Polypectomy after submucosal adrenalin injection
polypectomy after submucosal adrenalin injection polypectomy after submucosal adrenalin injection
Sessile sigmoid adenoma. Prior to polypectomy the surrounding submucosa is infiltrated with an adrenalin preparation (1:20000). This entails a separation of the mucosa from the submucosa and facilitates safe resection of the polyp. In the left picture the polyp sort of "swims" on the injected submucosal cushion. The mucosa is pale as consequence of the adrenalin- induced vasoconstriction. To the right: The polyp is resected. The vessels are still maxuimally constricted, which minimizes the danger of post- resection hemorrhage.

polypectomy after submucosal adrenalin injection A second example shows a polyp with a short stalk. After injection of adrenalin into the base of the stalk, the mucosal layer gets lifted (top right). Thereafter the polyp can be resected safely and "in sano"(bottom).
