摘 要:目的探讨动脉灌注亚甲蓝对直肠癌全直肠系膜切除术后患者排尿功能和性功能的改善作用。方法前瞻性纳入2013年6月至2015年6月间浙江省绍兴市人民医院收治的68例和广东省中山市陈星海医院收治的44例直肠癌患者,按随机数字表法分为试验组和对照组,每组各人组56例患者。两组患者均行全直肠系膜切除术(TME),试验组患者在游离直肠系膜前于直肠上动脉内缓慢注射1%亚甲蓝8ml观察其对TME手术区域的显示情况。比较两组患者术中淋巴结清扫情况及术后排尿功能和性功能(包括勃起功能和射精功能)。结果两组患者基线资料的差异均无统计学意义(均P〉0.05)。试验组患者较对照组手术时间缩短[(3.28±0.63)h比(4.01±0.94)h,P〈0.01],术中失血量减少[(92.5±36.4)ml比(174.1±61.4)ml,P〈0.01],淋巴结清扫数目增多[(15.8±7.6)枚比(11.9±4.3)枚,P〈0.01]。术后1年,试验组与对照组患者排尿功能Ⅰ、Ⅱ、Ⅲ和Ⅳ级者分别为33例(58.9%)、15例(26.8%)、6例(10.7%)、2例(3.6%)和24例(42.9%)、15例(26.8%)、12例(21.4%)、5例(8.9%),试验组明显优于对照组(P〈0.05);勃起功能I、Ⅱ和Ⅲ级者分别为36例(64.3%)、18例(32.1%)、2例(3.6%)和25例(44.6%)、23例(41.1%)、8例(14.3%),试验组明显优于对照组(P〈0.05);射精功能Ⅰ、Ⅱ和Ⅲ级者分别为36例(62.5%)、18例(32.1%)、3例(5.4%)和24例(42.9%)、22例(39.3%)、10例(17.9%),试验组亦明显优于对照组(P〈0.05)。结论直肠癌TME手术中动脉灌注亚甲蓝能清晰区分手术界面,减少因盆腔自主神经损伤的机会,降低术后排尿功能和性功能障碍的发生率,同时可缩短手术时间,减少术中出血,提高淋巴Objective To explore the effect of arterial infusion with methylene blue during total mesorectal excision (TME) for better preservation of pelvic autonomic nerve on urination function and sexual function in male patients with rectal cancer. Methods A total of 68 male rectal cancer patients from Zhejiang Xiaoxing People's Hospital and 44 male rectal cancer patients from Guangdong Zhongshan Chenxinghai Hospital between June 2013 and June 2015 were prospectively enrolled. Patients were randomly divided into the trial group receiving arterial infusion with 8 ml of 1% methylene blue andthe control group without artery infusion, with 56 cases in each group. All the patients underwent TME. Intra-operational lymph node removal and postoperative urination and sexual function (erection and ejaculation) were compared between two groups. Results The baseline data of the two groups were not significantly different (all P 〉 0.05). As compared to the control group, the trial group had shorter operation time [(3.28 ± 0.63) hours vs. (4.01 ± 0.94) hours, P 〈 0.01], less blood loss [(92.5 ± 36.4) ml vs. (174.1 ± 61.4) ml, P〈 0.01], and more lymph nodes harvested per patient (15.8 ± 7.6 vs. 11.9 ± 4.3, P 〈 0.01). One year after operation, class Ⅰ , Ⅱ ,Ⅲ , Ⅳ of urination was observed in 33 cases (58.9%), 15 cases (26.8%), 6 cases (10.7%), 2 cases (3.6%) in the trim group, while 24 (42.9%), 15 (26.8%), 12 (21.4%), 5 (8.9%) in the control group, which indicated that trial group was superior to control group (P 〈 0.05). Class Ⅰ , Ⅱ ,Ⅲ of erection was observed in 36 cases (64.3%), 18 cases (32.1%), 2 cases(3.6%) in the trial group, while 25(44.6%), 23(41.1%), 8(14.3%) in the control group, which indicated that trial group was superior to the control group (P 〈 0.05). Class Ⅰ , Ⅱ ,Ⅲ of ejaculation was found in 36 cases (62.5%), 18 cases (32.1%), 3 cases (5.4%) in the trial group, while 24 (
