[Pilot experience with indocyanine green navigation in pediatric surgery].

Introduction: Indocyanine Green (ICG) fluorescence is a new tool for navigated minimal invasive and open surgery, with multiple possible uses, that can increase safety and improve surgical results, facilitating intraoperative decision making. We hereby present our pilot series using ICG navigation in different procedures of pediatric surgery.
Material and Methods: As a proof of concept, between May 2017 and March 2019, we have used this technique as a help for decision making in these scenarios: visualization of the biliary tract, vascular and lymphatic structures, neoplastic tissue and other anatomic landmarks. The route of administration, timing and dosage changed depending on the indication. A 30º optic, with a conventional and near-infrared light emitter, connected to a high definition system specially equipped was used.
Results: We considered that the technique might be useful in 20 patients (22 procedures): 6 involving the biliary tract (5 cholecystectomies, 1 choledochal stenosis), 9 oncologic procedures (5 laparoscopic and 4 open), 7 miscellanea (pulmonary nodule resections, long-gap esophageal atresia, anastomotic leak, etc). There were no complications regarding ICG administration. We considered that the system provided relevant information or affected intraoperative decision making in 90% of the cases.
Conclusions: ICG navigation was easy to perform and complication free. Our preliminary results suggest that ICG navigation, in open and endoscopic procedures, might provide a qualitative leap regarding safety and facilitate the performance of certain pediatric surgical procedures, particularly in oncology, liver surgery and neonatal surgery.
