Although rare, unintended thermal injury to organs surrounding the ablation zone can lead to severe complications. Over the past 15 years, different protective methods have been developed to limit risk of complications, and expand indications to include more challenging lesions in various locations including liver, kidney, lung and bone. The most frequently used techniques include hydrodissection, carbodissection, balloon interposition and probe torqueing. In most cases, tumours can be physically separated from sensitive structures, reducing risk of thermal injury...

PURPOSE: Bile duct injuries (BDIs) are more frequent during laparoscopic cholecystectomy (LC). Several BDI classifications are reported, but none encompasses anatomy of damage and vascular injury (A), timing of detection (To), and mechanism of damage (M). Aim was to apply the ATOM classification to a series of patients referred for BDI management after LC. METHODS: From 2008 to 2016, 26 patients (16 males and 10 females, median age 63 years, range 34-82 years) with BDIs were observed...

We present the case of a 51-year-old woman with a history of uterine cancer who presented to the emergency room with a clinical picture of acute cholangitis. An abdominal ultrasound and a computed tomography scan were performed, revealing a gigantic lymphadenopathy mass compressing the common bile duct and the duodenum. After failure to perform an endoscopic retrograde cholangiopancreatography (ERCP) due to a modified anatomy, we performed an endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) and placed a Hot AXIOS 10Fr/10 mm stent with efficient biliary drainage...

A biliary enteric fistula (BEF) is a rare, abnormal communication between any segment of the biliary tree with any portion of the small or large intestine. BEF is more frequently diagnosed with the increasingly widespread use of endoscopic retrograde cholangiopancreatography. Different theories have been postulated regarding the etiology of this fistula formation, with the most likely cause being gallstones. Treatment modalities, ranging from conservative management to surgical reconstruction, show varying levels of success...

BACKGROUND: There continues to be controversy regarding the optimal screening modality in patients with symptomatic cholelithiasis and suspected common bile duct (CBD) stones. The aim of this study was to assess the diagnostic accuracy of laparoscopic ultrasonography (LUS) compared to magnetic resonance cholangiopancreatography (MRCP). METHODS: Both LUS and MRCP were performed to evaluate the CBD stones and biliary anatomy in 200 patients undergoing laparoscopic surgery...

Background: Mirizzi syndrome is a condition difficult to diagnose and treat, representing a particular "challenge" for the biliary surgeon. The disease can mimic cancer of the gallbladder, causing considerable diagnostic difficulties. Furthermore, it increases the risk of intraoperative biliary injury during cholecystectomy. The aim of this study is to point out some particular aspects of diagnosis and treatment of this condition. Methods: The clinical records of patients with Mirizzi syndrome, treated in the last five years, were reviewed...

INTRODUCTION: Left-sided gallbladder without situs viscerum inversus (LSG-woSVI) is defined as a gallbladder located under the left lobe of the liver; to the left of the round/falciform ligament, but with all other viscera maintaining normal anatomical relationships. This is a rare congenital anomaly with a reported prevalence that ranges from 0.04% to 1.1%. It is usually an incidental intraoperative finding, and can be associated with anatomic abnormalities of the biliary tree, portal system and vasculature...

Clinical applications of EUS for the liver have been recently increasing. They include the screening and diagnosis of liver parenchymal disease and malignant tumors as well as EUS-guided interventions such as hepaticogastrostomy, tumor ablation therapy, and portal pressure gradient measurement. Although the segmental localization of the targeted tumor, bile duct, and vessel in the liver is important to complete these procedures, little information is available regarding hepatic segmental anatomy on EUS. The liver can be visualized with EUS by transgastric and transduodenal scanning, and the EUS determination of segmental location can be achieved using various anatomical landmarks...

In hepatobiliary surgery, fluorescence imaging enables identification of subcapsular liver tumors through accumulation of indocyanine green after preoperative intravenous injection in cancerous tissues of hepatocellular carcinoma and in noncancerous hepatic parenchyma around intrahepatic cholangiocarcinoma and liver metastases. Indocyanine green-fluorescence imaging can also be used for visualizing extrahepatic bile duct anatomy and hepatic segmental boundaries, enhancing the accuracy of open and laparoscopic hepatectomy...

The efficacy of balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (ERCP) for patients with surgically altered gastrointestinal anatomy has been previously reported. However, although this method allows the endoscope to reach the papilla, successful biliary cannulation is difficult. Unlike normal ERCP, directions in these patients are reversed, and it is difficult to adjust the catheter in the direction of the bile duct. Intubating the cannula to the papilla is therefore time-consuming...

BACKGROUND AND AIMS: Although balloon enteroscopy-assisted ERCP (BE-ERCP) is effective and safe for benign biliary diseases in patients with surgically altered anatomy (SAA), BE-ERCP is not always successful. Recently, EUS-guided antegrade intervention (EUS-AI) including a 1-stage or 2-stage procedure has been developed for BE-ERCP failure cases. The aim of the present study was to evaluate the outcome of EUS-AI for benign biliary diseases with SAA. METHODS: Of 48 patients in whom BE-ERCP failed, percutaneous transhepatic intervention was performed in 11 patients...

Malignant bile duct obstruction is a common entity in clinical practice and is infrequently caused by non-biliopancreatic neoplasms. We report the case of a male admitted with malignant obstruction of the biliary tract, showing after numerous studies that this obstruction was the initial presentation of a stage IV adenocarcinoma of the lung. Pulmonary neoplasms have variable behaviors being often spread at time of diagnosis, especially in the more aggressive subtypes. However, it is uncommon its manifestation as obstructive jaundice and when this happens it is usually due to liver damage and not to metastases to periampullary region that are extremely infrequent...

Gallbladder duplication is a rare anatomic variant of biliary anatomy, which can present diagnostic and treatment challenges. In this case, a 49-year-old male presented with classic symptoms of biliary colic to his primary care physician, and while computed tomography (CT) noted the presence of gallstones, neither CT nor ultrasound was able to locate a gallbladder within the gallbladder fossa. Initial surgery found and cauterized a rudimentary gallbladder, but symptoms persisted, requiring a second surgery and secondary analysis of CT, ultrasound, and magnetic resonance imaging with magnetic resonance cholangiopancreatography...
