Will anal fistula cause bleeding during bowel movements?
If an anal fistula occurs, during the acute phase of the anal fistula, or when the internal and external openings of the anal fistula are ulcerated, there may also be bleeding during defecation. However, the bleeding from defecation due to an anal fistula is generally minor, and occasionally pus may also be discharged from the anus, or pus may be discharged from the external opening, causing itching or stinging of the skin around the external opening. If local pain or bleeding from defecation occurs with an anal fistula, prompt local anti-inflammatory treatment is needed; an anti-inflammatory ointment can be chosen for local application. However, the fundamental treatment for an anal fistula still requires surgery. It is generally recommended to directly perform a fistulotomy with seton placement to completely heal the fistula and prevent recurrent episodes.
What is the internal opening of a perianal abscess?
The internal opening of a perianal abscess primarily refers to the anal crypt. It forms an infection site due to prolonged, repeated inflammatory infections, generally characterized by distinct pus discharge from the internal opening. Therefore, perianal abscesses tend to form a local internal opening near the anus along with intermittent pus discharge. If the perianal abscess acutely flares up or the pus cavity spreads, it might also rupture, causing pus to exit from an external opening, thereby leading to the formation of a typical anal fistula. During the acute phase of a perianal abscess, if there is local internal opening pain or pus discharge, it is recommended to seek surgical treatment as soon as possible. The primary method of surgery is aimed at radical treatment in one session. The principle involves opening the local pus cavity to allow for the discharge of pus, followed by a thorough debridement and removal of the local infection site. However, it is necessary to preserve the function of the local anal sphincter. If needed, a seton procedure may also be performed.
What are the symptoms of anal fistula?
The clinical symptoms of anal fistula are mainly manifested as intermittent discharge of secretion from the local external opening near the anus, accompanied by varying degrees of pain in the anal area, and occasionally, pus is expelled with the stool. The main reason for its formation is that the anal fistula not only has an external opening, but also an internal opening near the dentate line of the anal canal. The internal opening discharges pus intermittently due to the stimulation of local inflammation. The composition of an anal fistula includes the internal and external openings, as well as the fistula tract that connects them; therefore, simply using medication cannot completely eliminate this lesion. The treatment of anal fistula is mainly surgical, aimed at removing the local lesion, with the principle of preserving the anal sphincter to avoid damage to it, which could affect the patient's future life.
How many days of antibiotic injections are needed to treat a perianal abscess?
During the acute phase of a perianal abscess, the main focus is on the nature of the local abscess. If it is a hard swelling without pus formation, anti-inflammatory injections or antibiotics can be used for symptomatic treatment. Generally, a five to seven-day course of antibiotic and anti-inflammatory treatment can reduce the local swelling, but it cannot guarantee a 100% chance of non-recurrence in the future. If a local pus cavity or swelling has already formed, and there is pus formation, simply using anti-inflammatory injections for symptomatic treatment will not be curative. Surgery is also required, mainly involving opening the local pus cavity, cleaning out the pus thoroughly, and removing local infection foci to promote normal growth of fresh granulation tissue, which could then lead to the healing of the local wound.
Can I eat eggs with a perianal abscess?
Patients with perianal abscess can eat eggs, but during the acute onset period of a perianal abscess, besides sticking to a light diet, it is more important to seek surgical treatment as soon as possible. A perianal abscess is an acute infectious disease near the anal sinuses. Typically, it presents with severe local pain in the anus. Once pus forms, it is encapsulated in the abscess cavity and needs to be surgically drained as soon as possible to remove the infection thoroughly. This helps to prevent further enlargement of the abscess cavity and worsening of the condition. Furthermore, in the early postoperative period, patients can consume liquid foods and eat eggs in moderation or other easily digestible foods. However, they should avoid spicy and irritating foods such as chili peppers and seafood.
What is causing the stabbing pain in the wound half a year after perianal abscess surgery?
Six months after surgery for a perianal abscess, if there is local pain at the wound site, it is first necessary to rule out the presence of local infection and recurrence. To differentiate between infection and recurrence, it is necessary to conduct a digital rectal examination and a perianal ultrasound to confirm the diagnosis. If infection and recurrence are ruled out, consider the possibility that the pain may be due to contraction and softening of the scar tissue at the site of the perianal abscess surgery, leading to painful stinging at the wound. Local application of anti-inflammatory ointments or gels can be used to treat the inflammation. If the pain or discomfort is severe, Chinese herbal washes or dilute salt water can be used for fumigation and hot compresses on the local scar.
What should not be eaten with a perianal abscess?
During the acute phase of a perianal abscess, it is not advised to consume overly spicy and stimulating foods, drink alcohol, or eat much lamb, seafood, and other aggravating items. This is because a perianal abscess is a local infectious disease around the anus. Therefore, it is necessary to undergo surgery as soon as possible during an outbreak to prevent the spread of the abscess and increase the difficulty of treatment later. The surgical methods mainly include incision and drainage and one-time radical surgery. However, when there is a local fistula or changes in the sphincter, a fistulotomy with seton placement can also be chosen. Post-surgery, it is crucial to pay attention to the local wound drainage and dressing changes, which are very important for wound healing. It is essential to ensure proper drainage and thorough dressing changes to avoid pseudohealing or recurrent infection of the wound.
Early symptoms of perianal abscess
When perianal abscesses occur, there are usually significant triggers, most commonly seen after acute diarrhea or when a patient's immunity has recently declined. In the early stages of a perianal abscess, there are sudden symptoms of localized swelling and pain around the anus, accompanied by a sensation of heaviness. As the local abscess cavity enlarges and the infection worsens, the patient may also experience general weakness, fever, and even a decrease in appetite. During the acute phase of a perianal abscess, due to severe local pain, patients are unable to carry on with normal life activities, including sitting and walking. The pain may further involve pelvic muscles and nerves, leading to difficulties with defecation and urinary retention.
What are the consequences of not treating an anal fistula?
If an anal fistula is not promptly treated with surgery, it may lead to an increase in the number of local branches or a thickening of the fistula wall. If the branches of the anal fistula extend to the ischiorectal fossa, it may also lead to pelvic infections. Moreover, if the anal fistula persists for a long time or if there is significant local inflammatory stimulation, it may even lead to cancerous changes in the fistula. Therefore, once an anal fistula is discovered and diagnosed, it is recommended to promptly undergo surgical treatment with fistulotomy and seton placement. Post-surgery, it is crucial to ensure thorough disinfection of the local wound, debridement, and dressing changes, which are very important for the recovery of the wound. This helps prevent pseudohealing, ensuring that the anal fistula heals completely and preventing recurrent episodes.
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.
