  Background: The great variability of the extrahepatic bile duct (EBD) has clinical-surgical implications. The objective of this study was to characterize the morphological expressions of EBD. Methods and findings This descriptive study, done by injecting a semi-synthetic (Palatal GP40L 85%; styrene 15%) impregnated with mineral green dye into the gallbladder, to determine the anatomical characteristics and the biometrics of EBD in 33 blocks formed from the supra-mesocolic floor.The gallbladder presented a length of 66.9 ± 1.7 mm. The Hartmann´s Pouch was observed in 16 specimens (50%). The lengths of the cystic duct (CD), common hepatic duct (CHD) and common bile duct (choledoch duct) were 27.8 ± 1.6 mm, 28.6 ± 11.39 mm and 60.6 ± 11.6 mm respectively. The presence of accessory hepatic ducts (AHD) was found in three samples (9.1%). In 29 specimens  (87.9%) the cystic duct  presented medium length, while in 4 cases (12.1%) the CD was long (P < 0, 05). The trajectory of the lateral oblique of CD was present in 23 cases (69.7%), with statistically significant differences in relation to the other trajectories of the CD (P <0, 05). In 18 samples (55%) the cystic-hepatic union appeared at the level of the middle third of the EBD, while in 15 (45%) cases the union of the CD was low (P<0,05). Conclusions The mathematical distribution of the segments of the EBD, carried out in this study, provides reliability to the assessment of the cystic-hepatic junction level. The presence of CHA and the level of the cysto-hepatic junction are important anatomical references, especially in emergency room procedures.

Abstract Introduction Congenital choledochal malformations (CCMs) are characterized by intra- and/or extrahepatic bile duct dilatation. Five basic types (1–5) are recognized in Todani's classification and its modifications, of which types 1 and 4 typically have an associated anomalous pancreatobiliary junction and common channel (CC). We describe two cases with previously undescribed features. Case Report 1 Antenatal detection of a cyst at porta hepatis was made in an otherwise normal girl of Iranian parentage. She was confirmed to be a CCM (20 mm diameter), postnatally, with no evidence of obstruction. Surgical exploration was performed at 12 weeks. She had an isolated cystic dilatation of the right-hepatic duct only. The left-hepatic duct and common bile duct (CBD) were normal without a CC. Histology of the resected specimen showed stratified squamous epithelium. Case Report 2 A preterm (31 weeks of gestation) boy of Nigerian parentage was presented. His mother was HIV + ve and he was treated with nucleoside reverse transcriptase inhibitors following birth. He had persistent cholestatic jaundice and a dilated (10 mm) bile duct from birth. Although the jaundice resolved, the dilatation persisted and increased, coming to surgery aged 2.5 years. This showed cystic dilatation confined to the common hepatic duct, and otherwise normal distal common bile duct and no CC. Result Both underwent resection with the Roux-en-Y hepaticojejunostomy reconstruction to the transected right-hepatic duct alone in case 1, leaving the preserved left duct and CBD in continuity, and to the transected common hepatic duct in case 2. Conclusions Neither choledochal anomaly fitted into the usual choledochal classification and case 1 appears unique in the literature.

ABSTRACTUnder the prevailing overall Conditions of all veterinarians for the diagnosis of biliary diseases, application of surgical procedures and liver transplantation in Cats as carnivorous pet animal, and Rabbits as herbivorous pet animal and also as a human model in research. The present study was constructed on twelve native breeds of rabbits (Oryctolagus cuniculus) and eighteen adult domestic cats (Felis catus domesticus). We concluded that, in brief; the rabbit gall bladder was relatively small, fixed by several small hepato-cystic ducts to its fossa. The rabbit bile duct was formed commonly by the junction of the left hepatic duct and the cystic duct. The cystic duct was commonly fairly large, received the right hepatic duct that collected the right lobe in its route to enter the duodenum, the bile duct receives the branch of the caudate process of the caudate lobe. The present study revealed other four anatomic variations dealing with the shape and size of the feline native breed’s gall bladder from fundic duplication, bilobed, truncated fundus and distended rounded fundus. Commonly, the bile duct was formed by the triple convergence of the left and the right hepatic ducts with the cystic duct. However, in some exceptional cases a short common hepatic duct was formed. Sonographically, the normal gall bladder in rabbit appeared small, elongated with anechoic lumen bordered by right lobe laterally and quadrate lobe medially and has no visible wall, but in cat varied in conformation, bordered by the right medial lobe laterally and the quadrate lobe medially surrounded by echogenic wall.

