Medical procedure via natural opening

Abstract

The medical procedure via a natural opening according to the present invention includes: adjusting the patient's body so that a target site on the anterior wall of a hollow organ faces in the direction opposite to the direction of gravitational force; introducing a liquid inflow conduit in the vicinity of the target site, and flowing liquid into the hollow organ via the liquid inflow conduit, to form a liquid holding area and a gas retaining area inside the hollow organ; introducing an observation device into the hollow organ, and confirming the position of the target site from the position of the gas retaining area; and incising while observation the target area.
