Cancers, Vol. 16, Pages 1441: Pathological Insights: Enhanced Vision Transformers for the Early Detection of Colorectal Cancer
Choe
Endoscopic pathological findings of the gastrointestinal tract are crucial for the early diagnosis of colorectal cancer (CRC). Previous deep learning works, aimed at improving CRC detection performance and reducing subjective analysis errors, are limited to polyp segmentation. Pathological findings were not considered and only convolutional neural networks (CNNs), which are not able to handle global image feature information, were utilized. This work introduces a novel vision transformer (ViT)-based approach for early CRC detection. The core components of the proposed approach are ViTCol, a boosted vision transfo...

Cascade-EC Network: Recognition of Gastrointestinal Multiple Lesions Based on EfficientNet and CA_stm_Retinanet
AbstractCapsule endoscopy (CE) is non-invasive and painless during gastrointestinal examination. However, capsule endoscopy can increase the workload of image reviewing for clinicians, making it prone to missed and misdiagnosed diagnoses. Current researches primarily concentrated on binary classifiers, multiple classifiers targeting fewer than four abnormality types and detectors within a specific segment of the digestive tract, and segmenters for a single type of anomaly. Due to intra-class variations, the task of creating a unified scheme for detecting multiple gastrointestinal diseases is particularly challenging. A cas...

Standardised training for endoscopic mucosal resection of large non-pedunculated colorectal polyps to reduce recurrence (*STAR-LNPCP study): a multicentre cluster randomised trial
Conclusion
A compact standardised EMR training for LNPCPs significantly reduced recurrences in community hospitals. This strongly argues for a national dedicated training programme for endoscopists performing EMR of ≥20 mm LNPCPs. Interestingly, in sensitivity analysis, this benefit was limited for LNPCPs ≥40 mm.

Association between endoscopist adenoma detection rate and serrated polyp detection: Retrospective analysis of over 200,000 screening colonoscopies
Conclusions This study shows that endoscopists with higher ADR detect significantly more serrated lesions than those with a lower ADR.

Sessile serrated polyp detection rates after fecal immunochemical test or multitarget stool DNA test: Systematic review and meta-analysis
Conclusions FIT-DNA outperformed FIT in both SSP and ASP detection including FIT with a lower threshold cutoff of >10 ug/g. Further comparative studies are needed to assess the impact of our findings on colorectal cancer reduction.

A rare case of Gardner syndrome in an African adult male: A case report
Key Clinical MessageGardner's syndrome with the complete manifestation of colonic and extracolonic features is uncommon. Therefore, every clinician should view extracolonic features with a high index of suspicion. This may be key to early diagnosis, definitive management in these patients and importantly, helps prevent malignant transformation of existing colonic polyps. (Source: Clinical Case Reports)

Prevalence and predictive factors of colorectal sessile serrated lesions in younger individuals
Conclusion SSLs are not uncommon among younger individuals. Moreover, diligent effort and expertise are of paramount importance in SSL detection. Future studies should explore the clinical significance of SSLs in individuals of younger age.

Cirrhosis and Portal Hypertension Worsen Bowel Preparation for Screening Colonoscopy
CONCLUSIONS: Patients with cirrhosis have worse BBPS scores and longer cecal intubation times. Nonobese cirrhotic patients additionally have a lower polyp detection rate. Portal hypertension complications were associated with worsened preparation quality and longer cecal intubation times. Each incremental increase in MELD score lengthened cecal intubation time. These findings support a more aggressive bowel preparation strategy for patients with cirrhosis, especially patients with severe disease or portal hypertension complications.PMID:38567898 | DOI:10.1097/MCG.0000000000001990 (Source: Clinical Colorectal Cancer)

Multitarget Stool RNA Testing —Reply
In Reply We appreciate the Letters from Drs Imperiale and Baird and colleagues. Regarding sessile serrated lesions (SSLs) of at least 1cm in size, we are following the most recent US Multi-Society Task Force guidelines, which were cited by Imperiale and colleagues. These guidelines state “Because evidence of the risk of metachronous neoplasia associated with serrated lesions is evolving, whenever possible we have chosen not to include SSPs [sessile serrated polyps] and HPs [hyperplastic polyps] in our definitions of low-risk adenoma, high risk adenoma, and advanced neoplasia, and will refer to these lesions separately.â€...
