In recent years, the mature laparoscopic minimally invasive technology has been successfully applied to the treatment of inflammatory bowel disease, bringing good news to the majority of patients with inflammatory bowel disease, especially Crohn’s disease, and through continuous surgical practice, it is found that laparoscopic treatment of inflammatory bowel disease, including Crohn’s disease, has many advantages compared with traditional open surgery: 1, minimally invasive wound is small: traditional inflammatory bowel disease dissection surgical incision length 20cm to 30cm, The scar is located in the middle of the abdomen after healing, which is more difficult to accept especially for young patients. Through laparoscopic surgery, Xue Qi’s medical team at Southern Hospital has reduced the length of the obvious scar of the surgical wound to about 1/3 of that of the traditional caesarean operation, which is about 8cm horizontal incision in the lower abdomen, which is not only less damaging but also more beautiful. 2, less bleeding: because the laparoscope is working under a magnified field of view, it makes the tissue anatomy such as blood vessels clearer and the operation more delicate, with less tissue damage and less bleeding; secondly, the pneumoperitoneum pressure of the laparoscope itself can counteract the vascular pressure thus reducing bleeding. 3, almost completely in the abdominal cavity to complete the operation: except for the removal of the intestinal tube need to drag part of the intestinal segment out of the abdominal cavity, other surgical operations are basically completed in the abdominal cavity, reducing the contact between the intestinal tube and the external environment, so that the intestine is basically in the physiological environment, which is conducive to reducing external pollution and protecting intestinal function, early recovery of intestinal peristalsis after surgery, early feeding. 4, fast recovery, less complications: due to laparoscopic magnification, the surgical anatomy is more delicate, less tissue damage, less bleeding, the intestinal surgery process is almost completed in the abdominal cavity, the postoperative patient’s physical state is better than the traditional caesarean operation, the intestinal function recovers faster, infection, bleeding, postoperative abdominal adhesions intestinal obstruction and other complications are less, and the hospitalization time is shorter.
