Effect of biofeedback training on bowel function among patients undergoing rectal cancer anus preserving operation

Abstract

Objective To evaluate the effect of biofeedback on bowel function among rectal cancer patients with chemoradiotherapy and temporary enterostomy. Methods This study was designed as a randomized controlled trial. The patients with low and middle rectal cancer in a Cancer Hospital of Guangzhou from June 2015 to December 2016 were randomly divided into pelvic floor muscle exercise group (control group, n=36) and biofeedback training group (intervention group, n=35) . The intestinal function questionnaire of the Chinese version of Memorial Sloan-Kettering Cancer Center (MSKCC) was used to longitudinally track and compare the intestinal function of the two groups for 16 months and 5 times in total. Results The total score of MSKCC, frequency and urgency of defecation and defecation sensory disturbance in intervention group were higher than those in control group at 4 days and 3 months after stoma inclusion operation, and the differences were statistically significant (P<0.05) . Conclusions Biofeedback training can improve the intestinal function of patients with middle and low rectal cancer, promote their recovery, and prevent intestinal and anal dysfunction of patients with middle and low rectal cancer.
