Is this trial a fit for you?

Likely a good fit

People scheduled for minimally invasive uterine-preserving myomectomy at MedStar who have at least one fallopian tube, can have a uterine manipulator placed, are not pregnant, and have no methylene blue allergy or G6PD deficiency.

Probably not a fit

Patients with absent tubes, known tubal disease or prior tubal surgery, allergy to methylene blue or G6PD deficiency, inability to place a uterine manipulator, or those not undergoing myomectomy are unlikely to benefit from participation.

What this trial studies

This single-center interventional study uses chromopertubation during laparoscopic or robotic uterine-preserving myomectomy to document tubal patency before and after fibroid removal. A dilute methylene blue solution is introduced into the uterus during surgery to see whether dye spills from the fallopian tubes, with the minimum dye dose used to reduce risk. Patients with prior tubal surgery, known tubal occlusion, absent tubes, pregnancy, methylene blue allergy, or G6PD deficiency are excluded. The goal is to clarify whether fibroids or their surgical removal affect tubal openness and thus could influence fertility counseling and management.

Why it matters

Potential benefit: If successful, the results could help doctors know whether removing fibroids restores or preserves tubal openness and may improve guidance on chances for natural pregnancy.

How similar studies have gone: Chromopertubation itself is an established technique for checking tubes, but there are very few prospective studies specifically measuring tubal patency before and after myomectomy, so this application is relatively novel.
