| Popis: | PURPOSE Evaluation as to whether diagnosis of large bowel disease and TNM staging of colorectal carcinoma are possible by colorectal hydrosonography (HUS). METHOD 52 patients with suspected neoplastic or inflammatory large bowel disease, underwent HUS. Before performing abdominal ultrasound, the colon was filled with fluid. Morphological alterations of the bowel wall were judged benign or malignant. Colorectal carcinomas were classified according to the TNM system. RESULTS Laparotomy was performed in 46 of 52 patients. Correlation with surgery and histopathology showed that 77% of morphologic alterations of the colonic wall were detected by HUS. While benign lesions of the colonic wall occasionally mimicked malignant disease, colonic carcinomas were reliably diagnosed by HUS, because destruction and invasion of the bowel wall was visible. Carcinomas of the lower part of the rectum, however, were missed in most cases. Accuracy to determine the infiltration depth of colorectal carcinomas was 89%, but hydrosonographic N-staging was unreliable. Inflammatory disease of the large bowel as well as changes complicating the inflammatory bowel disease were accurately diagnosed by HUS. CONCLUSION In selected patients, colorectal HUS is suited for diagnosis and staging of colonic tumours. It also helps to evaluate inflammatory bowel disease, because small and large bowel can be reliably distinguished from each other and the degree of stenosis of inflamed colonic segments becomes visible. Furthermore, HUS increases the visibility of fistulas. |
