Is it okay to wide the wound of anal fistulotomy when hosing water when cleaning? Just to make sure it don't have dirty in it? & When fully healed?

Here are some... For average healthy persons, hosing public tap water - not stagnating dirty water from rivers or ponds - to cleansing the wide open wound 2-3 days after anal fistulotomy should be okay as long as becoming less and less ache. Of course, keep regular postoperative F/U with the surgeon; besides, ask her/ him as needed. But, should avoid constipation.
