“…Endoscopic intervention is rarely feasible due to the Roux‐en‐Y reconstruction, and surgical treatment is associated with high risks. To date, percutaneous radiological approach is usually the primary, safe, and effective procedure for the management of the high‐grade biliary stenosis . If the recanalization of the bilio‐enteric anastomosis stricture is unsuccessful at first attempt, placement of the EBD usually allows at least the decompression of the intrahepatic biliary system.…”

“…If the recanalization of the bilio‐enteric anastomosis stricture is unsuccessful at first attempt, placement of the EBD usually allows at least the decompression of the intrahepatic biliary system. During the subsequent procedure, the anastomosis can usually be crossed with the guide‐wire, and eventually after a balloon dilatation session, an EIBD can be placed . However, multiple sessions of interventional radiology procedures are usually necessary for several months to obtain and ensure a good trans‐anastomotic bile flow .…”

Anastomotic BO is a common complication of pediatric LT, particularly for split liver, with an incidence of 10%-35% and high morbidity. 1-3 If not treated, BO could evolve toward secondary biliary cirrhosis and re-transplantation. 1 Because the endoscopy is generally infeasible in the Roux-en-Y, percutaneous interventional radiology management is usually the safest and most effective approach to avoid surgical revision of a stenotic bilio-enteric anastomosis. [1][2][3][4] We report the case of a child with partial LT and severe occlusion of the HJ non-crossable with conventional interventional radiological techniques. A new biliodigestive communication was performed via percutaneous transhepatic approach using the transseptal puncture system. AbstractStenosis of the HJ is a common complication of pediatric split LT with high morbidity and possible evolution to secondary biliary cirrhosis and re-transplantation if not treated.

“…8 Sharp needle recanalization using a Colapinto needle has been reported in several cases, and in these jejunal access was usually obtained and the puncture done blindly, or by placing an inflated balloon that was used as a target. [10][11][12][13][14] In a few cases report, a radiofrequency wire was used in recanalization of complete obstruction where conventional methods had failed in five patients. This is an alternative method for patients with biliary obstructions and isolated ducts, but the radiofrequency wire is not readily available and can be problematic with false lumen passages.…”

A B S T R A C TBackground: To describe our experience with percutaneous small bowel access in patients with surgically altered anatomy for complex biliary intervention where cone-beam computed tomography (CBCT) was used to confirm appropriate small bowel access. Methods: Retrospective chart review from January 2012 to February 2016 identified 9 patients who underwent complex biliary procedures, which used CBCT assistance. Inclusion criteria were creation of percutaneous small bowel access, usage of CBCT, and biliary recanalization. Procedures were performed using percutaneous small bowel access to assist with antegrade or retrograde biliary recanalization using a variety of wire and catheter techniques. Non-contrast CBCT was used in all cases to confirm appropriate small bowel access. Results: In three patients with disconnected biliary systems and failed prior attempts at percutaneous recanalization, new bilio-enteric anastomoses were successfully created. In 6 patients with prior hepaticojejunostomy and biliary obstructions, percutaneous jejunostomy was used successfully to recanalize the biliary stenoses and place multiple internal biliary stents, which were then managed with percutaneous retrograde exchanges. Five patients are catheter free; two are currently managed with long-term biliary drainage. One patient eventually required liver transplantation and another required surgical revision of anastomotic restenosis. There was a single major complication in one patient where the jejunostomy tube resulted in small bowel obstruction requiring surgical revision. A minor complication occurred in another patient, with the development of cellulitis around the jejunostomy tube. Conclusion: CBCT can effectively confirm appropriate percutaneous small bowel access in patients with surgically altered anatomy, and who require retrograde biliary recanalization. CBCT is also useful to guide percutaneous creation of new bilio-enteric anastomosis in patients with disconnected biliary systems.

Fibrotic central venous occlusions in patients with thoracic malignancy and prior radiotherapy can be impassable with standard catheters and wires, including the trailing or stiff end of a hydrophilic wire. We report two patients with superior vena cava syndrome in whom we successfully utilized a radiofrequency guide wire (PowerWire, Baylis Medical, Montreal, Quebec, Canada) to perforate through the occlusion and recanalize the occluded segment to alleviate symptoms.
