Lower recurrence rate for Limberg vs. V-Y flap for pilonidal sinus.

Abstract

Pilonidal sinus is a disease that does not have a standardized surgical treatment method. This study was designed to compare the outcomes of Limberg fasciocutaneous transposition and V-Y fasciocutaneous advancement flaps in the treatment of patients with pilonidal sinus. A total of 111 patients (98 males; 88.3 percent; mean age, 27.1 years) who received reconstruction after pilonidal sinus excision in our clinics with Limberg flap (Group 1, n = 66, 59.5 percent) or V-Y flaps (Group 2, n = 45, 40.5 percent) between 1997 and 2004 were investigated retrospectively. No significant difference was detected between Groups 1 and 2 in terms of gender, history of infection or abscess, mean duration of operation, requirement for analgesics, wound-related complications, such as necrosis, seroma, and infection, and average time off work. Mean follow-up periods were 45.4 vs. 48.8 months in Group 1 and Group 2, respectively (P = 0.337). On the other hand, rate of recurrence was significantly lower in Group 1 (n = 1, 1.5 percent) compared with Group 2 (n = 5, 11.1 percent; P = 0.039). We conclude that, if the defect is to be reconstructed with a flap in pilonidal sinus cases, reconstruction with Limberg flap should be preferred over reconstruction with V-Y flap because of its lower rate of recurrence.
