Benefits and risks
When NICE looked at the evidence, it decided that the procedure was safe enough and worked well enough to be used in the NHS for this condition. The 9 studies that NICE looked at involved a total of 4548 patients.
Generally, they showed that after hysteroscopic metroplasty women were less likely to have a miscarriage or to give birth prematurely.
The studies showed that the risks of hysteroscopic metroplasty included:
damage to the womb or cervix during the procedure
complications during the procedure, such as excessive bleeding or fluid collecting in the lungs
scar tissue forming in the womb after the procedure
the womb rupturing during pregnancy or delivery
1 woman had an ectopic pregnancy after the procedure. A pregnancy is ectopic when it happens outside the womb (for example, in the tubes that carry the egg to the womb).
