Two-Year Results of Sleeve Gastrectomy Combined with Posterior Fundoplication for Obesity Patients with Gastroesophageal Reflux Disease.

INTRODUCTION: Currently, gastroesophageal reflux disease (GERD) is the main side effect after sleeve gastrectomy (SG), causing discomfort and potential long-term risks. Surgical techniques combining fundoplication with SG are being evaluated to limit postoperative GERD. METHODS: This single-center retrospective study evaluated patients who underwent SG with posterior fundoplication in the context of GERD between 2018 and 2021, with postoperative follow-up up to 24 months. The results were compared to a control group (ratio 1 to 4) who had SG without fundoplication. Observed total weight loss (TWL) was compared to predicted TWL using the Sophia multinational study's machine learning-based calculator. RESULTS: The series included 22 patients (mean body mass index 44.4 kg/m2) with GERD conditions: GERD symptoms (n = 15), hiatal hernia (n = 6), esophagitis (n = 7), and Barrett's esophagus (n = 5). Two patients required reoperation, including one for valve perforation. At 2 years, GERD was present in three patients (13.6%), including two who regularly took proton pump inhibitors. Compared to the control group (n=88), the frequency of GERD persisting at 2 years was significantly reduced in the SG with fundoplication group (p=0.05). The TWL at 12 and 24 months was 27.7% and 26.1%, respectively, with no significant difference compared to the weight predicted by the model, nor compared to the control group. CONCLUSION: The combination of posterior fundoplication with SG can be proposed in patients with GERD who have a contraindication to Roux-en-Y gastric bypass. Specific morbidity may exist at the beginning of the experience.

Quality of life after sigmoid diverticulitis: A review.

INTRODUCTION: Diverticular disease, including diverticulitis, begins when the patient becomes symptomatic. Sigmoid diverticulitis corresponds to inflammation/infection of a diverticulum of the sigmoid colon. Among diverticulosis patients, 4.3% develop diverticulitis, a frequent pathology that can entail major functional disorders. Following sigmoid diverticulitis, few studies have assessed functional disorders and quality of life, a multidimensional concept comprising physical, psychological and mental dimensions, as well as social relations. OBJECTIVE: The purpose of this work is to report current published data on the quality of life of patients having had sigmoid diverticulitis. RESULTS: Following uncomplicated sigmoid diverticulitis, long-term quality of life does not substantially differ between patients having undergone antibiotic therapy and those having only received symptomatic treatment. As for patients having experienced recurrent events, their quality of life seems improved by elective surgery. Following Hinchey I/II sigmoid diverticulitis, elective surgery seems to improve quality of life, notwithstanding a 10% risk of postoperative complications. Following sigmoid diverticulitis, while emergency surgery seems not to have greater impact on quality of life than elective surgery, the surgical technique employed in an emergency setting seems to have an impact, particularly with regard to the physical and mental components of quality of life. CONCLUSION: Assessment of quality of life is of fundamental importance in diverticular disease and should orient operative indications, particularly in an elective context.

The falciform/round ligament "flooring," an effective method to reduce life-threatening post-pancreatectomy hemorrhage occurrence.

PURPOSE: Late post-pancreatectomy hemorrhage (PPH) represents the most severe complication after pancreatic surgery. We have measured the efficacy of major vessels "flooring" with falciform/round ligament to prevent life-threatening grade C late PPH after pancreaticoduodenectomy (PD) and distal pancreatectomy (DP). METHODS: All consecutive patients who underwent PD and DP between 2013 and 2021 were retrospectively reviewed on a prospectively maintained database. The cohort was divided in two groups: "flooring" vs. "no flooring" method group. The "no flooring" group had omental flap interposition. Patient characteristics and operative and postoperative data including clinically relevant postoperative pancreatic fistula (CR-POPF), late PPH (grade B and C), and 90-day mortality were compared between the two groups. RESULTS: Two hundred and forty patients underwent pancreatic resections, including 143 PD and 97 DP. The "flooring" method was performed in 61 patients (39 PD and 22 DP). No difference was found between the two groups concerning severe morbidity, CR-POPF, delayed PPH, and mortality rate. The rate of patients requiring postoperative intensive care unit was lower in the "flooring" than in the "no flooring" method group (11.5% vs. 25.1%, p = 0.030). Among patients with grade B/C late PPH (n = 30), the rate of life-threatening grade C late PPH was lower in the "flooring" than in the "no flooring" method group (28.6% (n = 2/7) vs. 82.6% (n = 19/24), p = 0.014). Risk factor analysis showed that the "flooring" method was the only protective factor against grade C late PPH occurrence (p = 0.013). CONCLUSION: The "flooring" method using the falciform/round ligament should be considered during pancreatectomies to reduce the occurrence of life-threatening grade C late PPH.

