A Case of Sigmoid Colon Perforation due to a Rice Cake

Abstract

A 70-year-old man was seen at our hospital because of abdominal pain and vomiting. Abdominal computed tomography showed a high-density object in the sigmoid colon and a surrounding air-density area.
We performed an emergency operation with a diagnosis of sigmoid colon perforation by a rice cake. Partial sigmoid resection and anastomosis was performed.
At laparotomy, a hard rice cake was incarcerated at the site of perforation of the sigmoid colon, with ulceration in other parts formed by the pressure from the rice cake.
Because I encountered a rare case of sigmoid colon perforation by a rice cake, I report it herein.
