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

Table 1 Comparison of the diagnostic compliance rate of 55 cases of hepatic alveolar echinococcosis with lymph node metastasis diagnosed by different imaging methods

Diagnosis method	Number of examined cases (n)	Diagnosis of hepatic AE		Diagnosis of lymph node metastasis
		n	%	n	%
USG	55	55	100	9	16.4
CT	55	55	100	17	30.9
MRI	33	33	100	6	18.2

AE: Alveolar echinococcosis; USG: Ultrasonography; CT: Computed tomography; MRI: Magnetic resonance imaging.

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.
