目的 观察改良多普勒超声引导下痔动脉结扎术(DG-HAL)治疗痔病的临床疗效.方法 将80例Ⅱ～Ⅲ期内痔患者随机分为治疗组和对照组,每组各40例,治疗组采用改良DG-HAL术,对照组采用外剥内扎术(Milligan-Morgan hemorrhoidectomy)进行治疗.观察两组术后症状改善情况及并发症等.结果 两组患者术前症状均得到有效控制,治疗组术后便血情况改善程度优于对照组,术后首次排便和术后1周便血情况比较,差异均有统计学意义(P＜0.05);治疗组术后疼痛评分均低于对照组,术后当天及术后第3天疼痛评分比较,差异均有统计学意义(P＜0.05).治疗组术后水肿评分低于对照组,差异有统计学意义(P＜0.05).结论 改良DG-HAL术治疗Ⅱ～Ⅲ期内痔具有操作简单、安全有效、微创及恢复快等优点.%Objective To observe the clinical efficacy of improved doppler - guided hemorrhoid artery ligation ( DG - HAL ) in the treatment of hemorrhoids. Methods 80 patients with Grade II or M of internal hemorrhoids were randomly divided into two groups: treated group ( n = 40 ) receiving improved doppler - guided hemorrhoid artery ligation and control group ( n = 40 ) receiving Milligan - Morgan hemorrhoidectomy. The symptom improvement and postoperative complications were observed and compared between two groups. Results All patients gained some improvement after operation, but the improvement degree of hemorrhoidal bleeding in treated group was better than that in control group and the differences in the first defecating time and one week after operation between the two groups were significant ( P <0. 05 ). The postoperative pain scores of patients in treated group were lower than those in control group and the differences on the operative day and on the 3rd day after operation between the two groups were significant ( P <0. 05 ). The postoperative edema degree of the patient in treated group was milder than that in control group ( P < 0. 05 ). Conclusion The improved doppler - guided hemorrhoid artery ligation is a safe and effective method in the treatment of grade II or IH of internal hemorrhoids, which has advantages of easy operation, minimal invasion and early recovery.
