A total of 81patients with an ampullary ectopic pregnancy undergoing salpingectomy were enrolled in the study. The ampullary pregnancies were classified according to the depth of trophoblastic infiltration into tubal wall as follows: Stage I, limited to mucosa; Stage II, extension to the tubal muscularis; Stage III, complete tubal wall infiltration up to the serosa. An association was observed between serum -human chorionic gonadotropin (-hCG) levels and the depth of trophoblastic infiltration. Significantly higher severe ischemic changes and rupture of tubal wall were observed in patients with stage III infiltration compared with the other groups. A significant association was found between the absolute depth of trophoblastic invasion and severe ischemic changes, and also rupture of serosa. In conclusion, serum -hCG levels are associated with depth of trophoblastic invasion into the tubal wall, severe ischemic changes, and rupture of the tubal wall.
