, noise). Results As compared to the baseline, after the implementation of the StOP?-protocol, observed timeouts had higher completeness ratings (F = 8.69, p = 0.003) and were rated by observers as higher in engagement (F = 13.48, p < 0.001), less rushed (F = 14.85, p < 0.001), in a better social atmosphere (F = 5.83, p < 0.016) and less noisy (F = 5.35, p < 0.022). Conclusion Aspects of TTO are affected by the anticipation of StOP?-protocols. However, rather than harming the timeout goals by inducing "checklist fatigue," it increases completeness and quality of the team timeout.

Abstract
Alveolar echinococcosis is an endemic parasitosis in Switzerland. This pathology mainly infects the liver and develops similarly as a malignant tumor with its ability to spread into the hepatic parenchyma and its capacity of developing distant lesions via hematogenous dissemination. Treatment is based on complete surgical resection coupled with albendazole treatment. Recently, ex vivo liver resections with auto-transplantation have been shown to be feasible in case of end-stage alveolar echinococcosis. Moreover, new biomarkers such as programmed death-ligand 1 (PD-L1), a protein with immunomodulation property, have shown their potential impact on the treatment and follow-up of patients with alveolar echinococcosis.

Abstract
Acute cholecystitis is an inflammation of the gallbladder most often related to gallstones. The diagnostic and severity criteria are well described by the Tokyo criteria. Early laparoscopic cholecystectomy remains the treatment of choice. It can also be performed in elderly patients and in pregnant women during any trimester. For patients not eligible for surgery, percutaneous or echo-endoscopic gallbladder drainage (EUS-GBD) are effective treatment alternatives. The management of acute cholecystitis must therefore be adapted to each patient by carefully evaluating the risks and benefits associated with surgery.

Abstract
Whole-organ pancreas and islets transplantations are two therapeutic options to treat type 1 diabetic patients resistant to optimised medical treatment in whom severe complications develop. Selection of the best option for β-cell replacement depends on several factors such as kidney function, patient comorbidities, and treatment goals. For a patient with end-stage kidney disease, the treatment of choice is often a simultaneous transplant of the pancreas and kidney (SPK). However, it remains a major surgical procedure in patients with multiple comorbidities and therefore it is important to select those who will benefit from it. Additionally, in view of the organ shortage, new strategies to improve outcomes and reduce immune reactions have been developed, including dynamic organ perfusion technologies, pancreas bioengineering, and stem cell therapies. The purpose of this article is to review the indications, surgical techniques, outcomes, and future directions of whole-organ pancreas and islets transplantations.

Abstract
BACKGROUND The carcinogenic effect of arsenic (As) has been documented in lung, bladder and skin cancers but remains unclear for digestive cancers, although metabolic pathways of As and recent data suggest that it may be an important determinant in these malignancies as well. OBJECTIVE This study aimed to systematically review the available literature investigating the potential association between As and digestive cancers. METHODS An extensive search was conducted in Medline Ovid SP, Cochrane, PubMed, Embase.com, Cochrane Library Wiley, Web of Science and Google Scholar. Studies providing original data in humans, with As measurement and analysis of association with digestive cancers including esogastric cancers (esophagus and stomach), hepato-pancreatico-biliary (HPB) cancers (including biliary tract, liver and pancreas) and colorectal cancers were eligible. RESULTS A total of 35 studies were identified, 17 ecological, 13 case-control and 5 cohort studies. Associations between As and digestive cancers were reported for both risks of incidence and cancer-related mortality. Overall, 43% (3/7) and 48% (10/21) studies highlighted an association between As and the incidence or the mortality of digestive cancers, respectively. CONCLUSIONS A substantial proportion of studies exploring the potential link between As and digestive cancers suggested an association, particularly in HPB malignancies. These findings emphasize the need to further investigate this topic with dedicated and high-quality studies, as it may have an important impact, including for prevention strategies.

