Background: Multiquadrant procedures are technically more demanding than sequential operations. The new single port (SP) system allows to work in every abdominal quadrant maintaining an adequate triangulation without the need for changes in the port positioning., Methods: In February 2020, two patients underwent a robotic SP partial nephrectomy for malignancy combined with a cholecystectomy and a left inguinal hernia repair respectively., Results: Both procedures were successfully completed with one robotic docking and without the need for conversion. The operative time was 213 minutes for the right partial nephrectomy (126 min) with cholecystectomy (18 min), and 257 minutes for the left partial nephrectomy (161 min) with inguinal hernia repair (35 min). Estimated blood loss was 200 (150-250) mL, while the total warm ischemia time was 15 minutes for the right partial nephrectomy and 53 minutes for the left partial nephrectomy. There were no intraoperative complications or perioperative transfusions. The postoperative course was uneventful, and the postoperative hospital stay was 1 and 2 days. Both resections had free margins and the median tumor size was 2.5 (1.5-3.5) cm. Histopathology analysis revealed chronic cholecystitis and renal cell carcinomas with free margins and a median tumor size of 2.5 (1.5-3.5) cm. After a mean follow-up of 24 months, no surgical-related complications or recurrence were detected., Conclusions: The robotic SP approach facilitates the completion of combined surgical procedures in multiple abdominal quadrants through a single 25mm incision.

Background: The role of proximal diversion in patients undergoing sigmoid resection and primary anastomosis for diverticulitis with generalized peritonitis is unclear. The aim of this study was to compare the clinical outcomes of sigmoid resection and primary anastomosis and sigmoid resection and primary anastomosis with a proximal diversion in perforated diverticulitis with diffuse peritonitis., Method: A systematic literature search on sigmoid resection and primary anastomosis and sigmoid resection and primary anastomosis with proximal diversion for diverticulitis with diffuse peritonitis was conducted in the Medline and EMBASE databases. Randomized clinical trials and observational studies reporting the primary outcome of interest (30-day mortality) were included. Secondary outcomes were major morbidity, anastomotic leak, reoperation, stoma nonreversal rates, and length of hospital stay. A meta-analysis of proportions and linear regression models were used to assess the effect of each procedure on the different outcomes., Results: A total of 17 studies involving 544 patients (sigmoid resection and primary anastomosis: 287 versus sigmoid resection and primary anastomosis with proximal diversion: 257) were included. Thirty-day mortality (odds ratio 1.12, 95% confidence interval 0.53-2.40, P = .76), major morbidity (odds ratio 1.40, 95% confidence interval 0.80-2.44, P = .24), anastomotic leak (odds ratio 0.34, 95% confidence interval 0.099-1.20, P = .10), reoperation (odds ratio 0.49, 95% confidence interval 0.17-1.46, P = .20), and length of stay (sigmoid resection and primary anastomosis: 12.1 vs resection and primary anastomosis with diverting ileostomy: 15 days, P = .44) were similar between groups. The risk of definitive stoma was significantly lower after sigmoid resection and primary anastomosis (odds ratio 0.05, 95% confidence interval 0.006-0.35, P = .003)., Conclusion: Sigmoid resection and primary anastomosis with or without proximal diversion have similar postoperative outcomes in selected patients with diverticulitis and diffuse peritonitis. However, further randomized controlled trials are needed to confirm these results., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Despite the greater prevalence of obesity, African American (AA) adults represent a minority of bariatric surgery patients. The aim of this study was to determine variables associated with attrition among AA patients seeking bariatric surgery. We performed a retrospective analysis of a consecutive series of AA patients with obesity referred for surgery and who initiated the preoperative work-up as per insurance requirements. The sample was then divided between those undergoing surgery and those who did not receive surgery. The multivariable logistic regression analysis showed that male patients (OR 0.53 95% CI 0.28-0.98) and those with public insurance (OR 0.56, 95% CI 0.37 - 0.83) were significantly less likely to undergo surgery. The use of telehealth was strongly associated with receiving surgery (OR 3.53, 95% CI 2.36 - 5.29). Our results might help developing targeted strategies to reduce attrition rates among AA patients with obesity seeking bariatric surgery., (© 2023.

Length of stay after bariatric surgery has progressively shortened. Same-day discharge (SDD) has been reported for the 2 most common bariatric procedures, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). The aim of this study is to evaluate the safety and success of SDD following SG and RYGB. Systematic literature search on SDD after bariatric surgery was conducted in Medline, Cochrane library, Google Scholar, and Embase. SDD was defined as discharging the patient during the day of the bariatric operation, without an overnight stay. The primary outcomes of interest were successful SDD, readmission, and morbidity rates. The secondary endpoints included reoperation and mortality rates. A proportion meta-analysis was performed to assess the outcomes of interest. A total of 14 studies with 33,403 patients who underwent SDD SG (32,165) or RYGB (1238) were included in the qualitative synthesis. Seven studies with 5000 patients who underwent SDD SG were included in the quantitative analysis, and pooled proportions (PPs) were calculated for the outcomes of interest. The SDD success rate was 63%-100% (PP: 99%) after SG and 88%-98.1% after RYGB. The readmission rate ranged from .6% to 20.8% (PP: 4%) after SDD SG and 2.4%-4% after SDD RYGB. Overall morbidity, reoperation, and mortality were 1.1%-10% (PP:4%), .3%-2.1% (PP: 1%), and 0%-.1% (PP: 0%), respectively, for SDD SG, and 2.5%-4%,1.9%-2.5%, and 0%-.9%, respectively, for SDD RYGB. SDD after SG seems feasible and safe. The outcomes of SDDRYGB seem promising, but the evidenceis stilllimitedto draw definitive conclusions. Selection criteria and perioperative protocolsmust be standardized to adequately introduce this practice., (Copyright © 2023 American Society for Metabolic and Bariatric Surgery.

