Computed tomographic colonography vs rectal water‐ contrast transvaginal sonography in diagnosis of rectosigmoid endometriosis: a pilot study

Abstract

Objectives To compare the performance of computed tomographic colonography (CTC) and rectal water-contrast transvaginal sonography (RWC-TVS) in

Transvaginal sonography with vs without bowel preparation in diagnosis of rectosigmoid endometriosis: prospective study

“…In the current study, TVS was used to estimate the distance between the lower margin of the more caudal nodule and the anal verge. The consensus of the IDEA group, reviews by experts and clinical studies support the use of TVS in measuring this distance. However, while this measurement can easily be performed in the case of rectal nodules, it may be less precise when the endometriotic nodules are located on the rectosigmoid junction or on the sigmoid.…”

A Prospective Study Comparing Three-Dimensional Rectal Water Contrast Transvaginal Ultrasonography and Computed Tomographic Colonography in the Diagnosis of Rectosigmoid Endometriosis

“…The scans were performed by using a 64-section multidetector CT scanner (LightSpeed, GE Healthcare, Milwaukee, WI, USA) according to a standardized protocol [27]. A 12F Foley catheter was introduced into the distal rectum before the scan on the CT bed, and 2.5-3 L of room air were introduced in the colon, calculating the same number of manual pomp inflations in all the distensions.…”

“…Rectosigmoid endometriotic nodules appear on CTC as strictures usually involving a variable part of the circumference of the bowel wall ( Figure 1); the site of these findings is constant on both the supine and prone scans and stenosis may be highlighted by the 3D endo-luminal FT reconstructions ( Figure 2). The MPRs sometimes allow for the detection of a transmural involvement of the endometriotic nodule [27].…”

“…Computed colonography (CTC) is used worldwide for the screening of colorectal cancer. Over the last ten years, several studies showed that CTC has high diagnostic performance in the diagnosis of rectosigmoid endometriosis [22][23][24][25][26]; this exam is as accurate as TVS in diagnosing rectosigmoid endometriosis and has the advantage of investigating the whole colon [27]. Image post-processing is performed using workstations suitable for 3D data management and reconstruction.…”

Clinical picture and diagnosis of genital endometriosis

“…Точность трансвагинального ультразвукового исследования с наполнением кишки водой при диагностике ректосигмоидного эндометриоза и оценке размеров эндометриоидных очагов сопоставима с результатами компьютерной томографии. При этом интенсивность боли, испытываемой во время наполнения кишки воздухом при КТ, была выше, чем во время УЗИ [51].…”
