Manuscripts should be directly sent to Revista Chilena de Cirugía, Román Díaz 205 of 401, Providencia, Telephone-Fax 56 (2) 2351741, Santiago, Chile. They can also be sent by electronic mail using files not bigger than 1 megabyte to editor@cirujanosdechile.cl. Text and figures must be sent separately.

Form and preparation of manuscripts

 The manuscripts should be prepared according to the following instructions, considering some particular features of the journal and some characteristics determined in the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals”, established by the International Committee of Medical Journal Editors.

1. The manuscript must be written in letter size paper, double spaced and leaving 3 cm margins. All pages must be numbered in the upper right angle, starting by the title page. Two hard copies of the manuscript must be submitted along with a Microsoft Word for Windows, exact electronic copy of all the text, including references, tables and figures. Figures containing images (X rays or pathological slides) must be submitted as photographic copies in paper or electronic media. Photocopies will not be accepted. A computational word count must be depicted in the title page. This word count must exclude the title page, abstract, acknowledgments, tables, figures and references. The maximum number of words allowed is 2500 for Scientific manuscripts, 3000 for review articles, 1500 for case reports and 1000 for letters to the editor. For images and surgery, up to 200 words of text with up to four images are allowed.

2. Scientific papers should be divided in the following sections: Abstract, Introduction, Material and Methods, Results and Discussion. Case reports must include a summary, the case report, brief discussion and references. Other types of manuscripts can have other formats, but all must include an abstract and  must be approved by the editors.

Revista Chilena de Cirugía supports the clinical trial registry policy of the World Health Organization and of the International Committee of Medical Journal Editors (ICMJE). It recognizes the importance of this initiative for open access registry and international dissemination of information about clinical trials. As a consequence, in the near future, articles on clinical trials will only be accepted for publication if they have a registry identification number in one of the Clinical Trial Registries that have been validated according to criteria established by WHO or  ICMJE. The identification number must be depicted at the end of the abstract

(The concept is applied to experimental studies or those that include in their title the name “clinical trial or “prospective randomized study”)

Conflict of interest policy:

The authors must explicitly state in the title page if these is any conflict of interest between them, the contents of the article and any company related or not to health care.

Policy of informed consent:

Authors must state that an informed consent was obtained from participants in pertinent manuscripts. The basis of the informed consent is a conversation between the researcher and the participant. The essential issues of such interactions are depicted in a document that must be signed by the researcher to confirm that the participant was fully informed and by the participant to confirm that he or she consents to participate in the study.

When research was conducted in human beings, a statement indicating the ethical guidelines contained in the Helsinki declaration were respected and that the study was reviewed and approved by the ethics committee of the institution, where the study was conducted. If required by the editors, the authors should provide a copy of the document approving the study. Medications and chemical compounds employed in the study must be identified with their generic name, doses and routes of administration. Always disclose the number of participants or observations.

Manuscripts based on experiments done in animals must be approved by the ethics committee of the institution, must have a clear justification and will only be accepted if they have clear cut objectives. These issues must be explicitly indicated in the manuscript.

3. The order of each manuscript should be.

3.1 Title page, containing:

1) The title of the manuscript with its English translation, that must be concise but informative about the subject of the article.

2) Name of the authors identified by their given name, last name and initial of the second last name.

3) Institutions where the authors work and where the study was carried out.

4) Name and address of the corresponding author, including a mailing address and electronic mail.

5) Financing source, indicating the research Grants involved and institutions or companies that provided equipment, drugs or other type of support. All financial support and the possible influence of the financing source on the study must be disclosed.

6) Date of submission. The word count, as explained previously, must be added as a foot note. Each new section must start in a new page.

3.2 Abstract: The second page must contain an abstract of no more than 250 words, including a background, aims, material and methods, results and conclusions. Use only standard abbreviations. The complete phrase or sentence must precede the use of an abbreviation used for the first time. The authors can provide their own English translation of the abstract and title. The journal will perform the translation when the authors cannot do it. The Editors can modify the abstract provided by the authors. The authors can propose 5 key words, which ideally should be chosen from the Medical Subject Headings of the National Library of Medicine.

3.3 Introduction: Summarize and provide a clear aim of your work. When pertinent, inform about the hypothesis that you are trying to prove. Do not perform an extensive review of the subject and only cite the references that are relevant to your study.

