Patient-Reported Outcomes and Preferences for Colon Capsule Endoscopy and Colonoscopy: A Systematic Review with Meta-Analysis

Colon capsule endoscopy as an alternative to colonoscopy for the diagnosis of colonic disease may be a less costly and more tolerable investigation for patients. Our aim was to review patient-reported outcomes for colon capsule endoscopy compared to traditional optical colonoscopy, including the choice of investigation modality, tolerability, and adverse events. Patients with out of fourteen included studies, twelve had investigated patient-reported outcomes in patients who had undergone both investigations, and in two, the patients were randomized between studies. The patient preferences for colon capsule endoscopy and 45% for traditional colonoscopy were expected to be 52% and 45% for conventional colonoscopy, not indicating a significant difference. Both colon capsule endoscopy and conventional colonoscopy had a high tolerability. Patients' preferences for both colonoscopy and colon capsule endoscopy were not significantly different. Procedural adverse events were unusual, and colon capsule endoscopy tolerability was consistently reported at a much greater degree than that of conventional colonoscopy.

From labels to priors in capsule endoscopy: a prior guided approach for improving generalization with few labels

Abstract: The lack of generalizability of deep learning methods for the automated diagnosis of pathologies in wireless Capsule Endoscopy has denied any significant advances from trickling down to current clinical research. As a result, disease control using WCE continues to rely on extensive manual studies by medical specialists. Domain priors can benefit representations by acting in proxy of brands, thus dramatically lowering the labeling requirement while still encouraging fully unsupervised yet pathology-aware learning.

Performance of PILLCAMSB3 Video-Capsule Endoscopy in the Diagnosis of the Non-Small Bowel Hemorrhagic Lesions Undetected by Upper and Lower Digestive Endoscopy

Our aim is to assess the diagnostic results of VCE after a non-conclusive upper and lower digestive endoscopy, as well as the comfort and diagnostic efficiency of this device. Materials and Methods: We include all patients who underwent a Pillcam SB3 VCE from July 2018 to Semptember 2022, according to this multicentric and descriptive review, including both gastroscopy and ileocoloscopy. 40% of the patients had persistent renal disease, 13% had a portal hypertension, 13% had a history of heart disease, 13% had a history of heart disease, and 6% had a Rendu-Osler disease. The VCE was diagnosed with symptoms and symptoms for a long time. The diagnostic yield of VCE in non-small bowel hemorrhagic lesions was 25 percent. However, we suspect that the first upper and lower digestive endoscopies in patients with digestive bleeding/anemia and/or anemia may have triggered the repetition of the conventional endoscopies before performing VCE.

Machine learning techniques to detect bleeding frame and area in wireless capsule endoscopy video

This report reveals a new way to color extraction to distinguish bleeding frames from normal ones and find more bleeding regions. To get the clustered centers that frame WCE photos as words, we use complete color information on the WCE images and the pixel-based clustering strategy. Second, we introduce a two-step strategy for extracting saliency maps to highlight bleeding places with a distinct color channel mixer to produce a first-stage salience map. Following a proper fusion strategy and threshold, we find bleeding points on the second stage salience map, which was captured with optical clarity.

Video Capsule Endoscopy: Is Bowel Preparation Necessary?

The aim of our investigation was to see if there was a statistical correlation between small bowel mucosal visualization rates for those who were bowel preparation and those who did not. Small bowel mucosal visualization rates were similar between those who underwent bowel preparation and those that did not. In patients who had a long fast compared to those who had a shorter fast, tiny bowel mucosal visualization rates were significantly higher. The addition of bowel preparation prior to video capsule endoscopy does not significantly improve small bowel mucosal visualization rates, and, in addition, there is a statistically significant association between increased fasting time and improved small bowel mucosal visualization. A prolonged fast without bowel preparation may be useful for an accurate small bowel visualization, but more randomized, prospective studies are needed to confirm these results.

Wireless fluorescence capsule for endoscopy using single photon-based detection

Abstract Fluorescence Imaging is a common tool in biological science and clinical medicine. Here we have a miniaturized wireless fluorescence endoscope capsule with low power consumption that will help with future FI systems and applications. With enhanced sensitivity compared to previous methods, we have found that the capsule can be used to image tissue autofluorescence and targeted fluorescence by fluorophore labeling of tissues. We also demonstrated the use of marker identification by using a 20 bcM fluorescein isothiocyanate labelling solution on mammalian tissue.

Multi-scale Features Fusion for the Detection of Tiny Bleeding in Wireless Capsule Endoscopy Images

A new non-invasive Internet of Medical Imaging Things that has increasingly been used in gastrointestine research is a wireless capsule endoscopy. Automatic lesion detection is highly recommended to increase the accuracy of the diagnosis procedure and reduce human errors in each examination, with around one gigabyte image data generated for a patient in each examination. As bleeding lesions are a common occurrence in most common gastrointestinal diseases, finding tiny bleeding lesions early in pregnancy is extremely important for early diagnosis of those diseases that are highly related to patient survival, care, and costs. First used as our backbone network to extract the key features from wireless capsule endoscopy photos, then multiple regions could be identified as potential lesions, and then at each layer several regions could be identified as potential lesions. In addition, our model also has the highest AP and the highest medical diagnosis results when compared to state-of-the-art multi-scale models.

The Effectiveness of a Very Low-Volume Compared to High-Volume Laxative in Colon Capsule Endoscopy

Colon capsule endoscopy is a promising method for colonic studies, but completion rates and adequate cleansing rates must be enhanced to meet established optical colonoscopy requirements. We wanted to compare a low-volume polyethylene glycol laxative to a traditional high-volume laxative. Patients referred to CCE were included in a single-center retrospective comparative cohort study. In the high-volume group, the CR and ACR were 77% and 67% respectively, and 72% and 75% in the very low-volume group. Prior to CCE in terms of CR and ACR, a low-volume bowel preparation regimen was non-inferior to a high-volume regiment.

The Impact of Metabolic Risk Factors, Diabetes, Medications, and Comorbid Illness on Transit Time at Capsule Endoscopy: A Prospective Cohort Study

Background: Video capsule endoscopy is a safe and effective way to look into obscure gastrointestinal bleeding. Suboptimal visualization is one of the key VCE's key drawbacks, and there is no such time for rapid intestinal transit time. Conclusions: Significant predictors of decreased GTT were increasing age and use of beta blocker drugs, which were both expected predictors of reduced GTT. Increasing GTT, serum glucose > 5mmol/L, obesity, and diabetes were among the predictors of reduced SITT on univariate analysis. On multivariate analysis, increased GTT and glucose were still significant. GTT is reduced by beta-blocker therapy, according to the researchers. Hyperglycaemia at the time of VCE reduces SITT.
