Cost savings in colonoscopy with artificial intelligence –aided polyp diagnosis: an add-on analysis of a clinical trial (with video)

Artificial intelligence (AI) is being implemented into colonoscopy practice, but no study has investigated whether AI is cost-saving. We quantified the cost reduction from using AI as an aid in the optical diagnosis of colorectal polyps.

Endosc Int Open 2020; 08: E775-E782 DOI: 10.1055/a-1136-9971 Background and study aims Adenoma detection rate (ADR) is an important quality indicator in colonoscopy, and improved ADR decreases the incidence of colorectal cancer. We investigated differences in polyp detection according to the endoscopist’s ADR. Patients and methods We performed a propensity-score matching study using baseline patient characteristics of age, sex, body mass index, family history of colorectal cancer, smoking, drinking, indication for colonoscopy, bowel preparation, and colonoscope type. We compared polyp detection and co...

This article reviews alternative colorectal cancer (CRC) screening tests, including flexible sigmoidoscopy (FS), computed tomography (CT) colonography, and colon capsule endoscopy. FS has abundant and convincing evidence supporting its use for CRC screening and is a commonly used CRC test worldwide. CT colonography has demonstrated convincing results for CRC screening, but concerns regarding cost, accuracy for flat or sessile neoplasia, reproducibility, extracolonic findings, and lack of coverage have limited its use and development. Colon capsule endoscopy has demonstrated encouraging results for polyp detection in averag...

Serrated polyposis syndrome (SPS) is common, yet under-recognized and is associated with an increased risk of colorectal cancer (CRC). The diagnosis is based on the World Health Organization (WHO) criteria and is inclusive of the cumulative number of lifetime serrated polyps. We used natural language processing (NLP) to extract colonoscopy and pathology data from the electronic medical record (EMR). The aim of this study was to assess feasibility of using an NLP-based SPS tool to identify patients with SPS.

Authors: Shen X, Zhang Y, Zhao Y, Li X, Ge Z, Xiong H, Sun D, Gao Q, Cui Y, Chen X, Chen Y, Fang J Abstract Background: The coexistence of colorectal polyps with laterally spreading tumors (LSTs) is commonly observed during colonoscopy. However, there are rare studies that assess the malignant risks for LSTs with colorectal polyps, which might largely contribute to further strategies of treatment and follow-up plans in LSTs. Methods: We conducted a retrospective cohort study that enrolled 206 patients with LSTs in the Endoscopy Center and Endoscopy Research Institute, Renji Hospital, Shanghai Jiao Tong Universi...

Conclusions In a homogeneous FIT-positive population, no correlation between the ADR, PSPDR, and the sensitivity of optical diagnosis for adenomas and serrated polyps could be demonstrated. These exploratory results suggest that lesion detection and differentiation require different endoscopic skills. Further prospective studies are needed; until then, monitoring of both performance indicators is important to secure optimal efficacy of FIT-based colorectal cancer screening.

Because data on metachronous risk for patients with index proximal 5 to 9 mm hyperplastic polyps (HPs) are limited, the clinical significance of these polyps is unclear. Conversely, published data suggest that sessile serrated polyps (SSPs), traditional serrated adenomas (TSAs) and large (>1 cm) hyperplastic polyps (HPs) are high-risk lesions requiring close surveillance. We used data from the New Hampshire Colonoscopy Registry (NHCR) to examine the risk of metachronous large serrated polyps (SPs) and advanced adenomas in patients with 5 to 9 mm proximal HPs.

Artificial intelligence may improve value in colonoscopy-based colorectal screening and surveillance by improving quality and decreasing unnecessary costs. The quality of screening and surveillance as measured by adenoma detection rates can be improved through real-time computer-assisted detection of polyps. Unnecessary costs can be decreased with optical biopsies to identify low-risk polyps using computer-assisted diagnosis that can undergo the resect-and-discard or diagnose-and-leave strategy. Key challenges include the clinical integration of artificial intelligence-based technology into the endoscopists ’ workflo...

Purpose: The aim of the present study was to evaluate the association of diverticulosis with colorectal polyps, advanced neoplastic lesions (ANLs), and colorectal cancers (CRCs). Methods: The first-time colonoscopy records of 3496 patients were evaluated in this retrospective, cross-sectional cohort study. Data on clinical indications, presence of diverticulosis and diverticulitis, location of diverticula and polps, the size and number of polyps, and results of histopathologic examinations of polypectomies were noted. Categorical data were analyzed with χ2 test or the Fisher exact probability. P-values

Colorectal polyps such as adenomas and serrated polyps are precursors for colorectal cancer (CRC). Therefore, removal of such polyps reduces CRC risk.1 Patients who had adenomas or serrated polyps removed at colonoscopy are believed to be at increased risk of developing more polyps later in life and eventually CRC.2,3 Thus, colonoscopy surveillance after polyp removal is currently recommended.4
