title: Management of Radiation Anterior Prostato-symphyseal Fistulas With Interposition Rectus Abdominis Muscle Flap.
abstract: OBJECTIVE
  To describe a novel, organ-sparing approach for reconstruction of radiation-induced anterior prostato-symphyseal fistulas (PSFs) at our institution over a consecutive 10-year period.
  
  
  METHODS
  We performed a retrospective review of patients undergoing surgical reconstruction for anterior PSF between January 1, 2006 and October 31, 2015. Patient demographics as well as preoperative, operative, and postoperative data were reviewed, including etiology of fistula, surgical management, and outcomes.
  
  
  RESULTS
  A total of 4 patients with anterior PSF underwent organ-sparing reconstruction. All fistulas were the result of previous pelvic radiation. All 4 patients presented with pubic osteomyelitis. Patients underwent pubic symphysis debridement, fistula closure, and placement of an interposition rectus abdominis muscle flap. At a median follow-up of 27 months, 100% of the patients undergoing repair with interposition rectus flap were closed with 1 procedure.
  
  
  CONCLUSIONS
  Radiation-induced PSF can be successfully reconstructed with pubic symphysis debridement and fistula closure using an adjunct rectus abdominis interposition flap, avoiding prostatectomy and urinary diversion.
