Pathology report

Okay ladies. I finally got my OR/pathology report from my last csection which included tubal ligation. My or report said there was significant tube removal sufficient to prevent further pregnancy. However nearly 3 years later I had become pregnant and MC. At the time I had become pregnant I contacted my dr bc I was confused by the positive tests. He seemed really irritable towards me when I brought the subject up. But I had an ultrasound baby was in my uterus not ectopic but I miscarried due to possible abnormalities he said. 
While looking over my pathology report today I discovered he barely removed and cauterized a centimeter worth of tube. My tubes were still close together and most likely healed back together partially. 
My question is has this happened to anyone before?
How much tube did you have removed if you know? 
And should I still go through with my tubal reversal surgery or would you think I'd need to?
