When it comes to a second surgery for a perianal abscess, it is generally recommended to proceed directly with spinal anesthesia. Simple local anesthesia might be more painful for the patient, as spinal anesthesia does not cause pain sensations. If there is pain after the surgery, one can opt for oral painkillers or a combination of pain relief pump treatments. Alternatively, pain relief gel can be applied to the wound to alleviate pain before each dressing change. Therefore, after the onset of a perianal abscess, whether it is the first or second surgery, it is essential to operate as soon as possible, and to disinfect and change dressings postoperatively to prevent pseudo-healing or secondary recurrent infections. To relieve pain, painkillers can be chosen. Before or after each bowel movement, one may use clean water for local cleansing to soothe the sphincter and prevent fecal residue.

Can a perianal abscess be treated with hot compresses?

Hot compress therapy for perianal abscesses is typically chosen after surgery. Prior to surgery, due to the formation of a typical pus cavity in the perianal abscess and the encapsulation of pus fluid, it is an acute infectious foci. Using hot compress therapy can easily lead to further aggravation of the local infection or spread of the pus cavity, which may worsen the condition. Therefore, hot compresses are not recommended before surgery. After promptly conducting surgery on a perianal abscess, since the local wound contains infectious material, it is suitable to fumigate and apply hot compresses postoperatively to disinfect the local wound further, and to manage residual fecal matter to prevent infection. Additionally, changing dressings is necessary to promote the fresh growth of normal granulation tissue, thus leading to the proper healing of the wound rather than pseudohealing or infection.

How to drain pus when a perianal abscess bursts?

If an anal abscess ruptures, it then forms an anal fistula. Both the acute phase of an anal abscess and anal fistula require surgical treatment. If only the local pus is drained, it is generally recommended to open the abscess cavity for local debridement and disinfection, and to further excise the infection focus. During surgery, to protect the function of the local anal sphincter, a seton stitch procedure is also needed. Post-surgery, it is necessary to disinfect and change dressings for the local wound, and ensure normal growth of the granulation tissue to prevent the occurrence of false healing.

How to eliminate a perianal abscess mass?

Perianal abscess nodules are primarily caused by inflammatory infections that lead to local fibrosis, which then forms the nodules. For these nodules, it is recommended to employ a one-time radical cure surgery for perianal abscesses, mainly to remove the internal opening and the inflamed infected tissues. Since a perianal abscess can form a fistula after bursting on its own, failing to completely remove the infected tissue may lead to the development of anal fistulas later. Therefore, clinically, for perianal abscess nodules, it is advised to treat them with a one-time radical cure surgery for perianal abscesses. Post-surgery, medications such as anal washes and red oil ointment gauze strips are chosen for dressing changes. As for early-stage perianal abscess nodules, these are mainly inflammatory infections causing red and swollen lumps, which gradually turn into purulent and liquefied masses. Once suppuration occurs, they can be opened and drained, thereby causing the nodules to disappear. The nodules formed after incision and drainage are mainly considered to be from inflammatory spread to fibrotic tissue, and thus, surgical removal is required in these cases.

Can a perianal abscess heal by itself?

During the acute phase of a perianal abscess, there is significant local redness, swelling, heat, and pain around the anus. Generally, this condition is caused by an infection of the anal crypts, and the possibility of self-healing is very low, so the main treatment for a perianal abscess is surgery. The surgical approach usually involves incision and drainage of the perianal abscess, combined with a one-time curative surgery. If the abscess ruptures and forms an anal fistula, surgical treatment is also required. During the outbreak of a perianal abscess, due to the severe local pain, it is advisable to undergo surgery as soon as possible to prevent further spread of the abscess. Simple topical medications can only relieve the symptoms of local inflammatory infection and cannot achieve a cure.

Causes of perianal abscess formation in babies

In pediatric outpatient surgery, perianal abscesses are not uncommon, and many parents visit the hospital daily for this issue. They wait, register, and change dressings. Once the wound heals, it often recurs after a while, leading to repeated incisions and drainage, persisting for several months. Eventually, the doctors say a fistula has formed and surgery is required. What exactly causes such troublesome perianal abscesses? The cause of perianal abscesses is not completely clear, but many affected children have been found to have deeper anal crypts than normal, so it's speculated that it may be related to this abnormality. In children under two years old, perianal abscesses mostly occur in boys. Some studies suggest that testosterone levels are higher in boys aged 1-3 months, coinciding with a peak period for perianal abscess incidences, leading to speculation that it may be related to the child’s hormone levels. In children over two years old, there is less gender bias in the incidence of perianal abscesses, and some cases are secondary to Crohn’s disease.
