Short hospital stays after laparoscopic gastric surgery under an Enhanced Recovery After Surgery (ERAS) pathway: experience at a single center

Laparoscopic Appendectomy Combined with an "Antimicrobial-Free" Strategy for Acute Uncomplicated Appendicitis

Objective: To explore the efficacy and safety of enhanced recovery protocol (ERP) combined with laparoscopic appendectomy (LA) in the treatment of acute uncomplicated appendicitis (AUA) without antibiotics. Methods: In this study, a total of 160 patients with AUA who underwent LA between January 2018 and December 2021 were included and divided into the antibiotic group (n = 80) or the no-antibiotic group (n = 80). The patients in the antibiotic group received the ERP combined with antimicrobials during the perioperative period, while those in the no-antibiotic group only received the ERP during the perioperative period. The clinical data of these patients were collected to compare the inflammation level and stress state before and after surgery. In addition, the incidence of postoperative complications and the recovery speed of the patients were compared between groups. Results: There were no significant differences in the inflammation level and stress state before or after surgery, the incidence of postoperative complications or the recovery speed between the antibiotic group and the no-antibiotic group (P > .05). Conclusion: The use of ERP combined with LA as an antimicrobial-free treatment scheme in the perioperative period was found to be safe and effective for patients with AUA. Therefore, this approach is clinically valuable.

Adverse effects of long-term drain placement and the importance of direct aspiration: a retrospective cohort study

BACKGROUND

Long-term placement of prophylactic drains may result in retrograde infections.

AIM

To investigate the association between the timing of drain removal and clinical outcomes.

METHODS

This retrospective, single-centre cohort study evaluated 110 patients who underwent elective gastrointestinal or hepatopancreatobiliary surgery and developed subsequent organ/space surgical site infection (SSI) between 2016 and 2020. The difference between the culture-positive species of prophylactic drains and direct aspiration was evaluated; whether the prophylactic drains functioned effectively at the time of SSI diagnosis; and whether the empirical antibiotics administered before drainage were effective against all the detected bacteria. Finally, clinical outcomes were compared between early (i.e. cases wherein the prophylactic drain had already been removed or replaced at the time of SSI diagnosis) and late (removal after diagnosis) drain removal.

FINDINGS

The prophylactic drains functioned effectively in only 27 (25%) patients at the time of SSI diagnosis. Due to the results of direct aspiration cultures, 43% of patients required antibiotic escalation. The median time to drain removal or first replacement was seven postoperative days. The early removal group included 43 patients (39%). Compared with early removal, late removal resulted in a higher frequency of vancomycin use (7.0% vs 22.4%; P = 0.037).

CONCLUSION

Prolonged prophylactic drain placement is associated with complicated infections requiring vancomycin; therefore, the drains should be removed as soon as possible. Additionally, obtaining the cultures of direct aspiration should be actively considered, as escalation of antimicrobial therapy is often performed based on culture results.

D2 lymphadenectomy with complete mesogastrium excision vs. conventional D2 gastrectomy for advanced gastric cancer

Background:

The complete mesogastrium excision (CME) based on D2 radical gastrectomy is believed to significantly reduce the local-regional recurrence compared with D2 radical gastrectomy in advanced gastric cancer, and it is widely used in China. This study aimed to explore whether D2 + CME is superior to D2 on surgical outcomes during gastrectomy from Chinese data.

Methods:

Feasible studies comparing the D2 + CME (D2 + CME group) and D2 (D2 group) published up to March 2020 are searched from electronic databases. The data showing surgical and complication outcomes are extracted to be pooled and analyzed.

Results:

Fourteen records including 1352 patients were included. The D2 + CME group had a shorter mean operative time (weighted mean difference [WMD] = —16.72 min, 95% confidence interval [CI]: −26.56 to −6.87 min, P < 0.001), lower mean blood loss (WMD = −39.08 mL, 95% CI: −49.94 to −28.21 mL, P < 0.001), higher mean number of retrieved lymph nodes (WMD = 2.13, 95% CI: 0.58–3.67, P = 0.007), shorter time to first flatus (WMD = −0.31 d, 95% CI: −0.53 to − 0.10 d, P = 0.005), and postoperative hospital days (WMD = −1.09, 95% CI: −1.92 to −0.25, P = 0.010) than the D2 group. Subgroup analysis suggested that the advantages from the D2 + CME group were obvious in traditional open radical gastrectomy, proximal gastrectomy, and distal gastrectomy compared with D2 group. The evaluations of post-operative complications showed that the patients who underwent D2 + CME had a lower incidence of post-operative complications than the patients who underwent D2 surgery alone (relative risk [RR] = 0.65, 95% CI: 0.45–0.87, P = 0.003). The D2 radical gastrectomy plus CME improved 3-year overall survival (OS) (RR = 1.16, 95% CI: 1.02–1.32, P = 0.020) and lowered the local recurrence rate (RR = 0.51, 95% CI: 0.28–0.94, P = 0.030). The patients undergoing laparoscopic surgery or total gastrectomy had more significant advantages compared between D2 + CME and D2 groups in 3-year OS.

Conclusion:

The data from China show that D2 radical gastrectomy plus CME are reliable procedures and safety compared to D2 radical gastrectomy with faster recovery, lower risk, and better prognosis.

