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

Table 5 Stent efficacy based on stent course duration (all stent courses involving Kaffes insertion, regardless of Kaffes indwelling time)

Stricture outcomes	≤ 120 d	> 120 d	P value
n	7	56
Median duration of stent course, d (IQR, d)	95 (90-116)	196 (176-296)
Stricture resolution on Kaffes removal, n (%)	7 (100.0)	50 (89.3)	0.66
Recurrence
n (%)	5 (71.4)	12 (21.4)	0.03a
Median days to recurrence (IQR)	248 (104–812)	368 (259-1084)	0.33

^aStricture recurrence was significantly less when Kaffes was inserted for > 120 d.
