RESUMEN
INTRODUCTION: Quality metrics for inpatient cirrhosis management have been created to improve processes of care. We aimed to improve adherence to quality metrics by creating a novel clinical decision support (CDS) tool in the electronic health record (EHR). METHODS: We developed and piloted an alert system in the EHR that directs providers to a cirrhosis order set for patients who have a known diagnosis of cirrhosis or are likely to have cirrhosis. Adherence to process measures and outcomes when the CDS was used were compared with baseline performance before the implementation of the CDS. RESULTS: The use of the order set resulted in a significant increase in adherence to process measures such as diagnostic paracentesis (29.6%-51.1%), low-sodium diet (34.3%-77.8%), and social work involvement (36.6%-88.9%) ( P < 0.001 for all). There were also significant decreases in both intensive care and hospital lengths of stay ( P < 0.001) as well as in-hospital development of infection ( P = 0.002). There was no difference in hospital readmissions at 30 or 90 days between the groups ( P = 0.897, P = 0.640). DISCUSSION: The use of CDS in EHR-based interventions improves adherence to quality metrics for patients with cirrhosis and could easily be shared by institutions through EHR platforms. Further studies and larger sample sizes are needed to better understand its impact on additional outcome measures.

BACKGROUND AND AIMS: Amid the COVID-19 pandemic, medical education organizations endorsed a virtual recruitment format, representing a stark change from traditional in-person interviews. We aimed to identify the attitudes and perceptions of Gastroenterology Fellowship Program Directors (PDs) and applicants regarding the virtual interview experience and the role of virtual interviews (VI) in the future. METHODS: We designed separate surveys targeting PDs and applicants using the Qualtrics software. At the end of the interview season, we e-mailed both survey links to all PDs and requested that they forward the applicant survey to their interviewed candidates. Surveys were voluntary and anonymous. Descriptive statistics were used to analyze the data with results presented as percentages. RESULTS: A total of 29.7% of PDs completed the survey. Compared to traditional interviews, VI were viewed by 46.5% of PDs to be very suboptimal or suboptimal. Yet, 69.1% envisioned a role for VI in the future. A total of 14.2% of applicants completed the survey. Compared to traditional interviews, VI were viewed by 42.3% of applicants to be very suboptimal or suboptimal. However, 61.8% saw a future role for VI. While both applicants and PDs reported that establishing an interpersonal connection was a disadvantage with VI, applicants placed more emphasis on this need for connection (p = 0.001). CONCLUSION: Overall, PDs and applicants report mixed views with regard to VI but anticipate that it may continue to have a future role. VI may augment future recruitment cycles with care taken to not disadvantage applicants, who rely heavily on the interview process to create personal connections with programs.

BACKGROUND: Blue light imaging (BLI) has been shown to improve the characterization of colorectal polyps among the endoscopy experts. We aimed to determine if this technology could be taught to endoscopy trainees while maintaining high accuracy and interobserver agreement. METHODS: Twenty-one gastroenterology trainees (fellows) from two academic institutions participated in this prospective study. Each trainee completed a web-based learning comprising four modules: pre-test, didactic videos explaining the BLI Adenoma Serrated International Classification (BASIC), interactive examples, and post-test assessment. The pre- and post-test modules consisted of reviewing video images of colon polyps in high definition white light imaging and BLI and then applying the BASIC classification to determine if the polyps were likely to be adenomatous. Confidence in adenoma identification (rated '1' to '5'), accuracy in polyp (adenoma vs. non-adenoma) identification, and agreement in characterization per BASIC criteria were derived. RESULTS: Trainee accuracy in the adenoma diagnosis improved from 74.7% (pre-test) to 85.4% (post-test) (P < 0.01). There was a trend towards higher accuracy in polyp characterization with subsequent years of training (1st year fellows 77.4%, 2nd year 88.5%, and final year 94.0%) with consistent improvements after the e-learning across years of trainees. Overall, trainees were able to identify adenoma with a high sensitivity of 86.9%, specificity 83.9%, positive predictive value of 84.4%, and negative predictive value of 86.5%. However, their interobserver agreement in adenoma diagnosis was moderate (k = 0.52). CONCLUSION: The novel BLI classification can be easily taught to gastroenterology trainees using an online module and accuracy improves with years of training reaching >90% for colorectal polyp characterization.

