Los botones se encuentran debajo. The right hepatic duct RHD and left hepatic duct LHD emerge from the porta hepatis and in most instances join together after about 0. The latter continues downward in the hepatoduodenal fold of the peritoneum, passes behind the first part of the duodenum and the pancreas, then curves or bends to the right to enter in an oblique way the second part of the duodenum on biliarew posteromedical side [1] see Figures, and Adapted from Frierson [1].

The diagnosis and management of choledocholithiasis in the era of laparoscopic cholecystectomy may ampo,la facilitated by determination of a patient’s likelihood of harboring stones. This group of patients may benefit from endoscopic retrograde cholangiopancreatography ERCP.

Patients with an intermediate likelihood are those with bilirubin levels of 1. This intermediate group may benefit from intraoperative cholangiography IOCbut decisions about endoscopic stone removal versus laparoscopic or open surgical stone removal are guided by available local expertise.

In patients whose liver test results are normal and there is no ductal dilatation, jaundice, or pancreatitis, neither ERCP nor IOC is recommended based on the low probability that common bile duct stones are present. A, The sphincterotome is within the common bile duct. After completion of sphincterotomy, the basket catheter is deployed under fluoroscopic gesicula C and withdrawn through the papilla along with several common bile duct stones D.

Stone disease remains the most common cause of cholangitis in most large series in the United States.

At endoscopy, the obstructing stone is often seen bulging from the papillary orifice, as in this figure. A recent randomized, dw trial supports early endoscopic examination and intervention in cases of suspected stone-related acute cholangitis [23].

Cholangiography is the gold standard for the diagnosis of choledocholithiasis. The choledocholiths are visualized as filling defects as a column of contrast fills the common bile duct. Most stones that originate within the common bile duct are brown pigment stones.

Hilar Cholangiocarcinoma (Klatskin tumor)

Electron microscopy has revealed that such stones are often associated with bacteria [24]. Periampullary diverticula also seem to increase the risk of choledocholith billares, perhaps by serving as a reservoir for intestinal bacteria [25].

The formation of a common bile duct stone around a surgical clip is shown in panel C. Foreign bodies, including suture material placed 30 years before the patient presented with common bile duct stones, have often been reported in association with choledocholithiasis [26].

The proximal biliary tree is significantly dilated 27 mm. B, Delivery of one stone through the papilla is vatsr. The basket and stone are then gently pulled through the papillotomy.

B, An extracted stone is biliraes within the duodenal lumen. A, The bile duct is cannulated using a sphincterotome.

Colon, Gallbladder, and Appendicitis

The balloon catheter is inserted under fluoroscopic guidance, then inflated and withdrawn towards the endoscope. C, When the catheter is withdrawn, stone debris is seen emanating from the papilla. D, After sphincterotomy and stone extraction, the biliary orifice is patent. An alternative to sphincterotomy and immediate stone extraction is placement of a stent at the time of endoscopic retrograde cholangiopancreatography. This allows free passage of bile around the choledocholith and decompression of the infected biliary tree.

A, A stent bypassing a stone is seen on a cholangiogram. B, Active drainage of pus from the biliary tree after stent placement is shown.

In 18 patients seen at Duke University Medical Center with stones that could not be removed after initial sphincterotomy, stent placement resulted in a significant decrease in the size of the retained stones. All patients in this series eventually had complete duct clearance by mechanical lithotripsy, laser lithotripsy, additional stenting, stricture dilation, or extension of sphincterotomy [41]. In addition to straight stents, pitail stents can be used to decompress the biliary tree in the setting of choledocholithiasis.

After the patient responds appropriately, endoscopic retrograde cholangiopancreatography ERCP is indicated.

If the patient cannot be stabilized within 24 hours or presents with shock or mental status changeemergency ERCP should be undertaken. Options at ERCP include placement of a nasobiliary tube or endoprosthesis to establish bile duct drainage.

This elderly patient presented with acute suppurative cholangitis. ERCP revealed a faceted stone that was not easily removable. A nasobiliary tube was placed and copious pus was drained until the patient was stabilized. The patient then underwent successful sphincterotomy with stone extraction.
