A patient in his 50's was referred to our hospital for the treatment of infected WON. He had been diagnosed with severe acute pancreatitis 3 months before. EUS-guided drainage with placement of a straight PS and nasal cystic drainage tube was performed, but the straight PS migrated proximally into the WON during the procedure. A metallic stent was placed 10 days later, and it reduced the size of the cavity. The metallic stent was retrieved 2 weeks later, and three pigtail PSs were inserted. He was referred to our hospital again with abdominal pain 11 months later. CT revealed penetration of the straight PS, which had originally been inserted through the horizontal part of the duodenum, and the three PSs through the duodenal bulb. The migrated straight PS and 2 of the 3 pigtail PSs were retrieved.
