Input: Thirty five studies have been analyzed on the treatment of tubal ectopic pregnancy, describing 25 different comparisons.   Surgery  Laparoscopic salpingostomy is significantly less successful than the open surgical approach in the elimination of tubal ectopic pregnancy (2 RCTs, n = 165, OR 0.28, 95% confidence interval (CI) 0.09 to 0.86) due to a significant higher persistent trophoblast rate in laparoscopic surgery (OR 3.5, 95% CI 1.1 to 11). However, the laparoscopic approach is significantly less costly than open surgery (P = 0.03). Long term follow up (n = 127) shows no evidence of a difference in intra uterine pregnancy rate (OR 1.2, 95% CI 0.59 to 2.5) but there is a non significant tendency to a lower repeat ectopic pregnancy rate (OR 0.47, 95% 0.15 to 1.5). Medical treatment  Systemic methotrexate in a fixed multiple dose intramuscular regimen has a non significant tendency to a higher treatment success than laparoscopic salpingostomy (1 RCT, n = 100, OR 1.8, 95% CI 0.73 to 4.6). No significant differences are found in long term follow up (n=74): intra uterine pregnancy (OR 0.82, 95% CI 0.32 to 2.1) and repeat ectopic pregnancy (OR 0.87, 95% CI 0.19 to 4.1). Expectant management  Expectant management is significantly less successful than prostaglandin therapy (1 RCT, n = 23, OR 0.08, 95% CI 0.02 to 0.39). In the surgical treatment of tubal ectopic pregnancy laparoscopic surgery is a cost effective treatment. An alternative non surgical treatment option in selected patients is medical treatment with systemic methotrexate. Expectant management can not be adequately evaluated yet.
Output:

This review of 35 randomised controlled trials found that laparoscopic surgery is feasible and less expensive than open surgery in the treatment of tubal ectopic pregnancy. In selected patients, non-surgical treatment options can be used. Medical treatment with systemic methotrexate is an option for women with tubal ectopic pregnancy with no signs of bleeding whose pregnancy hormone blood levels are relatively low. An evaluation of expectant management of tubal ectopic pregnancy cannot be adequately made yet.
