TABLE 1.

Comparison of risk factors for postendoscopic retrograde cholangiopancreatography pancreatitis (PEP) between patients with moderate or severe PEP

Risk factor	PEP		P
	Moderate (n=59)	Severe (n=27)
Sex, female	47 (79.7)	25 (92.6)	0.209*
Sphincter of Oddi manometry performed	56 (94.9)	24 (88.9)	0.373*
Pancreatic sphincter of Oddi dysfunction	35 (59.3)	16 (59.3)	0.892†
Balloon dilation	5 (8.5)	4 (14.8)	0.453*
No sphincterotomy	3 (5.1)	3 (11.1)	0.439†
One sphincterotomy	16 (27.1)	9 (33.3)
Dual sphincterotomy	40 (67.8)	15 (55.6)
Pancreatography including filling of the tail¶	47/58 (81)	24/27 (88.9)	0.533*
No chronic pancreatitis¶	42/58 (72.4)	24/27 (88.9)	0.156‡
Normal cholangiogram**	43/55 (78.2)	21/26 (80.8)	1.000‡
Risk factors, n (mean)	6.29	6.56	0.380§

Data presented as n (%) or n/n (%) unless otherwise indicated.

^*Fisher’s exact test;

^†χ² test;

^‡Continuity correction;

^§t test;

^¶One patient with moderate pancreatitis was excluded from the denominator because no pancreatogram or report describing the pancreatogram was available for review; however, the pancreatogram performed before this endoscopic retrograde cholangiopancreatography was normal;

^**Three patients with moderate and one patient with severe pancreatitis were excluded from the denominator because a cholangiogram was not performed
