Endoscopic balloon sphincter dilation (sphincteroplasty) versus sphincterotomy for common bile duct
We wanted to emphasize that application of different radiological diagnostic procedures could be very useful in establishing the proper diagnosis, as well as ruling out the existence of abscess collections and intraluminal collections in the dilated common bile duct
. The abdominal CT revealed the presence of duodenal diverticulum, which was later-on confirmed by esophagogastroduodenoscopy.
A prospective, randomized, controlled trial of metal stents for malignant obstruction of the common bile duct
The common bile duct
(CBD) and intrahepatic duct were not dilated.

Subsequent successful deployment of a 6 mm x 60 mm bare metal stent in the cystic duct, and an 8 mm x 100 mm bare metal stent in the common bile duct
and duodenum, with antegrade contrast clearance (b).
Approximately 10% of patients who undergo laparoscopic cholecystectomy harbor common bile duct
stones [1, 2].
The viscera were exposed, the duodenum was exteriorized, and the common bile duct
was identified and dissected.
Abdominal ultrasound showed no evidence of intrahepatic or extrahepatic biliary ductal dilatation but did note a linear filling defect within the common bile duct
(CBD) as seen in Figure 1.
The cystic dilatation of the common bile duct
is a rare congenital malformation of the bile ducts .
From the right gastroepiploic artery branched the superior anterior pancreaticoduodenal artery and a short branch to the common bile duct
(Figures 3, 4, and 5).
Biliary surgery: gallbladder, common bile duct
exploration, and liver biopsy.
According to Todani et al., biliary cysts are classified into the following types: Ia--dilatation of the extrahepatic bile duct (entire); Ib--dilatation of the extrahepatic bile duct (focal segment); Ic--dilatation of the common bile duct
portion of extrahepatic bile duct; II--bile duct diverticulum (rarest, with a prevalence of 0.8%-5% (1)); III--choledochocele, i.e.
Previously, we distinguished five types of biliary cysts.1 Type I cysts are most common (50 to 85% of cases) and are characterized by cystic or fusiform dilation of the common bile duct
. These can be further subcategorized in Type IA, type IB and type IC.
