†
Endoscopic necrosectomy was performed at index procedure in five patients in the plastic cohort and in seven patients in the integrated LAMS cohort.
‡
Multi‐gate technique in the integrated LAMS group were using only LAMS in 15 patients and modified multi‐gate technique (using both LAMS and plastic stents) in eight patients.
§
Nasocystic drains were inserted in 17 patients and percutaneous drains were inserted in seven patients.
IQR, interquartile range; LAMS, lumen‐apposing metal stent; SD, standard deviation.
