The analysis of volatile organic compounds (VOCs) in feces is a promising approach to gastrointestinal disease detection. In this investigation, an electronic nose (or “e-nose”) was used for fecal gas analysis of stool samples collected from healthy controls and patients with colorectal carcinoma or advanced adenoma. VOC profiles for colorectal carcinoma and advanced adenoma were found to differ significantly from control profiles. The opportunity for scalability for high-throughput capacity makes e-nose fecal gas analysis especially appealing as a possible screening tool for the detection of colorectal malignancies.
