About

This study is to investigate the rate of internal hernia after laparoscopic Rox-en-Y gastric bypass when the defects are closed using cyano-acrylate glue.

Full description

Background Internal hernia complicated by bowel obstruction is a well-recognized complication of laparoscopic Roux-en-Y gastric bypass (LRYGB). The present study aims to investigate the role of cyanoacrylate glue in the prevention of internal hernia (IH) after LRYGB and compare it with the open technique of managing mesenteric defects by leaving the mesentery intact without closure of mesenteric defects. Data from six UK hospitals have been involved in this study. Operations were done under the supervision of a single senior consultant surgeon of bariatric surgery.

Methods The prospectively collected data of 813 patients with morbid obesity who underwent LRYGB were retrospectively analyzed. Patients were subdivided into two groups: group I comprising 185 patients who had the mesenteric defects closed with cyanoacrylate glue and group II comprising 628 patients who were managed by the open technique of leaving the mesentery intact without closure of the mesenteric defects.

Enrollment: 928 patients

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

• All patients who underwent antecolic LRYGB without closure of mesenteric defects using cyanoacrylate glue or without closure of the mesenteric defects.

Exclusion criteria

• Open RYGB, laparoscopic converted to open RYGB, laparoscopic retro-colic RYGB, laparoscopic ante-colic RYGB with closure of the defect using sutures or RYGB done for non-bariatric purposes e.g. idiopathic gastroparesis.