Abstract
BACKGROUND According to the Barcelona Clinic Liver Cancer (BCLC) staging system, liver resection (LR) is recommended for early-stage (BCLC-A) hepatocellular carcinoma (HCC) but not for intermediate-stage (BCLC-B). This study aimed to assess the outcomes of LR in these patients using a subclassification tumour burden score (TBS). METHODS All consecutive patients that underwent LR for BCLC-A and BCLC-B HCC between 01/2010 and 12/2020 in 4 tertiary referral centers were included. Clinical outcomes and overall survival (OS) were assessed in relation to TBS and BCLC stages. RESULTS Among 612 patients included, 562 were classified as BCLC-A and 50 as BCLC-B. The incidence of overall postoperative complications (56.0 vs 41.5%, p = 0.053) and mortality (0 vs 1.6%, p = 1.000) were similar between BCLC-A and BCLC-B patients. OS was significantly higher for BCLC A/low TBS than BCLC B/low TBS (p = 0.009), while patients with medium and high TBS had similar OS, irrespective of BCLC stage (respectively p = 0.103 and p = 0.343). CONCLUSIONS Patients with medium and high TBS had comparable OS and DFS, irrespective of BCLC A or B stage, and postoperative morbidity was comparable. These results highlight the need for refinement of the BCLC staging system, and LR could be considered for selected intermediate stage (BCLC-B) according to the tumour burden.

Abstract
OBJECTIVES Alveolar echinococcosis (AE) recurrence is one of the major stakes in patients undergoing surgery, the main curative treatment. Preliminary data demonstrated an effect of programmed death-ligand1 (PD-L1) inhibitors on AE proliferation in animals. The current study aimed to analyze the prognostic value of PD-L1 expression in tissue samples of patients with AE undergoing surgery. METHODS A cross-sectional study of patients operated for AE between 2002 and 2017 was performed. Patients with recurrence were matched 1: 2 with patients without recurrence. The matching criteria were PNM staging (P = hepatic localization of the parasite, N = extra-hepatic involvement of neighboring organs, and M = absence or presence of metastasis), resection status, preoperative albendazole treatment, and lesion size. PD-L1 immunohistochemistry staining was performed in surgical liver specimens. The expression of PD-L1 was assessed in immune cells. Disease-free survival was calculated using the Kaplan-Meier method. RESULTS Among 68 consecutive patients, eight patients with recurrence were matched to 16 patients without recurrence. PD-L1 was overexpressed in patients with recurrence (recurrence: PD-L1 <1%: one, PD-L1 ≥1%: seven; no recurrence: PD-L1 <1%: nine, PD-L1 ≥1%: seven, P = 0.040). Moreover, patients with lower PD-L1 expression (<1%) showed better median disease-free survival (120 months, 95% confidence interval 104-135 vs 74, 95% confidence interval 44-104, P = 0.050). CONCLUSION These findings highlight the proof of concept of PD-L1 in AE, but further data on its prognostic importance and the role of immune checkpoint blockade as a promising therapeutical strategy are needed.

Abstract
Gastric adenocarcinoma remains associated with a poor long-term survival, despite recent therapeutical advances. In most parts of the world where systematic screening programs do not exist, diagnosis is often made at advanced stages, affecting long-term prognosis. In recent years, there is increasing evidence that a large bundle of factors, ranging from the tumor microenvironment to patient ethnicity and variations in therapeutic strategy, play an important role in patient outcome. A more thorough understanding of these multi-faceted parameters is needed in order to provide a better assessment of long-term prognosis in these patients, which probably also require the refinement of current staging systems. This study aims to review existing knowledge on the clinical, biomolecular and treatment-related parameters that have some prognostic value in patients with gastric adenocarcinoma.

Abstract
BACKGROUND Incisional hernias (IH) constitute a complication after kidney transplant (KT). Patients may be particularly at risk because of comorbidities and immunosuppression. The study aim was to assess the incidence, risk factors, and treatment of IH in patients undergoing KT. METHODS This retrospective cohort study included consecutive patients who underwent KT between January 1998 and December 2018. Patient demographics, comorbidities, perioperative parameters, and IH repair characteristics were assessed. Postoperative outcomes included morbidity, mortality, need for reoperation, and length of stay (LOS). Patients who developed IH were compared with those who did not develop one. RESULTS Forty-seven patients (6.4%) developed an IH after a median delay of 14 months (IQR, 6-52 months) in 737 KTs. On uni- and multivariate analyses, body mass index (odds ratio [OR], 1.080; P = .020), pulmonary diseases (OR, 2.415; P = .012), postoperative lymphoceles (OR, 2.362; P = .018), and LOS (OR, 1.013; P = .044) were independent risk factors. Thirty-eight patients (81%) underwent operative IH repair, and 37 (97%) were treated with a mesh. The median LOS was 8 days (IQR, 6-11 days). Three patients (8%) developed surgical site infections, and 2 patients (5%) presented hematomas requiring surgical revision. After IH repair, 3 patients (8%) had a recurrence. CONCLUSIONS The incidence of IH after KT seems rather low. Overweight, pulmonary comorbidities, lymphoceles, and LOS were identified as independent risk factors. Strategies focusing on the modifiable patient-related risk factors and early detection and treatment of lymphoceles may help to decrease the risk of IH formation after KT.

