    Abstract:
    Prostaglandins are presumed to have cytoprotective properties and may play a role in the pathogenesis of duodenal ulcer and its complications. To evaluate this hypothesis, 35 patients with either duodenal ulcer bleeding (18 patients) or gastric outlet obstruction (17 patients) were investigated. Biopsies were taken from gastroduodenal tissues and secretions for prostaglandin E2 (PGE2) levels. These levels were compared to those taken from the same areas during a later endoscopy. A correlation was found between the severity of the clinical endoscopic findings and PGE2 levels. Increased levels of PGE2 were found in the quiescent phase and decreased levels found during the deteriorated phase. These differences of PGE2 levels were found to be of significant value (P less than 0.002). Furthermore, the patients in which the PGE2 levels were decreased at second endoscopy needed surgery. PGE2 may, thus, be a factor in duodenal ulcer pathogenesis and its complications, and be used as a prognostic marker and guide.
