Clinical data such as history, physical examination, and laboratory tests are useful in identifying patients with biliary obstruction and biliary sources of infection. However, if intervention is planned, noninvasive imaging is needed to confirm the presence, location, and extent of the disease process. Currently, the most commonly available and used noninvasive modalities are ultrasound (US), computed tomography (CT), magnetic resonance (MR), and nuclear medicine hepatobiliary scintigraphy (HIDA). US is quick, portable, readily available, and is commonly the first imaging modality used when biliary pathology is suspected...

Mycobacterium tuberculosis (TB) infection affects nearly 10 million people a year and causes 1.5 million deaths. TB is common in the immunosuppressed population with 12 % of all new diagnoses occurring in human immune deficiency virus (HIV)-positive patients. Extra-pulmonary TB occurs in 12 % of patients with active TB infection of which 3.5 % is hepatobiliary and 6-38 % is intra-abdominal. Hepatobiliary and intra-abdominal TB can present with a myriad of non-specific symptoms, and therefore, diagnosis requires a high level of suspicion...

BACKGROUND: The performance of laparoscopic cholecystectomy could be a technical challenge. Procedure success depends on multiple factors namely: hepatobiliary anatomical variations, pathologic changes in the gallbladder and surrounding tissues, pre-operative interventional attempts, the individual surgeon's skill and finally patient co-morbidities. Anticipating the attendant challenges, can help to avoid several known complications associated with this procedure. Searching a more reliable anatomical topography to adopt during laparoscopic cholecystectomy is the basis for a safe surgical technique...

Knowledge of the anatomy of the hepatic artery and its variations is important to hepatobiliary and liver transplant surgeons and interventional radiologists. We report a rare anatomic variation of liver hepatic arterial supply: a right accessory hepatic artery arising directly from the celiac trunk and observed at the time of multiorgan procurement. The anatomic variation described in this case occurs in up to 2% of cases and their knowledge is essential to avoid injuries during multiorgan procurement that could require multiple anastomoses or lead to inadvertent vessel injury...

Extracellular vesicles (EVs) are nanometer-sized, membrane-bound vesicles released by cells into the extracellular milieu. EVs are now recognized to play a critical role in cell-to-cell communication. EVs contain important cargo in the form of proteins, lipids, and nucleic acids and serve as vectors for delivering this cargo from donor to acceptor or target cell. EVs are released under both physiologic and pathologic conditions, including liver diseases, and exert a wide range of effects on target cells. This review provides an overview on EV biogenesis, secretion, cargo, and target cell interactions in the context of select liver diseases...

Colorectal cancer (CRC) is one of the leading causes of cancer-related death. Surgery, radiotherapy and chemotherapy have been till now the main therapeutic strategies for disease control and improvement of the overall survival. Twenty-five per cent (25%) of CRC patients have clinically detectable liver metastases at the initial diagnosis and approximately 50% develop liver metastases during their disease course. Twenty-thirty per cent (20%-30%) are CRC patients with metastases confined to the liver. Some years ago various studies showed a curative potential for liver metastases resection...

Bile duct injuries are the most serious complications after hepatobiliary surgery and are associated with high morbidity and mortality. The incidence of iatrogenic injuries of bile ducts has increased after the advent of laparoscopic cholecystectomy. Bile duct injuries present with biliary leak or biliary obstruction or a combination of both. Successful treatment of these complications requires a multidisciplinary team that includes biliary endoscopists, interventional radiologists and hepatobiliary surgeons...

Cholestatic itch is a feature of numerous hepatobiliary disorders such as primary biliary cirrhosis, primary sclerosing cholangitis, the inherited form of cholestasis, and intrahepatic cholestasis of pregnancy. Although undervalued by physicians, cholestatic itch can be a source of great discomfort to the patient and significantly affects quality of life. Many pruritogens such as bile salts, opioids, serotonin, and histamine have been implicated in the pathogenesis of cholestatic itch, but no causative link has ever been established...

Classically, hepatic artery pseudoaneurysms (HAPs) arise secondary to trauma or iatrogenic causes. With an increasing prevalence of laparoscopic procedures of the hepatobiliary system the risk of inadvertent injury to arterial vessels is increased. Pseudoaneurysm formation post injury can lead to serious consequences of rupture and subsequent hemorrhage, therefore intervention in all identified visceral pseudoaneurysms has been advocated. A variety of interventional methods have been proposed, with surgical management becoming the last step intervention when minimally invasive therapies have failed...

During the last decades, liver surgery had an extraordinary evolution and diffusion thanks to a drastic reduction of operative mortality and morbidity rates. A debate is ongoing about the need for centralization of liver resections in tertiary referral centers. Robust evidences showed that complex surgical procedures have lower mortality rates when performed in high-volume centers. The present expert group reviewed the literature data and proposed guidelines to identify surgical units that should be entitled to perform liver surgery in Italy...

Bile duct lesions, including leaks and strictures, are immanent complications of open or laparoscopic cholecystectomy (LC). Endoscopic procedures have gained increasing potential as the treatment of choice in the management of postoperative bile duct injuries. Bile duct injury (BDI) is a severe and potentially life-threatening complication of LC. Several series have described a 0.5% to 0.6% incidence of BDI during LC. Early recognition and an adequate multidisciplinary approach are the cornerstones for the optimal final outcome...

Preoperative portal vein embolization (PVE) is used to extend the indications for major hepatic resection, and it has become the standard of care for selected patients with hepatic malignancies treated at major hepatobiliary centers. To date, various techniques with different embolic materials have been used with similar results in the degree of liver hypertrophy. Regardless of the specific strategy used, both surgeons and interventional radiologists must be familiar with each other's techniques to be able to create the optimal plan for each individual patient...
