a Weight evolution curve showing weight in BMI, distinguishing patients with non-closure of the jejunal mesenteric defect from patients operated with closure of the jejunal mesenteric defect. Number of patients at risk (active patients) displayed on top. b BMI 1 and 2 years after primary LRYGB, distinguishing between the whole collective with no IH or no open mesenteric gap vs. all patients with IH or open mesenteric gap event. The boxes show the median and IQR. Single data points represent each individual patient, and the whiskers represent the minimum and maximum range of values. P-values displayed from unpaired t-test. BMI body mass index, SD standard deviation, IH internal hernia. Gaps: open mesenteric gaps at the jejunal mesenteric space or the Petersen space
