The results of haemorrhoidectomy alone and anal dilatation alone for the treatment of 20 patients with second or third degree haemorrhoids were assessed prospectively over a 12-month period. After haemorrhoidectomy the symptoms of bleeding, lump, pruritus and discharge disappeared, and anal continence was maintained. Proctoscopy showed the occasional development of secondary piles high in the anal canal. Of those patients having an anal dilation alone, nearly half had symptoms and one had a mucus leak. Anal continence was unalttered in the remainder. Proctoscopy indicated the loss of anal venous engorgement.
前瞻性地评估了单纯痔切除术和单纯肛门扩张术治疗20例二度或三度痔疮患者的效果，为期12个月。痔切除术后，出血、肿物、瘙痒和分泌物等症状消失，且维持了肛门节制功能。直肠镜检查显示肛管高位偶尔会出现继发性痔。在仅接受肛门扩张术的患者中，近一半有症状，1例出现黏液渗漏。其余患者的肛门节制功能未改变。直肠镜检查显示肛门静脉充血消失。
