FIG3
Esophagogastroduodenoscopy finding (A and B) and abdominal X-ray (C).. Folds convergence caused by tumor invasion was confirmed in the third portion of the duodenum (A, white arrow). The SEMS was placed beyond the stenosis caused by tumor invasion in the third portion of the duodenum (B and C, white arrow).

Therefore, the PCFQ260AZ endoscope (Olympus, Tokyo, Japan), which is longer than the GIF-Q260 J endoscope, was chosen to place the SEMS. The PCFQ260AZ endoscope was able to reach the stenosis, and a 22 mm x 80 mm uncovered SEMS (Niti-S, Taewoong Medical, Seoul, South Korea) was placed beyond the stenosis (Figure 4A-4C).
