Results of descriptive data analyses comparing frequencies of small intestinal lesions, common diagnosis categories, types of small intestinal anastomosis performed, prokinetic drugs administered intra- or postoperatively, and postoperative reflux between the two study cohorts. Chi-square (χ2) test p values comparing these frequencies and total frequencies are shown. Descriptive data are presented as numbers (%)
