Transhepatic Assisted Transoral Placement of a Duodenal Stent in Malignant Gastric Outlet Obstruction

Gastric outlet obstruction is a well- recognized complication of locally advanced carcinoma of the head of the pancreas. The authors report a transoral placement of a duodenal stent over a percutaneous guide wire, inserted retrogradely through a transhepatic approach via the ampulla of Vater, in a patient in whom traditional stent placement was technically not possible. This technique allows safe duodenal stent placement for different malignant gastric outlet obstruction such as pancreatic, gastric, duodenal, and metastases to the peripancreatic region.
