Anorectal melanoma: a rare aggressive type of melanoma (original) (raw)

ANZ Journal of Surgery, 2017

Abstract

We thank Bisset et al. for their comments on our previous study. Diabetes is indeed a risk factor for development of perianal abscess. In our study, we reported that diabetic patients have a significantly higher chance of having bacteriological studies done with odds ratios 2.22; 95% confidence interval 1.01–4.87. The observation of patients with bacteriological studies done with higher recurrence could indeed be confounded by diabetes. There is unfortunately insufficient data to do a subcohort analysis in this aspect. Amongst the patients whom are diabetic, we do not have data to compare those with good and poor glycaemic control. Interestingly, we did not encounter any cases of antibiotic resistance in our study cohort but it could be related to the nature of the study and the variable duration of follow-up. Finally, we included only patient with the index case of perianal abscess in order not to confound the analysis as reported in our methodology. References
