Abstract
BACKGROUND: The aim of the study was to evaluate the clinical usefulness of anorectal manometry (AM) in patients affected by obstructed defecation (OD). METHODS: Between January 2007 and December 2010, 379 patients (287 women and 92 men) affected by OD were evaluated. After a preliminary clinical evaluation, defecography and AM were performed. The results were compared with those from 20 healthy control subjects. RESULTS: Overall anal resting pressure was not significantly different between patients and controls. Maximal voluntary contraction (MVC) data were significantly lower when compared with those of controls (P < 0.01). The straining test was considered positive in 143 patients. No significant difference was noted between patients and controls in maximal tolerated volume data. Patients had a significantly higher conscious rectal sensitivity threshold than controls (P < 0.02). CONCLUSIONS: A positive straining test, low MVC and impaired rectal sensation are the main abnormalities detected by AM in patients with OD.
