A Challenging Case of Ileosigmoid Knotting in an Elderly

Ileosigmoid knotting (ISK) is one of the rare causes of acute intestinal obstruction, which has a rapid course for forming gangrene. ISK is considered a variant of sigmoid volvulus, which otherwise is called compound volvulus. The difficulty in ISK diagnoses is owing to its rarity, uncommon presentation, and non-specific radiological findings. The physiological status of the patient and intraoperative findings are the key factors in deciding the operative procedure of choice. Herein the author describes a rare case of ISK in a 70-year-old man with gangrenous ileum and sigmoid colon, which were treated successfully with resection and double stoma.
