ERCP performed 2 days later detected a large peri-ampullary diverticulum and a copious amount of purulent material coming out from the peri-ampullary perforation (Fig. 1a). Fr, 5 cm) was inserted into the bile duct, and concomitantly a single pigtail (5 Fr, 4 cm) was inserted into the main pancreatic duct. Fibrin sealant (Tisseel) (Fig. 1b) was then injected to occlude the perforation.
Computed tomography-guided pigtail insertion to the right pararenal space.

On the same day, under CT guidance, a 7-Fr pigtail was inserted into the right pararenal space to drain the retroperitoneal abscess (Fig. 2a). CT scan obtained immediately after the procedure showed no complications. CT performed on the following day revealed a correctly positioned pigtail (Fig. 2b).

CT scan was repeated (Fig. 3a); this CT scan revealed migration of the pigtail catheter from the right pararenal space into the ascending colon. Colonoscopy (Fig. 3b) showed a pigtail catheter tip in the lumen of the ascending colon.
