    Background The optimal surgical procedure for duodenal gastrointestinal stromal tumors (D-GISTs) remains poorly defined. Pancreaticoduodenectomy (PD) allows for a wide resection but is associated with a high morbidity rate. Objectives The aim of this study was to compare the short- and long-term outcomes of PD versus limited resection (LR) for D-GISTs and to evaluate the role of tumor enucleation (EN). Methods In this retrospective European multicenter cohort study, 100 patients who underwent resection for D-GIST between 2001 and 2013 were compared between PD (n = 19) and LR (n = 81). LR included segmental duodenectomy (n = 47), wedge resection (n = 21), or EN (n = 13). The primary objective was to evaluate disease-free survival (DFS) between the groups, while the secondary objectives were to analyze the overall morbidity and mortality, radicality of resection, and 5-year overall survival (OS) and recurrence rates between groups. Furthermore, the short- and long-term outcomes of EN were evaluated. Results Baseline characteristics were comparable between the PD and LR groups, except for a more frequent D2 tumor location in the PD group (68.3% vs. 29.6%; p = 0.016). Postoperative morbidity was higher after PD (68.4% vs. 23.5%; p < 0.001). OS (p = 0.70) and DFS (p = 0.64) were comparable after adjustment for D2 location and adjuvant therapy rate. EN was performed more in American Society of Anesthesiologists (ASA) stage III/IV patients with tumors < 5 cm and was associated with a 5-year OS rate of 84.6%, without any disease recurrences. Conclusions For D-GISTs, LR should be the procedure of choice due to lower morbidity and similar oncological outcomes compared with PD. In selected patients, EN appears to be associated with equivalent short- and long-term outcomes. Based on these results, a surgical treatment algorithm is proposed

    BACKGROUND Whether the benefits of the robotic platform in bariatric surgery translate into superior surgical outcomes remains unclear. The aim of this retrospective study was to establish the 'best possible' outcomes for robotic bariatric surgery and compare them with the established laparoscopic benchmarks. METHODS Benchmark cut-offs were established for consecutive primary robotic bariatric surgery patients of 17 centres across four continents (13 expert centres and 4 learning phase centres) using the 75th percentile of the median outcome values until 90 days after surgery. The benchmark patients had no previous laparotomy, diabetes, sleep apnoea, cardiopathy, renal insufficiency, inflammatory bowel disease, immunosuppression, history of thromboembolic events, BMI greater than 50 kg/m2, or age greater than 65 years. RESULTS A total of 9097 patients were included, who were mainly female (75.5%) and who had a mean(s.d.) age of 44.7(11.5) years and a mean(s.d.) baseline BMI of 44.6(7.7) kg/m2. In expert centres, 13.74% of the 3020 patients who underwent primary robotic Roux-en-Y gastric bypass and 5.9% of the 4078 patients who underwent primary robotic sleeve gastrectomy presented with greater than or equal to one complication within 90 postoperative days. No patient died and 1.1% of patients had adverse events related to the robotic platform. When compared with laparoscopic benchmarks, robotic Roux-en-Y gastric bypass had lower benchmark cut-offs for hospital stay, postoperative bleeding, and marginal ulceration, but the duration of the operation was 42 min longer. For most surgical outcomes, robotic sleeve gastrectomy outperformed laparoscopic sleeve gastrectomy with a comparable duration of the operation. In robotic learning phase centres, outcomes were within the established benchmarks only for low-risk robotic Roux-en-Y gastric bypass. CONCLUSION The newly established benchmarks suggest that robotic bariatric surgery may enhance surgical safety compared with laparoscopic bariatric surgery; however, the duration of the operation for robotic Roux-en-Y gastric bypass is longer

