Lasers,dependent on their wavelength,can produce absorption,reflection,transmission,and scatter.The effect of laser wavelength scatter does not have any therapeutic benefit at this time and can be destructive to both staff and instruments.Select a safety measure that would prevent inadvertent scatter or heating of the endoscope channel from laser energy during a surgical procedure.
A) Ebonize the surface of laser mirrors that are used in laparoscopic cholecystectomies.
B) Surround the surface drapes and endoscope trocar with moist sterile towels and cover the glass windows.
C) Advance the laser fiber at least 1 cm beyond the tip of the endoscope within operator's view.
D) Cover the laser fiber with medical-grade tubing along its entire length.

Special precautions should be followed when using the laser during an endoscopic procedure.When a laser fiber is introduced through the biopsy port of a flexible or rigid endoscope,the operator must view at least 1 cm of the tip of the fiber before activating the laser.If the end of the fiber is still within the sheath of the endoscope,and the laser is fired,the heat from the laser energy quickly damages the optics and channel of the endoscope.