Background: The utilization of the robot for inguinal hernia repairs has increased in the past years. The new Da Vinci Single Port (SP) system provides the benefits of single-incision procedures and might overcome the technical difficulties of previous single-incision techniques. The aim of this study was to evaluate the safety and feasibility of the SP transabdominal preperitoneal inguinal hernia repair (SP-TAPP) and compare its outcomes to the robotic multiport technique (MP-TAPP)., Methods: A prospective cohort of patients who underwent a robotic SP-TAPP and MP-TAPP between 2012 and 2022 was analyzed. Primary endpoints were same-day discharge, morbidity, and inguinal recurrence rates. Secondary endpoints included conversion, operative time, port-site incisional hernia, and chronic pain., Results: MP-TAPP and SP-TAPP were performed in 378 (81.3%) and 87 (18.7%) patients, respectively. Demographics were similar between groups. There were no conversions or intraoperative complications. Mean operative (MP-TAPP: 93.2 vs. SP-TAPP: 78.1 min, p = 0.003) and recovery time (MP-TAPP: 160.8 vs SP-TAPP: 112.6 min, p < 0.001) were significantly shorter in the SP group. Same-day discharge rate was higher (MP-TAPP: 86.5% vs. SP-TAPP: 97.7%, p = 0.001) after SP-TAPP; 30-day morbidity, readmissions, and chronic pain rates were similar between groups. After a mean follow-up of 30.6 months for MP-TAPP and 13.3 months for SP-TAPP, inguinal hernia recurrence and port-site incisional rates were similar between groups., Conclusion: Robotic SP-TAPP is safe and feasible. When compared to MP-TAPP, it showed similar postoperative morbidity, higher same-day discharge rates, and a quicker postoperative recovery. Further studies are needed to confirm the benefits of the SP platform., (© 2022. The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.)

Major bile duct injuries (BDIs) may require complex surgical repairs that are usually performed with a conventional open approach. This study aims to analyze current evidence concerning the safety and the outcomes of the minimally invasive (MI) approach for biliary anastomosis in post-cholecystectomy BDIs. A systematic search of MEDLINE, Embase, and Web-Of-Science indexed studies involving MI (laparoscopic or robotic) biliary anastomosis in patients with iatrogenic BDIs was performed. The quality of the studies was assessed using the MINORS criteria. A total of 13 studies involving 198 patients were included. One hundred and twenty-five patients (63.1%) underwent a laparoscopic biliary anastomosis, while 73 (36.1%) received an analogue robotic procedure. All the included BDIs were types D and E (E1-E5). The mean OT varied between 190 and 330 (mean = 227) minutes. Ten studies reported the mean intraoperative blood loss that ranged between 50 and 252 (mean = 135.9) mL. No conversions occurred in the robotic series, while four patients required conversion to open surgery among the laparoscopic ones. The mean length of postoperative hospital stay was 6.3 days. The reported overall morbidity was similar among the robotic and laparoscopic series. During the follow-up period, no surgery-related mortality occurred. A growing number of referral centers are showing the safety and feasibility of the MI approach for biliary anastomosis in patients with major BDIs. Further prospective comparative studies are needed to draw more definitive conclusions., (© 2022. Italian Society of Surgery (SIC).)

Chronic pancreatitis is a benign inflammatory disorder, which can lead to severe and persistent symptoms. Patients with recurrent episodes of abdominal pain often require endoscopic treatments, which are frequently associated with inadequate symptom relief. In selected patients, surgical treatment allows for a greater long-term pain reduction.As one of the first teams reporting this approach, we present a didactical video with a stepwise technique to perform a robotic Puestow procedure.This technical report details a robotic approach to complete a latero-lateral pancreatojejunostomy in patients with symptomatic chronic pancreatitis with dilated main pancreatic duct.The robotic approach has shown to be an effective treatment with postoperative relief of ductal hypertension and successful long-term outcomes in patients with symptomatic chronic pancreatitis. A properly executed operation following precise surgical steps is critical for the success of the procedure., (© 2022. Italian Society of Surgery (SIC).)

Background: We aim to analyse the safety and feasibility of the DaVinci Single Port (SP) platform in general surgery., Methods: A prospective series of robotic SP transabdominal pre-peritoneal inguinal hernia repairs (SP-TAPP) and cholecystectomies (SP-C) (off-label) were analysed. Primary endpoints were safety and feasibility defined by the need for conversion and incidence of perioperative complications., Results: A total of 225 SP procedures were performed; 84 (37.3%) SP-TAPP (70 unilateral, 7 bilateral), and 141 (62.7%) SP-C. There were no conversions or additional ports placed. Mean console time was 17.6, 31.9, and 54 min for SP-C, unilateral, and bilateral SP-TAPP, respectively. There was no mortality, intraoperative or major postoperative complications. Mean LOS was 2.7 h for elective SP-TAPP and 2.3 h for SP-C., Conclusion: Robotic SP surgery is safe and feasible for two of the most performed general surgery operations. Further experience might allow expanding the applications of robotic single-incision surgery for other procedures., (© 2022 The Authors.

Purpose: Same-day discharge (SDD) after bariatric surgery is gaining popularity. We aimed to analyze the safety of SDD after Roux-en-Y gastric bypass (RYGB) and compare its outcomes to inpatients discharged on postoperative days 1-2., Materials and Methods: We performed a retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database for the period 2015-2020. Patients who underwent primary laparoscopic RYGB and were discharged the same day of the operation (SDD-RYGB) and inpatients discharged on postoperative days 1-2 (In-RYGB) were compared. Primary outcomes of interest were overall morbidity, serious morbidity, readmission, reoperation, intervention, and mortality rates., Results: A total of 167,188 patients were included; 2156 (1.3%) SDD-RYGB and 165,032 (98.7%) In-RYGB. Mean age (SDD-RYGB: 44.5 vs. In-RYGB: 44.6 years), proportion of females (SDD-RYGB: 81.4% vs. In-RYGB: 80.6%), and mean body mass index (SDD-RYGB: 45.8 vs. In-RYGB: 45.9 kg/m 2 ) were similar between groups. Overall morbidity (SDD-RYGB: 11.3% vs. In-RYGB: 10.2%; OR: 1.2, p = 0.08), serious morbidity (SDD-RYGB: 3.1% vs. In-RYGB: 3%; OR: 1.03, p = 0.81), reoperation (SDD-RYGB: 1.4% vs. In-RYGB: 1.2%; OR: 1.16, p = 0.42), readmission (SDD-RYGB: 4.8% vs. In-RYGB: 4.8%; OR: 1.01, p = 0.89), and mortality (SDD-RYGB: 0.04% vs. In-RYGB: 0.09%; OR: 0.53, p = 0.53) were comparable between groups. SDD-RYGB had lower risk of 30-day interventions (SDD-RYGB: 1.1% vs. In-RYGB: 1.6%; OR: 0.64, p = 0.04) compared to In-RYGB., Conclusion: Same-day discharge after RYGB seems to be safe and has comparable outcomes to admitted patients. Standardized patient selection criteria and perioperative management protocols are needed to further increase the safety of this practice., (© 2022.

