What is Choledocho duodenal mechanism?
mechanism of the choledochoduodenal junction, an effect related to the level of alcohol in the blood. The obstructive effect of alcohol would normally occur at times of pancreatic stimulation by food and alcohol and may be a major factor in alcohol- induced pancreatic disease.
How does choledochal cyst cause jaundice?
In infants, choledochal cysts usually lead to obstruction of the bile ducts and retention of bile. This leads to jaundice and an enlarged liver.
What is the pathophysiology of cholangitis?
The onset of acute cholangitis involves two factors: (i) increased bacteria in the bile duct, and (ii) elevated intraductal pressure in the bile duct that allows translocation of bacteria or endotoxins into the vascular system (cholangio-venous reflux).
Why does ascending cholangitis cause jaundice?
Ascending cholangitis, also known as acute cholangitis or simply cholangitis, is inflammation of the bile duct (cholangitis), usually caused by bacteria ascending from its junction with the duodenum (first part of the small intestine)….

What is Choledochoduodenal fistula?
Choledochoduodenal fistula (CDF) is defined as an abnormal passage between the common bile duct (CBD) and duodenum. It mostly affects patients of older age, and is an unusual clinical entity in children.
What is the mechanism of pathogenesis of pancreatitis in patients with Choledocal cyst?
The pathogenesis is probably multifactorial. In many patients with choledochal cysts, an anomalous junction between the common bile duct and the pancreatic duct can be demonstrated. This occurs when the pancreatic duct empties into the common bile duct more than 1 cm proximal to the ampulla.
How does choledochal cyst cause pancreatitis?
The vast majority of patients with choledochal cysts have APBJ [1], [2], [9]. When there is abnormal junction between the pancreatic and biliary ducts, the pancreatic secretions and enzymes reflux into CBD, and result in inflammation and weakening of CBD, which is subsequently dilated [9].
What is the difference between cholangitis and cholecystitis?
Cholecystitis is an inflammation of the gallbladder wall, usually caused by obstruction of the bile ducts by gallstones, and cholangitis is inflammation of the bile ducts (Thomas, 2019).
What is cholangitis cause?
In most cases cholangitis is caused by a blocked duct somewhere in your bile duct system. The blockage is most commonly caused by gallstones or sludge impacting the bile ducts. Autoimmune disease such as primary sclerosing cholangitis may affect the system.
How is cholecystitis different from cholangitis?
How can you tell the difference between acute cholecystitis and cholangitis?
The clinical features of cholangitis are very similar to other biliary pathologies. A biliary colic will present with a colicky RUQ pain yet without fever, leucocytosis, or jaundice. Cholecystitis will present with RUQ pain and fever yet jaundice will be absent.
What is emphysematous cholecystitis?
Acute emphysematous cholecystitis is an uncommon condition caused by gas-forming organisms and characterized by the presence of gas in the wall and lumen of the gallbladder. Its incidence is higher among male diabetics.
Can a choledochododuodenostomy be performed on the pancreas?
The approach to the pancreatic duct is the same as for standard ERCP. Choledochoduodenostomy is a simple form of surgery that provides midextrahepatic bile duct drainage for benign conditions such as distal bile duct stricture or recurrent choledocholithiasis.
What kind of surgery is needed for choledochoduodenal fistula?
Patients with choledochoduodenal fistula were confirmed by endoscopic retrograde cholangiography. Of the 61 patients needing surgical intervention, clinical outcomes were excellent in 57 patients, and five patients underwent successful laparoscopic surgery for repairing the choledochoduodenal fistula.
What causes side to side anastomosis with choledochoduodenostomy?
The side-to-side anastomosis may be complicated by recurrent fever, abdominal pain, liver abscess, pancreatitis, or cholangitis. Bile duct impaction caused by trapped debris distal to a side-to-side choledochoduodenostomy is referred to as sump syndrome (Fig. 31.25, B, C, F ).
How is the hepatic duct accessed in a choledochoduodenostomy?
In an end-to-side choledochoduodenostomy, the common hepatic and intrahepatic ducts can be accessed only through the duodenal anastomosis.
