Endoscopically performed papillotomy
The endoscopic papillotomy (EPT) (Latin papilla = bud, wart, vesicle; Greek tome = incision) is a therapeutic procedure in the field of gastroenterology .
It is used in the context of an endoscopic retrograde cholangiopancreatography (ERCP) gallstones to pass through the main bile duct (ductus hepatocholedochus) and its largest constriction the father's papilla (papilla vateri) or to ensure the outflow of bile in the case of scarred changes in the papilla . Even rare congenital malformations in the area of the bile duct opening ( choledochoceles , inner duodenal diverticulum ) can be split endoscopically with a papillotome.
During the procedure , the sphincter muscle of the father papilla (Musculus sphincter Oddi) is severed with the help of a papillotome , an electric knife that is presented through the instrument channel of the endoscope .
The procedure was first described in 1972 by L. Demling at the University of Erlangen. The endoscopic has now usually replaced the open-surgically performed transdduodenal papillotomy .
