Abstract: Objective To observe the clinical effect of laparoscopic-assisted Parks surgery on low rectal carcinoma.Methods Sixty-three patients with low rectal carcinoma treated from January 2013 to January 2017 were divided into two groups according to different therapies. The observation group (n=47) received laparoscopic-assisted Parks surgery, and the control group (n=47) received laparotomy. The incidence rate of postoperative complications, defecation function, operation time, bleeding volume, hospitalization time, and anal exsufflation time were recorded.Results The operation time, bleeding volume, anal exsufflation time, and hospitalization time of the observation group were significantly less than those of the control group (all Ps<0.05).The incidence rate of postoperative complications of the observation group (6.38%, 3 cases) was significantly lower than that of the control group (17.02%, 8 cases). The good recovery rate of defecation function of the observation group (55.32%, 26 cases) was significantly higher than that of the control group (31.91%, 15 cases), while the poor recovery rate of defecation function (8.51%, 4 cases) was significantly lower than that of the control group (21.28%, 10 cases).Conclusion Laparoscopic-assisted Parks surgery is better than laparotomy for the treatment of rectal carcinoma,deserving clinical promotion.
