Operative procedures according to tumor staging (UICC 2002 classification).

T-State	Liver Resection (liver infiltration)	Dissection of Hepatico-Duodenal Ligament (lymph node infiltration)	Biopsy coeliac trunc nodes (lymph node infiltration)	CBD resection/R0 cysticus (CHDB infiltration)	Metastases
T1b n = 1	1/1 (0%)	1/1 (0%)			0%
T2 n = 17	11/17 (0%)	13/17 (25%)	5/17 (0%)	4/17 (25%)	0%
T3 n = 14	7/14 (100%)	7/14 (67%)	2/14 (50%)	5/14 (40%)	liver n = 1 peritoneal carcinosis n = 3
T4 n = 17	6/17 (100%)	4/17 (100%)	2/17 (100%)	0/17	liver n = 5, pancreas n = 1, lung n = 1, peritoneal carcinosis n = 6
Tx n = 4	0/4	0/4		0/4	liver n = 1, peritoneal carcinosis n = 2

Reported is first the number of patients who received the certain procedure and than the total number of patients with the certain tumor stage. In parentheses the percentage of histological proved tumor infiltration in the resection specimens is demonstrated.
