    Abstract Importance: Clinical trial data sharing holds promise for maximizing the value of clinical research. The International Committee of Medical Journal Editors (ICMJE) adopted a policy promoting data sharing in July 2018.
    Objective: To evaluate the association of the ICMJE data sharing policy with data availability and reproducibility of main conclusions among leading surgical journals.
    Design, setting, and participants: This cross-sectional study, conducted in October 2021, examined randomized clinical trials (RCTs) in 10 leading surgical journals before and after the implementation of the ICMJE data sharing policy in July 2018.
    Exposure: Implementation of the ICMJE data sharing policy.
    Main outcomes and measures: To demonstrate a pre-post increase in data availability from 5% to 25% (α = .05; β = 0.1), 65 RCTs published before and 65 RCTs published after the policy was issued were included, and their data were requested. The primary outcome was data availability (ie, the receipt of sufficient data to enable reanalysis of the primary outcome). When data sharing was available, the primary outcomes reported in the journal articles were reanalyzed to explore reproducibility. The reproducibility features of these studies were detailed.
    Results: Data were available for 2 of 65 RCTs (3.1%) published before the ICMJE policy and for 2 of 65 RCTs (3.1%) published after the policy was issued (odds ratio, 1.00; 95% CI, 0.07-14.19; P > .99). A data sharing statement was observed in 11 of 65 RCTs (16.9%) published after the policy vs none before the policy (risk ratio, 2.20; 95% CI, 1.81-2.68; P = .001). Data obtained for reanalysis (n = 4) were not from RCTs published with a data sharing statement. Of the 4 RCTs with available data, all of them had primary outcomes that were fully reproduced. However, discrepancies or inaccuracies that were not associated with study conclusions were identified in 3 RCTs. These concerned the number of patients included in 1 RCT, the management of missing values in another RCT, and discrepant timing for the principal outcome declared in the study registration and reported in the third RCT.
    Conclusions and relevance: This cross-sectional study suggests that data sharing practices are rare in surgical journals despite the ICMJE policy and that most RCTs published in these journals lack transparency. The results of these studies may not be reproducible by external researchers.

    Abstract Background: Esophagectomy is associated with significant mortality. A better understanding of the causes leading to death may help to reduce mortality. A root cause analysis of mortality after esophagectomy was performed.
    Methods: Root cause analysis was retrospectively applied by an independent expert panel of 4 upper gastrointestinal surgeons and 1 anesthesiologist-intensivist to patients included in the French national multicenter prospective cohort FREGAT between August 2014 and September 2019 who underwent an esophagectomy for cancer and died within 90 days of surgery. A cause-and-effect diagram was used to determine the root causes related to death. Death was classified as potentially preventable or non-preventable.
    Results: Among the 1,040 patients included in the FREGAT cohort, 70 (6.7%) patients (male: 81%, median age 68 [62-72] years) from 17 centers were included. Death was potentially preventable in 37 patients (53%). Root causes independently associated with preventable death were inappropriate indication (odds ratio 35.16 [2.50-494.39]; P = .008), patient characteristics (odds ratio 5.15 [1.19-22.35]; P = .029), unexpected intraoperative findings (odds ratio 18.99 [1.07-335.55]; P = .045), and delay in diagnosis of a complication (odds ratio 98.10 [6.24-1,541.04]; P = .001). Delay in treatment of a complication was found only in preventable deaths (28 [76%] vs 0; P < .001). National guidelines were less frequently followed (16 [43%] vs 22 [67%]; P = .050) in preventable deaths. The only independent risk factor of preventable death was center volume <26 esophagectomies per year (odds ratio 4.71 [1.55-14.33]; P = .006).
    Conclusions: More than one-half of deaths after esophagectomy were potentially preventable. Better patient selection, early diagnosis, and adequate management of complications through centralization could reduce mortality.

    Abstract In most cases, Roux-en-Y gastric bypass (RYGBP) is an efficient intervention to lose weight, change eating behavior and improve metabolic outcomes in obese patients. We hypothesized that weight loss induced by RYGBP in obese Yucatan minipigs would induce specific modifications of the gut–brain axis and neurocognitive responses to oral sucrose stimulation in relationship with food intake control. An integrative study was performed after SHAM (n = 8) or RYGBP (n = 8) surgery to disentangle the physiological, metabolic and neurocognitive mechanisms of RYGBP. BOLD fMRI responses to sucrose stimulations at different concentrations, brain mRNA expression, cecal microbiota, and plasma metabolomics were explored 4 months after surgery and integrated with WGCNA analysis. We showed that weight loss induced by RYGBP or SHAM modulated differently the frontostriatal responses to oral sucrose stimulation, suggesting a different hedonic treatment and inhibitory control related to palatable food after RYGBP. The expression of brain genes involved in the serotoninergic and cannabinoid systems were impacted by RYGBP. Cecal microbiota was deeply modified and many metabolite features were differentially increased in RYGBP. Data integration with WGCNA identified interactions between key drivers of OTUs and metabolites features linked to RYGBP. This longitudinal study in the obese minipig model illustrates with a systemic and integrative analysis the mid-term consequences of RYGBP on brain mRNA expression, cecal microbiota and plasma metabolites. We confirmed the impact of RYGBP on functional brain responses related to food reward, hedonic evaluation and inhibitory control, which are key factors for the success of anti-obesity therapy and weight loss maintenance.

