WILMINGTON, Del. (AP) - A Delaware man who says he awoke from a colonoscopy to find he was wearing pink women's underwear is suing a surgical center.

Andrew Walls of Dover filed the civil lawsuit in New Castle County Superior Court against the Delaware Surgery Center on Friday. It seeks unspecified damages.

A spokeswoman for the surgery center declined to comment on the case.

Walls' attorney, Gary Nitsche, wrote in the lawsuit that his client suffered severe emotional stress and mental anguish after waking up from a colonoscopy on Oct. 12, 2012, to find he was wearing pink women's underwear. Walls says he had not been wearing the underwear before being given anesthesia for the procedure.

The News Journal reports that Walls also claims he's lost wages and earning capacity over the incident.
