Pelvic floor imaging in asymptomatic subjects.

AIM: The aim of this work was to determine the range of normal imaging features during total pelvic floor ultrasound (TPFUS) (transperineal, transvaginal, endovaginal and endoanal) and defaecation MRI (dMRI). METHOD: Twenty asymptomatic female volunteers (mean age 36.5 years) were prospectively investigated with dMRI and TPFUS. Subjects were screened with symptom questionnaires (ICIQ-B, St Mark's faecal incontinence score, obstructed defaecation syndrome score, ICIQ-V, BSAQ). dMRI and TPFUS were performed and interpreted by blinded clinicians according to previously published methods. RESULTS: The subjects comprised six parous and 14 nulliparous women, of whom three were postmenopausal. There were three with a rectocoele on both modalities and one with a rectocoele on dMRI only. There was one with intussusception on TPFUS. Two had an enterocoele on both modalities and one on TPFUS only. There were six with a cystocoele on both modalities, one on dMRI only and one on TPFUS only. On dMRI, there were 12 with functional features. Four also displayed functional features on TPFUS. Two displayed functional features on TPFUS only. CONCLUSION: This study demonstrates the presence of abnormal findings on dMRI and TPFUS without symptoms. There was a high rate of functional features on dMRI. This series is not large enough to redefine normal parameters but is helpful for appreciating the wide range of findings seen in health.

Improving Multidisciplinary Team Working to Support Integrated Care for People with Frailty Amidst the COVID-19 Pandemic.

Multidisciplinary team (MDT) working is essential to optimise and integrate services for people who are frail. MDTs require collaboration. Many health and social care professionals have not received formal training in collaborative working. This study investigated MDT training designed to help participants deliver integrated care for frail individuals during the Covid-19 pandemic. Researchers utilised a semi-structured analytical framework to support observations of the training sessions and analyse the results of two surveys designed to assess the training process and its impact on participants knowledge and skills. 115 participants from 5 Primary Care Networks in London attended the training. Trainers utilised a video of a patient pathway, encouraged discussion of it, and demonstrated the use of evidence-based tools for patient needs assessment and care planning. Participants were encouraged to critique the patient pathway, reflect on their own experiences of planning and providing patient care. 38% of participants completed a pre-training survey, 47% a post-training survey. Significant improvement in knowledge and skills were reported including understanding roles in contributing to MDT working, confidence to speak in MDT meetings, using a range of evidence-based clinical tools for comprehensive assessment and care planning. Greater levels of autonomy, resilience, and support for MDT working were reported. Training proved effective; it could be scaled up and adopted to other settings.

Pelvic floor investigations for anal incontinence: Are they useful to predict outcomes from conservative treatment?

AIMS: There are several options for treating anal incontinence (AI), with limited success rate in long-term follow-up. Patients' selection is important to avoid unnecessary investigations and therapies. The aim of this review is to assess the utility of pelvic floor investigations to predict success from conservative treatment in AI. METHODS: Baseline demographics, severity scores, and pelvic floor investigations of 490 patients with AI symptoms were retrospectively reviewed. Patient-reported outcomes were used to define success of conservative treatment. RESULTS: Bivariate analysis showed that gender, St Mark's incontinence score, Bowel continence and quality of life domains of International Consultation on Incontinence Modular Questionnaire-Bowel symptoms score, Bristol stool chart, anal squeeze pressure, enterocoele, leak of contrast at rest, and dyssynergia in defecography were associated with patient's outcomes from conservative treatment (p < 0.05). Multivariate analysis showed that only the Bowel continence score was an independent predictor of patient's success with treatment. CONCLUSIONS: Pelvic floor investigations are of limited value to predict success of conservative treatment and they should be reserved for patients who fail noninvasive management and might require surgical intervention.

The association between levator plate integrity and pelvic floor defaecatory dysfunction.

AIMS: Levator ani deficiency has been implicated in anterior pelvic floor pathology but its association with pelvic floor defaecatory dysfunction is less clear. The aim was to examine the relationship of levator ani deficiency with anatomical abnormalities (rectocoele, intussusception, enterocoele, perineal descent) and patient symptoms (bowel, vagina) in patients with pelvic floor defaecatory dysfunction. METHODS: The prospective observational case series of 223 women presenting to a tertiary colorectal pelvic floor unit with defaecatory dysfunction. Each underwent assessment with symptom severity and quality of life (QoL) scores, integrated total pelvic floor ultrasound (PFUS) (transvaginal, transperineal) and defaecation proctography (DP). Rectocoele, intussusception, enterocoele and perineal descent were assessed on both. Levator ani deficiency was scored using endovaginal ultrasound (score 0-18; mild [0-6], moderate [>6-12], severe [>12-18]). RESULTS: The proportion of patients with rectocoele, enterocoele, and intussusception increased with increasing levator ani damage (mild, moderate, severe). There was a weakly positive correlation between size of rectocoele and levator ani deficiency. On PFUS, there was a weakly positive correlation between severity of intussusception and enterocoele with levator ani deficiency. On DP, there was a weakly positive correlation between perineal descent and levator ani deficiency. There was no association between bowel symptom and QoL scores and levator ani deficiency. Vaginal symptoms were associated with levator ani deficiency. CONCLUSIONS: Anatomical abnormalities which are implicated in pelvic floor defaecatory dysfunction (rectocoele, intussusception, enterocoele, perineal descent) were associated with worsening levator ani deficiency. There was no association between bowel symptoms and levator ani deficiency. Vaginal symptoms were associated with levator ani deficiency.

