Nonsteroidal anti-inflammatory drug (NSAID) prescribing after gastrojejunostomy: A preventable cause of morbidity

Study findings showing an association between nonsteroidal anti-inflammatory drug use and marginal ulcer, a significant cause of morbidity after gastrojejunostomy, have been inconsistent. This study aimed to evaluate this relationship in large cohort. This retrospective cohort included adult patients with a history of gastrojejunostomy documented between 2004 and 2023. The electronic medical record was queried for nonsteroidal anti-inflammatory drug prescriptions, marginal ulcer diagnosis, and comorbidities. Multivariable logistic regression was performed to assess the association between marginal ulcer and nonsteroidal anti-inflammatory drug exposures, controlling for smoking, Helicobacter pylori history, acid-suppressing therapy, diabetes, age, and sex. During the study period, 6,888 patients with a history of gastrojejunostomy were identified, of whom 45.2% (n = 3,115) of patients were exposed to an nonsteroidal anti-inflammatory drug and 10.12% (n = 697) developed a marginal ulcer. On multivariable analysis, the risk of marginal ulcer was found to be dose-dependent, with increasing odds of marginal ulcer with an increasing number of nonsteroidal anti-inflammatory drug exposures from odds ratio 1.67 (95% confidence interval, 1.37–2.02) with 1–2 nonsteroidal anti-inflammatory drug exposures to odds ratio 2.42 (95% confidence interval, 1.79–3.24) with >8 nonsteroidal anti-inflammatory drug exposures. Acid-suppressing therapy was found to be protective (odds ratio, 0.61; 95% confidence interval, 0.52–0.73). Over the last decade, the number of nonsteroidal anti-inflammatory drugs prescribed to patients with gastrojejunostomy has significantly increased from 15.87 prescriptions per 1,000 patients per year to 531.02 per 1,000 patients per year (R2 = 0.91, P < .001). Marginal ulcer after gastrojejunostomy is associated with nonsteroidal anti-inflammatory drug prescriptions in a dose-dependent manner. Although acid-suppressing therapy appears protective for marginal ulcer, quality improvement efforts should focus on diminishing nonsteroidal anti-inflammatory drug prescribing in this population.
