Hi. Thanks for your query, albeit short and specific. Noted the history and understood the concerns. To answer your first question, the esophageal manometry is the tests which measures the pressure within the esophagus at different times. Ph tests is done to see whether the stomach acid is being refluxed into the esophagus. The recovery time after any surgery depends upon the disease and disorder, nature of surgery, materials used, your body s healing properties due to any other associated problems like diabetes and soon. Hence the time of recovery after hiatal hernia surgery depends upon many a factors. Para-esophageal hernia can be managed laparoscopically and depends upon the expertise of the operating Surgeon.
