Minimally invasive laparoscopic techniques have been introduced to China since 1991 and have not only gained rapid popularity but are also widely used in all types of general surgery because of their advantages of less trauma, less pain, faster recovery and cosmetic appearance. In layman’s terms, almost all general surgical procedures can be performed with laparoscopic techniques. However, some people say that laparoscopic appendectomy is a “cannon shot”. It is true that the cost of laparoscopic appendectomy is higher than that of traditional open appendectomy, but they fail to see that the actual benefits of laparoscopic appendectomy to patients cannot be measured in money. As we all know, the main method of treatment for acute appendicitis is appendectomy. At present, many people still have a deep misunderstanding about laparoscopic appendectomy, believing that open appendectomy can be completed with a small incision of less than 3 cm, so laparoscopy is not superfluous? In fact, this small incision appendectomy is only a very small part of appendectomy compared to some simple and easy to find appendix. There are many unavoidable complications of open appendicitis surgery, such as the high incidence of postoperative intestinal adhesions and intestinal obstruction due to the direct contact of the surgeon’s hand with the intestinal canal or the repeated irritation of the intestinal wall plasma membrane during surgery in order to clear the pus. Open surgery to remove the diseased appendix directly from the incision is prone to incisional infection (up to 7%-30%). In acute appendicitis, pus and exudate accumulate in the intestinal space and pelvic cavity, and open surgery is not easy to clean up thoroughly due to the limitation of the incision, resulting in residual abscess or pelvic infection, which may cause secondary infertility in female patients. In the case of retroperitoneal or subhepatic appendix, open surgery must enlarge the incision or even open the incision to a large size, often with a longer blind search. In the management of exceptionally obese patients, open surgery can hardly be completed with a small incision, and even with an enlarged incision, the higher rate of incisional infection is not easily controlled. Some acute abdominal conditions are easily misdiagnosed as appendicitis, such as gastric perforation, pelvic inflammatory disease, pediatric intestinal diverticulum, and intussusception, and surgical appendectomy for these diseases cannot be done …… Laparoscopic appendectomy is performed by making 2 or 3 small 0.3 to 0.5 cm incisions in the abdomen along the skin line, one at the umbilicus, and placing from these small incisions with All the organs and operations in the abdominal cavity are shown through the monitor, so the surgeon can easily find the diseased appendix (no matter where it grows or how fat the patient is), and then remove the appendix with a special ligature and use the flushing system to flush out the abdominal cavity, as well as to find out in time whether all the other organs in the abdominal cavity are lesions occur. Therefore, even if other acute abdominal conditions are misdiagnosed as appendicitis, the operation can be completed laparoscopically, so that any difficulties of open surgery can be solved laparoscopically. Laparoscopic appendicitis surgery has the following advantages: 1, laparoscopic surgery does not directly touch the diseased appendix by hand, the chance of residual abscess and intestinal adhesion and intestinal obstruction is almost zero, while the incision of laparoscopic surgery is small, no fluid, no suture, the appendix is removed without touching the incision, and incision infection rarely occurs. 2, laparoscopic surgery has little interference with the abdominal cavity, light pain, early postoperative activity of patients, fast recovery of gastrointestinal function, and very little incisional infection, so it shortens the hospital stay more often. 3, laparoscopic surgery has only a few small holes, almost no scar after surgery, and does not change the appearance of the abdomen. It is especially suitable for female, pediatric, obese patients and all patients who have difficulties in open surgery. Therefore, laparoscopic appendectomy instead of open appendectomy is bound to become the current development trend.
