Background
Lesser omental transection during gastric bypass for morbid obesity may be associated with postoperative dumping. A survey of postoperative symptoms was performed in patients undergoing laparoscopic Roux-en-Y gastric bypass with transection vs. preservation of the lesser omentum.
Methods
A written questionnaire on dumping symptoms was administered to patients 2 years after laparoscopic Roux-en-Y gastric bypass with or without transection of the lesser omentum. Statistical testing was performed to determine whether the rate of various symptoms was related to the transection of the lesser omentum.
Results
The patients without lesser omental transection had significantly less symptoms than the patients with transection for 11 out of the 17 symptoms that were queried (p < 0.05). Ingestion of sweets was associated with dumping symptoms more frequently in the group of transected patients, and this group also had a lower frequency of sweet eating (p < 0.05).
Conclusion
This study demonstrated that transection of the lesser omentum during laparoscopic–gastric bypass was associated with more postoperative dumping symptoms compared to bypass with preservation of the lesser omentum. This association may be secondary to a partial vagotomy that may occur if the lesser omentum is transected during gastric bypass.
