ABSTRACT
INTRODUCTION AND OBJECTIVE:
Transanal endoscopic microsurgery (TEM) is a new technique for local excision of benign and incipient malignant rectal lesions. This technique offers technological advantages over other procedures and is associated with lower morbidity and mortality. TEM involves prolonged dilatation of the anal sphincter with a large-diameter (4 cm) operating rectoscope. The aim of the present study was to assess the effects of TEM on anorectal function. MATERIAL ANDMETHODS:
All patients undergoing TEM were included. Continence was scored by a numeric scale and anorectal manometry before surgery and 3 weeks and 4 months after surgery. Variations in anal resting pressure, maximal anal resting pressure and the anal continence questionnaire were evaluated.RESULTS:
Sixty-eight patients underwent TEM between June 2004 and August 2006. Mean anal resting pressure (ARP) and maximal anal resting pressure (MARP) were significantly reduced at 3 weeks after surgery (ARP/MARP before surgery 38.89/126.28; 3 weeks after surgery 26.61/104.75). No significant change was found in the mean continence score. No association was found between variation in pressures and operating time.CONCLUSION:
TEM produced statistically significant alterations in anorectal physiology studies which returned to normal at 4 months. The technique did not affect continence scores in the immediate or late postoperative period and consequently can be considered a safe procedure that does not produce significant alterations in anorectal function.
