Full recovery after laparotomy takes at least a month or so, and may take longer if the recovery time is major surgery. Take laparoscopic appendicitis surgery as an example, the patient’s abdominal pain is most obvious on the day of surgery, and the abdominal pain will gradually decrease 3-5 days after the surgery, and the sutures are usually removed about a week after the surgery, at which time the patient will still feel a slight pain in the abdominal wound. Generally wait until about two weeks after the surgery before the abdominal pain can be gradually relieved, or even completely recede, so the full recovery is basically about 3 weeks after the surgery, when the patient’s abdominal pain is obviously reduced, and at the same time the diet will return to normal, and the stool will also return to normal. In case of major intra-abdominal surgery, such as radical surgery for gastric cancer or radical surgery for colon cancer, it may take a longer time, at least one month, or even two months for some patients, because the digestive tract needs to be removed and reconstructed, and after reconstruction, the patient has to restore the peristalsis of the gastrointestinal tract, normal diet and normal bowel movement.
