A longitudinal vaginal septum is a rare congenital anomaly that can cause dyspareunia, difficulty with tampon insertion, persistent vaginal bleeding and dysmenorrhea. Various surgical techniques have been described.We present a 14 year old female with obesity and diabetes mellitus with uterine didelphys and double vagina with a longitudinal vaginal septum. The patient presented with dysmenorrhea. Resection of the longitudinal vaginal septum utilizing a GIA and EndoGIA (Medtronic, Inc, Doral Fl) stapler device was performed.We introduce a safe and effective technique for resecting a longitudinal vaginal septum utilizing stapler technology. This technique eliminates the potential risk of thermal injury to nearby structures from currently described methods.
