A Study of Endoscopic Ultrasonography in the Use of Ultrasonic Probe : By Jelly Infusion Method

We studied the usefulness of a jelly infusion method in comparison with the ultrasonography by the traditional water infusion method for colorectal lesions. From October 1993 to May 1994, ultrasonic probes by jelly infusion method (UM-1W 7.5 MHz, MP-PN15-06 15MHz) were performed in 28 cases. This new method was easy to handle because the jelly stayed in the lesion of the examination, and therefore, the position change of patient was not necessary. Concerning to the diagnostic ability, diagnostic accuracy of depth of the cancer was 69.6% (early cancer 90%, advanced cancer 53.8%) . In conclusion, this method seems to be efficient and useful in ultrasonic diagnosis of colorectal lesions.
