Abces perianal
An abcess arises when an infection in the tissues gets out of hand and the natural defense of the body is not able to fight the penetrated bacteria sufficiently. Once an abcess has formed antibiotics will no longer help and surgical intervention is mandatory:
'ibi pus, ibi evacua' - or: where there's pus it must be removed

In this case there is an abces near the anus. The cause is an inflammation in the glands at the transition of the anal skin to the mucosal lining of the gut. The inflammation can lead to an abces that can spontaneously rupture into the rectum or to the tissue away from the anus. It may be a deep abces or a more superficial one. Here we have a deep abces. In 1 and 2 a swelling of the buttock is caused by the inflammation. The deep abces is localised by puncture (3). Then an ellipse of skin is removed to make sure that the wound stays open after surgery. With a finger the deeply located abces is reached after which the pus is freed (4). A drain is left behind, also to ensure the drainage of the pus.
Then a bandage is applied. After the operation the wound has to be cleaned / rinsed twice or three times daily. After some days the drain may be removed and then the wound will heal in about three weeks.
