Abstract:

Under general anesthesia, 5 holes were adopted for laparoscopic puncture. Following the principle of from far to near, the abdominal cavity was explored comprehensively. The medial-to-lateral approach was used to deal with vessels. Marked by superior mesenteric vein, the roots of ileocolic artery and vein, right colonic artery and vein and middle colonic artery and vein were isolated, ligated and cut off below the horizontal segment of the duodenum. Meanwhile, the lymph nodes of 203 groups, 213 groups and 223 groups were removed. Extended the posterior space of the right colon toward the cephalic and lateral side, and dissected the hepatic flexure of colon and the lateral ascending colon. 5cmincision in the middle of upper abdomen was made to remove ileocecal part, ascending colon, hepatic flexure of colon, transverse colon and part of greater omentum. The ileum was cut off 10cm away from the ileocecal part, and the colon was cut off 10cm away from the tumor. End-to-side ileocolic anastomosis was performed with a tubular stapler.
