Values in parentheses are percentages unless indicated otherwise; *values are median (range). PV, portal vein. SMV, superior mesentery vein. LOS, length of stay. † Including one delayed gastric emptying and one peri-pancreatic fluid accumulation with fever needing reintervention. § χ2 test, except ¶ Fisher’s exact test and # Mann–Whitney U test.
