    摘要： This invention concerns a method for automatically detecting a clinically relevant leak and/or inadequate closure following a medical procedure, in a hollow organ (2) residing in the interior volume (4') of a body cavity (4).
    Wherein said test method comprises the steps of:
    injecting, via adapted injection means (3) a specific test gas or a gas mixture containing at least one test gas, into said organ(s) (2),
    analyzing the gas mixture and measuring the concentration of test gas in the interior volume (4') of the body cavity (4) via adapted detection means (5) and at least during a measurement window,
    evaluating the likelihood of the presence of a leak and its degree of severity, by comparing stored data and realtime data with each other,
    said test method being characterized in that the pressure difference between the interior of the hollow organ(s) (2) and the interior volume (4') of the body cavity (4) is controlled or mastered at least at a given moment during at least one measurement window, and preferably maintained constant during said window.
