The national requirement for laparoscopic rectal cancer surgery is to keep the hospital stay as short as possible, generally the average hospital stay is about 8, 9, or 10 days. However, if there are a lot of problems, such as outpatients who are found to have rectal problems, they have to undergo examinations, i.e. biopsy, and after the biopsy, they have to do CT, MRI, ultrasound, chest X-ray, and auxiliary laboratory examinations, and there are many examinations to prepare for the grading or staging of the patient’s disease before surgery. There are many tests to prepare the patient for the grading or staging of the disease before surgery. If the surgery goes well and the recovery after the surgery is relatively smooth, the time spent in the hospital after the surgery is about 9-10 days, but there are still problems with the recovery after the surgery, such as bleeding, infection, poor wound healing, obstruction, or other complications in elderly patients, such as lung infection, blood clots in the lower extremities, or even heart problems. or even heart problems are possible. Therefore, the timing of discharge or length of stay is determined on a patient-by-patient basis.
