Some patients may experience inadequate weight loss or weight regain due to gastric pouch dilation after one anastomosis gastric bypass (OAGB). Dilated gastric pouch resizing (GPR) associated with correction of eating behavior was suggested as an option in the management of these patients. Retrospective analysis of 17 consecutives patients who underwent a GPR between 2007 and 2017 was undertaken. At revision, the mean body mass index (BMI) and percentage of total weight loss (%TWL) were 41.5 ± 11 kg/m2 and 15 ± 10, respectively. Overall morbidity rate was 6.7% (n = 1). Two years after revision, the mean BMI and %TWL were 34.1 ± 5 kg/m2 and 31 ± 13, respectively. GPR appeared to be a satisfactory option resulting in mid-term secondary weight loss in well selected patients at the expense of non-negligible morbidity rate.
