In clinical practice, perianal abscesses are primarily due to infection and inflammation of the anal glands, which then leads to the formation of red and swollen masses around the anus, causing pain and swelling near the anus. If not treated surgically in a timely manner, it can lead to necrotizing fasciitis or anal fistulas.

Minimally invasive surgery for perianal abscesses mainly aims to minimize damage to the anal sphincter during the procedure. Techniques such as loop drainage can be employed to preserve it, whereas traditional surgery generally involves larger incisions, but provides better drainage and has a lower recurrence rate post-operatively. However, leakage or moisture in the anal area can occur after traditional surgery.

For minimally invasive surgery for perianal abscesses, there is a relatively higher recurrence rate since the drainage may not be as effective. However, the integrity of the anus post-surgery is better preserved and incidents of leakage are less frequent. The choice of surgical method should still be based on the severity of the perianal abscess.
