How to recover from fecal incontinence?
For fecal incontinence, we must first conduct an effective evaluation and complete relevant examinations. For instance, we need to perform anal canal pressure measurements and examine the anal sphincter muscle imaging. Through these examinations, we can determine the extent of fecal incontinence and then adopt corresponding treatment methods. For fecal incontinence, we can initially choose conservative treatments, such as treatment with biofeedback therapy.
What is the most accurate test for anal fistula?
As a common disease in proctology, simple anal fistulas can be diagnosed through visual inspection and palpation. For high-positioned complex anal fistulas, which cannot be accurately assessed through just visual inspection and palpation, the use of instruments may be necessary. Currently, magnetic resonance imaging (MRI) is recommended as the most accurate method for evaluating anal fistulas, and it is considered the gold standard for examining the course of the fistula tract and the location of the infection.
causes of anal fistula
Anal fistula is one of the common diseases in proctology. The formation of an anal fistula is caused by infection of the anal sinuses and anal glands. Due to damage to the anal sinuses and anal glands, bacteria from the intestines enter these areas. As immunity weakens, the bacteria cause localized inflammation, which then leads to the formation of an abscess. After the abscess bursts, an anal fistula forms. This is the pathogenesis of anal fistula.
What will happen if an anal fistula is not treated?
An anal fistula is a chronic fistula and duct caused by an infection of the anal sinuses. If not treated, an anal fistula may repeatedly flare up. The consequences of repeated occurrences can lead to abscesses, peripheral spreading, and eventually extensive spreading of the loose tissue around the anus, which in severe cases may damage the anal muscles, leading to anal incontinence. If an anal fistula persists for a long time, there is also a possibility of malignant transformation.
Symptoms of thrombosed external hemorrhoids
Thrombotic external hemorrhoids are a type of external hemorrhoids. They are caused by the rupture of blood vessels in external hemorrhoids, leading to blood spillage, which in turn causes pain and inflammation. The symptoms manifest as a sudden hard lump near the anus. If visible, subcutaneous purple bruises can be seen, and pressing on it causes pain. Generally, surgical treatment is required.
Is the probability of anal fistula turning into cancer high?
An anal fistula, formed due to an anal gland infection, carries a higher risk of malignant transformation if the infection and inflammation are recurrent and persistent, particularly over a long period exceeding five years. Therefore, it is strongly recommended that anal fistulas exceeding five years should be given sufficient attention and surgical treatment should be pursued promptly to prevent malignancy.
Anal fistula etiology
The cause of an anal fistula is due to infection of the anal glands. In normal human anatomy, there is a location at the junction of the rectum and the anal canal called the anal sinus or anal gland, which is relatively weak. If it is damaged, intestinal bacteria can enter the anal gland, causing inflammation. Over time, the infected anal gland leads to further abscesses towards the perianal space, causing a perianal abscess. After the perianal abscess ruptures, it further develops into an anal fistula.
The difference between rectal prolapse and external hemorrhoids.
Rectal prolapse is the protrusion of the rectal mucosa, which manifests as an eversion of the mucosa presenting as pink-colored, cylindrical protrusions. These can usually be manually repositioned back into the anus, appearing smooth once repositioned. In contrast, external hemorrhoids are mostly caused by varicosities and are the same color as the skin. They cannot be completely repositioned manually, which distinguishes them from rectal prolapse.
What color is the pus from an anal fistula?
An anal fistula is a sinus tract and fistula formed from an infection of the anal sinuses and glands. During the infection phase, there is a possibility of swelling, pain, and pus discharge. This discharge may be yellow pus or pus mixed with blood. Regardless of the color, it is crucial to seek prompt medical treatment at a hospital and undergo thorough treatment, rather than attempting conservative treatment on one's own.
What department should I see for anal fistula?
Anal fistula is caused by infection of the anal sinuses and glands. It manifests as hard lumps or cord-like objects around the anus, and may involve recurrent swelling, pain, and discharge of pus. In such cases, it is necessary to consult a colorectal surgeon. Generally, if diagnosed with an anal fistula, surgical treatment is required, as conservative treatment usually does not result in a cure.