Barrett's esophagus (BE), a premalignant condition for the development of esophageal adenocarcinoma (EAC), is a consequence of chronic gastroesophageal reflux disease (GERD). Although the incidence of EAC is increasing, a similar trend for BE is not clear. We aimed to evaluate the prevalence of newly diagnosed BE over time in a cohort of patients presenting with GERD symptoms. Information was prospectively collected between 1998 and 2015 for patients presenting to the endoscopy unit at a tertiary referral center for their index upper endoscopy for evaluation of GERD symptoms. Patients were asked to complete a validated GERD questionnaire that documents the onset of GERD symptoms (heartburn and acid regurgitation) and grades the frequency and severity of symptoms experienced. Demographic information, body mass index (BMI), and use of aspirin, nonsteroidal anti-inflammatory drugs, acid suppression therapy if any, smoking, family history, and endoscopic findings: erosive esophagitis, BE, and hiatal hernia were recorded. Patients evaluated during 1998-2003 (control) were compared with those presented in subsequent years (3-year cohorts) using chi-square test, and a multivariable logistic regression model was used to evaluate independent predictors. A total of 1109 patients were included in the analysis: mean age 56.9 years (standard deviation [SD] 12.8), 83% Caucasian, 93% male, and mean BMI 29.8 (SD 5.5). Overall, 226 (20.3%) patients were diagnosed with BE, with a mean BE length of 2.1 cm (SD 2.6). There was a significant decrease in the prevalence of BE over time from 24.3% in 1998-2003 to 13.5% in 2013-2015 (P = 0.002). During the same time period, a significant increasing trend in proton pump inhibitor (PPI) (41.7%; 1998-2003 vs. 80.2%; 2013-2015) (P < 0.001) and aspirin (ASA) use (23.7%; 1998-2003 vs. 25.9%; 2013-2015) (P = 0.034) was noted. There was also a significant reduction in cigarette smoking. In a multivariable logistic regression model for predicting the presence of newly diagnosed BE, there was a significant effect of timeframe even after adjusting for confounding variables. The results of our study indicate that there has been a steady and significant decline in the prevalence of BE in GERD patients over the last 2 decades. During this same time period, there has been an accompanying increase in the use of PPI, aspirin therapy, and a reduction in smoking, all modifiable risk factors potentially contributing to the decreasing prevalence of BE. Whether this decreasing prevalence of BE will lead to a reduction in EAC remains to be seen.

BACKGROUND & AIMS: European guidelines recommend different surveillance intervals of non-dysplastic Barrett's esophagus (NDBE) based on segment length, as opposed to guidelines in the United States, which do recommend surveillance intervals based on BE length. We studied rates of progression of NDBE to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) in patients with short-segment BE using the definition of BE in the latest guidelines (length ≥1 cm). METHODS: We collected demographic, clinical, endoscopy, and histopathology data from 1883 patients with endoscopic evidence of NDBE (mean age, 57.3 years; 83.5% male; 88.1% Caucasians) seen at 7 tertiary referral centers. Patients were followed for a median 6.4 years. Cases of dysplasia or EAC detected within 1 year of index endoscopy were considered prevalent and were excluded. Unadjusted rates of progression to HGD or EAC were compared between patients with short (≥1 and <3) and long (≥3) BE lengths using log-rank tests. A subgroup analysis was performed on patients with a documented Prague C&M classification. We used a multivariable proportional hazards model to evaluate the association between BE length and progression. Adjusted hazards ratios were calculated after adjusting for variables associated with progression. RESULTS: We found 822 patients to have a short-segment BE (SSBE) and 1061 to have long segment BE (LSBE). We found patients with SSBE to have a significantly lower annual rate of progression to EAC (0.07%) than of patients with LSBE (0.25%) (P = .001). For the combined endpoint of HGD or EAC, annual progression rates were significantly lower among patients with SSBE (0.29%) compared to compared to LSBE (0.91%) (P < .001). This effect persisted in multivariable analysis (hazard ratio, 0.32; 95% CI, 0.18-0.57; P < .001). CONCLUSION: We analyzed progression of BE (length ≥1 cm) to HGD or EAC in a large cohort of patients seen at multiple centers and followed for a median 6.4 years. We found a lower annual rate of progression of SSBE to EAC (0.07%/year) than of LSBE (0.25%/year). We propose lengthening current surveillance intervals for patients with SSBE.

