Intraduodenal Cannulation in a Rat Model for Immunopathology Studies

This video demonstrates intraduodenal cannulation in a rat model. After anesthetizing the rat, the duodenum is located and a small puncture is created. A J-shaped cannula with a beveled tip is carefully inserted and secured, and the incision is closed. The cannulated rat model enables intra-intestinal infusion for immunopathology studies.
