Introduction/Importance:
Peritoneal encapsulation (PE) is a rare congenital anomaly characterised by the presence of an accessory peritoneal membrane which encases part of the small bowel. Typically, this remains asymptomatic, however; in rare cases, a person may present with symptoms suggestive of a small bowel obstruction.
Case Presentation:
Here we present a case of a 58 year old gentleman with congenital PE causing a bowel obstruction which was revealed on commuted tomography scan. He required a laparotomy and excision of the accessory sac.
Clinical Discussion:
Pre-operative diagnosis of PE can be challenging. It can present as a bowel obstruction with unique features including asymmetric distension of the abdomen on clinical exam and cocoon-like cluster of small bowel on imaging.
Conclusion:
Congenital PE is a rare cause of bowel obstruction and should be considered early in patients presenting with symptoms of bowel obstruction without previous abdominal surgery.
