Which term best describes the technique of creating an opening between two hollow organs?

The term "anastomosis" refers specifically to the surgical technique that creates a connection or opening between two hollow organs. This can involve connecting segments of intestines, blood vessels, or other tubular structures within the body. Anastomosis is often performed to restore continuity after a section of an organ has been removed or to create a new pathway for fluids or other substances to flow between two areas.

This technique is crucial in various surgical procedures, such as bowel surgery, where segments of the intestine might be reconnected after a disease or obstruction has been addressed. It allows for the preservation of function in the affected organ, and the resulting connection can be either temporary or permanent, depending on the situation.

In contrast, an incision refers to a cut made into the body, usually to access an area for surgical intervention. Resection is the removal of a portion of an organ, and excision is the act of cutting out or removing tissue. While these terms are related to surgery, they describe different concepts than the creation of a connection between organs. Thus, anastomosis is the most accurate term for this specific technique.
