Abstract: Abdominal cocoon is a rare, peritoneal disease with a disorder of the autoimmune system. It is a disease of acute and chronic intestinal obstruction caused by a thickened peritoneum that wraps or partially wraps the small intestine. The cause and mechanism of its etiology are not yet fully understood which need further study. The clinical features of the abdominal cocoon symptoms are lack of specificity, which can easily lead to misdiagnosis and missed diagnosis. There is no perfect treatment standard for treatment. With the promotion and popularization of CT, laparoscopic and other technologies, the diagnosis and treatment of abdominal cocoon symptoms can be improved. Although conservative treatment can delay the progression of abdominal cocoon symptoms, it still cannot solve the problem fundamentally. Surgical treatment is still the best choice for patients with abdominal cocoon.
