A Melbourne Coroner says an inquiry into the death of a 26-year-old woman who died after liposuction surgery will focus on her post-operative care.

Lauren James died in January 2007 just three days after liposuction to her legs and buttocks.

Surgeon Tam Dieu told the Coroner's Court that he no longer performs liposuction fearing his mental scars from Lauren James' death are too great to conduct that type of surgery.

Dr Dieu told the court today that his liposuction was not to blame for Ms James' death.

He said he qualified in plastic surgery at Monash University and had performed more than 200 liposuctions prior Ms James' death.

He told the court the operation itself was not at fault and Coroner Paresa Spanos said her investigation will focus on the level of post-operative care.

The inquiry is continuing.
