Abstract
Background Ileo-ileal knotting was first described by Riverius in the 16th century and by Rokitansky in 1836. It is one
of the rare causes of acute abdominal pain which mandates urgent surgical treatment. Preoperative investigations are
usually nonspecific and high index of suspicion.
Case presentation A 27-year- old male was admitted to Gondar University hospital with a preliminary diagnosis of
intussusception and underwent emergency open laparotomy. Intraoperatively a small intestine gangrene caused by
an ileo-ileal knot was found. Resection of the gangrenous segment followed by ileo-transverse colon anastomosis
was done. Post- operative course was smooth and he was discharged improved.
Conclusion Ileo-ileal knot should be highlighted as a rare cause of acute small bowel obstruction. that necessitates
immediate surgical intervention, particularly in resource limited setups, and complications should be considered in
the perioperative period.