    PURPOSE: Sphincter-preserving surgery for rectal cancer is often associated with low anterior resection syndrome (LARS). The aim of our study was to determine the prevalence of LARS in our institution and identify possible risk factors for LARS. Furthermore, we evaluated which of the LARS symptoms was considered most disabling by patients and whether or not there is an adaptation of the LARS score over time. METHODS: This study includes a prospective database of 100 patients who underwent total or partial mesorectal excision between January 2009 and September 2014. Patients were contacted after a median postoperative time of 38 (5-45) months to determine the LARS score and to identify LARS symptoms that were considered most disabling. Uni- and multivariate regression analysis was performed to identify risk factors for LARS and major LARS. Finally, the LARS score was evaluated over time after restoration of bowel continuity. RESULTS: Out of the 100 patients, 16 had minor LARS (score 21-29) and 51 patients had major LARS (score 30-42). Radiotherapy was an independent risk factor for major LARS (p = 0.04). For the majority of patients with major LARS (22%), fragmentation was considered the most disabling complaint. There was no correlation between interval after restoration of bowel continuity and the severity of the LARS score. CONCLUSIONS: Perioperative radiotherapy is an independent risk factor for major LARS. Fragmentation is considered the most disabling complaint in the majority of patients with major LARS. There is no significant adaptation of the LARS score over time.status: publishe

    Giant Hepatic Carcinoid: A Rare Tumor with a Favorable Prognosis

    Primary hepatic carcinoids are rare tumors that are often diagnosed at a locally advanced stage. Their primary nature can only be ascertained after thorough investigations and long-term follow-up to exclude another primary origin. As with secondary neuroendocrine liver tumors, surgical resection remains the mainstay of therapy. Despite their large size and often central location liver resection is often feasible, offering long-term survival and cure to most patients. In selected patients liver transplantation appears to be a good indication for tumors not amenable to liver resection. An aggressive surgical attitude is therefore warranted. We report a large and unusually fast-growing liver carcinoid that appeared only marginally resectable in a patient who remains free of disease four years after surgery

    International audienceObjective: To evaluate outcomes associated with esophageal perforation (EP) management at a national level and determine predictive factors of 90-day mortality (90dM), failure-to-rescue (FTR), and major morbidity (MM, Clavien-Dindo 3-4). Background: EP remains a challenging clinical emergency. Previous population-based studies showed rates of 90dM up to 38.8% but were outdated or small-sized. Methods: Data from patients admitted to hospitals with EP were extracted from the French medico-administrative database (2012–2021). Etiology, management strategies, and short and long-term outcomes were analyzed. A cutoff value of the annual EP management caseload affecting FTR was determined using the “Chi-squared Automatic Interaction Detector” method. Random effects logistic regression model was performed to assess independent predictors of 90dM, FTR, and MM. Results: Among 4765 patients with EP, 90dM and FTR rates were 28.0% and 19.4%, respectively. Both remained stable during the study period. EP was spontaneous in 68.2%, due to esophageal cancer in 19.7%, iatrogenic postendoscopy in 7.3%, and due to foreign body ingestion in 4.7%. Primary management consisted of surgery (n = 1447,30.4%), endoscopy (n = 590,12.4%), isolated drainage (n = 336,7.0%), and conservative management (n = 2392,50.2%). After multivariate analysis, besides age and comorbidity, esophageal cancer was predictive of both 90dM and FTR. An annual threshold of ≥8 EP managed annually was associated with a reduced 90dM and FTR rate. In France, only some university hospitals fulfilled this condition. Furthermore, primary surgery was associated with a lower 90dDM and FTR rate despite an increase in MM. Conclusions: We provide evidence for the referral of EP to high-volume centers with multidisciplinary expertise. Surgery remains an effective treatment for EP

    Closure of mesenteric defects is associated with a higher incidence of small bowel obstruction due to adhesions after laparoscopic antecolic Roux-en-y gastric bypass: A retrospective cohort study