    Abstract The impact of body composition (BC) on the prognosis of resected intrahepatic cholangiocarcinoma (ICC) has been poorly studied. Aims: i) to evaluate the prevalence of low muscle mass (MM) in patients; ii) to assess the impact of BC on patient overall survival (OS) and disease-free survival (DFS), and iii) on the incidence of postoperative complications. All consecutive patients who underwent liver resection for ICC between 2004 and 2016 and who had preoperative CT scans were included. Ninety-three patients were included. Sixty percent (55/91) had low total MM. On multivariable analysis, high visceral fat (HR 2.48, CI95% [1.63; 3.77], p < 0.0001), nodules >1 (HR 3.15 [1.67; 5.93], p = 0.0004), involvement adjacent organ (HR 6.67 [1.88; 23.69], p = 0.003), and postoperative sepsis (HR 3.04 [1.54; 5.99], p = 0.0013) were independently associated with OS. High visceral fat (HR 2.10 [1.31; 3.38], p = 0.002], nodules >1 (HR 3.01, [1.49; 6.10], p = 0.002), postoperative sepsis (HR 5.16 [2.24; 11.89], p = 0.0001), ASA score (p = 0.02) and perineural invasion (HR 3.30 [1.62; 6.76], p = 0.001) were independently associated with lower DFS. Conclusion: 60% of ICC patients had low MM before surgery. High visceral fat, but not muscle mass, was an independent prognostic factor for poor OS and DFS in European patients with resected ICC.

    Abstract Background: Modified Appleby procedure could be indicated in stage III locally advanced body pancreatic ductal adenocarcinoma (PDAC) involving the celiac axis after neoadjuvant treatment.
    Patients and methods: We report the case of a 38-year-old woman presenting a tumor arising from the body of the pancreas, involving the celiac trunk with the common hepatic artery and having contact with the anterior surface of the superior mesenteric artery. A fine-needle aspirate biopsy confirmed the diagnosis of PADC. Eight cycles of FOLFIRINOX followed by chemoradiotherapy (50.4 Gy) were conducted. After 6 months, the CA19-9 levels were normalized, and the tumor remained stable without local growth or distant metastasis. To reduce the risk of ischemia-related complications and develop the pancreaticoduodenal arcades, a preoperative embolization of the common hepatic artery was performed. Then, surgical resection was considered 4 weeks after embolization.
    Results: The patient underwent a modified Appleby procedure including distal splenopancreatectomy with en bloc celiac axis resection combined with lateral portal vein resection. Venous reconstruction was carried out using peritoneal patch.1 Pathologic evaluation revealed a 2.5-cm PDAC with negative resection margins. Postoperative course was marked by acute ischemic cholecystitis requiring reoperation at postoperative day 3. The treatment was completed with four cycles of FOLFIRINOX, and she was free of disease 6 months after surgery.
    Conclusions: Nowadays, modified Appleby procedure is more frequently performed due to improvements in responses to chemotherapy and radiotherapy which have led to better local control and more aggressive approaches in highly selected patients.

    Abstract Summary: Postoperative tracheoesophageal or bronchoesophageal fistulas represent a major surgical challenge. The authors report the description of an original perforator-based intercostal artery muscle flap, aiming to cover all types of intrathoracic fistulas, from any location, in difficult cases such as postoperative fistulas after esophagectomy in an irradiated field. Between June of 2016 and January of 2019, eight male patients were treated with a perforator-based intercostal artery muscle flap. All had previous surgery for esophageal cancer and developed a tracheoesophageal or bronchoesophageal fistula during the perioperative course. The mean patient age was 55.9 ± 8.8 years. All patients received neoadjuvant chemotherapy and seven received neoadjuvant radiation therapy. A perforator-based intercostal artery muscle flap, with a mean skin paddle size of 9.86 × 5 cm, was harvested. The median operative time was 426.50 minutes. The tracheoesophageal or bronchoesophageal fistula was successfully and definitively occluded in three patients; two patients experienced recurrence; and one patient underwent re operation. At 1 year, five patients were alive (62.5 percent), and among them, three (37.5 percent) were free from any intrathoracic complications. Three patients died, because of massive digestive bleeding, mesenteric ischemia, and multiorgan failure, respectively. The perforator-based intercostal artery muscle flap, like the Taylor flap in abdominoperineal reconstruction, could become a workhorse flap for all intrathoracic reconstructions, as it can always be harvested, even if a previous thoracotomy has ruined most of the options. This surgical technique, easily feasible, reliable, and reproducible, became our first option for all postoperative tracheoesophageal or bronchoesophageal fistula patients during the postoperative course following esophagectomy.

    Abstract Background: Bariatric surgery has increased the number of patients requiring medial thighplasty after massive weight loss. However, despite the various complications, the procedure improves quality of life. The authors report postoperative complications of vertical J-shaped medial thigh lift in a series of patients and identify preoperative risk factors.
    Methods: For almost 5 years, the details of all J medial thighplasties performed by a single surgeon were recorded; detailed medical records were also available. Complications can be major (e.g., need for early surgical revision or readmission) or minor (delayed wound healing).
    Results: During the study period, 94 patients were treated and only minor complications were recorded (42.5 percent). On multivariate analysis, older age (OR, 1.05; 95 percent CI, 1.01 to 1.10) and a body mass index greater than or equal to 30 kg/m2 (OR, 2.82; 95 percent CI, 1.10 to 7.22) were independent risk factors for postoperative complications.
    Conclusions: As with other postbariatric operations, medial thighplasty is associated with significant morbidity, but the risk thereof can be easily established and managed. Specific algorithms for determining the risk of postoperative complications based on age and body mass index are needed to guide preoperative discussions with patients and perform patient selection.
