Bile duct embryology

Ayşegül Gürsoy Çoruh, Başak Gülpınar, Hakan Baş, Ayşe Erden
PURPOSE: We aimed to evaluate the frequency of bile duct branching pattern variations at the hepatic confluence in patients with pancreas divisum (PD). METHODS: A search was performed through the hospital database using the keyword "pancreas divisum" to identify patients. The magnetic resonance cholangiopancreatography (MRCP) images of 137 patients who were diagnosed with PD between August 2011 and November 2016 were retrospectively analyzed for the presence of bile duct variations...

Liver and pancreas are closely associated organs which share a common embryological origin. They display amphicrine properties and have similar exocrine organization with parenchymal cells, namely hepatocytes and acinar cells, secreting bile and pancreatic juice into the duodenum via a converging network of bile ducts and pancreatic ducts. Here we compare and highlight the similarities of molecular mechanisms leading to liver and pancreatic cancer development. We suggest that unraveling tumor development in an organ may provide insight into our understanding of carcinogenesis in the other organ...

A double common bile duct is extremely rare among the anatomical variations in the biliary tract system. We report an incidentally encountered case of the double common bile duct and discuss the novel anatomical findings of the accessory common bile duct from the viewpoint of embryology. A unique point of our case is that the accessory common bile duct bifurcated at the level of the intrapancreatic bile duct. There is no similar case in the previous literature among type II double common bile duct in the viewpoint of anatomical findings of the accessory common bile duct...

We present a resected case of annular pancreas in which Wirsung's duct encircled the duodenum and continued directly to the main pancreatic duct in the body and tail. Furthermore, Wirsung's duct coursed along the right side of the lower bile duct near the major duodenal papilla. Histologically, the islets of Langerhans in the annular pancreas were irregular in shape and were characterized by a striking abundance of pancreatic polypeptide (PP)-positive cells. The PP-rich area that encircled the duodenum was fused with the PP-poor area in the head of the pancreas...

The ventral pancreas originally forms as an evagination of the common bile duct at 32 days gestation and its duct, the uncinate duct, eventually rotates with the ventral anlage to join the dorsal pancreas and fuse with the main pancreatic duct. Thus, though often considered a "branch" duct of the pancreas, embryologically, the uncinate duct is the "main" pancreatic duct of the ventral pancreas. This concept is not fully addressed in the current definitions of intraductal papillary mucinous neoplasms of the pancreas (IPMN) where international consensus guidelines consider the main-duct IPMN as high risk for malignancy and most small branch-duct IPMN as low risk for malignancy...

We report a patient with previous biliary symptoms and endoscopic interventions who presented with clinical features suggestive of choledocholithiasis. Open surgical exploration disclosed three gallbladders with copious stones and varying degrees of acute and chronic inflammation. Literature review revealed only 16 previously reported cases. We review the aetiology of triple gallbladder as being due to failure of rudimentary bile ducts to regress during embryological development, as well as the classification scheme of triple gallbladder based on size, location and number...

BACKGROUND/AIMS: Pancreas-preserving resection of the bile duct has been attempted as an organ preserving procedures for the treatment of low-grade malignant neoplasms of the bile duct. The fact that the lower bile duct penetrates pancreas head to join the duodenum, makes those attempts one of the challenging procedures in biliary tract surgery. Here we present a novel and unique surgical technique for anatomically resecting lower bile duct, focusing on the anatomy of the pancreas head...

The set definition of distal cholangiocarcinomas and adenocarcinomas of the pancreatic head is challenged by their close anatomical relation, similar growth pattern, and corresponding therapeutic outcome. They show a mutual development during embryologic organ formation and share phenotypic characteristics. This review will highlight the similarities with regard to the common origin of their primary organs, histopathological similarities, and modern clinical management. Thus, we propose to subsume those entities under a common superfamily...

A 52-year-old man was admitted to our hospital complaining of abdominal pain. A blood test showed high serum levels of biliary enzymes and amylase. Surprisingly, a computed tomography scan revealed complete separation of the ventral and dorsal pancreas and swelling of the ventral pancreas with choledocholithiasis. Surgical cholecystectomy was performed to remove the bile duct stones after endoscopic removal was unsuccessful. The complete separation of the pancreatic parenchyma caused by ventral pancreas malrotation seen in this case is extremely rare, and may provide important information regarding embryologic development, deformity, and malfunction of the pancreas...

Anomalous pancreatic ductal system has always enthralled the anatomists, surgeons, gastroenterologists and radiologists alike. With the growing use of MRCP, ERCP and endoscopic and surgical procedures, the knowledge of anatomical aberrations of pancreaticobiliary tract becomes extremely important. Moreover, the anomalous pancreatic duct morphology may be responsible for atypical gastrointestinal complains. We report an exceptionally rare case of two accessory ventral pancreatic ducts opening separately into the common bile duct proximal to the hepato pancreatic ampulla...

