Non-surgical treatment: mainly indicated for appendiceal abscess, appendicitis in early and late pregnancy and appendicitis in advanced age combined with major organ lesions. 1.Basic treatment: bed rest, diet control, appropriate rehydration and symptomatic treatment. 2, antibacterial treatment: broad-spectrum antibiotics (such as ampicillin) and anti-anaerobic drugs (such as methotrexate) can be used for intravenous infusion. 3, acupuncture treatment: foot three li, appendix points can be taken, strong stimulation, stay for 30 minutes, twice a day for three days. 4.Chinese medicine treatment: external application is suitable for appendiceal abscess, and “Sihuang San” can be used; internal use is mainly to clear heat and detoxify, move Qi and blood, and pass through the lane to attack, and “Dahuang Mudanpi Tang” can be used with reduction. Surgical treatment: 1. Surgical principles: After the diagnosis of acute appendicitis is clear, early surgical treatment should be performed, which is safe and can prevent the occurrence of complications. Early surgery means that the appendix is still in the lumen obstruction or only congested edema when the surgery cut down, at this time the operation is simple. If the operation is performed after suppuration or gangrene, the operation will be difficult and the postoperative complications will increase significantly. 2.Surgical choice: The surgical methods for different clinical types of acute appendicitis are also different. (1) Acute simple appendicitis, appendectomy, incision stage one suture. In recent years, trans-laparoscopic appendectomy has been performed for this type, but skilled technique is required. (2) Acute purulent or gangrenous appendicitis, appendectomy is performed; if there is pus in the abdominal cavity, the peritoneum can be closed after removing the pus and the incision is placed with latex sheet for drainage. (3) In case of periappendiceal abscess, if there is no tendency of restriction, perform incision and drainage, and depending on the specific situation during surgery, decide whether the appendix can be removed; if the appendix has been detached, try to remove it and close the cecum wall to prevent intestinal fistula. If the abscess is confined to the right lower abdomen and the condition is stable, do not force appendectomy, give antibiotics and strengthen systemic support therapy to promote pus absorption and abscess remission. What are the complications of untimely treatment of appendicitis? Abdominal abscess: abscess around the appendix. Common sites are the pelvis, subdiaphragm and intestinal space. Clinical manifestations include abdominal distention with paralytic intestinal obstruction, signs of peritoneal irritation, painful pressure masses and systemic symptoms of infectious toxicity. Internal and external fistula: If the periappendiceal abscess is not drained in time, in some cases the abscess may penetrate into the small or large intestine, or into the bladder, vagina or abdominal wall, forming various internal or external fistulas. Portal phlebitis: Infected thrombus in the appendiceal vein, along the superior mesenteric vein to the portal vein, causing inflammation of the portal vein. There is clinical enlargement and pressure of the liver, jaundice, chills, and high fever. It may develop into bacterial liver abscess and infectious shock. Septic appendicitis is prone to incisional infection and intestinal adhesions after surgery, lifelong recurrent abdominal pain, and incapacitation.