An Ex Situ Cadaver Liver Training Model Continuously Pressurized to Simulate Specific Skills Involved in Laparoscopic Liver Resection: the Lap-Liver Trainer.

BACKGROUND: Laparoscopic liver resection (LLR) requires delicate skills. The aim of the study was to develop a training model mimicking as much as possible intraoperative bleeding and bile leakage during LLR. We also assessed the educational value of the training model. METHODS: The Lap-liver trainer (LLT) combined a continuously pressurized ex situ cadaver liver and a customized mannequin. The customized mannequin was designed by computer-aided design and manufactured by 3D printing. The left lateral sectionectomy (LLS) was chosen to assess the feasibility of a LLR with the LLT. Eighteen volunteers were recruited to perform LLS and to assess the educational value of the LLT using a Likert scale. RESULTS: The customized mannequin consisted of a close laparoscopic training device based on a simplified reconstruction of the abdominal cavity in laparoscopic conditions. Ex situ cadaver livers were pressurized to simulate blood and bile supplies. Each expert surgeon (n = 3) performed two LLS. They were highly satisfied of simulation conditions (4.80 ± 0.45) and strongly recommended that the LLT should be incorporated into a teaching program (5.00 ± 0.0). Eight novice and 4 intermediate surgeons completed a teaching program and performed a LLS. Overall, the level of satisfaction was high (4.92 ± 0.29), and performing such a procedure under simulation conditions benefited their learning and clinical practice (4.92 ± 0.29). CONCLUSIONS: The LLT could provide better opportunities for trainees to acquire and practice LLR skills in a more realistic environment and to improve their ability to deal with specific events related to LLR.

Feasibility of a new bariatric fully endoscopic duodenal-jejunal bypass: a pilot study in adult obese pigs.

This study assessed a new natural orifice transluminal endoscopic surgery (NOTES) bariatric endoscopic procedure in obese adult pigs. This 14-week prospective study compared 6 adult male Yucatan test pigs with baseline mean age 1.5 years to 2 control pigs. The test pigs received a fully endoscopic NOTES-based duodenal-jejunal bypass including measurement of the bypassed limb and creation of a gastrojejunal anastomosis (GJA) using a gastrojejunal lumen-apposing metal stent (GJ-LAMS) at Week 0, placement of a duodenal exclusion device (DED) at Week 2, and endoscopic examinations at Weeks 6 and 10. At Week 14, the pigs were sacrificed for necropsy. All endoscopic procedures were technically successful. By Week 14, the controls had gained a mean 1.1 ± 2.1 kg (+ 1.6%) while the intervention animals lost a mean 6.8 ± 3.9 kg (- 10.5%) since baseline. GJ-LAMS migrations occurred in 3 pigs, two of which also had DED migration and/or partial dislocation. Two other pigs died, one with aberrant splenic vein positioning near the GJA and the other from an unknown cause. An endoscopic bariatric bypass procedure with controlled bypass length was technically successful in all the cases and led to weight loss in test animals. Safety concerns must be further addressed.

Predictive factors of non-operative management failure in 494 blunt liver injuries: a multicenter retrospective study.

