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
