As recent as 30 years ago, all surgery was performed in hospitals. While a hospital is ideal for complex cases requiring intensive care units, most surgery is related to minor healthcare problems.

Because a hospital will naturally focus its resources and attention on the complex case, the patient with a simple surgery can be forced to endure long waits for access to an operating room, extensive red tape related to admitting procedures, and have an expensive overnight stay when they could be sleeping more comfortably in their own bed at home.

Physicians have long recognized that simple surgical cases need a separate high quality environment that caters to these specific patients and aims for higher patient satisfaction. Accordingly, in 1970, the first Ambulatory Surgery Center (ASC) opened. Now the trend is for most simple surgeries to be performed in ASCs. Each year, eight million Americans have surgery in an ASC rather than a hospital.

Physicians perform state-of-the-art minimally invasive surgery at High Plains Surgery Center to help patients recover in a shorter period of time and in the comfort of their own home.
