For the first time we report about a new diagnostic technique, the endoluminal ultrasound of the colon. It enables us to examine the whole colon by an ultrasound endoscope. The ultrasound frequency of the instrument (XCF-UM2, Olympus Optical/Aloka, Japan) is 7.5 MHz, the roundview is approximately 320 degrees. The mean advantage is the combination of endoscopic inspection including biopsy and endoluminal ultrasound. First clinical experience was gained at a total of 27 examinations. It was possible to demonstrate the normal colonic wall (n = 10) in the entire large bowel, neighbouring organs could be visualized clearly and reproducibly in most cases. Pathologic findings (four carcinomas, eight polyps, five anastomoses) were correctly diagnosed by endosonography with a sensitivity of 100% and a specificity of 96%. In two cases the histopathologic work-up of the resected specimens confirmed the ultrasonographic diagnosis of malignancy, while the endoscopic biopsy indicated benign wall lesions. This suggests that endosonography may be superior to histological diagnosis by biopsy in some cases.
我们首次报道了一种新的诊断技术——结肠腔内超声检查。它使我们能够通过超声内镜检查整个结肠。该仪器（日本奥林巴斯光学株式会社/阿洛卡公司生产的XCF-UM2）的超声频率为7.5兆赫，环扫视野约为320度。其主要优点是将包括活检在内的内镜检查与腔内超声检查相结合。通过27例检查获得了初步临床经验。在整个大肠中均能显示正常结肠壁（n = 10），在大多数情况下，相邻器官能够清晰且可重复地显示。通过内镜超声检查正确诊断出病理结果（4例癌、8例息肉、5例吻合口），敏感性为100%，特异性为96%。在2例病例中，切除标本的组织病理学检查证实了超声对恶性肿瘤的诊断，而内镜活检提示为良性壁病变。这表明在某些情况下，内镜超声检查可能优于活检的组织学诊断。
