Rectal water contrast transvaginal ultrasound versus double-contrast barium enema in the diagnosis of bowel endometriosis.


ABSTRACT:

Objectives

The aim of study was to compare the accuracy between rectal water contrast transvaginal ultrasound (RWC-TVS) and double-contrast barium enema (DCBE) in evaluating the bowel endometriosis presence as well as its extent.

Design and setting

198 patients at reproductive age with suspicious bowel endometriosis were included. Physicians in two groups specialised at endometriosis performed RWC-TVS as well as DCBE before laparoscopy and both groups were blinded to other groups' results. Findings from RWC-TVS or DCBE were compared with histological results. The severity of experienced pain severity through RWC-TVS or DCBE was assessed by an analogue scale of 10?cm.

Results

In total, 110 in 198 women were confirmed to have endometriosis nodules in the bowel by laparoscopy as well as histopathology. For bowel endometriosis diagnosis, DCBE and RWC-TVS demonstrated sensitivities of 96.4% and 88.2%, specificities of 100% and 97.3%, positive prediction values of 100% and 98.0%, negative prediction values of 98.0% and 88.0%, accuracies of 98.0% and 92.4%,?respectively. DCBE was related to more tolerance than RWC-TVS.

Conclusions

RWC-TVS and DCBE demonstrated similar accuracies in the bowel endometriosis diagnosis; however, patients showed more tolerance for RWC-TVS than those with DCBE.
