Asymptomatic duodenal ulcers occurring during maintenance treatment with ranitidine

Fifty-seven patients who developed asymptomatic recurrence of duodenal ulceration during maintenance treatment with ranitidine were followed up to assess the risk of developing symptoms or complications of ulcer disease. The risk of development of symptomatic ulcer recurrence was 4% in the first year of follow-up during continuous maintenance treatment, irrespective of whether or not the asymptomatic ulcer had been actively treated (by doubling the dose of ranitidine used for maintenance therapy). The asymptomatic duodenal ulceration during maintenance treatment did not predispose to complications such as haemorrhage or perforation. It seems, therefore, that patients receiving maintenance treatment for duodenal ulceration do not require endoscopic re-examination unless symptoms have recurred, because the asymptomatic recurrences of duodenal ulceration occurring during maintenance treatment are clinically benign, usually heal spontaneously if maintenance treatment is continued, and do not require active medical intervention.
