In the absence of gallbladder disease, the gallbladder is visualized within 1 hour of the injection of the radioactive tracer. [citation needed]If the gallbladder is not visualized within 4 hours after the injection, this indicates either cholecystitis or cystic duct obstruction, such as by cholelithiasis (gallstone formation).
Type VI: An isolated cyst of the cystic duct is an extremely rare lesion. Only single case reports are documented in the literature. The most accepted classification system of biliary cysts, the Todani classification, does not include this lesion. Cholecystectomy with cystic duct ligation near the common bile duct is curative. [5]
Impacted gallstone in the cystic duct is obstructing the common hepatic duct. Mirizzi's syndrome is a rare complication in which a gallstone becomes impacted in the cystic duct or neck of the gallbladder causing compression of the common hepatic duct, resulting in obstruction and jaundice.
Without appropriate treatment, recurrent episodes of cholecystitis are common. [1] Complications of acute cholecystitis include gallstone pancreatitis, common bile duct stones, or inflammation of the common bile duct. [1] [8] More than 90% of the time acute cholecystitis is caused from blockage of the cystic duct by a gallstone. [1]
This procedure may be used if the stone is very large or if the duct anatomy is complex. [5] Typically, the gallbladder is then removed, an operation called cholecystectomy, to prevent a future occurrence of common bile duct obstruction or other complications. [6]
The cystic duct may unite with the common hepatic duct so that the common hepatic duct is either very short or very long (and the bile duct in turn very long or very short, respectively), [4] or it may instead unite with the a hepatic duct. [3] Occasionally, the cystic duct may first run alongside the common hepatic duct for some distance [2 ...
The following represent indications for ERCP, particularly if or when less invasive options are not adequate or definitive: Fluoroscopic image of common bile duct stone seen at the time of ERCP. The stone is impacted in the distal common bile duct. A nasobiliary tube has been inserted.
Cholestasis is a condition where the flow of bile from the liver to the duodenum is impaired. [1] The two basic distinctions are: [1] obstructive type of cholestasis, where there is a mechanical blockage in the duct system that can occur from a gallstone or malignancy, and
