Tubal patency was studied in 32 patients who had previously undergone a laparoscopic or laparotomy procedure (salpingostomy, salpingectomy or tubal resection), or who had received a local injection of hypertonic glucose because of tubal pregnancy. Transvaginal salpingosonography (TSSG) was subsequently performed in the follicular phase of the menstrual cycle, and laparoscopic chromopertubation was carried out as a comparative method after TSSG. Of 32 patients (47 Fallopian tubes examined), the affected tube was observed to be patent by TSSG in 68%. The contralateral tube was patent in 93%. Nine patients became pregnant and were thus not subsequently assessed with laparoscopy. Two of these pregnancies ended in a miscarriage and one in a recurrent tubal pregnancy. A concordance of 86% for Fallopian tubes was achieved between the TSSG and laparoscopic chromopertubation methods. When checking the Fallopian tubes separately, the concordance for the results in the affected tubes was 67%, and 100% for the contralateral tube. Therefore TSSG appears to be a practical method for the primary examination of tubal patency in patients treated previously for tubal pregnancy. Guidelines for the treatment of infertility after tubal pregnancy can also be set out according to TSSG findings.