ERAS pathway for gastric cancer surgery: adherence, outcomes and prognostic factors for compliance in a Western centre

Adherence to an ERAS program guarantees an evidence-based approach for patient care, but the compliance to ERAS in patients undergoing surgery for gastric cancer in Western countries has not been clearly investigated. Our Institution has implemented an ERAS pathway (EP) for gastric surgery, composed of 24 items, since December 2016. We retrospectively analyzed the data of all consecutive patients undergoing surgery with curative intent for gastric cancer between January 2017 and December 2019 at our Institution, and were eligible for our EP. The primary endpoint was patients' compliance to the EP. Secondary endpoints were patients' adherence to each ERAS item and detection of variables associated with compliance failure. Seventy-three patients were included. Among these, 75.3% completed the EP, with a median number of items accomplished per patient of 21. Items with critical adherence were restrictive intraoperative fluid infusion (37%), avoidance of abdominal drain (14%), first clear liquid intake (67%), first solid food intake (48%). At univariate analysis age > 75 years, ASA > 2 and total gastrectomy were associated with failure to complete the EP. At multivariate analysis, ASA Score > 2 was the only preoperative factor associated with EP failure. Application of an ERAS program for malignant gastric surgery seems to be feasible with an acceptable completion rate in a tertiary referral Western centre. Preoperative factors, such as old age, advanced stage at diagnosis and neoadjuvant chemotherapy should not be considered as exclusion criteria for ERAS.

Recommendations from the ERAS® Society for standards for the development of enhanced recovery after surgery guidelines

BACKGROUND

ERAS® Society guidelines are holistic, multidisciplinary tools designed to improve outcomes after surgery. The enhanced recovery after surgery (ERAS) approach was initially developed for colorectal surgery and has been implemented successfully across a large number of settings, resulting in improved patient outcomes. As the ERAS approach is increasingly being adopted worldwide and new guidelines are being generated for new populations, there is a need to define an ERAS® Society guideline and the methodology that should be followed in its development.

METHODS

The ERAS® Society recommended approach for developing new guidelines is based on the creation of multidisciplinary guideline development groups responsible for defining topics, planning the literature search, and assessing the quality of the evidence.

RESULTS

Clear definitions for the elements of an ERAS guideline involve multimodal and multidisciplinary approaches impacting on multiple patient outcomes. Recommended methodology for guideline development follows a rigorous approach with systematic identification and evaluation of evidence, and consensus-based development of recommendations. Guidelines should then be evaluated and reviewed regularly to ensure that the best and most up-to-date evidence is used consistently to support surgical patients.

CONCLUSION

There is a need for a standardized, evidence-informed approach to both the development of new ERAS® Society guidelines, and the adaptation and revision of existing guidelines.

Enhanced recovery after surgery for gastric cancer (ERAS-GC): optimizing patient outcome

Significant advances were achieved, in last decades, in the management of surgical patients with gastric cancer. This has led to the concept of enhanced recovery after surgery (ERAS) with the objective of reducing the length of hospital stay, accelerating postoperative recovery and reducing the surgical stress. The ERAS protocols have many items, including the pre-operative patient education, early mobilization and feeding starting from the first postoperative day. This review aims to highlight possible advantages on postoperative functional recovery outcomes after gastrectomy in patients undergoing an ERAS program, current lack of evidences and future perspectives.

Effects of a stepwise, local patient-specific early oral feeding schedule after gastric cancer surgery: a single-center retrospective study from China

Nowadays, early oral feeding after gastrectomy has been gradually accepted and applied in the clinical practice, but there is still no specific uniform feeding regimen available which works best for patients in different regions with different races and eating habits. Aiming to establish an early oral feeding schedule suitable for local Chinese patients after gastric surgery, from May 2014 to May 2018, 87 gastric cancer patients undergoing various types of gastric resections were enrolled in an early feeding protocol and their clinical course was reviewed retrospectively. A stepwise, local patient-specific, early oral feeding schedule was proposed, implemented within an early recovery after surgery (ERAS) protocol and accessed in terms of its safety and tolerability. The primary surgical outcomes included: a median (interquartile range; IQR) postoperative hospital stay of 6 (3) days; 67 (77%) patients were well tolerant of this schedule from postoperative day (POD) 1 to POD 4; 20 (23%) patients had mild I/II grade complications (Clavien-Dindo classification); 3 (3%) patients had IIIB complications, zero cases of hospital mortality. Compared to similar studies in the past, our early oral feeding program is also safe and beneficial, and it can shorten the postoperative hospital stay without causing any increase in postoperative complications. In summary, our work herein reported the establishment of a detailed early oral feeding schedule embedded within an ERAS protocol which was found to be suitable for local Chinese patients after gastric surgery. Accordingly, this early oral feeding schedule is worth further research and promotion.

Use of inflammatory markers in the early detection of infectious complications after laparoscopic colorectal cancer surgery with the ERAS protocol

Introduction

Thanks to laparoscopy and enhanced recovery protocols (ERAS) it is possible to shorten hospitalization. Therefore, it seems reasonable to search for new early markers of infectious complications in order to select patients who are prone to development of complications.

Aim

To assess the usefulness of serum levels of C-reactive protein, interleukin-6 and procalcitonin as early indicators of infectious complications in patients after laparoscopic colorectal surgery with ERAS.

Material and methods

The prospective analysis included consecutive patients who underwent laparoscopic colorectal cancer resection. The following parameters were included in the analysis: C-reactive protein (CRP), interleukin 6 (IL-6) and procalcitonin measured on postoperative days (PODs) 1, 2, 3. Patients were divided into two groups: uncomplicated (group 1) and complicated (group 2). The difference in levels of the markers and the dynamics of changes observed in both groups were analyzed.

