The doctor involved in hundreds of possibly suspect colonoscopies at the Lakeshore General Hospital has run into trouble before.

The Quebec College of Physicians had stripped the doctor of his licence for two months in 2009 for incomplete files after his surgeries.

They still won't name him because of privacy and legal issues.

Because of the colonoscopy recall, the College has now banned him from performing certain procedures including colonoscopies and surgeries.

But Jean-Pierre Ménard, a lawyer specialized in medical issues, said they don't know the extent or length of that ban. He said the recall of hundreds of colonoscopies raises questions about how closely the doctor was followed to avoid a repeat incident.

"Normally, when a doctor has a pattern of practice that could have not been in compliance with the standard of care, normally, he has to be attended up to the time everything is corrected and to make sure the public is properly protected," Ménard said.

The Lakeshore General said there's a possible class action lawsuit so it wouldn't comment on the doctor's past sanctions.

The hospital announced earlier this week that almost 700 colonoscopies performed between 2009 and 2012 may have to be redone because they were incomplete, possibly resulting in misleading clean bills of health.
