The effect of transanal haemorrhoidal dearterialization (THD) on continence and anorectal physiology has not yet been demonstrated.
Twenty patients suffering from 3rd degree haemorrhoids were enrolled and underwent THD, including both dearterialization and mucopexy. Clinical assessment, anorectal manometry, rectal volumetry and endoanal ultrasound were performed preoperatively and at 6 months postoperatively.
Postoperatively two and six patients had transient rectal pain and tenesmus, respectively. No patient reported faecal urgency or minor or major incontinence. All patients remained able to discriminate gas from faeces. No significant variation of the mean values of anal manometric and rectal volumetric parameters was recorded at 6 months of follow-up compared with preoperative values. At 6 months both internal and external sphincters were endosonographically intact.
THD does not cause trauma to the anal canal and rectum.
经肛门直肠动脉结扎术（THD）对控便和肛肠生理的影响尚未得到证实。
纳入 20 例 3 度痔患者，行 THD 术，包括动脉结扎和黏膜固定术。术前和术后 6 个月进行临床评估、肛肠测压、直肠容量测量和腔内超声检查。
术后 2 例和 6 例患者分别出现一过性直肠痛和里急后重。无患者报告粪便急迫感或轻度或重度失禁。所有患者仍能区分气体和粪便。与术前相比，术后 6 个月的肛门测压和直肠容量测量参数的平均值无明显变化。术后 6 个月，内外括约肌在腔内超声下均完整。
THD 不会对肛管和直肠造成损伤。