Non-operative management (NOM) has become the major treatment of blunt liver trauma (BLT) with a NOM failure rate of 3-15% due to liver-related complications. The aim of the study was to determine the predictive factors and a risk-stratified score of NOM failure. From 2013 to 2021, all patients with BLT in three trauma centers were included; clinical, biological, radiological and outcome data were retrospectively analyzed. Predictive factors and a risk-stratified score associated with NOM failure were identified. Four hundred and ninety-four patients with BLT were included. Among them, 80 (16.2%) had isolated BLT. Fifty-nine patients (11.9%) underwent emergent operative management (OM) on the day of admission and 435 (88.1%) had a NOM. NOM failure rate was 11.5%. Patients with a NOM failure more frequently had a hemoperitoneum (p < 0.001), liver bleeding (p < 0.001), blood transfusion (p < 0.001) and angioembolization (p < 0.001) compared to patient with a successful NOM. In multivariate analysis, the presence of hemoperitoneum (OR = 5.71; 95 CI [1.29-25.45]), angioembolization (OR = 8.73; 95 CI [2.04-38.44] and severe liver injury (AAST IV or V) (OR = 8.97; 95 CI [3.36-23.99]) were independent predictive factors of NOM failure. When these three factors were associated, NOM failure rate was 83.3%. The AAST grade, the presence of hemoperitoneum and the realization of liver angioembolization on the day of admission are three independent predictive factors of NOM failure. Our risk-score based on these three factors stratify the risk of NOM failure in BLT and could be used for a more appropriate level of medical survey adapted to each patient. Level of evidence: prospective observational cohort study, Level III.

Feasibility of Conversion of a New Bariatric Fully Endoscopic Bypass Procedure to Bariatric Surgery: a Porcine Pilot Study.

PURPOSE: Bariatric endoscopic procedures are emerging as alternatives to bariatric surgical procedures. This study aimed to assess if a natural orifice transluminal endoscopic surgery (NOTES) bariatric procedure could be converted to a surgical duodenal-jejunal bypass (DJB) or sleeve gastrectomy (SG). MATERIALS AND METHODS: This 12-week prospective study compared 4 test pigs to 3 control (no procedures) pigs aged 3 months at baseline. The test pigs received a fully endoscopic NOTES-based bypass including measurement of the bypassed limb and creation of a gastrojejunal anastomosis (GJA) using gastrojejunal lumen-apposing metal stents (GJ-LAMS) at Week 0, placement of a duodenal exclusion device (DED) at Week 2, and randomization to DJB or SG surgery at Week 8 with subsequent 4-week follow-up. At Week 12, the pigs were sacrificed and necropsy was performed. RESULTS: Endoscopic procedures were technically successful. One pig did not receive a DED due to early GJ-LAMS migration leading to premature closure of the GJA. At Week 8, all 4 pigs were doing well, and the remaining 3 GJ-LAMS and 3 DEDs were uneventfully endoscopically removed. Two one-anastomosis DJB were performed, and 2 SG were performed, closing in one case the site of the previous GJA. The surgical procedures were technically feasible and uneventful during follow-up. Necropsy assessments showed no local or peritoneal inflammation or abscess and no leakage or fistula. CONCLUSION: An endoscopic bariatric bypass can be transitioned to a one-anastomosis duodenal-jejunal bypass or sleeve gastrectomy, without complications.

First fully endoscopic metabolic procedure with NOTES gastrojejunostomy, controlled bypass length and duodenal exclusion: a 9-month porcine study.

We conducted a pilot study of a potential endoscopic alternative to bariatric surgery. We developed a Natural Orifice Transluminal Endoscopic Surgery (NOTES) gastric bypass with controlled bypass limb length using four new devices including a dedicated lumen-apposing metal stent (GJ-LAMS) and pyloric duodenal exclusion device (DED). We evaluated procedural technical success, weight change from baseline, and adverse events in growing Landrace/Large-White pigs through 38 weeks after GJ-LAMS placement. Six pigs (age 2.5 months, mean baseline weight 26.1 ± 2.7 kg) had initial GJ-LAMS placement with controlled bypass limb length, followed by DED placement at 2 weeks. Technical success was 100%. GJ-LAMS migrated in 3 of 6, and DED migrated in 3 of 5 surviving pigs after mucosal abrasion. One pig died by Day 94. At 38 weeks, necropsy showed 100-240 cm limb length except for one at 760 cm. Weight gain was significantly lower in the pigs that underwent endoscopic bypass procedures compared to expected weight for age. This first survival study of a fully endoscopic controlled bypass length gastrojejunostomy with duodenal exclusion in a growing porcine model showed high technical success but significant adverse events. Future studies will include procedural and device optimizations and comparison to a control group.