Introduction: To date, no anti-reflux operations have been reported with the new da Vinci Single-Port (single port (SP)) robotic platform. We aimed to describe this novel surgical approach and evaluate its safety and feasibility., Methods: All robotic SP operations were performed under an Institutional Review Board approved protocol., Results: Two patients underwent robotic SP anti-reflux surgery through a single incision of 2.7 cm (one Nissen-fundoplication and one re-Redo Nissen-fundoplication). The mean docking-time was 2.5 (2-3) minutes and mean console-time was 147 (119-155) minutes. No additional ports were needed, and no intraoperative complications occurred. Patients tolerated a soft diet on postoperative day 1 and were discharged on POD-2 and 3., Conclusion: Robotic SP anti-reflux surgery appears to be safe and feasible. This platform offers similar advantages to the multiport robotic surgery, while adding lower invasiveness and an improved cosmesis. Further studies are needed to confirm our results and evaluate long-term outcomes of this surgical approach., (© 2022 The Authors.

Background: The demand for revisional bariatric surgery has increased, and bariatric conversions (BC) to a different procedure represent most of the revisional cases. The 2020 Metabolic and Bariatric Surgery Accreditfnation and Quality Improvement Program (MBSAQIP) database was expanded to include additional variables on BC. This study aims to analyze the indications and outcomes of BC., Methods: A retrospective analysis of the 2020 MBSAQIP database was performed. Patients who underwent BC were included in the analysis. Index procedures, rates, and indications for BC of the different bariatric operations were described. Outcomes of the most frequent BC were analyzed., Results: A total of 168,548 bariatric surgeries were done; 20,387 (12.1%) were revisional, and from those 15,031 (73.7%) were BC. The most converted index operations were sleeve gastrectomy (SG) (49.3%) and adjustable gastric banding (AGB) (45.9%). The most frequent conversions were SG to Roux-en-Y gastric bypass (RYGB) (40.3%) for gastroesophageal reflux disease (GERD) (54.2%) and weight loss failure (WLF) (35.8%), AGB to SG (27%) or RYGB (16.2%) for WLF (67% and 61.3%, respectively), and SG to biliopancreatic diversion with duodenal switch (3.2%) or single anastomosis duodeno-ileal bypass (2%) for WLF (91.2% and 92.4%, respectively). Postoperative overall morbidity, serious morbidity, reoperation, and mortality rates ranged from 5.3 to 20.8%, 2.3 to 19.2%, 1.5 to 10%, and 0 to 0.8%, respectively., Conclusions: BC represents the most frequent revisional bariatric procedure. GERD and WLF are the main causes for BC. Further research is needed to define the ideal BC according to the index procedure and indication., (© 2022.

Despite being equally affected by obesity, females represent the vast majority of obese patients undergoing bariatric surgery. We aimed to identify potential gender disparities among African American (AA) patients seeking bariatric surgery at our institution. Demographics, presence of comorbidities, socio-economic variables, type of consultation, and attrition rates were compared among male and female patients. A total of 710 patients were referred for bariatric surgery; 468 (65.9%) were AA: 68 (14.5%) male and 400 (85.5%) female. Male patients were older, were more frequently married, and had higher prevalence of obesity-related comorbidities, as compared to female patients. Male patients showed significantly higher high school graduation rates, higher income, and longer distance to the hospital. The use of telehealth was similar in both groups. Male patients had significantly higher attrition rates (73.5% vs. 56.7%, p=0.009). Strategies to better promote and increase access to bariatric surgery to male patients should be prioritized., (© 2022.

Purpose: Stump appendicitis (SA) is a rare long-term complication after laparoscopic appendectomy (LA) that can be associated with high morbidity due to delayed diagnosis. We aimed to determine the incidence, risk factors, diagnosis, and management of SA by reviewing our large cohort of LA and performing a systematic review of the literature., Methods: We retrospectively reviewed data of all patients who developed SA after LA between 2006 and 2020. Demographics, peri-operative variables, and postoperative outcomes were analyzed. A systematic review of the PubMed/MEDLINE, Embase and GoogleScholar bibliographic databases was also performed to identify publications regarding SA following LA., Results: A total of 2,019 patients underwent LA; 5 (0.25%) developed SA after a median of 292 days. The most common symptom at presentation was right lower quadrant pain. Four SA (80%) occurred in patients with a history of complicated appendicitis at index operation. All patients were diagnosed with computed tomography and underwent completion stump appendectomy by laparoscopy. No postoperative complications were recorded. A total of 55 studies with 76 cases of SA after LA were identified in the systematic review. Most SA (98.7%) underwent surgery: 52% by laparoscopic approach and 36% through an open approach. Stump appendectomy was performed in 94.4% cases and an extended resection in 5.6%., Conclusion: Although SA is a rare complication after LA, a high index of clinical suspicious and imaging studies are key for early diagnosis and treatment. A laparoscopic resection of the inflamed appendiceal stump is feasible, safe, and highly effective. A minority of patients with severe cecum compromise may need extended resections or conversion to open surgery., (© 2021. Springer-Verlag GmbH Germany, part of Springer Nature.)

Background: Despite the high success rate associated with Heller myotomy in the treatment of primary achalasia, symptom persistence or relapse occurs in approximately 10-20% of patients. Unfortunately, the ideal treatment after failed myotomy is not well established yet. We present a didactical video with a stepwise technique to perform a robotic revisional procedure after failed Heller myotomy., Methods: In this report, each surgical step is thoroughly described and visually represented with useful technical tips that might help in improving surgical results of revisional Heller myotomy., Results: In patients with previous surgical myotomy, the robotic platform with its high-definition magnified view and EndoWrist instruments allow for a safe and precise redo surgical myotomy., Conclusions: Despite its improved surgical capabilities, the role of robotic redo Heller myotomy in the treatment algorithm of patients with recurrent symptoms after failed surgical myotomy should be further explored., (© 2022.

Laparoscopic sleeve gastrectomy is one of the most common bariatric surgical procedures. Despite being easier to perform than other bariatric procedures, it is not free of complications. Leaks are some of the most severe events, and are observed in around 0.5-6% of cases. Use of the near-infrared indocyanine green (ICG) perfusion test during sleeve gastrectomy seems to be promising. However, its application in sleeve gastrectomy is still in fieri. Similarly, ICG is not commonly used in Roux-en-Y gastric bypass. This report presents the main evidence from selected literature regarding the use of ICG during sleeve gastrectomy and Roux-en-Y gastric bypass, along with our remarks. It also provides intraoperative video clips and photographs showing the use of ICG in this surgical field.

