Abstract/OtherAbstract:
OBJECTIVE: Predictive factors of damage to the Fallopian tube may guide the treatment of patients with tubal pregnancy. The aim of the present study was to investigate the association between the depth of trophoblastic invasion into the tubal wall, assessed on postoperative histological examination, with the findings obtained on transvaginal sonography (TVS) in women with ampullary pregnancy. METHODS: Women with ampullary pregnancy undergoing salpingectomy were enrolled into the study. Only women with a finding of either an embryo with cardiac activity or a tubal ring on TVS were included in the analysis, a total of 85 patients. Trophoblastic invasion was assessed postoperatively and was histologically classified as Stage I when limited to the tubal mucosa, Stage II when extending to the muscle layer and Stage III in the case of complete tubal wall infiltration. The association between findings on TVS and the stage of trophoblastic invasion was evaluated. RESULTS: There was a significant association between the findings on TVS and the depth of trophoblastic invasion (P < 0.001). All patients in whom an embryo with cardiac activity had been identified were found to have Stage II (17.9%) or Stage III (82.1%) invasion, whereas in those patients who showed a tubal ring on TVS, Stage I invasion was the most frequent finding (41.3%). CONCLUSIONS: In ampullary pregnancy, the finding on TVS of an embryo with cardiac activity is associated with deeper penetration of trophoblastic tissue into the tubal wall than is the finding of a tubal ring.
