Strangulated intestinal obstruction is one of the most common types of acute abdomen and requires urgent surgical treatment. Herein, we report a very rare case of strangulated intestinal obstruction caused by an ileo-ileal knot. An 80-year-old woman was admitted to our hospital with suspicion of strangulation ileus and underwent emergency laparotomy after investigation by exploratory single-port laparoscopy. During surgery, a small bowel gangrene caused by an ileo-ileal knot was found. The gangrenous segment was resected, and primary anastomosis was performed. Post-operative recovery was uneventful except for a minor wound infection. Our extensive search of the literature found only 7 case reports of ileo-ileal knot including ours. An ileo-ileal knot should be considered in the differential diagnosis of acute intestinal obstruction, because this rare phenomenon requires urgent surgical treatment; and some complications should be considered during or after surgery.
