The operation went smoothly, and the patient was discharged from bed one day after the operation and discharged from the hospital one week after the removal of the presacral tube. Zhang Bin, Department of General Surgery, Henan Cancer Hospital The advantages of this operation: 1. Laparoscopic operation, no incision in the abdominal wall, reduces the trauma of the patient, reduces the postoperative pain, especially reduces the occurrence of postoperative intestinal adhesions. Compared with conventional open surgery, the patient has only 5 poke holes in the abdominal wall. 2. The colostomy is led out of the body through the peritoneum, which reduces the occurrence of parastomal hernia and improves the long-term quality of life of the patient after surgery compared with conventional stoma. At present, we routinely use laparoscopy to treat colorectal cancer and have achieved better near and long-term results. Laparoscopic technology is now widely carried out with mature technology, which can bring less pain to patients. The consequences of surgeons not mastering the advanced technology are serious.
