What tests should be run before considering a nissen fundoplication to manage severe, chronic gerd?

Hiatal hernia & GERD: An upper endoscopy can reveal a hiatal hernia which may be readily amendable to surgical correction via nissen fundoplication. An upper GI study, ct scan & ultrasound may or may not be needed as egd is usually capable of identifying hiatal hernia. Endoscopic hiatal hernia repair is another procedure one can consider for this problem. H. Pylori should be tested for and eradicated.

See below: Need egd, esophageal manometry and 24hr ambulatory ph monitoring.

GI series: I upper gastrointestinal barium x ray series to look for areas of narrowing or twists that could be causing gerd should be done. There are other tests that can measure stomach emptying like nuclear medicine scans. But the upper GI series with small bowel follow thru should definitely be done.

Several: The work up for surgery for gerd includes an exam by the surgeon, an upper endoscopy preferably by the surgeon, possibly a test to measure how much acid is coming up, and an esophageal manometry which tests the function of the esophagus. Sometimes an x-ray UGI is also done.
