Laparoscopic surgery is most recognized by patients as laparoscopic cholecystectomy. This is because it does not require an incision and the surgery is done by making only 3-4 holes in the abdomen. Therefore, it is popular among the Chinese people to say, “Can you do the surgery by punching holes?” . The “perforated” surgery referred to here is “laparoscopic surgery”, also known as “minimal incision surgery”. It marks a “quiet revolution” in traditional surgery and a trend toward minimally invasive DD surgery. Minimally invasive surgery represented by laparoscopic surgery is regarded as the development direction of surgery in the 21st century. Due to the magnifying effect of laparoscopy and the requirements of fine and accurate surgical anatomical access, it makes the surgical field clearer and is not easy to damage the surrounding tissues, and in the surgery of tumor patients, it achieves or even exceeds the range of tumor scavenging and resection requirements of open surgery, and the safety and thoroughness of the surgery are guaranteed. Compared with traditional open gastrointestinal surgery, laparoscopic surgery has the advantages of less trauma, less surgical blood loss, significant reduction of postoperative pain compared with open surgery, getting out of bed in the early postoperative period, mild systemic inflammatory reaction, less chance of infection, and faster recovery of postoperative body functions, etc., which are incomparable with open surgery. The Department of Gastrointestinal Surgery of our hospital is one of the first units to carry out laparoscopic gastrointestinal surgery in China. Hundreds of patients have undergone gastric and intestinal laparoscopic surgery, and all of them have achieved satisfactory results, and they deeply feel the benefits it brings to the patients. Which patients are suitable for laparoscopic gastrointestinal surgery? ①Colon, rectum benign disease patients: colonoscopy can not be removed colon, rectal polyps, need to do intestinal segmental resection of diverticulosis, sigmoid colon torsion, congenital megacolon, segmental colorectal muscle weakness, rectal prolapse, etc., are very good laparoscopic surgery indications. ② patients with malignant diseases of colon and rectum: radical and palliative surgery for colon and rectal cancer, lumpectomy or colostomy, etc. are good indications for laparoscopic surgery. ③ Intestinal adhesion release, appendectomy, diagnostic abdominal exploration, ④ gastric fundus folding, gastric reduction surgery for obese patients, gastrointestinal mesenchymal tumors, early gastric cancer and other surgeries. Who is not suitable for laparoscopic gastrointestinal surgery? Serious disorders of heart, lung, liver and kidney functions, obvious bleeding tendency, serious intra-abdominal adhesion, accompanied by serious diseases of other organs of the whole body, etc. Tumors too large to infiltrate the uterus, bladder, ureter, small intestine, duodenum and pelvis and other adjacent organs are contraindicated. Shortcomings of laparoscopic surgery: Since laparoscopic surgery is different from traditional open surgery, it is difficult to operate, requires a high level of technology, the doctor receives a long time of training, has a high degree of dependence on instruments and equipment, and some of the instruments have not yet entered the scope of reimbursement by medical insurance, and the cost of the operation is higher than that of open surgery.
