Description
Summary:	Purpose To describe a novel technique of percutaneous transhepatic (PTH) placement of a plastic biliary stent (PBS), report the feasibility and safety of the technique, and present the preliminary results of a pilot study that included 32 patients with symptomatic obstructive jaundice (SOJ) treated with the technique. Materials and methods This was a prospective, single-arm, single-center, pilot study of a cohort of patients with the diagnosis of benign or malignant obstructive jaundice that underwent PTH placement of a PBS to relieve the obstruction. Results Thirty-two patients were included, 16 men and 16 women (age range, 35–88 years). There were 26 malignant and six benign lesions. Cholangiocarcinoma was the most common tumor ( n =13, 40.6%), followed by pancreatic adenocarcinoma ( n =6, 18.75%) and metastasis ( n =5, 15.6%). A total of 35 PBSs were placed in 32 procedures. The bile duct was accessed and drained to the right side in 18 cases, to the left side in 14 cases, and bilaterally in three cases. Technical success was achieved in 100% and clinical success in 93.7% of cases. Using a modified Bismuth-Cortelle classification system, type I was observed in nine patients, type II in nine patients, type III in six patients, and type IV in eight patients. The mean follow-up was 426.1 days for the total sample, and 349.4 days for patients with malignancy. Two complications were observed: transient hemobilia and cholangitis. Conclusion PTH placement of a PBS in patients with SOJ is feasible, safe, and effective.
