Abstract
The aim was to develop a new diagnostic tool for reservoir and evacuatory rectal functions assessment without radiation exposure and to collect normative values. Materials and methods. Literature search was performed to collect data on the limitations of the existing methods of rectal function assessment. Based on the results, we identified requirements for a new diagnostic technique development to avoid limitations of the existing methods. We developed new optical weight sensor and modified defecoflowmetry technique to make possible simultaneous evaluation of rectal reservoir and evacuatory functions. Safety and efficacy of the method were assessed based on the examination of 19 healthy volunteers, who gave informed consent to participate in the study. Results: Optical weight sensor used with defecoflowmetry allows parallel assessment of evacuation and reservoir functions of the rectum in qualitative and quantitative measures without exposure to X-ray. Preliminary results obtained in 19 healthy volunteers shows that the method is safe, well-tolerated and objective. Conclusions: the developed modified DFM technique with the original optical weight sensor is a new way to assess the functional state of the anorectal zone. The technique effectively allows parallel assessment of the evacuation and reservoir functions of the rectum without radiation exposure.
