Pancreas-visceral fat CT value ratio and serrated pancreatic contour are strong predictors of postoperative pancreatic fistula after pancreaticojejunostomy

Parenchymal thickness = the thickness of the pancreas (mm) - MPD diameter (mm), at the planned cut line
^aThis case underwent SSPPD, transverse colectomy and low anterior resection for triple cancer (duodenal papilla, transverse colon and rectum)
^bThis case developed intraoperative massive bleeding due to the presence of intraabdominal abscess and severe adhesion to adjacent organs and vessels, but finally recovered
