摘要

Primary banded Roux-en-Y gastric bypass is performed routinely in many countries worldwide to add more restriction to bariatric procedures and consequently to prevent dilatation of the gastroenterostomy and weight regain. However, in Germany, banded gastric bypass is mainly performed as a revisional procedure for unfavorable post-bariatric results. To investigate the short- and midterm results of revisional banded gastric bypass, 47 patients were included in this retrospective, single-center study. Two years after surgery, a moderate additional total weight loss of 14.7% was observed. In subgroup analysis, patients who underwent revisional surgery due to insufficient weight loss dropped 10.52 BMI points. Patients that required banding for non-weight-related issues, like dumping syndrome, did not experience significant weight loss. Interestingly, revisional banded gastric bypass showed relatively high morbidity and a high band explantation rate of 42.6%, especially with lower ring circumferences. Therefore, adequate patient selection is crucial for revisional banded gastric bypass and small ring circumferences should be strictly avoided.
