Personality psychopathology: Longitudinal prediction of change in body mass index and weight post-bariatric surgery.

Objective: Bariatric surgery is an effective treatment for obesity, which has been increasing worldwide. However, bariatric surgery causes dramatic physical changes that can cause significant stress. Prior research has found that psychological variables such as personality traits and levels of psychopathology can influence success after bariatric surgery (in terms of body mass index [BMI] reduction and weight loss).

The incidence of complications associated with loop duodeno-ileostomy after single-anastomosis duodenal switch procedures among 1328 patients: a multicenter experience.

Background: The single-anastomosis duodenal switch procedure is a type of duodenal switch that involves a loop anastomosis rather than traditional Roux-en-Y reconstruction. To date, there have been no multicenter studies looking at the complications associated with post-pyloric loop reconstruction.

Objectives: The aim of the study was to report the incidence of complications associated with loop duodeno-ileostomy (DI) following single-anastomosis duodenal switch (SADS) procedures.

Revision to malabsorptive Roux-en-Y gastric bypass (MRNYGBP) provides long-term (10 years) durable weight loss in patients with failed anatomically intact gastric restrictive operations: long-term effectiveness of a malabsorptive Roux-en-Y gastric bypass in salvaging patients with poor weight loss or complications following gastroplasty and adjustable gastric bands.

Background: Twenty percent of gastric restrictive operations require revision. Conversion to Proximal Roux-en-Y gastric bypass (PRNYGBP) is associated with weight regain. Forty-one percent of these fail to achieve a body mass index (BMI) < 35.

Factors affecting morbidity and mortality of Roux-en-Y gastric bypass for clinically severe obesity: an analysis of 1,000 consecutive open cases by a single surgeon.

Introduction: Determinants of perioperative risk for RYGB are not well defined.

Methods: Retrospective analysis of comorbidities was used to evaluate predictors of perioperative risk in 1,000 consecutive patients having open RYGB by univariate analyses and logistic regression.

Results: One hundred forty-six men, 854 women; average age 38.

Initial experience with bariatric surgery in asymptomatic human immunodeficiency virus-infected patients.

Background: Performance of bariatric surgery in patients with human immunodeficiency virus (HIV) infection is controversial. The advent of highly active antiretroviral treatment (HAART) has dramatically reduced the progression of HIV/AIDS, so that these individuals live longer, with nearly undetectable viral loads, and thus may develop obesity and similar obesity-related comorbidity as occurs in the general population. However, HAART also causes lipodystrophy, placing these patients at increased risk for coronary artery disease.
