Abstract

Abstract : OBJECTIVES: : Dyssynergic defecation (DD) is a subtype of chronic constipation that responds to biofeedback therapy (BFT). Abdominal, anorectal, and stool symptoms are commonly reported by DD patients, but limited data exist to demonstrate the improvement of these associated symptoms to BFT. Aims to prospectively study the response of constipation and associated abdominal, rectal, and stool symptoms to biofeedback in a population with dyssynergia. METHODS: : Patients with DD as determined by anorectal manometry and balloon expulsion testing were included into the study. All patients completed a validated survey, the Personal Assessment of Constipation Symptom (PAC‐SYM) questionnaire, before and following BFT. The PAC‐SYM is a clinical tool to assess constipation‐related symptom frequency and severity. RESULTS: : Seventy‐seven dyssynergic patients fulfilled the study requirements. Abdominal symptoms were present in up to 74% of patients with dyssynergia. PAC‐SYM summation scores improved following completion of biofeedback by 48%, from 22.08 to 11.48 ( P <0.001). The proportion of patients with at least moderate symptoms decreased in all 12 questionnaire items, including all abdominal symptoms, after completing BFT (46.8% to 14.3%, P <0.001). CONCLUSIONS: : Abdominal symptoms are common in patients with dyssynergia. BFT improves both anorectal‐related constipation symptoms and associated abdominal symptoms in patients with DD. Limitations of this study are observational design, lack of control group, and lack of long‐term follow‐up.
