Design and Evaluation of ScanCap: A Low-Cost, Reusable Tethered Capsule Endoscope with Blue-Green Illumination Imaging for Unsedated Screening and Early Detection of Barrett's Esophagus. Bioengineering (Basel) 2024; 11:557. [PMID: 38927792 PMCID: PMC11200367 DOI: 10.3390/bioengineering11060557] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 05/15/2024] [Accepted: 05/19/2024] [Indexed: 06/28/2024] Open
Abstract
Esophageal carcinoma is the sixth-leading cause of cancer death worldwide. A precursor to esophageal adenocarcinoma (EAC) is Barrett's Esophagus (BE). Early-stage diagnosis and treatment of esophageal neoplasia (Barrett's with high-grade dysplasia/intramucosal cancer) increase the five-year survival rate from 10% to 98%. BE is a global challenge; however, current endoscopes for early BE detection are costly and require extensive infrastructure for patient examination and sedation. We describe the design and evaluation of the first prototype of ScanCap, a high-resolution optical endoscopy system with a reusable, low-cost tethered capsule, designed to provide high-definition, blue-green illumination imaging for the early detection of BE in unsedated patients. The tethered capsule (12.8 mm diameter, 35.5 mm length) contains a color camera and rotating mirror and is designed to be swallowed; images are collected as the capsule is retracted manually via the tether. The tether provides electrical power and illumination at wavelengths of 415 nm and 565 nm and transmits data from the camera to a tablet. The ScanCap prototype capsule was used to image the oral mucosa in normal volunteers and ex vivo esophageal resections; images were compared to those obtained using an Olympus CV-180 endoscope. Images of superficial capillaries in intact oral mucosa were clearly visible in ScanCap images. Diagnostically relevant features of BE, including irregular Z-lines, distorted mucosa, and dilated vasculature, were clearly visible in ScanCap images of ex vivo esophageal specimens.

Abstract
Gastrointestinal cancers are characterized by high incidence and mortality. However, there are well-established methods of screening. The endoscopy exam provides the macroscopical image and enables harvesting the tissue samples for further histopathological diagnosis. The efficiency of endoscopies relies not only on proper patient preparation, but also on the skills of the personnel conducting the exam. In recent years, a number of reports concerning the application of artificial intelligence (AI) in medicine have arisen. Numerous studies aimed to assess the utility of deep learning/ neural network systems supporting endoscopies. In this review, we summarized the most recent reports and randomized clinical trials regarding the application of AI in screening and surveillance of gastrointestinal cancers among patients suffering from esophageal, gastric, and colorectal cancer, along with the advantages, limitations, and controversies of those novel solutions.

Abstract
Background The prevalence of Barrett's esophagus (BE) in African Americans (AA) is uncertain. However, several potential risk factors, includes family history, male sex, ethnicity, chronic heartburn and acid reflux, age over 60, current or past smoking, and obesity are associated with BE. The aim of this study is to determine the incidence of BE in AA patients who underwent Esophageal Gastro Endoscopy (EGD). Methods Medical and demographic data of 1,253 AA patients with various symptoms, including BE, Esophageal adenocarcinoma (EAC), esophageal squamous adenocarcinoma (SCC), hiatal hernia, H. pylori infection, Gastro-Esophageal Reflux Disease (GERD), Gastritis, and esophagitis, were collected from January 2004 to December 2014 at Howard University Hospital. Results Among the 1,253 patients, the median age was 61 and 49% were male out of the total. The frequencies of EAC (p= 0.05), and SCC (p= 0.002) were significantly high in males, along with SCC frequency significantly increased with older age (p<0.001). Furthermore, esophageal polyps with hiatal hernia (p=0.008) and H. pylori (p=<0.001) were found to be associated with esophagitis, and its presence may contribute to the development of BE. Conclusion The findings highlighted the high prevalence of GERD symptoms and pathologic gastritis along with EAC was less common than SCC and both types of esophageal cancer were associated with male gender and older age whereas, H. pylori infection was identified as a risk factor for pathologic gastritis in AA. Overall data emphasize the need for extensive research, increased awareness, diagnosis, and management of GERD, gastritis, and related conditions to uncover the underlying mechanisms and factors contributing to these conditions in the AA population.