Results

Group 1 comprised 34 patients, and group 2 consisted of 17 patients. A significant increase of both absolute values and delta increments on all postoperative days was noted. ROC curve analysis showed that the best cut-off values indicating an infectious process were: CRP 129 mg/l on POD3 (92% sensitivity/80% specificity), IL-6 of 78 pg/ml on POD2 (91% sensitivity/97% specificity) and PCT 0.24 ng/ml on POD3 (93% sensitivity/68% specificity).

Conclusions

Our study showed that regular measurement of all analyzed markers in the early postoperative days may be beneficial in the detection of postoperative infectious complications. Further studies are needed to fully assess the role of routine biochemical measurements in the postoperative period after laparoscopic surgery with the ERAS protocol.

Enhanced recovery after surgery decreases intestinal recovery time and pain intensity in patients undergoing curative gastrectomy

Background

Enhanced recovery after surgery (ERAS) reduces postoperative stress, increases patient satisfaction, and reduces postoperative stay and cost. In this study, we evaluated the feasibility and effectiveness of ERAS protocols compared with conventional perioperative care group and their effect in gastric cancer patients undergoing gastrectomy.

Methods

A cohort of 366 patients were analyzed from a prospectively maintained database. The patients’ characteristics, tumor profile, surgical information data and postoperative complications were evaluated.

Results

Patients in the ERAS had a faster gastrointestinal function recovery and first flatus (3.26±0.64; P<0.001). Pain intensity of patients in the ERAS group was significantly lower than that of patients in the conventional care group on postoperative days 1 (2.33±0.98; P<0.001) and 3 (1.06±0.63; P<0.001). Postoperative hospital stays were significantly shorter in patients receiving ERAS program (6.66±3.36; P<0.001), than in those patients who received conventional perioperative care (9.02±2.61).

Conclusion

ERAS can reduce postoperative stress, enhance the recovery of the gut, reduce the pain intensity, and increase satisfaction in gastric cancer patient undergoing curative gastrectomy.

Outcome of Discharge Within 72 Hours of Robotic Gastrectomy Using Enhanced Recovery After Surgery Programs

AIMS

To evaluate the safety and outcome of discharge within 72 hours of a robotic gastrectomy together with enhanced recovery after surgery (ERAS) programs.

MATERIALS AND METHODS

In total, 108 consecutive patients received elective robotic gastrectomy for gastric cancer from April 2017 to September 2017. All patients attended ERAS programs, which do not routinely use nasogastric tubes but include early feeding, early ambulation, and standard discharge criteria, among other items.

RESULTS

The mean age was 58.7 ± 10.4 years old, and the mean body mass index was 22.9 ± 2.8 kg/m². The mean postoperative length of hospital stay was 5.6 ± 8.0 days, and 13 patients (12.0%) exhibited a complication within 30 days with no mortality. A total of 38 patients (35.2%) were discharged within 72 hours of surgery. Patients were grouped based on being discharged within or after 72 hours. The rate of complications was significantly lower in patients discharged within 72 hours than patients discharged after 72 hours (1/38, 2.6% versus 12/70, 17.1%, P = .028). Although patients discharged within 72 hours showed lower readmission numbers, this difference was not statistically significant (1/38, 2.6% versus 8/70, 11.4%, P = .116). One month after surgery, loss of weight, loss of total protein, loss of albumin, and loss of prealbumin in patients discharged within 72 hours were less than those of patients discharged after 72 hours.

CONCLUSION

Complication and readmission rates are low in patients discharged within 72 hours of robotic gastrectomy when ERAS programs and standard discharge criteria are used.

Patients' opinions on enhanced recovery after surgery perioperative care principles: a questionnaire study

Introduction

The enhanced recovery after surgery (ERAS) protocol relies on patients’ compliance and their awareness of its principles. Patients’ views on ERAS implementation have never been evaluated in Poland before.

Aim

To analyse patients’ opinions about this protocol.

Material and methods

One hundred forty consecutive patients undergoing elective laparoscopic procedures in which ERAS was implemented were asked to join the study. Out of them, 120 fulfilled the trial criteria and were surveyed once before and twice after surgery. A 22-question survey about the patient’s perception of ERAS principles was presented upon admission and on the day of discharge. A telephone follow-up was performed 2 weeks after discharge.

Results

Patients reported the need for being counselled by the anaesthetist/surgeon as the most important element of the protocol. Items such as being free of pain, being free of gastrointestinal symptoms, and being free of catheter were rated more highly preoperatively than on the day of discharge, whereas telephone check-up call, being able to drink and eat early after surgery, avoiding bowel preparation, avoiding preoperative fasting and reducing postoperative intravenous fluids were rated more highly on the day of discharge. Pain was still present in over half of patients two weeks after discharge. Only 4.76% of patients admitted in the telephone survey that they were afraid of early discharge. Shortening of the length of hospital stay thanks to ERAS was widely appreciated among all patients who did not find it necessary to spend a longer time in the hospital.

Conclusions

Polish patients approve the ERAS protocol as modern perioperative care. Patients emphasize the need for preoperative counselling and painless recovery.

Bariatric patients' nutritional status as a risk factor for postoperative complications, prolonged length of hospital stay and hospital readmission: A retrospective cohort study

BACKGROUND

The prevalence of obesity is growing worldwide. Malnutrition has been identified as a risk factor, leading to higher morbidity rate and prolonged length of hospital. So far there are no high quality data on the impact of malnutrition on length of hospital stay and morbidity regarding bariatric surgery. The aim of the study was to assess association between nutritional status and outcomes bariatric surgeries.

