Laser-assisted removal of a foreign body impacted in the esophagus.

abstract：BACKGROUND AND OBJECTIVE:The clinical application of laser-assisted vascular anastomosis is afflicted by unreliable and low bonding strengths as well as tedious handling during microvascular surgery. The challenge to be met arises from the flow-off of the chromophore during soldering that changes the absorption and sta...
