Comparing patients who experienced at least one Clavien–Dindo grade ≥ IIIa complication (major morbidity) to those who did not (top), and patients who experienced a complication typically associated with a postoperative NS requirement to those who did not (bottom)

Comparisons were made using Fisher’s exact test. “Studied complications” included clinically relevant postoperative pancreatic fistula, bile leak, gastro-jejunal anastomotic leak, delayed gastric emptying, chyle leak, and postoperative ileus. Values are presented as number (%). Patients were excluded from the relevant sub-analyses where data were unavailable.

NS, nutritional support; EN, enteral nutrition; PN, parenteral nutrition.
