Role of routine intraoperative endoscopy in laparoscopic bariatric surgery.

BACKGROUND: Laparoscopic bariatric surgery is a challenging procedure with a high risk of technical misadventures that may increase postoperative morbidity. Routine intraoperative endoscopy may reduce postoperative morbidity. This article reviews our 6-year experience.
METHODS: From April 1995 to September 2001, we performed 825 laparoscopic bariatric procedures: 743 roux gastric bypasses, 55 vertical banded gastroplasties, 18 laparoscopic adjustable gastric bands, and 9 gastric pacemakers. All the patients underwent flexible endoscopy by the primary surgeon at completion of the operation to assess for technical errors.
RESULTS: The 34 intraoperative technical errors (4.1%) identified included 29 suture and staple line leaks, 2 bougie perforations, 2 inadvertent stoma closures secondary to the suture line, and 1 mucosal perforation in a gastric pacemaker. All the errors were successfully repaired laparoscopically at the time of the procedure. Three leaks occurred postoperative (0.36%): 1 in the 34 repaired errors (2.9%) and 2 in the remaining 791 patients (0.25%).
CONCLUSIONS: Routine intraoperative endoscopy identified 34 correctable technical errors in a series of 825 laparoscopic bariatric procedures. Of these, 33 (97%) were repaired successfully, which reduced postoperative morbidity.
