It is not difficult to do a reattachment surgery after rectal cancer surgery. The surgery is not particularly complicated overall, and only requires opening part of the abdominal cavity and reconnecting the originally traversed bowel back into the abdominal cavity. Under normal circumstances the surgery can be completed in about 2 hours and most of them are successful. However, due to the different physical conditions and recovery of each person, some people have poor health and slow recovery, even for benign tumors, they may fail after stoma and need another surgery. There are also some people who have a temporary stoma for malignant tumors, and there is still a possibility of recurrence and metastasis of the tumor after cure. After the stoma is returned, we should continue to do anti-tumor treatment, such as doing further adjuvant chemotherapy and radiotherapy to control the development of the disease. Rectal cancer patients should go to the hospital in time and under the guidance of doctors for treatment and postoperative recovery.
