Ten Years Experience of Banded Gastric Bypass: Does It Make a Difference?

Abstract

Many surgeons support some sort of restriction of the gastric pouch outlet by placing a ring around the gastric reservoir. Previous studies have shown positive results of banded gastric bypass (BGBP); however, there are not many comparative long-term studies to assess the real advantage of placing a ring during gastric bypass (GBP) surgery. This study aims to evaluate the long-term outcome of patients subjected to BGBP and nonbanded GBP procedures. We studied 260 retrospective, nonrandomized obese patients who underwent BGBP and 218 patients without the ring (i.e., GBP). They were followed up for 10 years, and the following parameters were evaluated: excess weight loss (EWL), quality of life (QOL), food tolerance, and correction of comorbidities. The study was approved by the Committee on Ethics, and all the patients gave their informed consent. There is a significant difference in %EWL from the third year until the tenth year of observation, with the proportion being 82% in BGBP versus 63% in nonbanded GBP patients at the end of the study. Although there was some increased intolerance to food intake in the BGBP patients, this was not felt to reduce the QOL. The outcome in terms of comorbidities was not conclusive. There is a clear advantage in terms of %EWL in the BGBP patients. No differences in QOL were found in both groups. Further, selecting the right type of material and the right size of the ring is important to improve results and avoid complications.
