A New Dynamic Echodefecography (EDF) Established by Using BK Ultrasound 8838 Transducer and its Testing Results Comparison with X-ray Defecography

ObjectiveTo describe a new dynamic echodefecography(EDF) using BK ultrasound 8838 transducer and compare its testing results with X-ray defecography.MethodThe BK 8838 ultrasound probe is used to evaluate the static 3D scan, dynamic 3D scan and dynamic 2D scan of pelvic floor and compare its testing results with X-ray defecography and defined its value to evaluate the pelvic floor disease.ResultsFifty-seven patients were studied (24 male and 33 female). Forty seven patients were diagnosed as anismus by EDF and 46 patients were diagnosed as anismus by X-ray defecography. Sixteen patients were diagnosed as rectocele by X-ray defecography, among which eight were classified as mild(6-15mm), 4 as moderate(16-30mm) and 4 as severe(over 30mm).Fourteen patients with constipation and 2 patients with anal pain were diagnosed as intussusception by EDF, but only 3 patients were diagnosed as intussusception by X-ray defecography. Two patients with constipation were diagnosed as perineal descent by EDF and none by X-ray defecography. Two patients were diagnosed as enterocele by EDF as well as X-ray defecography.ConclusionThe EDF established by BK 8838 ultrasound probe can show clear anatomy and real time movement of pelvic floor muscle. The EDF is more sensitive to the diagnosis of intussusception, perineal descent(PD) and anal spincter defect than X-ray defecograpgy. For anismus,rectocele and enterocele,the diagnosis results are comparable between EDF and X ray defecography. Further study is needed to determine its clinical values to evaluate the pelvic disease.

Defecography by digital radiography: experience in clinical practice

Objective: The objective of this study was to profile patients who undergo defecography, by age and gender, as well as to describe the main imaging and diagnostic findings in this population. Materials and Methods: This was a retrospective, descriptive study of 39 patients, conducted between January 2012 and February 2014. The patients were evaluated in terms of age, gender, and diagnosis. They were stratified by age, and continuous variables are expressed as mean ± standard deviation. All possible quantitative defecography variables were evaluated, including rectal evacuation, perineal descent, and measures of the anal canal. Results: The majority (95%) of the patients were female. Patient ages ranged from 18 to 82 years (mean age, 52 ± 13 years): 10 patients were under 40 years of age; 18 were between 40 and 60 years of age; and 11 were over 60 years of age. All 39 of the patients evaluated had abnormal radiological findings. The most prevalent diagnoses were rectocele (in 77%) and enterocele (in 38%). Less prevalent diagnoses were vaginal prolapse, uterine prolapse, and Meckel's diverticulum (in 2%, for all). Conclusion: Although defecography is performed more often in women, both genders can benefit from the test. Defecography can be performed in order to detect complex disorders such as uterine and rectal prolapse, as well as to detect basic clinical conditions such as rectocele or enterocele.
