Increased understanding of the anatomy of haemorrhoids has led to the development of new procedures to treat them. Among the surgical options for intractable prolapsed haemorrhoids, formal haemorrhoidectomy now competes with stapled haemorrhoidopexy, which is less painful and allows a shorter convalescence but may have a higher recurrence rate and needs further long term evaluation
对痔疮解剖结构的深入了解促使了治疗痔疮新方法的发展。在治疗顽固性脱垂性痔疮的手术选择中，传统痔切除术如今要与吻合器痔上黏膜环切术竞争，后者疼痛较轻，康复期较短，但复发率可能更高，需要进一步进行长期评估。
