Time Periods	Liters (SD)	Liters (SD)	P-value
Periprocedural (arrival to ERCP completion)	0.94 (0.27)	0.81 (0.36)	0.0308

12h – 24h after PEP diagnosis	1.02 (0.65)	1.48 (0.80)	0.0014
24h – 48h after PEP diagnosis	1.16 (1.20)	2.70 (1.40)	<0.0001
Total fluid after PEP diagnosis	3.30 (1.91)	5.50 (2.54)	<0.0001

Before PEP diagnosis fluid volumes were greater in patients with mild PEP compared to those with moderate-severe PEP, particularly during the periprocedural period. In contrast, fluid volumes after PEP diagnosis were smaller in mild PEP compared to moderate-severe PEP, presumably reflecting appropriate treatment decisions related to fluid hydration.
