Fissura ani
A fissura ani will primarily be treated conservatively. If this doesn't work out, an operation can be done. In the presented case a partial cleavage of the internal sfincter is performed. In this way a lowering of the fissure-related elevated sfincterpressure can be achieved. Then healing of the fissure will follow. Because the cleavage is partial, incontinence will not follow.

In 1 the fissure can be seen, in 2 the sentinel pile that is often present at the beginning of the fissure, is removed with the electrical knife. After this the skin is opened at the right side and the sfincter is located and partially cut with scissors (3,4,5). The result is clearly visible and palpable to the finger (6). The remaining wound is not closed and will heal within a couple of weeks.
