An Elderly Case of Intestinal Malrotation Causing Midgut Volvulus with Non-specific Bands

Abstract

A 71-year-old woman presented with vomiting. She had not bowel movement for a week An abdominal plain CT scan showed a volvulus of the transverse colon. After an unsuccessful attempt at endoscopic repair, emergency surgery was performed. Upon operation, intestinal malrotation was identified to be non-rotation type. There was no Ladd's band and the transverse colon banded to the sigmoid colon and jejunum. The torsion twisting counterclockwise by 360 degrees was released. Although she had not bloody ascites nor ischemic change in the intestine, she underwent right hemijejunostomy to prevent recurrence. This adult case of intestinal malrotation causing midgut volvulus with non-specific bands is reported due to its rarity in the Japanese literature.