Abstract
Gallbladder cancer (GBC) is one of the deadliest malignancy and treatment options are deplorably limited. Better strategies of prevention are urgently needed but knowledge on risk factors remains scarce. Recent data suggested that arsenic (As) may be involved in GBC carcinogenesis but the question remains debated. To date, there are no data on As measurement in GBC samples. This pilot study aimed to measure As concentrations in tissue samples from patients with GBC compared to non-cancerous gallbladder (NCGB). Included patients underwent cholecystectomy at Hospital Clinico Universidad de Chile, Santiago in Chile, a country with high As exposure, between 2001 and 2020. Tissue samples were preserved in formalin-fixed, paraffin-embedded blocks. Selected samples were retrieved, processed and submitted to inductively coupled plasma mass spectrometry (ICP-MS) to determine As concentrations. A total of 77 patients were included, including 35 GBC and 42 NCGB. The two groups were comparable, except for age (68 vs. 49 years, p < 0.001). Measured in 11 GBC and 38 NCGB, total As was detected in 5 GBC (14%) compared to 0 NCGB samples (p < 0.001). GBC group also showed higher median values of As compared to NCGB (p < 0.001). This pilot study provided a proof-of-concept to measure As concentrations in gallbladder samples and showed higher level of As in GBC samples compared to NCGB, paving the way for future studies aiming to investigate the impact of As on GBC, which may contribute to the prevention of this deadly disease.

Abstract
BACKGROUND The impact of hiatal hernia (HH) on oncologic outcomes of patients with esophageal adenocarcinoma (AC) remains unclear. The aim of this study was to assess the effect of pre-existing HH (≥3 cm) on histologic response after neoadjuvant treatment (NAT), overall (OS) and disease-free survival (DFS). METHODS All consecutive patients with oncological esophagectomy for AC from 2012 to 2018 in our center were eligible for assessment. Categorical variables were compared with the X2 or Fisher's test, continuous ones with the Mann-Whitney-U test, and survival with the Kaplan-Meier and log-rank test. RESULTS Overall, 101 patients were included; 33 (32.7%) had a pre-existing HH. There were no baseline differences between HH and non-HH patients. NAT was used in 81.8% HH and 80.9% non-HH patients (p = 0.910), most often chemoradiation (63.6% and 57.4% respectively, p = 0.423). Good response to NAT (TRG 1-2) was observed in 36.4% of HH versus 32.4% of non-HH patients (p = 0.297), whereas R0 resection was achieved in 90.9% versus 94.1% respectively (p = 0.551). Three-year OS was comparable for the two groups (52.4% in HH, 56.5% in non-HH patients, p = 0.765), as was 3-year DFS (32.7% for HH versus 45.6% for non-HH patients, p = 0.283). CONCLUSION HH ≥ 3 cm are common in patients with esophageal AC, concerning 32.7% of all patients in this series. However, its presence was neither associated with more advanced disease upon diagnosis, worse response to NAT, nor overall and disease-free survival. Therefore, such HH should not be considered as risk factor that negatively affects oncological outcome after multimodal treatment of esophageal AC.

Abstract
During 2022 a lot of efforts were developed to reduce health-costs by reducing complications and length of hospital stay. Same-day surgery is becoming the standard for all patients scheduled for elective surgery in CHUV. Outpatient colectomy also become a new standard. During 2022, endoscopic bariatric surgery became increasingly used. Not widely performed yet in Switzerland, these treatments deserve to be recognized and considered in various situations. Finally, 2022 saw a promising development of robotic surgery with the acquisition of Da Vinci and Dexter robots after allowing various high-precision surgical procedures.

