A review on functional results of sphincter-saving surgery for rectal cancer: the anterior resection syndrome

摘要: The aim of this review is to characterize the functional results and “anterior resection syndrome” (ARS) after sphincter-saving surgery for rectal cancer. purpose operations save anal sphincters by avoiding need abdomino-perineal with a permanent stoma. A variety alternative techniques have been proposed and, today, ultra-low anterior resections rectum are commonplace. Inevitably modify anorectal physiology. backdrop asset ultralow related small neorectal capacity high endo-neorectal pressures that act together on weakened sphincteric mechanism. Sometimes defecation disorder called ARS may be induced patient experiences an extremely low quality life. Impaired bowel function usually provoked either colonic dysmotility, reservoir dysfunction, sphincter damage or combination these factors. Surgical technique defects can contribute possible causes: anastomotic ischemia, short length descending colon stretching mesentery play role. Unfortunately, there no therapeutic algorithm gold standard treatment used ARS. Nevertheless, it rational use conservative therapy first then resort surgery. Drugs, rehabilitative sacral neuromodulation used; failure methods, surgical considered.
