213 patients, classified in 3 groups, were examined in a prospective trial using endorectal ultrasound. 80 patients (group A) had no anorectal disease, the endorectal ultrasound showed normal structures of the anorectum and the perirectal tissue. 80 patients (group B) suffered from Crohn's disease, 30 of them had no clinical signs, the rest of this group (50 patients) felt pain in the anal/perianal region. 83 patients (group C) had perianal abscesses or fistulas, Crohn's disease could be excluded. In all 64 perianal fistulas and 66 perianal abscesses were diagnosed. The results of the rectal-proctological examination were compared with endorectal ultrasound. 100% of the perianal abscesses could be recognized using endosonography. The digital-proctological examination revealed only 57% of perianal abscesses and 48% of perianal fistulas; the supralevatory abscesses couldn't be detected proctologically at all. By endorectal ultrasonography we obtained useful informations about localization and extension of the inflammatory process. From a therapeutic and prognostic view the endorectal ultrasound is a simple, practicable and useful method to investigate perianal and anorectal diseases.
在一项前瞻性试验中，对213名分为3组的患者进行了直肠内超声检查。80名患者（A组）无肛肠疾病，直肠内超声显示肛管直肠及直肠周围组织结构正常。80名患者（B组）患有克罗恩病，其中30人无临床症状，该组其余50名患者有肛门/肛周区域疼痛。83名患者（C组）患有肛周脓肿或肛瘘，可排除克罗恩病。共诊断出64例肛周瘘和66例肛周脓肿。将直肠-直肠病学检查结果与直肠内超声检查结果进行比较。使用腔内超声可识别100%的肛周脓肿。直肠指检仅发现57%的肛周脓肿和48%的肛周瘘；直肠指检根本无法检测到直肠上间隙脓肿。通过直肠内超声检查，我们获得了有关炎症过程的定位和范围的有用信息。从治疗和预后的角度来看，直肠内超声是一种简单、可行且有用的检查肛周和肛管直肠疾病的方法。
