Summary

Pancreatic pseudocysts and walled-off pancreatic necrosis are local complications of acute and chronic pancreatitis. Their treatment, if indicated, consists of percutaneous, surgical or endoscopic drainage. In recent years, the increasingly preferred option is endoscopic ultrasound-guided transmural drainage for fluid collection. A relatively rare complication is the migration of an introduced stent after endoscopic drainage. We present a 52-year-old patient with chronic pancreatitis and a symptomatic pseudocyst, for which treatment by endoscopic pseudocystogastrostomy with a fully covered self-expanding metal stent was complicated by the development of a pneumoperitoneum. After surgical revision, the presence of an originally introduced stent in the residual pseudocyst was detected by imaging techniques and was subsequently successfully extracted by endoscopy through the newly introduced metallic  stent.
