A. Upper gastrointestinal study performed before stent placement shows stricture in the pylorus of the stomach (arrow).
B. The spot radiograph obtained during the procedure shows failure of advancing the stent introducer (arrows) beyond the stricture due to severe gastric distension. Note the PTBD catheter (arrowhead) that had been placed before the procedure.
C. Gastric wall puncture was made with an 18G seldinger needle, and guide wire and 5-Fr vascular catheter are inserted to negotiate through the stricture. Notice the T-fastener (arrow) and the nasogastric tube (arrowheads).
D. After successful negotiation of the stricture with the vascular catheter and guide wire, and then exchange with an extra-stiff guide wire, a dual stent (arrows) is successfully placed over the wire.
E. Additionally, a 14-Fr gastrostomy tube is inserted through the transgastric tract.
F. Upper gastrointestinal study obtain 2 days after the procedure shows good contrast flow through the stent.
