Conservative treatment of ectopic pregnancy with local injection of hyperosmolar glucose solution or prostaglandin-F2 alpha: a prospective randomised study.

In a prospective randomised study, 31 patients with an unruptured tubal pregnancy were treated either with local and systemic prostaglandins or with local instillation of a hyperosmolar glucose solution. Prostaglandin therapy was successful in 13 of 15 patients and glucose therapy in 16 of 16. 9 women treated with prostaglandins had cramping abdominal pains postoperatively. No side-effects were noted in those treated with glucose. At subsequent hysterosalpingography 5 of 6 patients treated with prostaglandins and 7 of 8 treated with glucose had normal tubal configuration and patency. 3 patients treated with glucose later had a normal intrauterine pregnancy, demonstrably through the affected tube in 1 case. These results suggest that local instillation of hyperosmolar glucose solution is an option in the laparoscopic management of unruptured tubal pregnancies.
