OBJECTIVE: The objective of this study is to investigate the impact of ketorolac and other nonsteroidal anti-inflammatory drugs on anastomotic leakage after surgery for gastro-esophageal-junction cancer. Within the last two decades, the incidence of gastro-esophageal-junction cancer has increased in the western world and surgery is the curative treatment modality of choice. Anastomotic leakage is a feared complication of gastro-esophageal surgery, as it increases recurrence, morbidity, and mortality. Nonsteroidal anti-inflammatory drugs are widely used for postoperative pain relief. Nonsteroidal anti-inflammatory drugs have, however, in colorectal surgery, been shown to increase the risk of anastomotic leakage.

METHOD: In a historical cohort study, we investigated the impact of nonsteroidal anti-inflammatory drugs on anastomotic leakage in 557 patients undergoing surgery for gastro-esophageal-junction cancer. Data were collected from a prospective maintained database, the Danish National Patient Registry, and patient medical records. Data were analyzed using univariate and multivariate statistical models and were stratified for theoretical confounders.

RESULTS: In univariate analysis, we did not observe any difference in age, gender, tobacco exposure, or comorbidity status between patients experiencing anastomotic leakage and those without. In multivariate analysis, gender, histology, and type of anastomosis proved to affect odds ratios for anastomotic leakage. After adjustment for possible confounders, we found an odds ratio of 6.05 (95% confidence interval 2.71; 13.5) for ketorolac use and of 5.24 (95% confidence interval 1.85; 14.8) for use of other nonsteroidal anti-inflammatory drugs for anastomotic leakage during the first seven postoperative days.

CONCLUSION: In the present study, we found a strong association between the postoperative use of ketorolac and other nonsteroidal anti-inflammatory drugs and the risk for anastomotic leakage after surgery for gastro-esophageal-junction cancers.
