¹Multiple symptoms may coexist in one patient, so we didn't calculate percentages of each item.

²Here, we excluded patients that preintervention was inconsistent with original treatment in our hospital.

ETGF: Endoscopic transgastric fenestration; PCD: Percutaneous drainage.

¹There were 8 patients who received a twice percutaneous drainage (PCD) and another 3 required no less than three times of PCD, 2 transferred to endoscopic transgastric fenestration and 7 to surgery after PCD failure. ETGF: Endoscopic transgastric fenestration; PCD: Percutaneous drainage.
