Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Endoscopic papillary balloon dilatation (EPBD) is an alternative technique developed to achieve the same purpose as EST but preserving Oddi's sphincter' function partially, and more than that, EPBD is easy to grasp for endoscopist. By using a columnar balloon, Oddi's sphincter can be expanded without direct transection, and the temporary relaxation of Oddi's sphincter makes it possible to remove the stones and the rest of the procedures as well. Removing common bile duct stone by EPBD was firstly reported in 1982 and proved to be safe and efficient. However, clinical observations have been found that simple EPBD has a higher incidence of developing acute pancreatitis after ERCP, especially in patients with intact papilla. The speculated reason for high post-ERCP pancreatitis (PEP) rate might be pancreatic duct orifice edema resulted from inadequate destroy of Oddi's sphincter during a balloon dilatation, leading the pancreatic duct obstructed and high ductal pressure afterward. Retrospective study has indicated the PEP rate of post-EPBD by 10% which was considered slightly higher than ordinary EST before a new modified method has been introduced by a small EST prior to EPBD. Currently small EST plus EPBD has been increasingly used in clinical and proven to be an effective treatment for improving the success rate of the common bile duct stone removal, preserving Oddi's sphincter function and lowering long-term complications.
Dedicate practitioners conducted many kinds of studies about reducing post-ERCP complications, and nowadays, some of them focus on the dilation time of EPBD which would be suspected as the key point of the issues. Nonetheless, more institutes are willing to join in EPBD research as the universal concerns for post-ERCP complications increases, no common agreements achieved at present.
From some prospected data, we might see confused results. Slowly inject balloon with a contrast agent and keep dilating for 1-2 minutes, until 15 seconds after the image of papilla and balloon waist disappeared is able to get the same stone removal rate as regular procedure does, and a slower balloon filling performance is helpful to protect the Oddi's sphincter function and reduce post-ERCP complications. However, other studies conclude there are no difference no matter in stone removal rate or post-ERCP pancreatitis instead of blood amylase, in which arms are 20 seconds compared 60 seconds and 30 seconds compared 60 seconds. Interestingly, there is another inspiring randomized controlled trial (RCT) study which prolong the dilation time up to 5 minutes. The author figured that PEP rate of five minutes group is smaller than that of the 1-minute group as well as stone removal.
Few studies concerning the optimal duration time of EPBD which is very important to patients' safety and maximum utilization of the easier handled EPBD procedure compared to EST. Therefore this large volume multicenter prospective randomize control study targets on how different EPBD duration management affect the complications after ERCP which attempts to discover a promising method for safe therapy in common bile duct stones.

Study Groups

0" group
After a small sphincterotomy was performed, a controlled radial expansion (CRE) balloon (diameter 8, 9, 10, 11, 12, 13.5, 15; Boston Scientific) was chosen according to the diameter of bile duct. It was placed across the papilla orifice and then gradually filled with diluted contrast in 15 seconds. When the waist disappeared, the balloon was deflated immediately. The stones were then retrieved by a basket or retrieval balloon. Mechanical lithotripsy was used if necessary.
