What is a Pilonidal Cyst?

A pilonidal cyst is a round sac of tissue that contains air, fluid, and sometimes hair. These cysts are located in the crease of the buttocks and are caused by a skin infection. The term “pilonidal” means “nest of hair” and is derived from Latin. Pilonidal cysts were first described in 1833 and the condition has been referred to as “Jeep disease” due to its high incidence among soldiers during World War II.

Definition

Pilonidal disease describes a range of clinical presentations, from asymptomatic hair-containing cysts and sinuses to large, symptomatic abscesses in the sacrococcygeal region that tend to recur. A pilonidal cyst can be extremely painful, especially when sitting, and may require treatment.

Formation Process

It is believed that hair penetrates the skin through dilated hair follicles, particularly in late adolescence. Sitting or bending can cause hair follicles to break and open a pit, allowing debris to collect. This can lead to the development of a sinus with a short tract, and further penetration of hair into the subcutaneous tissue due to a suction mechanism. The sinus tends to extend in a cephalad direction due to mechanical forces when sitting or bending.

A foreign body-type reaction may occur, potentially leading to abscess formation. If the abscess drains spontaneously, it can serve as a portal for further invasion and the development of a foreign body granuloma. Infection can also result in abscess formation, and increased sweat may contribute to cyst and sinus development.

Prevalence and Demographics

Pilonidal cysts affect approximately 26 per 100,000 people in the United States. The condition predominantly affects males at a ratio of 3-4:1 compared to females. It is most common in White patients, typically in their late teens to early twenties, with the incidence decreasing after age 25 and rarely occurring after age 45.

Certain factors have been associated with a higher occurrence of pilonidal disease, including:

Local irritation to the sacrococcygeal site (34-50%)
Positive family history of pilonidal disease (34-50%)
Sedentary lifestyle (34-50%)
Obesity (34-50%)

Understanding the definition, formation process, and prevalence of pilonidal cysts is crucial for accurate diagnosis and effective treatment of this condition.

Identifying Pilonidal Cyst Symptoms

The symptoms of a pilonidal cyst can vary from person to person, but there are some common signs to look out for. Early detection and treatment of a pilonidal cyst can help prevent complications and promote faster healing.

Physical Signs

One of the most noticeable signs of a pilonidal cyst is a small dimple or large swollen area between the buttocks. This area may appear red and feel tender to the touch. In some cases, there may be visible pus or blood draining from the cyst, which can have a foul odor. The size of the cyst can vary, ranging from a small pimple-like bump to a large, painful mass.

Associated Discomfort

Pilonidal cysts can cause significant discomfort, especially when sitting for extended periods. The pain may worsen over time and can be accompanied by swelling and inflammation in the affected area. Some individuals may also experience fever, nausea, or extreme fatigue if the cyst becomes infected.

Potential Complications

If left untreated, a pilonidal cyst can lead to serious complications. The cyst may develop into an abscess, which is a pocket of pus that can cause severe pain and swelling. In rare cases, the infection from the cyst can spread to other parts of the body, potentially becoming life-threatening.

It is crucial to seek medical attention if you suspect you have a pilonidal cyst, particularly if you notice any of the following:

Increasing pain or swelling in the affected area
Pus or blood draining from the cyst
Redness or warmth around the cyst
Fever or nausea accompanying the cyst

Your healthcare provider can diagnose a pilonidal cyst through a physical examination and may recommend imaging tests, such as a CT scan or MRI, to determine the extent of the condition. Prompt treatment can help alleviate symptoms, prevent complications, and promote healing.

Treatment Approaches for Pilonidal Cysts

The treatment of pilonidal cysts depends on the severity and extent of the condition. Treatment options range from conservative management to minimally invasive procedures and surgical interventions. The goal of treatment is to alleviate symptoms, promote healing, and prevent recurrence.

Conservative Management

Conservative treatment is often the initial approach for pilonidal cysts, especially in mild cases or when the cyst is not infected. This approach focuses on improving hygiene, reducing inflammation, and promoting drainage. Conservative management may include:

Meticulous hair removal around the affected area
Improved perianal hygiene
Warm sitz baths to promote drainage and reduce discomfort
Antibiotics to treat infection, if present

In a study by Mustafa erman Dorterler and colleagues, conservative treatment was found to be an effective option for pilonidal sinus disease in children. Complete healing occurred in 79.3% of patients, with a recurrence rate of 12%.

Minimally Invasive Procedures

Minimally invasive procedures have gained popularity in recent years as an alternative to traditional surgical interventions. These procedures aim to remove the cyst and its contents while minimizing tissue damage and promoting faster recovery. Some common minimally invasive procedures include:

Fibrin glue administration
Phenol injection
Endoscopic pilonidal sinus treatment (EPSiT)
Video-assisted ablation of pilonidal sinus (VAAPS)

Studies have shown promising results with minimally invasive approaches. For example, Milone et al. demonstrated the feasibility of VAAPS, while Meinero et al. described the effectiveness of EPSiT. These procedures have been associated with shorter operative times, reduced postoperative pain, and high patient satisfaction rates.

Surgical Interventions

In more severe cases or when conservative management and minimally invasive procedures fail, surgical interventions may be necessary. The choice of surgical technique depends on factors such as the extent of the disease, the presence of recurrence, and patient preferences. Common surgical interventions include:

Incision and drainage: This procedure involves making a small incision to drain the cyst and remove any debris or hair. It is often performed under local anesthesia and is suitable for acute, infected cysts.
Excision and primary closure: The cyst and surrounding tissue are surgically removed, and the wound is closed with sutures. This approach has a lower recurrence rate compared to incision and drainage but may be associated with longer healing times and a higher risk of wound complications.
Excision with open healing: After removing the cyst and affected tissue, the wound is left open to heal by secondary intention. This method reduces the risk of wound complications but may require longer healing times.
Flap procedures: In complex cases or recurrent pilonidal disease, flap procedures such as the Karydakis flap or Bascom cleft lift may be performed. These techniques involve reshaping the natal cleft to reduce friction and promote better healing.

The choice of surgical intervention should be individualized based on the patient’s specific needs and the surgeon’s expertise. Postoperative care, including wound management and hair removal, is crucial to minimize the risk of recurrence.

In conclusion, the treatment of pilonidal cysts encompasses a spectrum of approaches, from conservative management to minimally invasive procedures and surgical interventions. The optimal treatment strategy depends on the severity of the condition, patient factors, and the goals of treatment. A multidisciplinary approach involving patient education, meticulous hygiene, and appropriate medical and surgical interventions can lead to successful outcomes and improved quality of life for individuals affected by pilonidal cysts.

Conclusion

Pilonidal cysts, while often painful and uncomfortable, can be effectively managed with the right approach. This guide has shed light on the causes, symptoms, and treatment options available to those dealing with this condition. By understanding the signs and seeking timely medical attention, individuals can minimize discomfort and prevent potential complications.
