Mashicage Benign postoperative biliary strictures: Current protocols for percutaneous treatment of BAS are varied in their technique and success rates. Transhepatic dilatation of choledochoenterostomy strictures.

Balloon dilation is usually performed until abolition of the waist is observed. This requires adequate patient education and motivation. This protocol is similar to that used by Schumacher et al 28 and Weber et al, 14 with treatment failure rates of D Completion cholangiogram showing resolution of the stricture post stent removal. A single treatment consists of one or multiple dilation sessions separated by intervals of catheter stenting. J Vasc Interv Radiol.

First, because of the embedded blades, anxstomosis must be taken by the operator when handling the balloon catheter outside of the patient. Get free access to newly published articles Create a personal account or sign in to: Anasyomosis History of the Bilioenteric Anastomosis.

Access and staging The first report by Molnar and Stockum 9 described a three phase approach to percutaneous dilation of choledochoenterostomy strictures. Biliary tract, Constriction, pathologic, Radiology, interventional, Stents.

A history of the bilioenteric anastomosis. After 6 months of stenting, repeat cholangiogram and stent retrieval can be performed. Most of the recent series conducting balloon dilations are able to effectively treat patients using moderate sedation with intravenous midazolam and fentanyl as for most interventional procedures.

Ahrendt, MD ; Henry A. Indeed, cutting balloons are often used at our own institution with good result Fig. At our institution, daily flushing of the catheter with 10 mL of normal saline bilioeterica used to ensure continued catheter patency.

Percutaneous dilation remains a safe and effective approach to benign biliary strictures, especially in post-surgical strictures at the bilioenteric anastomosis. Percutaneous treatment of benign bile duct strictures. No cholangitis, jaundice, and liver function test abnormalities were present in the postoperative. The medical charts of patients with biliary complications after OLT during a year periodwho failed to respond to nonsurgical treatment and were surgically treated, were reviewed.

Dissolvable stents made from polydioxanone Fig. An 18 F silicone biliary catheter with 6. Current strategies and future directions. The stent covering limits potential mucosal ingrowth and hyperplasia, factors which lead to occlusion and difficult retrieval in uncovered metallic stents. Our website uses cookies to enhance your experience. Percutaneous balloon dilatation and long-term drainage as treatment of anastomotic and nonanastomotic benign biliary strictures. Balloon dilatation of benign biliary strictures.

C A percutaneous wire has been advanced into the afferent jejunal limb and grasped by the endoscope. Illustration of three phase balloon dilation technique originally described by Molnar and Stockum Radiology. However the use of large bore stent catheters have shown better success overall than small bore catheters.

The current review aims to discuss various treatment protocols and their relative efficacy, as well as touch on emerging techniques. The most common interval for exchange and repeat cholangiography is 3 months, used in the majority of the most recent series. Only one patient died of causes not related to bile duct reconstruction during follow-up. Practice guidelines for adult antibiotic prophylaxis during vascular and interventional radiology procedures.

Purchase access Subscribe to the journal. At our institution the balloon is expanded to its rated pressure in a gradual fashion, with use of a larger diameter balloon or possibly cutting balloon should the current balloon prove insufficient to dilate the stricture.

We have found success at our institution using a rendezvous procedure for retrieval, where percutaneous access is maintained with a small caliber 8 F external biliary drain after initial stent placement. The medication is prescribed at mg by mouth twice daily, indefinitely. Terminology can vary, though for the purposes of this review, each case in which balloon dilation is performed is referred to as a dilation procedure, of which several may occur in a single dilation session.

Proponents of stenting with large caliber 16—18 F catheters argue that the insertion of the large caliber catheter is more important to treatment than balloon dilation. Lastly, withdrawing the cutting balloon catheter through the sheath can result in splaying of the tip of the sheath.

There is wide variation in the duration of balloon inflation during a given dilation procedure, ranging from 10 seconds to 12 hours. This catheter is then capped and the patient monitored over a time course of a few weeks to a few months. Gastrointestinal Intervention ; 6 1: Molnar, W, and Stockum, AE There is no formal protocol for maintenance of the stenting catheter by the patient between dilation sessions.
