Between July 1991 and November 1993 106 patients have been examined by endoanal ultrasound with a 7.0 MHz transducer and a special hard plastic cone which is attached over the transducer. Indications for endoanal ultrasound have been anal carcinoma, perirectal or perianal fistulas, perianal abscesses and sphincter insufficiencies. All anal carcinomas and 2 anal cancer recurrences could be visualized with regard to their size and extension as well as the lymphnode infiltration. 28 of 35 fistulas have been seen by endoanal ultrasound. Endosonographical differentiation in inter- (10), trans- (12) extra- (1) or suprasphincteric (5) was possible in all detected fistulas and confirmed by operation in 27 of 28 cases. 34 cryptogen abscesses could be detected (15 intersphincteric, 12 ischiorectal, 7 pelvirectal) and confirmed by the operative situs with regard to their size and localisation. In 9 patients with a myogen sphincter insufficiency the morphological defect of the sphincter muscle could be localized by endoanal ultrasound and confirmed by the operative situs in all cases.
1991年7月至1993年11月期间，使用7.0兆赫探头和连接在探头上的特殊硬塑料圆锥体，对106例患者进行了肛管超声检查。肛管超声检查的适应症包括肛管癌、直肠周围或肛周瘘、肛周脓肿和括约肌功能不全。所有肛管癌及2例肛管癌复发灶均可通过超声检查显示其大小、范围及淋巴结浸润情况。35例肛瘘中有28例通过肛管超声检查被发现。所有检测到的肛瘘均能通过超声内镜进行括约肌间（10例）、经括约肌（12例）、括约肌外（1例）或括约肌上（5例）的鉴别诊断，28例中有27例经手术证实。34例隐源性脓肿（15例括约肌间脓肿、12例坐骨直肠窝脓肿、7例盆腔直肠脓肿）通过超声检查得以发现，并经手术部位证实其大小和位置。9例肌源性括约肌功能不全患者，其括约肌肌肉的形态学缺陷通过肛管超声得以定位，所有病例均经手术部位证实。
