Aspiration Treatment of Perianal Abscess

The aspiration drainage will be with a large caliber needle (MEDIPLAST® 13 G, 2,5 x 110 mm) and a syringe of 20 ml. The cavity must be emptied for pus and irrigated by repeated injection and aspiration of saline until clear fluid is obtained.

Incision drainage will be undertaken as standardized de-roofing of the abscess and debridement. Wound packing and dressing will not be used, just sitz bath or ordinary hygiene until wound healing.

Postoperative broad spectrum oral antibiotics covering both aerobes and anaerobes bacteria will be given for seven days of Clindamycin 300 mg tablets x 3 a day
