Malignancy in bariatric surgery patients: a French multisite cohort.

Background: Bariatric surgery is associated with decreased cancer-related mortality. An indefinite proportion of patients that undergo bariatric surgery have a history of malignancy or will develop cancer. In these patients, weight loss and oncologic evolution needed to be assessed.

Roux-en-Y Gastric Bypass for the Treatment of Leak Following Sleeve Gastrectomy.

Purpose: Laparoscopic sleeve gastrectomy (LSG) is estimated to be its most severe complication. An aggressive management with surgical reconstructive procedures can be proposed in patients in whom all the conservative endoscopic techniques fail. The purpose of the present study was to report our experience with Roux-en-Y gastric bypass (RYGBP) as treatment for the chronic leak after LSG.

Long-Term Effects of Roux-en-Y Gastric Bypass and Sleeve Gastrectomy on Bone Mineral Density: a 4-Year Longitudinal Study.

Introduction: Bone mineral density (BMD) declines in the initial years after bariatric surgery, but long-term skeletal effects are unclear and comparisons between sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are rare.

Design And Methods: An observational longitudinal study of obese patients undergoing SG or RYGB was performed. Whole-body (WB) BMD, along with BMD of the total hip (TH), femoral neck (FN), and lumbar spine (LS), was measured by dual-energy X-ray absorptiometry (DXA) before surgery and yearly thereafter for 4 years.

Laparoscopic Surgery for Recurrent Hiatal Hernia.

Surgical treatment of hiatal hernia (HH) is well standardized. However, recurrence is observed in 15%-60% of cases, and is challenging to manage. The aim of this study was to analyze the causes of surgical failure and provide some guidelines for treatment.
