The ileosigmoid knot (ISK) is a rare cause of intestinal obstruction in which the ileum wraps around the base of the sigmoid colon and forms a pseudo-knot of the intestine. Herein, we report a case of 76-year-old female with schizophrenia who presented with pan-peritonitis and shock. A 76-year-old female with shock was brought to our hospital. She had a history of schizophrenia and a yearlong stay in a mental hospital before this admission. She was diagnosed with strangulation ileus by computed tomography (CT). The CT scan specifically showed that a loop of ileum was wrapped around the base of the sigmoid colon in anticlockwise direction, leading to the formation of a knot. The patient underwent emergent laparotomy soon after admission. Gangrenous portions of the ileum and sigmoid colon were resected, and an end-to-end anastomosis with a covering stoma was performed. We report a case of ileosigmoid knot in which the patient had schizophrenia, and discuss the relationship between psychiatric disorder and dietary habits which may be associated with the patient's led to the development of the ISK.
