title: [Endosonographic diagnosis of metastatic tumors in the recto-uterine or recto-vesical space by transrectal scan].
abstract: A 6-year experience of transrectal ultrasonography (TRUS) in 75 patients with advanced gastrointestinal cancers was reviewed regarding the diagnostic yield of metastatic extrarectal tumors. A diagnostic capability of TRUS (a sensitivity of 82.9%, a specificity of 97.5% and an accuracy of 90.7%) was statistically superior to that of digital rectal examination (a sensitivity of 62.9%, a specificity of 75% and an accuracy of 69.3%). However, TRUS could hardly correctly diagnose a miliary type of extrarectal tumors in contrast to nodular and thickened types. TRUS also had an advantage over conventional ultrasonography in detecting a small amount of ascites with a sensitivity of 75%, a specificity of 93% and an accuracy of 86.6%. Patients with positive signs of extrarectal tumors or ascites on TRUS survived significantly shorter than those with negative signs. TRUS renders a convenient means in the objective diagnosis of peritoneal carcinomatosis, and predicts patient's prognosis.
