title: A new catheter for endoscopic manometry of Oddi's sphincter.
abstract: With a newly designed manometry catheter and a modified pull-through maneuver a high presure zone can reproducibly be recorded between the duodenum and the pancreato-biliary tree corresponding to Oddi's sphincter. Catheter marking allows in addition calculation of the length of this zone. Since the sealed end of the catheter remains during pressure recording within the ductal system repeated push-and-pull maneuvres can be performed through the sphincter area.
