| Abstract |
Video-assisted thoracic surgery (VATS) pulmonary resection in children is a technically demanding procedure that requires a relatively long learning period. This study aimed to evaluate the serial improvement of quality metrics according to case volume experience in pediatric VATS pulmonary resection of congenital lung malformation (CLM). Methods VATS anatomical resection in CLM was attempted in 200 consecutive patients. The learning curve for the operative time was modeled by cumulative sum analysis. Quality metrics were used to measure technical achievement and efficiency outcomes. Results The median operative time was 95 min. The median length of hospital stay and chest tube indwelling time was 4 and 2 days, respectively. The improvement of operation time was observed persistently until 200 cases. However, two cut-off points, the 50th case and 110th case, were identified in the learning curve for operative time, and the 110th case was the turning point for stable outcomes with short operation time. Significant reduction of length of hospital stay and chest tube indwelling time was observed after 50 cases (p = .002 and p = .021, respectively). The complication rate decreased but continued at a low rate for entire study period and the interval decrease was not statistically significant. Conversion rate decreased significantly (p = .001), and technically challenging procedures were performed more frequently in later cases. Conclusions Improvements of quality metrics in operation time, conversion rate, length of hospital stay, and chest tube indwelling time were observed in proportion to case volume. Minimum experience of 50 is necessary for stable outcomes of pediatric VATS pulmonary resection. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 16 February 2017.
All research outputs
#18,531,724
of 22,953,506 outputs
Outputs from Surgical Endoscopy
#4,789
of 6,087 outputs
Outputs of similar age
#335,771
of 454,358 outputs
Outputs of similar age from Surgical Endoscopy
#67
of 85 outputs
Altmetric has tracked 22,953,506 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,087 research outputs from this source. They receive a mean Attention Score of 4.1. This one is in the 6th percentile – i.e., 6% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 454,358 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 15th percentile – i.e., 15% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 85 others from the same source and published within six weeks on either side of this one. This one is in the 3rd percentile – i.e., 3% of its contemporaries scored the same or lower than it.
