A case of intestinal obstruction by pseudoenterolith formed after anastomosis of transverse and sigmoidal colon

Abstract

This report presents a case of intestinal obstruction linked to pseudo enterolith in postoperative colon loop.

A 84-years-old female presented with subabdominal pain, and admitted to our hospital under adiagnosis of intestinal obstruction. X-ray examination revealed a gas image from the colon to the small intestine and niveau. Computed tomography showed that a spherical body were present in the lumen of sigmoidal colon. It was approximately 40mm, and calcified. We diagnosed that the spherical body is enterolith, and cause of the intestinal obstruction. Enterolith lithotripsy performed 4times with an endoscope. After lithotripsy, barium enema revealed colon loop, anastomosis of sigmoidal colon and transverse colon. We presume that enterolith formed in this postoperative colon loop.
