Bowel obstruction is a known complication of Roux-en-Y gastric bypass. It can be caused by adhesions, internal hernia, incarcerated ventral hernia, or intussusception. Sometimes the underlying cause may be unusual. These 2 case reports describe patients who underwent laparoscopic Roux-en-Y gastric bypass and whose postoperative courses were complicated by small-bowel obstruction due to phytobezoars in the ileum, distal to the jejunojejunal anastomosis. We reviewed the literature by using PubMed and Medline for causes, pathogenesis, classifications, diagnosis, and management.

The rising prevalence of obesity has led to an increase in bariatric procedures, with laparoscopic Roux-en-Y gastric bypass (LRYGB) being one of the most commonly performed surgeries due to its efficacy and safety. However, internal hernia (IH) remains a significant complication post-LRYGB. The debate over preventive closure of mesenteric defects (MD) during LRYGB continues, with no consensus on the optimal technique.

Introduction: Strategies to address suboptimal weight loss after Roux-en-Y gastric bypass (RYGB) can be developed if at-risk patients are identified in advance. This study aimed to build a pre-surgery prediction nomogram for early prediction of insufficient weight loss (IWL) or weight regain (WR) after bariatric surgery in Chinese patients.
Methods: In this retrospective study, 187 patients with obesity and type 2 diabetes who underwent laparoscopic RYGB were followed yearly for 3 years.

Medical Department, Ålesund Hospital, Møre Og Romsdal Hospital Trust, 6026, Ålesund, Norway.
Background: Several studies have documented a beneficial short-term effect on lipid profile after Roux-en-Y gastric bypass (RYGB), but there is limited data on long-term changes.
Objectives: To describe long-term (> 10 years) changes in lipid profile after RYGB and to explore the relationship of lipid changes to changes in weight and baseline and demographic parameters.
Methods: The BAROBS study is a prospective observational study post RYGB conducted at three different hospitals.

Introduction: Glioblastomas (GBM) are aggressive tumors that make up about 7% of central nervous system tumors in children. Spinal GBMs (sGBMs) are extremely rare, accounting for less than 1% of pediatric spinal tumors. sGBMs are difficult to treat due to their infiltrative nature and cause significant morbidity.

Objective: To measure concentrations of tenofovir diphosphate (TFV-DP) in dried blood spots (DBS) among individuals taking tenofovir disoproxil fumarate plus emtricitabine (TDF/FTC) or tenofovir alafenamide plus emtricitabine (TAF/FTC) who were scheduled to undergo or had already undergone bariatric surgery.
Methods: We enrolled pre-exposure prophylaxis (PrEP) users attending clinics in Toronto or Ottawa who were undergoing or had undergone bariatric surgery. After participants completed a minimum of 7 days of consecutive PrEP dosing, we collected DBS samples immediately before they administered their next daily dose of PrEP.
