Bowel adhesion is a dynamic pathophysiologic process and cumulative result. Therefore, “how long after surgery without intestinal adhesions” is not a scientific concept. Bowel adhesion after appendicitis surgery is due to inflammatory exudation and fibrin deposition caused by abdominal inflammation, with the gradual improvement of inflammation, it shows a gradual reduction process, generally in the postoperative period of 2 weeks no longer aggravate. After appendicitis surgery, abdominal inflammation will not immediately subside, usually need at least 1 week of anti-infection treatment to recover, in the process, inflammatory exudate, fibrin deposition will continue to exist, between the intestinal tube, the intestinal tube and the abdominal wall, there is the possibility of adhesion, the more serious the inflammation, the more serious the adhesion will be. Only when the inflammation subsides, the process of intestinal adhesions does not continue to progress. Usually, the loose adhesions are gradually absorbed 3-6 months after surgery. Most intestinal adhesions are asymptomatic, and occasional abdominal discomfort is difficult to diagnose. Only extensive or tight adhesions caused by severe abdominal inflammation have the potential to develop into intestinal obstruction.
