Whether or not to put an abdominal drain in a patient who has had surgery for appendicitis depends on the general state of the patient. If the patient’s appendicitis is mild and the operation goes well, and there is no obvious pus or foci of infection in the abdominal cavity, it is usually not necessary to put a laparoscopic drain. If the patient’s appendicitis is more severe and there is more abscess in the abdominal cavity, and there are still inflammatory lesions despite irrigation, a laparoscopic drain can be placed and the patient’s condition can be observed. If the patient’s abdominal tube is draining more and clearer, it can be removed early. If the patient has purulent fluid in the abdominal drainage tube and the amount is relatively high, this indicates that the patient may have an abdominal infection in the abdominal cavity. Placing an abdominal drain allows observation of the patient’s condition and the next step of treatment. Therefore, the decision to place or not to place an abdominal drain depends on the patient’s condition.