BACKGROUND AND AIMS: Right-sided lesions are often missed during standard colonoscopy (SC). A second forward-view examination or retroflexion in the right side of the colon have both been proposed as techniques to improve adenoma detection rate (ADR) in the right side of the colon. Comparative data on examining the right side of the colon with a second forward view or retroflexion is not known in a pooled analysis. We performed a systematic review of the literature to assess the yield of a second forward view compared with retroflexion examination for the detection of right-sided adenomas. METHODS: A systematic literature search was performed using the following databases: PubMed, Embase, Web of Science, and Cochrane. Only full-length published articles that provided information on adenoma detection and miss rates during either a second forward view or retroflexed view of the right side of the colon after the initial standard forward withdrawal (SC) were included. The following outcomes were assessed: comparison of adenoma miss rate (AMR) for second forward view versus retroflexion after SC, AMR of SC compared with second forward view, AMR of SC compared with retroflexion, and right-sided adenoma detection with second forward view and retroflexion. Pooled rates were reported as risk difference or odds ratios (OR) with 95% confidence intervals (CI) with a P value <.05 indicating statistical significance. Statistical analysis was performed with Review Manager v5.3. RESULTS: We identified 4 studies with 1882 patients who underwent a second forward view of the right side of the colon after an initial SC. The average age of the patients was 58.3 years. Data on right-sided ADR were available from all 4 studies for the second forward view; however, only 2 of the studies provided information on right-sided ADR with retroflexion. The pooled estimate of AMR of a single SC was 13.3% (95% CI, 6.6%-20%) compared with a second forward-view examination (n = 4), whereas it was 8.1% (3.7%-12.5%) compared with a retroflexion examination (n = 3). However, when the second forward view was compared with retroflexion in terms of AMR from an analysis of 3 eligible studies, there was no statistically significant difference (7.3% vs 6.3%; pooled OR, 1.2; 95% CI, 0.9-1.61; P = .21). Second forward view of the right side of the colon increased the right-sided ADR by 10% (n = 4; second forward view vs SC, 33.6% vs 26.7%) with a pooled risk difference of 0.09 (95% CI, 0.03-0.15; P < .01). Retroflexion increased the right-sided ADR by 6% (n = 3; retroflexion vs SC, 28.4% vs 22.7%) with a pooled risk difference of 0.06 (95% CI, 0.03-0.09; P < 01). CONCLUSION: After SC withdrawal, a second forward view and retroflexed view of the right side of the colon are both associated with improvement in ADR. One of these techniques should be considered during SC to increase ADR and to improve the quality of colonoscopy.