MATERIAL AND METHODS

The study was a prospective observational study.

INCLUSION CRITERIA

informed consent to participate in the study, age 18-65 years, meeting the eligibility criteria for bariatric treatment, qualification for laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y Gastric By-pass (LRYGB).

EXCLUSION CRITERIA

revision surgery, lack of necessary data. The primary endpoint was the evaluation of protein malnutrition risk prevalence. Secondary: influence of malnutrition risk patients' on treatment course and postoperative complications.

RESULTS

533 patients met inclusion criteria and were analyzed. 169 patients (32%) had qualitative risk of malnutrition. The body mass index (BMI) was significantly higher in malnutritioned group, p = 0.001. Albumins in malnutritioned group was 38 g/l (IQR 35-42), whereas in control group it was 41 g/l (IQR 39-43), p = 0.027. Lymphocyte count in malnutrition risk group and control group were 1.24 10'3/μl (IQR 1.1-1.37) and 1.94 10'3/μl (IQR1.7-2.3) respectively, p < 0.001. In linear regression model, a correlation between BMI and total number of lymphocytes was present, p < 0.001. Malnutrition risk did not affect the total morbidity rate. There was a difference in occurrence of postoperative nausea and vomiting, p = 0.033.

CONCLUSIONS

Higher BMI is associated with greater risk of malnutrition. Proper perioperative care may diminish the impact of malnutrition on adverse effects and length of stay (LOS).

Postoperative complications are associated with worse survival after laparoscopic surgery for non-metastatic colorectal cancer - interim analysis of 3-year overall survival

Introduction

Postoperative morbidity after colorectal resections for cancer remains a significant problem. Data on the influence of complications on survival after laparoscopic colorectal resection are still limited.

Aim

To analyze the impact of postoperative complications on long-term survival after radical laparoscopic resection for colorectal cancer.

Material and methods

Two hundred and sixty-five consecutive non-metastatic colorectal cancer patients undergoing laparoscopic colorectal resection for cancer were included in the analysis. The entire study group was divided into two subgroups based on the occurrence of postoperative complications. Group 1 included patients without postoperative morbidity and group 2 included patients with complications. The primary outcome was overall survival.

Results

Median follow-up was 45 (IQR: 34–55) months. Group 1 consisted of 187 (70.5%) patients and group 2 comprised 78 (29.5%) patients. Studied groups were comparable in terms of sex, age, body mass index, ASA class, cancer staging, localization of the tumor and operative time. Patients in group 1 had significantly better overall 3-year survival compared to those with complications (84.9% vs. 69.8%, p = 0.022). Kaplan-Meier curves showed significantly improved survival rates in patients without complications compared with complicated cases. The Cox proportional multivariate model showed that postoperative complications (HR = 2.83; 95% CI: 1.35–5.92; p = 0.0058) and AJCC III (HR = 3.17; 95% CI: 1.52–6.6; p = 0.0021) were independent predictors of worse survival after laparoscopic colorectal cancer surgery.

Conclusions

Our analysis of interim results after 3 years confirms that complications after laparoscopic colorectal cancer surgery have an impact on survival. For this reason, these patients should be carefully monitored after surgery aiming at early detection of recurrence.

Pancreatoduodenectomy for pancreatic head tumors in the elderly - Systematic review and meta-analysis

The age at which patients are undergoing pancreatoduodenectomy is increasing worldwide. The data on the outcome of this surgical procedure in the elderly is constantly expanding. This meta-analysis aims to assess the safety of pancreatoduodenectomy in elderly population, primarily focusing on morbidity and mortality. We searched the Medline, Embase and Cochrane databases to identify eligible studies. The most recent search was performed on 10th April 2017. Inclusion criteria were: (1) comparison of the characteristics and perioperative outcomes of older patients versus younger patients undergoing pancreatoduodenectomy; (2) objective evaluation of mortality or overall morbidity; and (3), publication in English. Exclusion criteria were: (1) a lack of comparative data; (2) a lack of primary outcomes or insufficient data to analyze; (3) a focus on procedures other than pancreatoduodenectomy; or (4), the impossibility of extraction of data specifically concerning pancreatoduodenectomy. Primary outcomes were overall morbidity and mortality. Secondary outcomes analyzed postoperative complications, R0 rate and length of hospital stay. 45 eligible studies were chosen, with a combined total of 21,295 patients. Older patients compared to younger patients had a higher risk of death (2.26% vs. 4.54%; RR: 2.23; 95% CI 1.74-2.87) and a higher complication rate (47.23% vs. 39.35%; RR: 1.17; 95% CI 1.12-1.24). There were no differences in pancreatic fistula occurrence (p = 0.27), bile leakage (p = 0.81), postoperative hemorrhage (p = 0.08), or R0 rate (p = 0.92). Our review confirms, that in the case of pancreatoduodenectomy, advanced age is a risk factor for increased non-surgical morbidity and, by extension, higher mortality.

Is the laparoscopic approach for rectal cancer superior to open surgery? A systematic review and meta-analysis on short-term surgical outcomes

Introduction

Over the past years the incidence of colorectal cancers has increased worldwide. Currently it is the most common gastrointestinal malignancy worldwide. The laparoscopic approach has become the gold standard for surgical treatment. However, a recently published meta-analysis showed no difference in short- and long-term oncological outcomes of laparoscopy for treating rectal cancer.

Aim

To assess current literature on short-term outcomes of rectal cancer treatment using laparoscopic surgery in comparison to the open approach.

