I Have Had Two Colon Surgeries And One Hernia So

I have had two colon surgeries and one hernia so far. I just received the CT results and it says I now have a widemouth ventral hernia which I understand all about that. I am a bit perplexed because the results also say my gallbladder is surgically absent??? I don't ever recall my gallbladder being removed. Is there any way they could be mistaken or maybe one of the surgeons removed it while fixing my colon but I do not recall nor does any of my paperwork show my gallbladder being removed???
