“…2,3 Further introduction of three-dimensional (3D) volume imaging has enabled accurate diagnostic evaluation of the full extent of the anal sphincter defect. 4 However, some patients find EAU embarrassing, the equipment is not universally available, and it requires a trained operator. Furthermore, the internal probe may cause disruption of the normal anatomy of the anal sphincter.…”

AIM: To determine the accuracy and predictive value of transperineal (TPU) and endovaginal ultrasound (EVU) in the detection of anal sphincter defects in women with obstetric anal sphincter injuries and/or postpartum symptoms of faecal incontinence.MATERIALS AND METHODS: One hundred and sixty-five women were recruited, four women were excluded as they were seen years after their last delivery. TPU and EVU, followed by endonanal ultrasound (EAU), were performed using the B&K Viking 2400 scanner. Sensitivity and specificity, as well as predictive values with 95% confidence intervals, for detecting anal sphincter defects were calculated for EVU and TPU, using EAU as the reference standard.RESULTS: On EAU a defect was found in 42 (26%) women: 39 (93%) had an external (EAS) and 23 (55%) an internal anal sphincter (IAS) defect. Analysable images of one level of the EAS combined with an analysable IAS were available in 140 (87%) women for EVU and in 131 (81%) for TPU. The sensitivity and specificity for the detection of any defect was 48% (30e67%) and 85% (77e91%) for EVU and 64% (44e81%) and 85% (77e91%) for TPU, respectively. CONCLUSION: Although EAU using a rotating endoprobe is the validated reference standard in the identification of anal sphincter defects, it is not universally available. However while TPU and/or EVU with conventional ultrasound probes can be useful in identifying normality, for clinical purposes they are not sensitive enough to identify an underlying sphincter defect.

“…Outros estudos relataram que o comprimento do canal anal variou entre 3,27 e 3,4 cm, em homens e entre 2,52 e 2,93 cm, nas mulheres. [28][29][30][31] Esses dados justificaram os resultados que encontramos em pesquisa anterior, em que a eficácia da citologia anal foi superior quando as amostras foram obtidas até quatro cm, quando comparadas às conseguidas em 2 cm. 22 Em relação ao tipo de coleta, atualmente dispomos do método do Papanicolaou, em que as amostras são colhidas com escova (cytobrush) e o método da coleta úmida, o Thin Prep, em que a escova vem acondicionada em meio líquido e retorna a esse após seu uso.…”

OBJETIVO: comparar os resultados da coleta única com duas amostras para avaliar se haverá melhora da sensibilidade e especificidade do exame. MÉTODO: Foram 112 doentes masculinos HIV-positivo com doença anal pregressa ou atual pelo Papilomavírus humano (HPV). As lesões HPV induzidas foram observadas em 58 deles. Colhemos material do canal anal utilizando duas escovas (cytobrush) Comparamos estatisticamente os resultados da primeira amostra com a soma das duas coletas. RESULTADOS: dos 58 doentes com lesões clínicas, a primeira amostra confirmou a doença em 40 (69%) e a soma das duas coletas revelou lesões em 51 (88%). Os resultados mostraram sensibilidade de 69% com a primeira coleta e 88% quando somadas as duas amostras. Essa diferença foi confirmada estatisticamente. A especificidade foi menor para as duas amostras, porém sem diferença estatística. CONCLUSÃO: Concluímos que a sensibilidade foi maior e a especificidade foi semelhante quando os resultados foram obtidos com a somação das duas amostras da citologia anal.

“…However, at older ages, ES muscle could be thinner [16] . Recently, some studies found that 3D-ERUS could provide more information on the anal sphincters than traditional 2D-ERUS and might be able to measure sphincter accurately to predict the presence of ES atrophy [17] . The anterior ES of female is much shorter than that of the male, and this normal anatomical characteristic may be confused with an ES defect.…”

Endorectal ultrasound (ERUS) has become an acknowledged technique for imaging anal sphincters, rectum and pelvic floor in the patients with different kinds of anorectal diseases. ERUS can accurately depict internal sphincter (IS) and external sphincter (ES). Therefore, it is valuable in the diagnosis of faecal incontinence and perianal fistulae. Besides, it is reliable for staging rectal tumors, even after neoadjuvant therapy, and is widely used in the surveillance of rectal cancer patients. The paper mainly reviews the indications and application of ERUS in clinical practice, and some new developments of ERUS.
