Aim: The aim of this study was to evaluate whether the long duration of defunctioning stoma was associated with increased rates of coloanal anastomosis stenosis. Method: Medical records of all adult patients diagnosed with rectal cancer and who underwent low anterior resection and defunctioning stoma at two centres were retrospectively analysed. All patients underwent colonoscopy to evaluate the coloanal anastomosis state. The primary outcomes of this study were evaluation of the rate of anastomotic stenosis and comparison of the durations between patients with anastomotic stenosis and those without stenosis. Results: Between April 2009 and December 2017, 72 patients with rectal cancer underwent resection with defunctioning stoma at two centres, and 69 of them were included in this study. The median patient age was 65 (28-92) years. Defunctioning ileostomy was performed in 50 (73%) patients, whereas defunctioning colostomy was performed in 19 (27%) patients. The median stoma duration of the patients with anastomotic stenosis (n=19) was significantly longer than that of patients without stenosis (n=50) [at 15 (7-41) and 7 (2-25) months, respectively, p=0.002]. Conclusion: This study showed that a long duration of defunctioning stoma was associated with increased rates of coloanal anastomosis stenosis.
