BACKGROUND Several studies have examined the efficacy of gastric peroral endoscopic myotomy (G-POEM) for gastroparesis. AIM To evaluate the mid-term efficacy of G-POEM by meta-analysis of studies with a minimum 1 year of follow-up. METHODS We reviewed several databases from inception to 10 June 2021 to identify studies that evaluated the efficacy of G-POEM in refractory gastroparesis, and had at least 1 year of follow-up. Our outcomes of interest were clinical success at 1 year, adverse events, difference in mean pre- and 1 year post-procedure Gastroparesis Cardinal Symptom Index (GCSI) score, and difference in mean pre- and post-procedure EndoFLIP measurements. We analysed data using a random-effects model and assessed heterogeneity by I2 statistic. RESULTS We included 10 studies comprising 482 patients. Pooled rates (95% CI) of clinical success at 1 year and adverse events were 61% (49%, 71%) and 8% (6%, 11%), respectively. Mean GCSI at 1 year post-procedure was significantly lower than pre-procedure; mean difference (MD) (95% CI) -1.4 (-1.9, -0.9). Mean post-procedure distensibility index was significantly higher than pre-procedure in the clinical success group at 40 and 50 mL volume distension; standardised mean difference (95% CI) 0.82 (0.07, 1.64) and 0.91 (0.32, 1.49), respectively. In the clinical failure group, there was no significant difference between mean pre- and post-procedure EndoFLIP measurements. CONCLUSIONS G-POEM is associated with modest clinical success at 1 year. Additional studies with longer follow-up are required to evaluate its longer-term efficacy.

Lower gastrointestinal bleeding (LGIB) is one of the most common indications for hospital admission. The current standard of care for patients admitted with LGIB includes colonoscopy. The aims of this study are to define the rate of readmission in patients with LGIB and to determine whether early colonoscopy within the first 24 h after admission impacts the rate of readmission in these patients. We performed a retrospective cohort study on data obtained from the Nationwide Readmission Database and identified patients admitted with lower GI bleed using ICD-10 codes. The primary outcome was 30-day all-cause readmission, and one of our secondary outcomes was the impact of early colonoscopy on 30-day readmission. We analyzed data from 35,790,513 patients who were admitted for LGIB in 2017. A total of 16.4% of these patients were readmitted within 30 days of discharge, with diverticular bleeding most common diagnosis for readmission. Overall, in-hospital mortality was 1.18% for index admission and 4.44% for readmission. Early colonoscopy did not impact the rate of readmission within 30 days of discharge. LGIB remains a commonly encountered in clinical practice with a high readmission rate. Mortality is significantly higher during readmission compared to index admission. Early colonoscopy did not impact the 30-day readmission rate.

Studies evaluating the role of endoscopic submucosal dissection (ESD) in the management of superficial pharyngeal cancers have reported promising results. This meta-analysis evaluates the efficacy and safety of ESD in the management of superficial pharyngeal cancers. We reviewed several databases from inception to September 03, 2020, to identify studies evaluating the efficacy and safety of ESD in the management of superficial pharyngeal cancers. Our outcomes of interest were en bloc resection rate, complete resection rate, adverse events, and rates of local recurrence. Pooled rates with 95% confidence intervals (CI) for all outcomes were calculated using random-effect model. Heterogeneity was assessed by I2 statistic. We assessed publication bias by using funnel plots and Egger’s test. We conducted meta-regression analysis to explore heterogeneity in analyses. Ten studies were included in analyses. All studies were from Asia. Pooled rates (95% CI) for en bloc resection and complete resection were 94% (87%, 97%) and 72% (62%, 80%), respectively. The pooled rates (95% CI) for adverse events and local recurrence were 10% (5%, 17%) and 1.9% (0.9%, 4%), respectively. Most of the analyses were limited by substantial heterogeneity. On meta-regression analysis, the heterogeneity was explained by size of tumor and histology. Funnel plots and Egger’s test showed no evidence of publication bias. This meta-analysis including studies from Asian countries demonstrated that ESD is an efficacious and safe option in the management of superficial pharyngeal cancers. More studies and studies from Western countries are needed to further validate these findings.

