Biofeedback therapy for symptoms of bowel dysfunction following surgery for colorectal cancer

Abstract

The holistic biofeedback protocol for PSBD in CRC patients is successful in the short and medium term.

Pelvic floor muscle training for bowel dysfunction following colorectal cancer surgery: A systematic review

“…In contrast to the beneficial effects of PFMT on the patientreported measures of bowel function, all studies except one retrospective study reported no significant changes in manometric measures following interventions. 32,33,36,37,39 The inconsistent findings between patient-reported measures and objective manometric measures of bowel function were consistent with previous studies, which demonstrated no correlation between anorectal manometry and severity of fecal incontinence 41,42 or patients' perception of relief. 43 This may be due to the multifactorial etiology of bowel dysfunction or insufficient intensity of PFMT to achieve a physiological effect.…”

“…Study results on patient‐reported measures of bowel function are presented in Table . Six studies showed improvement in stool frequency after intervention, and four were statistically significant ( P < 0.05) . Liu et al reported no significant differences in stool frequency between intervention and control groups after home‐based PFMT .…”

“…In the study by Allgayer et al, the MCIS significantly increased ( P < 0.001) indicating improved incontinence in 95 participants after a 3‐week intensive PFMT . The results of studies using WIS also showed a significant improvement in severity of fecal incontinence after intervention ( P < 0.05), except for Laforest et al, who reported no significant difference in WIS score between intervention and control groups . Two studies demonstrated conflicting long‐term follow‐up results of severity of fecal incontinence .…”

“…Of the three studies that assessed incontinence episodes, two showed a significant decrease in incontinence episodes ( P < 0.05) after PFMT using manometric biofeedback . Bartlett et al reported no significant difference in incontinence episodes after PFMT using manometric pressure biofeedback …”

“…The results of studies using WIS also showed a significant improvement in severity of fecal incontinence after intervention ( P < 0.05), except for Laforest et al, who reported no significant difference in WIS score between intervention and control groups . Two studies demonstrated conflicting long‐term follow‐up results of severity of fecal incontinence . One study reported maintenance of effects of PFMT with intra‐anal EMG biofeedback after 1 year, and the other study reported increased severity at 2 years following last treatment session of PFMT using manometric biofeedback, although the severity remained better than at baseline …”
