Anal Fissure: 症状、诊断和治疗

English | 2012 | ISBN: 1612097162 | 142 Pages | PDF | 2.3 MB

The presence of an anal fissure is reliably associated with an elevated intra-anal pressure and decreased blood flow to the anoderm. Symptoms include pain, bleeding, pruritus and soiling. Greater than 90% of acute anal fissures are of short duration and heal spontaneously or with simple measures. A high-fibre diet with an increased intake of water is recommended, laxatives may be used when required to soften constipated stool and warm sitz baths may offer symptomatic relief. Acute fissures that fail to heal become chronic fissures, which have traditionally been treated by surgery. This book presents and discusses recent developments on anal fissure conservative medical and surgical treatment, as well as the management of surgical complications.

肛裂的存在与内括约肌压力升高和皮肤动脉血流减少密切相关。症状包括疼痛、出血、瘙痒和排便失禁。超过90%的急性肛裂病程较短且能自行痊愈或通过简单措施治愈。建议采用高纤维饮食并增加饮水量，需要时可使用泻药软化便秘粪便，温水坐浴可能提供症状缓解。未能愈合的急性肛裂会发展为慢性肛裂，这通常通过手术治疗。本书介绍了和讨论了肛裂保守医疗与外科治疗的最新进展，以及外科并发症的管理。
