摘要Abdominal cocoon (AC) is a rare condition,that leading to acute or chronic small bowel obstruction,characterized by a total or partial encapsulation of the small bowel by a fibrous membrane or sac-like cocoon,sometimes colon,uterus or accessories are encased in.The disease is characterized as either primary or secondary to other causes.The main reported clinical manifestations of AC are acute/subacute complete/partial intestinal obstruction and abdominal mass.[1] Here,we report a rare case of AC presenting as umbilical hernia,and to our knowledge,it is only a few cases of this entity have been reported previously.Even though preoperative diagnosis of AC is difficult and normally laparotomy is the main solution,in our case,we chose the method which combines laparoscopy with open surgery,it solved patient problem quickly and efficiently,and that further confirmed laparoscopic surgery has great significance in diagnosis and treatment of AC.
