´FORGOTTEN´ RETROPERITONEAL DOUBLE-PIGTAIL PLASTIC STENT CAUSING COLONIC FISTULIZATION AND ANEMIA 6 YEARS LATER: ENDOSCOPIC REMOVAL

A 72-years-old man suffering from iron deficiency anemia who had undergone an EUS-guided transgastric pseudocyst drainage with double-pigtail plastic stents 6 years earlier. During the procedure, one stent migrated into the pseudocyst and decisition was to leave it in place. Patient remained asypmtomatic for 6 years, then he developed anemia. Colonoscopy found the stent penetrating into the descending colon. After a CT-scan showing no complications, a new colonoscopy was performed for stent removal and wall defect closure with Ovesco clip.

Conclusions

1. Extralumenal migrated stents must be retrieved to prevent late complications

2. Endoscopic removal may be a first-line treatment