Background: Centrally located pancreatic lesions are often treated with extended pancreaticoduodenectomy or distal pancreatectomy resulting in loss of healthy parenchyma and a high risk of diabetes and exocrine insufficiency. Robotic central pancreatectomy (RCP) is a parenchyma sparring alternative that has been shown safe and feasible [1,2]., Methods: In this article, we describe our operative technique and the perioperative outcomes of a series of RCP for low-grade or benign pancreatic tumors., Results: Six patients (5 female and 1 man) with a median age of 51.5 (44-68) years underwent a RCP for 2 serous cystadenomas, 2 mucinous cystic tumors, 1 neuroendocrine tumor, and 1 autoimmune pancreatitis. There were no conversions, intraoperative complications, or perioperative transfusions. Median operative time and was 240 (230-291) minutes and median blood loss was 100 (100-400) ml. The median hospital stay was 8 (5-27) days. There were no mortalities, reoperations, or readmissions. One patient developed a grade B pancreatic fistula which was successfully managed conservatively. All resections had free margins and the median tumor size was 2.5 (1.5-3.5) cm. After a mean follow-up of 46 months, no patients presented new-onset diabetes or exocrine insufficiency., Conclusions: RCP represents the least invasive option for both the patient and the pancreatic parenchyma. With a standardized technique, RCP results in low postoperative morbidity and excellent long-term pancreatic function. Although our results are excellent, POPF still represents the main complication of central pancreatectomy with an incidence ranging from 0 to 80% depending on multiple factors such as the surgeon, technique, and pancreatic texture., (Copyright © 2022 Elsevier Ltd.

Background: Indocyanine green (ICG) fluorescence imaging is an emerging technology that might help decreasing anastomotic leakage (AL) rates. The aim of this study was to determine the usefulness of ICG fluorescence imaging for the prevention of AL after minimally invasive esophagectomy with intrathoracic anastomosis., Methods: A systematic literature review of the MEDLINE and Cochrane databases was performed to identify all articles on totally minimally invasive Ivor Lewis esophagectomy. Studies were then divided into two groups based on the use or not of ICG for perfusion assessment. Primary outcome was anastomotic leak. Secondary outcomes included operative time, ICG-related adverse reactions, and mortality rate. A meta-analysis was conducted to estimate the overall weighted proportion and its 95% confidence interval (CI) for main outcomes., Results: A total of 3,171 patients were included for analysis: 381 (12%) with intraoperative ICG fluorescence imaging and 2,790 (88%) without ICG. Mean patients' age and proportion of males were similar between groups. Mean operative time was also similar between both groups (ICG: 354.8 vs. No-ICG: 354.1 minutes, P = 0.52). Mean ICG dose was 12 mg (5-21 mg). No ICG-related adverse reactions were reported. AL rate was 9% (95% CI, 5-17%) and 9% (95% CI, 7-12%) in the ICG and No-ICG groups, respectively. The risk of AL was similar between groups (odds ratio 0.85, 95% CI 0.53-1.28, P = 0.45). Mortality was 3% (95% CI, 1-9%) in patients with ICG and 2% (95% CI, 2-3%) in those without ICG. Median length of hospital stay was also similar between groups (ICG: 13.6 vs. No-ICG: 11.2 days, P = 0.29)., Conclusion: The use of ICG fluorescence imaging for perfusion assessment does not seem to reduce AL rates in patients undergoing minimally invasive esophagectomy with intrathoracic anastomosis., (© The Author(s) 2021.

Background: With the rising number of bariatric surgeries performed annually, there has also been an increase in revisional bariatric surgeries (RBS). The aim of this study is to evaluate the safety and postoperative outcomes of RBS performed with a minimally invasive approach., Methods: Retrospective analysis on a prospectively collected database of patients who underwent minimally invasive RBS between 2012 and 2019. Primary endpoints were conversion rate, major morbidity, mortality, and 30-day reoperation rate. Comparative analysis of laparoscopic adjustable gastric banding (LAGB) conversion to sleeve gastrectomy (SG) vs. conversion to Roux-en-Y gastric bypass (RYGB) was performed., Results: A total of 221 patients underwent minimally invasive RBS, 137 (62%) laparoscopically and 84 (38%) robotically. The most common RBS were LAGB to SG (59.3%) and LAGB to RYGB conversions (16.7%). The main indication was weight loss failure (88.7%). Conversion rate, major morbidity, and mortality were 0.9, 3.2, and 0.4%, respectively. Urgent reoperation was required in 3.2% of cases. Total weight loss at 1 and 2-years follow- were 14.3 and 17.3%, respectively. Comparative analysis of LAGB conversion to SG vs. RYGB showed similar major morbidity (SG: 2.3% vs. RYGB 0%, p = 1). Greater total weight loss was achieved in LAGB to RYGB conversions at 1-year (SG: 14.8% vs. RYGB 25.3%, p < 0.001)., Conclusions: Minimally invasive RBS can be performed safely in a broad patient population with low conversion and complication rates, and improved weight loss outcomes. LAGB to RYGB conversions are associated with greater weight loss. Further randomized trials are needed to draw more conclusive recommendations., Competing Interests: FB has an education agreement with intuitive. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Xie, Dreifuss, Schlottmann, Cubisino, Mangano, Vanetta, Baz, Valle, Bianco, Gangemi and Masrur.)

Background: Same-day discharge after sleeve gastrectomy (SG) is gaining popularity. We aimed to determine risk factors associated with readmission in patients who underwent same-day discharge SG., Methods: We performed a retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database for the period 2015-2018. Patients who underwent SG and were discharged the same day of the operation were included in the analysis. Multivariable logistic regression analysis was performed to determine risk factors for readmission., Results: A total of 466,270 SG were performed during the study period; 14,624 (3.1%) patients were discharged the same day and were included in the analysis. Mean age was 43.4 (14.7-80) years and 11,718 (80.1%) were female. Mean preoperative BMI was 43.7 ± 7.4 kg/m 2 . Mean operative time was 58.3 ± 32.4 min. Thirty-day reoperation, reintervention, and mortality rates were 0.7%, 0.7%, and 0.1%, respectively. Readmission rates were similar in same-day discharge and inpatient SG (2.9% vs. 3%, p = 0.5). Female sex (OR 1.52, 95% CI 1.15-2.00), preoperative gastroesophageal reflux disease (OR 1.33, 95% CI 1.08-1.64), renal insufficiency (OR 3.06, 95% CI 1.01-9.32), and intraoperative drain placement (OR 1.78, 95% CI 1.37-2.31) were independent risk factors for readmission following same-day discharge SG., Conclusions: Same-day discharge SG appears to be safe and is associated with low readmission rates. However, the identification of preoperative and intraoperative variables associated with higher risk of readmission might help defining safer and more effective same-day discharge protocols., (© 2022.

