EUS-GUIDED DRAINAGE OF PERIPANCREATIC FLUID COLLECTIONS USING FULLY COVERED METAL AND PLASTIC STENTS

Aims:

Endoscopic ultrasound (EUS)-guided drainage of peripancreatic fluid collections (PFCs) by using double-pigtail plastic stents (DPPSs) requires placement of multiple stents for favorable outcomes. EUS- guided drainage PFC with fully covered metal stents (FCSEMSs) has become increasingly used. We aim to evaluate the technical, clinical outcomes, and adverse events of EUS-guided drainage of PFC with DPPSs and FCSEMSs.

Methods:

The data of patients who had undergone EUS-guided drainage of PFC with DPPSs and FCSEMSs between January 2005 and December 2017 were retrospectively analyzed. Data of EUS-guided PFC drainage is obtained from prospective collected EUS database of our institute and reviewed of patients's clinical parameters based on electrical medical record.

Results:

133 patients (79 in FCSEMSs group and 54 in DPPSs group) were enrolled in this study. There was no difference in technical success rate between FCSEMSs and DPPSs groups (98.7% vs. 96.3%, P = 0.35). The procedure time was significantly shorter in FCSEMS group than in DPPSs group (FCSEMS vs. DPPSs; 13.7 ± 6.35 vs. 25.5+11.2, P < 0.05). FCSEMSs showed a significantly higher clinical success rate (96.2% vs. 81.5%, P = 0.005). Procedure-related adverse events occurred significantly less in the FCSEMSs group (3.8% vs. 6.7%, P = 0.01). late adverse events also occurred significantly less in the FCSEMSs groups (3.8% in FCSEMSs group vs. 14.8% in DPPSs group, P = 0.02).

Conclusions:

Both EUS-guided drainage of PFC with DPPSs and FCSEMSs might be good methods for drainage. However, EUS-guided drainage of PFC with FCSEMSs might be more likely to achieve clinical success and reduce procedure-related and late adverse events.
