入选标准

  • Adult patients (18-75 years old).
  • Men and women.
  • Patients with gastroparesis.

排除标准

  • Patients will be excluded from the study if symptoms are thought to represent an organic disorder (e.g., peptic ulcer disease, hepatitis, pancreatitis, inflammatory bowel disease, a known malignancy, radiation-induced injury, an active infection, vasculitis, celiac disease), GERD, esophagitis, eosinophilic esophagitis or H. pylori.
  • Patients with uncontrolled diabetes mellitus (hemoglobin A1C > 10).
  • Patients with prior surgery to the esophagus, stomach or duodenum.
  • Patients taking opioids, steroids, anti-histamines, immunosuppressive agents, NSAIDs, or mast cell stabilizing agents within the prior 3 months.
  • Patients currently prescribed aspirin or aspirin regimens for other clinical reasons.
  • Patients with known allergies to lactulose: mannitol will be excluded.

结局指标

主要结局

Assess duodenal epithelial tight junction structure in GP patients using confocal laser endomicroscopy.

时间窗: through study completion, approximately 3-4 days

次要结局

  • Assess small intestinal permeability using the lactulose:mannitol urinary excretion test.(through study completion, approximately 3-4 days)
  • Quantitate different duodenal cell types (e.g., mast cells (CK117), eosinophils, enterochromaffin, intraepithelial lymphocytes (IELs) and CCK-containing cells) in patients with GP using biopsies from both the D1 and D2 duodenal segments.(through study completion, approximately 3-4 days)
  • Measure serum levels of immune markers (e.g., IL-1,4,6,10,12,13,18; zonulin, CRP, TNF-alpha, tryptase,) in GP patients and compare to healthy controls.(One time measurement)
  • Assess the relationship of GP symptoms to intestinal permeability, using validated questionnaires, and to histopathological changes.(through study completion, approximately 3-4 days)
