Factors influencing changing bowel habits in patients undergoing sphincter-saving surgery for rectal cancer

Abstract

A research survey research was conducted to identify factors affecting changes in bowel habits of rectal cancer patients undergoing sphincter-saving surgery and to provide basic information useful in nursing interventions supporting treatment for rectal cancer patients. The subjects were rectal cancer patients who had undergone sphincter-saving surgery over 2 years ago. The final analysis included 107 patients who had made outpatient visits to the colorectal surgery from 12th to 31st May, 2014. Collected data were processed with SPSS Version 21.0. Changes in bowel habits in the subjects were observed: frequent bowel movement in 74 patients (69.2%) and faecal incontinence in 48 (44.9%). Most of the patients used self-care to improve their bowel function including dietary modification (78.5%), regular exercise (72.0%) and pelvic floor exercise (34.6%). Frequent defecation was associated with adjuvant chemoradiation therapy (P < 0.001) and faecal incontinence was associated with age of ≥65 years (P = 0.019) and a group who underwent adjuvant radiation therapy (P < 0.001). It is necessary to give sufficient information about possible postoperative changes in bowel habits to patients with the risk factors before surgery.
