Nearly all chronic anal fissures occur in the posterior midline of the anal canal. However, some of them are in the anterior midline and are rarely double or in the lateral anal walls. The aim of this study was to determine if the clinical, manometric and endosonographic characteristics in patients with chronic anal fissure varied according to topography of the fissure. The patients included in this prospective study were divided according to a fissure site in posterior midline location (Group A, n = 84) and anterior midline location (Group B, n = 30). No differences were found regarding clinical data except that anterior fissures were more common in females. Mean maximal anal resting pressure and internal anal sphincter thickness was higher in Group A. However, these differences were not statistically significant. We found correlation between mean maximal anal resting pressure and internal anal sphincter thickness in patients suffering from anterior chronic anal fissure.
几乎所有慢性肛裂都发生在肛管后中线。然而，其中一些位于前中线，很少有双侧或位于肛管侧壁的情况。本研究的目的是确定慢性肛裂患者的临床、测压和腔内超声特征是否根据肛裂的部位而有所不同。纳入这项前瞻性研究的患者根据肛裂部位分为后中线位置组（A组，n = 84）和前中线位置组（B组，n = 30）。除了前位肛裂在女性中更常见外，临床数据方面未发现差异。A组的平均最大肛管静息压和肛门内括约肌厚度较高。然而，这些差异无统计学意义。我们发现患有前位慢性肛裂的患者，其平均最大肛管静息压与肛门内括约肌厚度之间存在相关性。