Bariatric surgery has been demonstrated to be effective in achieving significant weight loss and remission of obesity-related comorbidities. However, a percentage of patients fail to lose enough weight, regain weight, or experience postoperative complications, requiring additional interventions. Revisional bariatric surgeries (RBS) involve the wide spectrum of procedures that aim to treat complications of the index operation or achieve further weight loss. These are technically challenging procedures due to adhesions of the internal organs, reduced working space, and a distorted anatomy. Indications, timing, and type of operation for RBS are not standardized, and there is no consensus on the best surgical approach. Some authors claim a robotic platform could be advantageous in these types of procedures that are performed in reduced, deep operating fields, or those requiring precision and accuracy. This review examines the most current and representative literature on the outcomes of robot-assisted RBS. Included studies demonstrate the safety and feasibility of the robotic approach for RBS. However, long operative times and high costs remain major drawbacks of the device. Finally, if we consider that many centers have not yet completed the learning curve for robot-assisted RBS, the potential for improved outcomes seems promising.

Background: Minimally invasive resection of gastrointestinal stromal tumors (GIST) results in faster recovery and similar oncological safety when compared to conventional approach [1-3]. The new robotic Single Port platform (Da Vinci SP) could help decreasing invasiveness while overcoming technical limitations of previous single incision surgical approaches [4]., Methods: A 69-year-old male was treated for a 3 cm non-ulcerated GIST in the anterior wall of the proximal gastric body., Results: A robotic partial gastric resection was performed. The Da Vinci SP platform, which hosts three multi jointed, wristed instruments and a 3D HD articulating scope was used. The camera and instruments were introduced in the abdominal cavity through a 25 mm multichannel port. The lesion was identified in the lesser curvature at the level of the body, approximately 3 cm above the incisura. The gastric wall was resected en-bloc with the tumor using a combination of monopolar hook and bipolar forceps. The lesion was lifted using the third robotic arm and was not manipulated during the dissection. The gastric defect was closed with two running sutures of polydioxanone 3/0. Operative time was 82 minutes. Postoperative course was uneventful, and the patient was discharged home on postoperative day 2 with adequate pain control. Histopathology analysis found a 2.3 × 2 cm low grade GIST., Conclusions: Robotic SP partial gastrectomy is safe and feasible in patients with gastric GIST. The robotic SP approach might help expanding the indications of previous single incision techniques., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Introduction: Gallstone ileus is an uncommon complication of long-term cholelithiasis. Emergent operations for gallstone ileus are associated with high postoperative morbidity. When feasible, the minimally invasive approach might help to improve the postoperative outcomes., Presentation of Case: A 63-year-old female was admitted for abdominal pain and vomiting. Computed tomography (CT) scan showed a cholecystoduodenal fistula and a 5 × 3 cm gallstone in the jejunum causing obstruction. An emergent laparoscopy was performed, and a gallstone was found inside the jejunum 40 cm distal to the ligament of Treitz. The 5 cm gallstone was extracted through an antimesenteric enterotomy. The jejunum was then closed transversally using interrupted sutures. The postoperative course was uneventful, and the patient was discharged on postoperative day 3., Discussion: Surgery is the mainstream treatment for gallstone ileus. Multiple operations and surgical approaches have been described: enterolithotomy (EL), one-stage surgery (EL, cholecystectomy, and fistula closure), bowel resection, and two-stage surgery (EL and delayed cholecystectomy with fistula closure). The choice of the procedure depends on the patient's characteristics, comorbidities, and experience of the surgical team., Conclusion: In the emergency setting, a simple enterolithotomy with primary closure seems to be the optimal approach to solve the intestinal obstruction with low postoperative morbidity. The laparoscopic approach to gallstone ileus results in additional benefits for patients' recovery., (Copyright © 2021. Published by Elsevier Ltd.)

Colonic leiomyomas are rare. Their clinical presentation ranges from asymptomatic polyps detected on endoscopy to large symptomatic abdominopelvic masses. Imaging findings are usually non-specific, and percutaneous biopsy might help with differential diagnosis. However, radical surgery with negative margins is ultimately needed to rule out malignancy. We describe an uncommon presentation of a colonic leiomyoma mimicking a right hepatic lobe tumor on preoperative imaging. The robotic approach allowed a precise abdominal exploration with confirmation of colonic and hepatic infiltration and subsequent oncological en-block resection. Surgeons operating on hepatic tumors close to the right colic flexure should be aware of this diagnosis., (Published by Oxford University Press and JSCR Publishing Ltd. © The Author(s) 2021.)

Background: Trocar site hernia (TSH) is often underestimated after minimally invasive surgery. Scarce information is available about the incidence of TSH in patients undergoing laparoscopic hernioplasty. We aimed to evaluate the incidence and risk factors of umbilical TSH after laparoscopic TAPP hernioplasty in patients with and without an associated umbilical hernia., Methods: A retrospective analysis of a prospectively collected database of all patients who underwent laparoscopic inguinal TAPP repair during 2013-2018 was performed. After TAPP repair, the umbilical fascia was closed either by a figure-of-eight stitch with absorbable suture (G1) or by umbilical hernioplasty if it was present (G2). Multivariate logistic regression analysis was used to determine the TSH risk factors. Comparative evaluation regarding demographics, and operative and postoperative variables was performed., Results: A total of 535 laparoscopic TAPP repairs were included. There were 359 (67.1%) patients in G1 and 176 in G2 (32.9%). Surgical site infection was higher in G2 (G1: 0.6% vs G2: 5.7%, p = 0.001). Overall TSH rate was 3.9% after a mean follow-up of 20 (12-41) months. Performing a concomitant umbilical repair significantly increased the risk of umbilical TSH (G1: 2.2% vs G2: 7.4%, p = 0.004). TSH rates in G2 were similar in patients with simple suture or mesh repairs (p = 0.88). Rectus abdominis diastasis (OR 37.8, 95% CI:8.22-174.0, p < 0.001) and inguinal recurrence (OR 13.5, 95% CI:2.04-89.5, p = 0.007) were independent risk factors for TSH., Conclusion: Although trocar site hernia after laparoscopic TAPP repair has a low incidence, its risk is significantly increased in patients with a concomitant umbilical hernia repair, rectus abdominis diastasis, and/or inguinal recurrence., (© 2020.

