Abstract

Few studies address the proper extent of the preoperative testing in patients referred fur consideration of antireflux surgery. Our aim was to perform a thorough gastroesophageal evaluation and determine it's influence on the therapeutic decisions of such patients. We evaluated 107 consecutive patients in a combined GI/Surgery clinic for severe or refractory gastroesophageal reflux. The patients had an EGD, esophageal manometry, and 24‐h ambulatory esophageal pli monitoring. Only patients with gastric symptoms had gastric testing. Nineteen patients were excluded, 12 refused further evaluation and seven were felt to be unfit for antireflux surgery because of medical or psychological reasons. Eighty‐eight patients completed the required studies. Fifty‐four patients (61%) had typical reflux symptoms and erosive esophaghis on EGD. All these patients had an abnormal pH study. Five of the 34 patients without esophagitis had a normal pH study and did not have surgery. Ten patients had poor peristalsis by esophageal manometry prompting a subtotal fundoplication. One patient had severe delayed gastric emptying, requiring pyloroplasty in addition to the fundoplication. Eighty of 83 patients had good or excellent surgical results. EGD and esophageal manometry are indispensable in the preoperativc evaluation. Manometry may identify abnormalities altering surgical decisions in roughly 10% of patients. Routine ambulatory esophageal pH monitoring is of marginal benefit, except in patients without esophagitis or in those patients where the diagnosis is in doubt. Clinically significant gastric abnormalities are rare, and routine testing of gastric function is not indicated.
