A doctor at a clinic i'm going for my mini hysteroscopy has his license restricted for messing up in surgery. should i judge the other doctors&avoid?

Not at all : This is life things happen ,if it happened with one person that does not mean it will happen with another doc too

Depends: Your choice of physician depends on alot of criteria. You have been searching. If you don't feel comfortable find a doctors office in which you have complete trust and will get the best outcomes.

Agree with Dr Modi: I'd be suspicious of anyone having made multiple mistakes in surgery although anyone is entitled to one or two in a long career. Judging the competency of the entire profession based on the misdeeds of a few is akin to considering all people criminals because a few have committed terrible crimes. Check reputation on line and consult PCP & friends in the future. Get a 2nd opinion if necessary.
