Transanal haemorrhoidal dearterialisation is a non-excisional surgical method for the treatment of haemorrhoidal disease. It uses a Doppler ultrasound probe to accurately identify the site to suture-ligate the piles, resulting in a decrease in the arterial inflow to the piles and their subsequent regression.
A total of 140 consecutive patients who underwent transanal haemorrhoidal dearterialisation were studied. The number and locations of the haemorrhoidal arteries were documented. The presenting symptoms and their subsequent resolution were noted.
The median number of haemorrhoidal arteries ligated was four. Seventy-five patients (53.6%) had four haemorrhoidal arteries ligated. A total of 82 patients (58.6%) had a 'fourth' haemorrhoidal artery in the left anterior one o'clock position. Symptoms of bleeding, prolapse, pain and itching resolved in 92, 65, 68 and 60% of patients who presented with the respective symptoms preoperatively.
There is a fourth haemorrhoidal artery consistently found in the left anterior one o'clock position. Adequate treatment of this artery minimises the recurrence of haemorrhoidal symptoms.
经肛门直肠动脉结扎术是一种非切除性手术方法，用于治疗痔病。它使用多普勒超声探头准确识别要缝合结扎的痔的部位，从而减少痔的动脉流入量，使其随后消退。
研究了 140 例连续接受经肛门直肠动脉结扎术的患者。记录了痔动脉的数量和位置。记录了患者的主要症状及其随后的缓解情况。
结扎的痔动脉中位数为 4 条。75 例（53.6%）患者结扎了 4 条痔动脉。共有 82 例（58.6%）患者在左侧前 1 点位置有“第 4 条”痔动脉。术前有出血、脱垂、疼痛和瘙痒症状的患者中，分别有 92%、65%、68%和 60%的患者症状得到缓解。
在左侧前 1 点位置始终存在第 4 条痔动脉。充分治疗这条动脉可以最大限度地减少痔症状的复发。
