To evaluate the association between glucagon-like peptide 1 (GLP-1) secretion and the long-term (>2 years) outcome of type 2 diabetes mellitus (T2DM) after Roux-en-Y gastric bypass (RYGBP). ⋯ Our data show that in subjects with T2DM an enhanced GLP-1 response to meal intake is not sufficient to maintain normal glucose tolerance in the long term after RYGBP. Our data suggest that β-cell function is a key determinant of the long-term remission of T2DM after this bariatric surgery technique.

The aim of this study was to investigate in a retrospective setting the patients' profile and results of those undergoing surgery for hepatocellular carcinoma (HCC) in high-volume surgical centers throughout the world. ⋯ This large multicentric survey shows that surgery is in current practice widely applied among patients with multinodular, large, and macrovascular invasive HCC, providing acceptable short- and long-term results and justifying an update of the EASL/AASLD therapeutic guidelines in this sense.

To review our current understanding of the epidemiology and pathogenesis of vein graft failure (VGF), give an overview of current preventive and interventional measures, and explore strategies that may improve vein graft patency. ⋯ Despite advances in management, VGF remains one of the leading causes of poor in-hospital and long-term outcomes after coronary artery bypass graft surgery. New developments in VGF prevention such as gene therapy, external graft support, fully tissue-engineered grafts, hybrid grafts, and synthetic conduits are promising but unproven. Future efforts to reduce VGF require a multidisciplinary approach with a primary focus on prevention.

Survival and prognostic factors were analyzed in 315 patients with esophageal cancer undergoing thoracoscopic-assisted esophagectomy (TAE). The 5-year survival rate of 57.8% was satisfactory, indicating the oncological feasibility of TAE. Perioperative outcomes affected overall survival in the whole cohort but not in the subgroup treated with 2 endoscopic stages. ⋯ TAE was oncologically feasible. Perioperative factors affected survival in the whole cohort, but did not in the THLE subgroup. However, the reduced perioperative factor effect in this subgroup would be small because the survival rates of the 2 surgical approaches were equal.

Multicenter Study
Liver transplantation for neuroendocrine tumors in Europe-results and trends in patient selection: a 213-case European liver transplant registry study.
The purpose of this study was to assess outcomes and indications in a large cohort of patients who underwent liver transplantation (LT) for liver metastases (LM) from neuroendocrine tumors (NET) over a 27-year period. ⋯ LT is an effective treatment of unresectable LM from NET. Patient selection based on the aforementioned predictors can achieve a 5-year OS between 60% and 80%. However, use of overly restrictive criteria may deny LT to some patients who could benefit. Optimal timing for LT in patients with stable versus progressive disease remains unclear.
