2 DISCUSSION
Abdominal cocoon disease is a rare abdominal disease characterized by part or all of the organs in the abdominal cavity surrounded by a layer of membrane-like material, shaped like a silkworm cocoon, first reported and named by Foo et al. [1] in 1978. The author admitted this patient because of congenital factors. The patient has had repeated abdominal pain since childhood. It is believed that this patient is a congenital peritoneal malformation, which is caused by the peritoneal variability during embryonic development, and the patient complicated with omentum absent, the sigmoid colon is also wrapped. Most scholars believe that pre-operative diagnosis is difficult, but abdominal CT diagnosis is of great help. The author may diagnose pre-operative CT diagnosis of abdominal cocoon disease. Intraoperative and postoperative medical examinations have further confirmed this disease. The treatment includes conservative medical treatment and surgical treatment. The author of this patient used surgical treatment. During the operation, the remaining small intestine after the removal of the diseased small intestine did not cause short bowel syndrome, so the diseased small intestine was directly removed. The adhesion of the sigmoid colon is not heavy, so only adhesion release is performed.