Abstract The extrahepatic bile duct morphometry was determined by the analysis of the colangiographies performed at Medimar Imaging Services SRL of the “St. Andrei “in Constanta on a General Electric Brightspeed Select CT scanner 16 slides. For the left liver duct found a caliber of 3.5-6.6 mm, its length ranging from 4.2-24.9 mm, and the right hepatic duct had a caliber ranging from 4.2-7.2 mm, the length being between 3.0-25.0 mm. At the confluence of the two hepatic ducts an angle of 35.0-124.1° was formed. In the common hepatic duct we found a caliber of 3.9-9.7 mm, in length between 20.2-52.9 mm. Cystic duct having a size of 2.4 to 5.5 mm, finding a length ranging from 24.6 to 66.4 mm. The angle formed at the end of the cystic duct in the hepatic duct had a value between 6.2-55.8°, and between the cystic and biliary ducts an angle of between 88.5-170.4° was formed. The coledoc duct had a caliber of 3.1-14.7 mm and a length of 19.8-57.3 mm.

We encountered 10 patients with bile duct injuries during laparoscopic cholecystectomy. Their causes were electrocautery in 2 patients, misjudgment in 2, mechanical injury in 3, aberrant bile duct in 2, and weakness of the bile duct wall in one. The sites of injury were cystic duct in 4 patients, common bile duct in 2, aberrant bile duct in 2, common hepatic duct in one, and common bile duct plus right hepatic duct in one. Treatments for the injuries discovered intraoperatively consisted of T-tube drainage above in 2 patients, re-ligation of the cystic duct in one, ligation of an aberrant bile duct in one, simple suture and T-tube in one, and choledochojejunostomy in one. In the remaining 4 patients discovered postoperatively, 2 were conservatively treated by endoscopic retrograde biliary drainage. The duration of hospitalization was 9–12 days in the 4 patients with simple suture or ligation, 10–21 days in 2 cases of bile drainage, and 34–43 days in 3 with T-tube drainage. The patient with choledochojejunostomy suffered repeated cholangitis, resulting in hepatic abscess with hospitalization for 6 months. Since laparoscopic surgery should be minimally invasive, meticulous attention is necessary before and during surgery to avoid bile duct injury.

Mirizzi syndrome is described in the 1940s as follows: partial obstruction of the secondary common hepatic duct by gallstones, impacted on the cystic duct or gallbladder infundibulum, associated with the inflammatory response that involved the cystic duct and the common hepatic duct. As it is a rare and delicate condition, differential diagnosis is extremely important, in which the patient's clinical condition is verified through anamnesis and complementary exams, where immediately after the surgical intervention can be performed. This work aims to describe, through a literature review, the clinical aspects and the surgical technique in Mirizzi Syndrome. Were used as a database for research sites containing scientific articles available online such as Virtual Health Library (VHL), Scientific Electronic Library Online (Scielo) and PubMed. 154 articles were found through the descriptors, where after applying the inclusion and exclusion criteria 11 articles remained to write the work. According to the articles surveyed, it is clear that most of them do not report the syndrome as the main diagnosis, possibly because it is a pathology with signs and symptoms very close to other diseases of the bile duct, therefore leaving the syndrome sometimes described in the context of these other diseases. Finally, it concludes that even though the preoperative diagnosis is rare, it should be suspected in individuals undergoing biliary surgery.

Proximal extrahepatic bile ducts are the biliary tree segment within formal boundaries from cystic ductcommon hepatic duct junction to sectoral hepatic ducts. Despite being a focus of attention of diagnostic and interventional radiologists, endoscopists, hepatobiliary surgeons and transplantologists they weren’t comprehensively described in available papers. The majority of the authors regard bile duct confluence as a group of merging primitively arranged tubes providing bile flow. The information on the proximal extrahepatic bile duct embryonal development, variant anatomy, innervation, arterial, venous and lymphatic supply is too general and not detailed. The present review brought together and systemized exiting to the date data on anatomy and function of this biliary tract portion. Unique, different from the majority of hollow organs organization of the proximal extrahepatic bile duct adapts them to the flow of the bile, i.e. viscous aggressive due to pH about 8.0 and detergents fluid, under higher wall pressure than in other parts of biliary tree.

Potential Benefits

Iatrogenic biliary injury is the most significant complication after laparoscopic cholecystectomy. We present our experience with an alternative diagnostic approach using transcatheter cholangiography (TCC) through a Jackson-Pratt (JP) drain and discuss potential benefits and limitations of the technique. From March 2002 to February 2012, 40 patients with major postoperative biliary injury underwent biliary reconstruction at our institution. Mean age was 51.7 ± 18.1 years (range, 19 to 86 years) with 30 (75%) females. Seventeen (42.5%) injuries were detected intraoperatively and in 13 (32.5%) cases, JP drains were placed for biliary drainage. Lesions were classified according to Bismuth grade: I (10 patients [25%]), II (10 patients [25%]), III (six patients [15%]), IV (10 patients [25%]), and V (four patients [10%]). TCC was performed in seven patients with JP drains (53.8%). It fully defined the injury site in three cases of limited magnetic resonance cholangiopancreatography (MRCP) such as common hepatic duct and common bile duct leaks and in four cases (57.1%) that endoscopic retrograde cholangiopancreatography (ERCP) was limited as a result of clipping of the distal common bile duct. TCC showed promising results in cases of limited MRCP and ERCP such as fistulous orifices or leakage. It may represent an alternative adjunct in the diagnostic armamentarium of complex biliary injuries.
