placement of a covered self-expandable metal stent

Reviewer's report:
Dear sir,
With interest I read the case-report entitled, “Arterial bleeding during EUS-guided
pseudocyst drainage stopped by placement of a covered expandable metal
stent” by Saftoiu et al.
The case-report describes an EUS-guided pseudocystdrainage complicated by
an arterial bleeding which was managed by tamponade by means of a covered
metallic stent.
Albeit interesting and successfully managed (for which I congratulate the
authors), this kind of approach is not novel and has indeed already been widely
applied in parallel conditions during biliopancreatic interventions (reference 18-20
in this case report). Moreover, recently a case-series of 4 patients with similar
conditions were presented by Baron et al (GI Endoscopy November 2012) with a
larger and nicer iconography. The images and in particular the video is very
blurry and difficult to interpret despite the fact that I am an endosonographist.
The authors should try to improve the quality and type of images in order to
render this case report more attractive.
Additionally, the authors should be careful not to go along with unsubstantiated
prophetic statements when touching on the superiority of metallic stent for
drainage of PCFs (“advantage of larger diameter and possible decrease of
recurrence rate”). These premises are stated on case-series and remain to be
proven in RCTs.
Level of interest: An article of limited interest
Quality of written English: Needs some language corrections before being
published
Statistical review: No, the manuscript does not need to be seen by a
statistician.
