Randomized controlled trial of pancreatic stenting to prevent pancreatitis after endoscopic retrograde cholangiopancreatography

Table 4 Overall post-endoscopic retrograde cholangiopancreatography pancreatitis in non-stent and stent groups

	Non-stent	Stent	P value
No. of patients	60	60
Hyperamylasemia	23 (38.3%)	18 (30%)	0.862
Average serum amylase level (IU/L) (range)	842.4 (381-2040)	746.2 (420-1620)	0.798
Post-ERCP pancreatitis	8 (13.3%)	1 (1.7%)	0.0322
Mild	8	1	0.0322
Moderate	0	0	-
Severe	0	0	-
Average serum amylase level in pancreatitis cases (IU/L) (range)	1720 (820-2040)	1240 (746-1964)	0.04

ERCP: Endoscopic retrograde cholangiopancreatography. The Chi-square test or Fisher’s exact test was used to determine the significance of associations, and P < 0.05 was regarded as significant.
