IntroductionAnastomotic leakage is a serious complication after colorectal resection. Recent studies suggest that nonsteroidal anti-inflammatory drugs may increase the risk of anastomotic leakage. We investigated this association in our enhanced recovery population.Material And MethodsPatients undergoing an elective colon or rectal resection with primary anastomosis because of malignancy and treated within our enhanced recovery program were included. Univariable and multivariable logistic regression analyses were used to study risk factors for anastomotic leakage.ResultsBetween 2006 and 2013, 856 patients were included. The anastomotic leakage rate was significantly higher in the group that received nonsteroidal anti-inflammatory drugs compared to patients who did not: 9.2 vs. 5.3%, p = 0.038. This higher rate was only seen in patients receiving diclofenac: for colonic resections, 11.8 vs. 6.0%, p = 0.016; for rectal resections, 13.1 vs. 0%, p = 0.017. Only male sex (odds ratio 2.20, p = 0.005) was also independently associated with anastomotic leakage.ConclusionThe results of this study are in line with other comparable studies in the literature, showing an increased risk for anastomotic leakage with diclofenac. The use of diclofenac in colorectal surgery can no longer be recommended. Alternatives for postoperative analgesia need to be explored within an enhanced recovery program.
