Abstract: Objective To evaluate the safety and therapeutic effects of applied in a three plane fashion laparoscopi -assisted resection of the right colon for right colon cancer.
Methods Form 2014.11 to 2018.6,44 patients were randomly divided into two groups,20 patients in the study group were treated with three plane radical operation for right colon cancer.Applied in a three plane fashion to laparoscopy-assisted resection of  the right colon was performed on 20 patients with right colon cancer.The upper colon was the first plane.The outside of duodenum is the second plane.The anterior pancreaticoduodenal space is the third plane.In the control group,24 cases were treated by traditional middle approach.The section of the right colon and end to end anastomosis of the residual bowels were performed through a small incision in the abdomen.The intraoperative and postoperative conditions, the number of dissected lymph nodes and complications were compared between the two groups.
Results Most patients completed laparoscopic operation except one case.In the study group,the operation time of laparoscopy was (66.8±6.5)minutes and the intraoperative blood loss was (25.3±2.5)ml.In the Control group,laparoscopic operation time was (90.4±15.8)minutes,intraoperative blood loss was (40.2±6.9)ml.The operation time and blood loss of the study group were better than those of the control group（P＜0.05）.There was no significant difference between the two groups in the number of lymph nodes,the average length of auxiliary incision,the average length of postoperative hospital stay,incision infection,puncture complications,intestinal fistula and abdominal infection（P＞0.05）.
Conclusion Three plane operation which is to divide into three planes was applied for resection of the right colon cancer.Thus,the difficulty of operation is reduced,at same time,which is more accessible to young surgeon.
