peripancreatic fluid collection with an external drainage-based approach

Reviewer's report:
Congratulations to the authors for the study
This is retrospective series of cases during an 8-year period of 14 patients with EUS guided
management of post-surgical peripancreatic liquid collections with external drainage.
The results found are interesting although some other study limitations should be added and
perhaps added to the discussion.
All 14 patients had undergone early drainage. In some cases, patients may not present any
symptoms or may only display mild symptoms. In this scenario, the collections could be
reabsorbed and thus intervention could be avoided.
Why is a nasobiliary drain preferred when the collection is liquid? In collections with solid
components, this method is used to allow wash serum to flow through the drain and prevent
obstruction. However, in this context it seems that it has not been the indication. On the other
hand, nasobiliary catheters are very uncomfortable for patients. For example, in pseudocyst
drainage, internal double pigtail stents have shown effective results and do not have high
migration rates.
