Which doctors/hospitals in san francisco bay area perform most hiatal hernia surgeries? Is laparoscopic best for 83 yr women-stomach is protruding

Yes. I am not familiar with the hospitals/doctors in the bay area. However, i can comment on then 2nd part of your question. Yes, if there are no other contraindications laparoscopy or even robotic surgery is better than open surgery especially for hiatal hernia in an 83 year old. Quicker recovery, shorter hospital stay, less pain, less risk of infection.
UCSF. The university of california sf group has the most experience.
