Benign stricture of the oesophagus: role of non-steroidal anti-inflammatory drugs.

The medication history of patients presenting with benign oesophageal stricture is compared with an age and sex matched control population selected from the community. Fifty five out of 151 consecutive admissions to a dysphagia clinic were found to have benign oesophageal stricture. Twenty six out of 53 (49%) had been prescribed non-steroidal anti-inflammatory drugs in the year preceding their clinic appointment. Ten patients (19%) had been prescribed other drugs implicated in oesophageal disease over the same period. In the control population, 20 out of 165 (12%) had been prescribed non-steroidal anti-inflammatory drugs, and 31 out of 165 had been prescribed 'other' drugs in the preceding year. The difference between numbers on non-steroidal anti-inflammatory drugs in the patient and control groups was highly significant (X2 = 23.87, p less than 0.1%). This study has shown an association between the prescribing of non-steroidal anti-inflammatory drugs and benign stricture of the oesophagus.
