Risk of ulceration with long-term indomethacin: endoscopic and histological changes in upper gastro-intestinal mucosa.
Twenty patients taking long-term indomethacin were chosen for the study because all had a normal endoscopic examination; biopsies, however, from the oesophagus, gastric antrum and duodenal bulb revealed histological inflammation in all patients in at least one site. After 8 weeks during which indomethacin therapy was continued, a further endoscopy revealed lesions in 5 patients--peptic ulcer in 3 and erosions in 2--but only 1 of these had any change in gastro-intestinal symptoms. Irrespective of whether mucosal lesions are seen on endoscopy in patients established on non-steroidal anti-inflammatory drug therapy, they remain in danger of developing both ulcers and erosions which are likely to be asymptomatic. At no time can one justifiably feel this patient group is not at risk of peptic ulceration.