High rate of missed Barrett's esophagus when screening with forceps biopsies. Esophagus 2023; 20:143-149. [PMID: 35864425 PMCID: PMC9813185 DOI: 10.1007/s10388-022-00943-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Accepted: 07/11/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND Screening for Barrett's esophagus (BE) with endoscopy plus forceps biopsy (FB) has poor compliance with the recommended Seattle protocol and fails to sample large areas of mucosa. This statistical modeling study estimates, for the first time, the actual frequency of missed BE cases by FB. METHODS Published, calibrated models in the literature were combined to calculate the age-specific prevalence of BE in white males with gastroesophageal reflux disease (GERD). We started with estimates of the prevalence of BE and GERD, and applied the relative risk for BE in patients with GERD based on the literature. This created estimates of the true prevalence of BE in white males with GERD by decade of life. The proportion of BE missed was calculated as the difference between the prevalence and the proportion with a positive screen. RESULTS The prevalence of BE in white males with GERD was 8.9%, 12.1%, 15.3%, 18.7% and 22.0% for the third through eighth decades of life. Even after assuming no false positives, missed cases of BE were about 50% when estimated for patients of ages 50 or 60 years, and over 60% for ages of 30, 40 or 70 years. Sensitivity analysis was done for all variables in the model calculations. For ages 50 and 60 years, this resulted in values from 30.3 to 57.3% and 36.4 to 60.9%. CONCLUSION Screening for BE with endoscopy and FB misses approximately 50% of BE cases. More sensitive methods of BE detection or better adherence to the Seattle protocol are needed.

Abstract
Introduction Esophageal adenocarcinoma (EAC) is one of the histologic types of esophageal cancer with a poor prognosis. The majority of EAC originate from Barrett's esophagus (BE). There are few studies focusing on the dynamic progression of BE to EAC. Methods R software was used to analyze differentially expressed genes (DEGs) based on RNA-seq data of 94 normal esophageal squamous epithelial (NE) tissues, 113 BE tissues and 147 EAC tissues. The overlapping genes of DEGs between BE and EAC were analyzed by Venn diagram tool. The hub genes were selected by Cytoscape software based on the protein-protein interaction network of the overlapping genes using STRING database. The functional analysis of hub genes was performed by R software and the protein expression was identified by immunohistochemistry. Results In the present study, we found a large degree of genetic similarity between BE and EAC, and further identified seven hub genes (including COL1A1, TGFBI, MMP1, COL4A1, NID2, MMP12, CXCL1) which were all progressively upregulated in the progression of NE-BE-EAC. We have preliminarily uncovered the probable molecular mechanisms of these hub genes in disease development and constructed the ceRNA regulatory network of hub genes. More importantly, we explored the possibility of hub genes as biomarkers in the disease progression of NE-BE-EAC. For example, TGFBI can be used as biomarkers to predict the prognosis of EAC patients. COL1A1, NID2 and COL4A1 can be used as biomarkers to predict the response to immune checkpoint blockade (ICB) therapy. We also constructed a disease progression risk model for NE-BE-EAC based on CXCL1, MMP1 and TGFBI. Finally, the results of drug sensitivity analysis based on hub genes showed that drugs such as PI3K inhibitor TGX221, bleomycin, PKC inhibitor Midostaurin, Bcr-Abl inhibitor Dasatinib, HSP90 inhibitor 17-AAG, and Docetaxel may be potential candidates to inhibit the progression of BE to EAC. Conclusion This study is based on a large number of clinical samples with high credibility, which is useful for revealing the probable carcinogenic mechanism of BE to EAC and developing new clinical treatment strategies.

