To the Editor,
We read with great interest the recent article by Khosla et al. . The authors concluded percutaneous transhepatic biliary drain placement (PTBD) may not achieve decreasing bilirubin in patients with a malignant obstruction. However, we would like to elaborate on this conclusion.
PTBD has been used widely in the treatment of obstructive jaundice and approved by Society of Interventional Radiology (SIR) [2, 3, 4, 5]. The safety and effectiveness of PTBD in the treatment of patients with malignant obstruction have been proved [2, 3, 4]. However, the authors concluded PTBD may not achieve decreasing bilirubin in patients with a malignant obstruction. This conclusion is inconsistent with previous studies. A prospective randomized clinical trial with a large sample size is needed to validate this hypothesis.
