Rectal cancer will hurt for about 2-3 days after surgery, but different patients have different pain tolerance and feel differently. Most rectal cancers are now treated with minimally invasive surgical methods, that is, laparoscopic radical rectal cancer or laparoscopic-assisted radical rectal cancer, and for many patients the abdominal wounds are relatively small, usually with 4 or 5 puncture holes. If a prophylactic stoma is required there may be a wound or stoma in the abdomen, if there is no stoma and there are 4 or 5 puncture holes in the abdomen, the pain is very mild and the patient is pain free 1-2 days after the procedure. If the patient undergoes transabdominal perineal radical surgery for rectal cancer, there is a wound in the perineum and the wound is relatively large, it is possible that the pain will be on the high side, and most of the patients do not feel any pain with oral analgesics or prophylactic analgesics.
