Hepatocellular carcinoma treatment over sorafenib: epigenetics, microRNAs and microenvironment. Is there a light at the end of the tunnel?

Introduction: Sorafenib is currently the only approved therapy in hepatocellular carcinoma (HCC). Alternative first- and second-line treatments are a significant unmet medical need, and several biologic agents have been tested in recent years, with poor results. Therefore, angiogenic pathways and the cytokine cascade remain possible targets in HCC.

Short- and medium-term outcomes of laparoscopic sleeve gastrectomy: a single center experience.

There are different surgical techniques adopted to treat morbid obesity. The objective of this study is to report surgical results after 20 laparoscopic sleeve gastrectomy (LSG) cases treated for morbid obesity during a 2-year follow-up and verify the effectiveness of LSG in term of Excess Weight Loss (EWL) as compared to laparoscopic adjustable gastric banding (LAGB).

Long-term maintenance of sustained virological response in liver transplant recipients treated for recurrent hepatitis C.

Aim: To investigate the long-term maintenance of sustained virological response in liver transplant recipients with hepatitis C recurrence.

Methods: 436 Liver transplant recipients (74.

Impact of pericardium bovine patch (Tutomesh(®)) on incisional hernia treatment in contaminated or potentially contaminated fields: retrospective comparative study.

Purpose: This retrospective comparative study analyzes the outcome of patients affected by incisional hernia in potentially contaminated or contaminated field, treated by three operative techniques.

Methods: 152 patients (62 M:90 F; mean age 65 ± 14 years) underwent incisional hernia repair (January 2002-January 2012) in complicated settings. Criteria of inclusion in the study were represented by the following causes of admission: mesh rejection/infection, obstruction without gangrene but with possible peritoneal bacterial translocation, obstruction with gangrene, enterocutaneous fistula or simultaneous presence of ileo- or colostomy.

Exhaled volatile organic compounds identify patients with colorectal cancer.

Background: An effective screening tool for colorectal cancer is still lacking. Analysis of the volatile organic compounds (VOCs) linked to cancer is a new frontier in cancer screening, as tumour growth involves several metabolic changes leading to the production of specific compounds that can be detected in exhaled breath. This study investigated whether patients with colorectal cancer have a specific VOC pattern compared with the healthy population.

A modified technique of pancreaticojejunostomy after pancreatoduodenectomy: a preliminary experience.

Pancreatoduodenectomy currently represents the treatment of choice for resectable pancreatic and periampullary malignant tumours, symptomatic chronic pancreatitis, duodenal cystic dystrophy, large adenomas, diverticula and benign periampullary tumours. Pancreato-jejunostomy failure remains the main complication following pancreatoduodenectomy, even leading to death. To improve the safety of this anastomosis, a modified technique of pancreato-jejunal anastomosis with posterior double-layer suture and Wirsung duct evagination is proposed.

The effects of weight loss due to gastric banding and lifestyle modification on red blood cell aggregation and deformability in severe obese subjects.

Objective: To investigate the changes in the aggregation index (AI) and the elongation index (EI), in severe obese subjects (MbObS) undergoing laparoscopic adjustable gastric banding (LAGB). AI and EI are measured by Laser assisted Optical Rotational Red Cell Analyzer (LORCA) and are markers of erythrocyte aggregation and deformability, respectively.

Design And Subjects: Before, 3 and 6 months after LAGB plus lifestyle changes (Mediterranean diet plus daily moderate exercise), we evaluated AI, EI, body mass index (BMI), total (ToT) cholesterol (Chol), high-density lipoprotein (HDL)-Chol, low-density lipoprotein (LDL)-Chol, triglycerides and fasting glucose and insulin levels in 20 MbObS.

Effects of olive oil polyphenols on fatty acid synthase gene expression and activity in human colorectal cancer cells.

Oleuropein (OL) and hydroxytyrosol (HT), the main olive oil polyphenols, possess anti-proliferative effects in vitro. Fatty acid synthase, a key anabolic enzyme of biosynthesis of fatty acids, plays an important role in colon carcinoma development. Our aim was to investigate whether gene expression of FAS, as well as its enzymatic activity, is regulated by HT and OL in two human colon cancer cell lines, as HT-29 and SW620.

Mucinous cystic neoplasm of the pancreas: a case report.

Cystic neoplasms of the pancreas account for only a small percentage of pancreatic tumours. They include mucinous cystic tumours, which have a higher incidence in females in their forties or fifties. Cystic neoplasms of the pancreas can present in a benign, borderline or malignant form.

