Title: Fishing line assisted endoscopic placement of multiple plastic biliary stents for
unresectable malignant hilar biliary obstruction: a retrospective study
Version: 0 Date: 14 Aug 2021
Reviewer's report:
The study entitled “Fishing line assisted endoscopic placement of multiple plastic biliary stents
for unresectable malignant hilar biliary obstruction: a retrospective study” demonstrated an
interesting technique to prevent upward stent migration during the deployment of the following
stent(s) when performing multiple plastic stenting. Although this is a smart way to prevent it,
the number of cases and the design of this study could not convince to the conclusion that
recommended this as the preferred technique. I afraid this may not be the flavor for BMC
Gastroenterology. I would recommend this manuscript to submit as a video series of special
technique in the endoscopy related journal.
Minor points:
1. Unclear introduction, stent migration, upward or downward? How this developed? And the
real incidence? The introduction does not demonstrate the problem that can lead to the remedy
that the authors planned to do.
2. Methods: should explained more details of the technique.
3. Outcome: technical success may not be a good surrogate to compare as the stent insertion is
almost always successful no matter what technique is employed.
4. Time: the time spent for assemble the thread should be counted and I wonder this still makes
the FLA technique still faster or not.