INTRODUCTION: Data on time trends of dysplasia and esophageal adenocarcinoma (EAC) in Barrett's esophagus (BE) during the index endoscopy (ie, prevalent cases) are limited. Our aim was to determine the prevalence patterns of BE-associated dysplasia on index endoscopy over the past 25 years. METHODS: The Barrett's Esophagus Study is a multicenter outcome project of a large cohort of patients with BE. Proportions of patients with index endoscopy findings of no dysplasia (NDBE), low-grade dysplasia (LGD), high-grade dysplasia (HGD), and EAC were extracted per year of index endoscopy, and 5-yearly patient cohorts were tabulated over years 1990 to 2010+ (2010-current). Prevalent dysplasia and endoscopic findings were trended over the past 25 years using percentage dysplasia (LGD, HGD, EAC, and HGD/EAC) to assess changes in detection of BE-associated dysplasia over the last 25 years. Statistical analysis was done using SAS version 9.4 software (SAS, Cary, NC). RESULTS: A total of 3643 patients were included in the analysis with index endoscopy showing NDBE in 2513 (70.1%), LGD in 412 (11.5%), HGD in 193 (5.4%), and EAC in 181 (5.1%). Over time, there was an increase in the mean age of patients with BE (51.7 ± 29 years vs 62.6 ± 11.3 years) and the proportion of males (84% vs 92.6%) diagnosed with BE but a decrease in the mean BE length (4.4±4.3 cm vs 2.9±3.0 cm) as time progressed (1990-1994 to 2010-2016 time periods). The presence of LGD on index endoscopy remained stable over 1990 to 2016. However, a significant increase (148% in HGD and 112% in EAC) in the diagnosis of HGD, EAC, and HGD/EAC was noted on index endoscopy over the last 25 years (P < .001). There was also a significant increase in the detection of visible lesions on index endoscopy (1990-1994, 5.1%; to 2005-2009, 6.3%; and 2010+, 16.3%) during the same period. CONCLUSION: Our results suggest that the prevalence of HGD and EAC has significantly increased over the past 25 years despite a decrease in BE length during the same period. This increase parallels an increase in the detection of visible lesions, suggesting that a careful examination at the index examination is crucial.

BACKGROUND: Although shorter lengths of Barrett's esophagus (BE) have been associated with a lower risk of neoplastic progression, precise estimates have varied, especially for non-dysplastic BE (NDBE) only. Therefore, current US guidelines do not provide specific recommendations on surveillance intervals based on BE length. We performed a systematic review and meta-analysis of the published literature to examine neoplastic progression rates of NDBE based on BE length. METHODS: PubMed, Cochrane, Google Scholar, and Embase were comprehensively searched. Studies reporting progression rates in patients with NDBE and >â1 year of follow-up were included. The number of patients progressing to esophageal adenocarcinoma (EAC) and high grade dysplasia (HGD)/EAC in individual studies and the mean follow-up were recorded to derive person-years of follow-up.âPooled rates of progression to EAC and HGD/EAC based on BE length (<â3âcm vs. ≥â3âcm) were calculated. RESULTS: Of the 486 initial studies identified, 10 met the inclusion/exclusion criteria. These included a total of 4097 NDBE patients; 1979 with short-segment BE (SSBE; 10â773 person-years of follow-up) and 2118 with long-segment BE (LSBE; 12â868 person-years). The annual rates of progression to EAC were significantly lower for SSBE compared with LSBE: 0.06â% (95â% confidence interval 0.01â%â-â0.10â%) vs. 0.31â% (0.21â%â-â0.40â%), respectively; odds ratio (OR) 0.25 (0.11â-â0.56); Pâ<â0.001, as were the rates for the combined endpoint (HGD/EAC): 0.24â% (0.09â%â-â0.32â%) vs. 0.76â% (0.43â%â-â0.89â%), respectively; OR 0.35 (0.21â-â0.58); Pâ<â0.001. There was no significant heterogeneity among studies. CONCLUSION: The results demonstrate significantly lower rates of neoplastic progression in NDBE patients with SSBE compared with LSBE. BE length can easily be used for risk stratification purposes for NDBE patients undergoing surveillance endoscopy and consideration should be given to tailoring surveillance intervals based on BE length in future US guidelines.

