Which type of doctor performs a stomach hernia surgery?

Gastric hernia: A gastroenterologist or a general surgeon trained in the techniques.

General Surgeon: One of the most common operations performed by general surgeons are hernia repairs. There are many different techniques based upon the type of hernia, the training and experience of the surgeon, and the unique features of each patient: these are not "one size fits all" operations. Happily, most hernia operations are low-risk, out-patient procedures.
