Pancreatic cancer (PC) ranks as the seventh leading cause of cancer-related deaths, with approximately 500,000 new cases reported in 2020. Existing strategies for early PC detection primarily target individuals at high risk of developing the disease. Nevertheless, there is a pressing need to identify innovative clinical approaches and personalized treatments for effective PC management.

The efficacy and safety of pancreaticoduodenectomy (PD) has not been yet studied in octogenarians in Greece. The present study reviewed records of all consecutive patients that underwent PD at the 4th Surgical Department of Attikon University Hospital (Athens, Greece) between January 1st, 2010 and December 31st, 2019. Differences between two age groups (group Y <80 years; group O >80 years) were analyzed.

The mesentery constitutes a common location for the metastatic spread of malignant gastrointestinal tumors. Primary mesenteric tumors, on the other hand, are very rare; lymphomas are the most common, followed by benign and malignant mesenchymal tumors. We present a case of a 43-year-old patient operated on for a primary mesenteric leiomyosarcoma with a positive immunostain for DOG1, despite having no or mutations on molecular analysis.

Article Synopsis
  • The study investigates postoperative pancreatic fistula (POPF) rates in patients who underwent pancreaticoduodenectomy, comparing two gut restoration techniques: a single jejunal loop and a Roux-en-Y configuration.
  • The analysis of 415 patients revealed that those with the Roux-en-Y technique had significantly lower POPF rates (12.1% and 9.4%) compared to the single jejunal loop group (19%).
  • The findings suggest that the Roux-en-Y method effectively reduces the activity of pancreatic enzymes, thereby decreasing the severity and incidence of complications related to POPF.

COVID-19 pandemic has obviously affected patients' behavior towards seeking medical help as well as physicians' decision in the management of emergencies. Our recent experience as surgeons at a COVID-19 referral hospital revealed cases which share an alerting characteristic: the delay in appropriate management. Unfortunately for COVID-19 negative patients a "coronacentric" health system has been adopted.

Although pancreaticoduodenectomy (PD) has significantly improved and is considered a safe procedure, it is still associated with increased rates of morbidity. The aim of the present study is to evaluate an alternative reconstruction technique following PD. This technique uses an isolated hepaticojejunal anastomosis and presents low postoperative morbidity rates.

Background: Intraoperative use of specialized equipment and disposables contributes to the increasing cost of modern liver surgery. As a response to the recent severe financial crisis in our country we have employed a highly standardized protocol of liver resection that minimizes intraoperative and postoperative costs. Our goal is to evaluate cost-effectiveness of this protocol.

Right trisectionectomy for posterior liver tumors engaging the right and middle hepatic veins may lead to post-hepatectomy liver failure if the anticipated liver remnant is small. In such patients we developed a parenchyma-sparing one-step approach, that includes extrahepatic right portal vein ligation accompanied by en bloc resection only of segments 7, 8 and 4a and resection of the right and middle hepatic veins. The technique was applied in 3 patients with normal liver function, where according to the preoperative computed tomography the volume of segments 1, 2 and 3 ranged between 17% and 20% of the total liver volume.

Background: Treatment of peripherally located liver tumors with diaphragmatic invasion is technically demanding but does not preclude resection for cure. The aim of the present study was to compare patients undergoing combined liver and diaphragmatic resection with those submitted to hepatectomy alone so as to evaluate the safety, effectiveness, and value of this complex surgical procedure.

Methods: From January 2000 to September 2011, 36 consecutive patients underwent en bloc liver-diaphragm resection (group A).
