Transhepatic Percutaneous Sustained Dilation with Multiple Catheters for the Management of Hepaticojejunostomy Benign...

Benign biliary strictures (BBS) befall in ∼7%-23% after hepaticojejunostomy and in 0.3%-0.6% after cholecystectomies. Their treatment options include surgical, endoscopic, and percutaneous management. The percutaneous approach is an excellent mini-invasive option including balloon dilation, biodegradable stents, and sustained dilation, a procedure born endoscopically. However, when the endoscopic approach fails or it is not available, it is possible to perform it percutaneously. To estimate the technical and clinical success of sustained percutaneous dilation with multiple catheters (SPDMC) in hepaticojejunostomy strictures and the percentage of complications and recurrence. : We conducted a retrospective study, from a prospective database from January 2010 to March 2019, of 17 patients with postoperative BBS who failed to percutaneous pneumatic balloon dilation and underwent SPDMC with a mean follow-up of 2 years. Seventeen patients between 28 and 71 years of age underwent SPMDC with technical success of 100%; the average number of catheters used was 5.59 (95% confidence interval [CI] 5.12-6.06) achieving a dilatation diameter of 16.15 mm (95% CI 14.71-17.60), and the therapeutic success rate was 71%, with recurrences of stricture and complications of 29% and 18%, respectively. The mean time with SPMDC was 7.06 months (95% CI 5.56-8.56). The median follow-up after dilation was 16 months, with an average of 27.75 months (95% CI 14.15-41.34). SPMDC is a feasible technique with a high technical success rate, therapeutic success rate, and low morbidity and mortality.
