No extensive endoscopic studies have been performed on the prevalence and the clinical outcome of association of gastric ulcer (GU) and duodenal ulcer (DU). The present investigation, partially retrospective and partially prospective, takes into account 715 patients with active ulcer demonstrated by endoscopy, followed-up for a mean period of 3.8-years; 23 of them (3.2%) were found to have synchronous or asynchronous gastric and duodenal ulcers. The following characteristics were investigated: age of onset of both diseases, ulcer family history, cigarette and alcohol consumption, nonsteroidal anti-inflammatory drugs abuse, serum pepsinogen group I, ABO and Lewis blood groups, healing and relapse rate under H2-blocker treatment. The first diagnosis (by either X-Ray or endoscopy) was DU in 500 subjects (70%), GU in 210 (29.3%) and synchronous gastric and duodenal ulcers in 5 (0.7%). After a median period of 10 years, 2.8% of DU patients developed a GU; after 2-12 yrs 1.9% of GU patients developed a DU. The clinical and biochemical findings of our GU/DU patients suggest that the two ulcers are related by chance. In conclusion: asynchronous GU/DU patients do not seem to have a distinct disease in the large spectrum of ulcer disease. Larger studies must be planned on synchronous GU/DU with the aim of assessing whether or not it represents a particular type of ulcer disease.
