Correction

After the publication of this work[1] it was brought to the authors attention that Figure five(Figure 1 here) contained a duplication error in the PDF format, where it featured a perianal fistula instead of a rectovestibular fistula in females. The correct figure is given below:

Figure 1
figure 1

Rectovestibular fistula in females.

We regret any inconvenience that this inaccuracy may have caused.
