    Background And ObjectivesStandard treatment of rectal adenocarcinoma located 3-6 cm above anal verge is abdominoperineal resection. The objective was to evaluate feasibility, morbidity, and functional results of anal sphincter preservation after preoperative chemoradiation therapy and coloanal anastomosis in patients with rectal adenocarcinoma located between 3 and 6 cm above the anal verge.MethodsThis study included 17 males and 15 females with a mean age of 54.8 +/- 15.4 years. Tumors were located at a mean of 4.7 +/- 1.1 cm above the anal verge. The mean tumor size was 4.6 +/- 1.5 cm. All patients received the scheduled treatment. Twenty-two patients underwent coloanal anastomosis with the J pouch; 10 underwent straight anastomosis. Average surgical time was 328.7 +/- 43.8 min, and the average intraoperative hemorrhage was 471.5 +/- 363.6 ml. The mean distal surgical margin was 1.3 +/- 0.6 cm. Five patients (15.6%) received a blood transfusion.ResultsMajor complications included coloanal anastomotic leakage (three); pelvic abscess (three), and coloanal stenosis (two). Tumor stages were as follows: T0-2,N0,M0 = 12; T3,N0,M0 = 9; T1-3,N+,M0 = 9, and T1-3,N0-3,M+ = 2. Diverting stomas were closed in 30 patients. Median follow-up was 25 months. Recurrences occurred in four patients and were local and distant (n = 1) and distant (n = 3). Anal sphincter function was perfect (n = 20), incontinent to gas (n = 3), occasional minor leak (n = 2), frequent major soiling (n = 3), and colostomy (n = 2).ConclusionsIn patients with locally advanced rectal cancer located 3-6 cm from anal verge who are traditionally treated with abdominoperineal resection, preservation of anal sphincter after preoperative chemoradiation therapy plus complete rectal excision with coloanal anastomosis is feasible and is associated with acceptable morbidity and no mortality.Copyright 2002 Wiley-Liss, Inc.