Material and methods

We performed a systematic review and meta-analysis according to the PRISMA guidelines. The primary outcomes of interest were morbidity and short-term complications.

Results

We identified 4,328 potential references. In the end we included 13 randomized controlled trials (RCTs). We did not find any significant differences in terms of morbidity, haemorrhage, ureter injury, anastomotic leakage, mortality, intra-abdominal abscess or postoperative ileus. We found significant differences in the rate of surgical site infections, operative time, blood loss, length of hospital stay and time to first bowel movement.

Conclusions

This systematic review based on available RCTs confirms that laparoscopic rectal cancer surgery is associated with short-term outcomes comparable to the open approach. Moreover, in some aspects it provides better results (e.g. functional postoperative recovery, lower rate of surgical site infections (SSIs)). The quality of evidence is high; therefore in our opinion it is very unlikely that future trials will alter these results, and for this reason the laparoscopic approach can be considered the gold standard for the treatment of the majority of patients.

Current status of enhanced recovery after surgery (ERAS) protocol in gastrointestinal surgery

Enhanced Recovery After Surgery (ERAS) is an evidence-based paradigm shift in perioperative care, proven to lower both recovery time and postoperative complication rates. The role of ERAS in several surgical disciplines was reviewed. In colorectal surgery, ERAS protocol is currently well established as the best care. In gastric surgery, 2014 saw an establishment of ERAS protocol for gastrectomies with resulting meta-analysis showing ERAS effectiveness. ERAS has also been shown to be beneficial in liver surgery with many centers starting implementation. The advantages of ERAS in pancreatic surgery have been strongly established, but there is still a need for large-scale, multicenter randomized trials. Barriers to implementation were analyzed, with recent studies concluding that successful implementation requires a multidisciplinary team, a willingness to change and a clear understanding of the protocol. Additionally, the difficulty in accomplishing necessary compliance to all protocol items calls for new implementation strategies. ERAS success in different patient populations was analyzed, and it was found that in the elderly population, ERAS shortened the length of hospitalization and did not lead to a higher risk of postoperative complications or readmissions. ERAS utilization in the emergency setting is possible and effective; however, certain changes to the protocol may need to be adapted. Therefore, further research is needed. There remains insufficient evidence on whether ERAS actually improves patients’ course in the long term. However, since most centers started to implement ERAS protocol less than 5 years ago, more data are expected.

20 years' experience with laparoscopic splenectomy. Single center outcomes of a cohort study of 500 cases

BACKGROUND

Laparoscopic splenectomy (LS) has become the gold standard in elective spleen surgery. Although it is considered relatively safe, treatment results vary depending on a hospital's profile and the experience of the surgeon and center. We would like to present experience of a high-volume referral center with minimally invasive operations of the spleen.

MATERIAL AND METHODS

The retrospective cohort study included consecutive patients undergoing laparoscopic splenectomy in tertiary referral surgical center in 1998-2017. The entire study population (500 patients) was grouped into 5 cohorts of 100 consecutively operated patients. The primary endpoints were short-term outcomes of LS and secondary - analysis of indications and operative technique. The study group consisted of 316 women and 184 men, 46 (28-59) years old on average.

RESULTS

The most common indications for splenectomy were ITP (53%), lymphoma (21%) and spherocytosis (7%). Ratio of ITP versus other indications decreased significantly over time in favor of more difficult cases (<0.001). Average operative time of 100 (75-132.5) min and blood loss of 50 (20-150) ml were changing during study. Forty two patients required a blood transfusion with no difference among groups (p = 0.765). The use of postoperative drainage diminished from 100% to 7% (p < 0.001). The overall conversion rate (3%) and intraoperative complications (5%) did not differ among groups (p = 0.863 and 0.888). Perioperative morbidity was 8.6% and decreased significantly over time (OR: 0.78, 95%CI: 0.62-0.98). We noted mortality of 0.4% (1 patient in 1st and 1 in 5th group). Median LOS was 4 (1-16) days. A significant change in the operative technique from vessels first to hilar transection was noted.

CONCLUSION

Laparoscopic splenectomy seems to be a safe method associated with a low risk of perioperative complications and mortality. A careful reproducible operative technique, along with a well-trained team and standardized modern postoperative care is critical to improving outcomes.

Risk factors for prolonged hospitalization in patients undergoing laparoscopic adrenalectomy

Introduction

Even though laparoscopic adrenalectomy is currently a standard, there are important variations between different centres in short-term treatment results such as length of hospital stay (LOS) or morbidity.

Aim

To determine the factors affecting LOS in patients after laparoscopic transperitoneal lateral adrenalectomy (LTA).

Material and methods

The study enrolled 453 patients (173 men and 280 women, mean age 57 years) who underwent LTA between 2009 and 2017. Discharge from hospital after more than median hospital stay was considered as prolonged LOS. We evaluated factors that potentially may influence LOS (primary length of stay after surgery, excluding readmissions). Logistic regression models were used in univariate and corrected multivariate analyses, in order to identify the factors related to prolonged LOS.

Results

The median LOS after LTA in the studied group was 2 days. One hundred seventy-five (38.5%) patients required prolonged hospitalization. Univariate logistic regression showed that the following factors were related to prolonged LOS: presence of any comorbidity, cardiovascular disease, intraoperative complications, postoperative complications, day of the week of operation (surgery on Thursday or Friday), intraoperative blood loss, need for transfusion, hormonal activity, postoperative drainage, ASA (III–IV) and histological type – pheochromocytoma. Multivariate logistic regression showed that only complications (OR = 3.86; 95% CI: 1.84–8.04), day of the week of operation (Thursday or Friday) (OR = 4.85; 95% CI: 3.04–7.73), need for drainage (OR = 3.63; 95% CI: 1.55–8.52), and histological type – pheochromocytoma (OR = 2.48; 95% CI: 1.35–4.54) prolonged LOS.

