Effect of Dexketoprofene Trometamol on Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis.

Objective: To evaluate the efficacy of dexketoprofene trometamol solution following the administration of contrast agent for Endoscopic Retrograde Cholangiopancreatography (ERCP) in decreasing the rate of pancreatitis, in experimental rat model. Study Design: Experimental study. Place and Duration of Study: Faculty of Medicine, Research and Animal Laboratory of Bezmialem University, Istanbul, Turkey in January 2018. Methodology: Forty Wistar-Albino (R) male rats of 250-300g were divided into 4 equal groups. Group I underwent cannulation; group II had cannulation with saline; group III had cannulation and contrast agent; group IV had cannulation with contrast agent and dexketoprofene trometamol intra-muscular (IM). Twenty four hours following the procedure, the rats were sacrified and pancreatic tissues were examined histopathologically, with evaluation of blood levels of leukocyte, glucose, SGOT, LDH, amylase, and C-reactive protein (CRP) level. Histopathological grading of acute pancreatitis was performed using haematoxylin and eosin staining. Results: Mean levels of amylase and leukocyte were found to be significantly higher in groups II, III, IV when compared to group I (p= 0.001). CRP level was found to be highest in group III (p= 0.001). Histopathological grade of pancreatitis was found to be significantly higher in groups II, III, IV than group I (p: 0.001, 0.001, 0.028, and 0.001, respectively). Scores of edema, acinar necrosis, inflammation and perivascular infiltration of group III were higher than in group IV (p= 0.001). Conclusion: Intra-muscular administration of dexketoprofen trometamol during ERCP procedure may be beneficial in decreasing the rate of post-ERCP pancreatitis, as shown by histopathological and laboratory profile.
