Computerized videodefecography versus defecography: do we need radiographs?

Abstract: Computerized videodefecography is equivalent to the traditional defecography examination. It has the advantage of offering reduced radiation exposure through saving on the use of radiography.

“…Recently, because of its high radiation exposure to young and elderly patients, some authors have performed videodefecography using only video recording, without radiography, whereas others have chosen magnetic resonance defecography or echodefecography, which are well correlated with the results obtained by VDG, without the use of ionizing radiation. 28,29 (g) Colonic Transit Time (CTT): The CTT examination is conducted to assess the time required for elimination of the feces and may be performed with the use of radiopaque markers or by the scintigraphy method. 25 A capsule containing 24 radiopaque markers is swallowed and an abdominal radiography is taken 5 days later.…”

“…O exame de videodefecografia computadorizada é realizado da mesma forma que o exame convencional descrito anteriormente, com exceção das radiografias estáticas, que são dispensadas (8)(9)(10) .…”

“…Sobrado et al demonstraram, em estudo com dois grupos de voluntários assintomáticos submetidos a defecografia convencional e videodefecografia computadorizada, que a comparação dos valores dos parâmetros tem forte correlação e sem diferença estatística significativa. Além disso, a exposição à radiação, calculada por dosímetros termoluminescentes, foi significativamente menor no grupo submetido à videodefecografia computadorizada (8) .…”
