Percutaneous Ultrasound Guided Celiac Plexus Approach: Results in a Pig Cadaveric Model
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThis is a very interesting study and a good continuation of a previous publication by the same authors referenced in this work. I think it would be very nice to expand this research with clinical studies and to evaluate its analgesic response. However, until then, the authors need to be cautious when discussing the clinical application of this CP block, since it was not the aim of this paper. The authors should focus on the anatomy, the technique applied, macroscopical evaluation of the injection and the histological aspects, and relate the results obtained with the results of other studies in the swine or other species including humans. More specific comments on the pdf attached/ below.

Reviewer 2 Report
Comments and Suggestions for Authors
The manuscript is well structured, clear and well written. I have the following corrections/suggestions:
Line 16: Delete “and” … for block or neurolysis.
Line 65: “…transmission of pain controlled…” Delete controlled or rephrase this sentence.
Line 69: I suggest rewrite this sentence starting a new phrase as “Furthermore, validated tools….”.
Line 76. Replace “setting” for medicine.
Line 77. “clinical trials”.
Line 82. “in clinical setting in veterinary subjects” can be replaced by just one word: “animals”.
Line 93. The letter “p” of Pigs should be written in capital.
Line 95. The route of administration should be stated. Were pigs under general anaesthesia?
Line 131. I do not understand the meaning of “at least from 1 to 3 block per animals”
Line137. The word development could be deleted
Line 140. What do you mean by pressure? How was this pressure produced?
Line 165. Animals were positioned…
Line 174. Replace “window” for image and “cadaver” for cadavers.
Lines 226-231. This paragraph may not be relevant for your study. Perhaps it could be deleted.
Line 243. “have been reported” can be deleted.
Line 261/279. in alive subjects.
Line 318. “or?? C-shaped” Please revise this words.
Line 320. You should mention the species were a range of 0.5 to 4.5 cm was described. I assume it was not in pigs.
Line 325. You should define “IFs”
Line 395. I do not understand in the context of your work the meaning of “good sensitivity”.
