title: Nonrotation of intestine: a case report.
abstract: Nonrotation of intestine is a congenital abnormality of the midgut which is due to error in the process of rotation. Errors in the 2nd and 3rd stage of rotation can lead to series of abnormalities in the form of malrotation and reversed rotation. As a consequence, the relative position of other organs likes caecum, intestine, meckel's diverticulum changes. This can lead to missing diagnosis of common clinical conditions such as appendicitis. The incidence of nonrotation is 1:500. The congenital abnormality appears to be rare as this could be an incidental abnormality. The symptoms of nonrotation of intestine could be biliary vomiting, recurrent abdominal pain. This could be due to midgut volvulus and intestinal obstruction which happens as a consequence of nonrotation of the intestine. The investigations used for detection and confirmation are CT Imaging. Other associations of nonrotation of the intestine are peritoneal bands. Here we report a case of nonrotation of intestines. In the cadaver of age around 70 years, the small intestinal loops was situated in the right side of the abdominal cavity and large intestine looped on the left side of the abdominal cavity. This was also associated with aberrant position of the caecum and appendix. There were associated peritoneal bands extending from the ascending colon to the left side the abdominal wall. The bands had been removed to visualize the large intestinal loops.
