An alternative technique for creating the gastrojejunostomy in laparoscopic Roux-en-Y gastric bypass: Experience with 28 consecutive patients

Background: This study illustrates our experience in laparoscopic Roux-en-Y gastric bypass (LRYGBP) using a new technique for creating the gastrojejun ostomy. Methods: Between April and November 1999, 28 patients underwent LRYGBP. In the first 10 patients the transoral route with endoscopic guidance was util ized for placement of the anvil in the gastric pouch. A new totally intra-p eritoneal approach was utilized in the next 18 patients, avoiding the trans -oral route. Results: There were 23 women and 5 men with an average age of 36 years (ran ge 24-51). The mean BMI was 47, with range 41-64. Of the patients, 82% had one or more associated co-morbid conditions (hypertension, diabetes, sleep apnea, arthritis). Average operative time in the first 10 patients using th e trans-oral route with endoscopic guidance was 340 minutes (range 240-390 min). The next 18 patients underwent totally intra-peritoneal anvil placeme nt with a 240-minute average operating time (range 150-310 min). There were no open conversions or mortalities, There were 4 complications, including 2 wound infections, one urinary tract infection, and one intra-abdominal ab scess. The two wound infections occurred in the first 10 patients that unde rwent trans-oral introduction of the anvil. Conclusions: LRYGBP was a safe and feasible operation. We believe that our technique is easily reproducible, avoiding the trans-oral route for introdu cing the anvil. This technique may also decrease operative time and possibl y the incidence of wound infections, although we are still in the learning curve and final conclusions cannot be made.
