If possible, cannulate PD (and CBD) prior to ampullectomy and obtain a pancreatogram to determine the location of the pancreatic orifice |
Remember the anatomical relationship between biliary and pancreatic orifices. If imagined on a clock face, the CBD is at 11 o'clock and PD at 5 o'clock (Fig. 5) |
Attempt PD cannulation as the first manoeuvre after ampullectomy whilst visualisation is optimal |
If the PD cannot be identified then cannulate the distal aspect of the CBD with a sphincterotome and lift it up to ‘stretch’ the pancreatic orifice and improve visibility (Fig. 6) |
Be wary of underlying pancreas divisum. The benefit of stenting the ventral duct is limited and attempts to do so can be frustrating |
