Graciloplasty for the rectovaginal fistula after chemoradiation followed by total mesorectal excision for rectal cancer

摘要

Rectovaginal fistula (RVF) is one of the intractable complications following chemoradiation and total mesorectal excision (TME) for rectal cancer. It is supposed that there is a strong possibility of this complication occurring in patients after radiation therapy and having underlying sepsis. We describe herein two female patients (73 and 40 years old) who developed RVF after chemoradiation and TME for rectal cancer, who were successfully managed by gracilis muscle transposition. Fecal diversion was done as a preliminary step to the fistula repair. Success was defined as healed fistula after stoma closure. The strategy in the present report is a useful option for RVF management in such patients as other successful modalities are very limited.
