Title: Prognostic nomogram for acute pancreatitis after percutaneous biliary stent insertion in
patients with malignant obstruction
Version: 1 Date: 04 Aug 2022
Reviewer's report:
This is a manuscript developing and varidating the prognostic nomogram for acute pancreatitis
adter percutaneous transhepatic biliary  stent insertion in patients with malignant biliary
obstrustion.
Although this manuscript is likely to be well written, there are some issues to be concerned.
Major
Nowadays, endoscopic biliary drainage is the mainstay  for malignant biliary obstruction.
Nonethless, It is understantable that radiologists still play a role in this topic in some institutions,
regions, or countrires.
However, "BMC Gastroenterology" is the journal of gastroenterology, not of radiology. I
suppose that most readers of this journal  may be more interested in endoscopic drainage than
percutaneous drainage.
Therefore, the pros and cons of PTBS comparing  endoscopic dranaige had better to be discussed
in introduction or discussion section.
Minor
1. Line 51-52
Full spelling of PTBS is expressed as percutaneous biliary insertion. However, I guess that
percutaneous transhepatic biliary insertion is roght. Please confirm it.
2. Line 85-88
Can a 0.035-inch guidewire really pass through a 21-gauge needle?  I think the guidewire  is
too thick.
3. In results section
There should be a table regarding characteristics  of whole patients. Moreover, the  severity of
pancreactitis or period of hospitalization regarding pancreatitis should be contained in the table.
