BACKGROUND: Although laparoscopic major hepatectomy (LMH) is becoming increasingly common in specialized centers, data regarding laparoscopic extended major hepatectomies (LEMH) and their outcomes are limited. The aim of this study was to compare the perioperative characteristics and postoperative outcomes of LEMH to standard LMH. METHODS: All patients who underwent purely laparoscopic anatomical right or left hepatectomy and right or left trisectionectomy between February 1998 and January 2016 are enrolled...

BACKGROUND: The anatomic variations of the visceral arteries are not uncommon. The liver arterial blood supply shows 50% variability between humans, with the most common anatomy being one hepatic artery arising from the celiac trunk and one pancreatico-duodenal arcade between the celiac trunk and the superior mesenteric artery. Occlusion of one artery are mostly asymptomatic but may become clinically relevant when surgery of the liver, bile duct or the pancreas is required. If these pathologies are not reversible, an oncologic pancreatic head resection cannot be performed...

Background: Hepatic metastatectomy and ablation are associated with prolonged survival, but not all lesions are anatomically amenable to these therapies. We evaluated safety and initial efficacy of segmental ablative transarterial radioembolization, or radiation segmentectomy (RS), as a treatment for hepatic metastases. Methods: A single institution retrospective analysis was performed of patients with hepatic metastases, determined unamenable to resection by a multidisciplinary tumor board, treated with RS from 2015-2017...

INTRODUCTION: Medullary carcinoma accounts for 1-2% of all thyroid malignancies. 13-20% of patients present with distant metastasis, with 45% of the cases affecting the liver. CLINICAL CASE: A 50-year-old woman, diagnosed with medullary thyroid carcinoma, was treated with total thyroidectomy and a modified neck dissection in 1999. Two lymph node recurrences in the neck were treated with surgical resection; during surveillance, she developed elevated calcitonin levels, the recurrence site was identified with 18 F-DOPA PET/CT in the liver...

BACKGROUND: Preclinical breast cancer models recapitulating the clinical course of metastatic disease are crucial for drug development. Highly metastatic cell lines forming spontaneous metastasis following orthotopic implantation were previously developed and characterized regarding their biological and histological characteristics. This study aimed to non-invasively and longitudinally characterize the spatiotemporal pattern of metastasis formation and progression in the MDA-MB-231-derived triple negative LM2-4 and HER2+ LM2-4H2N cell lines, using bioluminescence imaging (BLI), contrast enhanced computed tomography (CT), fluorescence imaging, and 2-deoxy-2-[fluorine-18]fluoro-D-glucose positron emission tomography ([18F]FDG-PET)...

The prognosis of patients with colorectal liver metastases (LM) is mostly established on clinical variables or on the anatomic extent of colorectal cancer (CRC). Histopathological factors of LM which may actually reflect the biological aggressiveness of the tumor are not routinely considered to define the risk of worse clinical outcome in those patients. The number of poorly differentiated clusters (PDC) of neoplastic cells in primary CRC is associated with metastatic risk and bad prognosis, but PDC presence in LM has been barely analyzed thus far...

BACKGROUND: Although spontaneous tumour rupture is a life-threatening complication of hepatocellular carcinoma (HCC), staged hepatectomy for HCC controlled after transcatheter arterial embolization (TAE) could provide a better prognosis. Laparoscopic liver resection (LLR) has been accepted worldwide and has been expanded from minor resection to anatomical major resection. We herein report the first case of pure laparoscopic left hepatectomy for ruptured HCC controlled after TAE. CASE REPORT: A 66-year-old man was transferred to our Institute because of abdominal pain and decreased consciousness...

BACKGROUND: Liver resection is a potentially curative therapy for hepatocellular carcinoma (HCC). LLR is a newly developed and safe technique associated with shorter hospital stay, less pain, better cosmetic outcomes, and similar complication rates as open surgery; however, data on its long-term outcomes remain scarce. METHODS: We retrospectively examined the clinical and follow-up data of 234 patients who underwent LLR (performed by a single surgeon in all cases) for the primary treatment of HCC between July 2007 and December 2015 at Asan Medical Center...

