Table 2 Surgical treatment of left hepatic duct stricture and the subsequent re-stricture rates (¯x ± s)

Operative procedures	Cases(%)	Mean follow up period (y)	Re-strictures (%)
Plastic operation plus
Biliary enteric anastomosis	35 (52.2)	9.8 ± 2.7	6 (17.1)f
Severe degree	21 (51.2)	10.6 ± 2.3	4 (19.0)
Mild degree	14 (53.8)	8.6 ± 3.2	2 (14.3)
Left lobectomy	13 (19.4)	9.7 ± 3.0	0 (0.0)e
Severe degree	7 (17.1)	9.1 ± 3.1	0 (0.0)
Mild degree	6 (23.1)	10.3 ± 2.8	0 (0.0)
Stricture repair	6 (9.0)	8.5 ± 3.2	3 (50.0)
Severe degree	4 (9.8)	8.2 ± 3.5	2 (50.0)
Mild degree	2 (7.7)	7.8 ± 10.1	2 (100.0)
Stricture dilation	13 (19.4)	9.9 ± 2.2	12 (92.3)
Severe degree	9 (22.0)	10.7 ± 2.7	9 (100.0)
Mild degree	4 (15.4)	8.1 ± 2.4	3 (75.0)

^fχ² = 19.76, P < 0.01;

^eχ² = 4.69, P < 0.05, vs stricture dilation. No significant difference between severe degree and mild degree.
