Preliminary study of a new pathological evolution-based clinical hepatolithiasis classification

Table 1 Comparison of surgery options in the four types of hepatolithiasis

	Primary	Inflammatory	Mass-forming	Terminal	Total	Percentage
Biliary tract exploration + external T tube drainage	7	4	1	1	13	19.1%
Biliary tract exploration + cholangioenterostomy	0	3	0	0	3	4.4%
Partial liver resection + external T tube drainage	22	8	5	0	35	51.5%
Partial liver resection + cholangioenterostomy	5	10	1	1	17	25.0%
Total	34	25	7	2	68

Table 2 Comparison of immediate and final stone clearance rate in each type of hepatolithiasis n (%)

	Primary	Inflammatory	Mass-forming	Terminal	Total
Immediate case	26 (76.5)	19 (76.0)	4 (57.1)	1 (50.0)	50 (73.5)
Final case	31 (91.2)	23 (92.0)	5 (71.4)	2 (100)	61 (89.7)

Table 3 Comparison of stone clearance rate in liver resection and non-liver resection groups

	Total cases	Clearance cases	Clearance rate	P value
Liver resection	52	40	76.9%	0.332
Non-liver resection	16	10	62.5%