3.4 Material and methods: Describe the selection of study subjects: patients, experimental animals, organs, tissues or cells and their respective controls. Identify the employed methods, instrumentation and procedures, precisely enough to allow other authors to reproduce your results. If frequently used methods were employed (including statistical methods), these should only me mentioned, providing the appropriate reference. When the methods have been published previously, but are not well known, provide a brief description and the reference. If the methods are new or have been modified, give a full description of them, describe the rationale behind their use and inform about their limitations. When experiments involving human beings were carried out, explain if all the ethical norms were followed, according to the Declaration of Helsinski (updated in 2000) and if the study was analyzed and approved by the ethics committee of the institution where the study was carried out. When required by the editors, the ethics committee approval document must be provided by the authors. Identify medications with their chemical names and indicate doses and mode of administration. Identify patients with correlative numbers, but do not use their initials or medical record number. Always report the number of patients or observations, statistical methods and the level of significance used to assess results.

3.5 Results: Report results using a logical and concordant sequence in the text, tables and figures. Data can be shown in tables or figures but not in both. In the text, outline the important observations and do not repeat the information provided in tables or figures. Do not mix the results with the discussion.

3.6 Discussion: Should be a discussion of the results obtained in the reported work and not a general review of the subject of study. Discuss only the new findings that your work provides and the conclusions that you obtained from your data. Do not repeat data presented in the results section. Discuss the concordances and discrepancies observed when comparing your results with those of other authors, identified with their respective references. Connect your conclusions with the aims of the study, mentioned in the introduction. Do not draw conclusions from results that you did not obtain or from other unfinished studies. Propose new hypotheses when advisable, but identify them as such. When appropriate, propose your recommendations.

3.7 Acknowledgements: Acknowledge only those individuals or institutions that made significant contributions to your work.

3.8 References: Limit the number of references to 40. Number the references consecutively as they appear for the first time in the text. Identify them with Arabic numerals at the end of the sentence that alludes them. The references cited only in tables or legends of figures, should be numbered in the sequence that corresponds to the first time that such tables or figures are cited in the text. Accepted but not already published manuscripts can be cited, adding the term “in press”.

The format for references should be as follows:

a) For articles in journals: Last name and first names initials of authors. Give the names of all authors when they are six or less; if they are seven or more, give the names of the first six, adding “et al”. Separate the names of authors with comas. Write the complete name of the article in its original language. The name of the journal should be written used the official abbreviations of the National Library of Medicine followed by year of publication; volume: initial-final page (example: 2006;34:234-6).

b) For book chapters, follow this example: 18. Croxatto H. Prostaglandinas. Funciones endocrinas del riñón. En: Pumarino H, ed. Endocrinología y Metabolismo. Santiago: Editorial Andrés Bello, 1984; 823-840.

c) For electronic articles: Cite authors, article title, and journal name as the paper publication, indicating the electronic site where the reference was obtained and the date of access. As example: Rev Méd Chile 2003; 131: 473-482. Available in: www.scielo.cl (Acceded on July 14, 2003). For other types of publications, follow the “Uniform Requirements for Articles Submitted to Biomedical Journals”. The authors are responsible for the exactitude of references.

3.9 Tables: Each table must be typed in a new page, separating cells with double spaces (1.5 lines). Number tables in consecutive order and give them a self-explaining title, with a brief description. Each column must have a short heading. Only separate with horizontal lines the column headings and the general titles. Columns must be separated by spaces and not by vertical lines. Explain each nonstandard abbreviation in a foot note. Cite the table in the consecutive order that it is mentioned in the text.

3.10 Figures: Denominate as figure any illustration that is not a table, such as X rays, graphics, electrocardiograms, etc.

igitalized figures should be saved in medium or high resolution in JPEG, TIFF, EPS, BMP or PICT formats, to allow their revision using the usual graphical software.  Letters, numbers and symbols should be sharp and should still be readable when the figure is reduced for publication. The size and contrast of symbols, arrows or letters employed in photographic reproduction of microscopic preparations, should be enough to distinguish them from the background. Cite each figure in the text in consecutive order. If a figure reproduces already published material, indicate its origin and obtain a written permission from the original author and editor to reproduce it. If photographs of patients are included, their face must be covered to avoid their identification.

3.11 Figure legends: Type figure titles and legends in a separate page. Identify and explain all symbols, arrows, numbers or letters used in the illustrations.

3.12: Units of measure: Use metrical units of measure.

3.13: Galley proof corrections: The galley proofs are sent to the author for their final revision.  Only formal corrections, but not of the meaning or content of the manuscript, will be accepted in this instance.
