Is blocked fallopian tube difficult to treat?

Treatment of fallopian tube obstruction is relatively difficult and depends on the specific site of blockage. If the obstruction occurs in the interstitial portion, the likelihood of successful treatment is relatively low. However, if the blockage is located in the isthmus, ampulla, or fimbrial end of the fallopian tube, hysteroscopy and laparoscopy are often effective in releasing adhesions, thereby restoring tubal patency and achieving pregnancy. Clinically, the majority of fallopian tube obstructions are caused by localized adhesions resulting from chronic salpingitis, which leads to obstructive symptoms. In rare cases, congenital abnormalities such as a blind-ended fallopian tube can also cause clinical obstruction. Surgical intervention is required to restore patency, and patients are advised to attempt pregnancy as soon as possible after surgery, because the tubal lumen is relatively thin and inflammation may lead to re-obstruction and infertility.
