Draining a Pilonidal Abscess: Controversies vs. Best Practices

By Dr. Jeffrey Sternberg

Draining a pilonidal abscess (also referred to as I&D, or incision and drainage) should be in the bag of tricks of any emergency room, urgent care doctor, or surgeon. But the practice is very variable, and many patients suffering from a chronic case of Pilonidal Disease have unsatisfactory experiences.

As a surgeon specializing in treating pilonidal patients with the Cleft Lift procedure, there are a few main issues with the practice of draining an infected pilonidal abscess that I’ve observed. Many doctors still endorse some old-fashion procedures. I prefer to promote more well-established best practices that some consider controversial in the field.

1) When draining a pilonidal abscess, try and make the incision away from the midline if possible. Incision made in the buttock cleft midline are hidden and resist draining and healing, while those off to the side drain better and more likely to heal over time. Sometimes, however, the abscess is only drainable in the midline, and this forces the doctor’s hand.

2) When draining a pilonidal abscess, doctors should make a larger rather than a small incision to facilitate drainage. Makes sense.

3) The shape of the incision is very important. Draining an abscess with a linear stab incision doesn’t permit drainage. Incisions need to be elliptical so that the skin doesn’t heal before the abscess fully drains. Elliptical incisions allow abscesses to drain over days and provide the most rapid recovery from an acute abscess. Aspiration with a needle and syringe is not a good practice and rarely if ever works.

4) Failure for an I&D wound to heal may be a consequence of the pilonidal abscess wanting to form a sinus and continue to decompress itself rather than a poorly performed I&D. This may be a natural progression of the disease process.

5) Lastly (and this may be the most controversial portion of this post), doctors should stop packing wounds. I was taught to pack wounds during my residency but in fellowship I was taught the opposite and it was a game changer. Packing wounds acts like a cork keeping infection inside. Having patients or their family members repack wounds is painful, embarrassing, and counterproductive. Incisions made to drain a pilonidal abscess should be elliptical, at least a centimeter in size, and not packed. After drainage patients should soak in a tub several times a day and they will typically feel better within 24 hours of the procedure, if not in hours.

This is evidence based and here’s a useful article “Packing versus non-packing outcomes for abscesses after incision and drainage.”

After many years performing major abdominal operations including open and laparoscopic resections for colon cancer, rectal cancer, Crohn’s disease, and Ulcerative colitis, I have chosen to concentrate my efforts in a few highly specialized areas of surgery where I feel I can make the greatest positive impact on patients.
