Post-Surgery Pain After Perianal Abscess: Causes and Concerns - Surgery

Postoperative issues following perianal abscess surgery?


Hello, I underwent surgery for a perianal abscess nearly three and a half months ago, and the doctor has indicated that the wound has healed.
However, I still experience pain near the coccyx area after bowel movements or prolonged sitting.
The doctor mentioned that during the incision and drainage, a small portion of the anal sphincter had to be cut, and since the sphincter was inflamed during the abscess, it may have resulted in adhesions between the sphincter and surrounding tissue during healing, causing pain.
When the pain occurs, I take anti-inflammatory pain relievers (not antibiotics), and by the next day, the pain is usually less severe.
Given my situation, could the pain truly be due to adhesions, or could it be caused by the formation of an anal fistula? Thank you for your response.

After anal abscess surgery, there is a 50% chance that it may develop into an anal fistula.
Both conditions can occur, and it is essential to have a physician conduct a personal examination to determine the exact issue.

More Info


After undergoing surgery for a perianal abscess, it is not uncommon to experience lingering pain, especially in the area around the anus and tailbone. Your description of pain after bowel movements or prolonged sitting is consistent with the healing process following such a procedure. The fact that your doctor has indicated that the wound has healed is a positive sign, but it does not necessarily mean that all discomfort will immediately resolve.

The pain you are experiencing could indeed be related to the healing of the anal sphincter muscle. During the incision and drainage of the abscess, the surgeon may have had to cut through a small portion of the anal sphincter. This can lead to inflammation and subsequent scarring, which might cause adhesions (or "sticky" areas) between the sphincter and surrounding tissues. These adhesions can result in discomfort or pain, particularly when the area is stressed, such as during bowel movements or prolonged sitting.

Additionally, the possibility of a fistula (an abnormal connection between the anal canal and the skin) cannot be entirely ruled out. Fistulas can develop after an abscess, especially if the abscess was extensive or if there was significant tissue damage. Symptoms of a fistula can include persistent pain, discharge, or swelling in the anal area. If you notice any new symptoms, such as increased pain, discharge, or changes in bowel habits, it would be prudent to consult your healthcare provider for further evaluation.

In terms of management, it is good that you are taking anti-inflammatory pain medications as needed. These can help alleviate discomfort and allow you to engage in daily activities more comfortably. However, it is essential to monitor your symptoms closely. If the pain persists or worsens, or if you develop any new symptoms, you should return to your doctor for a thorough examination. They may perform a physical examination or imaging studies to rule out any complications, such as a fistula or other underlying issues.

In the meantime, consider the following strategies to help manage your symptoms:
1. Dietary Adjustments: Ensure that you are consuming a high-fiber diet to promote regular bowel movements and reduce straining. Staying well-hydrated can also help soften stools.

2. Warm Sitz Baths: Taking warm sitz baths can help soothe the area and promote relaxation of the anal sphincter, which may alleviate some discomfort.

3. Avoid Prolonged Sitting: If possible, try to avoid sitting for extended periods, as this can exacerbate pain. Consider using a cushion or a specialized seat to relieve pressure on the area.

4. Gentle Exercise: Engaging in light physical activity can promote circulation and healing, but be cautious not to strain the area.

5. Follow-Up Care: Regular follow-up appointments with your healthcare provider are essential to monitor your recovery and address any concerns that may arise.

In conclusion, while it is possible that the pain you are experiencing is due to adhesions from the surgical site, it is also important to remain vigilant for signs of complications such as a fistula. Open communication with your healthcare provider will be key in managing your recovery effectively. If you have any doubts or concerns, do not hesitate to seek medical advice.
