The main reason for the large stomach after laparoscopy is the state of intestinal paralysis, the abdomen is in a state of relaxation, and the stomach appears to be larger. In addition, there may be residual gas in the abdominal cavity from anesthesia, which may also cause an increase in the abdominal contents, resulting in an enlarged abdominal cavity. Both of these factors can return to normal after the anesthesia has passed and the anesthesia time has been recovered, so it is not worth questioning whether laparoscopic surgery is particularly harmful to the thoracic cavity or the abdominal cavity. Clinical laparoscopic surgery is carried out more and more, the patient can get more and more benefits, the operation time is short, less traumatic, and most importantly, the abdominal cosmetic incision, which is a great benefit to many patients.
