Abstract

Peritoneal encapsulation is a rare congenital malformation in which the small bowel is contained within an accessory peritoneal sac. This sac is bounded by the omentum and mesocolon. The small bowel emerges by way of a small aperture. Peritoneal encapsulation is probably a developmental abnormality and is not associated with malrotation. Forteen cases of peritoneal encapsulation were reported in the literature and the majority of the cases showed intermittent abdominal pain. Only two cases presented acute intestinal obstruction. We report a case of peritoneal encapsulation observed in a 22-year-old female who was admitted due to lower abdominal pain. Plain abdominal radiography showed generalized air-fluid levels and a typical mechanical obstruction. The patient received complete excision of accessory peritoneal sac and has been in good condition.
