The clinical cost of minimally invasive surgery varies according to the type of disease of the patient. If the inflammation of the appendix is mild and the patient has acute simple appendicitis, the operation is relatively simple and the patient recovers quickly after the operation, and the total cost is usually about 11,000 RMB. If the inflammation of the appendix is more severe, with local perforation and more pus accumulation in the abdominal cavity. At this time, the patient’s bowel venting and defecation functions recover slowly after surgery, and the hospitalization time is longer, and the cost is about 13,000 yuan. If the patient undergoes minimally invasive surgery for acute gangrenous cholecystitis, the patient’s condition will recover slowly after surgery because of the heavy inflammation of the gallbladder and more inflammatory exudate in the abdominal cavity, and the total cost of treatment will be about 20,000 yuan. Third, patients with gastric malignant tumor undergo laparoscopic radical treatment of gastric cancer and lymph node dissection, and the total treatment cost for patients after surgery is about RMB 50,000-60,000.
