Endoscopic therapy for biliary strictures complicating living donor liver transplantation: Factors predicting better outcome

Table 2 Impact of endotherapy protocol and morphology of the stricture on therapeutic efficacy

Endotherapy details	Total (n = 41)	Complete response (n = 20)	Partial/no response (n = 21)

Mean duration of stentinga (mo)	23 (39)	16 (69.5)	7 (23.3)
Morphology of the stricture	5.75	16.4	6.8
Mean length of stricture (mm)	84	82	85

^aP value < 0.05;

^bAggressive stent therapy involves sphincterotomy, serial dilatation of stricture and increase in number/size of stents. LT: Liver transplantation; ERC: Endoscopic retrograde cholangiography.
