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

Table 7 Stent efficacy (stent courses where Kaffes stent was the only stent used)

Stricture outcomes	≤ 120 d	> 120 d	P value
n	7	21
Median duration of stent course, d (IQR, d)	95 (90-116)	183 (167-193)
Stricture resolution on Kaffes removal, n (%)	7 (100.0)	20 (95.0)	1.00
Recurrence
n (%)	5 (71.0)	2 (10.0)	0.01a
Median days to recurrence (IQR)	248 (27-812)	1139 (785-1493)	0.19

^aStricture recurrence was significantly less when Kaffes stent was used upfront and left indwelling for >120 days.
