Long-term outcomes of transarterial embolization with lipiodol-bleomycin emulsion plus polyvinyl alcohol particles versus the particles alone for large symptomatic focal nodular hyperplasia: a propensity score-matched analysis.

Objectives: To compare the efficacy of transarterial embolization (TAE) with polyvinyl alcohol (PVA) particles alone and lipiodol-bleomycin emulsion (LBE) plus PVA particles for patients with unresectable large symptomatic focal nodular hyperplasia (FNH).

Methods: We performed a retrospective analysis of patients who underwent TAE either with PVA particles alone (group A, n = 46) or LBE plus PVA particles (group B, n = 35) for large (≥ 7 cm) symptomatic FNH between January 2002 and February 2019. Propensity score matching (PSM) (1:1) was performed to adjust for potential baseline confounders.

Effect of Huaier granule on recurrence after curative resection of HCC: a multicentre, randomised clinical trial.

Objective: There is little evidence that adjuvant therapy after radical surgical resection of hepatocellular carcinoma (HCC) improves recurrence-free survival (RFS) or overall survival (OS). We conducted a multicentre, randomised, controlled, phase IV trial evaluating the benefit of an aqueous extract of Murr (Huaier granule) to address this unmet need.

Design And Results: A total of 1044 patients were randomised in 2:1 ratio to receive either Huaier or no further treatment (controls) for a maximum of 96 weeks.

Ultrasound-guided radiofrequency ablation of the segmental Glissonian pedicle: A new technique for anatomic liver resection.

Background: Anatomic liver resection is widely accepted as the optimal surgical treatment for hepatocellular carcinoma (HCC); however, the complexity of conventional operative methods limits their use. To explore the possibility of using modern techniques to achieve a simpler approach, we have evaluated ultrasound-guided segmental radiofrequency ablation (RFA) of the Glissonian pedicle before liver resection in a porcine model and in HCC patients.

Methods: This study had 2 stages.

A New Segmental Hepatectomy Approach Using Ultrasound-Guided Portal Branch Infusion of a Thermosensitive Gel in Pigs.

Background: The aim of this study was to evaluate the safety, feasibility, and efficacy of a new segmental hepatectomy (SH) approach using intraoperative ultrasound (IOUS) guided infusion of a reversible thermosensitive gel into the portal vein branch in pigs;

Materials And Methods: Poloxamer 407 aqueous solution (20%, W/V) was mixed with indocyanine green (P407-ICG) in this study to make it green, and it remained liquid at room temperature and turned into a firm gel upon reaching body temperature. In experiment I, six pigs were used to detect the outcome of infusing the mixture into the biliary tract, liver parenchyma, and hepatic vein for a safety study. In experiment II, another 12 pigs were randomly segmented into two groups [SH group and partial hepatectomy (PH) group] to investigate the feasibility and efficacy of the new approach using IOUS-guided infusion of the mixture into the portal branch;

Results: No thermosensitive gel-induced abnormal changes were observed in the safety study.

Comparison analysis in synchronous and metachronous metastatic colorectal cancer based on microarray expression profile.

Background/aims: Colorectal cancer (CRC) is one of the most common malignancies, and liver metastasis is one of the major causes of death of CRC. This study aimed to compare the genetic difference between metachronous lesions (MC) and synchronous lesions (SC) and explore the molecular pathology of CRC metastasis.

Methodology: Microarray expression profile data (GSE10961) including 8 MC and 10 SC was downloaded from Gene Expression Omnibus.

Double stranded RNA-dependent protein kinase promotes the tumorigenic phenotype in HepG2 hepatocellular carcinoma cells by activating STAT3.

Previously known as a first-response protein upon viral infection and other stress signals, double-stranded RNA-dependent protein kinase (PKR, also termed EIF2AK2) has been found to be differentially expressed in multiple types of tumor, including hepatocellular carcinoma, suggesting that PKR may be involved in tumor initiation and development. However, whether and how PKR promotes or suppresses the development of hepatocellular carcinoma remains controversial. In the present study, PKR expression was investigated using qPCR and western blot analysis, which revealed that PKR expression was upregulated in liver tumor tissues, when compared to that of adjacent normal tissues, which were obtained from four primary liver cancer patients.

