OBJECTIVES: Resection of a leiomyosarcoma of the inferior vena cava (IVC) requires venovenous bypass, especially if IVC clamping above the hepatic veins is planned. This report describes the application of external skin surface cooling for off-pump resection of a primary IVC leiomyosarcoma adjacent to the hepatic veins with graft IVC reconstruction in conditions of suprahepatic caval clamping and uninterrupted Pringle's manoeuvre. METHODS: A 62-year-old woman presented with IVC leiomyosarcoma adjacent to the hepatic veins...

Preoperative systemic inflammatory response is associated with a poor long-term prognosis following resection surgery for malignant tumors. Several markers of systemic inflammation have been reported to be associated with the outcome; however, they have not currently been fully investigated. Therefore, the association between preoperative peripheral blood neutrophil count and oncological outcome following hepatic resection for colorectal liver metastasis (CRLM) was retrospectively investigated. The present study comprised 89 patients who had undergone hepatic resection for CRLM between January 2000 and March 2010...

Assessment of hepatic functional reserve is important to enable the selection of appropriate treatment methods and safe hepatic resection in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). In the present study, an evaluation was made of the clinical value of combining the Child-Pugh score (CPS) with the standardized future liver remnant (sFLR) measurement to predict postoperative liver dysfunction (PLD). A total of 61 HBV-related HCC patients undergoing liver volumetry prior to hepatectomy were enrolled in the study...

BACKGROUND: Noncompressible torso hemorrhage is the leading cause of potentially survivable trauma in far-forward combat environments. Our aim was to examine the effect of small-volume 3% NaCl adenosine, lidocaine, and Mg (ALM) bolus and 0.9% NaCl/ALM "drip" on survivability and cardiac/gut/kidney function in a rat model of hepatic hemorrhage and shock. METHODS: Male Sprague-Dawley rats (428 ± 4 g) were anesthetized and randomly assigned to one of five groups (n = 16): (1) Sham, (2) No treatment, (3) Saline controls, (4) ALM therapy, and (5) Hextend...

Following the introduction of the first laparoscopic liver resection, after ∼25 years, a critical reappraisal seems to be warranted. Liver resection represents the first choice for curing early hepatocellular carcinoma (HCC) allowing a curative chance also in selected patients with intermediate stage tumors. The criteria for liver resectability by laparoscopy remains the same for open surgery, which is oncological criteria (absence of extrahepatic tumor location; completely resectable R0 resection), anatomic (resectability of involved segment with its own blood surely and biliary drainage; absence of vascular invasion of portal or hepatic veins) and technical (possibility to leave in place a residual volume ≥40%)...

BACKGROUND: Surgical indications for liver hemangioma remain unclear. METHODS: Of 510 patients undergoing surgical resection for liver hemangioma in 118 Japanese centers between 1998 and 2012, abdominal symptoms, diagnostic accuracy, and surgical outcomes were analyzed to propose size-based surgical indications. Patients were classified into four groups based on tumor size: Group A) ≤5 cm (n = 122, 24%), B) 5-10 cm (n = 164, 32%), C) 10-15 cm (n = 124, 24%), and D) >15 cm (n = 100, 20%)...

The long-term prognosis following resection of hepatocellular carcinoma (HCC) remains unsatisfactory as a result of a high incidence of recurrence. Prevention of recurrence is the most important strategy to improve the long-term survival results. The role of hepatectomy itself, as an accelerator of carcinogenesis, has not been adequately evaluated in HCC patients. Studies in animal models have revealed a link between liver regeneration under chronic inflammation and hepatic tumorigenesis. Inhibiting different signal transduction pathways during liver regeneration without compromising the ability of the liver to regenerate appears to be a rational strategy and may decrease HCC development and recurrence...

BACKGROUND: Surgical resection of all sites of disease, in combination with effective systemic chemotherapy, offers the only potential chance for cure for patients with stage IV colorectal cancer (CRC). Coordinated multistage resection using a minimally invasive approach may provide optimal oncologic outcome while potentially offering the benefit of decreased morbidity. PATIENT: A 66-year-old women presented with transverse colon cancer and synchronous metastasis (CRLM) in segment IV involving the middle hepatic vein and main left portal pedicle, as well as the left adrenal gland...

Primary hepatic leiomyosarcoma is an extremely rare tumor. The diagnosis is difficult, and its etiologic factors have not been clarified. A 63-year-old woman with numerous cysts in her kidneys and liver was diagnosed with autosomal dominant polycystic kidney disease (ADPKD). Several members of her family also had ADPKD. She underwent treatment with tolvaptan to inhibit cyst growth and slow the decline in kidney function. Eight months after the start of the therapy, she was hospitalized with fatigue and fever of unknown origin...