Endoscopic management of large colorectal polyps.

Objectives: The optimal treatment for large colorectal polyps (LCPs) is still a controversial issue. The aim of this study was to evaluate the safety and effectiveness of endoscopic polypectomy (EP) of colorectal polyps >or=2 cm in size.

Patients And Methods: One hundred fifty-one EP LCPs were performed over a period of 7 years.

Basiliximab versus steroids in double therapy immunosuppression in liver transplantation: a prospective randomized clinical trial.

Background: : Basiliximab (B), an anti-CD25 monoclonal antibody, may represent an alternative to steroids (S) in immunosuppression after liver transplantation (LTx). The aim of this prospective randomized clinical trial was to compare B with S in a cyclosporin A (CsA)-based immunosuppression regimen in primary LTx.

Methods: : Forty-seven adult recipients of LTx were randomly assigned to receive B or S.

Single hepatocellular carcinoma ranging from 3 to 5 cm: radiofrequency ablation or resection?

Background: The optimal therapy for hepatocellular carcinoma (HCC) is transplantation. For all those patients not eligible for transplantation (or on the waiting list) among the treatments of choice used more frequently in recent years are resection (RES) and radiofrequency ablation (RFA). RFA is less efficacious for HCC ranging over 3 cm.

Fat depot-related differences in gene expression, adiponectin secretion, and insulin action and signalling in human adipocytes differentiated in vitro from precursor stromal cells.

Aim/hypothesis: The distinct metabolic properties of visceral and subcutaneous adipocytes may be due to inherent characteristics of the cells that are resident in each fat depot. To test this hypothesis, human adipocytes were differentiated in vitro from precursor stromal cells obtained from visceral and subcutaneous fat depots and analysed for genetic, biochemical and metabolic endpoints.

Methods: Stromal cells were isolated from adipose tissue depots of nondiabetic individuals.

Intragastric balloon and binge eating.

Background: In recent years, particular attention has been paid to the effect that eating disturbances and especially binge eating can have on the outcome of surgical treatments for obesity. Endoscopic positioning of the Bioenterics intragastric balloon (BIB) is mainly used in the work-up for surgical treatment of morbid obesity. Available data show that the BIB is a valid tool for reducing weight and co-morbidity, even if only a temporary treatment in morbidly obese patients.

Comparison of hemodynamic and respiratory effects of propofol and sevoflurane during carbon dioxide pneumoperitoneum in a swine model.

The aim of this study was to compare intraoperative hemodynamic and respiratory parameters using propofol and sevoflurane during laparoscopic surgery in a porcine model.

Randomized clinical trial of radiofrequency-assisted versus clamp-crushing liver resection.

Background: Surgical resection remains the treatment of choice for primary and secondary liver cancer. Complications are mainly related to blood loss. Radiofrequency-assisted liver resection (RF-R) has been proposed for parenchymal division as an alternative to clamp crushing in order to reduce blood loss.

Long-term functional assessment of antegrade colonic enema for combined incontinence and constipation using a modified Marsh and Kiff technique.

Purpose: Constipation and fecal incontinence can severely affect quality of life for patients, particularly when simultaneously present. Malone antegrade colonic enema enables periodic colonic emptying, thus preventing uncontrolled passage of feces and constipation.

Methods: Eleven patients with fecal incontinence and severe constipation or perineal colostomy after Miles' operation underwent a modified Marsh and Kiff ileostomy for antegrade colonic enema.

Tissue factor and vascular endothelial growth factor expression in colorectal cancer: relation with cancer recurrence.

Objective: This study was undertaken to quantify tissue factor (TF) and vascular endothelial growth factor (VEGF) in colorectal cancer and to evaluate their possible relationship with recurrence.

Method: TF and VEGF were measured by enzyme-linked immunosorbent assay in surgical tumour specimens and normal mucosa from 50 consecutive patients with colorectal cancer who were followed up for 3 years for the assessment of disease recurrence.

Results: TF and VEGF antigens were detected in all tumour samples.

The Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS) A retrospective review of 379 patients undergoing laparoscopic splenectomy.

In December 2000, the Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS) was formally launched under the auspices of the Italian Society for Endoscopic Surgery and New Technologies (SICE). The aim of this multicentre study was to analyse various aspects of the treatment that are still under discussion, such as the extension of the laparoscopic indications in cases of malignancy, independently of the associated splenomegaly, patient selection and operative techniques. A retrospective review of 379 patients undergoing laparoscopic splenectomy for haematological diseases from February 1, 1993, to September 15, 2005, was conducted.
