ketorolac use and the risk of anastomotic leak after colorectal surgery.

“This meta-analysis included seven studies with 400,822 patients. Our results demonstrated that ketorolac administration after surgery increases the risk of anastomotic leak [OR = 1.41, 95% CI: 0.81–2.49, Z = 1.21, P = 0.23].”


“Anastomotic leak is a serious complication that occurs after colorectal surgery, which can lead to increased morbidity and mortality. Non-selective NSAIDs (such as ketorolac) may affect the healing of the intestine by inhibiting the action of cyclooxygenase. NSAIDs have been shown to weaken granulocyte function, which is an essential part of the acute phase of wound healing. NSAIDs may also inhibit epithelial cell migration and mucosal recovery, which are important in the pathophysiology of intestinal ulcer healing. These findings suggest a potential biological mechanism that may explain the association identified in this study.”
