Joan Rivers' cause of death revealed: report

Posted on

The New York City medical examiner’s office has confirmed Joan Rivers’ cause of death to be complications due to surgery.

As we know, Rivers died on Sept. 4 after entering Yorkville Endoscopy for an outpatient procedure with her gastroenterologist, Dr. Lawrence Cohen, who has since stepped down. Rivers was then rushed to Mount Sinai hospital.

And according to the Hollywood Reporter, Rivers’ cause of death was a lack of oxygen to her brain.

“OCME [Office of the Chief Medical Examiner] has completed its investigation. The cause of Ms. Rivers’ death is anoxic encephalopathy due to hypoxic arrest during laryngoscopy and upper gastrointestinal endoscopy with propofol sedation for evaluation of voice changes and gastroesophageal reflux disease. The manner of death is therapeutic complication,” spokeswoman Julie Bolcer said in a statement to THR. “The classification of a death as a therapeutic complication means that the death resulted from a predictable complication of medical therapy.”
