Dr. Yin Lu, Professor of Surgery at Ruijin Hospital and President of the International Colorectal Cancer Association China Chapter, was the first to carry out laparoscopic surgery for inflammatory bowel disease, especially Crohn’s disease, in China. He has successfully applied the mature laparoscopic minimally invasive technology to the treatment of inflammatory bowel disease, bringing gospel to the majority of patients with inflammatory bowel disease, especially Crohn’s disease. With profound academic attainments in gastrointestinal surgery and nearly 20 years of clinical experience in surgery, he has made bold improvements and innovations to the original surgical approach and taken the lead in laparoscopic surgery for inflammatory bowel disease, especially Crohn’s disease, in China. Through continuous surgical practice, his surgical team 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 incision length of 20cm to 30cm, not only damage, and the healing scar is located in the middle of the abdomen obvious image aesthetics, especially for young patients more difficult to accept. Professor Yin Lu of Ruijin Hospital, through laparoscopic surgery, has reduced the length of the obvious scar of the surgical wound to about 1/3 of that of traditional caesarean surgery, about 8cm horizontal incision in the lower abdomen, which not only causes less damage, but also is 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.
