Anal Polyp Surgery | Anal Fibroma Surgery: Information on the Procedure and Recovery

An anal polyp is a benign growth of mucous membrane tissue in the anal region, often referred to as an anal fibroma. It usually develops as a result of chronic irritation in the anus, such as from straining during bowel movements, recurrent constipation, or an accompanying inflammatory condition like hemorrhoids or an anal fissure. Depending on its location, the polyp may be found in the anal canal or at the junction with the rectum and can vary in size and shape. Small polyps are often harmless and cause little or no discomfort. However, as they grow larger, a sensation of a foreign body may develop, which patients find unpleasant. Pain—especially during bowel movements—discharge from the anal area, or slight bleeding are also possible symptoms. Since anal polyps resemble other conditions in appearance and are often misdiagnosed, a specialist examination by a doctor is recommended to establish the correct diagnosis and determine the appropriate course of action.

Anal polyps do not always cause symptoms and are therefore often first detected during a routine examination at the doctor’s office. If there are no symptoms, treatment is not immediately necessary. Nevertheless, regular checkups are advisable to detect any changes in the findings early on and to rule out a possible condition affecting the anal area.

If symptoms are present, a more thorough evaluation by a doctor is necessary. Pain, recurrent bleeding, discharge, or a pronounced sensation of a foreign body may indicate that the polyp is growing in size or becoming trapped in the anal canal. You should also see a doctor promptly if you experience difficulty with bowel movements, increasing swelling, or painful irritation around the anus.

Anal polyps often occur in combination with hemorrhoids or a chronic anal fissure. In these cases, surgical removal is often advisable, as the symptoms can exacerbate one another and the healing process may be delayed without surgery. If there is also suspicion of another rectal condition, a thorough diagnosis is performed before surgery to determine the appropriate course of action.

Surgery is particularly recommended if severe pain occurs, bleeding is observed repeatedly, or functional disorders—such as fecal incontinence—are a risk. Removal is also necessary for certain types of polyps that may pose an increased risk of complications. The goal of treatment is to alleviate symptoms, prevent further problems with the anus, and improve patients’ quality of life in the long term.

If conservative treatment is insufficient or no longer appropriate due to severe symptoms, the anal polyps are removed through surgery. The procedure is typically performed on an outpatient basis and usually takes between 30 minutes and 1 hour. Depending on their location and size, the procedure may be performed under local anesthesia or general anesthesia. The goal is to completely remove the abnormal tissue and to clean the wound as gently as possible.

Prior to surgery, the doctor conducts a thorough examination and makes a diagnosis, often at a specialized clinic or in a hospital. During this process, the doctor determines whether the condition is a single anal polyp or another condition, such as hemorrhoids. This distinction is important for determining the appropriate course of action and avoiding potential complications.

The surgery itself is usually performed using an electric loop or a similar instrument. The polyp is precisely removed without unnecessarily damaging the surrounding tissue. The procedure is considered largely painless, as the mucous membrane in the anal canal does not transmit pain while the patient is under anesthesia. In many cases, the wound is not closed with stitches but is allowed to heal open, which supports the natural healing process. 

After removal, a compress is often gently inserted to absorb any minor bleeding. Slight bleeding in the first few days is not unusual and is usually not a cause for concern. To support wound healing, the doctor may prescribe appropriate medication to reduce pain, such as pain relievers like ibuprofen. The goal of treatment is to reduce strain during bowel movements, prevent constipation, and facilitate the fastest possible healing.

The subsequent course of treatment generally depends on the initial findings. Often, there is a concurrent anal condition that is closely related to the polyps. 

This includes, in particular, chronic anal fissures. Consequently, the time required for complete healing varies between a few days and several weeks, depending on the medical diagnosis.

To actively support the healing process, your doctor will recommend:

• Sitz baths with anti-inflammatory substances
• A high-fiber diet and 
• Adequate fluid intake 

These measures help prevent constipation so that the wound area is not compromised by hard stools.

In principle, there is a possibility of minor post-operative bleeding, which, however, usually stops quickly. Careful hygiene is crucial to minimize the risk of impaired wound healing. 

Your doctor will provide you with detailed information on specific care measures. 

These include, above all:

• Keeping the wound clean after each trip to the bathroom and 
• Avoiding the use of soap until the wound has completely healed

In the first few days, you will be given a pain reliever and a mild laxative. This is intended to prevent pressure on the sphincter muscle. 

The long-term prognosis depends on your medical history and your own preventive measures. In principle, it is possible for polyps to develop again. 

A healthy lifestyle, sufficient exercise, and a high-fiber diet help reduce the risk.

Anal polyps originate from chronic irritation around the anal canal. In the early stages, they are small growths that are harmless. 

As they progress, they may grow larger, potentially causing pain and difficulty with bowel movements. Your proctologist, as a specialist in the digestive tract, will inform and advise you on the straightforward procedure for removing polyps.
