Abstract:

Objective To study the effect and safety of laparoscopic middle approach and caudal medial approach in the operation of right colon cancer. Method 85 patients with right colon cancer in Yulin Third People's Hospital from April 2022 to April 2024 were selected. All patients received radical resection of right colon cancer. They were divided into control group and observation group according to different approaches. The control group (n=42) was treated with intermediate approach surgery, and the observation group (n=43) was treated with oneway loop surgery via caudal medial approach. The perioperative indicators, tumor markers, stress indicators and complications of the two groups were compared. Result The number of lymph node dissection in the observation group was more than that in the control group, and the operation time was shorter than that in the control group, and

the intraoperative blood loss was less than that in the control group, the differences were significant (P ＜ 0.05). After operation, the carcinoembryonic antigen, carbohydrate antigen 125, carbohydrate antigen 19-9, cortisol, adrenocorticotropic hormone, norepinephrine in the observation group were signifi cantly lower than those in the control group (P ＜ 0.05). The conversion rate of laparotomy (0 vs 9.52%) and the total complication rate (6.98% vs 23.81%) in the observation group were lower than those in the control group, and the differences were significant (P ＜ 0.05). Conclusion The medial caudal approach of one-way loop laparoscopic surgery for right colon cancer needs shorter time, less intraoperative blood loss, which is more conducive to the postoperative recovery of patients, and the operation idea is clear, which can avoid repeated overturning of the mesentery and intestines, and is more conducive to the completion of lymph node dissection.
