Pericardial cysts are cysts that occur near the pericardium, most commonly at the right diaphragmatic angle, but also at higher locations, even extending to the upper mediastinum. Surgical treatment is the more effective measure for this disease and the results are more satisfactory, but some complications occur, mainly some postoperative complications, such as incisional infection, postoperative intestinal adhesions and pneumonia. It should be especially noted that postoperative intestinal adhesions are a common complication after laparotomy, but intestinal adhesions can also occur in pericardial cysts when some cysts are located low and the surgery involves the abdominal cavity. Clinical abdominal pain and abdominal distension are the main symptoms, and the incidence is high, and adhesive intestinal obstruction can occur in severe cases.
