经腹直肠癌切除术中保留盆腔自主神经对男性性功能影响的临床研究

目的：探讨经腹直肠癌切除术（Dixon术）中保留盆腔自主神经对男性性功能影响的临床价值，为临床诊断治疗提供参考。方法：将本组96例行Dixon术的直肠癌男性患者，根据是否保留盆腔自主神经分为对照组（n＝48）和观察组（n＝48）；对照组行Dixon术后未保留盆腔自主神经；观察组行Dixon术后保留盆腔自主神经。结果：观察组术后勃起功能障碍率（29.17％）显著低于对照组（68.75％），且有显著性差异（P＜0.05）；观察组术后射精功能障碍率（22.92％）显著低于对照组（70.83％），且有显著性差异（P＜0.05）；观察组术后排尿功能障碍率（18.75％）显著低于对照组（70.83％），且有显著性差异（P＜0.05）；两组术后1年后随访肿瘤复发率比较无显著性差异（P＞0.05）。结论：直肠癌Dixon术中对盆腔自主神经保留可保护男性性功能，且不会增加其肿瘤局部复发率。

Effect of colorectal cancer surgery Dixon reserved pelvic autonomic nerve on male sexual function

Objectives：To explore the effect of colorectal cancer surgery Dixon reserved pelvic autonomic nerve on male sexual function,to provide reference for clinical diagnosis and treatment.Methods：96 colorectal cancer patients received 96 Dixon routine surgery,depending on whether reserved pelvic autonomic nerve,were di-vided into control group （n=48）and observation group （n=48）;control group did not reserve pelvic autonomic nerve after the operation,while observation group underwent postoperative pelvic autonomic nerve preservation. Results：The rate of postoperative erectile dysfunction （29.17%）was significantly lower in observation group than that of the control group （68.75%）,with significant difference （P〈0.05）;the postoperative ejaculatory dysfunction rate （22.92%）in observation group was significantly lower than in the control group （70.83%）,with significant difference （P〈0.05）;the voiding dysfunction rate of observation group （18.75%）was significantly lower than that of the control 〈br〉 group （70.83%）,with significant difference （P〈0.05）;postoperative follow-up showed no significant difference in tumor recurrence rate 1 year after （P〉0.05）.Conclusion：Colorectal cancer surgery Dixon with pelvic autonomic nerve preservation can protect males’sexual function,while not increase its local cancer recurrence rate.
