Abstract:
Objective To investigate the clinical effect of laparoscopic Dixon operation in patients with low rectal cancer. Methods The data of 68 patients with lower rectal cancer were retrospectively analyzed. The data were divided into 2 groups according to the treatment methods: the observation group of 34 cases with rectal anterior resection (Dixon) treatment and the control group of 34 patients underwent open surgery. The operation time, surgical bleeding amount, postoperative gastrointestinal function recovery time and hospitalization time of two groups were observed. The mortality rate and recurrence rate of two groups with 3 years follow-up were also counted. Results The operation time of patients in observation group was (135.8±21.4) min, which is shorter than that of control group (170.2±30.4) min (t=5.395). The amount of intraoperative bleeding in observation group was (51.6±30.2) mL, which is less than that in the control group (108.3±21.4) mL, (t=8.904). The gastrointestinal function recovery time of observation group was (28.8±1.4) h and the control group was (34.7 ±3) h (t=10.392). The hospitalization time of observation group was (8.5 ±1.3) d. It was shorter than that of control group (11.6 ± 2) d (t=7.578). There was statistically signi?cant difference between the two groups of data comparison (P<0.05). In 3 years follow-up, the mortality rate was 32.35% in the observation group and the recurrence rate was up to 8.82% in the observation group in the control group (χ2=0.569, χ2=0.159, P>0.05). There was no signi?cant difference between the two groups. Conclusion Laparoscopic conservative surgery for low rectal cancer can protect the anal sphincter, give small trauma to the body, make rapid recovery, improve the survival rate and reduce the recurrence rate, so it is worth popularizing.
