简要总结
- ERCP is a commonly performed endoscopic procedure used to treat stones and blockages of the bile duct as well as to manage leaks which occurs following laparoscopic gallbladder removal.
- Post ERCP pancreatitis (PEP) complicates 5-15% of biliary endoscopic procedures and results in considerable suffering and cost.
- Patients with acute pancreatitis are treated with fluids.
- Our aim is to assess whether prophylactic treatment with aggressive intravenous hydration prevents ERCP pancreatitis.
- In a blinded fashion patients will be randomized to aggressive intravenous versus moderate hydration during and aftere ERCP for standard clinical indications.
Our hypothesis is that prophylactic treatment with aggressive intravenous hydration protects against ERCP pancreatitis.
详细描述
1.0 BACKGROUND AND HYPOTHESES
Post endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis is defined as the development of epigastric pain radiating to the back accompanied by either an increase in the pancreatic enzymes (amylase and lipase) to greater than three times the upper limit of normal or cross sectional imaging showing inflammation of the gland. Based on length of hospitalization it is categorized as mild (2-3 days), moderate (4-10 days), or severe (>10 days). Cases complicated by hemorrhage, pseudocyst, phlegmon formation or requiring percutaneous intervention or surgery are also scored as severe.
Post ERCP pancreatitis is the leading complication of biliary endoscopic procedures and could potentially lead to considerable morbidity. The overall incidence of ERCP pancreatitis ranges from 5% in the community to 15% in centers where advanced ERCP including pancreatic interventions are performed.
Proposed mechanisms include protease and free radical mediated inflammation, abnormal sphincter of oddi pressure, and elevated pancreatic exocrine activity. Measures to prevent post-ERCP pancreatitis aim to curb these processes.
Numerous trials studying the use of various preventive therapies including octreotide and protease inhibitors have been for the most part disappointing. There have been more than twenty clinical trials examining the efficacy of somatostatin and octreotide which inhibit pancreatic exocrine stimulation. A meta-analysis of nine high quality trials of somatostatin showed that overall the medication did not reduce post ERCP pancreatitis. Gabexylate mesylate and ulnistatin which inhibit pancreatic proteases have also shown to not significantly reduce post ERCP pancreatitis. Numerous studies have also shown that corticosteroids do not diminish the likelihood of post-ERCP pancreatitis.

研究组 & 干预措施
Aggressive Intravenous Hydration Group
Patients randomized to the aggressive intravenous hydration group receive lactated ringers (LR) IV at 3 mL kg-1 hr-1 during the procedure, a 20cc/kg LR IV bolus immediately afterward, and LR IV at 3 mL kg-1 hr-1 for 8 hours following the procedure.
干预措施: Aggressive Intravenous Hydration Group (Other)
Standard Fluids Arm
Those in the control arm receive standard fluids defined as LR at 1.5 mL kg-1 hr-1 during the procedure and for 8 hours afterwards.
干预措施: Standard Fluids Arm (Other)
结局指标
主要结局
Acute Pancreatitis
时间窗: 24 hours
The primary endpoint is post ERCP pancreatitis which is defined as increased abdominal pain and a serum amylase level three times the upper limit of normal (3xULN). Increased pain will be defined as an increase in the visual analog pain score compared to the value immediately prior to ERCP
次要结局
- Serum amylase three times the upper limit of normal(24 hours)
- Increased abdominal pain(24 hours)
- Clinical volume overload(24 hours)
