Oviduct blockage is the blockage in one or both microscopic fallopian tubes that allow a woman's egg to pass from her ovaries to her uterus. The blockage is an impediment for the egg to migrate, implant and begin pregnancy. The result is infertility. In rare cases, even if pregnancy occurs it can be dangerous, if not treated immediately.
Diagnosing oviduct blockage
Laparoscopic chromotubation: Usually done after sedating with a mild anesthetic, laparoscopy involves making a very small incision in the belly button and near the pubic bone area; a small camera helps view the tubes. Laparoscopy helps detect endometriosis, adhesions, and ovarian cysts and also check the tubes.
Chromotubation involves infusing diluted methylene blue dye solution into the uterine and tubal lumen. If the tubes are not blocked, the dye should come out of the ends of the tubes into the peritoneal (abdomen) cavity. This test is considered the most reliable way to determine oviduct blockages.
Both laparoscopic chromotubation and Hysterosalpingogram can sometimes open a blocked tube; hence these procedures can be both diagnostic and therapeutic. The rate of fertility is likely to improve after the procedure.
Falloscopy: The newest form of endoscopic examination, falloscopy is helpful to look inside the fallopian tubes. Using a catheter-based system, a flexible tube is inserted through the vagina and cervix which threads through one of the fallopian tube. Very similar to hysterosalpingogram, it allows viewing of tubal walls and checks if it is healthy and also detects obstruction, if any.
Sonohysterography: This is a non-invasive procedure wherein fluid is injected through the cervix into the uterus, and ultrasound imaging is used to determine if any abnormality is present. The procedure is extremely helpful in detecting underlying cause of many problems such as abnormal uterine bleeding, infertility and repeated miscarriage. Like the other diagnostic procedures, sonohysterography is done when the woman is not having her menstrual cycle.
Oviduct blockage treatment
The goal of treating oviduct blockages is to unblock fallopian tubes and increase the chances for a successful pregnancy. Surgical procedures are the primary treatment option to open blocked oviducts. If needed, doctors will use more than one procedure to treat oviduct blockage. Take a look at the various surgical and non-surgical options available today to treat this particular condition.
Laparoscopy: To treat oviduct blockages, laparoscopy is widely preferred. It involves inserting the scope into the abdomen and cutting away scar tissue which blocks the tubes and is a result of infection and/or endometriosis, primary causes for oviduct blockages. It helps in unblocking the oviducts and allows the eggs and sperm to meet and facilitates the egg to become fertilized.
Recanalization: A tiny wire is inserted into the tube to remove the blockage.
Salpingectomy: It involves removing a blocked fallopian tube or sealing it in order to maximize the functioning of the second, unblocked tube.
Tubal Reanastomosis: This is also a laparoscopic procedure in which small incisions are made through the abdomen. The blocked portion of the oviducts or fallopian tube is cut away and the healthy sections of the tube are connected. It is followed by a procedure called Salpingostomy to create a new opening in the tube close to the ovary.
Fimbrioplasty: This plastic surgery that facilitates to reshape ends of fallopian tubes closed off by scar tissue or some other blockage.
Tubal Cannulation: Is a non-surgical option which involves clearing blockages with the use of a catheter, or Cannula that is inserted through the uterus into the fallopian tube.
