Reviewer’ s report
Title: Validation of the moroccan arabic version of the low anterior resection syndrome score
Version: 0Date: 22 Jul 2020
Reviewer's report:This paper will benefit Arabic speaking patients after resection and anastomosis of the rectum. In
this light, I believe it is important to publish this and comparable studies.
I have some remarks:Introduction: The questionaire is translated to Moroccan Arabic. I have learned previously that
Arabic may be written comparably in the different Arabic speaking countries, but the spokenversion may differ considerably. Can it be used in other Arabic dialects? If not, the title shouldspecify the Moroccan limitation of this translation.
Methods: when unable to read, an interviewer solemnly read the questions and answers. The same
was done Please reflect on any bias this may have given. How many patients were not able toread. How many patients were interviewed by telephone.
Please reflect in general on any cultural tradition in Morocco that may embarrass the patient to
discuss faecal continence problems with their doctor or other health care provider (or family). Dothe authors believe this is present and did it influence the results? If LARS is in a taboo sphere inMorocco, it is especially important to have a validated Arabic questionaire available.
