Purpose: To assess the association between neoadjuvant therapy and overall survival (OS) in patients with left-sided resectable pancreatic cancer (RPC) compared to upfront surgery. Background: Left-sided pancreatic cancer is associated with worse OS compared to right-sided pancreatic cancer. Although neoadjuvant therapy is currently seen as not ef...

PURPOSE The benefit of adjuvant therapy for intraductal papillary mucinous neoplasm (IPMN)-derived pancreatic ductal adenocarcinoma (PDAC) remains unclear because of severely limited evidence. Although biologically distinct entities, adjuvant therapy practices for IPMN-derived PDAC are largely founded on pancreatic intraepithelial neoplasia-derived...

Simple Summary Elderly cancer patients represent a population particularly susceptible to nutritional alterations, which can have an impact on overall survival and chemotherapy tolerance. The effects of nutritional interventions in this frail population have not been adequately examined in previous review studies. We conducted a systematic review o...

The journal Artificial Intelligence Surgery was established to explore the integration of Artificial Intelligence (AI) in surgery. It originated from the desire to understand the potential of true robotic surgery, as existing robotic systems are tele-manipulators rather than autonomous robots. AI’s role in surgery involves levels of autonomy and a...

The ethics were divided into 6 topic...

Purpose The role of supplemental artificial nutrition in patients perioperatively treated according to enhanced recovery programs (ERAS) on surgery-related morbidity is not known. Therefore, there is a need of a clinical trials specifically designed to explore whether given a full nutritional requirement by parenteral feeding after surgery coupled...

Background: When treating potentially resectable pancreatic adenocarcinoma, therapeutic decisions are left to the sensibility of treating clinicians who, faced with a decision that post hoc can be proven wrong, may feel a sense of regret that they want to avoid. A regret-based decision model was applied to evaluate attitudes toward neoadjuvant the...

Background: Shared decision-making (SDM) between clinicians and patients is one of the pillars of the modern patient-centric philosophy of care.

Background: Artificial intelligence (AI) is gaining traction in medicine and surgery. AI-based applications can offer tools to examine high-volume data to inform predictive analytics that supports complex decision-making processes. Time-sensitive trauma and emergency contexts are often challenging. The study aims to investigate trauma and emergenc...

Background Preoperative FOLFIRINOX chemotherapy is increasingly administered to patients with borderline resectable (BRPC) and locally advanced pancreatic cancer (LAPC) to improve overall survival (OS). Multicenter studies reporting on the impact from the number of preoperative cycles and the use of adjuvant chemotherapy in relation to outcomes in...

Pancreatic ductal adenocarcinoma (PDAC) is currently the most deadly cancer. Although characterized by 5–20% of neoplastic cells in the highly fibrotic stroma, immunotherapy is not a valid option in PDAC treatment. As CXCR4-CXCL12 regulates tumor invasion and T-cell access and PD-1/PD-L1 controls immune tolerance, 76 PDACs were evaluated for CXCR4-...

Background This study aimed to discuss and report the trend, outcomes, and learning curve effect after minimally invasive distal pancreatectomy (MIDP) at two high-volume centres. Methods Patients undergoing MIDP between January 1999 and December 2018 were retrospectively identified from prospectively maintained electronic databases. The entire coh...

We herein updated a previous case series to investigate the oncologic outcomes and preoperative factors that could drive the decision-making process.Methods This retrospective analysis was limited...

Objective This study aims to summarize the evidence concerning the barriers that exist to the career progression of women in surgery and to provide potential solutions to overcome these obstacles. Background Visible and invisible impediments can hinder female doctors’ pursuit of a surgical career, from choosing a surgical specialty to training opp...

Introduction: Pancreatic cancer requires a multidisciplinary approach in a high-volume center for all the steps of the diagnostic-therapeutic course. However, the most experienced centers are not evenly distributed throughout the country causing a real "health migration" that involves patients and families with relevant economic, time, and energy c...

SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients.Since surgical patients are already at higher risk of venous thromboembolism than general populations, thisstudy aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk ofvenous thromboembolism. We...

Most surgeons are skeptical as to the feasibility of autonomous actions in surgery. Interestingly, many examples of autonomous actions already exist and have been around for years. Since the beginning of this millennium, the field of artificial intelligence (AI) has grown exponentially with the development of machine learning (ML), deep learning (D...

Background In 2019, women accounted for 46% of surgical residents. Despite the international debate on gender disparities, no literature regarding the experience in Italy is available. The aim of this survey study was to assess satisfaction among female surgeons in Italy, and whether they encounter gender-based discrimination. Study design An anon...

Introduction: Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive tumor types and the 4th leading cause of tumor-related mortality in developed nations. PDAC is characterized by a highly fibrotic stroma that can physically exclude cytotoxic T cells from the vicinity of tumor cells. Targeting the axis CXCR4-CXCL12 improved T cell a...
