Perianal abscesses generally have two treatment options. Initially, if the abscess is not very large and the swelling and pain are not particularly severe, conservative treatment with antibiotics can be used temporarily. If conservative treatment is ineffective and the swelling worsens, surgical treatment may be necessary. In cases of severe abscesses, incision and drainage can be considered first, followed by antibiotic treatment. Surgical definitive treatment can then be performed 3-5 days later.

Differences between minimally invasive surgery and traditional surgery for perianal abscess

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.

Can an anal abscess without pus be treated without surgery?

Perianal abscesses require surgical treatment even if there is no pus present, as early-stage perianal abscesses are primarily characterized by pain and noticeable lumps near the anus, with the lumps typically being hard. This condition is mainly considered to be an infection and inflammation of the anal glands, which then infects the surrounding tissue, leading to the development of lumps. Surgical treatment should be undertaken as soon as possible even in the absence of pus, because as the infection worsens over time, it may lead to the formation of pus. Early treatment can be advantageous as the infected area is not very extensive, thus resulting in a smaller surgical wound. For early-stage perianal abscesses, a one-time radical surgery may be chosen to remove the internal opening and the infected tissue thoroughly, followed by postoperative care using medicated substances such as erythromycin ointment gauze, anal washes, or mupirocin ointment to promote healing of the surgical wound.

Can you eat fish with a perianal abscess?

Patients with perianal abscesses should avoid eating seafood or consuming excessive amounts of seafood products. Because fish and seafood are considered to provoke symptoms in traditional beliefs, their overconsumption can lead to congestion and swelling of the local mucosa. Along with an acute infection of a perianal abscess, food may exacerbate the infection. Therefore, the diet of patients with a perianal abscess should primarily be bland. Additionally, once a perianal abscess is detected, it is necessary to perform an incision and drainage procedure for the abscess promptly, as well as a one-time debridement and radical surgery to prevent the further expansion of the abscess cavity or recurrent infection leading to the formation of anal fistulas.

Precautions for Perianal Abscess

The precautions for perianal abscess mainly include those during an acute episode and post-surgical measures. If it is clearly an acute onset of a perianal abscess, it is important to seek treatment promptly. Treatment methods, besides incision and drainage, further include debridement to achieve a complete cure through surgery. Generally, simple incision and drainage only alleviate temporary pain symptoms. If not followed by definitive surgery, there is a high likelihood of developing anal fistulas, necessitating a second surgery. Post-surgical precautions for a perianal abscess primarily involve maintaining cleanliness of the local wound, changing dressings, and ensuring that the drainage from the wound remains unobstructed to prevent false healing.
