"Chaz and Roger Ebert are grateful to everyone for the continued prayers and concern," lawyer Eliot Ephraim said Friday. "The surgery went well, and the Eberts look forward to giving you more good news about Roger's recovery in the days to come."
Ephraim did not give further details.
Ebert has been a film critic at the Chicago Sun-Times for more than 40 years.
He has undergone a series of operations, including the removal of a growth on his salivary gland and a tracheostomy, a procedure that opens an airway through an incision in the windpipe, that left him unable to speak.
