Median total daily optimised doses were highest after pancreatectomy (240,000 PhU, IQR 175,000\u2013375,000) and in pancreatic cancer (210,000 PhU, 175,000\u2013325,000), compared with chronic pancreatitis (175,000 PhU, 120,000\u2013210,000) and acute pancreatitis (100,000 PhU, 75,000\u2013200,000).
