BACKGROUND: No studies have examined the risk of upper gastrointestinal diseases among patients with unexplained chest/epigastric pain (UCEP) and a normal upper endoscopy. AIM: To examine the relative risk of peptic ulcer, oesophagitis, pancreatitis or gallstone in UCEP patients. METHODS: This Danish 10-year cohort study focused on UCEP patients (n = 386), diagnosed in 1992-93. Ten age- and gender-matched controls were selected per patient from Denmark's Civil Registration System (n = 3860). Kaplan-Meier analysis and Cox's regression analysis was used to calculate the risk of hospitalization for peptic ulcer, oesophagitis, pancreatitis or gallstone. RESULTS: Compared with controls, the adjusted relative risks among UCEP patients <1 and > or = 1 year after upper endoscopy were for peptic ulcer 2.0 [95% confidence interval (CI) 0.2-18.4] and 1.7 (95% CI 0.9-3.4), for oesophagitis 8.2 (95% CI 1.2-59.2) and 1.9 (95% CI 0.7-5.0), for pancreatitis 9.2 (95% CI 2.0-41.8) and 3.9 (95% CI 1.4-10.5), and for gallstone 14.1 (95% CI 5.4-37.2) and 3.3 (95% CI 1.9-5.8). CONCLUSIONS: UCEP is positively associated with all study outcomes especially in the first year after upper endoscopy, indicating that peptic ulcer, oesophagitis, pancreatitis or gallstone could be underlying early UCEP symptoms. However, the long-term association remained strong for pancreatitis and gallstone, suggesting a genuine excess risk.
