Laparoscopic adjustable gastric banding with truncal vagotomy versus laparoscopic adjustable gastric banding alone: interim results of a prospective randomized trial

A total of 50 patients were entered into the study. No mortality resulted, and no conversion to laparotomy was needed. Neither group had any intra- or postoperative complications. The mean weight, body mass index, and percentage of excess weight loss were not significantly different statistically between the 2 groups at 12 or 18 months after surgery (P = NS). At 6 months of follow-up, band adjustment was not required in 10 (50%) of 20 patients with LGBTV compared with 5 (20%) of 25 patients with LGB alone (P = .034). At 12 months, 7 (35%) of 20 LGBTV patients and 2 (8%) of 25 LGB patients still did not require band adjustment (P = .024). Conclusion: The results of our study have shown that adding TV to LGB does not cause specific morbidity or mortality compared with LGB alone. During the first postoperative year, the addition of TV to LGB decreased the number of patients requiring band adjustments.
