Post-Surgery Complications: Swelling Around the Anus - Surgery

Postoperative care for hemorrhoids and the anal region?


A year ago, I underwent surgery for internal and external hemorrhoids.
At the end of September, I noticed that the skin around the anal area, which was left over from the surgery, swells noticeably (it is clearly connected to the skin inside the anus).
The swelling is particularly pronounced when walking or sitting.
I have used ointments and suppositories, but there has been no improvement.
What could this issue be? Is it necessary to have another surgery? Will surgery lead to more complications? Could this be a recurrence of hemorrhoids or possibly a fistula? Thank you.

This is residual skin tags or remaining external hemorrhoidal tissue after surgery.
If there is no pain or bleeding, it can be left alone.
However, if it causes discomfort that affects daily activities, surgical removal can be considered.
Since the area is relatively small, there are unlikely to be any significant long-term complications.
The recurrence of hemorrhoids is more related to lifestyle and bowel habits.

Post-surgery complications, particularly around the anal region, can be concerning and may arise from various underlying issues. In your case, having undergone surgery for anal fissures or hemorrhoids a year ago, the swelling you are experiencing around the anus could be attributed to several factors.

Firstly, it is important to understand that after any surgical procedure, especially in sensitive areas like the anal region, there can be residual tissue changes. The swelling you describe, particularly when exacerbated by activities such as walking or sitting, may indicate inflammation or irritation of the surrounding tissues. This could be due to scar tissue formation, which is common after surgery. Scar tissue can sometimes become fibrous and may not have the same elasticity as the surrounding tissue, leading to discomfort and swelling.

Another possibility is the development of a perianal abscess or fistula. An abscess is a localized collection of pus that can occur if there was an infection during the healing process. A fistula, on the other hand, is an abnormal connection between the anal canal and the skin, which can develop after surgery if the healing process is disrupted. Both conditions can cause swelling, pain, and discomfort, particularly during activities that put pressure on the area.

The use of topical ointments and suppositories may help alleviate some symptoms, but if there is no improvement, it is crucial to seek further evaluation from a healthcare professional. They may recommend imaging studies or a physical examination to assess the area more thoroughly.

Regarding the need for another surgical intervention, it largely depends on the underlying cause of the swelling. If it is determined that there is a significant issue such as a fistula or an abscess, surgical intervention may be necessary to address the problem effectively. However, surgery does carry risks, including the potential for additional complications such as infection, increased pain, or further scarring, which could lead to more discomfort.

As for the concern about developing hemorrhoids again, it is possible, especially if there are contributing factors such as constipation, straining during bowel movements, or prolonged sitting. Maintaining a healthy diet rich in fiber, staying hydrated, and practicing good bowel habits can help mitigate this risk.

In summary, the swelling around your anus could be due to several factors, including scar tissue formation, inflammation, or the development of an abscess or fistula. It is essential to consult with a healthcare provider for a thorough evaluation to determine the exact cause and appropriate treatment. If surgery is deemed necessary, discussing the potential risks and benefits with your surgeon will help you make an informed decision. Regular follow-ups and monitoring of your symptoms will also be crucial in managing your condition effectively.
