Endoluminal sonography in follow-up of rectal carcinoma.
1989
Fourteen patients who had undergone local excision, anterior resection or low anterior resection for rectal carcinoma were examined by endoscopic ultrasonography. In two of three cases of local recurrent carcinomas, endoscopic sonography was superior to computed tomography in determining the depth of tumor infiltration. There were difficulties in differentiating scar tissue from local tumor formation when the mucosa appeared normal upon endoscopic examination. Only repeated follow-up examinations starting in the postoperative period, will allow a differentiation between scar tissue and local tumor recurrence.
Endoluminal ultrasonic examination of sessile polyps and early carcinomas of the rectum
1989
The results of conventional endosonographic techniques in the assessment of early carcinomas and sessile polyps of the rectum have been unsatisfactory. We therefore developed a new technique in which the rectal cavity is filled directly with water. Using this technique, the anatomy of small rectal tumors is preserved and the layers of the rectal wall are easier to differentiate, especially with a 10-MHz scanner. The clinical results in 66 patients demonstrate that this new technique is very accurate in the preoperative staging of adenomas and T1-carcinomas of the rectum.