New 5-mm laparoscopic pneumodissector device to improve laparoscopic dissection: an experimental study of its safety in a swine model.

BACKGROUND: To improve the laparoscopic surgical dissection, the aim of the study was to assess the safety of burst of high-pressure CO2 using a 5-mm laparoscopic pneumodissector (PD) operating at different flow rates and for different operating times regarding the risk of gas embolism (GE) in a swine model. METHODS: The first step was to define the settings use of the PD device ensuring no GE. Successive procedures were conducted by laparotomy: cholecystectomy, the PD was placed 10 mm deep in the liver and the PD was directly introduced into the lumen of the inferior vena cava. Different PD flow rates of 5, 10, and 15 mL/s were used. The second step was to assess the safety of the device (PD group) during a laparoscopic dissection task (cystic and hepatic pedicles dissection, cholecystectomy and right nephrectomy) in comparison with the use of a standard laparoscopic hook device (control group). PD flow rate was 10 mL/s and consecutive burst of high-pressure CO2 was delivered for 3-5 s. RESULTS: In the first step (n = 17 swine), no GE occurred during cholecystectomy regardless of the PD flow rate used. When the PD was placed in the liver or into the inferior vena cava, no severe or fatal GE occurred when a burst of high-pressure CO2 was applied for 3 or 5 s with PD flow rates of 5 and 10 mL/s. In the second step (PD group, n = 10; control group, n = 10), no GE occurred in the PD group. The use of the PD did not increase operative time or blood loss. The quality of the dissection was significantly improved compared to the control group. CONCLUSIONS: The 5-mm laparoscopic PD appears to be free from CO2 GE risk when consecutive bursts of high-pressure CO2 are delivered for 3-5 s with a flow rate of 10 mL/s.

Development of a novel educational tool to assess skills in laparoscopic liver surgery using the Delphi methodology: the laparoscopic liver skills scale (LLSS).

BACKGROUND: No specific performance assessment scales have been reported in laparoscopic liver resection. This study aimed at developing an objective scale specific for the assessment of technical skills for wedge resection in anterior segments (WRAS) and left lateral sectionectomy (LLS). METHODS: A laparoscopic liver skills scale (LLSS) was developed using a hierarchical task analysis. A Delphi method obtained consensus among five international experts on relevant steps that should be included into the LLSS for assessment of operative performances. The consensus was predefined using Cronbach's alpha > 0.80. RESULTS: A semi-structured review extracted 15 essential subtasks for full laparoscopic WRAS and LLS for evaluation in the Delphi survey. Two rounds of the survey were conducted. Three over 15 subtasks did not reach the predefined level of consensus. Based on the expert's comments, 13 subtasks were reformulated, 4 subtasks were added, and a revised skills scale was developed. After the 2nd round survey (Cronbach's alpha 0.84), 19 subtasks were adopted. The LLSS was composed of three main parts: patient positioning and intraoperative preparation (task 1 to 8), the core part of the WRAS and LLS procedure (tasks 9 to 14), and completion of procedure (task 15 to 19). CONCLUSIONS: The LLSS was developed for measuring the skill set for the education of safe and secure laparoscopic WRAS and LLS procedures in a dedicated training program. After validation, this scale could be also used as an assessment tool in the operating room and extrapolated as an operative roadmap to other complex procedures.

Severe acute ischemic colitis: What is the place of endoscopy in the management strategy?