Total pelvic floor ultrasound can reliably predict long-term treatment outcomes for patients with pelvic floor defaecatory dysfunction.

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.

Patient pathway in a tertiary referral pelvic floor unit: Telephone triage assessment clinic.

BACKGROUND: To meet the increasing demands for colorectal pelvic floor services, a dedicated telephone triage assessment clinic (TTAC) was set up to establish a more efficient pathway, and reduce waiting times and patient's visits to the hospital. The primary aim of this study was to review TTAC in patients suffering from pelvic floor dysfunction and assess its feasibility. Secondary aims include measurement of waiting times for TTAC, main presenting complaints, and main treatment outcomes, including the need for review by a consultant surgeon. METHODS: Review of data collected retrospectively in a single tertiary referral center collected from an institutional database. KEY RESULTS: Between January 2016 and October 2017, 1192 patients referred to our pelvic floor unit were suitable for TTAC. Of these, 694 patients had complete records. There were 66 without follow-up after the initial TTAC, leaving 628 patients for analysis. In all, 86% were females and 14% were males, with a mean age of 52 years (range: 18-89). The median waiting time for TTAC was 31 days (range: 0-184). The main presenting complaint during the TTAC was obstructive defecation in 69.4%, fecal incontinence in 28.5%, and rectal prolapse in 2.1%. In our study, 611 patients had conservative management (97.3%), with a median of three sessions per patient (range: 1-16), while 82 patients (13.1%) needed a surgical intervention. Only 223 patients (35.5%) were reviewed by a consultant at some stage during the study period. CONCLUSIONS AND INFERENCES: To optimize resources, an adequate triage system allowed us to streamline the pathway for each individual patient with pelvic floor dysfunction according to their symptoms and/or test results with the aim of reducing waiting times and expediting treatment.

Is there any association between symptoms and findings on imaging in pelvic floor defaecatory dysfunction? A prospective study.

AIM: To compare features on imaging (integrated total pelvic floor ultrasound (transperineal, transvaginal) and defaecation proctography) with bowel, bladder and vaginal symptoms in pelvic floor defaecatory dysfunction. METHOD: A prospective observational case series of 216 symptomatic women who underwent symptom severity scoring (bowel, bladder and vaginal), integrated total pelvic floor ultrasound and defaecation proctography. Anatomical (rectocele, intussusception, enterocele, cystocele) and functional (co-ordination, evacuation) features were examined. RESULTS: Irrespective of imaging modality, patients with a rectocele had higher International Consultation on Incontinence Modular Questionnaire - Vaginal Symptoms (ICIQ-VS) scores than patients without. On integrated total pelvic floor ultrasound, ICIQ-VS quality of life scores were higher in those with a rectocele. There was a higher International Consultation on Incontinence Modular Questionnaire - Bowel Symptoms (ICIQ-BS) bowel pattern score in those with a rectocele, and a lower ICIQ-BS bowel pattern and sexual impact score in those with intussusception. Poor co-ordination was associated with increased ICIQ-BS bowel control scores and obstructed defaecation symptom scores. On defaecation proctography, ICIQ-VS symptom scores were lower in patients with poor co-ordination. CONCLUSION: Patients with a rectocele on either imaging modality may have qualitative vaginal symptoms on assessment. In patients with bowel symptoms but no vaginal symptoms, it is not possible to predict which anatomical abnormalities will be present on imaging.

Total pelvic floor ultrasound for pelvic floor defaecatory dysfunction: a pictorial review.

Total pelvic floor ultrasound is used for the dynamic assessment of pelvic floor dysfunction and allows multicompartmental anatomical and functional assessment. Pelvic floor dysfunction includes defaecatory, urinary and sexual dysfunction, pelvic organ prolapse and pain. It is common, increasingly recognized and associated with increasing age and multiparity. Other options for assessment include defaecation proctography and defaecation MRI. Total pelvic floor ultrasound is a cheap, safe, imaging tool, which may be performed as a first-line investigation in outpatients. It allows dynamic assessment of the entire pelvic floor, essential for treatment planning for females who often have multiple diagnoses where treatment should address all aspects of dysfunction to yield optimal results. Transvaginal scanning using a rotating single crystal probe provides sagittal views of bladder neck support anteriorly. Posterior transvaginal ultrasound may reveal rectocoele, enterocoele or intussusception whilst bearing down. The vaginal probe is also used to acquire a 360° cross-sectional image to allow anatomical visualization of the pelvic floor and provides information regarding levator plate integrity and pelvic organ alignment. Dynamic transperineal ultrasound using a conventional curved array probe provides a global view of the anterior, middle and posterior compartments and may show cystocoele, enterocoele, sigmoidocoele or rectocoele. This pictorial review provides an atlas of normal and pathological images required for global pelvic floor assessment in females presenting with defaecatory dysfunction. Total pelvic floor ultrasound may be used with complementary endoanal ultrasound to assess the sphincter complex, but this is beyond the scope of this review.
