Other procedures associated with ERCP include the trawling of the common bile duct with a basket or balloon to remove gallstones and the insertion of a plastic stent to assist the drainage of bile. [11] Also, the pancreatic duct can be cannulated and stents be inserted. The pancreatic duct requires visualisation in cases of pancreatitis.
They are inserted at the time of ERCP, a procedure that uses endoscopy and fluoroscopy to access the common bile duct. The bile duct is cannulated with the assistance of a guidewire and the sphincter of Oddi that is located at its base is typically cut. A wire is kept in the bile duct, and the SEMS is deployed over the wire in a similar fashion ...
Biliary endoscopic sphincterotomy is a procedure where the sphincter of Oddi and the segment of the common bile duct where it enters the duodenum are cannulated and then cut with a sphincterotome, a device that includes a wire which cuts with an electric current (electrocautery). [1]
This procedure is performed during an endoscopic retrograde cholangiopancreatography (ERCP). The cystic duct is cannulated and a plastic stent is deployed to relieve the blockage and allow for drainage. ET-GBD can be considered when the patient is already undergoing an ERCP for another medical condition (i.e. choledocholithiasis).
If the jaundice is very high, the surgeon may choose to decrease jaundice before surgery by doing a procedure called endoscopic retrograde cholangiopancreatography (ERCP) and stenting. In this, a plastic or metallic tube (stent) is placed in the bile duct, which is blocked by the tumour, and opens it up from inside.
Choledochoduodenostomy (CDD) is a surgical procedure to create an anastomosis, a surgical connection, between the common bile duct (CBD) and an alternative portion of the duodenum. [1] In healthy individuals, the CBD meets the pancreatic duct at the ampulla of Vater, which drains via the major duodenal papilla to the second part of duodenum. [2]
The benefit of ERCP is that it can be utilized not just to diagnose, but also to treat the problem. During ERCP the endoscopist may surgically widen the opening into the bile duct and remove the stone through that opening. ERCP, however, is an invasive procedure and has its own potential complications.
Endoscopic stenting is a medical procedure by which a stent, a hollow device designed to prevent constriction or collapse of a tubular organ, is inserted by endoscopy. They are usually inserted when a disease process has led to narrowing or obstruction of the organ in question, such as the esophagus or the colon .
