Local methotrexate injection: a nonsurgical treatment of ectopic pregnancy.

Twenty seven patients with unruptured tubal pregnancy were selected for nonsurgical treatment with the use of one injection of 12.5 mg of methotrexate into the ectopic site at laparoscopy. No adverse reactions were observed. In three patients (11%), a laparotomy was performed because of rising beta-human chorionic gonadotropin titers. In the other patients, serum beta-human chorionic gonadotropin levels decreased to the nonpregnant range with no further intervention, and the patients recovered uneventfully. This method is suggested as an alternative to surgery in selected cases of early unruptured tubal pregnancy.
