Background: The Coronavirus 2019 (COVID-19) pandemic has favored the growth of telemedicine systems and in this context the idea of Metaverse was born and developed. A 3D reality in which people can interact with each other through digital reproductions of themselves. Metaverse has already been tested in numerous medical fields due to its ability to combine visual and auditory information with tactile sensations.

Robotic Distal Pancreatectomy Yields Superior Outcomes Compared to Laparoscopic Technique: A Single Surgeon Experience of 123 Consecutive Cases.

Technical limitations of laparoscopic distal pancreatectomy (LDP), in comparison to robotic distal pancreatectomy (RDP), may translate to high conversion rates and morbidity. LDP and RDP procedures performed between December 2008 and January 2023 in our tertiary referral hepatobiliary and pancreatic centres were analysed and compared with regard to short-term outcomes. A total of 62 consecutive LDP cases and 61 RDP cases were performed.

Laparoscopic versus robotic abdominal and pelvic surgery: a systematic review of randomised controlled trials.

Background: The current evidence is inconclusive on whether robotic or laparoscopic surgery is the optimal platform for minimally invasive surgery. Existing comparisons techniques focus on short-term outcomes only, while potentially being confounded by a lack of standardisation in robotic procedures. There is a pertinent need for an up-to-date comparison between minimally invasive surgical techniques.

Hepatic epithelioid hemangioendothelioma (HEHE)-rare vascular malignancy mimicking cholangiocarcinoma: a case report.

Hepatic epithelioid hemangioendothelioma (HEHE) is a rare, often misdiagnosed malignancy of vascular origin. We describe a case of a 36-year-old, who presented with a burning sensation in his chest on exercise and was believed to have bilobar intrahepatic cholangiocarcinoma. After receiving chemotherapy with partial response, the patient underwent staged resection with modified associating liver partition with portal vein ligation for staged hepatectomy (ALPPS) procedure-laparoscopic radiofrequency-assisted ALPPS (RALPPS).

Artificial intelligence in the detection, characterisation and prediction of hepatocellular carcinoma: a narrative review.

Hepatocellular carcinoma (HCC) is a significant cause of morbidity and mortality worldwide. Despite significant advancements in detection and treatment of HCC, its management remains a challenge. Artificial intelligence (AI) has played a role in medicine for several decades, however, clinically applicable AI-driven solutions have only started to emerge, due to gradual improvement in sensitivity and specificity of AI, and implementation of convoluted neural networks.

Pancreatic Incidentalomas on CT Colonography: Ignore, Follow up or Investigate?

Increasing use of cross-sectional abdominal imaging such as CT colonography (CTC), has resulted in increased identification of incidental pancreatic cystic lesions. Such incidental findings are a cause for anxiety amongst patients and clinicians and can result in increased cost to healthcare delivery resultant from referral to subsequent investigations. Our study explored the prevalence of incidental cystic pancreatic lesions on CTC at a tertiary pancreatic centre, and their management.

Can we predict the progression of premalignant pancreatic cystic tumors to ductal adenocarcinoma?

Pancreatic ductal adenocarcinoma (PDAC) is the most prevalent malignant pancreatic tumor. Few studies have shown how often PDACs arise from cystic precursor lesions. This special report aims to summarize the evidence on the progression of precancerous lesions to PDAC.

The Atlantic divide: contrasting surgical robotics training in the USA, UK and Ireland.

The uptake of robotic surgery is rapidly increasing worldwide across surgical specialties. However, there is currently a much higher use of robotic surgery in the United States of America (USA) compared to the United Kingdom (UK) and Ireland. Reduced exposure to robotic surgery in training may lead to longer learning curves and worse patient outcomes.

Quality of life after pancreatic surgery - A systematic review.

Background: Surgery for patients with pancreatic cancer carries a high risk of major post-operative complications and only marginally improves overall survival. This review aims to assess the impact of surgical resection on health-related quality of life (HRQOL) of pancreatic cancer patients.

Methods: A systematic review of the literature was performed according to the PRISMA guidelines.

Clinical utility of clonal origin determination in managing recurrent hepatocellular carcinoma.

Introduction: Recurrence is the driving factor for reduced long-term survival in patients following resected hepatocellular carcinoma (HCC). Extensive research efforts have been conducted to understand the molecular processes precipitating disease recurrence. Modern genomic techniques have identified two distinct mechanisms for recurrent HCC (RHCC): Intrahepatic metastasis (IM-HCC); and multicentric origin (MO-HCC).