Background and study aims Ischemic colitis (IC) is potentially lethal. Clinical and biology information and results of computed tomography (CT) scan and/or colonoscopy are used to assess its severity. However, decision-making about therapy remains a challenge. Patients and methods This was a retrospective, single-center study between 2006 and 2015. Patients with severe IC who underwent endoscopic evaluation were included. The aims were to determine outcomes depending on endoscopic findings and assess the role of endoscopy in the management. Results A total of 71 patients were included (men = 48 (68%), mean age = 71 ±â€Š13 years). There was hemodynamic instability in 29 patients (41 %) and severity signs on CT scan in 18 (38 %). Twenty-nine patients (41 %) underwent surgery and 24 (34 %) died. The endoscopic grades were: 15 grade 1 (21 %), 32 grade 2 (45 %), and 24 grade 3 (34%). Regarding patients with grade 3 IC, 55 % had hemodynamic instability, 58 % had severity signs on CT scan, 68 % underwent surgery, and 55 % died. The decision to perform surgery was based on hemodynamic status in 62 % of cases, CT scan data in 14 %, endoscopic findings in 10 %, and other in 14 %. Colectomy was more frequent in patients with grade 3 IC ( P  < 0.05). A mismatch between mucosal aspect (necrosis) and serous (normal) was observed in 13 patients (46 %). Risk factors for colectomy in univariate analysis were aortic aneurysm surgery, hemodynamic instability, no colic enhancement on CT scan, and endoscopic grade 3. Risk factors for mortality in multivariate analysis were hemodynamic instability, colectomy, and Charlson score > 5 ( P  < 0.05). Conclusions This study suggests a low impact of endoscopy on surgical decision making. Hemodynamic instability was the first indication for colectomy. A discrepancy between endoscopic mucosal (necrosis) and surgical serous (normal) aspects was frequently noted.

Delayed post-pancreatectomy hemorrhage and bleeding recurrence after percutaneous endovascular treatment: risk factors from a bi-centric study of 307 consecutive patients.

PURPOSE: Delayed post-pancreatectomy hemorrhage (PPH) is still one of the most dreaded complications after pancreatic surgery. Its management is now focused on percutaneous endovascular treatments (PETs). METHODS: Between 2013 and 2019, 307 patients underwent pancreatic resection. The first endpoint of this study was to determine predictive factors of delayed PPH. The second endpoint was to describe the management of intra-abdominal abscesses (IAA). The third endpoint was to identify risk factors of bleeding recurrence after PET. Patients were divided into two cohorts: A retrospective analysis was performed ("cohort 1," "learning set") to highlight predictive factors of delayed PPH. Then, we validated it on a prospective maintained cohort, analyzed retrospectively ("cohort 2," "validation set"). Second and third endpoints studies were made on the entire cohort. RESULTS: In cohort 1, including 180 patients, 24 experienced delayed PPH. Multivariate analysis revealed that POPF diagnosis on postoperative day (POD) 3 (p=0.004) and IAA (p=0.001) were independent predictive factors of delayed PPH. In cohort 2, association of POPF diagnosis on POD 3 and IAA was strongly associated with delayed PPH (area under the curve [AUC] 0.80; 95% confidence interval [CI] [0.59-0.94]; p=0.003). Concerning our second endpoint, delayed PPH occurred less frequently in patients who underwent postoperative drainage procedure than in patients without IAA drainage (p=0.002). Concerning our third endpoint, a higher body mass index (BMI) (p=0.027), occurrence of postoperative IAA (p=0.030), and undrained IAA (p=0.011) were associated with bleeding recurrence after the first PET procedure. CONCLUSION: POPF diagnosis on POD 3 and intra-abdominal abscesses are independent predictive factors of delayed PPH. Therefore, patients presenting an insufficiently drained POPF leading to intra-abdominal abscess after pancreatic surgery should be considered as a high-risk situation of delayed PPH. High BMI, occurrence of postoperative IAA, and undrained IAA were associated with recurrence of bleeding after PET.

Intra-pancreatic distal cholangiocarcinoma and pancreatic ductal adenocarcinoma: a common short and long-term prognosis?