Despite being the most common healthcare-related infection in the US, nationwide data on readmission, healthcare consumption, and mortality in Clostridioides difficile infection (CDI) remain limited. We examined these outcomes in a US-based cohort of patients with CDI. We queried the 2017 Nationwide Readmission Database using ICD-10-CM codes to identify all adult patients admitted with a principal diagnosis of CDI. Primary outcomes were 30- and 90-day readmission rates. Secondary outcomes included mortality rates and healthcare consumption. Of the 83,865 patients discharged from an index hospitalization for CDI, 22.37% were readmitted within 30 days, and an additional 15.01% were readmitted within 90 days. Recurrent CDI was responsible for more than 30% of readmissions at both 30 and 90 days. Compared to the index hospitalization, readmissions were characterized by higher mortality (1.41% index vs. 4.86% 30-day vs. 4.40% 90-day) and increased hospital length of stay and charges. Medicaid insurance (HR 1.16), cirrhosis (HR 1.31), Type 1 diabetes mellitus (HR 1.38), and end-stage renal disease (HR 1.36) were independently associated with 30-day readmission (all p

BACKGROUND AND STUDY AIM Ulcerative colitis (UC) is a chronic relapsing and remitting disease requiring frequent hospitalization. Biologics have become the recommended initial therapy for Biologics in patients with moderate to severe UC. Our aim was to estimate the changes in Nationwide Healthcare utilization and assess predictive factors of 30-day readmission, morbidity and mortality of UC. METHODS This is a retrospective observational study analyzing the Nationwide Readmission database from 2016 to 2017 using ICD-10 codes. The primary outcomes of the study were to assess the predictors of 30-day readmission in patients with UC. RESULTS Of the 54 138 adult patients with a primary diagnosis of UC, 13.2% were readmitted within 30 days of index hospitalization. The mortality rate (1.4 vs. 0.3%, P < 0.01), length of stay (7 vs. 4.9 days, P < 0.01) and hospital cost ($62 552 vs. $46 971, P < 0.01) were higher on readmission as compared to index hospitalization. We identified multiple patient-related factors (age

Variceal upper gastrointestinal bleeding (VUGIB) is a common and potentially lethal complication of cirrhosis. Population-based data regarding hospital readmission and other outcomes in VUGIB are limited. In a large United States database of patients with VUGIB, we evaluated readmission rates, mortality rates, healthcare resource consumption, and identified predictors of readmission. The 2017 Nationwide Readmission Database using ICD-10 codes was used to identify all adult patients admitted for VUGIB. Primary outcomes were 30- and 90-day readmission rates. Secondary outcomes included mortality, healthcare resource consumption, and predictors of readmission. Multivariate regression analysis was used to adjust for potential confounders. In 2017, there were 26,498 patients with VUGIB discharged from their index hospitalization, and 24.7% were readmitted (all-cause) within 30-days and 41.5% within 90-days. Recurrent VUGIB accounted for 26.7% and 28.9% of 30- and 90-day readmissions, respectively. Compared to index admissions, 30-day readmissions were associated with higher mortality (4.3% vs. 6.4%, p

Transient elastography (TE) provides accurate quantification of liver fibrosis. Its usefulness could be significantly amplified in terms of predicting liver-associated clinical events (LACE). Our aim was to create a model that accurately predicts LACE by combining the information provided by TE with other variables in patients with chronic liver disease (CLD). We retrospectively reviewed the electronic medical records of patients who underwent liver elastography, at John H. Stroger Hospital in Cook County, Chicago, IL. The incidences of LACE were documented including decompensation of CLD, new hepatocellular carcinoma, and liver-associated mortality. Significant predicting factors were identified through a forward stepwise Cox regression model. We used the beta-coefficients of these risk factors to construct the Cook Score for prediction of LACE. Receiver-operating characteristic (ROC) curves were plotted for Cook Score to evaluate its efficiency in prediction, in comparison with MELD-Na Score and FIB-4 Score. A total of 3097 patients underwent liver elastography at our institution. Eighty-eight LACE were identified. Age (hazard ratio (HR) 1.04, p = 0.002), aspartate aminotransferase to alanine aminotransferase ratio (HR 2.61, p

