Study Overview
Brief Summary
This study compares the effect of endoscopic sphincterotomy and endoscopic papillary balloon dilation in the treatment of acute biliary pancreatitis.Participants with acute biliary pancreatitis will be randomized into either the endoscopic sphincterotomy or endoscopic papillary balloon dilation groups.Moreover, the investigators compare the results obtained from the traditional bile/blood culture and metagenomics.
Detailed Description
Early endoscopic retrograde choledocho pancreatogram with endoscopic sphincterotomy is suggested in patients with acute biliary pancreatitis to reduce complication and mortality. Retrospective study of the investigators' hospital showed that endoscopic papillary balloon dilation is safe in the treatment of acute biliary pancreatitis. However, there is no report in literature concerning about the prospective study comparing the effect of endoscopic sphincterotomy and endoscopic papillary balloon dilation in the treatment of acute biliary pancreatitis.
Moreover, the presence of infective microorganisms in the biliary and/or pancreatic ducts may play important role in both the onset and outcome of acute biliary pancreatitis. Blood or bile obtained via endoscopic means is another way to know the causative bacterium/bacteria.
However, it still need considerable period of time to get the result of the culture. Recently, next-generation sequencing technologies have been developed, which can facilitate the analysis of a large number of microorganisms in different environments and human body sites. 16S(a svedberg unit) ribosomal deoxyribonucleic acid sequence analysis and metagenomics are two effective DNA sequencing approaches, and both have been used to study uncultivated gut microbial communities.
Aims:
- To study the clinical effects of endoscopic sphincterotomy and endoscopic papillary balloon dilation in acute biliary pancreatitis.
- To compare the results obtained from the traditional bile/blood culture and metagenomics.

Inclusion Criteria
- •Patients with age ≥ 20 years and acute biliary pancreatitis concomitant with either signs of acute cholangitis or bile duct obstruction will be enrolled in the study. They will be randomized into two treatment groups (sphincterotomy vs. balloon dilation).
- •Inclusion Criteria:
- •Patients diagnosed with acute gallstone pancreatitis and fulfill any two items from a to c, plus one item in d, and e:
- •abdominal pain typical of pancreatitis;
- •elevation of serum amylase and/or lipase up to three times above normal;
- •imaging studies (abdominal ultrasound or abdominal computed tomography) showed evidence of pancreatitis
- •common bile duct stones, acute cholangitis (Charcot's triad), total bilirubin (total bilirubin)> 4mg / dL, bile duct dilatation (diameter> 6mm with intact gallbladder, or> 10mm when the gallbladder has been removed) plus total bilirubin 1.8 ~ 4mg / dL;
- •exclude other causes of acute pancreatitis.
Exclusion Criteria
- •septic shock
- •serious coagulopathy (international normalized ratio 1.5, partial thromboplastin time greater than twice that of control, platelet count <50 x 1000 / Cumm)
- •malignant tumors of the biliary and pancreatic tract
- •severe cardiovascular or mental illness which can not cooperate with the exam and treatment;
- •pregnant women
- •patient who had ever received surgery or endoscopic treatment for biliopancreatic tract
Arms & Interventions
Endoscopic papillary balloon dilation
For EPBD group, after selective cannulation of the common bile duct by the catheter, cholangiography will be performed to confirm the diagnosis of bile duct pathology. A 0.025-0.035-inch guidewire will then be inserted into the bile duct through the catheter. A dilating balloon (The controlled radial expansion (CRE) balloon dilation catheter, CRE balloon 5.5 cm (centimeter) in length, 1-1.2 cm/1.2-1.5 cm/1.5-2.0 cm in diameter) will be passed via the pre-positioned guidewire into the bile duct. Using fluoroscopic and endoscopic guidance, the balloon will be inflated with contrast medium up to the optimal size and duration (normally 5min (minutes)) after the waist on the balloon disappeared according to the patients' condition and tolerance.
Intervention: Endoscopic papillary balloon dilation (Procedure)
Endoscopic sphincterotomy
For EST group,endoscopic sphincterotomy(EST) will be done as large as possible with a pull type sphincterotome (The TRUEtome, Biliary sphincterotomy sphincterotome, Single-use sphincterotome CleverCut2V)
Other interventions: surgical intervention, endoscopic stenting, percutaneous transhepatic cholangiogram with balloon dilation
Intervention: Endoscopic sphincterotomy (Procedure)
Outcomes
Primary Outcomes
Complete removal of common bile duct stones
Time Frame: one year
Successful bile duct clearance was defined as complete if the final cholangiogram revealed no more filling defects.
Secondary Outcomes
- Evaluation of adverse events(One week)