PURPOSE OF REVIEW: In this review, we discuss different endoscopic techniques in the eradication of Barrett's esophagus (BE) as well as some controversies in the field of treatment. RECENT FINDINGS: Patients with T1a esophageal adenocarcinoma and BE of high-grade dysplasia should undergo endoscopic ablative therapy. The most studied technique to date is radiofrequency ablation. It can be combined with endoscopic mucosal resection in cases containing nodular and flat lesions. Cryotherapy and APC have shown promise with good efficacy and safety profiles so far, but are not mainstream as more studies are needed. Surveillance is still required post-ablation since recurrence is common. Low-grade dysplasia can be treated with either endo-ablative therapy or surveillance. Non-dysplastic BE treatment is controversial and so far, only surveillance is recommended. Research is ongoing to better risk stratify these patients. Our ability to diagnose and treat BE has come a long way in the past few years with the goal of preventing its progression into malignancy. The advent of endoscopic techniques in the eradication of BE has provided a less invasive and safer modality of treatment as compared to surgical esophagectomy. Data in the form of randomized trials and high-volume registries has provided good evidence to support the efficacy of these techniques and their long-term durability.

Background: Barrett's esophagus (BE) and dysplasia are often missed by Seattle protocol biopsies (SPB). Wide-area transepithelial sampling with 3-dimensional computer-assisted analysis (WATS-3D) with SPB improves detection in treatment-naïve patients. We aimed to determine to what extent WATS-3D adds to SPB in the detection of non-dysplastic BE (NDBE) and dysplasia in patients undergoing post-endoscopic eradication therapy (EET). Methods: This retrospective, observational, cross-sectional study included patients who presented for post-EET surveillance with SPB and WATS-3D sampling from April 2019 to February 2020. BE patients with no previous EET were excluded. For the outcomes of NDBE and any dysplastic/neoplastic finding, we calculated both relative and absolute increases in yield by WATS-3D over SBP. Results: In 78 patients [mean age 68±10.4 years, 66 (84.6%) male], the prevalence of NDBE, any dysplastic/neoplastic finding, and any abnormality (NDBE or dysplasia/neoplasia) were 53.85%, 10.26%, and 55.13%. The absolute increase in yield of NDBE with WATS-3D over SPB was 26.9% (95% confidence interval [CI] 17.95-37.18%), with the number needed to treat (NNT) 3.71 (95%CI 2.69-5.57) and a relative increase in yield of 100% (95%CI 53.33-188.25%). For dysplasia/neoplasia, the absolute increase in yield was 6.4% (95%CI 1.28-12.82%), NNT 15.6 (95%CI 7.8-78.0), and relative increase of 167% (95%CI 33.33%-infinity). For any abnormal finding, the absolute increase in yield was 26.9% (95%CI 16.67-37.18%), NNT 3.71 (95%CI 2.69-6.00), and relative increase in yield 95% (95%CI 50-176.92%). Conclusions: WATS-3D with SPB improves the detection of residual/recurrent BE and dysplasia in post-ablation BE. However, randomized controlled trials are needed to validate these findings.
RESUMEN
Despite advances in endoscopic imaging modalities, there are still significant miss rates of dysplasia and cancer in Barrett's esophagus. Artificial intelligence (AI) is a promising tool that may potentially be a useful adjunct to the endoscopist in detecting subtle dysplasia and cancer. Studies have shown AI systems have a sensitivity of more than 90% and specificity of more than 80% in detecting Barrett's related dysplasia and cancer. Beyond visual detection and diagnosis, AI may also prove to be useful in quality control, streamlining clinical work, documentation, and lessening the administrative load on physicians. Research in this area is advancing at a rapid rate, and as the field expands, regulations and guidelines will need to be put into place to better regulate the growth and use of AI. This review provides an overview of the present and future role of AI in Barrett's esophagus.
RESUMEN
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.
