Abstract：The patient was a middle-aged woman with cancer of the hepatic flexure of the colon(cT 3-4 NxM 0).Total laparoscopic radical extended right hemicolectomy(D 3+CME)was performed via caudal-dorsal approach.First,the posterior space of the ascending colon and the anterior pancreaticoduodenal space behind the transverse colon were dissected.Then,the left edge of the superior mesenteric artery was used as the boundary of mesocolon of right half colon,and the relevant arteries and veins were ligated,and the lymphatic tissue was dissected from the roots.Finally,No.206 lymph nodes were freed and dissected from the gastroepiploic arch.The transverse colon and ileum was performed followed by side-to-side anastomosis(Overlap).Total laparoscopic extended right hemicolectomy(D3+CME)can completely remove the mesentery within the tumor bearing area under the guidance of membrane anatomy,reduce intraoperative bleeding,and especially completely remove the cancer metastasis between the fat in the mesentery,that is,"the fifth metastasis".
