ANGIODIN-PROCTO
THE ADL TECHNIQUE
The ADL (Artery Detection & Ligation) technique is the core of the ANGIODIN-Procto System. Organ preserving and effective treatment of hemorrhoidal disease is provided by accurate detection of the artery. Advanced Doppler modes of the ANGIODIN-Procto System are aimed to determine the precise location of the artery as well is its depth. This ensures a minimally invasive, targeted intervention with a small wound surface.
​
The system works with different Doppler modes: Spectral (CW, PW), Color mapping (M, M + PW) and Diagnostic (CW, PW). Combination of the traditional Spectral and the innovative Color mapping modes provides an easy way for precise identification of hemorrhoidal arteries and reliable confirmation of procedure results. The advanced diagnostic mode provides additional facilities for observation of hemorrhoidal arteries over time.
​
In order to determine the position of the artery, the handle is used to rotate the proctoscope clockwise so that the built-in Doppler sensor matches the position of the conditional dial. The display reflects the graphical characteristic of the pulse wave typically for arteries or veins. At that stage the artery could be ligated through the operating window. If the ADL has been successful, the Doppler spectrum becomes considerably less or disappears.
The classical conditional dial layout of hemorrhoidal arteries allowsmarking the position of performed ligations as well as accompanying procedures.