The aim of the study was to compare histological features, postoperative outcomes, and long-term prognostic factors after pancreaticoduodenectomy for distal cholangiocarcinoma and pancreatic ductal adenocarcinoma. From 2005 to 2017, 188 pancreaticoduodenectomies (pancreatic ductal adenocarcinoma n = 151, distal cholangiocarcinoma n = 37) were included. Postoperative outcomes were compared after matching on pancreatic gland texture and main pancreatic duct size. Matching according to tumor size, lymph node invasion and resection margin was used to compare overall and disease-free survival. Distal cholangiocarcinoma patients had more often "soft" pancreatic gland (P = 0.002) and small size main pancreatic duct (P = 0.001). Pancreatic ductal adenocarcinoma patients had larger tumors (P = 0.009), and higher lymph node ratio (P = 0.017). Severe morbidity (P = 0.023) and clinically relevant pancreatic fistula (P = 0.018) were higher in distal cholangiocarcinoma patients. After matching on gland texture and main pancreatic duct diameter, clinically relevant postoperative pancreatic fistula was still more frequent in distal cholangiocarcinoma patients (P = 0.007). Tumor size > 20 mm was predictive of impaired overall survival (P = 0.024) and disease-free survival (P = 0.003), tumor differentiation (P = 0.027) was predictive of impaired overall survival. Survival outcomes for distal cholangiocarcinoma and pancreatic ductal cholangiocarcinoma were similar after matching patients according to tumor size, lymph node invasion and resection margin. Long-term outcomes after pancreaticoduodenectomy for distal cholangiocarcinoma and pancreatic ductal adenocarcinoma patients are similar. Postoperative course is more complicated after pancreaticoduodenectomy for distal cholangiocarcinoma than pancreatic ductal adenocarcinoma. After pancreaticoduodenectomy, patients with distal cholangiocarcinoma and pancreatic ductal adenocarcinoma have similar long-term oncological outcomes.

French survey on a cohort of emergency general surgery modifications induced by lockdown of the SARS-CoV-2 pandemic.

PURPOSE: The brutal COVID-19 pandemic has majorly impacted populations and health systems, and surgeons have observed dramatic changes in their daily clinical activities. A survey of French digestive surgeons was conducted to assess these changes. METHODS: An electronic survey was sent to French digestive and general surgeons in the Societe Francaise de Chirurgie Digestive (SFCD) to assess the surgeons' daily activity during the pandemic and investigate changes in patients' management. The care deviations were classified as delay of management, modification of strategy, or modification of organization, and the impact of these changes on patients was evaluated by the surgeon's estimation of loss of chance. RESULTS: A major reduction in surgical elective activity was observed in 50 (75%) of the 67 hospitals that responded. Of these, 48 hospitals (71.6%) reported receiving SARS-CoV-2 patients. A deviation from usual care was observed in 10% of patients admitted for emergency general surgery. Among 140 patients presenting a deviation from usual care, 74 (52.9%) had delayed management, 53 (37.9%) had a modification of strategy, and 64 (45.7%) had a modification of organization. Medical treatment instead of surgical treatment was decided for 37 (26.4%) patients, resulting in a high loss of chance for 6 patients. Delays (p < 0.001) and a switch from surgical to medical treatment (p = 0.002) were independently correlated with overall loss of chance based on multivariate analysis. CONCLUSION: This study highlighted the deviations in general emergency surgery patients and provided implications for the solutions that should be implemented during a new health crisis.

Lung Ultrasound Findings in the Postanesthesia Care Unit Are Associated With Outcome After Major Surgery: A Prospective Observational Study in a High-Risk Cohort.

