title: [Peptone stimulation of the lower esophageal sphincter in patients with reflux disease].
abstract: Twenty patients with gastroesophageal reflux disease (10 with compensated and 10 with decompensated gastroesophageal incompetence) were examined to determine if there was a correlation between the ability of physiological stimuli to tonicize the lower esophageal sphincter (LES) and the response to pentagastrin stimulation (Gastrodiagnost). The pressure of the lower esophageal sphincter as well as blood levels of the hormones/neurotransmitters gastrin, PP and VIP were determined after giving a 300 ml intragastral bolus of either 0.9% NaCl or 20% peptone solution. All patients exhibited per definitionem a positive common-cavity phenomenon on abdominal compression. Intravenous pentagastrin stimulated the LES in patients with compensated gastroesophageal incompetence (GI) but not in those with decompensated GI (p less than or equal to 0.0005). Esophagoscopy revealed a severe esophagitis in 80% of the patients with decompensated GI but in only 10% of the patients with compensated GI. Peptone stimulated the LES in patients with compensated GI (p less than or equal to 0.005) at 5, 10 and 15 minutes, pepton vs. NaCl). Neither NaCl nor peptone increased the tone of the LES in patients with decompensated GI. Peptone but not NaCl caused a significant increase of serum gastrin in all patients: there was no difference between the two groups. Neither NaCl nor peptone influenced VIP levels in peripheral blood. PP levels increased significantly in both groups following peptone. Physiological responsiveness of the LES can be inferred from the manometric data and the results of the pentagastrin test. A negative reaction to pentagastrin is associated with a loss of response to physiological stimuli.(ABSTRACT TRUNCATED AT 250 WORDS)
