Background
This study aims to evaluate results on revision surgery for weight regain after gastric bypass, based on surgical technique and follow-up.
Methods
This study is a retrospective analysis of 29 patients who presented weight regain on follow-up after more than 5 years, divided into four groups according to revision surgery type: group 1 (n = 9) includes patients who underwent an increase in the length of the alimentary limb to 200 cm; group 2 (n = 13) are patients who underwent an increase in the length of the alimentary limb and placing of a silicon ring; group 3 (n = 2) are patients who underwent an increase in the length of the alimentary limb and gastric plication, and group 4 (n = 5) are patients who underwent gastric plication and placing of a silicon ring.
Results
The average preoperative weight before revision surgery was 117.8 kg, and the average postoperative follow-up for revision surgery was 13.7 months. Weight loss after revision surgery was observed in all groups but was greater in patients with longer revisional postoperative follow-up. Patients who underwent placing of a silicon ring presented greater weight loss than those who had had such a band since the original gastric bypass operation.
Conclusions
Data suggest that revision surgery may be a useful tool in achieving weight loss in patients presenting weight regain following gastric bypass, obesity, bariatric surgery, gastric bypass, weight regain, and revision surgery.
