Comparative StudyEffect of primary versus revisional Roux-en-Y gastric bypass: inferior weight loss of revisional surgery after gastric banding.
Laparoscopic adjustable gastric banding is a popular and effective restrictive bariatric procedure. However, with longer follow-up, it has become clear that a considerable number of patients require revisional surgery, of which Roux-en-Y gastric bypass (RYGB) is the most commonly performed procedure. Studies that compared the outcomes of primary RYGB and revisional RYGB have not been conclusive. Our objective was to determine whether significant differences exist in the 1-year outcomes between primary RYGB (prim-RYGB) and revisional RYGB after laparoscopic adjustable gastric banding (rev-RYGB) at a major training hospital in The Netherlands. ⋯ rev-RYGB is a safe procedure with outcomes similar to those of prim-RYGB in terms of complication rate, hospitalization time, and effect on co-morbidity. Weight loss, however, was significantly less after rev-RYGB than after prim-RYGB.

Practice GuidelineClinical practice guidelines for the perioperative nutritional, metabolic, and nonsurgical support of the bariatric surgery patient--2013 update: cosponsored by American Association of Clinical Endocrinologists, the Obesity Society, and American Society for Metabolic & Bariatric Surgery.
The development of these updated guidelines was commissioned by the AACE, TOS, and ASMBS Board of Directors and adheres to the AACE 2010 protocol for standardized production of clinical practice guidelines (CPG). Each recommendation was re-evaluated and updated based on the evidence and subjective factors per protocol. Examples of expanded topics in this update include: the roles of sleeve gastrectomy, bariatric surgery in patients with type-2 diabetes, bariatric surgery for patients with mild obesity, copper deficiency, informed consent, and behavioral issues. ⋯ These updated guidelines reflect recent additions to the evidence base. Bariatric surgery remains a safe and effective intervention for select patients with obesity. A team approach to perioperative care is mandatory with special attention to nutritional and metabolic issues.

Obesity is a risk factor for developing chronic kidney disease (CKD) that may be improved with bariatric surgical weight reduction. The objective of this study was to investigate changes in the glomerular filtration rate (GFR) in severely obese patients 1 year after bariatric surgery. ⋯ Abnormal renal function was common in severely obese patients. Bariatric surgery-induced weight loss had positive effects on renal function at 1 year after surgery.

Risk factors for acute respiratory failure in bariatric surgery: data from the Nationwide Inpatient Sample, 2006-2008.
Acute respiratory failure (ARF) can be a life-threatening postoperative complication after bariatric surgery and is defined as the presence of acute respiratory distress or pulmonary insufficiency. We sought to identify predictors of ARF in patients who underwent bariatric surgery. ⋯ We identified multiple risk factors that have an effect on the development of acute respiratory failure after bariatric surgery. Surgeons should consider these factors in surgical decision-making and inform patients of their risk of this potentially life-threatening complication.

Proposal for a bariatric mortality risk classification system for patients undergoing bariatric surgery.
An obesity surgery mortality risk score derived from a single clinical series can be used to stratify the mortality risk of patients undergoing gastric bypass. However, such a scoring system does not take into account 2 important factors in contemporary bariatric surgery--increased use of the laparoscopic approach and laparoscopic adjustable gastric banding. The present study analyzed the preoperative factors that might predict in-hospital mortality after bariatric surgery using data from academic medical centers and proposes a classification system for predicting mortality. ⋯ Within the context of academic centers, the mortality after bariatric surgery has decreased substantially since 2002, with an increase in the use of the laparoscopic technique and laparoscopic gastric banding. A bariatric mortality risk classification system was developed to stratify mortality, given the limits of this database, which does not include the body mass index and underestimates the incidence of sleep apnea. It might be useful to aid surgeons in surgical decision-making, to inform patients of their risks, and for quality improvement reporting purposes.