Background: Intraoperative cholangiography (IOC) has been historically used to detect common bile duct (CBD) stones, delineate biliary anatomy, and avoid or promptly diagnose bile duct injuries (BDIs) during laparoscopic cholecystectomy (LC). We aimed to determine the usefulness of routine IOC during LC in an urban teaching hospital., Methods: A consecutive series of patients undergoing LC with routine IOC from 2016 to 2018 was prospectively analyzed. Primary outcomes of interest were: CBD stones, BDI, and anatomical variations of the biliary tract. Secondary outcomes of interest were: IOC success rate, IOC time, and readmission for residual lithiasis. A comparative analysis was performed between patients with and without preoperative suspicion of CBD stones., Results: A total of 1003 LC were analyzed; IOC was successful in 918 (91.5%) patients. Mean IOC time was 10 (4 to 30) minutes. Mean radiation received by the surgeon per procedure was 0.06 millisieverts (mSv). Normal IOC was found in 856 (93.2%) patients. CBD stones and aberrant biliary anatomy were present in 58 (6.3%) and 4 (0.4%) cases, respectively. Two patients (0.2%) underwent unnecessary CBD exploration because of false-positive IOC. Four patients (0.4%) with normal IOC were readmitted for residual CBD stones. Five (0.5%) minor BDI undetected by the IOC were diagnosed. Patients with preoperative suspicion of CBD stones had significantly higher rates of CBD stones detected on IOC as compared with those without suspicion (23.2% vs. 2.1%, P<0.0001)., Conclusion: Routine use of IOC resulted in low rates of BDI diagnosis, aberrant biliary anatomy identification and/or CBD stones detection. Selection of patients for IOC, rather than routine use of IOC appears a more reasonable approach., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Purpose: The number of bariatric revisional procedures is growing. Scarce evidence is available regarding the role and postoperative outcomes of robotic-assisted revisional bariatric surgery (RRBS). The aim of this study is to evaluate the safety and postoperative outcomes of RRBS., Materials and Methods: A retrospective analysis of a prospectively collected database of patients who underwent RRBS between 2012 and 2019 was performed. Primary outcomes of interest were 30-day major morbidity, mortality, length of hospital stay (LOS), urgent reoperation rates, and percentage of total weight loss (%TWL)., Results: RRBS was performed in 76 patients; among these 60 (78.9%) underwent conversion to Roux-en-Y gastric bypass (C-RYGB). Failed weight loss (76%) and gastroesophageal reflux (9.2%) were the main indications for revision. Primary bariatric procedures included gastric band (LAGB) (50%), sleeve gastrectomy (SG) (40.8%), and RYGB (6.6%). Major morbidity and mortality rates were 3.9% and 1.3%, respectively. Mean LOS was 2.1 days, and 3 patients (3.9%) required urgent reoperation. The %TWL at 3, 6, 12, and 24 months was 10.2%, 16.6%, 18.3%, and 22.4% respectively. Comparative analysis of C-RYGB after failed LAGB and SG showed similar morbidity. Higher readmission rates (SG: 22.2% vs. LAGB: 0%, p = 0.007) and lower %EWL at 3, 6, 12, and 24 months were found in C-RYGB after SG., Conclusion: This is one of the largest single-center series of RRBS published in the literature; the data indicate that robotic approach for revisional bariatric surgery is safe and helps achieving further weight loss. RRBS outcomes might be influenced by the primary procedure.

Background: Evidence is growing about the benefits of laparoscopic resection with primary anastomosis (RPA) in perforated diverticulitis. However, the role of a diverting ileostomy in this setting is unclear. The aim of this study was to analyze the outcomes of laparoscopic RPA with or without a proximal diversion in Hinchey III diverticulitis., Methods: This is a retrospective analysis of patients undergoing laparoscopic sigmoidectomy for perforated Hinchey III diverticulitis during the period 2000-2019. The sample was divided into two groups: RPA without diversion (G1) and RPA with protective ileostomy (G2). Primary outcomes of interest were 30-day overall morbidity, mortality, length of hospital stay (LOS), and urgent reoperation rates. Secondary outcomes of interest included operative time, readmission, and anastomotic leak rates., Results: Laparoscopic RPA was performed in 94 patients: 76 without diversion (G1) and 18 with proximal loop ileostomy (G2). Mortality (G1: 1.3% vs. G2: 0%, p = 0.6), urgent reoperation (G1: 7.9% vs. G2: 5.6%, p = 0.73), and anastomotic leak rates (G1: 5.3% vs. G2: 0%, p = 0.32) were comparable between groups. Higher overall morbidity (G1: 27.6% vs. G2: 55.6%, p = 0.02) and readmission rates (G1: 1.3% vs. G2: 11.1%, p = 0.03), and longer LOS (G1: 6.3 vs. G2: 9.2 days, p = 0.02) and operative time (G1: 182.4 vs. G2: 230.2 min, p = 0.003) were found in patients with proximal diversion., Conclusion: Laparoscopic RPA had favorable outcomes in selected patients with Hinchey III diverticulitis. The addition of a proximal ileostomy resulted in increased morbidity, readmissions, and length of stay. Further investigation is needed to establish which patients might benefit from proximal diversion.

Background: Surgical management of an asymptomatic inguinal hernia is controversial but given that most of the patients will develop symptoms, the hernioplasty seems to be a reasonable option. We aimed to compare postoperative outcomes after transabdominal preperitoneal (TAPP) repair between patients with symptomatic bilateral hernia (SBH) and patients with one symptomatic hernia and an asymptomatic contralateral hernia (ACH)., Methods: A consecutive series of patients undergoing bilateral laparoscopic TAPP from July 2014 to June 2018 were included. Symptomatic hernia was defined as a groin bulge associated to pain and altered patient's daily activities. Patients were divided into two groups, those with SBH and those with one symptomatic hernia in whom an ACH was diagnosed by physical examination or ultrasound when clinical assessment was inconclusive. Demographics, operative, and postoperative outcomes were compared. Quality of life (QoL) was assessed before and after surgery in both groups., Results: A total of 305 bilateral TAPP repairs were included; 102 (33, 4%) patients had SBH and 203 (66, 6%) had ACH. There were no significant differences between groups regarding age, gender, body mass index, active smoking, and comorbidities. Operative time (SBH: 125 vs. ACH: 132 min, p = 0.13) and overall 30-day morbidity were similar between groups (SBH: 14, 7% vs. ACH: 13, 8%, p = 0.82). After a mean follow-up of 30 (10-48) months, the recurrence rate was 1, 4% and 2, 2% in SBH and ACH, respectively (p = 0.53). QoL after surgery improved significantly and similarly in both groups., Conclusion: Bilateral laparoscopic TAPP in the setting of an asymptomatic hernia did not increase morbidity and had similar outcomes when compared to patients with bilateral symptoms. A comprehensive preoperative evaluation of the contralateral groin should be routinely performed, mainly by physical examination, and a bilateral repair may be proposed if an asymptomatic contralateral hernia is detected.

