肛瘘的临床表现为局部反复流脓、疼痛、瘙痒,一般由原发性内口、瘘管和外口组成.高位复杂性肛瘘由于治疗难度大,复发率高,治疗较为棘手,在术中需正确处理高位瘘管和内口.笔者检索了近20年国内外文献,结合科室团队的临床实践经验,从高位肛瘘的内口处理、瘘管管道处理和深部腔隙处理三个角度,就腺源性高位复杂性肛瘘的手术治疗研究进展进行综述.

研究磁共振成像(MRI)对健康男性和女性盆底组织结构三维重建的方法及意义.选取健康青年男性及女性各1人,进行MRI扫描,观察盆底部分组织结构,应用医学图像处理软件ITK-SNAP进行三维重建,建立盆底肌群的三维几何模型,并实现任意角度观察和精确定位测量分析.在此基础上,应用有限元程序ANSYS workbench,建立计算模型,并对计算结果进行拟合分析,得到耻骨直肠肌收缩力与肛直角角度变化的相关性,研究结果可为今后开展盆底相关疾病的研究提供参考依据.

Hemorrhoid disease（HD） is one of the most common clinical benign diseases,which prevalence rates vary from4%～55% over the world.Treatment of HD increases,the financial burden.For those patients who do not.respond to conservative treatment,outpatient clinic procedure or surgical treatment would be necessary.Comparation of the recent practice guidelines（or consensus） of 11 countries shows high consistency in the classification,diagnosis and treatment of hemorrhoid disease.While there are still some differences due to different cultural and insurance factors.In Asian countries like China and Japan,there are more conservative treatment methods.Meanwhile,there are more office treatment methods in western countries.