Conclusions

Prolonged length of hospital stay following laparoscopic transperitoneal lateral adrenalectomy is strongly associated with the presence of postoperative complications, day of the week of operation (Thursday or Friday), need for drainage, and histological type – pheochromocytoma.

Changes in plasma albumin levels in early detection of infectious complications after laparoscopic colorectal cancer surgery with ERAS protocol

Background

Combination of laparoscopic approach with ERAS protocol in colorectal surgery allows for an early discharge. However there is a risk that some of the discharged patients are developing, asymptomatic at the time, infectious complications. This may lead to a delay in diagnostics and proper treatment introduction. We aimed to assess the usefulness of preoperative plasma albumin concentration and their changes as indicators of infectious complications in patients undergoing colorectal cancer surgery.

Methods

Prospective analysis included 105 consecutive patients who underwent laparoscopic colorectal cancer resection between August 2014 and September 2016. In all cases standardised 16-item perioperative care ERAS protocol was used (mean compliance > 85%). Patients with IBD, distant metastases, undergoing emergency or multivisceral resection were excluded. Blood samples were collected preoperatively and on POD 1, 2, 3. Plasma albumin concentration was measured. Patients were divided into two groups depending on the presence of infectious complications. We analysed the differences in the levels of albumin and the dynamics of changes.

Results

Group 1—82 not complicated patients, Group 2—23 patients with at least one infectious complication. Preoperatively, there were no significant differences in the levels of serum albumin between those groups (Group 1—38.7 ± 4.9 g/l; Group 2—37.7 ± 5.0 g/l). In postoperative period, decrease was observed in both (POD 1: Group 1—36.5 ± 4.2 g/l, Group 2—34.7 ± 4.2 g/l, p = 0.07; POD 2: Group 1—36.2 ± 4.1 g/l, Group 2—32.6 ± 5.6 g/l, p = 0.01; POD 3: Group 1—36.0 ± 4.4 g/l, Group 2—30.9 ± 3.5 g/l, p = 0.01). The decrease was significantly greater in Group 2 on POD 2 and 3.

Conclusions

We showed that a regular measurement of albumin in the early postoperative days may be beneficial in the detection of postoperative infectious complications. Although changes in albumins are observed early after surgery, this parameter is relatively unspecific.

The impact of fast track protocols in upper gastrointestinal surgery: A meta-analysis of observational studies

BACKGROUND

Fast track surgery has been implemented in colorectal procedures during the last decade and is accompanied by significant improvement in patient outcomes during the early postoperative period. However, to date, its adoption in upper gastrointestinal surgery remains a matter of debate. In this context, we aimed to summarize the existing evidence in the international literature.

MATERIALS AND METHODS

We searched Medline, Scopus, ClinicalTrials.gov and Cochrane Central Register databases for published randomized controlled trials. The meta-analysis was performed with the RevMan 5.3.5 software.

MAIN FINDINGS

Thirty studies were finally included in the present meta-analysis. The post-operative morbidity was not influenced by the implementation of fast track surgery (FTS) (OR 0.84, 95% CI 0.64-1.09). However, in cases treated with laparoscopic surgery fast track surgery seemed to reduce morbidity by 50% (p = .006). The overall mortality of patients was low in the majority of included studies and was not influenced by fast track surgery (OR 1.12, 95% CI 0.50-2.52). The duration of postoperative hospitalization was significantly reduced with the adoption of FTS (MD -2.24, 95% CI -2.63 to -1.85 days). Concurrently, the overall cost was significantly reduced in cases treated with FTS (MD -982.30, 95% CI -1367.68 to -596.91 U.S dollars).

CONCLUSION

According to the findings of our meta-analysis suggest that FTS seems to be safe in patients undergoing upper gastrointestinal surgery and reduce both the days of postoperative hospitalization and the overall cost. This observation should be taken into account in future recommendations to enhance the implementation of FTS protocols in current clinical practice.

Primary tumor resection in stage IV unresectable colorectal cancer: what has changed?

Most current guidelines do not recommend primary tumor resection in stage IV unresectable colorectal cancer. Rapid chemotherapy development over the last decade has substantially changed the decision making. However, results of recently published trials and meta-analyses suggest that primary tumor resection may in fact be beneficial, principally in terms of prolonged survival. Additional factors, such as use of minimally invasive approach or protocols of enhanced recovery after surgery, affect clinical outcomes as well, but are often neglected when discussing the state of the art in this area. There are still no randomized studies determining the legitimacy of upfront surgery in asymptomatic patients. Also, quality of life also plays an important role in choosing appropriate treatment. Having said that, there is no data that would prove whether primary tumor resection has an advantage on that issue. With all the uncertainty, currently decision making in unresectable stage IV colorectal cancer is primarily up to clinicians' knowledge, common sense and patients' preferences.

Semi-end-to-end esophagojejunostomy after laparoscopy-assisted total gastrectomy better reduces stricture and leakage than the conventional end-to-side procedure: A retrospective study

BACKGROUND AND OBJECTIVE

Laparoscopy-assisted total gastrectomy (LATG) has not gained popularity due to the technical difficulty of esophagojejunostomy (EJ) and the high incidence of EJ-related complications. Herein, we compared two types of EJ for Roux-en-Y reconstruction to determine whether semi-end-to-end (SETE) EJ is more convenient than the end-to-side (ETS) procedure and is capable of reducing stricture and leakage.

