Abstract
INTRODUCTION: There is growing evidence indicating the aggressive intravenous fluid resuscitation (IVFR) can decrease the rate of pancreatitis; however, to the best of our knowledge it has not been well studied in a post-endoscopic retrograde cholangiopancreatography (post-ERCP) setting. AIM: To compare the effects of aggressive IVFR and rectal indomethacin (RI) in preventing pancreatitis after ERCP. MATERIAL AND METHODS: This is a double blind randomised controlled clinical trial on 186 patients undergoing ERCP in Ahvaz, Iran. The inclusion criteria were ERCP for standard clinical indications such as choledocholithiasis, bile duct leak, and biliary obstruction. The IVFR group (n = 62) received a bolus of 20 ml/kg of body weight lactated Ringer's solution (LRS) immediately after ERCP, followed by 3 ml/kg/h maintenance for 8 h. The RI group (n = 62) received 50 mg rectal indomethacin immediately before procedure and 12 h after ERCP. The control group (n = 62) did not receive any treatment. RESULTS: Post-ERCP pancreatitis in IVFR, rectal indomethacin, and control groups occurred in 8 (12.9%), 16 (25.8%), and 20 (32.3%) patients (p = 0.036). Pancreatic pain was reported in 13 (21%), 21 (33.9%), and 27 (43.5%) patients in the IVFR, RI, and control group (p = 0.046). The serum amylase level increased over 24 h after intervention in all three groups. The mean serum amylase level 8 h after intervention in the IVFR patients was lower than the RI and control groups. CONCLUSIONS: Intravenous fluid resuscitation with LRS was more effective in preventing post-ERCP pancreatitis in comparison to the rectal indomethacin and control group.
