Outcomes of Robotic Partial Excision of the Levator Ani Muscle for Locally Advanced Low Rectal Cancer Invading the Ipsilateral Pelvic Floor at the Anorectal Ring Level

xlomafota13 shared this article with you from Inoreader Outcomes of Robotic Partial Excision of the Levator Ani Muscle for Locally Advanced Low Rectal Cancer Invading the Ipsilateral Pelvic Floor at the Anorectal Ring Level Via The International Journal of Medical Robotics and Computer Assisted Surgery Abstract Purpose The purpose of this study is to evaluate partial excision of the levator ani muscle (PELM) enables preservation of anal sphincter function although levator ani muscle (LAM) was invaded. Methods Functional outcomes and oncologic outcomes of 23 consecutive patients who underwent robotic PELM for low rectal cancer at the anorectal ring level invading or abutting the ipsilateral LAM are analyzed. Results Secured resection margins were achieved, especially for the circumferential resection margin. During a median follow-up of 44 months, the 3-year local recurrence rate was 14.4%. Among patients who underwent diverting ileostomy closure, mean Memorial Sloan Kettering Cancer Center Bowel Function Instrument and Wexner scores were 68.3±11.9 and 10.7±5.3, respectively, at 1 year after closure. Conclusion PELM is a sphincter-preserving alternative to APR or extralevator APR for low rectal cancer invading the ipsilateral LAM at the level of the anorectal ring.