METHODS

A total of 268 patients who underwent LATG with Roux-en-Y reconstruction were included in this study. Two types of EJ were applied for LATG: conventional ETS EJ and SETE EJ. The surgical outcomes and postoperative complications were compared.

RESULTS

The mean reconstruction time in the SETE group was shorter than that in the ETS group (41.6 ± 8.0 min vs 51.3 ± 9.2 min, P = 0.000). The incidences of total EJ-related complications, EJ leakage, and EJ stricture in the SETE group and ETS group were 1.1% (1/92) and 10.2% (18/176), 1.1% (1/92) and 4.0% (7/176), and 0 and 6.2% (11/176), respectively. The incidence of total EJ-related complications in the SETE group was lower than that of the ETS group (P = 0.006), and the incidence of EJ stricture in the SETE group was lower than that of the ETS group (P = 0.034).

CONCLUSIONS

SETE EJ is more convenient than the conventional ETS procedure and is associated with a shorter reconstruction time and a lower incidence of EJ stricture and leakage.

Decreased length of stay and earlier oral feeding associated with standardized postoperative clinical care for total gastrectomies at a cancer center

BACKGROUND

Standardization of postoperative care has been shown to decrease postoperative length of stay.

METHODS

In June 2009, we standardized postoperative care for all gastrectomies at our institution. Four years' worth of total gastrectomies (2 years prior to standardization and 2 years after standardization) were reviewed to determine the effect of standardization on postoperative care, length of stay, complications, and readmissions.

RESULTS

Between June 2007 and July 2011, 99 patients underwent curative intent open total gastrectomy: 51 patients prior to standardization, and 48 patients poststandardization. Patients were predominantly male (70%); median age was 63; and median body mass index was 26. Standardization of postoperative care was associated with a decrease in median time to beginning both clear liquids and a postgastrectomy diet, earlier removal of epidural catheters, earlier use of oral pain medication, less time receiving intravenous fluids, and decreased length of stay (all P < .01). Groups showed no differences in complication rates, complication severity, diet intolerance, return to our Urgent Care Center, or readmission.

CONCLUSION

Institution of standardized postoperative orders for total gastrectomy was associated with a significantly decreased length of stay and earlier oral feeding without increasing postoperative complications, early postoperative outpatient visits, or readmissions.

Enhanced recovery program is safe and improves postoperative insulin resistance in gastrectomy

AIM: To assess the safety of enhanced recovery after surgery (ERAS) program in gastrectomy and influences on nutrition state and insulin-resistance.

METHODS: Our ERAS program involved shortening the fasting periods and preoperative carbohydrate loading. Eighty gastrectomy patients were randomly assigned to either the conventional group (CG) or ERAS group (EG). We assessed the clinical characteristics and postoperative outcomes prospectively. The primary endpoint was noninferiority in timely discharge from the hospital within 12 d. Secondary endpoints were the incidence of aspiration at anesthesia induction, incidence of postoperative complications, health related quality of life (HRQOL) using the SF8 Health Survey questionnaire, nutrition state [e.g., albumin, transthyretin (TTR), retinal-binding protein (RBP), and transferrin (Tf)], the homeostasis model assessment-insulin resistance (HOMA-R) index, postoperative urine volume, postoperative weight change, and postoperative oral intake.

RESULTS: The ERAS program was noninferior to the conventional program in achieving discharge from the hospital within 12 d (95.0% vs 92.5% respectively; 95%CI: -10.0%-16.0%). There was no significant difference in postoperative morbidity between the two groups. Adverse events such as vomiting and aspiration associated with the induction of general anesthesia were not observed. There were no significant differences with respect to postoperative urine volume, weight change, and oral intake between the two groups. EG patients with preoperative HOMA-R scores above 2.5 experienced significant attenuation of their HOMA-R scores on postoperative day 1 compared to CG patients (P = 0.014). There were no significant differences with respect to rapid turnover proteins (TTR, RBP and Tf) or HRQOL scores using the SF8 method.

CONCLUSION: Applying the ERAS program to patients who undergo gastrectomy is safe, and improves insulin resistance with no deterioration in QOL.

Cost minimization analysis of laparoscopic surgery for colorectal cancer within the enhanced recovery after surgery (ERAS) protocol: a single-centre, case-matched study

Introduction

The goal of modern medical treatment is to provide high quality medical care in a cost-effective environment.

Aim

To assess the cost-effectiveness of laparoscopic colorectal surgery combined with the enhanced recovery after surgery protocol (ERP) in Poland.

Material and methods

We designed a single-centre, case-matched study. Economic and clinical data were collected in 3 groups of patients (33 patients in each group): group 1 – patients undergoing laparoscopy with ERP; group 2 – laparoscopy without ERP; group 3 – open resection without ERP. An independent administrative officer, not involved in the treatment process, matched patients for age, sex and type of resection. Primary outcome was cost analysis. It was carried out incorporating institutional costs: hospital bed stay, anaesthesia, surgical procedure and equipment, drugs and complications. Secondary outcomes were length of stay (LOS), readmission and complication rate.

