Abstract
Abstract
Introduction In recent years, a standardized surgical approach for low rectal cancer was proposed and adopted in many centres. The extralevator abdominoperineal excision introduce an extensive resection of the pelvic floor and demonstrated superiority if the procedure is done in the prone jack-knife position, especially regarding intraoperative perforation and circumferential resections margins. The aim of this study is to evaluate the surgical and oncological short-term outcomes of prone extralevator abdominoperineal excision.
Methods All patients registered in our institution from January 2003 to January 2015 who underwent abdominoperineal resection or prone extralevator abdominoperineal excision for low rectal cancer after preoperative chemoradiation were retrospectively included from prospective maintained data base and were compared regarding surgical and oncological outcomes.
Results Eighty-nine patients underwent curative intent resections. Abdominoperineal resection was performed in 67 patients and prone extralevator abdominoperineal excision in 22 patients. There were no statistical significant differences between groups regarding pathological stage, median number of harvested lymph node, intraoperative perforation, circumferential resections margins involvement and recurrence rates. Surgical outcomes were statistically different between groups. Twenty-six patients (29%) developed perineal complications, 21% of the abdominoperineal resection patients and 55% of the prone extralevator abdominoperineal excision (p < 0.001). Most of these complications were due to delayed perineal wound healing (12.4%), and wound abscesses (4.5%). However, the readmission rate and median length of hospital stay was higher in the abdominoperineal resection group (p < 0.001).
Conclusion Prone extralevator abdominoperineal excision is comparable to standard abdominoperineal resection. It was associated to a decrease in length of hospital stay and readmission rate, although more perineal complications occurred. We cannot recommend it as a standard technique for all low rectal cancer. Notwithstanding, prone extralevator abdominoperineal excision can be considered a more radical approach when there is sphincter complex or levators muscles invasion.
