|Acute Biliary Pancreatitis||Procedure: Endoscopic papillary balloon dilation Procedure: Endoscopic sphincterotomy||Not Applicable|
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.
- 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.
Methods: Beginning from Jan 2016, 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. Participants will be randomized into either the endoscopic sphincterotomy or endoscopic papillary balloon dilation groups. The treatment effects and safety of both groups will be compared. The primary endpoint is the relative successful rates of retrieval of common bile duct stones of both groups. The secondary endpoint is the frequency of use of mechanical lithotripter, other drainage procedures, complication and mortality, as well as the number of treatment sections.
Besides blood culture exam, bile will be aspirated by placing a single-use, 5-French, standard catheter (after guide-wire cannulation) into the bile duct before the injection of contrast agent for endoscopic retrograde cholangiopancreaticography. Approximately 10 mL of bile will be collected and transferred in a sterile tube. Half of the bile obtained will be transported to the microbiology laboratory in blood culture bottles and in an anaerobic transport system. Bacteria will be cultured and identified according to the standard protocol used in our clinical microbiology laboratory. Another half of the bile specimen will be sending for metagenomic study. Finally, investigators will try to compare the results obtained from the traditional bile culture /blood culture and metagenomics, and to understand the effects of infective microorganisms in the biliary and/or pancreatic ducts on the acute biliary pancreatitis. In addition, investigators want to find out the best means of early and accurate diagnosis of the pathogen responsible for the infection.

Experimental: 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.
Procedure: Endoscopic papillary balloon dilation
treatment of endoscopic papillary balloon dilation
Other Name: EPBD
Active Comparator: 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
Procedure: Endoscopic sphincterotomy
treatment of endoscopic sphincterotomy
Other Name: EST
- 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.
- Evaluation of adverse events [ Time Frame: One week ]Adverse events were recorded according to the definitions and grading systems from the consensus of an American Society of Gastrointestinal Endoscopy Workshop. (P. B. Cotton, G. M. Eisen, L. Aabakken et al., "A lexicon for endoscopic adverse events: report of an ASGE workshop," Gastrointestinal Endoscopy, vol. 71, no. 3, pp. 446-454, 2010.)
