What are the treatment methods for tubal obstruction or patency? There are many treatment methods for tubal obstruction or patency, such as medication, local anti-inflammatory treatment, microwave physical therapy, surgery, etc. The efficacy varies and needs to be selected according to the patient’s condition. Clinical studies over the years have found that different treatment methods are more targeted and efficient depending on the specific site of tubal obstruction. At present, the more effective and mainstream treatment method is surgery, and the specific surgical methods are as follows. 1. tubal lavage and hysterosalpingography Tubal lavage and imaging are mainly a means of examination to determine the degree of tubal patency; imaging can further discover the site and mode of obstruction with higher accuracy. For patients with loose adhesions and mild obstruction, it has a certain therapeutic effect. Some patients with mild obstruction can be cured by fluid or imaging, but the possibility of cure is very low, because of the blindness of fluid flow, where the fluid finally flows and whether it enters the fallopian tube will not be known. 2.Interventional tubal reversal The interventional method is mainly suitable for patients with obstruction in the proximal part of the fallopian tube, i.e. interstitial or isthmus. Selective tubal imaging is performed under the simultaneous monitoring of a clear DSA (digital imaging angiography machine) and recanalization is performed with an ultra-soft guidewire. It mainly uses the propulsive dilating and separating action of the catheter and the impact of the contrast agent, etc. to unblock the fallopian tubes to the umbilical end. Interventional recanalization is performed under direct X-ray fluoroscopy, and both the surgeon and the patient’s family can clearly observe the whole procedure at a glance, which is less painful, minimally invasive, can be completed in 30 minutes, and also inexpensive, does not require hospitalization, and can go home the same day. The success rate of the procedure can be more than 95%. If the operation is not successful it does not affect the hysteroscopic treatment and IVF. 3.Laparoscopy, laparoscopy or combined hysterolaparoscopy This procedure is mainly suitable for obstruction or hydrocele at the umbilical end of the fallopian tubes. For some patients with proximal or middle obstruction, the purpose of recanalization can also be achieved by loosening the adhesions around the fallopian tubes and ovaries, and in a small number of patients, tubal reanastomosis at the obstruction can also be performed. This method requires incision of the fallopian tubes, which is another injury to the already bad fallopian tubes, and it also requires general anesthesia, artificial pneumoperitoneum, hospitalization and is expensive. The postoperative re-infarction rate is high and scarring and adhesions within the surgical area are inevitable. Statistics show that postoperative pregnancy can reach up to 50%.
