Currently surgical resection is still the best therapeutic method to treat hepatocellular carcinoma, but the effects of different surgical methods on postoperative recurrence of hepatocellular carcinoma are still controversial. According to the technical points and developmental course of anatomical and non-anatomical hepatectomy, this paper analyzes the published literature and draws a conclusion that success of hepatectomy depends on exact balance between residual liver reserve function and radical resection of tumor...

BACKGROUND: Severe blunt hepatic injury is a major cause of morbidity and mortality in pediatric patients. Damage control (DC) surgery has been reported to be useful in severely compromised children with hepatic injury. We applied such a technique in the treatment of a case of hemodynamically unstable grade IV blunt hepatic injury in an eight-year-old girl. This case is the first to use multimodal approaches including perihepatic packing, temporary closure of the abdominal wall with a plastic sheet, transarterial embolization (TAE), and planned delayed anatomical hepatic resection in a child...

BACKGROUND: Curative hepatectomy with bile duct resection is the treatment for perihilar cholangiocarcinoma. A locally advanced tumor necessitates hepatectomy with simultaneous vascular resection, and reconstruction remains an obstacle for surgeons. Studies have focused on the variations of hepatic arteries. Nevertheless, the anatomical alignment of the portal veins, bile ducts, and hepatic arteries are equally critical in surgical planning of curative resection for advanced tumors. We have reported promising outcomes of hepatectomy with simultaneous resection and reconstruction of the hepatic artery...

Cholangiocellular carcinoma (CCA) is the second most frequent primary liver carcinoma and is an aggressive tumor, which is mostly diagnosed in advanced stages. The overall survival is poor. Histpathological analysis of tumor biopsies or cytological analysis of biliary brushings can be used to confirm the diagnosis. A differentiation is made between distal, perihilar and intrahepatic CCA. The anatomical position determines the diagnostic and therapeutic strategy. Before diagnostic or therapeutic measures are undertaken it is essential to resolve biliary obstruction via endoscopic stenting or percutaneous biliary drainage...

Portal vein invasion (PVI) is common in hepatocellular carcinoma (HCC) and largely contributes to tumor recurrence after radical tumor resection or liver transplantation. Vasculogenic mimicry (VM) was an independent vascular system lined with tumor cells and associated with poor prognosis of HCC. The present study was conducted to evaluate the relationship between VM and portal vein invasion. A total of 44 HCC cases receiving anatomic liver resection were included in the study and were divided into groups with and without PVI...

The risk of ischemia of segment IV after split liver resection is high. This anatomical study was done to identify the arterial blood supply and the intrahepatic distribution of liver segment IV. The anatomy of segment IV was studied in 29 livers from adult cadavers. To identify the arterial blood supply of segment IV, water and ink were injected into the various branches of the hepatic artery and the outflow through segment IV and discoloration of the liver parenchyma were observed. In 23 of the 29 livers (79...

The objective of the treatment of colorectal cancer patients with unresectable liver metastases should be clearly defined at the outset. Potentially resectable patients should be distinguished from clearly unresectable patients. In defining resectability, it is important to take into account both anatomic characteristics and patient characteristic (comorbidities, symptoms, age). According to this evaluation, treatment should be tailored to each patient. The most widely accepted standard is doublet cytotoxic regimen plus biotherapy (anti-EGFR or anti- VEGF antibodies according to RAS status, but some patients could benefit from an intensified regimen, as triplet chemotherapy +/- bevacizumab, or intraarterial treatments (hepatic arterial infusion, radioembolization or chemoembolization), in order to allow resectability...

OBJECTIVES: The present research aimed to evaluate the prognostic value of a novel risk classification of microvascular invasion (MVI) in hepatocellular carcinoma (HCC) after resection. METHODS: A total of 295 consecutive HCC patients underwent hepatectomy were included in our study. We evaluated the degree of MVI according to the following three features: the number of invaded microvessels (≤5 vs >5), the number of invading carcinoma cells (≤ 50 vs >50), the distance of invasion from tumor edge (≤1 cm vs >1 cm)...

Porcine models of extended hepatectomy and liver transplantation (LT) of reduced graft have been widely used for studying the small-for-size (SFS) syndrome and the various modalities of portal inflow modulation (PIM). However, considerable heterogeneity exists among the studies and their results. The aim of this review was to assess the main advantages and drawbacks of the different porcine models of SFS LT and SFS hepatectomy, and propose a standardized anatomical nomenclature for the various models. The MEDLINE database was searched for articles reporting porcine models of reduced graft LT or hepatectomy of more than 65%...

BACKGROUND: Liver resection is effective for hepatocellular carcinoma (HCC) exceeding the Milan criteria in selected patients. However, the benefit of anatomical resection (AR) versus non-anatomical resection (NAR) has not been clarified in this patient subgroup. This study aimed to compare outcomes between AR and NAR for HCC exceeding the Milan criteria. METHODS: Data on consecutive patients with HCC exceeding the Milan criteria who underwent liver resection with curative intent over a recent 6-year interval were extracted from a prospective single-centre HCC database and examined retrospectively...

Biliary leakage is a serious complication after liver resection and represents the major cause of post-operative morbidity. In spite of already identified risk factors, little is known about the role of intra-biliary pressure following liver surgery in the development of biliary leakage. Biliary decompression may have a positive impact and reduce the incidence of biliary leakage at the parenchymal resection site. 397 patients undergoing liver resection without bilioenteric anastomosis were included in the retrospective analysis of the risk factors for the development of biliary leakage focusing on the intra-operative reduction of the biliary pressure by T-tube and liver histology...

BACKGROUND: Knowledge about anatomic variations in intrahepatic biliary ducts (IHBD) is relevant for performing biliary drainage and for avoiding bile duct injury during cholecystectomy and liver resections. Low insertion of cystic duct (LICD) is a common anatomic variant. Pancreas divisum is the commonest congenital anomaly of pancreas; it has been causally linked with recurrent acute pancreatitis (RAP). METHODS: Magnetic resonance cholangiopancreaticography (MRCP) images of 500 consecutive patients were reviewed for anatomic variants of IHBD, cystic duct, and pancreatic duct...

INTRODUCTION: Posterior right diaphragmatic hernia is rare in newborn patients but when present, is accompanied by high mortality. Pulmonary hypoplasia seems to be the main cause of death but the presence of liver involvement remains one of the reasons for poor prognosis even when intrauterine surgery is performed. CASE DESCRIPTION: In this article, we will present a rare case that was diagnosed by chance in a 65-year old adult presenting with an adenocarcinoma of the rectosigmoid junction and a right Bochdalek hernia with liver herniation and modification of the hepatic vein outflow with a natural right to left shunt...
