Background:
The increased incidence of morbid obesity has resulted in an increase in bariatric surgery. The gastrojejunostomy performed during Roux-en-Y gastric bypass (RYGBP) operations has technical variability with different outcomes and complication-rates immediate postoperatively and at long-term follow-up.
Methods:
Between Jan 2000 and Feb 2005, 350 laparoscopic RYGBP procedures were performed. We present our immediate and follow-up rate of complications with total intraabdominal gastrojejunostomy, performed with the circular stapler.
Results:
Complications of gastrojejunostomy were detected in 24 patients (6.8%): 3 anastomotic leaks (0.8%); 6 bleeding (1.7%) immediately postoperatively, and 4 stenoses (1.1%), 10 ulcers (2.8%) and 1 stenosis plus ulcer (0.3%) during long-term follow-up. There was no mortality related to the gastrojejunostomy.
Conclusions:
The gastrojejunostomy with circular stapler is an easily reproducible procedure. The rate of complications has been low. Surgeons who perform laparoscopic RYGBP should have a careful learning curve, and should be aware of the potential complications and their management.
