Fifty consecutive outpatients with bleeding internal hemorrhoids were prospectively treated with a single application of rubber band ligation or infrared coagulation. Complete follow-up observation was obtained in 48 patients (23 underwent rubber band ligation and 25 underwent infrared coagulation). At one month after treatment, 22 patients who underwent rubber band ligation and 16 who underwent infrared coagulation, were symptomatically improved (p less than 0.05). At six months, 15 patients who had undergone rubber band ligation and ten who had infrared coagulation treatment, remained improved (p less than 0.05). There was no statistical difference in the discomfort experienced by either group during or after the procedure as determined by a self-assessment scale. Two patients who underwent rubber band ligation experienced complications--a thrombosed external hemorrhoid developed in one patient and another had delayed rectal bleeding. Although associated with occasional complications after treatment, rubber band ligation is more effective than in infrared coagulation for single session treatment of bleeding internal hemorrhoids.
五十例连续性出血性内痔门诊患者前瞻性地接受了单次橡皮圈套扎术或红外线凝固术治疗。48例患者获得了完整的随访观察(23例行橡皮圈套扎术,25例行红外线凝固术)。治疗后1个月,22例行橡皮圈套扎术的患者和16例行红外线凝固术的患者症状改善(p<0.05)。6个月时,15例行橡皮圈套扎术的患者和10例行红外线凝固术的患者仍有改善(p<0.05)。根据自我评估量表,两组在手术期间或术后经历的不适无统计学差异。2例行橡皮圈套扎术的患者出现并发症——1例患者发生血栓性外痔,另1例出现延迟性直肠出血。尽管治疗后偶尔会出现并发症,但橡皮圈套扎术在单次治疗出血性内痔方面比红外线凝固术更有效。
