A Case of Obstructive Colitis Due to Colonic Stenosis After Thyroid Crisis

Abstract

A 44–year–old man was treated for thyroid crisis with a beta blocker, antithyroid drugs, a steroid, and an antipyretic agent for 2 weeks at our hospital. However, he visited the emergency department of our hospital soon after discharge, complaining of abdominal pain. Based on the clinical findings, we made the diagnosis of pan–peritonitis due to obstructive colitis and performed emergency surgery. Intraoperative exploration revealed a stenotic site in the transverse colon and dilatation of the bowel segment on the oral side of the stenosis. We resected the dilated bowel segment and the stenotic site. The postoperative course was uneventful. Histopathological examination revealed an ischemic ulcer at the stenotic site. We encountered a rare case of pan–peritonitis and colonic stenosis caused by an ischemic ulcer of the colon in a patient who had just recovered from a thyroid crisis.