Risk factors of delayed gastric emptying following pancreaticoduodenectomy.

Background: This study aims to explore the morbidity and risk factors of delayed gastric emptying (DGE) following pancreaticoduodenectomy.

Methods: Between 1 January 2013 and 31 December 2013, data from 196 consecutive patients who underwent pancreaticoduodenectomy in the Chinese PLA General Hospital were recorded retrospectively. A total of 17 factors were examined with univariate analysis, and multivariate logistic regression analysis was used to estimate relative risks.

Effects of intensive insulin therapy combined with low molecular weight heparin anticoagulant therapy on severe pancreatitis.

Comprehensive application of modern technologies in precise liver resection.

Background: Liver surgery has gone through the phases of wedge liver resection, regular resection of hepatic lobes, irregular and local resection, extracorporeal hepatectomy, hemi-extracorporeal hepatectomy and Da Vinci surgical system-assisted hepatectomy. Taking advantage of modern technologies, liver surgery is stepping into an age of precise liver resection. This review aimed to analyze the comprehensive application of modern technologies in precise liver resection.

Papillary carcinoma of the duodenum combined with right renal carcinoma: a case report.

We report a case of papillary carcinoma of the duodenum combined with right renal carcinoma. A 58-year-old man underwent a physical examination that revealed intrahepatic and extrahepatic bile duct dilatation on B ultrasound. Intrahepatic bile duct dilatation could be seen on magnetic resonance imaging (MRI), but the head of the pancreas and distal bile duct showed no tumor signals, which led to a diagnosis of periampullary carcinoma and right renal carcinoma.

A meta-analysis of the long-term effects of chronic pancreatitis surgical treatments: duodenum-preserving pancreatic head resection versus pancreatoduodenectomy.

Background: Surgery is regarded as the most effective treatment to relieve pain and reduce complications in chronic pancreatitis (CP). Two major strategies exist: duodenum-preserving pancreatic head resection (DPPHR) and pancreatoduodenectomy (PD). Many studies suggest that DPPHR offers advantages during surgery and in the short-term; however, the long-term effects have not been thoroughly investigated.

Preserving hepatic artery flow during portal triad blood inflow occlusion improves remnant liver regeneration in rats after partial hepatectomy.

Background: In the present study, we compared preservation of the hepatic artery flow during liver blood inflow occlusion with total portal triad blood flow clamping (the Pringle maneuver) to examine their effects on liver regeneration in rats after partial hepatectomy.

Materials And Methods: Male Wistar rats were randomized to a control group (without hepatic inflow occlusion), an occlusion of the portal triad (OPT) group (OPT for 30 min under portal blood bypass), and an occlusion of the portal vein (OPV) group (OPV only for 30 min under portal blood bypass). All the rats underwent partial hepatectomy at the end of hepatic blood control.

[Effects of different hepatic inflow occlusion methods on liver regeneration following partial hepatectomy in rats].

Objective: To explore the effects of different hepatic inflow occlusion methods on liver regeneration in rats after partial hepatectomy (PH).

Methods: Male Wistar-Furth rats were randomly assigned to three groups: control group, underwent 68% hepatectomy alone; occlusion of portal triad (OPT) group, subjected to occlusion of portal triad under portal blood bypass; and occlusion of portal vein (OPV) group, subjected to occlusion of portal vein under portal blood bypass. Blood flow was occluded for 20, 30, and 40 minutes before 68% hepatectomy.

Prognostic significance of mast cell count following curative resection for pancreatic ductal adenocarcinoma.

Background: Recently, there is evidence that the number of mast cells in various solid cancers increases with tumor progression. The role of mast cells in promoting tumor progression, however, has not been well studied in pancreatic ductal adenocarcinoma (PDAC). The aim of this study was to investigate the prognostic value of mast cell counts in different zones of the neoplasm in patients with PDAC after curative resection.