Background: Single-day discharge is a common practice among patients undergoing laparoscopic appendectomy (LA). We aimed to determine risk factors associated with readmission in patients with short hospital stay after LA., Methods: We performed a retrospective analysis of all patients who underwent LA during the period 2006-2019. Patients with length of hospital stay shorter than 24 h were included. Demographics, operative variables, and postoperative outcomes were analyzed. Multivariable logistic regression was performed to determine risk factors for readmission., Results: A total of 2009 LA were performed during the study period; 1506 (75%) patients had short hospital stay and were included in the analysis. Median age was 31 (14-85) years, and 720 (48%) were female. Mild peritonitis was diagnosed in 423 (28%) patients, and 121 (8%) had gangrenous/perforated appendicitis. Mean surgical time was 51(14-180) min. Conversion rate was 0.4%. There were 143 (9%) postoperative complications, including 29 (1.9%) patients with postoperative intra-abdominal abscess. Nine patients (0.6%) underwent reoperation, and only 26 (1.7%) patients were readmitted. The mean time to hospital readmission was 6 (1-14) days. Although age >50 years, obesity, mild peritonitis, and complicated appendicitis were more frequent among patients readmitted, only age >50 years (OR 3.54 95% CI 1.51-8.30) and mild peritonitis (OR 6.16 95% CI 1.80-34.93) were found as independent risk factors for readmission., Conclusion: Most patients undergoing LA can be safely discharged within 24 h of admission. Patients over 50 years old and/or with localized peritonitis have significantly higher risk of readmission and therefore may need a closer postoperative follow-up.

Background: Laparoscopic appendectomy (LA) is a common procedure among surgical trainees. However, first-year residents' involvement in this procedure is scarcely studied. We aimed to determine the safety and outcomes of LA performed by surgical interns early in their first year of surgical training., Materials and Methods: A retrospective review of all patients who underwent LA for acute appendicitis from 2006 to 2019 was performed. All patients operated by surgical interns were included. The sample was divided into 2 groups: LA performed during the first (G1) and last 3 months (G2) of their first year of residency. Demographics, operative variables, and postoperative outcomes were compared between groups., Results: A total of 2009 LA were performed during the study period; 1647 (82%) were done by surgical interns. A total of 934 LA were performed at both ends of the year; 505 belonged to G1 and 429 to G2. Each surgical intern performed a mean of 40 LA. Demographics, complicated appendicitis rates, and presence of peritonitis were comparable between groups. Operative time was longer in G1 (G1: 61 vs. G2: 52 min, P<0.0001). Major morbidity (G1: 2.1% vs. G2: 3.4%, P=0.2), postoperative intra-abdominal abscess rates (G1: 2.8% vs. G2: 2.8%, P=0.66), median length of hospital stay (G1: 1.9 vs. G2: 1.8 d, P=0.59), and readmission rates (G1: 1.6% vs. G2: 2%, P=0.73) were similar between groups. There was no mortality in the series., Conclusions: LA can be safely performed by supervised surgical interns early in their training. Despite a longer operative time, postoperative outcomes were favorable and similar as those achieved at the end of surgical internship., Competing Interests: The author declares no conflicts of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

Despite paraesophageal hernias (PEH) being a common disorder, several aspects of their management remain elusive. Elective surgery in asymptomatic patients, management of acute presentation, and other technical aspects such as utilization of mesh, fundoplication or gastropexy are some of the debated issues. The aim of this study was to review the available evidence in an attempt to clarify current controversial topics. PEH repair in an asymptomatic patient may be reasonable in selected patients to avoid potential morbidity of an emergent operation. In acute presentation, gastric decompression and resuscitation could allow to improve the patient's condition and refer the repair to a more experienced surgical team. When surgical repair is decided, laparoscopy is the optimal approach in most of the cases. Mesh should be used in selected patients such as those with large PEH or redo operations. While a fundoplication is recommended in the majority of patients to prevent postoperative reflux, a gastropexy can be used in selected cases to facilitate postoperative care., (© The Author(s) 2020.

Aim: Outcomes after resident involvement in emergent colectomies have rarely been studied. The aim of this study was to analyse the outcomes of laparoscopic sigmoidectomy for Hinchey III diverticulitis performed by residents., Method: This study was a retrospective analysis of patients undergoing laparoscopic sigmoidectomy for diverticulitis. The sample was divided into two groups: patients operated on by a supervised resident (SR) or a senior surgeon (SS). Supervising surgeons and SSs could be general surgeons (GSs) or colorectal surgeons (CSs). A SR was considered the first surgeon if he/she completed at least three of five defined steps of the procedure. The primary end-points included length of hospital stay (LOS), morbidity and 30-day mortality. A sub-analysis of patients operated on by a SR assisted by either a CS or GS was performed., Results: Supervised residents and SSs operated on 59 and 42 patients, respectively. The presence of a CS was more frequent in the SS group (SR 41% vs SS 81%, P < 0.001). LOS (SR 9.4 days vs SS 6.4 days, P = 0.04) was higher in the SR group. Overall morbidity (SR 39% vs SS 43%, P = 0.69) and 30-day mortality (SR 5% vs SS 5%, P = 0.94) were also comparable among the groups. Procedures performed by SRs and supervised by a CS were associated with lower morbidity (GS 48% vs CS 25%, P = 0.06) and mortality (GS 8% vs CS 0%, P = 0.26)., Conclusion: Laparoscopic sigmoidectomy for Hinchey III diverticulitis has comparable outcomes when performed by a supervised SR or a SS. Procedures performed by residents assisted by a CS seem to have better outcomes than those assisted by a GS., (Colorectal Disease © 2020 The Association of Coloproctology of Great Britain and Ireland.)

