Background: The aim of this study was to establish the feasibility and safety of the use of indocyanine green technology during pediatric intestinal resections. While indocyanine green fluorescence angiography (ICG-FA) has been advocated as an imaging technique to assess bowel perfusion in adults, few studies have evaluated this technology in a pediatric context.
Methods: A prospective clinical trial was conducted. Patients 16 years old or younger undergoing a surgery potentially requiring an intestinal resection were eligible. Patients received a standardized intravenous injection of indocyanine green and intestinal perfusion was evaluated. The study endpoints included safety, impact on bowel resection and feasibility and acceptance of ICG-FA in this population.
Results: From May 2020 to March 2021, 30 consecutive patients were included in this trial. Final analysis was done on 28 patients with a median age of 15.00 [6.36,85.00] weeks and weight of 5.58 [3.64,11.70] kg at surgery. Adequate fluorescence was achieved in less than one minute for all cases with an average dose of 0.14 mg/kg. No adverse event related to indocyanine green occurred. ICG-FA versus standard assessment of potential resection sites differed in 62% (95% IC 0.41-0.82) of our cases. Qualitative analysis demonstrated that 95% of the surgical team agreed that ICG-FA was safe.
Conclusions: The use of ICG-FA is feasible and safe for pediatric intestinal resections. Introduction of ICG-FA was simple and acceptance rates were high within the surgical team. This fluorescence imaging may be a valuable imaging technology for intestinal resections in pediatric surgery.

Boron (B) neutron capture therapy (BNCT) is a novel non-invasive targeted cancer therapy based on the nuclear capture reaction B (n, alpha) Li that enables the death of cancer cells without damaging neighboring normal cells. However, the development of clinically approved boron drugs remains challenging. We have previously reported on self-forming nanoparticles for drug delivery consisting of a biodegradable polymer, namely, "AB-type" Lactosome nanoparticles (AB-Lac particles)- highly loaded with hydrophobic B compounds, namely -Carborane (Carb) or 1,2-dihexyl--Carborane (diC6-Carb), and the latter (diC6-Carb) especially showed the "molecular glue" effect.

Bronchial atresia (BA) and azygos lobe (AL) are rare congenital pulmonary abnormalities in pediatric patients. We herein report an infantile case of BA combined with AL that was treated with thoracoscopic surgery. The patient was an 8-month-old boy who was preoperatively diagnosed with BA of the right upper lobe (RUL) combined with an AL using fetal magnetic resonance imaging and postnatal enhanced computed tomography.

Birdshot chorioretinopathy (BSCR) is a bilateral, chronic posterior uveitis with characteristic clinical and imaging findings. Multimodal imaging including optical coherence tomography, fluorescein, and indocyanine green angiography is useful in diagnosis, as well as monitoring disease activity. Cystoid macular edema, choroidal thickening and infiltration, ellipsoid loss, and vasculitis are important imaging markers for disease activity.

Achalasia cardia is a primary motility disorder of the esophagus marked by the absence of peristalsis and the failure of the lower esophageal sphincter (LES) to relax during swallowing. The preferred surgical approach is laparoscopic Heller's cardiomyotomy with Dor's fundoplication. Given the significant risks of mucosal perforation and the possibility of incomplete myotomy, which can lead to symptom recurrence, it is essential to ensure both the completeness of the myotomy and the preservation of the mucosal integrity.

Purpose: Assessment of tissue perfusion using near-infrared fluorescence (NIR) with indocyanine green (ICG) is gaining popularity, however reliable and objective interpretation remains a challenge. Therefore, this study aimed to establish reference curves for vital tissue perfusion across target tissues using this imaging modality.
Methods: Data from five prospective study cohorts conducted in three Dutch academic medical centres between December 2018 and June 2023 was included.
