Barrett's esophagus (BE) is a common condition associated with chronic gastroesophageal reflux disease. BE is the only known precursor to esophageal adenocarcinoma, a highly lethal cancer with an increasing incidence over the last 5 decades. These revised guidelines implement Grading of Recommendations, Assessment, Development, and Evaluation methodology to propose recommendations for the definition and diagnosis of BE, screening for BE and esophageal adenocarcinoma, surveillance of patients with known BE, and the medical and endoscopic treatment of BE and its associated early neoplasia. Important changes since the previous iteration of this guideline include a broadening of acceptable screening modalities for BE to include nonendoscopic methods, liberalized intervals for surveillance of short-segment BE, and volume criteria for endoscopic therapy centers for BE. We recommend endoscopic eradication therapy for patients with BE and high-grade dysplasia and those with BE and low-grade dysplasia. We propose structured surveillance intervals for patients with dysplastic BE after successful ablation based on the baseline degree of dysplasia. We could not make recommendations regarding chemoprevention or use of biomarkers in routine practice due to insufficient data.

INTRODUCTION:Coronavirus Disease 2019 disrupted cancer-related care in early 2020.METHODS:We used population-based cancer registry data to estimate incidence and mortality rates of gastrointestinal cancers between 2016 and 2020.RESULTS:Incidence rates were unchanged from 2016 to 2019 but decreased in 2020, with the largest declines for colorectal cancer (rate ratio [RR] 0.88; 95% confidence interval [CI] 0.87-0.90) and hepatocellular carcinoma (RR 0.85; 95% CI 0.82-0.88). Mortality rates of colorectal cancer (RR 1.06; 95% CI 1.04-1.08) and esophageal adenocarcinoma (RR 1.06; 95% CI 1.00-1.13) increased in 2020.DISCUSSION:Incidence and mortality rates of gastrointestinal cancers may increase in the future given pandemic-related delays in 2020.

Abstract Diaphragmatic eventration (DE) is an abnormal condition where a portion or the entire hemidiaphragm elevates due to insufficient muscle or nerve function while maintaining its anatomical attachments. On the other hand, congenital diaphragmatic hernias occur due to the abnormal development of muscular entities of the diaphragm, resulting in the displacement of abdominal contents into the thorax. The difference between diaphragmatic hernia and eventration is important as there is no true defect in DE. Ruptured eventration of the diaphragm is a rare entity, with only three cases reported in adults in literature till date, all on the left side. We report the first case of ruptured eventration of the diaphragm on the right side, which was repaired by a combination of laparoscopy and thoracoscopy and with double-mesh placement.

Variability in adherence rates to the Seattle protocol and to surveillance interval recommendations, established quality indicators (QIs) in Barrett's esophagus (BE), is unknown. We evaluated endoscopist and site-based adherence rates to these QIs from January 2018 to May 2021 using the GI Quality Improvement Consortium national registry with matched endoscopy and pathology data. Across 153 practices with 572 endoscopists performing 20,155 endoscopies, adherence to the Seattle protocol varied by endoscopists (median 93.8%, IQR 18.9%) and by site (median 90.0%, IQR 20.1%). Adherence to appropriate surveillance intervals for nondysplastic BE also varied by endoscopist (median 82.4%, IQR 36.3%) and site (median 77.2%, IQR 29.8%). The overall dysplasia detection rate was 3.1% and varied among endoscopists and sites. These US population-based results can serve as a benchmark for quality initiatives and intervention trials aimed at improving outcomes for patients with BE.

