The application of the Limberg flap repair technique in the surgical treatment of pilonidal sinus disease. [PDF]
Abstract Pilonidal sinus disease (PNSD) challenged surgeons for decades. Limberg flap repair (LFR) is a common treatment for PNSD. The purpose of this study was to observe the effect and risk factors of LFR in PNSD. A retrospective study was conducted on the PNSD patients who visited two medical centers and four departments in the People's Liberation ...