Congenital duplication of the common bile duct is an extremely rare anomaly of the biliary tract, which putatively represents failure of regression of the embryological double biliary system. Depending on the morphology of the duplicated bile duct, the anomaly can be classified into five distinct subtypes as per the modified classification (proposed by Choi et al). Among the five subtypes of bile duct duplication, type V duplication is considered to be the least common with only two previous cases of type Va variant reported in medical literature prior to the current report...

Double gallbladder is a rare embryological anomaly of clinical significance. Despite availability of modern imaging, only 50% of recently reported cases had preoperative diagnosis, which is desirable in every case to avoid serious operative complications. Double pathology in double gallbladder is extremely rare with only 3 reporting's available till date to the best of author's knowledge. With a preoperative diagnosis of double gallbladder, laparoscopic cholecystectomy can be safely and successfully performed with meticulous dissection, aided by operative cholangiogram...

Variations in the bile duct and pancreatic duct opening are related to the process of rotation and recanalization during embryologic development. Complete non-union of distal common bile duct and pancreatic duct gives rise to double papillae of Vater. The separation of the drainage of the main pancreatic duct and bile duct can be appreciated by careful assessment at the time of endoscopic retrograde cholangiopancreatograpy. The cranial orifice is a bile duct opening, whereas the caudal orifice is a pancreatic duct opening...

Hepatobiliary fibropolycystic diseases are a unique group of entities involving the liver and biliary tract, which are caused by abnormal embryologic development of the ductal plates at various stages. We experienced strange hepatobiliary fibropolycystic diseases with a complex mass composed of malformed ducts and biliary cysts, which did not belong to, and were different from, previously known malformations. They were unique in imaging and histologic features. We herein report three cases of monosegmental hepatobiliary fibropolycystic disease mimicking a mass...

Routine experiences suggest that cholangiocarcinomas (CCAs) show different clinicopathological behaviors along the biliary tree, and hilar CCA apparently resembles pancreatic duct adenocarcinoma (PDAC). Herein, the backgrounds for these similarities were reviewed. While all cases of PDAC, hilar CCA, intrahepatic CCA (ICCA) and CCA components of combined hepatocellular-cholangiocarcinoma (cHC-CCA) were adenocarcinomas, micropapillary patterns and columnar carcinoma cells were common in PDAC and hilar CCA, and trabecular components and cuboidal carcinoma cells were common in ICCA and CCA components of cHC-CCA...

BACKGROUND: Periampullary adenocarcinomas comprise pancreatic, distal bile duct, ampullary and duodenal adenocarcinoma. The epithelia of these anatomical structures share a common embryologic origin from the foregut. With steadily increasing numbers of pancreatoduodenectomies over the last decades, pathologists, surgeons and oncologists are more often confronted with the diagnosis of "other than pancreatic" periampullary cancers. The intestinal subtype of ampullary cancer has been shown to correlate with better prognosis...

OBJECTIVE: We examined the anatomy of the pancreatic duct system in patients with autoimmune pancreatitis (AIP) from the standpoint of embryological pancreatic primordial. MATERIAL AND METHODS: The pancreatic duct system involved in 83 AIP patients was embryologically divided into both ventral and dorsal pancreatic ducts (VD type), only the dorsal pancreatic duct (D type), or only the ventral pancreatic duct (V type). RESULTS: The 83 AIP patients were divided into 62 VD type, 20 D type, and 1 V type...

Embryologically, intrahepatic small bile ducts arise from hepatic progenitor cells via ductal plates, whereas the pancreato-extrahepatic biliary progenitor cells expressing the transcription factors PDX1 and HES1 are reportedly involved in the development of the extrahepatic biliary tract and ventral pancreas. The expression of cellular markers characteristic of the different anatomical levels of the biliary tree and pancreas, as well as PDX1 and HES1, was examined in cholangiocarcinoma components of combined hepatocellular cholangiocarcinoma (12 cases), intrahepatic cholangiocarcinoma (21 cases), hilar cholangiocarcinoma (25 cases), and pancreatic ductal adenocarcinoma (18 cases)...

BACKGROUND & AIMS: Biliary tree, liver, and pancreas share a common embryological origin. We previously demonstrated the presence of stem/progenitor cells of endodermal origin in the adult human extrahepatic biliary tree. This study evaluated the human foetal biliary trees as sources of stem/progenitor cells of multiple endodermal-derived mature fates. METHODS: Human foetal intrahepatic and extrahepatic biliary tree tissues and isolated cells were tested for cytoplasmic and surface markers of stem cells and committed progenitors, as well as endodermal transcription factors requisite for a liver versus pancreatic fate...

Objective. To describe the intrahepatic bile duct transposition (anatomical variation occurring in intrahepatic ducts) and to determine the frequency of this variation. Material and Methods. The researches were performed randomly on 100 livers of adults, both sexes. Main research methods were anatomical macrodissection. As a criterion for determination of variations in some parts of bile tree, we used the classification of Segmentatio hepatis according to Couinaud (1957) according to Terminologia Anatomica, Thieme Stuugart: Federative Committee on Anatomical Terminology, 1988...
