Limitations of study
partial obstruction
There were some limitations in our study. First, only the qSOFA score was used in this paper, and the SOFA criteria were not used for further diagnosis. Second, emergency drainage was performed in some patients within 24 h after admission. Early drainage may not be necessary in some patients and may be over-treatment for patients with a partial obstruction or whose obstruction can be controlled using empiric antibiotic therapy. Finally, this was a single-centre study, and the sample size was still relatively small. A large-scale multi-centre analysis with a larger sample size is required to confirm our conclusions.
