At present, laparoscopic minimally invasive surgery is mostly adopted to perform resection of the right hemicolectomy. The specific steps are as follows: a. The patient is placed in a herringbone position after general anesthesia, and the surgical area is routinely disinfected and sterile cavity towels are laid. Second, five puncture holes were implanted through the abdominal wall, laparoscopic instruments were placed through the puncture holes, a pneumoperitoneum was established, and the entire abdominal cavity was explored for adhesions. Third, along the submesenteric artery, the ileocolic artery was freed and ligated at the root. At the same time, the superior mesenteric artery was continued upward to protect the duodenum from injury and reached the posterior colonic space. Fourth, free the right gastrocolic ligament to reach the colonic hepatic flexure. Fifth, the adhesions between the colon and the right abdominal wall were freed upward in the ileocecal region, and the ileum 20 cm from the ileocecal region was freed. Transverse ileum and end-to-end colonic anastomosis were performed, the right hemicolectomy was performed, the surgical wound was completely hemostatic, and an abdominal drainage tube was placed, and the operation was completed.