Esophageal diverticula can cause significant symptoms and affect the quality of life. There has been recent interest in the use of peroral endoscopic myotomy in the management of esophageal diverticula (D-POEM). In this meta-analysis, we have evaluated the efficacy and safety of D-POEM in the management of esophageal diverticula. Several databases were reviewed from inception to 6/19/2020 to identify the studies evaluating the feasibility, efficacy and safety of D-POEM in the management of esophageal diverticula. Our outcomes of interest were technical success, adverse events and difference in mean pre- and post-procedure symptom score. We performed subgroup analysis including patients with Zenker's diverticulum who underwent POEM (Z-POEM). Pooled rates with 95% confidence intervals (CI) for all outcomes were calculated using random effect model. We calculated standard mean difference (SMD) with 95% CI to compare mean pre- and post-procedure symptom score. We included 7 studies with 233 patients. For D-POEM, pooled rates (95% CI) for technical success and adverse events were 95% (91%, 97%) and 6% (3%, 10%) respectively. For Z-POEM, pooled rates (95% CI) for technical success and adverse events were 95% (90%, 97%) and 6% (3%, 10%) respectively. Mean post-procedure symptom score for all patients who underwent D-POEM was significantly lower compared to mean pre-procedure symptom score, SMD (95% CI) 2.17 (1.51, 2.83). This meta-analysis demonstrated that D-POEM is a safe and feasible option for patients with symptomatic esophageal diverticula.

BACKGROUND AND STUDY AIMS The utility of water-aided techniques (WT): water exchange (WE) and water immersion (WI) have been studied extensively in the literature for improving colonoscopy outcome metrics such as adenoma detection rate. Serrated polyps owing to their location and appearance have a high miss rate. The authors performed a systematic review and meta-analysis of studies comparing WT with the standard gas-assisted (GA) method to determine if there was any impact on serrated polyp detection rate (SPDR) and sessile serrated polyp detection rate. METHODS The following databases were queried for this systematic review: Medline, EMBASE, Cochrane Library, CINAHL, and Web of Sciences. The authors only included randomized controlled trials (RCTs). The primary outcome was SPDR and secondary outcomes were sessile serrated polyp detection rate and cecal intubation rate. Risk ratios (RRs) were calculated for each outcome. A P-value

Background and aims: Anti-neoplastic immunotherapy has revolutionized cancer management; however, its safety profile with respect to liver-related injury remains largely unexplored. Herein, we analyzed a United States national database to determine the incidence, mortality, and predictors of hepatotoxicity in the setting of anti-neoplastic immunotherapy. Methods: This was a nationwide retrospective study of hospital encounters from 2011 to 2014 using the National Inpatient Sample (NIS) database. We utilized the International Classification of Diseases, Ninth Revision (ICD-9) coding system to identify all adult patients who underwent anti-neoplastic immunotherapy during hospitalization. The primary outcome was the incidence of hepatotoxicity during the same hospitalization. Secondary outcomes included in-hospital mortality as well as socioeconomic and ethno-racial predictors of hepatotoxicity. Analyses were performed using IBM SPSS Statistics 23.0. Results: The sample included 3002 patients who underwent inpatient anti-neoplastic immunotherapy. The incidence of hepatotoxicity was 10.1%, which was significantly higher as compared to a matched inpatient population (adjusted odds ratio (aOR) 4.93, 95% confidence interval (CI): 3.80–6.40, P = 0.001). No significant mortality difference was seen in those that developed hepatotoxicity compared to those who did not (aOR 0.47, 95% CI: 0.03–8.03, P = 0.612). Age under 60 (aOR 1.56, 95% CI: 1.23–1.78, P = 0.050) and white race (aOR 1.85, 95% CI: 1.35–2.04, P