Background White light endoscopy with random biopsies is the standard for detection of intestinal metaplasia (IM) and neoplasia in patients with Barrett's oesophagus (BO). Narrow band imaging (NBI) highlights surface patterns that correlate with IM and neoplasia in BO. Objective To compare high-definition white light (HD-WLE) and NBI for detection of IM and neoplasia in BO. Design International, randomised, crossover trial comparing HD-WLE and NBI. Patients referred for BO screening/surveillance at three tertiary referral centres were prospectively enrolled and randomised to HD-WLE or NBI followed by other procedures in 3–8 weeks. During HD-WLE, four quadrant biopsies every 2 cm, together with targeted biopsies of visible lesions (Seattle protocol), were obtained. During NBI examination, mucosal and vascular patterns were noted and targeted biopsies were obtained. All biopsies were read by a single expert gastrointestinal pathologist in a blinded fashion. Results 123 patients with BO (mean age 61; 93% male; 97% Caucasian) with mean circumferential and maximal extents of 1.8 and 3.6 cm, respectively, were enrolled. Both HD-WLE and NBI detected 104/113 (92%) patients with IM, but NBI required fewer biopsies per patient (3.6 vs 7.6, p<0.0001). NBI detected a higher proportion of areas with dysplasia (30% vs 21%, p=0.01). During examination with NBI, all areas of high-grade dysplasia and cancer had an irregular mucosal or vascular pattern. Conclusions NBI targeted biopsies can have the same IM detection rate as an HD-WLE examination with the Seattle protocol while requiring fewer biopsies. In addition, NBI targeted biopsies can detect more areas with dysplasia. Regular appearing NBI surface patterns did not harbour high-grade dysplasia/cancer, suggesting that biopsies could be avoided in these areas.

Guidelines recommend that patients with non-dysplastic Barrett's esophagus (NDBE) undergo surveillance endoscopy every 3-5 years. Using a national registry, we assessed compliance to recommended surveillance intervals in patients with NDBE and identified factors associated with compliance. We analyzed data from the GI Quality Improvement Consortium registry. Data abstracted include procedure indication, demographics, endoscopy/pathology results, and recommendations for future endoscopy. Patients with an indication of Barrett's esophagus (BE) screening or surveillance, or an endoscopic finding of BE, with non-dysplastic intestinal metaplasia on pathological examination, were included. Compliance was defined as a recommendation to undergo subsequent endoscopy between 3 and 5 years. Multivariate logistic regression was conducted to assess variables associated with compliance. Of 786,712 endoscopies assessed, 58,709 (7.5%) endoscopies in 53,541 patients met inclusion criteria (mean age 61.3 years, 60.4% men, 90.2% white, mean BE length was 2.3 cm). Most cases were performed by Gastroenterologists (92.3%) with propofol (78.7%). A total of 29,978 procedures (55.8%) resulted in pathology-confirmed BE. Among procedures with NDBE (n = 25,945), 29.9% were noncompliant with the 3-year threshold; most (26.9%) recommended surveillance at 1- to 2-year intervals. Patient factors such as extremes of age, black race, geographic region, type of sedation, and increasing BE length were associated with noncompliance. Approximately 30% of patients with NDBE are recommended to undergo surveillance endoscopy too soon. Patient factors associated with inappropriate utilization include extremes of age, black race, and increasing BE length. Compliance with appropriate endoscopic follow-up as a quality measure in BE is poor.

Background Gallstone disease poses a significant health burden in the United States. Choledocholithiasis and cholangitis are common complications of gallstone disease for which data on current epidemiological trends are lacking. We aimed to evaluate temporal changes in hospitalization, management, and outcomes for patients with choledocholithiasis and cholangitis. Methods The National Inpatient Sample was used to identify discharges for choledocholithiasis and cholangitis between 2005 and 2014. Temporal trends were evaluated via annual percent changes (APCs). Joinpoint regression was used to assess inflection points. Multivariable regression models were used to evaluate associations of interest. Results From 189,362 unweighted discharges for choledocholithiasis and/or cholangitis, there was an increase in discharges for choledocholithiasis (APC 2.3%, 95% confidence intervals, CI, 1.9–2.7%) and cholangitis (APC 1.5%, 95% CI 0.7–2.2%). Procedural interventions were more likely at urban hospitals for choledocholithiasis (adjusted odds ratio, aOR, 2.94, 95% CI 2.72 to 3.17) and cholangitis (aOR 2.97, 95% CI 2.50 to 3.54). In-hospital mortality significantly decreased annually for choledocholithiasis (aOR 0.90, 95% CI 0.88 to 0.93) and cholangitis (aOR 0.93, 95% CI 0.89 to 0.97). In-hospital mortality between rural and urban centers was comparable for choledocholithiasis (aOR 1.16, 95% CI 0.89 to 1.52) and cholangitis (aOR 1.12, 95% CI 0.72 to 1.72). Conclusions Hospitalizations for choledocholithiasis and cholangitis have increased between 2005 and 2014, reflecting a growing burden of gallstone disease. Hospital mortality between urban and rural centers is similar, however urban centers have a higher rate of procedural interventions suggesting limitations to accessing procedural interventions at rural centers.