Abstract
BACKGROUND Serum albumin has been shown to be predictive of complications after various gastrointestinal operations. The present study aimed to assess whether preoperative serum albumin and serum albumin drop on postoperative day 1 are associated with postoperative complications after pancreatic surgery. METHODS A single-center cross-sectional study was performed. All patients who underwent pancreatectomy between January 2010 and June 2019 and had preoperative serum albumin value and serum albumin value on postoperative day 1 were included. ΔAlb was defined as the difference between preoperative serum albumin and serum albumin on postoperative day 1. Binary logistic regressions were performed to determine independent predictors of postoperative complications. RESULTS A total of 185 patients were included. Pancreatoduodenectomies were performed in 133 cases, left pancreatectomies in 36, and other pancreas operations in 16. The preoperative serum albumin value was found to be an independent predictor of complications (OR 0.9, 95%CI 0.9-1.0, p = 0.041), whereas ΔAlb was not significantly associated with postoperative complications (OR 1.0, 95%CI 0.9-1.1, p = 0.787). The threshold of 44.5 g/L for preoperative albumin level was found to have the highest combined sensitivity and specificity based on the maximum Youden index. Patients with preoperative albumin < 44.5 g/L had a higher incidence of postoperative complications and higher median comprehensive complication index than patients with preoperative albumin ≥ 44.5 g/L. CONCLUSIONS This study highlighted that preoperative serum albumin is an independent predictor of postoperative complications after pancreas surgery.

Abstract
BACKGROUND Open mesh repair of incisional hernia is associated with different local complications, particularly bleeding and seroma formation. Traditionally, drains have been placed perioperatively to prevent these complications, despite the lack of scientific evidence or expert consensus. We formulated the hypothesis that the absence of drainage would reduce number of patients presenting collections or complications. The present study aimed to compare postoperative complication rates after open mesh repair for incisional hernia with or without prophylactic wound drainage. METHODS Prospective randomized study using standardized surgical technique and drain placement. The primary endpoint was the evaluation of residual fluid collection with ultrasound on postoperative day 30. Other complications, subdivided into medical and surgical, were analyzed as secondary endpoints. RESULTS There were 144 patients randomized (70 with drain, 74 without drain). No difference was identified between both groups for fluid collection at 30 days (60.3% vs. 62%, p = 0.844). However, less surgical complications were identified in the drain group (21.7% vs. 42.7%, p = 0.007), with a lower wound dehiscence rate (1.5% vs. 9.3%, p = 0.041). CONCLUSIONS Prophylactic drainage in open incisional hernia repair does not objectively reduce the rate of postoperative fluid collections. Therefore, our results do not support the use of routine drainage in incisional hernia repair. TRIAL REGISTRATION Trial registration on clinicaltrials.gov (NCT00478348).

Abstract
BACKGROUND Although Roux-en-Y gastric bypass (RYGB) is widely performed worldwide, its efficacy in patients with a body mass index (BMI) greater than 50 kg/m2 remains controversial. The aim of the present paper was to assess long-term (10 years or more) weight loss and metabolic results of RYGB in patients with superobesity (SO; BMI > 50 kg/m2), compared with patients with morbid obesity (MO; BMI 35-50 kg/m2). METHODS This study involved retrospective analysis of a prospectively followed cohort of adult patients operated on for a primary RYGB between 1999 and 2008. Long-term weight loss and metabolic parameters were compared between SO and MO patients, with a sex-specific subgroup analysis in SO patients. Multiple logistic regression assessed independent predictors of poor long-term weight loss. RESULTS Among the 957 included patients, 193 (20.2 per cent) were SO (mean BMI 55.3 kg/m2versus 43.3 kg/m2 in MO). Upon 10-year follow-up, which was complete in 86.3 per cent of patients, BMI remained higher in SO patients (mean 39.1 kg/m2versus 30.8 kg/m2, P < 0.001) although total bodyweight loss (per cent TBWL) was similar (28.3 per cent versus 28.8 per cent, P = 0.644). Male SO patients had a trend to higher 10-year per cent TBWL, while initial BMI greater than 50 kg/m2 and low 5-year per cent TBWL were independent predictors of long-term TBWL less than 20 per cent. Diabetes remission was observed in 39 per cent SO and 40.9 per cent MO patients (P = 0.335) at 10 years, and all patients had a significant lipid profile improvement. CONCLUSION Substantial improvement in co-morbidities was observed in all patients 10 years after RYGB. Total weight loss was similar in SO and MO patients, leaving SO patients with higher BMI. Suboptimal TBWL 5 years after surgery in SO, especially female patients, may warrant prompt reassessment to improve long-term outcomes.

