OBJECTIVE Limited evidence is available on rebleeding due to nonsteroidal anti‐inflammatory drugs (NSAIDs)‐induced enteropathy. Previous studies have primarily analyzed endoscopic findings. Therefore, there is a need to evaluate their clinical implications for patients. This study aimed to evaluate the rebleeding rate and its related risk factors in patients with NSAIDs‐induced enteropathy. METHODS Of 402 patients with obscure gastrointestinal bleeding who were evaluated with capsule endoscopy, 49 were diagnosed with NSAIDs‐induced enteropathy. The clinical characteristics of the patients were retrospectively analyzed. The Charlson comorbidity index was used to stratify the comorbidities. For patients who used additional drugs that influenced their tendency to bleeding, the odds ratio was calculated and used for a quantitative comparison. RESULTS The rebleeding rate in patients with NSAIDs‐induced enteropathy was 20.4%, within a mean duration of 23.4 months. Age ≥65 years (hazard ratio [HR] 8.628, 95% confidence interval [CI] 1.152–64.625), no additional use of mucoprotective agents (HR 11.712, 95% CI 1.278–76.098) and the continuation of NSAIDs after the first bleeding episode (HR 9.861, 95% CI 1.395–98.344) were independently related to rebleeding due to NSAIDs‐induced enteropathy. The underlying comorbidities, drug‐related rebleeding risk scores and therapeutic use of proton pump inhibitors were not significantly different ( P = 0.209, 0.212 and 0.720, respectively). CONCLUSIONS Approximately one‐fifth of patients with NSAIDs‐induced enteropathy showed rebleeding within 2 years. A careful long‐term follow‐up should be offered to elderly patients with NSAIDs‐induced enteropathy who need continuous NSAID treatment without the additional use of mucoprotective medications.
