AWAD F, WILLIAM; GARAY M, ÁLVARO; MARTINEZ M, CRISTIÁN  y  YARMUCH G, JULIO. Banded gastric bypass: A ten years evaluation. Rev Chil Cir [online]. 2012, vol.64, n.4, pp.361-367. ISSN 0718-4026.

Background: Placing a ring around the gastric reservoir could improve the weight lowering effects of gastric bypass. Previous studies have shown positive results ofbanded gastric bypass. Aim: To evaluate the long-term outcome of patients subjected to banded gastric bypass (GB) and non-banded GB procedures. Material and Methods: Ten years follow up of260 non randomized obese patients who underwent banded GB and 218 patients in whom the ring was not placed. Excess weight loss (EWL), quality of life (QOL), food tolerance (FT), and correction of comorbidities were assessed. Results: The percentage EWL at ten years of follow up was 82 and 63% among patients subjected to banded and non-banded gastric bypass, respectively (p < 0.01). In three patients with banded GB, there was a migration of the ring to the interior of the stomach. Stenosis of the gastro-jejuno anastomosis occurred in 4 and 0.4% of patients subjected to banded and non-banded GB Perception of quality of life was similar in both groups. The outcome in terms of comorbidities was not conclusive. Conclusions: There is a clear advantage in terms ofEWL among patients subjected to banded GB. No differences in quality oflife were found in both groups
