Anal abscess tight skin tendon pain for a few days
If a perianal abscess undergoes a rubber band ligation surgery, the rubber band may fall off within a week to ten days. If the local rubber band is too loose or takes longer to fall off after surgery, the doctor can further tighten the local rubber band to promote its earlier detachment and ensure the function of the local sphincter around the anus. After tightening the rubber band, the local wound may experience significant pain and minor bleeding due to the pulling of the rubber band. The pain usually lasts about one to two days and will gradually subside as the local wound heals.
Thrombotic external hemorrhoids clinical characteristics
The clinical features of thrombosed external hemorrhoids primarily include acute episodes of localized swelling and pain in the anal area, with thrombosis forming in the local hemorrhoidal tissue. This condition is primarily due to dry stools and excessive straining during bowel movements, leading to congestion and edema in the local hemorrhoidal tissue and subsequent disruption of local blood circulation, resulting in thrombosis. After an attack, the anal hemorrhoidal tissue may display dark red or purplish clots, enclosed by the local skin and mucous membrane. Treatment options include the application of topical medications and hot compresses to promote absorption of the hemorrhoids, as well as local surgical excision. It is important to note that if rupture or bleeding occurs, considering the possibility of local thrombus rupture, it is essential to perform proper local cleaning and disinfection and to promptly proceed with surgical excision to prevent infection.
Can a perianal abscess heal by itself without rupturing?
Perianal abscesses that have not ruptured generally involve two scenarios. First, the application of topical or oral antibiotics may eliminate the local abscess, but some infection foci and swelling may persist, with a possibility of recurrence later. The second scenario occurs when the abscess does not rupture, but the pus chamber further expands, leading to an increase in the area of infection and thus worsening systemic infection symptoms. Once a perianal abscess is detected, it is necessary to treat it promptly. If an early-stage typical pus chamber has not formed, antibiotics can be used for symptomatic treatment to reduce local inflammation. If a clear pus chamber has formed and is accompanied by pus, it is advisable to promptly perform an incision and drainage of the abscess, followed by a definitive surgical debridement.
Which is more serious, perianal abscess or hemorrhoids?
Perianal abscesses and hemorrhoids are two different types of anorectal diseases. During the acute phase of a perianal abscess, the urgency of the condition is greater than that of hemorrhoids. If active surgical intervention and incisional drainage and debridement are not carried out for a perianal abscess, it can lead to further enlargement of the pus cavity, increasing the size of the infected wound and the focus of infection, causing more severe pain and symptoms of systemic infection in the patient. Hemorrhoids, on the other hand, can be managed with conservative medication to alleviate symptoms. Surgical treatment is considered only when there are recurrent flare-ups, severe pain, significant prolapse, and worsening bleeding.
How to treat recurrent perianal abscess?
If a perianal abscess has already been treated surgically, it is necessary to develop good dietary and bowel habits postoperatively to reduce the likelihood of recurrence. However, recurrence may still occur due to poor diet and bowel habits of the patient. If there is pain or discomfort at the site of the local wound of the perianal abscess, it is advisable to go to the hospital as soon as possible for an anal examination and perianal ultrasound to confirm if it has recurred. If it is confirmed to have recurred, early surgical treatment is necessary to prevent further expansion of the local infection focus or aggravation of the infection, which would increase the difficulty of treatment later.
What should I do if the perianal abscess bursts?
Since a perianal abscess is an acute symptom of a local skin infection around the anus, during the acute phase of a perianal abscess, an abscess cavity and pus formation generally occur within about a week. As the disease worsens and progresses, the perianal abscess will rupture about a week later. If the perianal abscess ruptures, it may have already formed an anal fistula. A perianal abscess and an anal fistula represent two different stages of the disease, and both require surgical treatment. The main surgical treatment for anal fistulas is fistulotomy with seton placement, and care must be taken to drain and disinfect the local wound post-surgery to prevent pseudohealing of the wound.
How to operate on a perianal abscess
The surgical methods for perianal abscess vary depending on the location of the lesion. If it is a simple ischiorectal fossa subcutaneous abscess, a one-time incision and drainage surgery is generally used. The local wound is debrided and necrotic tissue is removed. After trimming the wound, it is important to maintain clear drainage of the local wound. Local application of gauze strips for compression and drainage treatment can be used. If the abscess is in the ischioanal fossa or the pelvirectal space, considering that the location of the lesion is deep, a one-time incision and seton drainage radical surgery may be required for the perianal abscess. Post-surgery, thorough disinfection and drainage of the local wound are also necessary.
Should surgery be performed if there are no symptoms of anal fistula?
If an anal fistula is in its acute phase, the main clinical symptoms are intermittent discharge of pus from the external opening, or pain and itching. If there are no symptoms, and only the external and internal openings along with the fistula tract exist, surgery is still required because the absence of symptoms temporarily does not guarantee that an acute episode will not occur later. During an acute episode, there will be local tissue and skin inflammation, redness, heat, and severe pain. If an anal fistula is not surgically treated for a long time, it may lead to an increase in the number of branches of the fistula or thickening of the fistula wall, and it may even spread to the pelvic cavity. Therefore, once an anal fistula is discovered, it is necessary to perform surgery as soon as possible. Early treatment has significant benefits for wound recovery and the difficulty of the operation.
What to do about the false healing of anal fistula?
If a false healing of the wound occurs after local surgical excision of an anal fistula, it is mainly due to improper dressing changes by the patient and a lack of timely observation of the local wound. It is recommended to open the superficially healed wound to allow it to regrow. In particular, the patient needs to change the dressing and observe the wound daily to prevent the situation where the internal part of the wound has not healed, but the external opening appears healed. During dressing changes, hemorrhoid creams and other drugs that promote mucosal healing can also be applied locally and inside the anal canal to further promote the healing of the internal opening. Only when the internal opening has fully grown should treatment that promotes healing of the external opening be applied. (Please use medication under the guidance of a professional physician, and do not self-medicate.)
Can anal fistulas be left untreated indefinitely?
If a patient is diagnosed with an anal fistula, it must not be left untreated. If an anal fistula is not actively treated over a long period, it can easily lead to thickening of the fistula tract or an increase in branching. Moreover, after long-term repeated inflammatory stimulation, some fistula tracts are prone to malignant transformations. Therefore, it is recommended that patients with anal fistulas seek symptomatic treatment as soon as they are diagnosed. The primary method of treating anal fistulas is surgical. The main surgical approach for an anal fistula is fistulotomy with seton placement, which involves removing the local fistula tract wall while preserving the function of the patient's sphincter muscle. After the surgery, patients need to follow a light diet to avoid an increase in local secretions, which can lead to inflammatory stimulation and even the recurrence of the anal fistula.
