Abstract Objective: Predictive factors of damage to the Fallopian tube may guide the treatment for patients with tubal pregnancy. The purpose of this study was to evaluate the predictive value of ultrasonographic findings in patients affected by ampullary pregnancy for the determination of the depth of trophoblastic infiltration into the tubal wall on histological examination. Material and methods: 38 patients with ampullary pregnancy undergoing salpingectomy were enrolled into the study. The patients were divided into two subgroups depending on their transvaginal sonography (TVS) findings; either an ectopic gestational sac containing an embryo with cardiac activity or those with a tubal ring. The ampullary pregnancies were histologically classified according to the depth of infiltration of trophoblastic tissue into the tubal wall as follows: stage I: limited to mucosa; stage II: extension to the muscularis layer; stage III: complete infiltration of the tubal wall with or without rupture of the serosa. The association between findings on TVS and stage of trophoblastic invasion, serum beta-human chorionic gonodatropin (`-hCG) levels was evaluated. Results: Although there was no significant difference among two groups in terms of histological stage of trophoblastic infiltration (p=0.257), patients in whom an embryo with cardiac activity had been identified were found to have higher percentage of stage II (47.8%) or stage III (8.7%) invasion. However, there was a significant difference in serum `-hCG levels on the day of surgery among the two groups (p=0.028). Conclusions: Ultrasonographic aspect of ampullary pregnancy is associated with depth of trophoblastic infiltration into the tubal wall and serum `-hCG levels.. Key words: ampullary pregnancy /

Streszczenie Cel: Czynniki predykcyjne zniszczenia jajowodu mogą być pomocne w leczeniu pacjentek z ciążą jajowodową. Celem badania była ocena wartości prognostycznej badania ultrasonograficznego u pacjentek z ciążą bańkową dla określenia rozległości naciekania trofoblastu w obręb ściany jajowodu potwierdzonego w badaniu histopatologicznym. Materiał i metoda: Do badania włączono 38 pacjentek z ciążą bańkową, u których wykonano usunięcie jajowodu. Pacjentki podzielono na dwie podgrupy pod względem różnych obrazów ultrasonograficznych; jeden z widocznym pęcherzykiem ciążowym i z zarodkiem z czynnością serca, drugi z widocznym pierścieniem jajowodowym. Ciąże bańkowe podzielono na podstawie wyniku histopatologicznego, pod względem głębokości nacieku trofoblastu w ścianę jajowodu: stopień I: ograniczone do śluzówki, stopień II: przechodzące na mięśniówkę, stopień III: całkowite nacieczenie ściany jajowodu z /bez pęknięcia surowicówki. Oceniono związek pomiędzy obrazem ultrasonograficznym, stopniem nacieczenia ściany jajowodu oraz poziomem surowiczego beta hCG. Wyniki: Nie znaleziono istotnych różnic pomiędzy badanymi grupami pod względem histologicznie ocenionego nacieku trofoblastu (p=0,257). Jednak kobiety, u których stwierdzano żywy zarodek częściej miały stopień II (47,8%) lub III (8,7%) inwazji trofoblastu. Znaleziono również istotną różnicę poziomu beta-hCG w dniu operacji pomiędzy dwoma grupami (p=0,028). Wnioski: Pewne ultrasonograficzne aspekty ciąży bańkowej są związane z głębokością inwazji trofoblastu w ścianę jajowodu oraz surowiczym beta-hCG.. Słowa kluczowe:
