Notizen: Abstract Aim of the study was to analyze gastricdistension with water in H. pylori-positive and-negative dyspeptic patients and normal subjects and thecorrelation with symptoms. Twenty dyspeptic patients and 19 normal subjects were studied. H. pylori wasdetermined in each dyspeptic patient with the rapid ureatest at endoscopy. Gastric distension was evaluated byreal-time ultrasonography with the ingestion of stepwise-increasing amounts of water up toa total of 600 ml. During distension, the symptom scorewas evaluated as well. The proximal stomach wassignificantly smaller in dyspeptic patients than in healthy controls, at 100-600 ml water (P 〈0.01). A larger distal stomach was observed at 500 and600 ml of water (P 〈 0.01). The score of bloating andfullness was greater in dyspeptics than in controls at 300 and 600 ml of water distension.The symptoms score was linearly correlated with proximaland distal gastric measurements in dyspeptic patientsand in controls. No significant difference was found in dyspeptic patients regarding theH. pylori status. In conclusion, dyspeptic patients showa defective adaptation of the whole stomach to waterdistension and an increased symptom perception score as compared to controls. H. pyloriinfection does not seem to be a determining factor inthese observed findings.