BACKGROUND AND AIMS Empiric esophageal dilation is frequently performed for non-obstructive dysphagia. Studies evaluating its efficacy have reported conflicting results. In this meta-analysis, we have evaluated the efficacy of esophageal dilation in the management of non-obstructive dysphagia. METHODS We reviewed several databases from inception to 26 May 2021 to identify randomized controlled trials (RCTs) and observational studies that evaluated the role of empiric esophageal dilation for non-obstructive dysphagia. Our outcomes of interest were clinical success (improvement in dysphagia after dilation) and difference in post-operative dysphagia score between groups. For categorical variables, we calculated pooled odds ratios (OR) with 95% confidence intervals (CI); for continuous variables, we calculated standardized mean difference (SMD) with 95% CI. Data were analyzed using a random effects model. We used GRADE framework to ascertain the quality of evidence. RESULTS We included 4 studies (3 RCTs and one observational) with 243 patients; there were 133 treated with empiric dilation and 110 controls. We found no significant difference in clinical success (OR (95% CI) 1.91 (0.89, 4.08)) or post-procedure dysphagia score between groups (SMD (95% CI) 0.38 (-0.37, 1.14)). Our findings remained consistent on subgroup analysis including RCTs only. Quality of evidence ranged from low to very low based on GRADE framework. CONCLUSIONS Our meta-analysis does not support the use of empiric esophageal dilation in patients with non-obstructive dysphagia. More studies are required to confirm these findings.

COVID-19 has become a pandemic since its emergence in Wuhan, China. The disease process was initially defined by presence of respiratory symptoms; however, it is now well studied and shown in evidence that this is a multisystem process. Involvement of gastrointestinal (GI) system has been identified, and GI symptoms can be the only presenting symptoms in some patients. Hence, it is important to identify and understand the GI symptoms associated with COVID-19 for appropriate care of patient. We conducted a systematic review and metaanalysis to identify the GI symptoms of COVID-19 and identify association of diarrhea with severity of COVID-19. We performed extensive search of Medline and Embase from December 2019 to May 2020 to identify articles reporting GI symptoms in COVID-19 patients. The primary outcome was prevalence of GI symptoms in COVID-19 patients, and secondary outcome was the association of diarrhea with disease severity. A total of 38 studies with 8407 patients were included. Of the total patients, 15.47% patients had at least one GI symptom. The pooled prevalence of nausea/vomiting was 7.53% and diarrhea was 11.52%. On metaanalysis, patients with diarrhea as one of the presenting symptoms were more likely to have severe disease (OR 1.63, 95% CI: 1.11–3.38, p = 0.01). Our systematic review and metaanalysis demonstrated that GI symptoms are common in COVID-19. Presence of diarrhea as a presenting symptom is associated with increased disease severity and likely worse prognosis. Early recognition of patients is needed for prompt management of this at-risk population.

Background Patients with cirrhosis are at increased risk of Clostridioides difficile infection (CDI). We analyzed outcomes and healthcare utilization in hospitalized cirrhotic patients with CDI. Methods The Nationwide Inpatient Sample from 2016-2017 identified 8245 hospitalized patients with a concurrent diagnosis of cirrhosis and CDI. Our primary outcome was in-hospital all-cause mortality. Secondary outcomes were length of stay (LOS), hospitalization charges and costs, shock, sepsis, acute kidney injury (AKI), intensive care unit (ICU) admission, and home discharge. Results There was no significant difference in all-cause in-hospital mortality between patients with cirrhosis compared to patients without cirrhosis (adjusted odds ratio [aOR] 1.31, 95% confidence interval [CI] 0.89-1.93; P=0.16). Patients with cirrhosis had a slightly but statistically significantly longer mean LOS (+0.57 days, P=0.001). The adjusted difference in mean hospitalization charges was greater in patients with cirrhosis ($+4094, 95%CI $1080-7108; P=0.008), as was the mean hospitalization cost ($+1349, 95%CI $600-2098; P

