Ulcer recurrence among Filipino patients: clinical profile and risk factors.

Patients with endoscopic diagnosis of gastric and/or duodenal ulcers who eventually had endoscopic confirmation of ulcer healing after any anti-ulcer medication were entered in a 3 year study to determine ulcer recurrence rate, onset of ulcer recurrence and factors associated with ulcer recurrence. Patients from two participating centres who are not on any maintenance treatment had endoscopic examinations at 3, 6 and 12 months after ulcer healing or at any time of symptom recurrence. There were 144 patients entered into the study.