Results

Cost of laparoscopic procedure alone was significantly more expensive than open resection. However, implementation of the ERAS protocol reduced additional costs. Total cost per patient in group 1 was significantly lower than in groups 2 and 3 (EUR 1826 vs. EUR 2355.3 vs. EUR 2459.5, p < 0.0001). Median LOS was 3, 6 and 9 days in groups 1, 2 and 3 respectively (p < 0.001). Postoperative complications were noted in 5 (15.2%), 6 (18.2%) and 13 (39.4%) patients in groups 1, 2, 3 respectively (p = 0.0435).

Conclusions

In a low medical care expenditure country, minimally invasive surgery combined with ERP can be a safe and a cost-effective alternative to open surgery with traditional perioperative care.

Predictive value of drain amylase content for peripancreatic inflammatory fluid collections after laparoscopic (assisted) distal gastrectomy

BACKGROUND

Laparoscopic (assisted) distal gastrectomy (LDG) with radical lymphadenectomy for gastric cancer has been widely conducted, particularly in the Far East. Peripancreatic inflammatory fluid collection (PIFC) is a serious and frequent postoperative complication after LDG for gastric cancer. The aim of this study was to evaluate the diagnostic performance of drain amylase content (D-AMY) for clinically relevant PIFC after LDG.

METHODS

Two hundred and sixty-four patients who underwent LDG with prophylactic drains were enrolled. The predictive value of D-AMY on postoperative day (POD) 1 and POD 3 in the diagnosis of PIFC was evaluated.

RESULTS

Twenty (7.6 %) patients experienced postoperative PIFC. Area under the curve in terms of receiver operating characteristics curve analysis of D-AMY on POD 1 was 0.801, and the optimal cutoff value for prediction of PIFC was 904 IU/l, with 98.2 % negative predictive value. Another cutoff was proposed as 4078 IU/l, with 92.2 % specificity. Multivariable analyses identified D-AMY on POD 1 ≥900 and ≥4000 IU/l as independent diagnostic factors for PIFC. Among patients at high risk of PIFC (D-AMY on POD 1 ≥900 IU/l), those who on POD 3 retained D-AMY value in excess of 31.2 % of the D-AMY value on POD 1 were more likely to experience PIFC compared with those with a pronounced decrease in D-AMY.

CONCLUSIONS

D-AMY on POD 1 serves as a predictive factor for clinically relevant PIFC after LDG. Time-dependent changes in D-AMY can also be used for determining management of drains in patients at high risk of PIFC.

Use of a clinical pathway in laparoscopic gastrectomy for gastric cancer

AIM: To evaluate the implementation of a clinical pathway and identify clinical factors affecting the clinical pathway for laparoscopic gastrectomy.

METHODS: A standardized clinical pathway for gastric cancer (GC) patients was developed in 2001 by the GC surgery team at the Asan Medical Center. We reviewed the collected data of 4800 consecutive patients treated using the clinical pathway following laparoscopic gastrectomy with lymph node dissection for GC involving intracorporeal and extracorporeal anastomosis. The patients were treated between August 2004 and October 2013 in a single institution. To evaluate the rate of completion and risk factors affecting dropout from the clinical pathway, we used a multivariate logistic regression analysis.

RESULTS: The overall completion rate of the clinical pathway for laparoscopic gastrectomy was 84.1% (n = 4038). In the comparison between groups of intracorporeal anastomosis and extracorporeal anastomosis patients, the completion rates were 83.88% (n = 1740) and 84.36% (n = 2071), respectively, showing no statistically significant difference. The main reasons for dropping out were postoperative complications (n = 463, 9.7%) and the need for patient observation (n = 299, 6.2%). Among the discharged patients treated using the clinical pathway, the number of patients who were readmitted within 30 d due to postoperative complications was 54 (1.1%). In a multivariate analysis, the intraoperative events (OR = 2.558) were the most predictable risk factors for dropping out of the clinical pathway. Additionally, being male (OR = 1.459), advanced age (OR = 1.727), total gastrectomy (OR = 2.444), combined operation (OR = 1.731), and ASA score (OR = 1.889) were significant risk factors affecting the dropout rate from the clinical pathway.

CONCLUSION: Laparoscopic gastrectomy appears to be a good indication for the application of a clinical pathway. For successful application, patients with risk factors should be managed carefully.

Enhanced recovery after surgery with laparoscopic radical gastrectomy for stomach carcinomas

AIM: To study the efficacy of the enhanced recovery after surgery (ERAS) program in laparoscopic radical gastrectomy for stomach carcinomas.

METHODS: From June 2010 to December 2012, 61 gastric cancer patients who underwent laparoscopic-assisted radical gastrectomy with D2 lymphadenectomy at First Hospital of Jilin University were enrolled in this randomized controlled trial. (Clinical Trials.gov, registration ID: NCT01955096). The subjects were divided into the ERAS program group and the conventional control group. The clinical characteristics, recovery variables, and complications of patients were analyzed.

RESULTS: The time to first ambulation, oral food intake, and time to defecation were significantly shorter in the ERAS group (n = 30), compared to the conventional group (n = 31; P = 0.04, 0.003, and 0.01, respectively). The postoperative hospital stay was less in the ERAS group (6.8 ± 1.1 d) compared to the conventional group (7.7 ± 1.1 d) (P = 0.002). There was no significant difference in postoperative complications between the ERAS (1/30) and conventional care groups (2/31) (P = 1.00). There were no readmissions or mortality during the 30-d follow-up period.

CONCLUSION: The ERAS program is associated with a shorter hospital stay in gastric cancer patients undergoing laparoscopic radical gastrectomy. The ERAS protocol is useful in the treatment of gastric cancer.
