Graciloplasty for Internal and External Sphincteric Resection of Lower Rectal Cancer

Anal sphincteric resection for rectal cancer is most commonly followed by colostomy in the lower abdominal wall, which enforces quite a poor quality of life due to a permanent stoma. For surgeons treating lower rectal cancer, the goal is to achieve defecation via the anus without placing a stoma. Internal sphincteric resection, partial external sphincteric resection and coloanal anastomosis have been reported for the treatment of lower rectal cancer with avoiding a colostoma. Extended resection of the external sphincter, however, limits patient's daily activities because of poor functional results and necessitates reconstruction of damaged anal function. This paper describes a case of graciloplasty for postoperative anal dysfunction that yielded a good clinical outcome in a 65-year-old female who had undergone very low anterior resection with complete internal and partial external sphincteric resection for lower rectal cancer.
