Minimally invasive perianal abscess is a minimally invasive procedure to treat a perianal abscess. Minimally invasive perianal abscesses typically require a pike-shaped incision of the abscess using a scalpel centered on the abscess. The interior of the abscess is explored and localized necrotic tissue is removed, along with the use of hydrogen peroxide solution to irrigate the abscess cavity, actively searching for internal openings and treating the perianal abscess completely. Minimally invasive perianal abscess has the advantages of small surgical incision, faster postoperative recovery as well as less harm to the patient, but may not be able to completely find the internal opening due to the small incision, and there is a situation where the pus cavity is left behind, which is prone to complications such as anal fistula. Although minimally invasive perianal abscess is less damaging to the human body, there may be incomplete treatment, and patients should choose the appropriate surgical method under the guidance of the doctor.
