Introduction: The aim of the study was to assess the functional results after anterior resection (AR) and low anterior resection (LAR) in patients operated on for rectal cancer. Material and methods: The study group consisted of 55 patients (24 women and 31 men, mean age of 61.9±10.1). The group of 32 patients underwent AR (anastomosis >6 cm from anal verge) and the group of 23 patients underwent LAR (anastomosis <6 cm). After 12 months all studied patients were followed-up. Survey consisted of two parts: first part related to anorectal function, second part concerned sexual disturbances. Anorectal manometry was performed during follow-up study. Results: All values of anorectal pressures decreased after operation. However in follow-up study no significant differences in anorectal manometric findings between AR and LAR patients were noted. Problems with erection were quite often in all the group of men, it concerned 10 patients (32.3%). Problems with ejaculation concerned 13 male patients (41.9%). Urgency affected patients after LAR significantly more often than patients after AR: 47.8% vs. 9.4%; p=0.017, respectively. Soiling was also more frequent in LAR than in AR group: 43.5% vs. 9.4%; p=0.031. Conclusions: Surgery for rectal cancer can deteriorate sphincters’ function in a high proportion of patients irrespective of type of the procedure. Soiling and urgency are significantly more severe in patients with lower colorectal anastomosis. Sexual dysfunctions are very common complaints either in women or in men following total mesorectal excision. (Clin Exp Med Lett 2009; 50(3):193-196)
