Background: Computer-aided diagnosis (CAD) for colonoscopy may help endoscopists distinguish neoplastic polyps (adenomas) requiring resection from nonneoplastic not resection, potentially reducing cost. Objective: To evaluate the performance of real-time CAD with endocytoscopes (×520 ultramagnifying colonoscopes providing microvascular and cellular visualization colorectal after application narrow-band imaging [NBI] methylene blue staining modes, respectively). Design: Single-group,...
The adenoma detection rate is an established quality indicator for colonoscopy. For instance, a 1% increase in the was associated with 3% decrease interval colorectal cancer incidence.1Corley D.A.

Abstract Background and study aims Decisions concerning additional surgery after endoscopic resection of T1 colorectal cancer (CRC) are difficult because preoperative prediction lymph node metastasis (LNM) is problematic. We investigated whether artificial intelligence can predict LNM presence, thus minimizing the need for surgery. Patients methods Data on 690 consecutive patients with CRCs that were surgically resected in 2001 – 2016 retrospectively analyzed. divided into two groups...
Recent advances in endoscopic technology have allowed many T1 colorectal carcinomas to be resected endoscopically with negative margins. However, the criteria for curative resection remain unclear. We aimed identify risk factors nodal metastasis carcinoma patients and hence establish indication additional surgery lymph node dissection.Initial or dissection was performed 653 cases. Clinicopathological were retrospectively analyzed respect metastasis. The status of muscularis mucosae (MM...
Lymph node metastasis (LNM) prediction for T1 colorectal cancer (CRC) is critical determining the need surgery after endoscopic resection because LNM occurs in 10%. We aimed to develop a novel artificial intelligence (AI) system using whole slide images (WSIs) predict LNM.We conducted retrospective single center study. To train and test AI model, we included status-confirmed T2 CRC between April 2001 October 2021. These lesions were divided into two cohorts: training (T1 T2) testing (T1)....
Submucosal invasion depth (SID) in colorectal carcinoma (CRC) is an important factor estimating risk of lymph node metastasis, but can be difficult to measure, leading inadequate or over-extensive treatment. Here, we aimed clarify the practical aspects measuring SID T1 CRC.We investigated 568 CRCs that were resected surgically at our hospital from April 2001 December 2013, and relationships between clinicopathological factors, including means measurement, lesion morphology, metastasis.Of...
Abstract Backgrounds and Aims The Mayo endoscopic subscore [MES] is the most popular disease activity measure of ulcerative colitis [UC]. Artificial intelligence [AI]-assisted colonoscopy expected to reduce diagnostic variability among endoscopists. However, no study has been conducted ascertain whether AI-based MES assignments can help predict clinical relapse, nor AI verified improve performance non-specialists. Methods This open-label, prospective cohort enrolled 110 patients with UC in...
To develop and externally validate an updated artificial intelligence (AI) prediction system for stratifying the risk of lymph node metastasis (LNM) in T2 colorectal cancer (CRC).
Background and Aim Endocytoscopy ( EC ) at ultra‐high magnification enables in vivo visualization of cellular atypia gastrointestinal mucosae. Clear images are essential for precise diagnosis by . The aim the present study was to evaluate optimal staining method colon. Methods Thirty prospectively enrolled patients were allocated 1:1:1 three distinct methods: 0.05% crystal violet CV alone, 1% methylene blue MB or + CM double). Normal rectal mucosae stained with each dye videos recorded....
Pit pattern (PIT) diagnosis with magnifying chromoendoscopy is effective diagnostic method for predicting a massively invasive submucosal colorectal cancer (SMm) which has possibility of metastasis, whereas endocytoscopy (EC) recently reported to provide excellent ability by enabling in vivo cellular visualization. The aim was assess the additional value EC PIT diagnosing lesions.We conducted retrospective comparative analysis using prospectively recorded database referral hospital. subjects...
Abstract Purpose Although some studies have reported differences in clinicopathological features between left- and right-sided advanced colorectal cancer (CRC), there are few reports regarding early-stage disease. In this study, we aimed to compare the of T1 CRC. Methods Subjects were 1142 cases with CRC undergoing surgical or endoscopic resection 2001 2018 at Showa University Northern Yokohama Hospital. Of these, 776 left-sided (descending colon rectum) 366 (cecum transverse colon). We...
