Definition - What does Chromopertubation mean?
Chromopertubation is a procedure performed in combination with a surgical procedure called laparoscopy to visualize the fallopian tubes with the purpose of assessing their patency (openness) by inserting a dye through the fallopian tubes. ('Chromo' implies color and 'pertubation' is through the tubes.) The procedure is typically performed under general anesthesia. Chromopertubation with laparoscopy is an essential component of the diagnostic workup of infertility.
FertilitySmarts explains Chromopertubation
Open fallopian tubes are critical for achieving a successful pregnancy as the sperm travels all the way to the tubes to fertilize an egg. As part of an infertility investigation, it is often essential to determine whether the woman's fallopian tubes are open or not.
As part of the procedure, a small cut is made on the skin of the abdomen and an instrument called laparoscope is inserted into the abdomen. A dilute blue dye is injected via a metal or plastic tube that is inserted through the cervix into the uterus, facilitating the entry of the colored dye into the uterine cavity and fallopian tubes. If the tubes are open, the dye can be observed spilling out of the ends of the tubes as seen through the camera of the laparoscope. In contrast, if the tubes are blocked, the dye will flow back into the cavity of the uterus.
Chromopertubation is regarded as a gold standard test to assess the patency of tubes. However, being an invasive procedure, it is considered as a last resort in the evaluation of female infertility and is usually carried out after hysterosalpingogram results have been inconsistent. Apart from evaluating tubal patency, it can also help identify and treat other causes of infertility like pelvic adhesions and endometriosis with the help of laparoscopy.
