Effect of laparoscopic complete mesocolic excision of colon cancer on short-term and long-term prognosis of patients

Abstract

Objective To investigate the effect of laparoscopic complete mesocolic excision of colon cancer on short-term and long-term prognosis of patients. Methods The clinical data of 80 patients with colon cancer admitted to our hospital from April 2008 to April 2013 were retrospectively collected. The patients were divided into laparoscopic group and open group according to different surgical methods, each 40 cases. They were given laparoscopic complete mesocolic radical resection and traditional laparotomy respectively. Data analysis was performed by statistical software SPSS21.0. The short-term efficacy index of the two groups was compared by two independent samples t test. The complication rate and long-term prognosis of the two groups were compared by χ2 test. Results The intraoperative blood loss and anal exhaust time of the laparoscopic group were shorter than those of the open group (P 0.05); The total incidence of postoperative complications in the laparoscopic group was 5.0%, which was lower than 22.5% in the open group, but the difference was not statistically significant (χ2 =3.5294, P>0.05). The 3-year recurrence rate was 10.0% in the laparoscopic group, which was significantly lower than 30.0% in the open group. The difference was statistically significant χ2 =5.0000, P<0.05). The 3-year survival rate in the laparoscopic group was 95.0%, which was significantly higher than 80.0% in the open group. The difference was statistically significant (χ2 =6.2745, P<0.05). Conclusion Laparoscopic complete mesocolic excision for the treatment of colon cancer can significantly reduce intraoperative blood loss, shorten anal exhaust time, which lymph node dissection was complete, complication rate is lower, and short-term and long-term prognosis are all better, the effect is significant and it is worthy of promotion and application.
