Varicose veins may occur along the course of the common bile duct in patients with extrahepatic obstruction of the portal vein. These may cause partial biliary obstruction or excessive bleeding during biliary surgery. The cholangiographic appearance of choledochal varices is described.Key words: Biliary tract, varices -Portal hypertension, angiography. enlargement of the pancreas. ERCP demonstrated an irregular stricture in the body of the pancreas suspicious for malignancy. The pancreatic tail was not filled. The distal CBD was also visualized ( Fig. 1) and showed multiple smooth extrinsic impressions along the CBD which were felt to represent varicose venous collaterals. Celiac and superior mesenteric angiography ( Fig. 2) demonstrated complete occlusion of the splenic and distal portal veins. Extensive collateral veins were visualized in the region of the hepatoduodenal ligament along the course of the CBD. These corresponded to the impressions on the CBD seen at ERCP. The patient was subsequently proven to have carcinoma of the pancreas.Varicose veins of the esophagus, stomach, duodenum, and gallbladder have been well described [1]. Varicosities of the common bile duct are less well known. Following extrahepatic obstruction of the portal vein, hepatopetal collaterals may develop within the hepatoduodenal ligament around the common bile duct. The cholangiographic appearance of these choledochal varices has not been previously described. This case report demonstrates the appearance of common bile duct (CBD) varices visualized at endoscopic retrograde cholangiopancreatography (ERCP).
Case ReportA 58-year-old woman was referred for evaluation of weight loss, diarrhea, abdominal distention, and abdominal pain radiating to the back. Four months prior to the present admission she had undergone diagnostic laparotomy which revealed chronic pancreatitis. Multiple pancreatic biopsies at that time revealed no evidence of malignancy. The patient denied a past history of gallbladder disease, jaundice, and ethanol abuse. Physical examination demonstrated ascites. Significant laboratory determinations included alkaline phosphatase 33 U, GGTP 20 IUL, amylase 19 1UL, and total bilirubin 0.5 mg/dl (all within the normal range). The ascitic fluid amylase was normal. Ultrasound documented ascites and splenomegaly. Computed tomography of the abdomen revealed irregular Address reprint requests to :