Anastomotic leak (AL) is the most feared complication after colorectal surgery and time to diagnosis is variable. The aim of this study was to analyze the outcomes of patient who had an AL during or after hospital discharge. A retrospective analysis of a prospectively collected database of all patients undergoing laparoscopic colorectal resections without proximal diversion during the period 2008-2018 was conducted. The sample was divided into two groups: patients who had AL during hospitalization (G1) and those who had AL after hospital discharge (G2). Demographics, operative variables and postoperative outcomes were compared between groups. A total of 853 patients were included; AL was diagnosed in 60 (7%) patients and was more frequent during initial hospitalization than after hospital discharge (G1: 49 (82%) vs. G2: 11 (18%), p < 0.001). Demographics were similar between groups. Most patients were treated with laparoscopic lavage and diverting ileostomy in both groups (G1: 92% vs. G2: 82%, p = 0.30). Severity of peritonitis at reoperation and length of hospital stay after AL were similar between groups (G1: 11 vs. G2: 9 days, p = 0.54). Overall postoperative morbidity (G1: 57% vs. G2: 36%, p = 0.31), mortality (G1: 10% vs. G2: 27%, p = 0.15) and intestinal reconstruction rate (G1: 92% vs. G2: 100%, p = 1) were similar between groups. Outpatient onset of anastomotic leak did not increase the severity of peritonitis, had no impact on the type of treatment performed, and showed similar postoperative morbidity and mortality as compared to those having AL during hospitalization.

Introduction: Increases in the rates of esophageal adenocarcinoma (EAC) have paralleled rises in the prevalence of overweight and obesity. Despite not being fully understood, obesity-related EAC seems to have different carcinogenic pathways., Areas Covered: This comprehensive review will thoroughly evaluate the current literature, describing the underlying mechanisms that help understanding the strong association between obesity and esophageal cancer., Expert Commentary: The risk of esophageal cancer among obese individuals could be partially explained by several factors: high prevalence of GERD; linear association between central adiposity and Barrett´s esophagus development; low levels of adiponectin and high levels of leptin that alter cell proliferation processes; insulin-resistant state that creates a tumorigenesis environment; and changes in the esophageal microbiota due to unhealthy dietary habits that promote carcinogenesis. In addition, a large proportion of obese patients are undergoing sleeve gastrectomy which can worsen GERD or cause de novo reflux, esophagitis, and Barrett´s metaplasia.

AI (Artificial intelligence) is an interdisciplinary field aimed at the development of algorithms to endow machines with the capability of executing cognitive tasks. The number of publications regarding AI and surgery has increased dramatically over the last two decades. This phenomenon can partly be explained by the exponential growth in computing power available to the largest AI training runs. AI can be classified into different sub-domains with extensive potential clinical applications in the surgical setting. AI will increasingly become a major component of clinical practice in surgery. The aim of the present Narrative Review is to give a general introduction and summarized overview of AI, as well as to present additional remarks on potential surgical applications and future perspectives in surgery.

Background: Laparoscopic primary anastomosis (PA) without diversion for diverticulitis has historically been confined to the elective setting. Hartmann's procedure is associated with high morbidity rates that might be reduced with less invasive and one-step approaches. The aim of this study was to analyze the results of laparoscopic PA without diversion in Hinchey III perforated diverticulitis., Methods: We performed a retrospective analysis of a prospectively collected database of all patients who underwent laparoscopic sigmoidectomy for diverticular disease during the period 2000-2018. The sample was divided in two groups: elective laparoscopic sigmoid resection for recurrent diverticulitis (G1) and emergent laparoscopic sigmoidectomy for Hinchey III diverticulitis (G2). Demographics, operative variables, and postoperative outcomes were compared between groups., Results: A total of 415 patients underwent laparoscopic sigmoid resection for diverticular disease. PA without diversion was performed in 351 patients; 278 (79.2%) belonged to G1 (recurrent diverticulitis) and 73 (20.8%) to G2 (perforated diverticulitis). Median age, gender, and BMI score were similar in both groups. Patients with ASA III score were more frequent in G2 (p: 0.02). Conversion rate (G1: 4% vs. G2: 18%, p < 0.001), operative time (G1: 157 min vs. G2: 183 min, p < 0.001), and median length of hospital stay (G1: 3 days vs. G2: 5 days, p < 0.001) were significantly higher in G2. Overall postoperative morbidity (G1: 22.3% vs. G2: 28.7%, p = 0.27) and anastomotic leak rate (G1: 5.7% vs. G2: 5.4%, p = 0.92) were similar between groups. There was no mortality in G1 and one patient (1.3%) died in G2 (p = 0.21)., Conclusion: Laparoscopic sigmoid resection without diversion is feasible and safe in patients with perforated diverticulitis. In centers with vast experience in laparoscopic colorectal surgery, patients undergoing this procedure have similar morbidity and mortality to those undergoing elective sigmoidectomy.

Purpose: Laparoscopic inguinal hernia repair (LIHR) has demonstrated multiple benefits. However, long-term results regarding recurrence and quality of life (QoL) are still on debate. We aimed to analyze postoperative outcomes with long-term follow-up after LIHR., Methods: A consecutive series from December 2012 to May 2017 of laparoscopic TAPP was included. A minimum of 6 months of follow-up was required for inclusion. The sample was divided into two groups, G1: patients with recurrence and G2: patients without recurrence. Patient's characteristics, operative variables and postoperative outcomes were analyzed. A QoL survey (Eura-HS QoL) was performed in the pre- and postoperative period., Results: A total of 717 laparoscopic TAPP were performed in 443 patients. On univariate analysis, smoking, previous recurrence, mesh size smaller than 12 × 15 cm and surgical teams with less than 30 cases/year showed an increased recurrence rate (p < 0.05). But only smoking and less experienced teams were statistically significant on multivariate analysis (p < 0.01). After a 2-year follow-up, recurrence rate was 1.5%, while it increased to 2.6% (n = 19) at 5-year follow-up. Sixty percent of patients answered QoL survey. Average preoperative scores of pain, activities restriction and aesthetic dissatisfaction improved significantly after 6 months of follow-up in patients without recurrence., Conclusions: After LIHR, quality of life shows a significant improvement in all parameters. Extending follow-up beyond 2 years after laparoscopic TAPP allows a more accurate assessment of recurrence rate. Smoking and inexperienced teams were significant risk factors for its development.
