Abstract
OBJECTIVE: Obesity is a growing global health burden which is particularly challenging to manage. Bariatric surgery is considered the most effective means of sustained weight loss, and Roux-en-Y gastric bypass is considered the most effective treatment for morbid obesity. The additional benefit of placing a non-adjustable band to form a banded Roux-en-Y gastric bypass has gained interest as a measure to improve weight loss; however, comparative data are few, and complications can be high. METHODS: We conducted a prospective case-control study of 484 patients aged 18 and over who received either banded Roux-en-Y gastric bypass with a non-adjustable silastic ring or Roux-en-Y gastric bypass. Patients were followed up for five years and evaluated for weight loss, percentage excess weight loss (%EWL), BMI, and band-related complications. RESULTS: No significant difference was detected in %EWL or BMI between BRYGB and RYGB. The mean raw weight loss, %EWL, and BMI for BRYGB verse RYGB were as follows: 27.49 SD (17.11) kg verse 34.46 SD (18.18) kg, 65.7% SD (30%) verse 62.2% SD (37%), and 32.33 SD (6.9) kg/m2 verse 32.43 SD (7.2) kg/m2. A total of 80 (21.7%) patients had the non-adjustable band removed for complications. CONCLUSION: There is little difference in weight-loss results when comparing BRYGB to RYGB and non-adjustable bands may cause significant complications.
