Abstract
BACKGROUND
Portal vein injury is an uncommon complication of endoscopic retrograde cholangiopancreatography (ERCP), for which stent malpositioning in the portal vein is very rare and can lead to fatal events. We report a case of biliary stent migration to the portal vein and a novel method for its safe removal under the guidance of portal angiography. Moreover, we reviewed the literature and summarized reports on the identification and management of this condition.
CASE SUMMARY
A 59-year-old woman with pancreatic cancer presented with abdominal pain and a high fever 20 days after the placement of two plastic biliary stents under the guidance of ERCP. Blood cultures and laboratory tests revealed sepsis, which was treated with antibiotics. A contrast-enhanced computed tomography scan revealed that one of the biliary stents in the main portal vein was malpositioned. To safely remove the stent, portal angiography was performed to visualize the portal vein and to allow the management of any bleeding. The two stents were removed without obvious bleeding, and an uncovered self-expanding metal stent was placed in the common bile duct for drainage. The patient had an uneventful 6-month follow-up period, except for self-resolving portal vein thrombosis.
CONCLUSION
The combination of endoscopic and angiographic techniques allowed uneventful management of stent malposition in the portal vein.
Core Tip: Stent malpositioning in the portal vein is a very rare complication of endoscopic retrograde cholangiopancreatography and can be fatal. We report a case of stent migration into the portal vein and a novel method for its safe removal under the surveillance of portal angiography. After reviewing the literature, we summarized the characteristics of reported cases, including predisposing factors and manifestations of stent malposition in the portal vein, and other treatments, such as immediate stent removal, metal stent placement in the bile duct, urgent surgery, and covered stent placement in the portal vein.
