OBJECTIVE: To evaluate the ability of noninvasive diagnostic tools to predict tubal rupture and active bleeding in patients with tubal pregnancy. DESIGN: Prospective cohort study. SETTING: Two large teaching hospitals in Amsterdam, The Netherlands. PATIENT(S): Consecutively seen patients with suspected tubal pregnancy who were scheduled to undergo confirmative laparoscopy. MAIN OUTCOME MEASURE(S): Tubal rupture and/or active bleeding confirmed at laparoscopy. RESULT(S): Sixty-five (23%) of 288 patients had tubal rupture and/or active bleeding at laparoscopy. Abdominal pain, rebound tenderness on abdominal examination, fluid in the pouch of Douglas at transvaginal ultrasound examination, and a low serum hemoglobin level were independent predictors of tubal rupture and/or active bleeding. Pregnancy achieved with the use of IVF-ET and the presence of an ectopic gestational sac or an ectopic mass at ultrasound examination reduced the risk of tubal rupture. Abdominal pain was the most sensitive predictor, with a sensitivity of 95%. CONCLUSION(S): Because the nonsurgical management of tubal pregnancy should be used only when the risk of tubal rupture and/or active bleeding is low, it can be safely applied in only a limited number of patients.
