Application of biofeedback therapy in low anterior rectum resection syndrome

ObjectiveTo investigate the clinical effect of biofeedback therapy (BFT) in low anterior rectal resection syndrome(LARS).

MethodsThe data of 165 patients who met the diagnostic criteria of LARS after laparoscopic low anterior rectal resection were analyzed retrospectively.According to the different treatment methods of LARS, they were divided into BFT group(86 cases) and control group(79 cases).The BFT group received two courses of BFT regularly from the 3rd week after discharge, and the control group received routine symptomatic treatment after operation.The changes of LARS scores before and after treatment were compared between the two groups.

ResultsThere was no significant difference in LARS scores between the two groups at the time of enrollment and after the first course of treatment(P>0.05).After the second course of treatment, the scores of patients in the two groups were lower than those at the time of enrollment(P < 0.05), and the scores in the BFT group were significantly lower than those in the control group(P < 0.01).Two weeks after the end of the second course of treatment, the scores in the two groups were lower than those at the end of first and second courses of treatment(P < 0.05), and the scores in the BFT group were significantly lower than that in the control group(P < 0.01).

ConclusionsBFT can reduce the LARS scores faster than conventional treatment, and accelerate the recovery of LARS patients.
