Title:Extracorporeal shock wave lithotripsy treatment of pancreatic stones
complicated with advanced stage autoimmune pancreatitis
Version:3Date:10 December 2014
Reviewer: Jimin Han
Reviewer's report:
- Major Compulsory Revisions
1. Appropriate citation is needed for second line of third paragraph in the
Introduction section.
2. Design of the study is not described in the Methods section (e.g., prospective,
retrospective, retrospective analysis of prospectively collected date).
3. Definitions for technical success of ESWL, pancreatic function (used in Table
2) and complications related to ESWL should be given in the Methods section.
4. According to previous studies, smoking status (not smoking or cessation) is
related to efficacy of ESWL and pain relief after ESWL for chronic pancreatitis
(Clin Gastroenterol Hepatol 2004;2(12):1096 and Gastrointest Endos
2012;75(5):997). If possible, please describe the smoking status of the study
subjects. If not, please consider including this point in the Discussion section.
5. Figure 3-1 should be relabeled as Figure 3 and Figure 3-2 as Figure 4.
6. In Figures 3-1 and 3-2, please specify the staining method and number of
magnification used.
- Minor Essential Revisions
1. First sentence of the Conclusions must be a complete sentence, not a clause.
2. “Keywords” should be bold letters (e.g., Keywords).
3. First letters of the keywords should be capitalized.
4. Heading “Introduction” should be changed to “Background”.
5. First line of first paragraph in each heading should be without tab. For
example, the following is the style used in BMC Gastroenterology.
“Introduction
Autoimmune pancreatitis (AIP) has been recognized as a distinct type of”
However, first line of second paragraph uses a tab of two letters.
6. In the Methods section under Study subjections, “SIEMENS” should be
“Siemens”.
7. For consistency, subheadings in the Discussion section should be without
numbers (e.g., Is pancreatic calculus treatment of AIP different from that of the
ordinary CP?)
8. “Authors’ information” should be changed to “Author details”.
9. Acknowledgements should be put before Author details.
10. Please change all the references according to the style used in BMC
Gastroenterology. The correct style would be “Okazaki K, Uchida K, Koyabu M,
H Miyoshi H, Takaoka M: Recent advances in the concept and diagnosis of
autoimmune pancreatitis and IgG4-related disease. J Gastroenterol 2011, 46:
277-288.”
11. Use of abbreviations in the titles of Tables is not recommended (e.g., AIP,
CP) Abbreviations in the tables should be explained at the bottom of the tables
(e.g., M, male; F, female).
12. In Figure legends, “Fig. 1” should be “Figure 1” and so on.
- Discretionary Revisions
1. In eighth and tenth lines of first paragraph in the Discussion section, the term
“dilation” is more widely used and would be preferable over “expansion”.
