Abstract
Percutaneous transhepatic biliary drainage (PTBD) has a crucial role in treatment of proximal biliary cancer (PBC). We assessed the incidence, risk factors, and impact of acute pancreatitis (AP) post-PTBD. Forty patients with PBC scheduled for PTBD from January 2005 to December 2015 were enrolled. Exclusion criteria were missing clinical data, PTBD performed in other institutions, and palliative PTBD. The 40 patients comprised 8 (20%) with gallbladder cancer, 6 (15%) with intrahepatic cholangiocarcinoma, and 26 (65%) with perihilar cholangiocarcinoma. A median of 1 PTBD procedure was performed per patient; 16 (40%) patients underwent PTBD more than once. PTBD was left-sided in 14 (35.0%) patients, right-sided in 21 (52.5%), and bilobar in 5(12.5%). Seventeen (42.5%) patients had one or more drainage-related complications. Five (12.5%) patients developed AP. A significantly higher percentage of patients with than without AP developed sepsis (60.0 vs. 11.4%, respectively) and did not undergo the planned liver resection [2 (40.0%) vs. 0 (0.0%), respectively]. Significantly more patients with than without AP underwent left-sided PTBD [10 (28.6%) vs. 4 (80.0%), respectively]. PTBD is frequently complicated by AP. AP plays a key role in the development of sepsis. Nearly half of patients with AP lose the opportunity for surgical treatment.
