【目的】探讨经直肠彩色多普勒超声与经直肠超声造影在痔疮动脉结扎术中的应用价值。【方法】收集痔疮患者80例，随机分为经直肠超声多普勒痔血管定位组（对照组）和经直肠超声造影痔血管定位组（观察组），每组40例，比较两组痔动脉显示率及术后症状改善情况及并发症等。【结果】观察组痔动脉显示率为95．7％，显著高于对照组85．0％（P ＜0．05）；观察组便时疼痛评分、便时出血评分、创面水肿评分、复发率均显著低于对照组（P ＜0．05）；两组排便通畅度评分、住院时间、治愈率比较无统计学意义（P ＞0．05）。【结论】经直肠超声造影痔动脉显示率高于单纯超声检测，在其指导下结扎痔动脉治疗痔疮安全有效，且操作简便、疼痛轻微、并发症少，值得临床推广应用。“,”[Objective] To explore the application value of transrectal color Doppler ultrasound and con‐trast enhanced transrectal ultrasound in hemorrhoid artery ligation .[Methods] Retrospective analyses were conducted for the clinical data of 80 patients of anorectal hemorrhoids from January 2014 to May 2015 .They were randomized into two groups of transrectal ultrasound Doppler hemorrhoidal vessel location (study) and contrast‐enhanced transrectal ultrasound hemorrhoidal vessel location (control) ( n = 40 each) .The display rate of hemorrhoidal artery ,postoperative symptoms and complications were compared .[Results] For study and control groups ,hemorrhoidal artery display rate was (95 .7% vs 85% ,χ2 =3 .914 ,P =0 .048);curative rate (95 .7% vs 85% ,χ2 =3 .914 ,P =0 .048);bowel patency score [(1 .21 ± 0 .32 vs (1 .32 ± 0 .28) ,χ2 =1 .636 ,P =0 .106];pain score [(2 .52 ± 0 .52) vs (3 .97 ± 0 .48) ,χ2 =12 .959 ,P =0 .000] ,bleeding score [(1 .56 ± 0 .68) vs (2 .34 ± 0 .73) ,χ2 =4 .979 ,P =0 .000] ,wound edema score [(1 .42 ± 0 .83) vs (2 .13 ± 0 .74) ,χ2 =4 .038 ,P =0 .000] ,hospitalization duration [(9 .23 ± 3 .67) vs (9 .37 ± 3 .36) days ,χ2 =0 .178 , P =0 .859] .During a follow‐up period of 7~28 months ,the rate of recurrence was 17 .5% [2 .5% ,χ2 =5 .000 ,P =0 .025] .[Conclusion] Hemorrhoid artery ligation under contrast‐enhanced transrectal ultrasound is both safe and effective in the treatment of hemorrhoids .It offers multiple advantages of simple operation , milder pain and fewer complications .And it is worthy of wider clinical applications .
