Survival benefit of percutaneous transhepatic biliary drainage for malignant biliary tract obstruction—a prospective study comparing external and internal drainage techniques

Purpose To evaluate the clinical results of percutaneous transhepatic biliary drainage (PTBD) in patients with non-operable malignant biliary tract obstruction (MBTO) and the survival benefit of internal drainage. Methods Prospective data of consecutive patients of PTBD from May 2014 to August 2017...

Zusammenfassung:Purpose To evaluate the clinical results of percutaneous transhepatic biliary drainage (PTBD) in patients with non-operable malignant biliary tract obstruction (MBTO) and the survival benefit of internal drainage. Methods Prospective data of consecutive patients of PTBD from May 2014 to August 2017 was analyzed for 30-day, 90-day and 1-year mortality, and mean survival of patients undergoing external drainage (ED) and internal drainage (ID) using internal–external ring biliary catheterization or biliary stent were compared. Other important variables evaluated were drop in the total bilirubin (TBil) levels, improvement in pain and pruritus, procedure-related complications, and patient satisfaction. Results In 87 cases (54 male, 33 female) with mean age 37.3 y (22–70 y; 95% CI: 31.1 y–43.5 y), 10, 45 and 32 patients underwent stenting, external and internal-external catheterization, respectively (total 152 procedures [> 1 in 35.63%, n  = 31]). PTBD resulted in decrease in mean TBil by 8.2738 ± 0.912 mg/dL at 30 days ( P