Studies evaluating the role of tranexamic acid in acute upper GI bleeding (UGIB) have reported conflicting results. In this systematic review, we have evaluated the efficacy and safety of tranexamic acid in UGIB.We searched several databases from inception to June 6, 2020 to identify randomised controlled trials (RCTs) that compared tranexamic acid and placebo in UGIB. Our outcomes of interest were mortality, rebleeding, all thromboembolic events, venous thromboembolic events, need for transfusion, endoscopic intervention and surgery. Pooled risk ratios (RR) with 95% confidence intervals (CI) were calculated using fixed effect model. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework to assess the certainty of evidence.We included 12 RCTs comprising 14,100 patients. We found no significant difference in mortality, pooled RR (95% CI) 0.87 (0.74-1.01), rebleeding, pooled RR (95% CI) 0.90 (0.79-1.02), need for surgery, pooled RR (95% CI) 0.86 (0.73-1.02), need for transfusion, pooled RR (95% CI) 1.00 (0.99-1.01) or thromboembolic events, RR (95% CI) 1.16 (0.87-1.56) between treatments. We found an increased risk of venous thromboembolic events with tranexamic acid, pooled RR (95% CI) 1.94 (1.23-3.05). Certainty of evidence based on the GRADE framework for the different outcomes ranged from low to very low.Tranexamic acid does not improve outcomes in UGIB and may increase the risk of venous thromboembolic events.

Background and Aims Studies evaluating the role of routine second-look endoscopy in patients with acute upper GI bleed because of peptic ulcer disease (PUD) have reported conflicting results. This meta-analysis evaluates the usefulness of routine second-look endoscopy in these patients. Methods We reviewed several databases from inception to September 15, 2020 to identify randomized controlled trials (RCTs) that compared routine second-look endoscopy with no planned second-look endoscopy in patients with acute upper GI bleed because of PUD. Our outcomes of interest were recurrent bleeding, mortality, need for surgery, and mean number of units of blood transfused. For categorical variables, we calculated pooled risk ratios (RRs) with 95% confidence intervals (CIs); for continuous variables, we calculated standardized mean difference with 95% CIs. Data were analyzed using a random effects model. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework to ascertain the quality of evidence. Results We included 9 RTCs comprising 1452 patients; 726 patients underwent planned/routine second-look endoscopy and 726 did not. We found no significant difference in recurrent bleeding (RR, .79; 95% CI, .51-1.23), need for surgery (RR, .58; 95% CI, .29-1.15), mortality (RR, .69; 95% CI, .33-1.45), or mean number of units of blood transfused (standardized mean difference, –.06; 95% CI, –.19 to .07). Quality of evidence ranged from low to moderate based on the GRADE framework. Conclusions Single endoscopy with complete endoscopic hemostasis is not inferior to routine second-look endoscopy in reducing the risk of recurrent bleeding, mortality, or need for surgery in patients with acute upper GI bleed because of PUD.

The efficacy of tocilizumab (TOC), monoclonal antibody against interleukin-6 (IL-6) receptor, in patients with coronavirus disease-2019 (COVID-19) patients has led to conflicting results. We performed a systematic review and meta-analysis to compare the efficacy of addition of TOC to standard of care (SOC) versus SOC in patients with COVID-19. We performed a comprehensive literature search of PubMed, Embase, Web of Science, WHO COVID, LitCOVID, and Cochrane databases. Pooled outcomes (overall mortality, need for mechanical ventilation, intensive care unit admission, and secondary infections) were compared using DerSimonian-Laird/Random-effects approach. Risk difference (RD), confidence interval (CI), and p values were generated. A total of 23 studies with 6279 patients (1897 in TOC and 4382 in SOC group, respectively) were included. The overall mortality was lower in TOC group compared to SOC group (RD: -0.06; CI: -0.12 to -0.01; p = .03). Subgroup analysis including studies with only severe cases revealed lower mortality (RD: -0.12; CI: -0.18 to -0.06; p < .01) and need for mechanical ventilation (RD: -0.11; CI: -0.19 to -0.02; p = .01) in TOC group compared to SOC group. The addition of TOC to SOC has the potential to reduce mortality and need for mechanical ventilation in patients with severe COVID-19. Randomized controlled trials are needed to validate this.

