GI Genius Automatically Identifies Possible Polyps During Colonoscopy
At the UEG (United European Gastroenterology) Week event in Barcelona, Spain, the first automatic polyp assistance system was unveiled by Medtronic. The GI Genius intelligent endoscopy system monitors the live video feed from a colonoscope, outli...
Conclusions Using a relatively small set of publicly-available colonoscopy data, we obtained sizable training and validation sets of endoscopic images using data augmentation, and achieved an excellent performance in adenomatous polyp detection.

Fluorescence molecular endoscopy (FME) is an emerging technique that has the potential to improve the 22% colorectal polyp detection miss-rate. We determined the optimal dose-to-imaging interval and safety of FME using EMI-137, a c-Met–targeted fluorescent peptide, in a population at high risk for colorectal cancer. Methods: We performed in vivo FME and quantification of fluorescence by multidiameter single-fiber reflectance/single-fiber fluorescence spectroscopy in 15 patients with a dysplastic colorectal adenoma. EMI-137 was intravenously administered (0.13 mg/kg) at a 1-, 2- or 3-h dose-to-imaging interval (n = 3 ...
We read with interest the article by Turse et al.1 The authors report, in a retrospective study, that deep sedation (DS) had no benefit compared with moderate sedation (MS) for adenoma detection rate (ADR) and polyp detection rate (PDR) in average-risk patients undergoing screening colonoscopy for colorectal cancer. The study populations were similar for both groups, including relatively healthy patients. A highlighted strength of the study was that the focus on average-risk patients examined at the same center minimized possible confounding factors of prior investigations.
Conclusion Incomplete polyp resection was frequent after polypectomy in routine clinical practice. Serrated histology and proximal location were independent risk factors for incomplete resection. The performance of board-certified gastroenterologists was not superior to that of trainees.

Conclusions: Endoo allows smoother navigation than CC and possesses comparable features. Although further research is needed, magnetic capsule colonoscopy demonstrated promising results compared to CC.
Conclusion CCE had high sensitivity and specificity for per-patient polyps compared with standard colonoscopy However, the relatively high rate of incomplete investigations limits the application of CCE in a CRC screening setting.

Conclusion As previously demonstrated for hospital patients, screening participants classified as intermediate risk comprised two risk subgroups. Surveillance clearly benefited the higher-risk subgroup. [...] © Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals: Table of contents | Abstract | open access Full text
Conclusions In an organized screening program, post-colonoscopy adverse events were rare but not negligible. The most frequent event was post-polypectomy bleeding, especially after resection of large (≥ 20 mm) and proximal lesions.

One fourth of colorectal neoplasia is missed at screening colonoscopy, representing the main cause of interval colorectal cancer (CRC). Deep learning systems with real-time computer-aided polyp detection (CADe) showed high accuracy in artificial settings, and preliminary randomized clinical trials (RCT) reported favourable outcomes in clinical setting. Aim of this meta-analysis was to summarise available RCTs on the performance of CADe systems in colorectal neoplasia detection.
Authors: Hausmann J, Tal A, Gomer A, Philipper M, Moog G, Hohn H, Hesselbarth N, Plass H, Albert J, Finkelmeier F Abstract Background/Aims: Reliable and especially widely accepted preventive measures are crucial to further reduce the incidence of colorectal cancer (CRC). Colon capsule endoscopy (CCE) might increase the screening numbers among patients unable or unwilling to undergo conventional colonoscopy. This registry trial aimed to document and determine the CCE indications, findings, complications, and adverse events in outpatient practices and clinics throughout Germany. Methods: Patients undergoing CCE b...
