| Cohen et al. (2013) | Laparotomy (n = 48) vs. laparoscopic surgery (n = 12) for ectopic pregnancy with hemoperitoneum > 800 mL | Preoperative and postoperative hemoglobin levels, blood transfusion quantity, complication frequency, and hospitalization duration | Amount of bleeding was lower and operative time was shorter | Not available |
| Beuran et al. (2016) | Laparotomy (n = 28) vs. laparoscopic surgery (n = 27) for ruptured tubal pregnancy and ruptured ovarian cyst with massive hemoperitoneum > 500 mL | Degree of hemoglobin level reduction, blood transfusion quantity, postoperative complication rate | Not available | Not available |
| Snyman et al. (2017, randomized trial) | Laparotomy (n = 69) vs. laparoscopic surgery (n = 70) for ectopic pregnancy involving rupture | Frequency of blood transfusion | Hospitalization duration and recovery duration were shorter and pain was lower | Operative time was longer (67.3 min vs. 30.5 min, p < 0.0001) |