BACKGROUND: The feasibility and efficacy of adjuvant hepatic arterial infusion (HAI) in preventing the development of liver metastases in patients with advanced colon carcinoma have not been validated. The aim of this randomized controlled study was to compare the feasibility of HAI and the protective effect against liver metastasis after curative resection to those of systemic chemotherapy. METHODS: Between July 2000 and June 2003, 91 patients were enrolled. Patients were randomly assigned to receive 5-fluorouracil (5-FU) via continuous venous infusion (CVI) or intra-hepatic arterial weekly high-dose 5-FU (WHF)...

Anatomical variants of the celiac trunk (CT) branches and especially these of hepatic arteries (HAs) are among the most common variants of the arterial tree. The knowledge of the wide variability in hepatic arterial supply is of paramount importance in hepatobiliary, pancreatic, gastric, and esophageal surgery, as well as in liver transplantations. The purpose of this case report is to describe a rare variant discovered during abdominal dissection of a 74-year-old male cadaver of Greek origin, in which the common hepatic artery was absent and its branches, the proper hepatic artery (PHA) and the gastroduodenal artery (GDA) had an aberrant and separate origin...

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer, accounting for 10-15% of primary hepatic malignancy. The incidence and cancer-related mortality of ICC continue to increase worldwide. At present, hepatectomy is still the most effective treatment for ICC patients to achieve long-term survival, although its overall efficacy may not be as good as that for patients with hepatocellular carcinoma (HCC) due to the unique pathogenesis and clinical-pathological profiles of ICC. Viral infection, lithiasis and metabolic factors may all be associated with the pathogenesis of ICC...

BACKGROUND: Liver resection or partial hepatectomy (PH) is still the most commonly used therapeutic option for hepatocellular carcinoma (HCC) at present. However, the impaired regenerative ability induced by the accompanied liver cirrhosis is an important risk factor of posthepatectomy liver failure, and posthepatectomy liver failure is a feared complication that accounts for up to 75% of mortality after extensive liver resection. MicroRNA(miR)-203 is a tumor suppressor of HCC and may act as a positive intermediary in A20-enhanced interleukin (IL-6)/signal transducer and activator of transcription 3 (STAT3) pro-proliferative signals, which may promote liver regeneration after PH...

The Milan criteria were originally defined in the context of adult liver transplantation for patients with hepatocellular carcinoma and cirrhotic livers. The aim of the criteria was to select patients with small tumours and no disease spread who had a good chance of success, thus avoiding futile transplants. This objective was reached successfully. For the management of selected children with unresectable hepatoblastoma, an almost opposite strategy was proposed and has been implemented in the past two decades, in which transplantation is indicated on the basis of large tumour size and anatomy that precludes the possibility of safe and radical resection...

Acute kidney injury (AKI) is a major complication of hepatic surgeries. The primary cilium protrudes to the lumen of kidney tubules and plays an important role in renal functions. Disruption of primary cilia homeostasis is highly associated with human diseases including AKI. Here, we investigated whether transient hepatic ischemia induces length change and deciliation of kidney primary cilia, and if so, whether reactive oxygen species (ROS)/oxidative stress regulates those. HIR induced damages to the liver and kidney with increases in ROS/oxidative stress...

Hepatitis C virus represents one of the rising causes of hepatocellular carcinoma (HCC). Although the early diagnosis of HCC is vital for successful curative treatment, the majority of lesions are diagnosed in an irredeemable phase. This work deals with a comparative ultrastructural study of experimentally gradually induced HCC, surgically resected HCC, and potential premalignant lesions from HCV-infected patients, with the prospect to detect cellular criteria denoting premalignant transformation. Among the main detected pathological changes which are postulated to precede frank HCC: failure of normal hepatocyte regeneration with star shape clonal fragmentation, frequent elucidation of hepatic progenitor cells and Hering canals, hepatocytes of different electron density loaded with small sized rounded monotonous mitochondria, increase junctional complexes bordering bile canaliculi and in between hepatocyte membranes, abundant cellular proteinaceous material with hypertrophied or vesiculated rough endoplasmic reticulum (RER), sequestrated nucleus with proteinaceous granular material or hypertrophied RER, formation of lipolysosomes, large autophagosomes, and micro-vesicular fat deposition...

BACKGROUND: Irreversible electroporation (IRE) has emerged as a novel, safe ablative therapy for peri-vascular lesions. However, there remains a paucity of data on long-term outcomes. METHODS: We identified patients who underwent open IRE (1/2011-6/2015) for primary and secondary hepatic malignancies. Local ablation-zone recurrence (LR) was determined by cross-sectional imaging. Cumulative incidence (CumI) of LR was calculated and a competing risks regression assessed factors associated with LR...
