At present, the application of laparoscopic technology in gastrointestinal surgery has made a rapid development, and the advantages of laparoscopic minimally invasive surgery for acute appendicitis, gastrointestinal perforation and colorectal cancer are recognized by more and more surgeons, and its application shows a broad prospect. Compared with traditional open surgery, laparoscopic gastrointestinal surgery has some advantages that cannot be compared with traditional surgery. 1, small tissue trauma traditional open surgery due to the long operation time, large surgical incision, the continuous pulling of the incision spreader easily causes damage to the soft tissues around the incision, making the patient’s wound pain more obvious after traditional open surgery and long postoperative recovery time. The lumpectomy is a minimally invasive surgery that requires only a few small 0.5-1.0 cm holes in the abdominal wall to put in the corresponding instruments for surgery, and there is no or only a few centimeters long small incision (for removing the surgical resection specimen) after the surgery, so the patient’s postoperative pain is not obvious and can get out of bed early, with fewer wound complications and faster recovery. 2. The TV image system of lumpectomy can magnify the field of view of the operation 4-6 times, so that the whole operation process is completed with ultrasonic knife under direct vision with fine and bloodless dissection, which is more delicate and thorough, and can ensure that the clearance and resection range of lumpectomy is more thorough than that of traditional open surgery. 3. The hands of surgeons frequently touch the tissues, which may cause tumor metastasis; while the hands of surgeons in lumpectomy are outside the operation field, which reduces the metastasis of tumor; the lumpectomy field is clearer due to the magnification of the lumpectomy, and the main technique is sharp dissection, which first disconnects the blood vessels and blocks the metastatic channels of tumor; the operation under high-definition field, the lymphatic clearance is complete during the operation, which eradicates the harboring tumor cells. 4. Minimally invasive lumpectomy is performed under the closed state of abdominal cavity, so that the physician’s hands do not enter the patient’s abdominal cavity, which causes less disturbance to the organs and less bleeding, and the gastrointestinal tract recovers quickly after surgery. Complications such as intestinal adhesions rarely occur.
