FIELD: medicine.
SUBSTANCE: method involves measuring specific electric resistance of biological tissue using electrode device to estimate edema degree from specific electric resistance variation pattern. Canal is built before taking measurements in biological tissue to place and fix there an electrode unit. The canal is formed by creating organ wall fold and fixing the edges. The electrode unit has rope composed of four flexible current-conducting wires, each being connected in series to four biologically inert ring-shaped electrodes mounted on the rope. External wires are current-operating wires and internal ones are measuring wires. Distance between current-operating electrodes is 2-4 times as large as examination depth. Distance between measuring electrodes is not greater than 1/3 of the distance separating the current-operating ones.
EFFECT: enhanced effectiveness of monitoring.
