Safety and efficacy of Kaffes intraductal self-expanding metal stents in the management of post-liver transplant anastomotic strictures

Table 6 Stent efficacy (stent courses where Kaffes stent was the final stent)

Stricture outcomes	≤ 120 d	> 120 d	P value
n	7	50
Median duration of stent course, d (IQR, d)	95 (90-116)	193 (178-281)
Stricture resolution at end of course, n (%)	7 (100.0)	50 (100.0)	1.00
Recurrence
n (%)	5 (71.4)	9 (18.0)	0.02a
Median days to recurrence (IQR)	248 (104-812)	431 (264-1522)	0.24

^aStricture recurrence was significantly less in stent courses where Kaffes stent was the final stent and left indwelling for >120 d.
