BACKGROUND: Gastric function in trauma patients is poorly understood. In animals, shock causes gastric luminal alkalinization and bile reflux. In trauma patients, studies of stress gastritis prophylaxis demonstrated with continuous gastric pH monitoring that the stomach became alkaline even without antisecretory therapy. Therefore, we hypothesized that trauma patients have an ...

BACKGROUND/AIMS: We simultaneously examined the reservoir function of the stomach as well as emptying by one single assessment for gastric emptying, and investigated their association in patients with functional dyspepsia (FD). Next, we examined the interaction between the association and abdominal symptoms. METHODOLOGY: Sixty-one FD patients according to the Rome ...

Although patients with functional dyspepsia complain of epigastric symptoms, the relation between these symptoms and gastric motility remains controversial. There are few reports on the clinical course of functional dyspepsia, including changes in gastric motility, observed over a considerably long period. We conducted a study to examine association between changes ...

Multiple endocrine neoplasia type 1 (MEN1) patients frequently develop Zollinger-Ellison syndrome (ZES). These patients can develop proliferative changes of gastric enterochromaffin-like (ECL) cells and gastric carcinoids (ECL-cell tumors). ECL-cell changes have been extensively studied in sporadic ZES patients and can be precursor lesions of gastric carcinoids, but little is known ...

Disturbed gastric contractility has been found in manometric studies in patients with gastro-oesophageal reflux disease (GORD), but the pathophysiological role of this abnormality is unclear. We aimed at assessing postprandial gastric antral contractions and its relationships with gastric emptying and gastro-oesophageal reflux in GORD patients. Fasted GORD patients (n = ...

BACKGROUND: The pathogenesis of multiple organ failure (MOF) in trauma patients may involve the gastrointestinal tract, but its exact origins remain elusive. In a prospective study, the gastric fluid of major torso trauma patients was examined for evidence of duodenogastric reflux and potential gastric injury, and was compared with patient ...

BACKGROUND: Whether mucosal inflammation affects gastric motility in patients with functional dyspepsia (FD) is controversial. Few reports discuss gastric motility in relation to histologic gastritis. We examined the relation between gastric motility and histologic gastritis in Japanese patients with FD. METHODS: Subjects were 198 patients examined by ultrasonography (US) and ...

To investigate the effect of obesity on open gastrectomy with D2 lymph-node dissection. Between January 2005 and March 2007, 100 patients with preoperatively diagnosed gastric cancer who underwent open gastrectomy with D2 lymph-node dissection were enrolled in this study. Of these, 61 patients underwent open distal gastrectomy (ODG) and 39 ...

Gastric acid plays an important part in the prevention of bacterial colonization of the gastrointestinal tract. If these bacteria have an ability of hydrogen (H2) fermentation, intraluminal H2 gas might be detected. We attempted to measure the intraluminal H2 concentrations to determine the bacterial overgrowth in the gastrointestinal tract. Studies ...

There is consensus on investigating older patients presenting with or without alarm symptoms and/or risk factors, and irrespective of their Helicobacter pylori status. Remaining patients with uninvestigated dyspepsia, however, represents a 'grey' population for whom no clearly defined guidelines have been delineated. Physicians often struggle with the decision of whether ...

BACKGROUND: Gastrointestinal (GI) symptoms are common in patients with chronic renal failure (CRF). We have previously demonstrated that patients with predialysis end-stage renal disease showed a high prevalence of GI symptoms and gastric hypomotility, and that gastric hypomotility appears to be an important factor in generating GI symptoms. However, it ...

Gastric volvulus was first described by Berti in 1966. Whereas acute gastric volvulus is very rare, chronic gastric volvulus on the other hand is being diagnosed with increasing frequency. This is attributed to the liberal use of barium meal for the evaluation of infants and children with repeated attacks of ...

The treatment goals for patients with gastroparesis are to control symptoms; to correct fluid, electrolyte, and nutritional deficiencies; and to identify and treat the underlying cause of gastroparesis. For mild symptoms, dietary modifications and a low-dose antiemetic and/or prokinetic agent might provide satisfactory control of symptoms. Dietary treatments include decreasing ...
