Which stapler is used to create an anastomosis between two hollow organs end-to-end?

The harmonic scalpel uses which energy source to cut and coagulate tissue?

What is the proper care for a flexible endoscope immediately after use?
Answer: Wipe the insertion tube and suction channels at the bedside, then send for high-level disinfection