[PMID: 36034104 PMCID: PMC9403448 DOI: 10.1177/20406223221117971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 07/19/2022] [Indexed: 11/25/2022] Open
Abstract
Background and Aims: Barrett’s esophagus (BE) is the only recognized precursor for esophageal
adenocarcinoma. Helicobacter pylori (H.
pylori) infection is a major contributing factor towards upper
gastrointestinal diseases, but its relationship with BE remains
controversial. Some previous studies suggested that H.
pylori infection negatively correlated with BE, while others
did not. This may be attributed to the difference in the selection of
control groups among studies. The present meta-analysis aims to clarify
their association by combining all available data from well-designed
studies. Methods: The PubMed, EMBASE, and Cochrane
Library databases were searched. Odds ratios (ORs) with 95%
confidence intervals (CIs) were pooled by a random-effects model.
Heterogeneity was evaluated using the Cochran’s Q test and
I2 statistics. Meta-regression, subgroup,
and leave-one-out sensitivity analyses were employed to explore the sources
of heterogeneity. Results: Twenty-four studies with 1,354,369 participants were included. Meta-analysis
found that patients with BE had a significantly lower prevalence of
H. pylori infection than those without (OR = 0.53, 95%
CI = 0.45–0.64; p < 0.001). The heterogeneity was
statistically significant (I² = 79%;
p < 0.001). Meta-regression, subgroup, and leave-one-out
sensitivity analyses did not find any source of heterogeneity. Meta-analysis
of 7 studies demonstrated that CagA-positive H. pylori
infection inversely correlated with BE (OR = 0.25, 95% CI = 0.15–0.44;
p = 0.000), but not CagA-negative H.
pylori infection (OR = 1.22, 95% CI = 0.90–1.67;
p = 0.206). Meta-analysis of 4 studies also
demonstrated that H. pylori infection inversely correlated
with LSBE (OR = 0.39, 95% CI = 0.18–0.86; p = 0.019), but
not SSBE (OR = 0.73, 95% CI = 0.30–1.77; p = 0.484). Conclusion: H. pylori infection negatively correlates with BE. More
experimental studies should be necessary to elucidate the potential
mechanisms in future.

Abstract
More than 600,000 people are diagnosed with esophageal cancer (EC) every year globally, and the five-year survival rate of EC is less than 20%. Two common histological subtypes of EC, esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC), have great geographical variations in incidence rates. About half of the world's EC was diagnosed in China and a majority of which belong to ESCC. Globally, the overall incidence rate of EC is decreasing. In some high-risk Asian regions, such as China, the incidence rate of ESCC has generally declined, potentially due to economic growth and improvement of diet habits. In some European high-income countries and the United States, the decline is mainly attributed to the decrease in smoking and drinking. The risk factors of EC are not well understood, and the importance of environmental and genetic factors in the pathogenesis is also unclear. The incidence and mortality of advanced EC can be reduced through early diagnosis and screening. White light endoscopy is still the gold standard in the current screening technology. This article reviews the epidemiology, risk factors, and screening strategies of EC in recent years to help researchers determine the most effective management strategies to reduce the risk of EC.

Abstract
Barrett’s esophagus is the condition in which a metaplastic columnar epithelium
replaces the stratified squamous epithelium that normally lines the distal
esophagus. The condition develops as a consequence of chronic gastroesophageal
reflux disease and predisposes the patient to the development of esophageal
adenocarcinoma. The diagnosis and management of Barrett’s esophagus have
undergone dramatic changes over the years and continue to evolve today.
Endoscopic eradication therapy has revolutionized the management of dysplastic
Barrett’s esophagus and early esophageal adenocarcinoma by significantly
reducing the morbidity and mortality associated with the prior gold standard of
therapy, esophagectomy. The purpose of this review is to highlight current
principles in the management and endoscopic treatment of this disease.

Systematic review with meta-analysis: neoplasia detection rate and post-endoscopy Barrett's neoplasia in Barrett's oesophagus. Aliment Pharmacol Ther 2021; 54:546-559. [PMID: 34275161 PMCID: PMC9152697 DOI: 10.1111/apt.16531] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 02/17/2021] [Accepted: 06/29/2021] [Indexed: 12/30/2022]
Abstract
BACKGROUND Neoplasia detection rate, the proportion of Barrett's oesophagus patients with high-grade dysplasia or oesophageal adenocarcinoma detected at index surveillance endoscopy has been proposed as a quality metric. However, the correlation between neoplasia detection rate and a clinically relevant outcome like post-endoscopy Barrett's neoplasia remains unknown. Post-endoscopy Barrett's neoplasia refers to the rate of high-grade dysplasia or oesophageal adenocarcinoma on repeat endoscopy within one year of an index screening examination revealing non-dysplastic Barrett's oesophagus or low-grade dysplasia. AIM To assess correlation between neoplasia detection rate and post-endoscopy Barrett's neoplasia. METHODS We performed a systematic search of multiple databases from date of inception to June 2021 to identify cohort studies reporting both neoplasia detection rate and post-endoscopy Barrett's neoplasia. Data from each study were pooled using a random effects model, and their correlation assessed using meta-regression. Heterogeneity was assessed and a priori planned subgroup analyses were conducted. RESULTS Ten studies with 27 894 patients with Barrett's oesophagus were included. The pooled neoplasia detection rate and post-endoscopy Barrett's neoplasia were 5.0% (95% CI: 3.4%-7.1%, I2 = 97%) and 19.6% (95% CI: 10.1%-34.7%, I2 = 96%), respectively. Meta-regression revealed a statistically significant inverse relationship between the two variables (coefficient -3.50, 95% CI: -4.63 to -2.37, P < 0.01). With every 1% increase of neoplasia detection rate, post-endoscopy Barrett's neoplasia decreased by 3.50%. Heterogeneity was high despite adjusting for study quality and performing several subgroup analyses. CONCLUSION We observed a statistically significant inverse correlation between neoplasia detection rate and post-endoscopy Barrett's neoplasia. Additional studies are needed to further validate this correlation.