Abstract
Background Lymph node ratio (LNR; positive/harvested lymph nodes) was identified as overall survival predictor in several cancers, including pancreatic adenocarcinoma. It remains unclear if LNR is predictive of overall survival in pancreatic adenocarcinoma patients staged pN2. This study assessed the prognostic overall survival role of LNR in pancreatic adenocarcinoma patients in relation with lymph node involvement. Methods A retrospective international study in six different centers (Europe and United States) was performed. Pancreatic adenocarcinoma patients who underwent pancreatoduodenectomy from 2000 to 2017 were included. Patients with neoadjuvant treatment, metastases, R2 resections, or missing data regarding nodal status were excluded. Survival curves were calculated using Kaplan-Meier method and compared using log-rank test. Multivariable Cox regressions were performed to find independent overall survival predictors adjusted for potential confounders. Results A total of 1,327 patients were included. Lymph node involvement (pN+) was found in 1,026 patients (77%), 561 pN1 (55%) and 465 pN2 (45%). Median LNR in pN+ patients was 0.214 [interquartile range (IQR): 0.105-0.364]. On multivariable analysis, LNR was the strongest overall survival predictor in the entire cohort [hazard ratio (HR) =5.5; 95% confidence interval (CI): 3.1-9.9; P<0.001] and pN+ patients (HR =3.8; 95% CI: 2.2-6.6; P<0.001). Median overall survival was better in patients with LNR <0.225 compared to patients with LNR ≥0.225 in the entire cohort and pN+ patients. Similar results were found in pN2 patients (worse overall survival when LNR ≥0.225). Conclusions LNR appeared as an important prognostic factor in patients undergoing surgery for pancreatic adenocarcinoma and permitted to stratify overall survival in pN2 patients. LNR should be routinely used in complement to tumor-node-metastasis (TNM) stage to better predict patient prognosis.

Abstract
Background: Locally advanced gastroesophageal junction adenocarcinoma (GEJ) is treated with either perioperative chemotherapy (CT) or preoperative radiochemotherapy (RCT) followed by surgery. The aim of this study was to compare pathologic response and long-term outcomes in junction adenocarcinoma treated with neoadjuvant RCT versus CT. Methods: All patients with locally advanced GEJ adenocarcinoma treated with neoadjuvant treatment (NAT) followed by surgery between 2009 and 2018 were retrospectively analyzed. Results: A total of 94 patients were included, 67 (71.2%) RCT and 27 (28.8%) CT. Complete pathologic response was more frequent in RCT patients (13.4% vs. 7.4%, p = 0.009) with a trend to better lymph node control (ypN0) (55.2% vs. 33.3%; p = 0.057). RCT offered no benefit in R0 resection (66.7% vs. 72.1% CT, p = 0.628) and was related to higher postoperative cardiovascular complications (35.8% vs. 11.1%; p = 0.017). Long-term overall and disease-free survival were similar (5-year OS 61.1% RCT vs. 75.7% CT, p = 0.259; 5-year DFS 33.5% RCT vs. 22.8% CT; p = 0.763). NAT type was neither independently associated with pathologic response nor long-term survival. Discussion: Patients with locally advanced GEJ adenocarcinoma treated with RCT had more postoperative cardiovascular complications but higher rates of complete pathologic response and a trend to superior locoregional lymph node control. This did not translate in a survival or recurrence benefit.

