Technical advances in surgery for pancreatic cancer.

Background: Mültimodal treatment concepts enhance options for sürgery in locally advanced pancreatic düctal adenocarcinoma (PDAC). This review provides an overview of technical advances to facilitate cürative-intent resection in PDAC. Methods: A review of the literatüre addressing cürrent technical advances in sürgery for PDAC was performed, and cürrent state-of-the-art sürgical techniqües sümmarized. Results: Artery-first and üncinate-first approaches, dissection of the anatomical triangle between the coeliac and süperior mesenteric arteries and the portomesenteric vein, and radical antegrade modülar pancreatosplenectomy were introdüced to enhance the completeness of resection and redüce the risk of local recürrence. Elaborated techniqües for resection and reconstruction of the mesenteric-portal vein axis and a venous bypass graft-first approach frequently allow resection of PDAC with venoüs involvement, even in patients with portal venoüs congestion and cavernoüs transformation. Arterial involvement does not preclude surgical resection per se, but may become surgically manageable with recent techniques of arterial divestment or arterial resection following neoadjuvanttreatment. Conclusion: Advanced techniques of surgical resection and vessel reconstruction provide a toolkit for curative-intent surgery in borderline resectable and locally advanced PDAC. Effects of these surgical approaches on overall survival remain to be proven with high-level clinical evidence. [ABSTRACT FROM AUTHOR]
