If jaundice and obstruction before surgery are left untreated, then they can cause side effects such as cholangitis, delayed tumor treatment, decreased quality of life, and increased mortality. Surgery is the main treatment for HCCA. Therefore, this study was performed to compare the efficacy and complications of percutaneous transhepatic biliary drainage (PTBD) and endoscopic biliary drainage (EBD).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This cohort study was conducted on 20 patients with biliary obstruction who had been selected by simple random sampling and divided into two groups of EBD and PTBD. Three weeks after surgery, patients were compared in terms of bilirubin levels and postoperative complications. Data were analyzed by descriptive statistics (table, mean, and standard deviation) and inferential statistics (independent t-test, Chi-square test, and Fisher\u2019s test).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Independent\n                      <jats:italic toggle=\"yes\">t<\/jats:italic>\n                      -test did not show a significant difference between the two groups in terms of bilirubin level (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.77). However, despite a decrease in bilirubin level in both groups, independent t-test showed that this difference was not significant (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.08). Fisher\u2019s exact test showed a significant difference between the two groups in terms of postoperative complications (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.02).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Using both drainage methods before surgery reduced bilirubin levels in patients, but EBD method had fewer side effects than PTBD method.
