Closed loop small bowel obstruction due to paracaecal internal herniation: a lesson in rarity.

A 40-year-old man presented to the emergency department of our tertiary hospital with acute abdominal pain since 1 day, which responded to conservative measures initially. On further investigation and abdominal CT, he was diagnosed with closed loop small bowel obstruction with an encapsulated lesion with small bowel loops within, in the right iliac fossa, which was initially missed. On exploration, the patient had a sac in the right iliac fossa (paracaecal incarcerated internal hernia) with distended bowel loops within, the sac was excised after reduction of the contents. Postoperative recovery was uneventful.
