Dr. Jan Adams is in big trouble after the death of his patient Donda West, who is Kanye West’s mom. TMZ reports:

The Medical Board of California filed legal papers last April asking to revoke or suspend Dr. Jan Adams’ medical license because he was convicted of multiple DUIs, one in 2006, another in 2003. TMZ has also turned up a 1994 DUI conviction.

In the accusation, the Executive Director of the Medical Board states Adams "has used alcohol to the extent or in such a manner as to be dangerous or injurious to himself and others…"

Dr. Jan Adams told TMZ last night that he "did nothing wrong" in operating on Donda West.

In November of 2003, Dr. Jan Adams — the plastic surgeon who operated on Kanye West’s mom before her death — appeared on an episode of "The Oprah Winfrey Show."

According to his bio, Adams has made "countless appearances" on television — including serving as host for a show on the Discovery Channel called "Plastic Surgery: Before and After."

He also co-hosted NBC’s The Other Half with Dick Clark, Danny Bonaduce, and Mario Lopez.

The most incriminating evidence is that the surgery took twice as long as it should have, which put Donda West, who was already a risky surgical candidate at much great risk of having complications, but Dr Jan Adams maintains he did nothing wrong.

Sources tell TMZ Donda West’s operation lasted eight hours — twice as long as it should have. We’re told Dr. Jan Adams began the operation Friday morning and finished Friday evening. He then sent Ms. West home, rather than to a recovery center, which we’re told, would have been appropriate.

Several doctors at Centinela Hospital where West was taken, tell TMZ they believe the excessive amount of time it took to perform the procedure strongly suggests either something went wrong during the operation or the doctor was just too inexperienced.

We’re told she was dead the next evening at her home before paramedics arrived.

What’s more, Dr. Adams is not Board Certified with the American Board of Plastic Surgery.

The only part of this that is relevant on the day of the surgery is that the surgery itself took twice as long as is normally expected, and after what are suspected to already be complications during surgery, Dr Adams still sent Donda West home, rather than to a recovery facility, or even a hospital where she could be properly treated. Dr Adams may face a wrongful death lawsuit, and his medical license may be revoked or suspended.
