Left paramesocolic hernia presenting as post appendicectomy abdominal cocoon.

We describe a rare case of left mesocolic hernia presenting as post appendicectomy intestinal obstruction in a girl. Laparotomy confirmed partial peritoneal encapsulation of upper small bowel due to herniation of jejunal loops into the left mesocolic hernia sac. Reduction of contents, resection of the sac and repair of the defect concluded the procedure uneventfully.
