METHOD FOR INTRASURGICAL DIAGNOSTICS OF THE PATHOLOGY OF BILIARY DUCTS AT LAPAROSCOPIC OPERATIONS Russian patent published in 2007 - IPC A61B8/00 

FIELD: medicine, abdominal surgery.

SUBSTANCE: the present innovation should be applied for qualitative diagnostics of the pathology in hepatopancreobiliary area in case of laparoscopic operations upon biliary tracts. Simultaneously, it is necessary to detect the availability of intra-ductal inclusions, evaluate the structure and the function of choledochus' distal departments, measure the diameter of hepaticocholedochus, visualize evacuation into duodenum due to modeling ductal processes being characteristic for low-pressure vessels. Intraoperational laparoscopic ultrasound trial should be carried out in B-mode and in the mode of duplex scanning by energy. Moreover, the trial should be fulfilled during "vascularization" of biliary ducts due to creating there the temporary dosed biliary hypertension ranged 350-500 mm water column and the flow of liquid inside the hepaticocholedochus to be introduced through the catheter towards duodenum. It is necessary to exclude the ductal compression with an ultrasound sensor at measuring the diameter of hepaticocholedochus. As the liquid to be introduced into the ducts one should apply isotonic solution, for example, sodium chloride.

EFFECT: higher accuracy and information value.
