title: Local injection of methotrexate dissolved in saline versus methotrexate suspensions for the conservative treatment of ectopic pregnancy.
abstract: To compare the local injection of methotrexate (MTX) dissolved in saline and MTX suspensions for the laparoscopic treatment of ectopic pregnancy in terms of success rate and postoperative tubal patency. A total of 26 patients with unruptured ectopic pregnancies were selected from among 60 women with ectopic pregnancies admitted to the Nagasaki University clinic. Of these patients, 12 were treated with MTX dissolved in saline solution (solution group) and 14 with MTX suspensions consisting of lipiodol (LPD) with phosphatidylcholine (PC) added as a dispersing stabilizer (suspension group). Except for one case treated under transvaginal guidance, all the patients were treated by laparoscopy. Persistent ectopic pregnancy was recognized in seven cases (58%) in the solution group but in only two cases (14%) in the suspension group. Moreover, rupture occurred in two cases in the solution group but in no case in the suspension group. A patent treated tube was found in seven of 10 cases in the saline group and in 10 of 12 cases in the suspension group. During the follow-up period of 6-31 months, five women in the saline group and three women in the suspension group had an intrauterine pregnancy. In this study, the local injection of MTX is considered to be a reasonable method for the treatment of unruptured ectopic pregnancy, and the MTX suspension seems to be more effective and useful than MTX solution.
