The cost of surgery for a perianal abscess is not high, between $600 and $1,000, but the overall cost of treatment adds up to about $5,000 to $6,000. Because abscesses are inflammatory and infectious diseases, antibiotics need to be administered for symptomatic treatment to kill bacteria inside the wound before and after the surgery. Routine tests such as routine blood work, biochemistry, coagulation, electrocardiogram and possibly ultrasound diagnosis if the abscess is large are also needed before the surgery. During surgery, depending on the situation, if the abscess is superficial and small, it can be cut under local anesthesia, if the abscess is large, continuous epidural anesthesia is needed, and some patients may need general anesthesia, which may cost significantly more. The wound also needs to be changed after surgery and antibiotic treatment needs to be continued. Of course, there is a cost for changing the medication, and it is recommended that the medication be changed once a day so as to effectively promote wound healing.
