[Prevention and management of complications after laparoscopic gastric bypass operation]

To investigate the prevention and management of complications after laparoscopic gastric bypass (LRYGB) operation.

Clinical data of 82 cases (9 cases of simple obesity, 55 of obesity complicated with type 2 diabetes, 18 of non-obesity simple type 2 diabetes) undergoing LRYGB in our hospital between May 2010 to May 2013 were retrospectively analyzed. Cause of complication was explored and experience was summarized in order to provide reference to clinical practice.

There was no mortality and re-admission within 30 days after procedures. Nine patients developed complications. Punctural injury occurred in 1 patient(1.2%) and laparotomy surgery was performed to stop bleedind. Hemorrhage was observed in 4 patients(4.9%, one patients had concurrent anastomotic ulcer) and was cured by either gastrolavage with solution of epinephrine and normal saline or cautery under gastroscope. Anastomotic leakage occurred in one patient(1.2%) which was cured by placing nose-gastro tube immediately after diagnosis of leakage and total enteral nutrition for one month. Anastomotic stricture occurred in 1 patient(1.2%), general peritonitis occurred after balloon dilation and laparoscopic repair was performed to repair the perforation due to dilation. Gastroplegia occurred in two patients(2.4%) and was cured after fasting, gastrointestinal decompression, usage of gastrointestinal prokinetic medications and enteral nutrition. All complications were cured at last. BMI of all patients dropped in vary extent after a follow up of 19.0-35.0(29.1±5.4) months.

Complication after LRYGB operation may be prevented by active preoperative preparation, surgical precision, and intensive postoperative care. Even complications occur, the corresponding treatments are effective.
