The common sequelae of patients after appendicitis surgery are mainly the following: I. Adhesive intestinal obstruction, mostly seen in appendix with septic or gangrene-like changes, resulting in a large amount of inflammatory exudate in the abdominal cavity, although surgical removal of the appendix can still cause significant intestinal adhesions, after surgery patients can appear abdominal pain, abdominal distension, anal stop exhaustion, defecation and other manifestations of intestinal obstruction. Second, abdominal bleeding, the ligation of the appendiceal artery is not complete when appendectomy is performed, and postoperative oozing of blood from the appendiceal artery may occur. If the amount of bleeding is large, it may cause hemorrhagic shock and endanger the patient’s life. Third, intestinal fistula, if the root of the patient’s appendix is brittle in texture and the appendix root is not purse-string sutured intraoperatively. After surgery, fecal matter in the colon may leak into the peritoneal cavity through the appendiceal root, causing acute diffuse peritonitis in the abdominal cavity, which requires a second surgical procedure. It is only by enhancing drainage that the patient’s abdominal infection symptoms can be controlled more quickly and better treatment results can be achieved.
