Estimating neoplasia detection rate (NDR) in patients with Barrett's oesophagus based on index endoscopy: a systematic review and meta-analysis.

BACKGROUND: Biopsies are obtained to confirm intestinal metaplasia and rule out prevalent dysplasia and cancer when Barrett's oesophagus (BE) is detected at index upper endoscopy (oesophagogastroduodenoscopy [EGD]). AIM: The purpose of this systematic review was to obtain summary estimates of the prevalence of high-grade dysplasia (HGD) and oesophageal adenocarcinoma (EAC) associated with BE during index EGD for chronic GERD symptoms, defined as neoplasia detection rate (NDR) which could be used as a quality measure. METHODS: An extensive search was performed within PUBMED, EMBASE and the Cochrane Library databases to identify studies in which patients underwent index endoscopy for the evaluation of the presence of BE. Two reviewers independently evaluated both the study eligibility and methodological quality and data extraction. A random-effects model (REM) based on the binomial distribution was used to calculate the pooled effects of the prevalence of BE-associated dysplasia and EAC. RESULTS: For the calculation of dysplasia and EAC prevalence rates, a total of 11 studies with 10 632 patients met the inclusion criteria including 80.4% men with a mean age of 58.7 years and average BE length of 3.5 cm. The pooled prevalence of EAC, HGD and LGD was 3%(95% CI 2 to 5, 9 studies: 396/10 539 patients), 3%(95% CI 2 to 5 [REM], 9 studies: 388/10 539 patients) and 10%(95% CI 7 to 15 [REM], 10 studies: 907/8945 patients), respectively. For NDR, that is, the pooled prevalence of HGD/EAC was 7%(95% CI 4 to 10 [REM], 10 studies: 795/10 632 patients). CONCLUSION: NDR is approximately 4% and could be used as a quality measure.

Impact of cap-assisted colonoscopy on detection of proximal colon adenomas: systematic review and meta-analysis.

BACKGROUND AND AIMS: Proximal colon adenomas can be missed during routine colonoscopy. Use of a cap or hood on the tip of the colonoscope has been shown to improve overall adenoma detection with variable rates. However, it has not been systematically evaluated for detection of proximal colon or right-sided adenomas where the cap may have maximum impact on adenoma detection rate (ADR). Our aim was to perform a systematic review and meta-analysis to evaluate the impact of cap-assisted colonoscopy (CC) on right-sided ADRs (r-ADRs) compared with standard colonoscopy (SC). METHODS: PubMed, EMBASE, SCOPUS, and Cochrane databases as well as secondary sources (bibliographic review of selected articles and major GI proceedings) were searched through October 1, 2016. Primary outcome was the pooled rate of r-ADR. Detection of flat adenoma, sessile serrated adenoma/polyp (SSA/P), and number of right-sided adenomas per patient were also assessed. Pooled odds ratio (OR) and 95% confidence intervals (CIs) were calculated using random-effect models. RESULTS: We screened 686 records and analyzed data from 4 studies (CC group, 2546 patients; SC group, 2547 patients) that met criteria for determination of r-ADRs, whereas 6 studies (CC group, 3159 patients; SC group, 3137 patients) were analyzed to estimate right-sided adenomas per patient. r-ADR was significantly higher with CC compared with SC (23% vs 17%; OR, 1.49; 95% CI, 1.08-2.05; I2 = 79%; P = .01). CC also improved detection rates of flat adenoma (OR, 2.08; 95% CI, 1.35-3.20; P < .01) and SSA/P (OR, 1.33; 95% CI, 1.01-1.74; P = .04). The total number of right-sided adenomas (CC: 1428 [60%] vs SC: 1127 [58%]) and number of right-sided adenomas per patient (CC, .71 ± .5, vs SC, .65 ± .62 [mean ± standard deviation]) were numerically higher for CC but were not statistically significant (P = .43). Approximately 17 CCs would be required to detect an additional patient with right-sided adenoma. CONCLUSIONS: Use of CC significantly improves the proximal colon ADR. In addition, flat adenoma and serrated colonic lesion detection rates are also significantly higher as compared with SC.

Endoscopic sphincterotomy vs papillary large balloon dilation vs combination modalities for large common bile duct stones: a network meta-analysis.

Background and study aims The optimal technique for removal of large common bile duct (CBD) stones (≥ 10 mm) during endoscopic retrograde cholangiopancreatography (ERCP) remains unclear. We aimed to perform a comparative analysis between different endoscopic techniques. Methods Adhering to PRISMA guidelines, a stringent search of the following databases through January 12, 2021, were undertaken: PubMed/Medline, Embase, Web of Science, and Cochrane. Randomized controlled trials comparing the following endoscopic techniques were included: (1) Endoscopic sphincterotomy (EST); (2) Endoscopic papillary large balloon dilation (EPLBD); and (3) EST plus large balloon dilation (ESLBD). Stone clearance rate (SCR) on index ERCP was the primary outcome/endpoint. Need for mechanical lithotripsy (ML) and adverse events were also evaluated as secondary endpoint. Random effects model and frequentist approach were used for statistical analysis. Results A total of 16 studies with 2545 patients (1009 in EST group, 588 in EPLBD group, and 948 patients in ESLBD group) were included. The SCR was significantly higher in ESLBD compared to EST risk ratio [RR]: 1.11, [confidence interval] CI: 1.00-1.24). Lower need for ML was noted for ESLBD (RR: 0.48, CI: 0.31-0.74) and EPLBD (RR: 0.58, CI: 0.34-0.98) compared to EST. All other outcomes including bleeding, perforation, post-ERCP pancreatitis, stone recurrence, cholecystitis, cholangitis, and mortality did not show significant difference between the three groups. Based on network ranking, ESLBD was superior in terms of SCR as well as lower need for ML and adverse events (AEs). Conclusions Based on network meta-analysis, ESLBD seems to be superior with higher SCR and lower need for ML and AEs for large CBD stones.

