RESUMO
Objective To explore the value of complete mesocolic excision ( CME) for patients with colon carcinoma. Methods The 68 patients with colon carcinoma were divided into CME group (n=34) and control group (n=34) randomly. The patients in CME group were managed CME and the control group were arranged traditional open operation. The operation condition, preoperative complications, a-mount of lymph node scavenged,and the relapse rate of the 2 groups were contrasted. Results The operation period,the hospital stays,period of passage of gas by anus,the drainage volume post 3 days of operation and the period of drainage tube extraction of CME group were respec-tively(158 ± 38) min,(13. 4 ± 4. 0),(2. 3 ± 0. 5) d,(123. 3 ± 20. 5) mL,(12. 3 ± 2. 5) d,with no difference compared to control group (P>0. 05). The intraoperative bleeding volume of CME group (112. 3 ± 35. 5) mL was less than that of control group (146. 6 ± 36. 7) mL (P0. 05). But the amount of lymph nodes scavenged of patients in TNM Ⅱ and Ⅲ of CME group (18. 6 ± 6. 7),(22. 6 ± 8. 6) was more than that of control group (15. 2 ± 4. 8),(16. 8 ± 6. 7)(P=0. 019 0,0. 002 8). The relapse rate in CME group (0. 0%) was lower than that in control group (17. 6%)(χ2 =4. 569 9,P=0. 032 5). Conclusion CME will not increase the risks of radical operation for colon carcinoma,but can scavenge more lymph nodes and decrease the tumor relapse rate.
