对25例男性直肠癌切除后性功能进行调查。平均年龄为42．5岁，Miles手术18例，性欲减退8例（44．4％），勃起障碍11例（61.1％），射精障碍13例（72．2％）。Dixon手术7例，性欲减退1例（14.3％），勃起障碍1例（14.3％），射精障碍2例（28．6％）。认为手术损伤盆腔神经是造成术后病人性功能障碍的直接和主要因素。防治关键在于术中完整地保护植物神经，注意剥离层次和切除范围。
Sexual function was examined in 25 men with rectal cancer after resection. The average age was 42.5 years, Miles was performed in 18 cases, libido was reduced in 8 cases (44.4%), erectile dysfunction in 11 cases (61.1%), and ejaculatory dysfunction in 13 cases (72.2%). Dixon surgery in 7 cases, 1 case of loss of libido (14.3%), 1 case of erectile dysfunction (14.3%), ejaculation disorders in 2 cases (28.6%). It is believed that the surgical injury to the pelvic nerve is a direct and major factor leading to postoperative sexual dysfunction. The key to prevention and control is to completely protect the autonomic nerve during surgery, and pay attention to the level of delamination and the scope of resection.
