Patients are predominantly female with symptoms of obstructed defaecation syndrome, where individuals have difficulty in emptying their bowels. Defaecation proctography provides dynamic imaging of the pelvic floor to assess the anatomy and dynamics of defaecation. It can provide considerable weight to clinical decision-making, such as whether surgery or conservative therapy would be more appropriate.

Obstructed defecation symptoms (ODS) include prolonged straining to make a bowel movement and inability or manual assistance required to fully empty the rectum (Elshazly et al. 2010; Rojas et al. 2016; Rostaminia et al. 2020). ODS can be categorized into two types: 1) abdominal constipation with hard stool or infrequent bowel movement—defined as less than 3 times per week—and 2) pelvic constipation (Wingate et al. 2002; D’Hoore and Penninckx 2003). ODS are common, affecting approximately 7% of all adults, but 15-20% of adult women (Elshazly et al. 2010; Podzemny et al. 2015; Rostaminia et al. 2019). Although its etiology is still debated, it is hypothesized that the higher prevalence observed in women could be due to damage incurred by pelvic floor soft tissues and nerves during vaginal delivery (Ellis and Essani 2012).
