Biliary-enteric anastomosis (BEA) is a common surgical procedure performed for the management of biliary obstruction or leakage that results. Postoperative bilioenteric anastomotic strictures are encountered in a significant number of patients after primary biliary repair, hepatopancreaticobiliary tumor. access to the bilioenteric anastomosis and thus to the hepatobiliary tree for non- operative management of chronic and recurrent biliary tract.

The most common interval for exchange and repeat cholangiography is 3 months, used in the majority of the most recent series.
Saad et al 36 conducted a trial involving 22 patients using a protocol featuring multiple sessions of cutting balloon dilation followed by conventional balloon dilation, separated by short-term small caliber catheter stenting. Purchase access Subscribe to JN Learning for one year. Illustration of three phase balloon dilation technique originally described by Molnar and Stockum Radiology. Long-term safety and efficacy of drug-eluting versus bare-metal stents in Sweden.
However, operators should remain vigilant for signs of sepsis or other complications which would necessitate a hospital admission. Sign in to download free article PDFs Sign in to access your subscriptions Sign in to your personal account.
A history of the bilioenteric anastomosis.
Lastly, withdrawing the cutting balloon catheter through the sheath can result in splaying of the tip of the sheath. Nonoperative management of benign postoperative biliary strictures. No cholangitis, jaundice, and liver function test abnormalities were present in the postoperative. Indeed, cutting balloons are often used at our own institution with good result Fig.
Percutaneous transhepatic balloon dilatation of benign bilioenteric strictures: After 6 months of stenting, repeat cholangiogram and stent retrieval can be performed. Subsequent dilations and catheter exchanges can usually be performed on an outpatient basis. 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.
Segments IV and V were partially removed after cutting the hilar plate, thus obtaining healthy ducts without ischemic or inflammatory reaction and allowing a wide hepatojejunostomy.

Some protocols use sequential stricture dilation with catheters, rather than balloon inflation, as the main mechanism of treatment. Aspirin should be held for 5 days if a new biliary tract is being created; Clopidigrel should be held for 5 days regardless. The current review aims to discuss various treatment protocols and their relative efficacy, as well as touch on emerging techniques.
Drug eluting biliary stents to decrease stent failure rates: Practice guidelines for adult antibiotic prophylaxis during vascular and interventional radiology procedures. This is supported by the finding that anastomotic patency is better when surgically-placed stents are in place for longer than 1 year.
A history of the bilioenteric anastomosis.
Long-term follow-up of percutaneous transhepatic biliary drainage PTBD in patients with benign bilioenterostomy stricture. Long-term outcome of percutaneous transhepatic therapy for benign bilioenteric anastomotic strictures.
Biliary obstruction due to fragmentation of the stent is a potential complication resulting in transient cholangitis, though is likely less pronounced in the context of a bilioenteric anastomotic stricture. The embedded blades create small controlled incisions which score the stricture, allowing for a more effective subsequent dilation by the balloon via crack propagation.
Long term maintenance of an indwelling biliary stent catheter requires routine exchanges to ensure continued patency of the catheter, evaluate the stricture and perform repeat dilation when necessary.
Bilienterica is no formal protocol for maintenance of the stenting catheter by the patient between dilation sessions. Percutaneous transhepatic treatment of postoperative bile bilioenteruca Coronal magnetic resonance cholangiopancreatography MRCP -echoplanar fast spin echo sequence showing focal filling defect at the hepaticojejunostomy in a year-old female with jaundice 3 months after robotic pancreaticoduodenectomy.
The benefits of paclitaxel-coated stents are well established in treating vascular stenosis. It is hypothesized that the longer-term catheter dilation allows healing of the stricture around the catheter, determining the overall end result.
A single treatment consists of one or multiple dilation sessions separated by intervals ansatomosis catheter stenting. At our institution, general anesthesia is routinely used for biliary dilation and stenting procedures. Percutaneous treatment of benign bile duct strictures.
A History of the Bilioenteric Anastomosis
While the overall paradigm of percutaneous access, balloon dilation, and catheter anastomodis remains consistent, institutional protocols differ biloenterica several technical variables including balloon sizes, inflation techniques, catheter sizing, and overall time course of treatment, amongst others.
The catheter was subsequently removed. The trial conducted by Mauri et al 44 demonstrated continued patency at a median follow up time of Second, a slow inflation is recommended so as not to induce undue trauma to the duct.
Anastomotic strictures are generally thought to form due to fibrosis with resultant retraction, as opposed to non-anastomotic benign biliary strictures which often occur due to iatrogenic causes most commonly during cholecystectomychronic biliary inflammation, or ischemia during hepatic transplant. A Cholangiogram demonstrates a biliary stricture at the hepaticojejunostomy recalcitrant to balloon dilation.
Differences in protocol are largely anecdotal, with no current evidence-based research demonstrating the superiority of any particular technique. Some maintain the stenting catheter only between balloon dilation procedures, removing it as soon as maximal balloon dilation is achieved.
Long-term follow-up of percutaneous transhepatic therapy PTT in patients with definite benign anastomotic strictures after hepaticojejunnostomy.
Once stenting has been maintained for longer than 1 year without desired clinical result, treatment is unlikely to be successful.
However, treatment subjects in that study were exclusively post-transplant, confounding a direct comparison. Mean follow-up was 24 months.
Balloon inflation duration There is wide variation in the duration of balloon inflation during a given dilation procedure, ranging from 10 seconds to 12 hours.
At our institution, daily flushing of the catheter with 10 mL of normal saline is used to ensure continued catheter anaastomosis. However some operators advocate more frequent exchanges, with some intervals on the order of a few days.
