Title: The important role of whole-process Computed Tomography guidance for percutaneous
gastrostomy in esophageal cancer patients who are unsuitable for or have had unsuccessful
attempts with endoscopic and fluoroscopic gastrostomy

Reviewer's report:
PEER REVIEWER ASSESSMENTS:
OBJECTIVE - Full research articles: is there a clear objective that addresses a testable research
question(s) (brief or other article types: is there a clear objective)?
Yes - there is a clear objective
DESIGN - Is the current approach (including controls and analysis protocols) appropriate for
the objective?
Yes - the approach is appropriate
EXECUTION - Are the experiments and analyses performed with technical rigor to allow
confidence in the results?
Yes - experiments and analyses were performed appropriately
STATISTICS - Is the use of statistics in the manuscript appropriate?
Yes - appropriate statistical analyses have been used in the study
INTERPRETATION - Is the current interpretation/discussion of the results reasonable and not
overstated?
Yes - the author's interpretation is reasonable
OVERALL MANUSCRIPT POTENTIAL - Is the current version of this work technically
sound? If not, can revisions be made to make the work technically sound?
Probably - with minor revisions
PEER REVIEWER COMMENTS:
GENERAL COMMENTS: The overall impression is good. The authors belong to tertiary
care teaching hospitals looking after severely ill advanced cases of esophageal cancers with
complications of obstruction, fistula and cardiac comorbidities in which its common to find
contraindications and failed attempted at gold standard PEG placement or fluoroscopic feeding
tube placements. They have reported their nearly a decade experience from two hospitals
although retrospectively but has shown safety, effectiveness and feasibility of this important
alternative technique with low complication rate .The objective, study design, execution, and
interpretation seems reasonable and may need minor corrections.
ADDITIONAL REQUESTS/SUGGESTIONS:
The language of the presentation needs improvement and professional editing service or person
whose first language is English may be able to help.
Few minor suggestions are as follows:
Suggested title- The whole process computed tomography guided percutaneous gastrostomy-
an important role in patients unsuitable or attempted endoscopy and fluoroscopy in esophageal
cancer
Consent for publication: All of the 32 patients has signed in the informed consent form.
Keywords: Esophageal cancer; dysphagia; feeding tube placement; interventional radiological
procedure, refractory; percutaneous gastrostomy, whole process CT guided.
