The bad effects of appendectomy include the following: 1. Patients who are in a primary care hospital, or who are operated on by junior doctors with poor hemostasis disposition, may result in postoperative bleeding phenomena. If the appendiceal stump is not handled well, it may lead to intestinal fistula, which is a more serious complication.2. Intestinal adhesions may occur in any laparotomy, and if the appendix is septic, the adhesions will be relatively serious and may further develop into intestinal obstruction.3. Due to septic and perforated appendix during surgery, pus that contaminates the surgical incision can very easily lead to incisional infection, and some obese patients It is also easy to develop fat liquefaction infection. The above are some of the hazards after appendectomy, which are usually caused by improper disposal during or after the operation. Since the appendix itself does not have too much efficacy, it will not have a direct impact on the body after removal.