Abstract
Background Perioperative decrease of albumin (ΔAlb) appeared as a promising predictor of complications after digestive surgery, but its role after liver surgery remains unclear. This study aimed to analyze whether and how ΔAlb can be used to predict complications after liver surgery. Methods A bicentric retrospective analysis of patients undergoing liver surgery (2010–2016) was performed, following TRIPOD guidelines. The preoperative and postoperative difference of albumin was calculated on POD 0 and defined as ΔAlb. Patients with any missing variable were excluded. The primary endpoint was overall complications according to the Clavien classification. A multiparametric algorithm based on ΔAlb was generated to optimize prediction performance. Results A total of 110 patients were analyzed. At least one complication occurred in 66 (60%) patients. Patients with and without complication showed a ΔAlb of 15.8 vs. 9.5 g/L (p<0.001). Area under ROC curve (AUC) of ΔAlb was 0.75 (p<0.01.). The ΔAlb-based algorithm showed an AUC of 0.84 (p<0.01), significantly improving performance (p=0.03). Multivariable analysis identified ΔAlb as independent predictor of complications (HR, 1.12; 95% CI, 1.01–1.07; p = 0.002). Conclusions ΔAlb appeared as a promising predictor independently associated with the risk of complication after liver surgery. The study presents a novel decision-tree based on ΔAlb to anticipate complications.

Abstract
BackgroundGallbladder cancer (GBC) represents the most common biliary tract cancer. Prognosis remains poor with 5-year overall survival rates less than 5% in advanced stages. GBCs are diagnosed more frequently in women, supposedly due to endocrine factors.CaseA 35-year-old woman, diagnosed with a non-metastatic GBC in the 22nd week of gestation, underwent a complete surgical resection 5 weeks later. Adjuvant gemcitabine was administered without complications, temporarily discontinued in the 32nd week to allow childbirth. The patient was disease-free for more than 3 years with ongoing remission at the last visit in July 2022. During the follow-up period, the child had no developmental, cognitive, or other health issues.ConclusionMalignant tumors occur in about 0.1% of pregnant women, many are treated with chemotherapy. In oncology, the need to deliver optimal treatment in these patients represents a major concern. Both surgery and adjuvant chemotherapy of locally advanced GBC can be performed safely, with certain considerations, in the second trimester of pregnancy.

Abstract
This article addresses transparency in the current era of digital co-creation between healthcare professionals and patients. The concept of reasoned transparency is presented as a potential tool to guide the development of digital co-creation that is rapidly growing. The aim was to reflect on how doctors can apply transparency in their daily practice, following the shift from paternalistic to more collaborative relationships. On the one hand, our contribution indicates ways to take advantage of the existing digital tools to improve efficiency and increase patient trust, including the latest trend of artificial intelligence. On the other hand, this article identifies pitfalls of digitization and proposes reasoned transparency as remedy for the challenges rose by artificial intelligence. As a result, this perspective article tackles the issue of maintaining trustful and high-quality relationships between doctors and patients, increasingly challenged by the dissemination of online information and the pressures on healthcare professionals' accountability towards patients and the general public.

Abstract
INTRODUCTION Lymph node ratio (LNR) is an important prognostic factor of survival in patients with pancreatic ductal adenocarcinoma (PDAC). This study aimed to validate three LNR-based nomograms using an international cohort. MATERIALS AND METHODS Consecutive PDAC patients who underwent upfront pancreatoduodenectomy from six centers (Europe/USA) were collected (2000-2017). Patients with metastases, R2 resection, missing LNR data, and who died within 90 postoperative days were excluded. The updated Amsterdam nomogram, the nomogram by Pu et al., and the nomogram by Li et al. were selected. For the validation, calibration, discrimination capacity, and clinical utility were assessed. RESULTS After exclusion of 176 patients, 1'113 patients were included. Median overall survival (OS) of the cohort was 23 months (95% CI: 21-25). For the three nomograms, Kaplan-Meier curves showed significant OS diminution with increasing scores (p < 0.01). All nomograms showed good calibration (non-significant Hosmer-Lemeshow tests). For the Amsterdam nomogram, area under the ROC curve (AUROC) for 3-year OS was 0.64 and 0.67 for 5-year OS. Sensitivity and specificity for 3-year OS prediction were 65% and 59%. Regarding the nomogram by Pu et al., AUROC for 3- and 5-year OS were 0.66 and 0.70. Sensitivity and specificity for 3-year OS prediction were 68% and 53%. For the Li nomogram, AUROC for 3- and 5-year OS were 0.67 and 0.71, while sensitivity and specificity for 3-year OS prediction were 63% and 60%. CONCLUSION The three nomograms were validated using an international cohort. Those nomograms can be used in clinical practice to evaluate survival after pancreatoduodenectomy for PDAC.

