With the improvement of people’s living standard, lifestyle and dietary habits, the incidence of gastrointestinal tumors is increasing year by year. After the disease, many patients are afraid of open surgery. Laparoscopic technology makes everyone experience the benefits brought by minimally invasive technology, but many patients have many questions about laparoscopic minimally invasive technology. In terms of gastrointestinal tumor, what is the difference between laparoscopic minimally invasive surgery and normal open surgery? Compared with traditional surgery, laparoscopic surgery is like repairing underground pipeline. Laparoscopic surgery is performed by drilling a hole next to the road, entering the underground and using high-tech means to drill a hole underground and lay a pipeline, which has little impact on the traffic and buildings on the road; traditional open surgery is like digging up the whole road, laying a pipeline at a deep enough depth, and finally backfilling the road with soil and re-correcting the road surface. As you can imagine, traditional surgery is straightforward, intuitive, traumatic and has a long recovery time; laparoscopic surgery requires the use of specific tools, is highly technological, less traumatic and has a faster recovery. Overall, laparoscopic surgery has 5 major advantages: 1, multi-angle “inspection”, the effect of intuitive laparoscopy can be inspected from different angles and directions without involving the abdominal organs, and can even see some very deep location, to achieve the effect of intuitive inspection, reducing the misdiagnosis of leakage. 2.Fast recovery The lumpectomy is performed in the closed pelvic and abdominal cavity, which has little impact on the neighboring organs and causes little interference. The trauma suffered by the patient is far less than that of open surgery, and the patient recovers quickly after the operation, with few complications and sequelae. 3.Short hospitalization time The operation is operated by professional physicians, and the treatment can be completed in a short time without affecting normal physiological functions, and normal work and life can be resumed after the operation. 4.Good abdominal beauty effect Traditional surgery scars are in long lines, while lumpectomy does not leave scars or scars are greatly reduced, which is especially suitable for young women’s beauty needs. 5, reduce the burden of patients The surgery is minimally invasive, with less medication, low cost and fast recovery, reducing the burden of patients. It should be emphasized that any surgery has limitations. Laparoscopic surgery is not suitable if the following special conditions occur 1, severe heart, lung, liver and kidney insufficiency: laparoscopic surgery is not suitable. 2, huge pelvic and abdominal masses: the upper boundary of the mass exceeds the level of the umbilical port, the space available for surgical operation in the pelvic and abdominal cavity is limited, the mass obstructs the field of view, and the establishment of pneumoperitoneum or puncture may cause rupture of the mass. 3. Severe abdominal hernia or diaphragmatic hernia: the pressure of artificial pneumoperitoneum can press the abdominal contents into the hernia hole and cause impaction of abdominal hernia. The abdominal contents enter the thoracic cavity through diaphragmatic hernia, which may affect the cardiopulmonary function. 4, diffuse peritonitis with intestinal obstruction: because the intestinal segment is obviously dilated, the pneumoperitoneum needle or trocar needle puncture can easily cause the risk of intestinal perforation.
