Percutaneous internal drainage in obstructive jaundice [PDF]

open access: yesAmerican Journal of Roentgenology, 1980
In eight patients with inoperable obstructive jaundice, an endoprosthesis was inserted percutaneously through the obstruction to allow internal drainage of bile to the bowel. The method offers several advantages over external percutaneous drainage and is warranted in selected cases.

Spontaneous internal drainage of pancreatic pseudocysts [PDF]

open access: yesAmerican Journal of Roentgenology, 1976
Six cases are reported in which spontaneous internal drainage between a pancreatic pseudocyst and the alimentary tract became established. In each instance the communication was demonstrated radiologically. The clinical circumstances and radiographic features of these cases are described, and the existing literature pertaining to this phenomenon is ...

PREVENTION OF PURULENT CHOLANGITIS AFTER PERCUTANEOUS ENDOBILIARY TRANSPAPILLARY DRAINAGE IN PATIENTS WITH OBSTRUCTIVE JAUNDICE

open access: yesУчёные записки Санкт-Петербургского государственного медицинского университета им. Акад. И.П. Павлова, 2019
Introduction. The incidence of cholangitis varied from 9 % to 33 % after the insertion of transpapillary external-internal endobiliary drainage. In case of proximal bile obstruction, the method of suprapapillary insertion of external-internal drainage ...
