The study aimed to investigate the effect of biliary obstruction level on the technical success and complication rates of transhepatic percutaneous biliary drainage (TPBD). Patients who underwent TPBD due to malignant biliary obstruction were reviewed retrospectively. The study sample was separated into two groups according to the level of biliary obstruction. Patients with obstruction in the proximal cystic duct formed Group 1, and those in the distal of the cystic duct formed Group 2. The level of obstruction was determined based on magnetic resonance cholangiopancreatography (MRCP), computed tomography (CT) examinations, and intraoperative fluoroscopy images. Passing the biliary obstruction and providing percutaneous internal-external TPBD was determined as technical success. The effects of tumor location on technical success were investigated. In addition, patient demographic data and complication, morbidity, and mortality rates were compared between the two groups. The study included 56 patients, comprising 32 males and 24 females, with a mean age of 58.5 years, as 32.1% (n=18) in Group 1 and 67.9% (n=38) in Group 2. The technical success rate was 94.4% in Group 1 and 100% in Group 2. In Group 1, external drainage only was performed in 1 patient (5.6%) because the obstruction could not be passed despite all manipulations. There was no significant difference in technical success rates between the groups (p>0.05). No major complication was determined in either group. During the procedure, there were minor complications in 3 patients (16.6%) in Group 1 and 3 patients (8.5%) in Group 2. Complication rates were similar in both groups (p>0.05). There was no procedure-related morbidity and mortality. In conclusion, the localization of the biliary obstruction did not affect the technical success and complication rates of PTBD.
