[Oral methotrexate in trophoblast seeding after laparoscopically treated tubal pregnancy].

The atypical course after laparoscopic conservative treatment of tubal pregnancy is described. Routine measurements of the serum HCG levels postoperatively showed, after a short period of decreasing HCG levels, a new increase of HCG values. Under the suspicion of a disseminated intraperitoneal trophoblastic tissue the patient was treated with 20 mg methotrexate q.i.d. per os for 5 days, as a result of which HCG levels returned to normal within a short time.
