Rare Anatomic Variant

Anatomic anomalies of the exrrahepatic biliary tree are common and often incidental findings at endoscopic retrograde cholangiopancreatography; however, they rarely complicate therapeutic procedures such as stone extraction. The cases of two patients with biliary obstruction due to stones are presented, who were found to have the cystic duct a rising almost directly from the ampulla. This rare anatomic variant posed problems both in terms of interpretation of the cholangiogram and removal of stones. Therapeutic endoscopists should be aware of this and other anomalies of the biliary tract and of the potential problems faced in both interpretation of the cholangiogram and in therapeutic procedures.

Biliary Dilatation

Obstruction is one of the most common problems in biliary tree pathology, combined magnetic resonance imaging (MRI) and Magnetic Resonance Cholangiopancreatography (MRCP) regarded as accurate imaging modalities in diagnosis the cause of obstruction and treatment planning due to information obtain from MRCP about biliary and pancreatic ducts, information obtains from MRI cross sections about surrounding parenchyma. This study was aimed to investigate the efficacy of combined MRCP and MRI in differentiation between benign and malignant causes of biliary dilatation and their sensitivity in detection specific cause of biliary dilatation. This study involved 72 patients and conducted in Al-Diwaniyah Teaching Hospital, Iraq during a period from February 2013 to June 2017, the diagnosis of biliary dilatation was done by abdominal ultrasound to all patients followed by MRCP/MRI, the results of MRCP/MRI was compared with final diagnoses done by endoscopic retrograde cholangiopancreatography (ERCP), surgical, histopathological and laboratory results. The results revealed that a strong correlation between MRCP/MRI and other gold standard tools in differentiation between benign and malignant causes of obstruction. Sensitivity, specificity, and accuracy of MRCP in differentiation between malignant and benign causes of biliary dilatation were 98.4%, 100% & 99.7% respectively. There was a strong correlation (0.990) between MRCP/MRI & final diagnosis to determine the specific cause of obstruction, correct diagnosis the cause of obstruction in 68 patients out of 72 with a sensitivity of 94%. This study concluded that combined MRCP/MRI plays an important role in differentiation benign & malignant causes of biliary obstruction and in differentiation the specific cause of obstruction.

Cyst Rupture

A man with hydatid disease complicated by intraabdominal cyst rupture 15 years earlier, presented with cholestatic jaundice. There was intrabiliary rupture of a hydatid liver cyst on endoscopic retrograde cholangiography. Sphincterotomy was performed allow clearance of hydatid material obstructing the bile ducts and insertion of a nasobiliary catheter for irrigation and drainage. Definitive surgery was performed. While endoscopic management is gaining recognition for relieving biliary obstruction in hydatid cystobiliary rupture, surgery is still required for patients who continue to pass hydatid debris obstructing the biliary tree and increasing the risk of cholangitis.

Here, we present a case of malignant biliary tract obstruction with severe obesity, which was successfully treated by endoscopic ultrasonography-guided biliary drainage (EUS-BD). A female patient in her sixties who had been undergoing chemotherapy for unresectable pancreatic head cancer was admitted to our institution for obstructive jaundice. She had diabetes mellitus, and her body mass index was 35.1 kg/m2. Initially, endoscopic retrograde cholangiopancreatography (ERCP) was performed, but bile duct cannulation was unsuccessful. Percutaneous transhepatic biliary drainage (PTBD) from the left hepatic biliary tree also failed. Although a second PTBD attempt from the right hepatic lobe was accomplished, biliary tract bleeding followed, and the catheter was dislodged. Consequently, EUS-BD (choledochoduodenostomy), followed by direct metallic stent placement, was performed as a third drainage method. Her postprocedural course was uneventful. Following discharge, she spent the rest of her life at home without recurrent jaundice or readmission. In cases of severe obesity, we consider EUS-BD, rather than PTBD, as the second drainage method of choice for distal malignant biliary obstruction when ERCP fails.

Ultrasonographic Appearance

Case series summary This case series describes the postoperative ultrasonographic findings in six cats that underwent a cholecystoduodenostomy as treatment for extrahepatic biliary obstruction. The surgery site was identified in all six cats, most often within the right cranial abdomen as a thick-walled gall bladder, with a broad-based connection to the descending duodenum. Postoperatively, the biliary tree often remained distended, similar to its preoperative appearance. Recurrent extrahepatic biliary obstruction was suspected in three cats with worsening hyperbilirubinemia. Common bile duct distension was progressive in one of these cats and unchanged in another, but improved in the third. Intrahepatic bile duct distension resolved in one cat following surgery but reappeared with suspected recurrent biliary obstruction. In two cats, progressive echogenic biliary contents were associated with locally aggressive cholangiocarcinoma. Our findings suggest that in cats with cholecystoduodenostomy and progressive increases in hyperbilirubinemia following surgery, progressive or recurrent biliary distension and/or progressive echogenic biliary contents should prompt further investigation. Relevance and novel information Biliary diversion surgery in cats is associated with high morbidity and mortality. The ultrasonographic appearance of a postoperative cholecystoduodenostomy site has not been described, making differentiation of the expected appearance from postoperative abnormalities difficult. The goal of this study was to determine the expected ultrasonographic appearance, in order to assist in managing cats with recurrent, persistent or worsening clinical signs and biochemical abnormalities following surgery.

Ductular Cell

To shed light on ductular fluid secretion, hepatic histology and ultrastructure, cell proliferation and phenotypes, and several aspects of biliary physiology were studied in rats with ductular cell hyperplasia induced by either biliary obstruction (0-14 days) or 1-naphthylisothiocyanate (ANIT) feeding (0-28 days). In both groups of experimental animals, bile duct hyperplasia and spontaneous bile flow and secretin-induced choleresis increased with time of treatment in a linear fashion. Measurements of [14C]mannitol biliary entry and of biliary tree volume showed that the increase in both spontaneous and secretin-stimulated bile flow originated at the proliferated biliary structures. Ultrastructural examination, [3H]thymidine incorporation, and histochemical and immunohistochemical staining for various markers demonstrated that in both hyperplastic reactions the proliferated cells were the progeny of preexisting biliary epithelial cells and retained their characteristics. These results indicate that the increased bile secretory activity associated with either biliary obstruction or ANIT intoxication reflects a quantitative change due to the proliferation of biliary epithelial cells. Thus both models of bile ductular cell hyperplasia lend themselves to assessment of the transport function of intrahepatic biliary epithelium and its contribution to normal bile formation. In the present studies, we have estimated that net ductular secretion in the normal rat accounts for 10-13% of spontaneously secreted hepatic bile.
