Local danazol injection for treatment of unruptured tubal pregnancy (preliminary experience)

Fifteen women with unruptured tubal pregnancies diagnosed by laparoscopy and ultrasound were treated with danazol 400 mg, injected directly into the affected tube. Study inclusion criteria were (i) a rising or plateauing level of serum beta human chorionic gonadotropin (hCG), (ii) a tubal swelling less than 3 x 3 cm, (iii) an intact tubal serosa and (iv) no active bleeding. The women were monitored with serial measurements of beta-hCG. All women responded to a single danazol injection, no treatment failures were observed. After 3 months, hysterosalpinography revealed tubal pateny on the involved side in 14 patients and in 1 patient the tube was blocked. Within 1 year after danazol therapy patients were attempting to or had conceived. Of these, there were 3 intrauterine pregnancies and 2 recurrent contralateral pregnancies.
