Fifty-five cases of hepatic alveolar echinococcosis combined with lymph node metastasis: A retrospective study

Table 2 Comparative analysis of lymph node metastasis sites in 55 cases

Sites	Para-hepatoduodenal ligament lymph nodes	Posterior pancreatic head lymph nodes	Para-common hepatic artery lymph nodes	Para-aorta abdominalis lymph nodes	Para-diaphragmatic lymph nodes	Celiac trunk lymph nodes
Number of metastasis cases	39a	9b	4b	5b	2b	1b
Number of non-metastasis cases	16a	46b	51b	50b	53b	54b
Metastasis rate (%)	70.9	16.4	7.3	9.1	3.6	1.8
χ2	128.089a
P value	0

^aP < 0.05, para-hepatoduodenal ligament lymph nodes vs other five groups (posterior pancreatic head lymph nodes, para-common hepatic artery lymph nodes, para-aorta abdominalis lymph nodes, para-diaphragmatic lymph nodes, and celiac trunk lymph nodes) respectively.

^bP > 0.05, compared with posterior pancreatic head lymph nodes, para-common hepatic artery lymph nodes, para-aorta abdominalis lymph nodes, para-diaphragmatic lymph nodes, and celiac trunk lymph nodes.