A Comprehensive Patient and Public Involvement Program Evaluating Perception of Cannabis-Derived Medicinal Products in the Treatment of Acute Postoperative Pain, Nausea, and Vomiting Using a Qualitative Thematic Framework.

Cannabis-derived medicinal products (CDMPs) have antiemetic properties and in combination with opioids have synergistic analgesic effects in part signaling through the delta and kappa opioid receptors. The objective of this patient and public involvement program was to determine perception of perioperative CDMPs in our local population to inform design of a clinical trial. A qualitative evaluation was conducted utilizing a focus group, semistructured interviews and a community event.

A better route to ALPPS: minimally invasive vs open ALPPS.

Background: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has gained both interest and controversy, as an alternative to portal vein embolisation (PVE) by inducing future liver remnant hypertrophy in patients at risk of liver failure following major hepatectomy. Open ALPPS induces more extensive hypertrophy in a shorter timespan than PVE; however, it is also associated with higher complication rates and mortality. Minimally invasive surgery (MIS), with its known benefits, has been applied to ALPPS in the hope of reducing the surgical insult and improving functional recovery time while preserving the extensive FLR hypertrophy.

Transition from open and laparoscopic to robotic pancreaticoduodenectomy in a UK tertiary referral hepatobiliary and pancreatic centre - Early experience of robotic pancreaticoduodenectomy.

Background: Pancreaticoduodenectomy is performed using an open technique (OPD) as the gold standard. An increase in those performed laparoscopically (LPD) and robotically (RPD) are now reported. We compared the short-term outcomes of RPD cases with LPD and OPD.

Rapid Induction of Liver Regeneration for Major Hepatectomy (REBIRTH): A Randomized Controlled Trial of Portal Vein Embolisation versus ALPPS Assisted with Radiofrequency.

To avoid liver insufficiency following major hepatic resection, portal vein embolisation (PVE) is used to induce liver hypertrophy pre-operatively. Associating liver partition with portal vein ligation for staged hepatectomy assisted with radiofrequency (RALPPS) was introduced as an alternative method. A randomized controlled trial comparing PVE with RALPPS for the pre-operative manipulation of liver volume in patients with a future liver remnant volume (FLRV) ≤25% (or ≤35% if receiving preoperative chemotherapy) was conducted.

Can we predict long-term survival in resectable pancreatic ductal adenocarcinoma?

Objective: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive tumour associated with poor 5-year survival. We aimed to determine factors which differentiate short and long-term survivors and identify a prognostic biomarker.

Methods: Over a ten-year period, patients with resected PDAC who developed disease recurrence within 12 months (Group I) and those who had no disease recurrence for 24 months (Group II) were identified.

Circulating Tumor Cells and Cell-Free DNA in Pancreatic Ductal Adenocarcinoma.

Pancreatic cancer is detected late in the disease process and has an extremely poor prognosis. A blood-based biomarker that can enable early detection of disease, monitor response to treatment, and potentially allow for personalized treatment would be of great benefit. This review analyzes the literature regarding two potential biomarkers, circulating tumor cells (CTCs) and cell-free DNA (cfDNA), with regard to pancreatic ductal adenocarcinoma.

A totally laparoscopic associating liver partition and portal vein ligation for staged hepatectomy assisted with radiofrequency (radiofrequency assisted liver partition with portal vein ligation) for staged liver resection.

In order to induce liver hypertrophy to enable liver resection in patients with a small future liver remnant (FLR), various methods have been proposed in addition to portal vein embolisation (PVE). Most recently, the associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) technique has gained significant international interest. This technique is limited by the high morbidity associated with an in situ liver splitting and the patient undergoing two open operations.

Laparoscopic long sleeve pancreaticogastrostomy (LPG): a novel pancreatic anastomosis following central pancreatectomy.

Background: Central pancreatectomy (CP) is preferred to distal pancreatectomy (DP) for the excision of benign tumours at the neck or body of the pancreas, in order to preserve pancreatic function and the spleen. However, the pancreaticoenterostomy is technically difficult to perform laparoscopically and the postoperative pancreatic fistula (POPF) rate is high.

Methods: A novel laparoscopic reconstruction of the pancreatic stump during CP is described, the laparoscopic long sleeve pancreaticogastrostomy (LPG).
