Table 2 Diagnostic concordance of pathological subtype and grade between endoscopic biopsy specimens and resected specimens (n = 22).
Pathological subtype | ||
|---|---|---|
Endoscopic biopsy specimens | Resected specimens | |
I-type (n = 15) | M&PB-type (n = 7) | |
I-type (n = 13) | 13 | 0 |
M&PB-type (n = 9) | 2 | 7 |
κ = 0.805 (95% CI, 0.55–1.06), P < 0.001 | ||
CI, confidence interval, I-type, intestinal type; M&PB-type, mixed and pancreatobiliary type | ||
Pathological grade | ||
|---|---|---|
Endoscopic biopsy specimens | Resected specimens | |
tub1 (n = 15) | tub2 or por (n = 7) | |
tub1* (n = 18) | 15 | 3 |
