Introduction:
Several studies have shown the positive effect on weight loss of the banded Roux-en-Y gastric bypass (BRYGB). Thus far, studies describing the 10-year post-operative results are scarce. Therefore, the aim of this study was to describe the weight loss results, effect on associated medical problems, and complication rates during 10 years of follow-up after BRYGB.
Method:
Data were collected from patients who underwent laparoscopic BRYGB with a non-adjustable silicone gastric ring between January 2011 and March 2013. All patients were included when found to be eligible according to the IFSO criteria.
Results:
One hundred forty-nine patients were included, 110 received a primary BRYGB and 39 received a conversional BRYGB. The primary BRYGB group consisted of 68% female patients with a mean BMI of 44.5 kg/m2 and a mean age of 46 years old. The conversional group consisted of 77% females and had a mean BMI of 34.8 kg/m2 and a mean age of 48 years. At 10-year follow-up, 67.1% of the data was available. Ten-year post-operative 30% total weight loss was seen in the primary group, and 7% in the conversional group. In 10 years, 23% of the patients had complications of which half were ring-related.
Conclusion:
The addition of a silicon ring to the Roux-en-Y gastric bypass may result in substantial and stable weight loss maintenance 10 years post-operative. Furthermore, the number of patients with long-term complications was low and the number of associated medical problems was significantly reduced.
