Comparing the conventional stent replacement technique with the novel puzzle ring technique.

	Conventional technique (n = 68)	Puzzle ring technique (n = 18)	p‐value
Technical success of 7‐F DPS replacement, n (%)	42/68 (61.8)	17/18 (94.4)	0.02
Overall recurrence of pancreatic fluid collection, n (%)	4/68 (5.9)	0/18 (0)	0.29
7‐F DPS replacement success case, n (%)	0/42 (0)	0/17 (0)
7‐F DPS replacement failure case, n (%)	4/26 (15.4)	0/1 (0)

Abbreviation: DPS, double‐pigtail plastic stent.