Abstract
Liver transplant (LT) is the most favorable treatment option for patients with early stage hepatocellular carcinoma (HCC). Numerous attempts have been pursued to establish eligibility criteria and select HCC patients for LT, leading to various systems that essentially integrate clinico-morphological variables. Lacking of sufficient granularity to recapitulate the biological complexity of the disease, all these alternatives display substantial limitations and are thus undeniably imperfect. Liquid biopsy, defined as the molecular analysis of circulating analytes released by a cancer into the bloodstream, was revealed as an incomparable tool in the management of cancers, including HCC. It appears as an ideal candidate to refine selection criteria of LT in HCC. The present comprehensive review analyzed the available literature on this topic. Data in the field, however, remain scarce with only 17 studies. Although rare, these studies provided important and encouraging findings highlighting notable prognostic values and supporting the contribution of liquid biopsy in this specific clinical scenario. These results underpinned the critical and urgent need to intensify and accelerate research on liquid biopsy, in order to determine whether and how liquid biopsy may be integrated in the decision-making of LT in HCC.

Abstract
BACKGROUND The aim of this study was to evaluate feasibility and impact of an intraoperative surgical site infection prevention bundle for emergency appendectomy. METHODS Consecutive adult patients undergoing emergency appendectomy were prospectively included during a 10-year study period (2011-2020). The care bundle was implemented as of November 1, 2018, and focused on 4 intraoperative items (disinfection, antibiotic prophylaxis, induction temperature control >36.5°C, and intracavity lavage). The primary outcome was the compliance to bundle items. Thirty-day surgical site infections were assessed by the independent Swiss National SSI Surveillance Program (2011 to October 2018) and by an institutional audit (November 2018-2020). Independent risk factors for surgical site infection were identified through multinominal logistic regression analysis. RESULTS Of 1,901 patients, 449 (23.6%) were included after bundle implementation. Overall surgical site infection rate was 111 (5.8%). In 42 patients with surgical site infection (37.8%), antibiotic treatment alone was done, and additional surgical management was necessary in 31 patients (27.9%), computed tomography-guided drainage in 30 patients (27%), and bedside wound opening in 9 cases (8.1%). Overall compliance to the bundle was 79.9%. Overall surgical site infection rates were decreased after bundle implementation (17/449 [3.8%] vs 94/1,452 [6.5%], P = .038), mainly due to a decrease in superficial incisional infections (P = .014). Independent risk factors for surgical site infection were surgical duration ≥60 minutes (odds ratio: 1.66, P = .018), contamination class IV (odds ratio: 2.64, P < .001), and open or converted approach (odds ratio: 4.0, P < .001), and the bundle was an independent protective factor (odds ratio: 0.58, P = .048). CONCLUSION Implementation of an intraoperative surgical site infection prevention bundle was feasible and might have a beneficial impact on surgical site infection rates after emergency appendectomy.

Abstract
Background Malnutrition has been shown to be a risk factor for postoperative complications after pancreatoduodenectomy (PD). In addition, patients needing a PD, such as patients with pancreatic cancer or chronic pancreatitis, often are malnourished. The best route of postoperative nutrition after PD remains unknown. The aim of this randomized controlled trial is to evaluate if early postoperative enteral nutrition can decrease complications after PD compared to oral nutrition. Methods This multicenter, open-label, randomized controlled trial will include 128 patients undergoing PD with a nutritional risk screening ≥3. Patients will be randomized 1:1 using variable block randomization stratified by center to receive either early enteral nutrition (intervention group) or oral nutrition (control group) after PD. Patients in the intervention group will receive enteral nutrition since the first night of the operation (250 ml/12 h), and enteral nutrition will be increased daily if tolerated until 1000 ml/12 h. The primary outcome will be the Comprehensive Complication Index (CCI) at 90 days after PD. Discussion This study with its multicentric and randomized design will permit to establish if early postoperative enteral nutrition after PD improves postoperative outcomes compared to oral nutrition in malnourished patients.
