Een internationaal onderzoek onder leiding van mensen van de Radboud universiteit bij een onderzoek door AI = Kunstmatige Intelligentie van de dikke darm met een camera, levert veertig procent meer opgespoorde darmpoliepen op. Darmpoliepen kunnen als ze kwaadaardig zijn een voorloper zijn van darmkanker.
Uit eerder onderzoek bleek al dat meer opgespoorde en verwijderde darmpoliepen via een endoscopie leidt tot minder darmkanker. Maar nu blijkt ook dat een door AI = Kunstmatige Intelligentie aangestuurd computerprogramma er nog veel meer darmpoliepen worden ontdekt. 

Hier het ongewijzigde persbericht van de Radboud Universiteit en daaronder het originele studierapport uit the Lancet Digital Health.

Een slimme computer die met AI meekijkt bij een onderzoek van de dikke darm met een camera, levert veertig procent meer opgespoorde poliepen op, structuren die een voorloper kunnen zijn van kanker. Dat blijkt uit een publicatie van het Radboudumc in The Lancet Digital Health. Uit eerder onderzoek bleek al dat meer opgespoorde en verwijderde poliepen leidt tot minder darmkanker.

Jaarlijks krijgen in Nederland meer dan 100.000 mensen een kijkonderzoek van de dikke darm, een endoscopie. Daarbij gaat een arts met een camera in de darm op zoek naar darmkanker en poliepen, uitstulpingen van de darmwand, die een voorloper van darmkanker kunnen zijn. Uit eerder onderzoek bleek al: hoe meer poliepen de arts vindt en verwijdert, hoe kleiner de kans dat iemand later darmkanker ontwikkelt.

Nu blijkt dat AI daarbij flink kan helpen. Een arts vindt bijna veertig procent meer poliepen als een slimme computer meekijkt met de camerabeelden in de darm. ‘Een arts kan poliepen missen, omdat die net te kort in beeld zijn, of de aandacht op een andere plek gefocust is’, zegt arts-onderzoeker Michiel Maas. ‘Maar een computer bekijkt iedere pixel in het beeld en is iedere milliseconde even alert. Dat geeft een enorme meerwaarde.’>>>>>>>lees verder

A computer-aided polyp detection system in screening and surveillance colonoscopy: an international, multicentre, randomised, tandem trial

Open AccessPublished:March, 2024DOI:https://doi.org/10.1016/S2589-7500(23)00242-X

Summary

Background

Studies on the effect of computer-aided detection (CAD) in a daily clinical screening and surveillance colonoscopy population practice are scarce. The aim of this study was to evaluate a novel CAD system in a screening and surveillance colonoscopy population.

Methods

This multicentre, randomised, controlled trial was done in ten hospitals in Europe, the USA, and Israel by 31 endoscopists. Patients referred for non-immunochemical faecal occult blood test (iFOBT) screening or surveillance colonoscopy were included. Patients were randomomly assigned to CAD-assisted colonoscopy or conventional colonoscopy; a subset was further randomly assigned to undergo tandem colonoscopy: CAD followed by conventional colonoscopy or conventional colonoscopy followed by CAD. Primary objectives included adenoma per colonoscopy (APC) and adenoma per extraction (APE). Secondary objectives included adenoma miss rate (AMR) in the tandem colonoscopies. The study was registered at ClinicalTrials.govNCT04640792.

Findings

A total of 916 patients were included in the modified intention-to-treat analysis: 449 in the CAD group and 467 in the conventional colonoscopy group. APC was higher with CAD compared with conventional colonoscopy (0·70 vs 0·51, p=0·015; 314 adenomas per 449 colonoscopies vs 238 adenomas per 467 colonoscopies; poisson effect ratio 1·372 [95% CI 1·068–1·769]), while showing non-inferiority of APE compared with conventional colonoscopy (0·59 vs 0·66; p<0·001 for non-inferiority; 314 of 536 extractions vs 238 of 360 extractions). AMR in the 127 (61 with CAD first, 66 with conventional colonoscopy first) patients completing tandem colonoscopy was 19% (11 of 59 detected during the second pass) in the CAD first group and 36% (16 of 45 detected during the second pass) in the conventional colonoscopy first group (p=0·024).

Interpretation

CAD increased adenoma detection in non-iFOBT screening and surveillance colonoscopies and reduced adenoma miss rates compared with conventional colonoscopy, without an increase in the resection of non-adenomatous lesions.
