Eight cases with intestinal anomalies in rotation and position were encountered by routine gastrointestinal examination. They are a case of typical non-rotation, so-called mesenterium communae, a rare case of situs inversus totalis combined with mesenterium communae, 4 cases of mal rotation, and 2 cases of normal rotation with incomplete fixation of the descending colon to the posterior abdominal wall. Normally the umbilical loop rotates counterclockwise around the superior mesenteric artery during intrauterine life, and anomalous position of the intestine is caused by abnormal rotation and fixation of the umbilical loop. In the case of non-rotation, the duodenojejunal flexure is absent and the small intestine occupies the right abdomen and the colon the left. In the case of situs inversus totalis combined with non-rotation, the position of the viscera is a mirror image of that in the former case. The celiac and the superior mesenteric arteriograms disclosed some anomalies of vascular distribution. In the typical case of malrotation, the ileocecal position is found in the right upper abdomen. Clinically some cases have undefinite abdominal complaints which may be attributed to anomalous intestinal position, though the others are asymptomatic. These anomalies are clinically important because of the predisposition to intestinal volyulus or obstruction.
