Proper bile duct flow, rather than radical excision, is the most critical factor determining treatment outcomes of bile duct cysts

Table 2 Late complications and long-term biliary function of patients with Type Ia bile duct cysts

	Complete excision+ proper bile flow (n = 138)	Complete excision only (n = 14)	Partial excision+ proper bile flow (n = 12)	Partial excision only (n = 2)	p-value (function of extent of excision)	P-value (function of proper bile flow)
Late complications	0	12 (85.7)	2 (16.7)	2 (100)	0.012	<.00001
Long-term biliary function					0.012	<.00001
Excellent	130 (94.2)	1 (7.1)	3 (25)	0
Good	8 (5.8)	1 (7.1)	7 (58.3)	0
Fair	0	10 (71.4)	2 (16.7)	0
Poor	0	2 (14.4)	0	2 (100)

Data are expressed as number of cases (percentage)
P-values were calculated based on a chi-square test to compare distributions of late complications and long term biliary function on complete excision and bile flow status
