What Treatment Is Needed for an Abscess Near the Large Intestine After Fistula Surgery?

Hello,

An infection or abscess near the large intestine after fistula surgery needs proper medical evaluation. An abscess is a pocket of pus that can develop when bacteria cause an infection. Since you have mentioned an abscess higher up near the large intestine after fistula surgery, it is important to consult a gastroenterologist or a colorectal/general surgeon as soon as possible. The correct treatment depends on the location, size and cause of the abscess.

What could cause an abscess after fistula surgery?

• Persistent or recurrent infection: Infection may remain in the tissues or develop again after the operation.
• A remaining or recurring fistula: An abnormal passage between the intestine or anal canal and nearby skin can allow bacteria to spread and cause repeated infections.
• A deeper abscess: A pocket of pus may develop in deeper tissues around the rectum or pelvis and may not be visible externally.
• Inflammation of the intestine: Conditions such as Crohn's disease can sometimes cause intestinal inflammation, fistulas and abscesses.

These are possible causes, not a confirmed diagnosis. An examination and review of your previous operation records are needed to identify the actual cause.

What treatment be needed?

• Examination by a specialist: A colorectal surgeon or general surgeon experienced in fistula treatment can assess the operated area. A gastroenterologist may also be needed if the large intestine itself is affected.
• Scans and investigations: Depending on the suspected location, the doctor may recommend a CT scan or MRI of the pelvis, blood tests and other investigations to locate the abscess and assess the infection.
• Antibiotics: The doctor may prescribe antibiotics to control the infection. However, antibiotics alone may not clear an abscess that requires drainage.
• Abscess drainage: If a collection of pus is present, the doctor may need to drain it through a suitable procedure. The method depends on the abscess's location and size.
• Further fistula treatment: If a fistula is still present or has returned, additional treatment may be required after the infection is controlled.

What precautions should you follow?

• Take prescribed medicines as directed. Do not start antibiotics or stop them early without medical advice.
• Keep the operated area clean and follow the surgeon's wound-care instructions.
• Drink enough water and eat fibre-rich foods if your doctor has not advised dietary restrictions.
• Avoid straining during bowel movements. Ask your doctor whether a stool softener is suitable.
• Attend follow-up appointments and carry your previous operation notes, discharge summary, scan reports and prescriptions.
• Do not squeeze the swollen area or try to drain the abscess yourself.

When should you seek urgent medical care?

Seek urgent medical attention if you have fever or chills, increasing abdominal or rectal pain, worsening swelling, pus discharge, vomiting or difficulty passing stools. Severe abdominal pain, a swollen abdomen, confusion or feeling faint require emergency assessment. A deep abscess can sometimes cause serious infection, so do not delay care while waiting for a routine appointment.

Which doctor should you consult?

Because the abscess is described as being higher up near the large intestine after fistula surgery, start with the surgeon who performed your operation or consult a colorectal surgeon/general surgeon experienced in fistula and deep abscess treatment. A gastroenterologist should also assess the case if the doctor suspects a problem involving the large intestine.

To guide you more specifically, please share when the fistula operation was performed, whether a CT or MRI scan has confirmed the abscess, and whether you currently have fever, abdominal pain or pus discharge.

Wishing you and your family good health always.
