From the Guidelines

The management of a fistula on the lower buttock typically requires referral to a colorectal surgeon for surgical intervention, with the primary treatment being a procedure called fistulotomy or seton placement, depending on the complexity of the fistula. The decision to perform fistulotomy or seton placement should be made by a specialist, taking into account the location and complexity of the fistula, as well as the patient's overall health status 1.

In the meantime, before surgical intervention, the patient can be managed with:

  • Antibiotics such as metronidazole 500mg three times daily or ciprofloxacin 500mg twice daily for 7-10 days to control infection 1
  • Pain management with acetaminophen or NSAIDs
  • Sitz baths (warm water soaks) for 15-20 minutes, 2-3 times daily to help with discomfort and promote healing
  • Maintaining good hygiene of the area, including gentle cleaning after bowel movements
  • A high-fiber diet and adequate fluid intake to help prevent constipation, which could exacerbate the condition

It is essential to note that fistulas rarely heal on their own and can lead to chronic drainage, pain, and recurrent infections if left untreated 1. Therefore, prompt referral to a specialist and appropriate management are crucial to prevent complications and improve the patient's quality of life.

Some key points to consider when managing a patient with a fistula on the lower buttock include:

  • The importance of a thorough medical history and physical examination to identify any underlying conditions that may be contributing to the development of the fistula 1
  • The need for careful consideration of the patient's overall health status and any potential contraindications to surgery 1
  • The importance of maintaining good hygiene and preventing constipation to promote healing and prevent complications 1

Management and Treatment of Fistula on Lower Buttock

For a fistula on the lower buttock, it is essential to refer to a specialist, such as a colorectal surgeon or a gastroenterologist, for proper evaluation and treatment.

  • The management and treatment of anal fistulas can vary depending on the complexity and location of the fistula, as well as the underlying cause 2.
  • Simple fistulas can be treated with conventional surgical options, such as laying open of the fistula tract, while more complex fistulas may require sphincter-preserving procedures, such as ligation of intersphincteric fistula tract or anal fistula plug 2.
  • In some cases, medications such as ciprofloxacin or metronidazole may be used to treat perianal fistulas, especially in patients with Crohn's disease 3.
  • For recurrent anal fistulas, the management can be more challenging, and the treatment approach may need to be individualized based on the specific circumstances 4.

Interim Management

While waiting for a specialist appointment, it is crucial to keep the affected area clean and dry to prevent infection.

  • Patients can use warm water to clean the area and pat it dry with a clean towel.
  • Avoiding tight clothing and using a soft, absorbent pad to protect the area from friction and moisture can also help.
  • Over-the-counter pain relievers, such as acetaminophen or ibuprofen, can be used to manage pain and discomfort, but it is essential to follow the recommended dosage and consult with a healthcare professional before taking any medication.

Specialist Referral

Referring to a specialist, such as a colorectal surgeon or a gastroenterologist, is crucial for proper evaluation and treatment of a fistula on the lower buttock.

  • The specialist will assess the fistula and develop a personalized treatment plan, which may include surgery, medication, or a combination of both 2, 5.
  • The treatment approach will depend on the complexity and location of the fistula, as well as the underlying cause, and the specialist will discuss the options and recommendations with the patient.
