Parameters That May Be Used for Predicting Failure during Endoscopic Retrograde Cholangiopancreatography

Table 4

Distribution of cannulation success rates for each endoscopists in cases where a second ERCP was performed after a failed first ERCP (chi-square test, 𝑃=0.428).

Endoscopist	Cannulation		Total
	No	Yes
Endoscopist 1	33 (35.5%)	60 (64.5%)	93 (100%)
Endoscopist 2	9 (23.7%)	29 (76.3%)	38 (100%)
Endoscopist 3	10 (27.8%)	26 (72.2%)	36 (100%)
Endoscopist 4	7 (23.3%)	23 (76.7%)	30 (100%)
Total	59 (29.9%)	138 (70.1%)	197 (100%)
