Pilonidal Sinus—Plenty of Literature yet Lack of Direction: A Pooled Analysis

Abstract

A systematic analysis was conducted to compare various surgical treatment modalities and evaluate the short- and long-term outcomes in the management of sacrococcygeal pilonidal disease. Pilonidal sinus is a common and debilitating condition often requiring a surgical approach to treatment, of which many are available. Despite numerous treatment methods, no universal decision has been made as to the most efficient and effective surgical treatment. All randomized control trials published between January 1, 2003 and January 8, 2013 were accessed. Interventions included classic and modified Limberg flap, Karydakis flap, primary closure, and healing by secondary intention. Primary outcome measures included rate of surgical site infection, recurrence, and length of hospital stay. Secondary outcome measures were hematoma or seroma, and return to work. The search identified 22 articles suitable for inclusion in this review totaling 3693 patients. Analysis showed a 50% reduction in the rate of infection and recurrence in patients receiving closure with flaps compared with primary midline closure and healing by secondary intention. The Karydakis flap was shown to be more favorable cosmetically; however, it failed to compete with the classic and modified Limberg flap in treatment of complicated disease. No significant difference was noted between the modified Limberg and Limberg flap. These results show that the Karydakis flap, classic, and modified Limberg flap demonstrate significant benefits over healing by secondary intention and primary closure.
