Colony

From Thikipedia

A Colony is the name given to an endoscopic examination of the large colon and the distal part of the small bowel with a CCD camera or a fiber optic camera on a flexible tube passed through the anus, or by eye using amyl nitrite and surgical retractors through the same orifice. These procedures are generally performed in a hospital.

[edit] Preparation

The colon must be free of solid matter for the test to be performed properly. For one to three days, the patient is required to follow a low fibre or clear-fluid only diet. In most cases black coffee is allowed. The day before the colony, the patient is either given a laxative preparation and large quantities of fluid or whole bowel irrigation is performed using a solution of polyethylene glycol and electrolytes.

Since the goal of the preparation is to clear the colon of solid matter, the patient should plan to spend the day at home in comfortable surroundings with ready access to toilet facilities. The patient may also want to have at hand moist toilettes or a bidet for cleaning the anus. A soothing salve such as petroleum jelly applied after cleaning the anus will improve patient comfort.

[edit] History

One of the earliest historical examples of Colony was the Roanoke Colony on Roanoke Island in Dare County in present-day North Carolina. It was an enterprise financed and organized by Sir Walter Raleigh in the late 16th century. Between 1585 and 1587, groups of colonists experimented at Roanoke, all of whom either abandoned the colony or disappeared. The final group disappeared after a period of three years elapsed without supplies (rubber tubes, lubricants, etc.) from England, leading to the continuing mystery known as "The Lost Colony."
