Levaquin and pancreatic cancer

My husband was having gastrointestinal problems for about a week. The PA at his primary care physician's office prescribed Levaquin for 7 days. Blood taken ½ hr after Levaquin started showed liver levels to be a little high. By the 3rd or 4th day my husband was jaundiced. Blood taken on the 6th day revealed liver levels dramatically higher. He is still jaundiced and liver levels are still at the higher level. Had ERCP procedure, CT scan of abdomen and MRCP, but no conclusions other than stricture of bile duct and possibly pancreatic cancer, although a mass has not been seen on any film. Has this happened to anyone else on Levaquin? Doctors want to try ERCP again and if that does not work then the Whipple Procedure which is major surgery to remove a possible pancreatic cancer that they have not seen.
