目的 探讨直肠癌术后性功能障碍发生的主要原因及其预防措施。方法 经对盆腔神经丛解剖和生理知识的复习和研究，将本院近年来行直肠癌根治术后男性患者６２ 例分为两组。一组为保留盆腔神经丛３０ 例，另组为传统手术组３２ 例。将术后性功能障碍发生率进行配对分析和χ２ 检验，Ｐ＜ ０．０１ ，两组比较差异有非常显著性。结果 直肠癌根治术中若注意保留盆腔神经丛，术后性功能障碍的发生率将明显减少。结论 保留盆腔神经丛能有效地预防直肠癌术后性功能障碍的发生。
Objective To investigate the causes of sexual dysfunction after rectal cancer and its preventive measures. Methods After reviewing and studying the anatomy and physiology of pelvic nerve plexus, 62 cases of male patients undergoing radical rectal cancer surgery in our hospital were divided into two groups. One group had 30 cases of pelvic plexus preservation and the other group had 32 cases of traditional operation group. The incidence of sexual dysfunction after paired analysis and χ2 test, P < 0.01, the difference between the two groups was very significant. Results If the pelvic plexus was preserved during radical resection of rectal cancer, the incidence of postoperative sexual dysfunction would be significantly reduced. Conclusion Preservation of pelvic plexus can effectively prevent the occurrence of sexual dysfunction after rectal cancer.
