Depends on surgery.
The length of recovery depends on many factors, but the most important would be the type of antireflux surgery you have.
Typically patients undergoing laparoscopic surgeries, such as a nissen or toupet, spend 1 night in the hospital and recovery is 1-2 weeks. The new transoral surgery, tif, is typical 1 week recovery. But remember that some people recover from surgery faster than others.
