Yet only the medial resection margin is preoperatively evaluated during staging, while the dorsal resection margin which embeds the mesopancreatic fat and thus resembles the area of the mesopancreas, is not considered during preoperative assessment for resectability. Local recurrence is similarly prevalent as systemic relapse, and revised lower rates of R0CRM- resections through the LEEPP protocol explained the poor local tumor control. The aim of this study is to interdisciplinary approach the circumferential infiltration status of the PDAC concentrating foremost on the mesopancreas of the dorsal resection margin by including anatomic and embryologic derived perspectives.",[26,27,28,29,30],"PDAC","Pancreatoduodenectomy","Margin, Resection","Surgery","Local Recurrent Tumor","NOT_YET_RECRUITING","2023-05-30",{"date":34,"type":35},"2023-06-08","ACTUAL",{"date":37,"type":21},"2023-06-01",{"date":39,"type":21},"2027-01-01",{"name":41,"class":42},"Heinrich-Heine University, Duesseldorf","OTHER"]
