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.
