What is means by early spillage and late spillage in hsg?

Early spillage and late spillage in hysterosalpingography (HSG) refer to the timing of the contrast agent's passage through the fallopian tubes during the procedure. Early spillage indicates that the contrast agent flows through the tubes immediately after injection, suggesting that the tubes are patent (open). Late spillage occurs when the contrast agent spills into the abdominal cavity after a delay, which may indicate potential issues such as tubal blockage or dysfunction. The timing of spillage helps in assessing the reproductive tract's health and functionality.
