摘要 重度痔病是肛肠外科疑难问题之一,包括Ⅲ、Ⅳ度环状内痔,Ⅲ、Ⅳ度环状混合痔。内痔核长期反复脱出,导致肛门括约肌松弛、收缩乏力,脱出内痔还纳困难,反复脱出的痔组织和肛门及内裤的摩擦,又引发痔组织水肿、增生,导致还纳更加困难,形成恶性循环。临床上可见肛周外痔静脉曲张或皮赘隆突、内痔痔核及直肠黏膜外翻、痔核肿胀、溃烂、疼痛剧烈、便血及溢液等症状。一般认为,重度痔病具有生理功能和病理解剖的不可逆性,非手术治疗效果不佳,易反复发作,多数需要接受手术治疗。目前,针对重度痔病可选择的手术方式包括:环切术、Milligan-Morgan 术、吻合器痔上黏膜环切术、痔动脉结扎术+黏膜固定术等。每一种治疗方式都有本身的优势和不足,损伤大的术式复发率低但术后疼痛程度及并发症率高,而损伤小的术式术后疼痛程度低但复发率高,不存在一种术式适合所有情况。因此,在治疗中应综合痔病的严重程度以及患者的自身情况,制定个体化治疗方案。
