Impact of Laparoscopic Banded Gastric Bypass on Weight Loss Surgery Outcomes: 5 Years' Experience

Objective Evaluate 5-year outcomes of banded gastric bypass (BRYGB) as a primary and conversion bariatric procedure. Methods Retrospective review of BRYGB between January 2011and March 2013. Outcomes included percentage of total weight loss (%TWL), weight loss maintenance, and band-related complications. Results One hundred forty-two patients underwent BRYGB, 106 primary and 36 conversions. Indications for conversion to BRYGB were complications of the primary procedure (n = 19), insufficient weight loss (n = 5), and weight regain (n = 12). In the primary group, mean preoperative BMI was 44.8 kg/m(2) (+/- 6.9 kg/m(2)). Compared with preoperative weight, mean %TWL was 33.9% (n = 95), 34.1% (n = 82), 34.0% (n = 70), 33.9% (n = 62), and 31.8% (n = 75) after 1, 2, 3, 4, and 5 years, respectively. In conversions secondary to failed primary procedure (insufficient WL and weight regain), mean preoperative BMI was 40.8 kg/m(2) (+/- 6.01 kg/m(2)). Despite one patient gaining weight, mean %TWL was 25.7% (n = 13), 28% (n = 11), 23.9% (n = 8), 18.3% (n = 8), and 15.1% (n = 12) after 1, 2, 3, 4, and 5 years, respectively. In conversions secondary to primary procedure complications (n = 19), mean preoperative BMI was 28.4 kg/m(2) (+/- 3.5 kg/m(2)). After 1, 2, 3, 4, and 5 years, mean BMI was 28.1 (n = 15), 29 (n = 10), 29.8 (n = 9), 30.6 (n = 10), and 30.9 (n = 12) kg/m(2), respectively. Band-related complications after 5 years: three erosion and five patients complained of persistent dysphagia. One band needed reposition. Perioperative surgical complications: two bleeding, one leakage, one port-site hernia, and one food impaction. Conclusion Banded gastric bypass has good results in terms of weight loss and weight loss maintenance in both primary and conversional bariatric procedures with acceptable incidence of band-related complications.
