ABSTRACT
BACKGROUND: Fluorescence-guided surgery (FGS) with indocyanine green (ICG) is a rapidly diffusing surgical innovation, but its utilization in pediatrics remains unknown. We present a cross-sectional descriptive analysis of trends from a national database. METHODS: The Pediatric Health Information System (PHIS) database was queried for patient encounters between January 2016 and July 2021 with an associated ICG administration within 3 days prior to surgery. All procedure codes from each encounter were reviewed by two surgeons to determine the most likely associated FGS procedure and assign an operative category. RESULTS: 1270 encounters were identified from 38 participating hospitals. The mean patient age (SD) was 8.3 (6.4) years, 54.5% were male, 63.8% were white, and 30.1% were Hispanic. The most common categories for ICG use were neurosurgery (21.3%), biliary (18.3%), perfusion (14.8%), urology (12.5%), gastrointestinal (10.8%), ophthalmology (8.8%), and thoracic (5.6%). Utilization over time increased for some categories (thoracic, visceral perfusion, and neurological procedures) or remained stable for other categories. Overall ICG utilization has increased in 2020 (n = 314) compared to 2016 (N = 83). The number of centers utilizing ICG has also increased from 14 hospitals in 2016 to 29 hospitals in 2020 though adoption remains unevenly distributed, with 5 high-utilization hospitals accounting for 56.8% of all ICG FGS cases. CONCLUSION: ICG is being used across a wide variety of pediatric surgical disciplines. Trends over time show increasingly frequent adoption across the country, with a few high-volume centers driving the innovation. Fluorescence-guided surgery is commercially available and is becoming more commonplace for pediatric surgeons. Dedicated efforts will now be needed to assess outcomes using this promising technology. LEVEL OF EVIDENCE: Level IV. STUDY TYPE: Retrospective study.

BACKGROUND: Prolonged sitting time has been associated with numerous deleterious effects on humans. The degree to which sitting time influences weight loss outcomes of obesity treatments is poorly understood. OBJECTIVES: The objective was to characterize and describe the amount of time spent sitting in an adolescent bariatric surgical and nonoperative cohort and evaluate its relationship with long-term change in body mass index (BMI). SETTING: Tertiary care hospital, United States. METHODS: From 2011 to 2014, a 1-time study visit was conducted to collect long-term outcomes of Roux-en-Y gastric bypass (RYGB; n = 58) and nonoperative (n = 30) management of adolescents with severe obesity. The International Physical Activity Questionnaire was used to assess sitting time. Linear regression was used to evaluate the association between sitting time and percent BMI change from baseline. RESULTS: A total of 88 patients participated in the long-term follow-up visit at an average of 8 years from baseline. Percent BMI loss for participants who underwent RYGB (mean age at follow-up 25 yr) and for nonoperative (mean age at follow-up 23 yr) participants was -29% and +8%, respectively. The surgical group reported a median sitting time of 5.1 hr/d, while the nonoperative group reported a median sitting time of 7.0 hr/d (P = .11). Increasing sitting time was significantly associated with decreased percent BMI loss (P < .01). CONCLUSIONS: RYGB was associated with long-term weight loss. Those participants with and without prior RYGB self-reported similar amounts of time spent sitting each day. Irrespective of whether participants had previously undergone surgery, lower levels of sitting time were found to be associated with greater BMI loss many years later.