BACKGROUND: Postoperative pulmonary complications are associated with increased morbidity. Identifying patients at higher risk for such complications may allow preemptive treatment. METHODS: Patients with an American Society of Anesthesiologists (ASA) score >1 and who were scheduled for major surgery of >2 hours were enrolled in a single-center prospective study. After extubation, lung ultrasound was performed after a median time of 60 minutes by 2 certified anesthesiologists in the postanesthesia care unit after a standardized tracheal extubation. Postoperative pulmonary complications occurring within 8 postoperative days were recorded. The association between lung ultrasound findings and postoperative pulmonary complications was analyzed using logistic regression models. RESULTS: Among the 327 patients included, 69 (19%) developed postoperative pulmonary complications. The lung ultrasound score was higher in the patients who developed postoperative pulmonary complications (12 [7-18] vs 8 [4-12]; P < .001). The odds ratio for pulmonary complications in patients who had a pleural effusion detected by lung ultrasound was 3.7 (95% confidence interval, 1.2-11.7). The hospital death rate was also higher in patients with pleural effusions (22% vs 1.3%; P < .001). Patients with pulmonary consolidations on lung ultrasound had a higher risk of postoperative mechanical ventilation (17% vs 5.1%; P = .001). In all patients, the area under the curve for predicting postoperative pulmonary complications was 0.64 (95% confidence interval, 0.57-0.71). CONCLUSIONS: When lung ultrasound is performed precociously <2 hours after extubation, detection of immediate postoperative alveolar consolidation and pleural effusion by lung ultrasound is associated with postoperative pulmonary complications and morbi-mortality. Further study is needed to determine the effect of ultrasound-guided intervention for patients at high risk of postoperative pulmonary complications.

Laparoscopic rectal dissection preserves erectile function after ileal pouch-anal anastomosis: a two-centre study.

AIM: Few studies have been published on erectile function after ileal pouch-anal anastomosis (IPAA) and, unlike in women, male fertility after IPAA has never been assessed. The primary objective was to assess the impact of IPAA on erectile function. The secondary objective was to assess the impact of IPAA on male fertility. METHODS: All of the male patients who underwent IPAA in two university care centres between 2003 and 2017, aged 70 years or less at the time of operation, were included. Forty-eight per cent of the patients responded to the international index of erectile function, the Jorge-Wexner score and a fertility questionnaire. All demographic and perioperative data were prospectively collected. Fertility results were compared with those of a control group undergoing appendectomy, matched for age at the time of operation, desire for paternity and length of follow-up. RESULTS: One hundred and thirty-nine patients were included, among which 46 (33%) presented with erectile dysfunction and 14 (10%) with severe erectile dysfunction. Age older than 50 years (OR 0.27, 95% CI 0.12-0.62, P = 0.002) and rectal dissection performed by open surgery (OR 4.16, 95% CI 1.62-10.65, P = 0.003) were independent risk factors for erectile dysfunction. There was no infertility after IPAA compared with controls: indeed, 23 (16%) IPAA patients presented with pregnancy in their couple versus 27 (22%) controls (P = 0.29), whereas 36 (26%) IPAA patients and 34 (28%) controls (P = 0.80) expressed paternity desire. CONCLUSION: A total laparoscopic approach, including rectal dissection, should be preferred to preserve erectile function. Male fertility is not impaired after IPAA.

Prospective study on predictability of complications by pancreatic surgeons.

PURPOSE: We evaluated the intuition of expert pancreatic surgeons, in predicting the associated risk of pancreatic resection and compared this "intuition" to actual operative follow-up. The objective was to avoid major complications following pancreatic resection, which remains a challenge. METHODS: From January 2015 to February 2018, all patients who were 18 years old or more undergoing a pancreatic resection (pancreaticoduodenectomy [PD], distal pancreatectomy [DP], or central pancreatectomy [CP]) for pancreatic lesions were included. Preoperatively and postoperatively, all surgeons completed a form assessing the expected potential occurrence of clinically relevant postoperative pancreatic fistula (CR-POPF: grade B or C), postoperative hemorrhage, and length of stay. RESULTS: Preoperative intuition was assessed for 101 patients for 52 PD, 44 DP, and 5 CP cases. Overall mortality and morbidity rates were 6.9% (n = 7) and 67.3% (n = 68), respectively, and 38 patients (37.6%) developed a POPF, including 27 (26.7%) CR-POPF. Concordance between preoperative intuition of CR-POPF occurrence and reality was minimal, with a Cohen's kappa coefficient (κ) of 0.175 (P value = 0.009), and the same result was obtained between postoperative intuition and reality (κ = 0.351; P < 0.001). When the pancreatic parenchyma was hard, surgeons predicted the absence of CR-POPF with a negative predictive value of 91.3%. However, they were not able to predict the occurrence of CR-POPF when the pancreas was soft (positive predictive value 48%). CONCLUSIONS: This study assessed for the first time the surgeon's intuition in pancreatic surgery, and demonstrated that pancreatic surgeons cannot accurately assess outcomes except when the pancreatic parenchyma is hard.

