How to avoid ectopic pregnancy?

Hi doctor,

My wife had first ectopic pregnancy before two years and her left tube was ruptured. She had laparoscopic surgery at that time and the bleeding was stopped by laser and the tube was left in ruptured condition. After one year we tried, but did not conceive. After two years of the incident, she was diagnosed with uterine tuberculosis and the ATT was started before five months. Doctor informed me to try to conceive while ATT is going on. We have tried and she conceived, but after one month she was diagnosed as cornual ectopic and had laparoscopic surgery. This time, neither the uterus wall nor the tube has ruptured. I want to know that in future will she pregnant successfully or not. Please help.

Thank you doctor,

Her HSG was done seven months ago and everything was normal in that. Before two years, right tube was normal and left tube was ruptured. She conceived by right tube, but the sac walk to left tube cornual end and this time repeatedly left side cornual pregnancy happened. Right tube is still safe. Her ESR rate was 84 before five months before starting of ATT and PPD test was 20 mm, so positive. Yesterday, her stitches were removed. We both are very much depressed. She is very afraid of future pregnancy. I want to know the test do be done in the future to confirm that everything is fine to conceive. Is there any solution available that she will not suffer by ectopic repeated in future?
