Duodenal, prepyloric, and combined duodenal/prepyloric ulcer disease: three distinct entities of juxtapyloric ulcer disease?
One hundred and seven patients with long-standing and severe chronic juxtapyloric ulcer disease were classified in accordance with the location of the present ulcer and previous ulcers into 1) pure duodenal (DU), 2) pure prepyloric (PU), and 3) combined duodenal/prepyloric (DU/PU) or prepyloric/duodenal (PU/DU) ulcer disease. In a prospective follow-up study over a 3-year period after parietal cell vagotomy (n = 39) or during continuous treatment with cimetidine (n = 62) patients with DU had recurrent ulcers located exclusively to the duodenal bulb and patients with PU, exclusively to the prepyloric region. In patients with DU/PU and PU/DU recurrent ulcers occurred on either side of the pylorus. Basal acid and basal pepsin outputs were higher and bile acid in gastric juice was lower in patients with DU than in those with PU. There are a considerable number of patients who possess features of both duodenal and prepyloric ulcer disease. The clinical outcome of both continuous cimetidine treatment and vagotomy in these patients (DU/PU and PU/DU) was less satisfactory than in pure DU. All patients presenting with active DU should therefore be investigated for evidence of previous prepyloric ulceration.
