Ileosigmoid knotting: a rare case of intestinal obstruction with intra-operative finding of type II B ileosigmoid knotting.

Ileosigmoid knotting is one of the rarest emergencies, occurring when the sigmoid colon or ileum wraps around the base of the other, obstructing the flow. It is considered a rare cause of intestinal obstruction. Clinical signs and symptoms are nonspecific, making preoperative diagnosis challenging. Delays in diagnosis and management may lead to bowel necrosis or peritonitis. Here, we present the case of a 37-year-old male who presented with severe abdominal pain, initially misdiagnosed as adhesive bowel obstruction. ISK was diagnosed intra-operatively.
