Title: Biliary obstruction and pancreatitis after duodenal stent placement in the descending
duodenum: a retrospective study
Version: 2 Date: 18 Apr 2022
Reviewer's report:
The authors describe risk factors when stent placement in the descending duodenum causes acute
cholangitis and pancreatitis.
It is very important to assess the risk of treatment when performing endoscopic treatment.
But the following points require further elaboration.
Major points
What is the significance of performing a risk assessment that combines cholangitis and
pancreatitis?
In this report as well, the treatments for cholangitis and pancreatitis are different, and I would
like to know the risks of each.
Minor points
P3, L56: Reference [12] is about stent placement for distal bile duct stenosis and dose not
describe duodenal stents, please delete it.
P5, L86-89: The explanations in Figures 1a and 1b are different from the actual figures. Please
write the appropriate text.
P6, L101-103: Did the author measure the diameter with CT images? Please describe so that
you can see which modality you used.
P8, L150-151: Please consider in the discussion that there is a significant difference in the
duration of onset of pancreatitis and cholangitis.
Fig 1a: Please insert a mark on the figure to identify the location of the stenosis.
Table 2: If you have made a statistical evaluation, please describe the result.
