Tubal obstruction refers to the blockage of fallopian tube in medicine, which can be treated by laparoscopic surgery and hysteroscopic surgery. 1. Laparoscopic surgery: the use of laparoscopy and other related instruments for tubal insertion and unblocking, for patients with distal tubal blockage, can be carried out through laparoscopy, tubal stoma, tubal umbilicoplasty and so on. 2. Hysteroscopic surgery: It is the treatment of tubal cannulation and drug injection under hysteroscopy. Hysteroscopic surgery is recommended to be performed one week after menstruation is clean, and the pulse and vaginal bleeding should be noted after the surgery. For patients with blocked fallopian tubes, it is recommended to go to regular hospitals and cooperate with doctors for standardized treatment. If you are still not pregnant after undergoing the procedure, in vitro fertilization-embryo transfer technique can be considered.
