Transvaginal sonography with rectal water contrast accurately diagnoses rectosigmoid endometriosis and intestinal stenosis, performing comparably to transrectal sonography and barium enema.

AI-generated deep summary by claude@2026-06, 2026-06-07

This paper studied the diagnostic accuracy of transrectal sonography (TRS) and a new technique, transvaginal sonography with water-contrast in the rectum (RWC-TVS), for rectosigmoid endometriosis, and the accuracy of barium enema (BE) and RWC-TVS for detecting intestinal stenosis due to endometriosis. In a prospective study of 61 consecutive patients undergoing laparoscopy or laparotomy for suspected rectosigmoid endometriosis, preoperative imaging results were compared with operative and pathologic findings. RWC-TVS achieved the same diagnostic accuracy as TRS for rectosigmoid endometriosis and was equally efficient as BE for detecting significant intestinal lumen stenosis, with reported sensitivities/specificities showing strong performance for both tasks. This paper does not explicitly discuss limitations in the provided text, but it evaluates only rectosigmoid disease in a single prospective surgical cohort, which may constrain generalizability. This paper is centrally about endometriosis — it compares RWC-TVS, TRS, and BE for preoperative assessment of rectosigmoid intestinal endometriosis and related stenosis.
