title: [Studies on non-surgical therapy of tubal pregnancy].
abstract: 8 cases of tubal pregnancy in the pre-abortional stage were detected by B-scope examination. The administration of MTX (total doses: 60-300mg) resulted in complete remission in 7 cases; the other received tubectomy because of the progression of abortion. The dose of MTX used to obtain remission is responsible for the HCG titer of urine before the treatment; 60-150mg of MTX was sufficient in cases which showed a titer below 1,000iu/l, although 75-300mg was necessary in cases over 4,000iu/l. The patency of tubes after the regimen was confirmed in 4 out of 5 cases with hystero-salpingography. Serious side effects were not observed in the present study in spite of the great efficacy; transient suppression of liver has been observed in 2 cases. Two patients had normal intra-uterine pregnancy subsequent to the treatment; one had a matured full-term female neonate and the other received D & C in 9 gestational weeks. These results suggest that the MTX regimen is practical for the treatment of patients with tubal pregnancy. This is characterized by unimpaired fertility following the treatment, although the detection of patients in the pre-abortional stage is absolutely necessary.
