A spectrally and temporally programmable light engine can create any spectral profile for hyperspectral, fluorescence, or principal-component imaging or with medical photonics devices employing spectroscopy, microscopy, and endoscopy. Multispectral imaging feasibility was demonstrated by capturing nine images at wavelengths from 450 to 650 mm (25-nm FWHM) with a CCD-camera-equipped bronchoscope coupled to the light engine. Selected wavelength regions were combined to produce a color endoscopy image.

Precise localization of the fistula is the most important step in the operative strategy for dealing with H-type tracheoesophageal fistula. Bronchoscopic cannulation of the fistula with a Fogarty or ureteric catheter has been recommended to aid ready identification, but it is not always successful. We report an innovative technique that permitted localization of H-type fistula intraoperatively. A flexible pediatric 2.2-mm bronchoscope (Olympus BF Type N20) was steered through a standard endotracheal tube, and the fistula tract was illuminated, making its identification and subsequent repair straightforward. We have successfully deployed this approach in 3 newborns. We recommend the technique to localize H-type fistula.
