The primary endpoint of this study was to analyze the trend of ALPPS in Italy over a 10-year period. The secondary endpoint was to evaluate factors affecting the risk of morbidity/mortality/post-hepatectomy liver failure (PHLF).

The impact of COVID-19 pandemic on a tertiary referral proctology center: no one should be left behind.

Background: Coronavirus disease 2019 (COVID-19) has disrupted healthcare delivery. We aimed to describe a novel strategy to mitigate the impact of COVID-19 pandemic on a tertiary referral proctology center during the first wave of infection in Italy.

Methods: All patients booked appointments at the Proctology Unit between March 9 and May 4, 2020 were identified.

The Italian Consensus on minimally invasive simultaneous resections for synchronous liver metastasis and primary colorectal cancer: A Delphi methodology.

At the time of diagnosis synchronous colorectal cancer, liver metastases (SCRLM) account for 15-25% of patients. If primary tumour and synchronous liver metastases are resectable, good results may be achieved performing surgical treatment incorporated into the chemotherapy regimen. So far, the possibility of simultaneous minimally invasive (MI) surgery for SCRLM has not been extensively investigated.

Liver resection for perihilar cholangiocarcinoma: Impact of biliary drainage failure on postoperative outcome. Results of an Italian multicenter study.

Background: Preoperative biliary drainage may be essential to reduce the risk of postoperative liver failure after hepatectomy for perihilar cholangiocarcinoma. However, infectious complications related to preoperative biliary drainage may increase the risk of postoperative mortality. The strategy and optimal drainage method continues to be controversial.

Minimally Invasive Stage 1 to Protect Against the Risk of Liver Failure: Results from the Hepatocellular Carcinoma Series of the Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy Italian Registry.

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has been described to treat hepatocellular carcinoma (HCC) but burdened, in its pioneering phase, by high morbidity and mortality. With the advent of minimally invasive (MI) techniques in liver surgery, surgical complications, including posthepatectomy liver failure (PHLF), have been dramatically reduced. The primary endpoint of this study was to compare the short-term outcomes of MI- versus open-ALPPS for HCC, with specific focus on PHLF.

Outcomes of enhanced one-stage ultrasound-guided hepatectomy for bilobar colorectal liver metastases compared to those of ALPPS: a multicenter case-match analysis.

Background: In case of bilobar colorectal liver metastases (CLM) associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has been proposed. Enhanced one-stage ultrasound-guided hepatectomy (e-OSH) may represent a further solution for these patients. Aim of this study was to compare by case-match analyses the outcome of ALPPS and e-OSH.

Retrospective Comparison of Single-Port Sleeve Gastrectomy Versus Three-Port Laparoscopic Sleeve Gastrectomy: a Propensity Score Adjustment Analysis.

Purpose: Evaluate the efficacy of single-port sleeve gastrectomy (SPSG) and then compare it to a less-invasive sleeve approach (three-port) (3PSG) according to a propensity score (PS) matching analysis.

Materials And Methods: We analyzed all patients who underwent SG through a three-port or a single-port laparoscopic approach.

Results: After 2 years, the follow-up was completed in 84% patients treated with 3PSG and 95% patients of the SPSG group.

Quantitative Imaging Features and Postoperative Hepatic Insufficiency: A Multi-Institutional Expanded Cohort.

Background: Post-hepatectomy liver insufficiency (PHLI) is a significant cause of morbidity and mortality after liver resection. Quantitative imaging analysis using CT scans measures variations in pixel intensity related to perfusion. A preliminary study demonstrated a correlation between quantitative imaging features of the future liver remnant (FLR) parenchyma from preoperative CT scans and PHLI.

Blood transfusions and steatohepatitis are independent risk factors for complications following liver resection for colorectal cancer liver metastases.

The aim of the present study was to evaluate the risk factors for postoperative complications following liver resection for colorectal cancer liver metastases. Patients who underwent hepatic resection for colorectal cancer liver metastases were stratified according to chemotherapy administration and body mass index (BMI) to eliminate potential confounding factors. A univariate analysis was conducted to identify potential risk factors for postoperative complications following liver resection.

Gastrointestinal stromal tumour (GIST) presenting as a strangulated inguinal hernia with small bowel obstruction.

Gastrointestinal stromal tumours (GISTs) can arise everywhere along the gastrointestinal (GI) tract. Their presentation in unusual locations should always be taken into account. A 74-year-old man referred to the emergency department for small bowel obstruction caused by an incarcerated inguinal hernia.

The role of adipose stem cells in inflammatory bowel disease: From biology to novel therapeutic strategies.

Inflammatory bowel diseases are an increasing phenomenon in western countries and in growing populations. The physiopathology of these conditions is linked to intestinal stem cells homeostasis and regenerative potential in a chronic inflammatory microenvironment. Patients with IBD present an increased risk of developing colorectal cancer (CRC), or colitis associated cancer (CAC).

From Inflammation to Cancer in Inflammatory Bowel Disease: Molecular Perspectives.

Inflammatory bowel diseases (IBD) are associated with an increased risk of colitis-associated colorectal carcinoma (CAC). CAC is one of the most important causes of morbidity and mortality in patients with Crohn's disease and ulcerative colitis. The aim of the present review was to discuss the most important signaling pathways and genetic alterations involved in carcinogenesis related to IBD, focusing on the molecular aspects of cancer stem cell physiology and the impact of the inflammatory microenvironment.

Suture With Resorbable Cones: Histology and Physico-Mechanical Features.

Background: Silhouette Sutures (Kolster Methods, Inc., Corona, CA) exhibit different biological characteristics at various time points after their placement.

Objectives: The goals of this study were to understand the biological reactions of Silhouette Sutures in human tissues at different time intervals and to determine the index of resistance of the sutures in subcutaneous tissue.

Isolation and characterization of biliary epithelial and stromal cells from resected human cholangiocarcinoma: a novel in vitro model to study tumor-stroma interactions.

Cholangiocarcinoma (CCA) is a devastating malignancy arising from the bile ducts. Cancer-associated fibroblasts (CAFs) are key players in CCA invasiveness and in the generation of a desmoplastic reaction. The aim of the present study was to develop a novel model by which to study tumor-stroma interactions using primary cultures of human biliary epithelial cells (hBECs) and stromal cells (SCs) in CCA.

The biology of epidermal growth factor receptor and its value as a prognostic/predictive factor.

Receptor tyrosine kinases play a major role in human carcinogenesis. Overexpression of the epidermal growth factor receptor (EGFR) has been associated with poor clinical outcome in several types of cancer. In principle, as with HER2, the EGFR status of a tumor should predict the likelihood of response to EGFR-targeted therapy.

Malignant progression in pleomorphic xanthoastrocytoma: personal experience and review of the literature.

Pleomorphic xanthoastrocytoma (PXA) is a rare primary low-grade astrocytic tumor, recently classified as a neuroglial tumor. It generally occurs in children and young adults and shows benign behaviour (WHO II), although an anaplastic variant and malignant potential have been described. Pleomorphic xanthoastrocytomas with malignant transformation have been reported in three out of eight patients operated on for this type of tumor in our department in the last 15 years.

Assessing epidermal growth factor receptor expression in tumours: what is the value of current test methods?

Over-expression of the epidermal growth factor receptor (EGFR) in tumours is associated with aggressive disease and poor clinical prognosis. In theory, the EGFR status of a tumour provides an indication of the likelihood of response to EGFR-targeted therapy. However, the clinical data do not support a relationship between EGFR expression and response to EGFR-targeted therapies cetuximab, gefitinib and erlotinib.
