Reply:Thank you very much for your special interest in our article.We only performed laparoscopic surgery in two cases due to ectopic pregnancy after IVF-ET and sclerotherapy. There were no other cases of laparoscopy due to pain or adhesion after hydrosalpinx sclerotherapy.Some patients complained of pain on the day of surgery or during immediate follow-up; however, no one complained of long-term pain because our method had different outcomes from that of the correspondent.Alcohol was used as a sclerosing agent, and tetracycline emulsion was applied as a final residual sclerosing agent [1]. First, the alcohol was injected approximately ten times into the hydrosalpinx as an irrigation agent. Then, after the alcohol was completely removed, 1-1.5 mL of the tetracycline emulsion, which was prepared by dissolving one or two 250-mg tablets of Teracyclin into distilled water, was finally injected into the hydrosalpinx area.No cases with long-term pain and laparoscopy, and no cases with the symptoms of suspected intraperitoneal adhesion occurred.Hospitalization is unnecessary for this procedure. We believe this procedure would be a simpler and more appropriate method than IVF-ET. It is suggested that further studies be performed on this procedure.
