Root cause analysis of mortality after esophagectomy for cancer: a multicenter cohort study from the FREGAT database.

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.

Tumor downstaging after neoadjuvant chemotherapy determines survival after surgery for gastric adenocarcinoma.

Background: Since 2006, surgery combined with perioperative chemotherapy is the standard of care for resectable gastric adenocarcinoma in Europe. Specific effects of neoadjuvant chemotherapy remain unknown. The aim was to evaluate the rate of tumor downstaging and its impact on survival in patients undergoing curative resection after neoadjuvant chemotherapy (NeoCT) for gastric adenocarcinoma.

Circumferential esophageal replacement by a decellularized esophageal matrix in a porcine model.

Background: Tissue engineering is an attractive alternative to conventional esophageal replacement techniques using intra-abdominal organs which are associated with a substantial morbidity. The objective was to evaluate the feasibility of esophageal replacement by an allogenic decellularized esophagus in a porcine model. Secondary objectives were to evaluate the benefit of decellularized esophagus recellularization with autologous bone marrow mesenchymal stromal cells and omental maturation of the decellularized esophagus.

Staged Double Hepatectomy, Double Total Vascular Exclusion, and Double Venous Reconstruction by Peritoneal Patches in One Patient with Colorectal Liver Metastases.

Background: Surgical resection is the best treatment for colorectal liver metastases with good response to chemotherapy and in the absence of extrahepatic disease.1 With the amelioration of surgical technique, primary and recurrent colorectal liver metastases with venous invasion can be resected safely under short total vascular exclusion (TVE), and associated right thoracotomy can have a major benefit if resection at the hepato-caval junction is planned.2 The availability of the peritoneum as an autologous graft for venous reconstruction considerably facilitates the task of the surgeon.

Fistulojejunostomy for Chronic Fistula After Sleeve Gastrectomy.

The most dreadful complication after sleeve gastrectomy (SG) is staple line leak. Its rate varies between 1 and 2%. With the development of interventional endoscopy, its treatment is currently fairly standardized and allows healing in the majority of cases without revisional surgery.

Long-Term Evaluation of Biliary Reflux on Esogastric Mucosae after One-Anastomosis Gastric Bypass and Esojejunostomy in Rats.

Background: One-anastomosis gastric bypass/mini-gastric bypass (OAGB/MGB) remains controversial because it may cause chronic biliary reflux (BR). The risk of developing esogastric cancer due to BR after OAGB/MGB is based on the results of experimental rat studies using esojejunostomy (EJ). The aim of this study was to analyze the potential long-term consequences of BR on the esogastric mucosae in OAGB/MGB-operated rats and to compare these results to those from the use of EJ.
