Multicenter StudyNasogastric tube, temperature probe, and bougie stapling during bariatric surgery: a multicenter survey.
An adverse event in laparoscopic bariatric surgery that has not received much scrutiny involves tube/probe stapling or suturing during gastrectomy or gastroenterostomy. ⋯ Tube/probe complications can occur during laparoscopic bariatric surgery but are seldom reported. However, they can be associated with significant morbidity. The treatment options are dependent on the situation. More importantly, prevention strategies must include constant communication with the anesthesiologist and removal or relocation of a tube before stapling or suturing.

Randomized Controlled Trial Multicenter StudyChanges in postprandial gut hormones after metabolic surgery: a comparison of gastric bypass and sleeve gastrectomy.
Laparoscopic gastric bypass (GB) is reportedly more effective than laparoscopic sleeve gastrectomy (SG) in the treatment of patients with a low body mass index and type 2 diabetes mellitus. However, the mechanism remains speculative. We compared the postprandial gut hormone patterns between patients undergoing laparoscopic GB and laparoscopic SG at 2 years after surgery in a hospital-based, prospective study. ⋯ Both laparoscopic GB and laparoscopic SG have strong hindgut effects after surgery, but GB has a significant duodenal exclusion effect on cholecystokinin. The laparoscopic SG group had lower acyl ghrelin and des-acyl ghrelin levels but greater concentrations of resistin than the laparoscopic GB group.

Multicenter Study Comparative StudyDifferences in outcomes of laparoscopic gastric bypass.
Although several risk factors affecting weight loss outcomes with bariatric procedures have been identified, the effect of age, gender, race, and illness severity on postoperative outcomes of laparoscopic gastric bypass has not been extensively examined. ⋯ The present study identified gender, race, age, and illness severity as risk factors affecting postoperative outcomes after laparoscopic gastric bypass. Male gender and increasing age were overall associated with an increased risk of complications. Significant racial disparities in the outcome measures were observed with blacks having an increased risk of adverse events. Illness severity was shown to adversely affect the surgical outcomes in laparoscopic gastric bypass.

Randomized Controlled Trial Multicenter StudyEffect of staple height on gastrojejunostomy during laparoscopic gastric bypass: a multicenter prospective randomized trial.
Gastrointestinal (GI) bleeding and anastomotic stricture are frequent complications associated with the construction of the gastrojejunostomy during laparoscopic gastric bypass. Staplers with shorter staple height can reduce the rate of postoperative GI hemorrhage. The aim of the present study was to assess the outcomes of patients who had undergone gastric bypass with construction of the gastrojejunostomy using a 25-mm circular stapler with a 3.5- versus 4.8-mm staple height. ⋯ In the present prospective, randomized trial, using a circular stapler with a shorter staple height (3.5 mm) during construction of the gastrojejunostomy, significantly reduced the rate of postoperative anastomotic stricture, with a trend toward a lower rate of GI bleeding from the gastrojejunostomy.

Multicenter Study Comparative StudyComparison of 30-day outcomes after non-LapBand primary and revisional bariatric surgical procedures from the Longitudinal Assessment of Bariatric Surgery study.
The goals were to compare the morbidity and mortality between primary and revisional bariatric surgery and to identify the clinical predictors of adverse outcomes among patients undergoing revisional surgery in the Longitudinal Assessment of Bariatric Surgery consortium. The study was multi-institutional at university hospitals in the United States. ⋯ Revisional surgery was performed without substantial mortality but with a greater incidence of adverse outcomes than was primary bariatric surgery.
