Objective: Management of early ectopic pregnancy was investigated in a multicenter, prospective study.
Methods: Serum beta-hCG levels were monitored after therapy and correlated to the type of management, gestational age, and initial serum beta-hCG levels in 119 patients with ectopic pregnancies detected at 5-7 postmenstrual weeks.
Results: Salpingectomy was performed in 16 patients. No post-operative complications were reported. After conservative laparoscopic surgery of 51 ectopic pregnancies, 9 (18%) had delayed decrease or an increase of serum beta-hCG levels. Re-operations were performed in 4 (7%) patients. Similar findings were noted in 2/6 patients after conservative operations performed by laparotomy. Intrachorionic injection treatment was successful in 17/18 ectopic pregnancies, and expectant management in 7/8 patients with initial serum beta-hCG levels below 250 mIU/ml.
Conclusions: Persistence of trophoblastic activity is a potential complication of conservative surgical treatment of ectopic pregnancy. A detailed diagnosis as early as 6-7 post-menstrual weeks may be the key for future non-surgical management of ectopic pregnancy.