Abstract
Background: Helicobacter pylori is an important pathogen in the upper digestive tract. It is of great significance to properly understand the risk factors for the transformation of Barrett esophagus into esophageal carcinoma. However, the relationship between H. pylori and gastroesophageal reflux disease (GERD) and Barrett esophagus remains controversial, and the correlation with immune function has been rarely reported. Objectives: This study investigated the effect of H. pylori infection on Barrett esophagus and its correlation with immune function. Methods: We recruited 40 patients with Barrett esophagus (Barrett esophagus group) and 40 patients with GERD (GERD group). In addition, 40 healthy controls were selected for the control group. Esophageal function and its correlation with immune function were measured in each group. Results: The positivity rate of H. pylori (P < 0.05) and sphincter pressure were lower in both Barrett esophagus and GERD groups than in the control group, while the levels of PGI, PGII, PGI/II, and G-17 were higher (P < 0.05). The levels of CD3+, CD4+, and CD4+/CD8+ were lower in the Barrett esophagus group than in the GERD group, but they were negatively correlated (P < 0.05) with H. pylori infection. The level of CD8+ was higher in the Barrett esophagus group, and it was positively correlated (P < 0.05) with H. pylori infection. Conclusions: Helicobacter pylori infection may protect against Barrett esophagus by reducing gastric acid secretion and increasing lower esophageal sphincter pressure. Besides, it has a certain correlation with immune function.

Abstract
Background There are no evidence-based recommendations for performing upper gastrointestinal endoscopy (UGIE) in patients with extra-oesophageal symptoms of gastro-oesophageal reflux disease (GORD). However, UGIEs are often performed in clinical practice in these patients. We aimed to assess the prevalence of gastro-oesophageal lesions in patients with atypical GORD symptoms. Methods Patients complaining of at least one extra-oesophageal GORD symptom and undergoing UGIE in seven centres were prospectively enrolled. Clinically relevant lesions (Barrett's oesophagus, erosive oesophagitis, gastric precancerous conditions, peptic ulcer, cancer, and H. pylori infection) were statistically compared between groups regarding GORD symptoms (atypical vs. both typical and atypical), type of atypical symptoms, age, and presence of hiatal hernia. Results Two hundred eleven patients were enrolled (male/female: 74/137; mean age: 55.5 ± 14.7 years). Barrett's oesophagus was detected in 4 (1.9%), erosive oesophagitis in 12 (5.7%), gastric precancerous conditions in 22 (10.4%), and H. pylori infection in 38 (18%) patients. Prevalence of clinically relevant lesions was lower in patients with only atypical GORD symptoms (28.6 vs. 42.5%; p = 0.046; χ<sup>2</sup> test), in patients ≤50 years (20 vs. 44.8%; p = 0.004; χ<sup>2</sup> test), and in those in ongoing proton pump inhibitor (PPI) therapy (21.1 vs. 40.2%; p = 0.01; χ<sup>2</sup> test). No clinically relevant lesions were detected in patients ≤50 years, without alarm symptoms, and receiving PPI therapy. Hiatal hernia was diagnosed in only 6 patients with cardiologic and in 41 patients with ear-nose-throat symptoms (11.3 vs. 35.1%; p = 0.03; χ<sup>2</sup> test). Conclusions Clinically relevant lesions are uncommon among young (≤50 years) patients with extra-oesophageal GORD symptoms. Hiatal hernia is not more prevalent in patients with cardiologic symptoms and suspicion of GORD. The usefulness of UGIE in these patients is questionable.
