Multicenter Study Comparative StudyComparison between circular- and linear-stapled gastrojejunostomy in laparoscopic Roux-en-Y gastric bypass--a cohort from the Scandinavian Obesity Registry.
Although laparoscopic Roux-en-Y gastric bypass (LRYGB) is a common bariatric procedure worldwide, no consensus on the optimal technique for the gastrojejunostomy (GJ) has been reached. Circular stapling (CS) immediately results in a GJ of standardized width, whereas linear stapling (LS) requires a technically challenging closure of the stapler defect. The aim was to study differences in outcomes between CS and LS. ⋯ CS was found to be associated with disadvantages regarding operative time, hospital stay, and postoperative complications compared with LS.

Multicenter Study Observational StudyPreoperative factors and 3-year weight change in the Longitudinal Assessment of Bariatric Surgery (LABS) consortium.
Limited data guide the prediction of weight loss success or failure after bariatric surgery according to presurgery factors. There is significant variation in weight change after bariatric surgery and much interest in identifying preoperative factors that may contribute to these differences. This report evaluates the associations of a comprehensive set of baseline factors and 3-year weight change. ⋯ Few baseline variables were associated with 3-year weight change and the effects were small. These results indicate that baseline variables have limited predictive value for an individual's chance of a successful weight loss outcome after bariatric surgery.

Multicenter StudyThe effect of national hospital accreditation in bariatric surgery on perioperative outcomes and long-term mortality.
Controversy exists regarding the relevance of Center of Excellence accreditation to bariatric surgery outcomes. The objective of this study was to evaluate the impact of national hospital accreditation on perioperative and long-term outcomes following bariatric surgery. ⋯ In New York State, bariatric hospital accreditation improved patient outcomes as compared to unaccredited hospitals and within the same hospital compared to preaccreditation. Significant changes were identified for some underserved at-risk populations. Measures to ensure equitable health care for at-risk populations following institutional accreditation are imperative.

Multicenter StudyEffect of perioperative management on short-term outcomes after sleeve gastrectomy: a 600-patient single-center cohort study.
Reports on the postoperative outcomes of sleeve gastrectomy (SG) have only been from small, single-center series and meta-analyses of studies with variable SG management. The objective of this study was to evaluate post-SG outcomes in a specialized bariatric surgery center with a routinely performed standardized procedure. ⋯ In a specialist bariatric surgery center, SG had an acceptable complication rate. Modifications in the perioperative management of SG were associated with a shorter mean operating time and hospital stay and did not increase the major complication or gastric fistula rates.

Multicenter StudyAortic injuries during laparoscopic gastric bypass for morbid obesity in Sweden 2009-2010: a nationwide survey.
In Sweden, bariatric surgery has increased more than tenfold in the past decade, from 700 to 8,600 procedures annually, and laparoscopic gastric bypass (LRYGB) dominates (92% of all procedures). This expansion makes safety issues crucial. The aim of this nationwide survey was to identify aortic injuries in LRYGB. ⋯ Aortic injury is a rare but serious complication in laparoscopic gastric bypass. In this survey, optical trocars constructed to reduce the risk of intraabdominal damage had been used in all 5 cases.
