Abstract
Endoscopic resection techniques using snare polypectomy with or without submucosal
saline injection have also been applied to resect smaller duodenal carcinoid tumors.
We report on two patients where endoluminal ultrasound using a small diameter probe
was used to visualize the adherence of the carcinoids to the underlying wall layers
and the scperating effect of subtumoril saline injection. One patient, in whom a clear
separation between the tumor and the underlying tissue after saline injection was
visualized, underwent successful endoscopic resection. In the other patient no clear
separation could be achieved after saline injection and the patient underwent surgical
removal of his tumor; both tumors were 1 cm or less in their maximal diameter.
