Biliary Tract & Pancreas; Four Cases of Choledochocele Diagnosed by Endoscopic Retrograde Cholangio: Pancreatography(ERCP) and Treated with Endoscopic Sphincterotomy(EST)
Abstract
- Choledochocele is a kind of choledochal cyst and represents a prolapse or herniation of the intramural segment of the distal common bile duct into the duodenal lumen. It is rare congenital anomaly and, easlily overlooked due to non-specific clinical symptoms, signs, and non-characteristic radiologic features. The cause of choledochocele remains uncertain and it was suggested that thete are two distinct types in the pathogenesis of it, i.e., congenital and acquired. Recently, many cases of choledochocele were reported, which diagnosed by ERCP and safely treated with endoscopic unroofing and EST followed by continued observation as well as interval ERCP and/or endoscopic ultrasonography. We present here four cases of symptomaatic choledochoceles that had been managcd by end- oscopic therapy and continucd observation.
