Aim: Integrated total pelvic floor ultrasound (TPFUS) may provide an alternative to defaecation proctography (DP) in decision making and treatment planning for patients with pelvic floor defaecatory dysfunction (PFDD). This study evaluates the use of TPUS as a screening tool, and its likelihood to predict long-term treatment outcomes.
Methods: Two blinded clinicians reviewed 100 women who had historically presented to a tertiary referral colorectal unit with PFDD from October 2014 to April 2015. The clinical history of the patients together with TPFUS or DP results were used to decide on main impression, treatment plan, likelihood of surgery and certainty of plan. These were compared to the actual treatment received six months later and again after a median follow-up of 68 months (range 48-84).
Results: A total of 82 patients were treated with biofeedback only and 18 also underwent surgery. There were no complications in any of the patients who had surgery. When compared with the actual treatment received, 99 of the 100 of the TPFUS group would have been treated appropriately. The number of false positives for surgical treatment was lower with TPFUS compared to DP. Clinician confidence in the overall decision was significantly higher after review with DP.
Conclusions: TPFUS is a reliable assessment tool for PFDD. It can identify patients who can go straight to biofeedback and is just as good as DP at predicting likelihood of surgery. We might be able to rely on TPFUS more significantly in the future, even for surgical planning.
