Generally, perianal abscesses do not cause weight loss. Typically, perianal abscesses are caused by common bacteria infecting the spaces around the anus and rectum, leading to an acute purulent infection. When an abscess forms, it can cause sudden swelling and pain in the perianal area, with episodic increases in pain. However, if the abscess is caused by tuberculosis bacteria, it can lead to a chronic condition and systemic wasting diseases, which may present symptoms such as night sweats, feverish feelings, etc. Chronic diseases can cause weight loss.

How to find the internal opening of a perianal abscess?

The internal opening of a perianal abscess is mainly identified through digital rectal examination and with the aid of a probe and perianal ultrasonography. Typically, during the onset of a perianal abscess, there is noticeable redness, swelling, heat, and pain around the anus. Inside the anal canal, digital rectal examination and anoscopy reveal swollen mucosa at the anal crypt, accompanied by the discharge of pus. Using a probe for exploration can clearly identify the presence of the internal opening locally. Once the internal opening of a perianal abscess is located, prompt surgical treatment is necessary. Surgery for perianal abscesses generally involves a one-time radical procedure complemented by incision and drainage. If an internal opening exists and involves the sphincter, further surgery involving incision, drainage, and seton placement may be required.

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.

How should a perianal abscess be treated effectively?

During the acute phase of a perianal abscess, there is generally severe pain in the anal area, accompanied by redness and throbbing of the skin, and there may be a pus cavity or pus encapsulation under the skin. The treatment of perianal abscess is mainly surgical. The surgical method is incision and drainage, combined with a one-time radical surgery. If the infection involves the local sphincter or has already formed a clear fistula, further incision and ligation surgery may be required. After surgery, it is necessary to thoroughly disinfect and change the dressings of the wound to prevent excessive granulation or the formation of false healing at the local wound. Postoperative diet should consist mainly of light, liquid foods, and spicy and irritating foods should be avoided.

Can a perianal abscess burst on its own after it forms pus?

After an anal abscess becomes purulent, one should not attempt to rupture it on their own. If purulence occurs, it is advised to perform local disinfection under a doctor's supervision, followed by incision and drainage or pus aspiration to prevent further infection. Attempting to rupture it on your own can easily lead to further aggravation of the local infection. After an anal abscess becomes purulent, the choice of incision location is crucial; once cut, it is necessary to maintain unobstructed drainage to avoid subsequent infection or even necrotizing fasciitis. In clinical practice regarding anal abscesses, it is advised to visit a colorectal surgery department at a hospital as soon as the abscess is detected, to undergo procedures such as incision and drainage or radical surgery of the anal abscess to avoid the later development of anal fistulas or necrotizing fasciitis. Post-surgery, medications such as red oil gauze strips, anal cleansing solutions, and aureomycin ointment are recommended for dressing changes.

The difference between perianal abscess and hemorrhoids

Perianal abscess and hemorrhoids are two different types of common anorectal diseases. When a perianal abscess occurs, the onset is generally sudden and there is severe pain in the anal area. Under the skin of the anal area or inside the anal canal, a submucosal abscess forms, encapsulating pus. Surgical treatment is required as soon as possible to prevent further spread of the abscess cavity. Hemorrhoids, on the other hand, are caused by the long-term and repeated accumulation of local tissues in the anal area, leading to the formation of blood clots or varicose vein masses. These generally occur near or around the dentate line, and may also be accompanied by skin tags of external hemorrhoids.