    INTRODUCTION: Small bowel obstruction (SBO) is a frequent complication after laparoscopic Roux-en-y gastric bypass (LRYGB). OBJECTIVES: We wanted to evaluate the effect of closure of the mesenteric defects on the incidence of SBO and postoperative complications after LRYGB. Furthermore, we wanted to identify possible risk factors for SBO. METHODS: This study was a retrospective cohort study of 1364 patients who underwent a LRYGB between July 2003 and October 2015. Cohort 1 contained 724 patients in whom mesenteric defects were not closed. Cohort 2 contained 640 patients in whom mesenteric defects were closed. Main outcome parameters were the incidence of SBO and postoperative complications as well as potential risk factors for SBO. RESULTS: Closure of the mesenteric defects was associated with a reduction in the incidence of SBO due to internal herniation (4.8% vs. 5.5, p = 0.02) but resulted in a higher incidence of SBO due to postoperative adhesions (4.8% vs. 1.7%, p = 0.004). Multivariate analysis identified smoking as a risk factor for SBO (p = 0.0187). We observed a higher incidence of late postoperative pain in cohort 2 (5.3% vs. 2.1%, p = 0.007). CONCLUSION: Although closure of the mesenteric defects is associated with a lower incidence of SBO due to internal herniation, this effect is countered by a higher incidence of SBO due to postoperative adhesions. Smoking is an independent risk factor for SBO after LRYGB. Closure of the mesenteric defects is associated with a higher incidence of late postoperative pain.status: publishe

    International audienceAvailable data comparing the long-term results of hybrid minimally invasive esophagectomy (HMIE) with that of open esophagectomy are conflicting, with similar or even better results reported for the minimally invasive esophagectomy group.Objective: To evaluate the long-term, 5-year outcomes of HMIE vs open esophagectomy, including overall survival (OS), disease-free survival (DFS), and pattern of disease recurrence, and the potential risk factors associated with these outcomes.Design, setting, and participants: This randomized clinical trial is a post hoc follow-up study that analyzes the results of the open-label Multicentre Randomized Controlled Phase III Trial, which enrolled patients from 13 different centers in France and was conducted from October 26, 2009, to April 4, 2012. Eligible patients were 18 to 75 years of age and were diagnosed with resectable cancer of the middle or lower third of the esophagus. After exclusions, patients were randomized to either the HMIE group or the open esophagectomy group. Data analysis was performed on an intention-to-treat basis from November 19, 2019, to December 4, 2020.Interventions: Hybrid minimally invasive esophagectomy (laparoscopic gastric mobilization with open right thoracotomy) was compared with open esophagectomy.Main outcomes and measures: The primary end points of this follow-up study were 5-year OS and DFS. The secondary end points were the site of disease recurrence and potential risk factors associated with DFS and OS.Results: A total of 207 patients were randomized, of whom 175 were men (85%), and the median (range) age was 61 (23-78) years. The median follow-up duration was 58.2 (95% CI, 56.5-63.8) months. The 5-year OS was 59% (95% CI, 48%-68%) in the HMIE group and 47% (95% CI, 37%-57%) in the open esophagectomy group (hazard ratio [HR], 0.71; 95% CI, 0.48-1.06). The 5-year DFS was 52% (95% CI, 42%-61%) in the HMIE group vs 44% (95% CI, 34%-53%) in the open esophagectomy group (HR, 0.81; 95% CI, 0.55-1.17). No statistically significant difference in recurrence rate or location was found between groups. In a multivariable analysis, major intraoperative and postoperative complications (HR, 2.21; 95% CI, 1.41-3.45; P < .001) and major pulmonary complications (HR, 1.94; 95% CI, 1.21-3.10; P = .005) were identified as risk factors associated with decreased OS. Similarly, multivariable analysis of DFS identified overall intraoperative and postoperative complications (HR, 1.93; 95% CI, 1.28-2.90; P = .002) and major pulmonary complications (HR, 1.85; 95% CI, 1.19-2.86; P = .006) as risk factors.Conclusions and relevance: This study found no difference in long-term survival between the HMIE and open esophagectomy groups. Major postoperative overall complications and pulmonary complications appeared to be independent risk factors in decreased OS and DFS, providing additional evidence that HMIE may be associated with improved oncological results compared with open esophagectomy primarily because of a reduction in postoperative complications
