| definition |
肛是肛管，裂是裂开，肛裂是消化道出口从齿状线到肛缘这段最窄的肛管组织表面裂开，形成小溃疡，方向与肛管纵轴平行，呈梭形或椭圆形，长约0.5～1.0cm，常引起肛周剧痛。肛裂最常见的部位是肛门的前后正中，以后正中为多。肛裂的发病率约占肛肠病的20%，多以年轻人为主，但肛裂更青睐女性，尤其是年轻女性。我国女性发病率约是男性的1.8倍，日本大肠肛门会志报告的结果是1.6倍。肛裂有急性和慢性之分，慢性肛裂由于病程长和反复发作，裂口上端的肛门瓣和肛乳头水肿，造成肛乳头肥大，下端皮肤呈袋状垂向下突出于肛门外，形成“前哨痔”，肛裂、前哨痔、肛乳头肥大常同时存在，称为肛裂三联征。 肛裂又称裂痔，钩肠痔是一种发病率极高的肛肠疾病。肛裂是指肛管皮肤全层裂开，并形成慢性溃疡的一种疾病。好发于肛门前后正中，多见于后正中。临床以周期性肛门疼痛、大便带血、便秘为特点。 An anal fissure is a break or tear in the skin of the anal canal. Anal fissures may be noticed by bright red anal bleeding on toilet paper and undergarments, or sometimes in the toilet. If acute they are painful after defecation, but with chronic fissures, pain intensity often reduces. Anal fissures usually extend from the anal opening and are usually located posteriorly in the midline, probably because of the relatively unsupported nature and poor perfusion of the anal wall in that location. Fissure depth may be superficial or sometimes down to the underlying sphincter muscle. Untreated fissures develop a hood-like skin tag which cover the fissure and cause discomfort and pain. A painful linear tear at the margin of the anus. It appears as a crack or slit in the mucous membrane of the anus and is very painful and difficult to heal. |
