A meta-analysis on the comparison between endoscopic ultrasound-guided drainage and percutaneous drainage for treating pancreatic pseudocyst / 中华胰腺病杂志

ABSTRACT

Objective:To evaluate the efficacy of endoscopic ultrasound-guided drainage (EUS-GD) and percutaneous drainage (PD) for the treatment of pancreatic pseudocyst (PPC) by meta-analysis.Methods:The key words were pancreatic pseudocyst, endoscopic ultrasonography, percutaneous drainage, endoscopic ultrasound-guided, EUS and EUS-guided, and the databases of CNKI, Wanfang, PubMed and Web of science were searched from the establishment to October 1, 2021 for the retrospective cohort studies on PD, endoscopic ultrasonography and PPC. The article were screened and the quality was evaluated according to the pre-set inclusion and exclusion criteria; and important data were extracted. The software REVMAN5.3 was used for meta-analysis.Results:14 articles were finally included, and a total of 843 patients with PPC were enrolled (485 in the EUS-GD group and 358 in the PD group). Mesh meta-analysis showed that in the incidence of technical success rate, clinical success rate and complication rate, there were no significant differences between PD group and EUS-GD group ( OR=0.69, 95% CI 0.32-1.46; OR=1.31, 95% CI 0.88-1.95; OR=1.01, 95% CI 0.70-1.47, all P value >0.05); but the incidence of the recurrence rate and reintervention rate in EUS-GD group were significantly lower than those in the PD group and the differences were statistically significant ( OR=0.45, 95% CI 0.23-0.85; OR=0.51, 95% CI 0.28-0.93, all P value <0.05). Conclusions:Compared with PD, EUS-GD can significantly reduce recurrence rate and complication rate, and it has more advantages than PD for the treatment of PPC.
