Abstract
Introduction: Pancreatic malignant tumors are resectable at diagnosis in only 15% to 20% of cases and invasion of vascular structures is commonly present. Therefore, extended resections are needed for adequate local control and negative margins. However, morbidity and mortality associated with these enlarged resections are limiting factors. The aim of this study was to correlate demographic and technical aspects that influenced early and late outcomes.Materials and Methods: Between October 2007 and May 2019, 523 pancreatic surgeries were performed, of which 72 required vascular resections. Clinical and histopathological data, surgical techniques, and perioperative parameters were analyzed in a prospectively collected database.Results: Of the 72 cases of vascular resection, 31 were male and 41 females with a mean age of 60.9 years (34‐81). The most commonly affected vascular structure was the portal vein (in 40.3%). Free margins were obtained in 77.8% of cases. Postoperative mortality rate at 60 days was 13.9%. American Society of Anesthesiologists (ASA) and age were the most important predictors of major complications.Conclusion: Extended resections with vascular involvement in pancreatic surgeries are feasible and safe; furthermore, patient selection plays are key. ASA and age were the most important factors in the decision‐making process for extended resections.
