| 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.

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).
