A Cochrane review found that medical management with misoprostol (Cytotec) in women with incomplete abortion does not improve rates of completed abortion or decrease the need for unplanned surgical procedures compared with expectant management.22 In contrast, medical management is more effective than expectant management for the treatment of anembryonic gestation or embryonic demise.25 The most effective regimen for medical management is 200 mg of oral mifepristone (Mifeprex) followed 24 hours later by 800 mcg of vaginally administered misoprostol.26 Success rates at two days with this regimen are 84% vs. 67% in those treated with misoprostol alone. Only the uterus is physically able to carry a growing fetus. Bleeding equal to or heavier than a menstrual period and bleeding accompanied by pain are associated with an increased risk of early pregnancy loss.2,7 Patients should be assessed for signs and symptoms of hypovolemia.

Ruptured ectopic pregnancy is associated with peritoneal signs and requires emergency surgery, although most patients present with bleeding or pain before rupture.39, Surgical treatment options include salpingectomy or salpingostomy, which are appropriate if the location of the pregnancy is the fallopian tube, but not if there is a less common location.

Compared with sharp curettage, vacuum aspiration is associated with decreased pain, shorter procedure duration, and less blood loss.28 Office-based uterine aspiration is safe, less expensive, and often more convenient than treatment in the operating room.29,30 Choices about analgesia during the aspiration procedure should be made with the patient's input.

In this case, a repeat dose of methotrexate may be given, although surgery may be required if the patient is symptomatic.
