A Comparative Study On Pelvic Nerve Guided Laparoscopic Radical Resection For Rectal Cancer

Objective: to explore the prospective randomized controlled study of pelvic nerve guided and non-pelvic nerve guided laparoscopic radical resection of rectal cancer surgery’s curative effect, to study the protective effect of the former with rectal cancer genitourinary function.Methods: we selected 70 cases who meet the inclusion criteria from our hospital from February 2013 to February 2015,then randomly divided them into two groups, and each group had 35 cases, the observation group(P group) underwent pelvic nerve guided laparoscopic radical resection of rectal carcinoma and the control group underwent non-pelvic nerve guided of laparoscopic resection of rectal cancer. Compare and analyze the operation time, intraoperative blood loss, the number of lymph node dissection, the distance from the lower margin of the tumor to surgical margin, the incidence of the cancer cell of surgical margin and the incidence of postoperative complications between the two groups. According to the evaluation standard, the two groups of patients were followed up the function of urination 2 weeks、6 months and 12 months after operation, the function of erection and ejaculation 6 months and 12 months after operation.Results: the average operation time of P group was slightly longer than that of N group, and the difference was statistically significant(P<0.05). There were no significant differences in blood loss, lymph node dissection, distance between the lower margin of the tumor to surgical margin, cancer cell disease detection, and postoperative complications between the two groups(P>0.05). 2 weeks after operation, the voiding dysfunction rate of P group patients was 20.00%, N group was 42.86%.6 months after operation, the voiding dysfunction occurrence rate of P group was 5.71% and ejaculatory dysfunction occurrence rate was 25.71%, erectile dysfunction was 45.71% and the corresponding rate of N group was respectively 25.71%, 51.43%, 71.43%, the difference was statistically significant(P < 0.05). 12 months after operation, the micturition function of all patients reached the level I, the two groups had no statistical difference(P > 0.05), the incidence rate of ejaculatory dysfunction in P group fell to 20.00%, the erectile dysfunction rate fell to 37.14%, the corresponding rate of N group was respectively 42.86% and 62.86%, the difference has statistical significance(P < 0.05).Conclusion: pelvic nerve guided rectal cancer radical resection can effectively protect the pelvic autonomic nerve of male patients with rectal cancer, and it has significant advantages in reducing the incidence of postoperative urinary dysfunction and sexual dysfunction.
