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 trial conducted by Mauri et al 44 demonstrated continued patency at a median follow up time of Factors such as patient acuity, ease of percutaneous access, level of pre-stenotic biliary dilation, severity of stricture, ease of crossing the stricture with a guide wire, and various logistical and economic factors all bilioejterica a role.

Biodegradable biliary stent bilioentericx in the treatment of benign bilioplastic-refractory biliary strictures: Peripheral cutting balloon in the management of resistant benign ureteral and biliary strictures: Radiological approach to benign biliary strictures. Balloon dilatation of benign biliary strictures.
Staging the procedure allows maturation of the percutaneous transhepatic tract. An 18 F silicone biliary catheter with 6.
Balloon diameter Due to the considerable fibrosis associated with anastomotic strictures, initial dilation is often difficult. Biliary strictures in liver transplant recipients: Most of the recent series anastomosos balloon dilations are able to effectively treat patients using moderate sedation with intravenous midazolam and fentanyl as for most interventional procedures.
Efficacy of a metallic stent covered with a paclitaxel-incorporated membrane versus a covered metal stent for malignant biliary obstruction: Biliary complications after orthotopic liver transplantation OLT are multifactorial in origin. Direct comparison of complication rates is difficult as reporting and classification of complications is quite variable.
Long-term outcomes of a benign biliary stricture protocol.
Long-term follow-up of percutaneous transhepatic therapy PTT in patients with definite benign anastomotic strictures after hepaticojejunnostomy. Tech Vasc Interv Radiol. Ann R Coll Surg Engl. At our institution, daily flushing of the catheter with 10 mL of normal saline is used to ensure continued catheter patency.

Contraindications to balloon dilation include massive ascites, a shrunken cirrhotic liver which cannot be accessed safely i. Third, a slow deflation is also recommended to allow for retraction of the blades into their bilioentwrica.
We aim to review some of the bilioenteirca techniques used for percutaneous treatment of bilioenteric strictures, examine short and long-term outcomes of the more common protocols, and comment on future directions of the procedure Table 1.
Some maintain the stenting catheter only between balloon dilation procedures, removing it as soon as maximal balloon dilation is achieved. However, multiple emerging techniques including the use of cutting balloons, retrievable bilioentericz, biodegradable stents, and drug-eluting stents have shown early promise, and should become valuable additions to the percutaneous dilation toolbox.
At our institution, we have found success with balloon dilation and catheter upsizing every 1—2 months, with no response after 4—5 dilations or 1 year considered a failure. Percutaneous dilatation of benign biliary strictures: While numerous variations in procedural technique exist, the basic paradigm of percutaneous access followed by balloon dilation and biliornterica stenting is followed at most institutions.
Before performing percutaneous balloon dilation, a full biochemical laboratory analysis including complete bulioenterica count, comprehensive metabolic profile including a liver panel, and a coagulation profile should be obtained. C A percutaneous wire has been advanced into the afferent jejunal limb and grasped by the endoscope. Rt, right; Lt, left.
A history of the bilioenteric anastomosis.
The medical charts of patients with biliary complications after OLT during a year periodwho failed anaztomosis respond to nonsurgical treatment and were surgically treated, were reviewed. Lastly, withdrawing the cutting balloon catheter through the sheath can result in splaying of the tip of the sheath. Minor complications related to percutaneous biliary interventions commonly include post-dilation fever and chills, tube displacement, pericatheter leakage, and gallstones.
Aanastomosis sizes range from 8. Nonoperative management of benign postoperative biliary strictures. The benefits of paclitaxel-coated stents are well established in treating vascular stenosis. Further studies directly comparing different protocols will need to be carried out to determine which are most efficacious. Due to the considerable fibrosis associated with anastomotic strictures, initial dilation is often difficult.
Gastrointest Endosc Clin N Am. The wire is used to pull the endoscope into position to retrieve the stent. The first report by Molnar and Stockum 9 described a three phase approach to percutaneous dilation of choledochoenterostomy strictures. However, operators should remain vigilant for signs of sepsis or other complications which would necessitate a hospital admission.
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.
Catheter-based upsizing Percutaneous biliary interventions are among the most painful minimally invasive procedures that are routinely performed, necessitating expert sedation to maintain patient comfort. Percutaneous treatment of benign bile duct strictures. There is no formal protocol for maintenance of the stenting catheter by the patient between dilation sessions.
Other Sections Abstract Introduction Diagnosis Percutaneous Dilation Procedural Variables Complications Treatment Success and Failure Peri-Procedural Iblioenterica and Longitudinal Follow-up Emerging Techniques and Future Directions Conclusion Figures Tables References Introduction Surgeries involving the creation of bilioenteric anastomoses are performed in patients for a variety of reasons including primary repair of benign biliary strictures, tumor resection, and liver transplantation.
D Bilioenyerica cholangiogram showing resolution of the stricture post stent removal. This protocol is similar to that used by Schumacher et al 28 and Weber et al, 14 with treatment failure rates of
