Abstract
The authors experienced a case of reversed malrotation of intestinal tract which was discovered unexpectedly during the operation for multiple colonic polyps. The patient was sixty-year-old female who was previously healthy until 8 months before the operation, when she developed tenesmus and constipation. She took segmental resection of sigmoid colon due to adenomas with moderate to severe dysplasia. Her right side of the transverse colon was found to be located within the lesser sac, posterior to the stomach, duodenum and superior mesenteric artery. The other part of the colon were in normal position. Because this congenital anomaly is known to be a rare type among the rotational anomaly with few literature, we report a case with probable interpretation.
