OBJECTIVE: The aims of this study were to evaluate the effect of the methotrexate (MTX) method by comparing the change of the serum beta-hCG level between the MTX method and salpingectomy for treating tubal pregnancy, furthermore by analyzing differences between the MTX success group and the failure group, and to provide helps in establishing criteria for choosing the MTX method. METHODS: Medical records of the 118 patients who were diagnosed with tubal pregnancy were reviewed retrospectively for the period of January 2006 to December 2007 at Kangnam St. Marys Hospital. RESULTS: Between the MTX success group and the failure group, no difference was observed in pregnancy duration, but statistically significant differences were observed in the size of hematoma and the quantity of hemoperitoneum at the site of tubal pregnancy in ultrasonography and in the serum beta-hCG level (p<0.05). Compared with salpingectomy, the MTX method showed the patterns of a low decrease rate of serum beta-hCG level after treatment and even its increase during the early period of treatment, but the serum beta-hCG level decreased rapidly from Day 7 after treatment and became equal to that of salpingectomy on Day 28 after treatment. CONCLUSION: The size of hematoma and the quantity of hemoperitoneum at the site of tubal pregnancy and the serum beta-hCG level before treatment are important factors for success in the MTX method. The MTX method may be safe and effective relatively in hemodynamically stable tubal pregnancy patients, who need preserve the salpinx particularly.
