NEW YORK (AP) _ A plastic surgery resident's clandestine, unsupervised ``tummy tuck'' on a family friend led to his dismissal from a hospital just one week before his training would have ended.

The May firing, reported Wednesday in The New York Observer, was confirmed in a terse statement by Columbia-Presbyterian Medical Center.

Hospital spokeswoman Susan Parker would not answer questions about whether other Columbia-Presbyterian residents conducted similar unauthorized cosmetic surgery, as the Observer alleged.

The Observer reported that Dr. James A. Brady, a fifth-year plastic surgery resident, performed the abdominoplasty three months ago in the evening, using a hospital facility and a local anesthetic.

State law requires that residents have a senior supervising doctor present and that medical records be kept of the procedure. The newspaper reported that neither requirement was followed.

The operation was reportedly discovered when the patient came down with an infection and went to another hospital.

The newspaper said attempts to reach Brady for comment were unsuccessful. The Health Department would not confirm the name of the physician for The Associated Press.