Does i-scan improve adenoma detection rate compared to high-definition colonoscopy? A systematic review and meta-analysis.

Background and study aims Recent studies evaluated the impact of i-scan in improving the adenoma detection rate (ADR) compared to high-definition (HD) colonoscopy. We aimed to systematically review and analyze the impact of this technique. Methods A thorough search of the following databases was undertaken: PubMed/Medline, EMBASE, Cochrane and Web of Science. Full-text RCTs and cohort studies directly comparing i-scan and HD colonoscopy were deemed eligible for inclusion. Dichotomous outcomes were pooled and compared using random effects model and DerSimonian-Laird approach. For each outcome, relative risk (RR), 95 % confidence interval (CI), and P value was generated. P  < 0.05 was considered statistically significant. Results A total of five studies with six arms were included in this analysis. A total of 2620 patients (mean age 58.6 ±â€Š7.2 years and female proportion 44.8 %) completed the study and were included in our analysis. ADR was significantly higher with any i-scan (RR: 1.20, [CI: 1.06-1.34], P  = 0.003) compared to HD colonoscopy. Subgroup analysis demonstrated that ADR was significantly higher using i-scan with surface and contrast enhancement only (RR: 1.25, [CI: 1.07-1.47], P  = 0.004). Conclusions i-scan has the potential to increase ADR using the surface and contrast enhancement method. Future studies evaluating other outcomes of interest such as proximal adenomas and serrated lesions are warranted.

Outcomes of SARS-CoV-2 infection in patients with celiac disease: a multicenter research network study.

Background: Celiac disease (CD) is associated with an increased risk for respiratory infections and severe outcomes. No data have been reported in the scientific literature regarding the outcomes of COVID-19 in this population. The aim of this study was to report matched clinical outcomes in a large cohort of 930 patients with COVID-19 in the setting of known CD. Methods: Analysis of a multicenter research network TriNETX was performed, including COVID-19 patients aged more than 16 years. Outcomes of COVID-19-positive patients with concurrent CD were compared with a propensity-matched cohort of patients without CD. Results: A total of 341,499 patients with SARS-CoV-2 infection were identified on the research network: 930 (0.27%) with CD and 340,569 (99.73%) without CD. In the 30- and 60-day periods post SARS-CoV-2 infection, 12 (1.29%) and 13 (1.40%) deaths, respectively, were reported in the CD group. Fewer patients in the CD group reached the composite outcome of either mechanical ventilation or mortality at 60 days (risk ratio 0.58, 95% confidence interval 0.36-0.95). After propensity matching, no difference in clinical outcomes was observed. Conclusion: Our data suggest that patients with CD are not at increased risk of COVID-19-related morbidity or mortality.

Endoscopic Cyst Esophagostomy Using a Lumen-Apposing Stent for a Large Mediastinal Pancreatic Pseudocyst Compressing the Left Atrium.

Pancreatic pseudocysts and peripancreatic fluid collections extending into the mediastinum are unusual. Endoscopically, intra-abdominal pseudocysts can be drained transmurally through the stomach or duodenum depending on the location. An endoscopic ultrasound-guided esophageal approach for mediastinal pseudocysts has not been reported commonly in the literature. We report a rare case of a large mediastinal pseudocyst that was drained through the distal esophagus with eventual complete resolution of symptoms and pseudocyst.

Pseudoephedrine Induced Ischemic Colitis: A Case Report and Review of Literature.

Ischemic colitis due to medications is common, and a number of cases have been described with pseudoephedrine as the culprit agent. We present here an interesting case of a healthy female with no risk factors who developed pseudoephedrine induced ischemic colitis. This case serves to remind the healthcare providers about the utmost importance of obtaining a comprehensive history to aid with the diagnosis.

Pediatric hospitalizations for inflammatory bowel disease based on annual case volume: results from the Kids' Inpatient Database 2012.

To study differences related to pediatric inflammatory bowel disease (IBD) care among hospitals that were stratified based on annual case volume. This is a cross-sectional study using data from the United States Healthcare Cost and Utilization Project Kids' Inpatient Database (KID). IBD-related hospitalizations were identified using International Classification of Diseases-9-Clinical Modification codes. Hospital volume was divided into low or high by assigning cut-off values of 1-20 and >20 annual IBD hospitalizations. We assessed a total of 8647 pediatric IBD discharges during 2012 from 660 hospitals in the USA. 107 of these hospitals were classified as high-volume centers (HVCs) for pediatric IBD care and 553 low-volume centers (LVCs). HVCs were more likely to be associated with an academic teaching status compared to LVCs (97.1% vs 67.6%, p<0.001). The incidence of transfer of medical care from LVCs to other hospitals was 5.5% but only 0.7% for HVCs (p<0.001). The median number of procedures (medical and surgical) performed on children admitted with IBD was higher at HVCs (2 vs 1, p<0.001). IBD admissions at HVCs were more likely to undergo surgical procedures compared to LVCs (17% vs 10%, p<0.001). The incidence of postoperative complications was not significantly different. There were significantly greater hospital costs (median US$11,000 vs US$6,000, p<0.001) and lengths of stay (median 5 days vs 4 days, p<0.001) associated with HVCs compared to LVCs. Pediatric admissions to HVCs for IBD undergo a greater number of medical and surgical procedures and are associated with higher costs and lengthier hospital stays.
