Dr Immerman performs the “Cleft-Lift” procedure (Bascom Procedure).

What are pilonidal cysts?
A pocket of infection that occurs in the tailbone area is called a “pilonidal” cyst or abscess. These infections begin as enlarged pores in the crease between the buttocks. Pieces of hair can enter these pores, burrow their way underneath, and cause infection. Sometimes this causes minor irritation, but other times it can cause a painful infection that requires surgical drainage. Patients can have different degrees of symptoms from this problem. Once pilonidal infections begin, they may continue to cause problems unless surgically treated.

Treatment of pilonidal disease can be a challenging and frustrating experience for both the patient and the physician. Dealing with this problem has been a challenge that Dr. Steven Immerman has accepted since he began his surgical practice in 1981. His current results are excellent: in 2013 he published a paper which described that approximately 90% of his patients demonstrated complete primary healing after one procedure, and 98% complete healing after a second procedure.

Since that time, his success rate with the last 100 new patients has increased to 97% complete healing after one procedure. Of the patients who had the cleft-lift from Dr Immerman as their first operation for their pilonidal disease, none of the patients required a second operation. Of the more complicated patients who required a revision of previous failed operations, 6% required a second operation to achieve complete healing.

“When searching the surgical literature one finds literally dozens of different procedures that have been proposed for this disease. I have personally tried many of these methods, and after much experimentation and frustration I have adopted a procedure that is very successful.

Pilonidal Cleft-Lift Surgery Dr Immerman's ArticleWhy most surgery for Pilonidal Disease fails

Surgeons are taught to remove all the visible disease and either attempt closure or leave the wound open to heal secondarily. What both of these approaches fail to address is that the disease process is caused by the deep buttock crease (called either the natal cleft or gluteal cleft). A deep buttock crease remains moist at almost all times, promotes growth of bacteria, and creates negative pressure which sucks hairs into enlarged pores. Any procedure that does not address the shape of the buttock crease has a high failure rate; and that failure usually show up as new pilonidal disease, or a wound that will not heal. Unfortunately, the standard treatment in the United States and Canada does not address the shape of the cleft.

What we do differently, and why you should consider us.

Dr. Immerman performs a procedure called the Bascom procedure, which flattens the cleft, and moves the incision away from the midline so it can heal quickly. This procedure (which is also called “cleft closure” or “cleft lift”) has become his procedure of choice because of his high success rate — even in patients who have had multiple previous excisional procedures. He has had extensive experience with patients who have had chronic open wounds or have open wounds close to the anus.  This procedure is performed as an outpatient under general anesthesia. The pockets of infection are removed and the buttock crease is adjusted. After the operation, the buttock crease will be flatter. This usually heals in a couple of weeks without any packing or special dressings. There is a small drain that is placed and removed in a few days.

Why the cleft-lift is more challenging after previous failed operations

This procedure works best for basic pilonidal disease up on the area around the sacrum. In patients who have had surgery that has failed, the situation can be drastically different for several reasons. One is that extensive tissue removal can interfere with the skin needed for the cleft-lift flap. Also, there are often openings and sinus tracts extending downward toward the anus – outside the area usually treated by the cleft-lift procedure. Most surgeons do not have a strategy for dealing with these wounds other than prolonged local wound care, which may or may not be successful. Dr Immerman has had extensive experience with dealing with these re-operative situations, and often can successfully extend the cleft-lift to treat these very low openings. However, these are the kinds of difficult cases that or rare occasions require a second procedure to get control.

Overall, in Dr Immerman’s hands this procedure has a 97% success rate with one operation. However, as mentioned above there are situations when a second procedure is needed to adjust the anatomy a bit further. Our philosophy is to address these situations as soon as they are recognized, and proceed with a second procedure if necessary. These second procedures have been very successful.
