Shorter circular staple is height associated with lower anastomotic stricture rate in laparoscopic gastric bypass.
Anastomotic stenosis, leak, and hemorrhage are common stapler-related complications of laparoscopic Roux-en-Y gastric bypass. In May 2007, we transitioned from a 25-mm diameter, 4.8-mm-height circular stapler to a 25-mm, 3.5-mm-height circular stapler. We hypothesized that the staple height would be associated with a decreased incidence of perioperative complications. ⋯ In the present study, the use of a 25-mm, 3.5-mm staple height circular stapler was associated with a decreased rate of anastomotic stenosis.

Root cause analysis of internal hernia and Roux limb compression after laparoscopic Roux-en-Y gastric bypass using observational clinical human reliability assessment.
Internal hernia (IH) and Roux limb compression (RC) are recognized complications after retrocolic laparoscopic Roux-en-Y gastric bypass for obesity. The aim of the present study was to systematically identify the surgical technical errors leading to these complications. ⋯ The observational clinical human reliability analysis is a useful method to identify operative failure. For retrocolic, retrogastric laparoscopic Roux-en-Y gastric bypass, a systematic approach for the closure of the transverse mesenteric window might prevent IH complications.
