Background: Abdominal cocoon is a rare disease where small intestine is enclosed in a membrane and commonly presents with features of bowel obstruction. Case Reports: We present two cases: one 28 years old male presented with abdominal pain and was diagnosed as abdominal cocoon at laparotomy; and another 81 years old female, a case of sigmoid cancer, was diagnosed at laparotomy as abdominal cocoon. In both cases membrane enclosing small intestine was excised. Histopathology of membrane was reported as fibro-collagenous tissue. Discussion: Abdominal cocoon is a rare entity, and its etiology is poorly understood. In most of cases preoperative diagnosis is not made with certainty despite of advancement in imaging. So, most of cases are diagnosed at laparotomy. Excision of membrane is the definitive treatment of abdominal cocoon. Conclusion: A high index of suspicion is required for diagnosing abdominal cocoon.
