The Pancreatic Adenocarcinoma (PA) is estimated to become the second leading cancer-related death cause by 2030. At the time of diagnosis, 30% of patients have a locally advanced disease especially vascular involvement Performed firstly in 1973; the benefits of vein resection on survival have been clearly demonstrated by published reports

Dissecting esophagitis is a rare and benign form of chronic esophagitis, of diverse etiology, char- acterized by a typically whitish mucosa, with or without bleeding and presence of vertical circum- ferential fissures and cracks at endoscopy

Chromoendoscopic technique dates to 1970, when various dyes were used on the tissue lining the GI tract to detect subtle lesions that are hard to detect using normal endoscopic imaging. Applied colour enhances tissue characterisation thus providing easier identification of pathological con- dition
