定义
痔疮是肛管壁和/或肛门周围皮肤下直肠静脉丛肿胀的解剖学结构。痔疮一词通常与痔疮引起的症状有关，当痔疮肿大、发炎、血栓形成或脱垂时，导致出血和疼痛肿胀。痔疮根据脱垂的程度进行分类，尽管这可能并不总是反映症状的严重程度。
Haemorrhoids are anatomical structures of swollen veins of the rectal plexus in the walls of the anal canal and/or under the skin around the anus. The term haemorrhoids is usually related to the symptoms caused by haemorrhoids resulting in bleeding and painful swelling when they become enlarged, inflamed, thrombosed, or prolapsed. Haemorrhoids are classified according to the degree of prolapse, although this may not always reflect the severity of symptoms.
