About

In this study, we aim to compare the Karydakis flap and Burow's Triangle Advancement Flap techniques applied in the surgical treatment of pilonidal sinus in terms of complications, time to return to normal activity, and recurrence.

Full description

Pilonidal sinus disease (PSD) is a chronic and inflammatory disease that is often generated in the sacrococcygeal region. It is commonly observed in puberty and young adult period and usually affects men. The incidence of pilonidal sinus disease is 26:100,000 and rising globally.

PSD risk factors contain young age, obesity, male gender, Mediterranean ethnicity, deep natal cleft, hairiness, and poor hygiene. It has been shown that PSD incidence increases in parallel with body weight. The precise etiology of pilonidal sinus disease is unclear. Many conservative and surgical methods have been described in treating pilonidal sinus disease. After the sinus area is excised, excision with laying open (secondary healing), excision with primary closure, marsupialization, and various flap techniques can be applied in surgical treatment. The primary principle in treatment is to ensure that the patient returns to normal life as soon as possible and eliminate recurrences. Although the best surgical technique in treating pilonidal sinus is controversial, the ideal operation should be cost-effective, simple to perform, short hospital stay, and have a low recurrence and complication rates. There is no definite consensus on an ideal technique yet.

In this study, we aim to compare the Karydakis flap and Burow's Triangle Advancement Flap techniques applied in the surgical treatment of pilonidal sinus in our clinic in terms of complications (wound dehiscence, seroma, hematoma, surgical site infection), time to return to normal activity, and recurrence.

80 participants in 2 patient groups

Karydakis Flap Procedure

Active Comparator group

Description:

Vertical eccentric elliptical incision down to the post-sacral fascia, complete removal of unhealthy tissue, and normal tissue around the cyst and sinus tracts. Mobilization of the medial wound edge and advancement of the skin. Flap along the midline to the post-sacral fascia and suturing its margin to the lateral wound margin.

Treatment:

Procedure: Karydakis Flap Procedure

Burow's Triangle Advancement Flap Procedure

Active Comparator group

Description:

The flap is incised along the base of the wedge-shaped defect, and a small Burow's triangle is excised on the opposite side. The skin is mobilized and shifted in the direction of the arrow to close the defect. Excising the small Burow's triangle eliminates a dog ear at the base of the flap.

Treatment:

Procedure: Burow's Triangle Advancement Flap Procedure
