G1 of the hilar bile duct: a case report

Reviewer's report:
Daer Sir, the article is well written, and scientfically correct. I have only 
few
comments for the Authors.
How the patient's follow-up was conducted, with what laboratory and
radiological tests. also what was the timing and how long it will continue.
Why was a percutaneous transhepatic biliary drainage performed, and not an
endoscopic retrograde cholangiopancreatography (ERCP) with stent positioning?
Best regards
