Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Objective The purpose of this study was to retrospectively analyze the outcomes of the combination of ultrasound-guided percutaneous external drainage (US-PED) and subsequent definitive operation to manage complicated choledochal cyst in children. Methods This study included 6 children with choledochal cyst who underwent initial US-PED and subsequent cyst excision with Roux-en-Y hepaticojejunostomy between January 2021 and September 2022. Patient characteristics, laboratory findings, imaging data, treatment details, and postoperative outcomes were evaluated. Results Mean age at presentation was 2.7 ± 2.2 (0.5–6.2) years, and 2 patients (2/6) were boys. Four patients (4/6) had a giant choledochal cyst with the widest diameter of ≥ 10 cm and underwent ultrasound-guided percutaneous biliary drainage on admission or after conservative treatments. The other 2 patients (2/6) underwent ultrasound-guided percutaneous transhepatic cholangial drainage and percutaneous transhepatic gallbladder drainage due to coagulopathy, respectively. Five patients (5/6) recovered well after US-PED and underwent the definitive operation, whereas 1 patient (1/6) had liver fibrosis confirmed by Fibroscan and ultimately underwent liver transplantation 2 months after US-PED. The mean time from US-PED to the definitive operation was 12 ± 9 (3–21) days. The average length of hospital stay was 24 ± 9 (16–31) days. No related complications of US-PED occurred during hospitalization. At 10.2 ± 6.8 (1.0–18.0) months follow-up, all patients had a normal liver function and US examination. Conclusions US-PED is technically feasible for choledochal cyst with giant cysts or coagulopathy in children, which can provide suitable conditions for subsequent definitive operation with a good overall prognosis.