Amyloidosis is defined as abnormal aggregation of amyloid proteins. Amyloidosis can be localised or systemic affecting the lung, heart, spleen, liver and kidneys. The most common form of pulmonary amyloidosis is the nodular type. The disease is idiopathic and linked to many systemic diseases. The clinical manifestations and prognosis of respiratory tract amyloidosis depends on its etiology and anatomical location. Radiologically, the nodular pulmonary amyloidosis may appear as single or multiple nodules in any lobe, and, therefore, may mimic as primary pulmonary or metastatic neoplasms...

Biliary complications are a common cause of morbidity after liver transplantation, with biliary stone formation being a known occurrence generally upstream of a stricture. A 12-year-old boy, who underwent an orthotopic liver transplantation at 11 months of age for biliary atresia, presented acutely with fever and abdominal pain. Cross-sectional imaging revealed Roux-en-Y limb dilatation and thickening. He was explored and was found to have an ischemic Roux limb secondary to an obstructing enterolith. A segmental bowel resection and revision of his hepaticojejunostomy was performed...

Ischemic complications after pancreatic surgery can raise postoperative mortality from 4 to 83 per cent. Variants in vascular anatomy play a major role in determining such complications, but they have been only occasionally reported in the literature. We retrospectively analyzed 100 records of patients consecutively treated between January 2011 and December 2013 for resectable malignant diseases who underwent pancreaticoduodenectomy (PD) or total pancreatectomy to state the statistical impact of anatomical vascular variations in surgical outcomes (mean surgical timing, mean blood loss during surgery, and postoperative major complications onset) and to state whether preoperatively undetected vascular anomalies (VA) can raise the risk of postoperative ischemic complications...

BACKGROUND: Biliary leakage is a major contributor to morbidity after hepatectomy. A score to predict severe posthepatectomy biliary leakage (PHBL) was recently developed by the French Association of Hepatopancreatobiliary Surgery and Transplantation (ACHBT). The aim of the study was to validate and optimize the score upon an external cohort. STUDY DESIGN: The ACHBT score uses 5 factors (blood loss, remnant ischemia, anatomical resection of segment 8, transection along right aspect of left intersectional plane and associating liver partition and portal vein ligation for staged hepatectomy) to predict severe PHBL...

Background: Laparoscopic liver resection (LLR) of colorectal liver metastases (CLM) is increasingly performed in specialized centers. While there is a trend towards a parenchyma-sparing strategy in multimodal treatment for CLM, its role is yet unclear. In this study we present short- and long-term outcomes of laparoscopic parenchyma-sparing liver resection (LPSLR) at a single center. Patients and methods: LLR were performed in 951 procedures between August 1998 and March 2017 at Oslo University Hospital, Oslo, Norway...

Liver resection is the standard treatment for any liver lesion. Laparoscopic liver resection is associated with lower intra-operative blood loss and fewer complications than open resection. Access to the posterior part of the right liver lobe is very uncomfortable and difficult for surgeons due the anatomic position, especially when employing laparoscopic surgery. Based on these experiences, a new laparoscopic device was developed that is capable of bending its long axis and allowing the application of radiofrequency energy in areas that were not technically accessible...

Regarding the history of liver surgery, Latin American pioneers have only occasionally been mentioned in the Anglo-Saxon literature. One of such rare cases was Uruguayan surgeon Gerardo Caprio, who in 1931 published a report about a resection of the left lobe of the liver. This was done during an uneventful period in the development of ideas on this surgical technique, following the remarkable advances made in the last quarter of the 19th Century. The anatomic and liver manipulation concepts used by Caprio had been developed by Merola in reports dating back to 1916 and 1920, which revealed well-grounded disagreements with the most renowned anatomists of the time...

BACKGROUND: Resection of hepatocellular carcinoma located in the caudate lobe is challenging because this anatomical location is difficult to approach, especially the caval portion. METHODS: We performed resection of the caval portion of the caudate lobe using a ventral approach combined with the resection of segment IV, VII, or VIII for hepatocellular carcinoma in 41 patients (extended segmentectomy group). As a control group, 138 patients with hepatocellular carcinoma who underwent segmentectomy for IV, VII, or VIII (segmentectomy group) were studied...
