Hi welcome to H.C.M.Forum. there are several types of operations depending upon the place of occlusion and complete or incomplete.if partial occlusion or scaring occlusion is near the uterus
,selective tubal canulation by fluroscopy
is done by P.V route. if occlusion is near the ovary fibrinoplasty is done. if block is large salpingoplasty is done laparatomy opening the abdomen or laproscopy.by any means re occlusion is possible. if one side done first . 2nd side you can have chance to get it done as 2nd trial. thank you.
