Abstract
En 中文
Bionic technology is gaining momentum in medical research. In gastroenterology, bionic technologies such as the PillCam and SmartPill assess intestinal mucosa morphology and function during the gastrointestinal passage of the devices. Oral drug delivery devices and intestinal robots are other bionic technologies under development. Recently, Fecobionics, a simulated feces, was developed for assessment of anorectal (defecatory) function. It is an anally insertable device with shape and consistency like feces. The integrated device measures anorectal pressures, orientation, bending (a proxy of the anorectal angle), and the shape of the device when located in rectum and when being evacuated by patients. It integrates most elements of the current technologies on the market (balloon expulsion technology, high-resolution anorectal manometry, defecography, and the functional luminal imaging probe). Multiple measurements in a single study by a bionic device have obvious advantages since novel functional parameters can be computed. Several Fecobionics prototypes have been developed and evaluated in normal human subjects and in patients with fecal incontinence and defecatory disorders such as obstructed defecation. This paper provides an overview of the Fecobionics platform for assessment of defecatory function and dysfunction with a focus on design, signal processing, data analysis, current clinical trials, and future applications in diagnostics, therapy assessment, and therapy.
