Abstract
Abdomen cocoon is a rare disease in which a thick peritoneal membrane wraps the intestine causing the bowel loops to adhere to each other. It may be either primary(idiopathic) or secondary to other causes like previous abdominal surgery. Most patients present with abdominal pain and intestinal obstruction. The condition is usually diagnosed intraoperatively. CASE 1: A 30-year-old male patient presented with abdominal pain and bilious vomiting. The patient had similar previous attacks. Examination showed distension abdominal distension with central tenderness. Plain abdominal X-ray showed multiple air fluid levels. During surgery most of ileum was enclosed by thin membrane with dilated proximal jejunum. Release of the bowel loops was done. The patient was well after surgery and was discharged with no post-operative complications. CASE 2: A 35-year old male presented with chronic right lower quadrant abdominal pain, the past medical and surgical histories were non-relevant. Abdominal examination showed tenderness on deep palpation at the right iliac fossa, abdominal ultrasound and abdominal X-ray were normal. During diagnostic laparoscopy the terminal ileum was enclosed with a thick whitish membrane with dilated proximal ileum. Release of the adhesions was done. The patient was well in the post-operative period and he was discharged home with no post-operative complications.In both cases the biopsy from the membranes showed features of chronic inflammatory process.Abdomen cocoon is one of the rare causes of small bowel obstruction. The bowel adhesions should be opened and nonviable segments resected. Most patients have good long term outcome.