Mesh Repair in Crohn's Disease: A Case-Matched Multicenter Study in 234 Patients.

BACKGROUND: There are no specific guidelines for ventral hernia management in Crohn's disease (CD) patients. We aimed to assess the risk of septic morbidity after mesh repair in CD. METHODS: This was a retrospective multicentre study comparing CD and non-CD patients undergoing mesh repair for ventral hernia (primary or incisional hernia). Controls were matched 1:1 for the presence of a stoma, history of surgical sepsis, hernia size and Ventral Hernia Working Group (VHWG) score. All demographic, pre-, intra- and postoperative data were retrieved, including long-term data. RESULTS: We included 234 patients, with 114 CD patients. Both groups had comparable VHWG scores (p = 0.12), hernia sizes (p = 0.11), ASA scores ≥ 3 (p = 0.70), body mass index values (p = 0.14), presence of stoma (CD 21.9% vs. controls 15%, p = 0.16), history of sepsis (14% vs. 6.7%, p = 0.23), rates of malnutrition (4.4% vs. 1.7%, p = 0.46), rates of incisional hernia (93% vs. 95%, p = 0.68) and concomitant procedures (18.4% vs. 11.7%, p = 0.12). CD patients carried a higher risk of postoperative septic morbidity (18.4% vs. 5%, p = 0.001), entero-prosthetic fistula (7% vs. 0, p < 0.01) and mesh withdrawals (5.3% vs. 0, p = 0.011). Ventral hernia recurrence rates were similar (14% vs. 8.3%, p = 0.15). In the univariate analysis, the risk factors for septic morbidity were CD (p = 0.001), malnutrition (p = 0.004), use of biological mesh (p < 0.0001) and concomitant procedure (p = 0.004). The mesh position, the means used for mesh fixation as well as the presence of a stoma were not identified as risk factors. CONCLUSIONS: CD seems to be a risk factor for septic morbidity after mesh repair.

Implementation of a Surgical Simulation Care Pathway Approach to Training in Emergency Abdominal Surgery.

BACKGROUND: Simulation-based care pathway approach (CPA) training is a novel approach in surgical education. The objective of the present study was to determine whether CPA was feasible for training surgical residents and could improve efficiency in patients' management. A common disease was chosen: acute appendicitis. METHODS: All five junior residents of our department were trained in CPA: preoperative CPA consisted in virtual patients (VPs) presenting with acute right iliac fossa pain; intraoperative CPA involved a virtual competency-based curriculum for laparoscopic appendectomy (LAPP); finally, post-operative VP were reviewed after LAPP. Thirty-eight patients undergoing appendectomy were prospectively included before (n = 21) and after (n = 17) the training. All demographic and perioperative data were prospectively collected from their medical records, and time taken from admission to management was measured. RESULTS: All residents had performed less than 10 LAPP as primary operator. Pre- and intraoperative data were comparable between pretraining and post-training patients. Times to liquid and solid diet were significantly reduced after training [7 h (2-20) vs. 4 (4-6); P = 0.004, and 17 h (4-48) vs. 6 (4-24); P = 0.005] without changing post-operative morbidity [4 (19%) vs. 0 (0); P = 0.11] and length of stay [48 h (30-264) vs. 44 (21-145); P = 0.22]. CONCLUSIONS: CPA training is feasible in abdominal surgery. In the current study, it improved patients' management in terms of earlier oral intake.
