Hemorrhage from bile duct varices treated with fully covered expandable metallic stent placement in pancreatic carcinoma

Portal vein stenting blocked the inflow tract and completely resolved bile duct varices, formed by cavernous transformation of the portal vein

There is no established treatment for bleeding bile duct varices (BDVs). We report the first case of portal vein (PV) stenting completely eradicating bleeding BDVs. A 70-year-old male with malignant lymphoma developed BDVs due to PV obstruction, which had caused compression and stricture of the distal bile duct. Endoscopic retrograde cholangiography was performed to evaluate the stricture and bleeding from the ruptured BDV was observed. Endoscopic hemostasis was difficult, requiring reopening of the extra-hepatic PV and reducing the blood flow to the BDVs for hemostasis. Therefore, PV stenting was performed. During the procedure, portal angiography confirmed an inflow tract to the BDVs. Therefore, covered stents were placed in the PV and adjusted to block the inflow tract to the BDVs at the distal end. After stenting, the BDVs were successfully blocked and all PV blood flowed through the stent placed in the extra-hepatic PV. Two weeks after stenting, the BDVs had disappeared completely and the bleeding has not recurred for months. We experienced a case in which PV stenting not only reopened an obstructed PV but also successfully occluded the inflow tract. This case demonstrates the potential of PV stenting for the treatment of hemorrhagic BDVs.

The Dramatic Haemostatic Effect of Covered Self-expandable Metallic Stents for Duodenal and Biliary Bleeding

Bilio-duodenal bleeding, such as post-endoscopic sphincterotomy (EST) bleeding, common bile duct (CBD) bleeding after endoscopic retrograde cholangiopancreatography (ERCP), and duodenal bleeding due to malignant tumour invasion, can sometimes become severe. Six cases of refractory bilio-duodenal bleeding were stanched via covered self-expandable metallic stent (CSEMS) insertion, even though three of the patients had a history of gastrectomy. The dumbbell-shaped CSEMS was useful for managing post-EST bleeding. Additional duodenal CSEMS insertion was useful for the patient who had previously undergone uncovered SEMS insertion, and no migration of the CSEMS was observed. CSEMS insertion was useful for treating refractory bilio-duodenal haemorrhaging.