Background Heller myotomy (HM) is an established treatment for achalasia but can fail in up to 10-20% of patients. Peroral endoscopic myotomy (POEM) may be an appropriate treatment for patients with failed HM. Methods We searched several databases to identify non-comparative studies evaluating the efficacy and/or safety of POEM after failed HM and comparative studies comparing the efficacy and/or safety of POEM in patients with and without prior HM. Outcomes assessed included clinical success, technical success, adverse events, post-treatment gastroesophageal reflux disease (GERD), and presence of esophagitis on endoscopy. We calculated weighted pooled rates with 95% confidence intervals (CI) for all outcomes in patients undergoing POEM with prior HM. We calculated pooled odds ratios with 95%CI to compare the outcomes between patients with and without previous HM who underwent POEM. Results We included 11 observational studies with 1205 patients. Weighted pooled rates (95%CI) for overall clinical success and technical success in patients with failed HM were 87% (81-91%) and 97% (94-99%), respectively. Weighted pooled rates (95%CI) for major adverse events, new-onset GERD and presence of esophagitis on endoscopy were 5% (2-10%), 33% (26-41%), and 38% (22-58%), respectively. There were no differences in clinical success, adverse events, post-treatment GERD and esophagitis between patients with and without previous HM. Conclusions POEM is safe and effective in patients with failed HM and should be considered in patients with recurrent achalasia after HM. Outcomes of POEM are comparable in patients with and without prior HM.

Data regarding hospitalization outcomes in patients with inflammatory bowel disease (IBD) with respect to hospital teaching status are largely unknown. We aimed to investigate the impact of hospital teaching status on IBD hospitalization outcomes. In this retrospective analysis, we queried the 2016 and 2017 National Inpatient Sample (NIS) databases using the International Classification of Diseases 10th revision (ICD-10) coding system. All adult patients with a principal diagnosis of IBD were included. We stratified the IBD group into ulcerative colitis (UC), Crohn’s disease (CD), and complicated IBD. Our primary outcome was mortality. Statistical analysis was performed using STATA, version 16.0. Of the 189,950 adult patients with IBD, the majority were admitted to teaching hospitals (70.9%). There was no significant difference in mortality based upon hospital teaching status (aOR 1.18, p = 0.48); however, these patients had an increased mean length of stay (adjusted coefficient: 0.82, p

Introduction Multiple pharmacological agents have been studied in literature with antispasmodic effect during colonoscopy. Peppermint oil, with its relaxing effect on colon has demonstrated varying results. We therefore conducted a systematic review and meta-analysis of the available literature to evaluate its role during colonoscopy. Evidence acquisition Literature search of the following databases was undertaken: PubMed\Medline, Embase, Cochrane, Web of Science, and CINAHL. Outcomes that were evaluated included incidence of any spasticity, severe spasticity, and peristalsis during examination. Adenoma detection rate (ADR) was evaluated as a quality outcome metric. Risk ratios (RR), risk difference (RD) and mean difference (MD) were calculated using the DerSimonian-Laird method and random effects where applicable. Evidence synthesis Overall, six studies (with one abstract) were included in this review. Peppermint oil resulted in overall lower incidence for spasticity (RD: -0.39, P=0.02), severe spasticity (RD: -0.15, P=0.04), and peristalsis (-0.27, P≤0.001) during colonoscopy examination. An improved ADR (RR: 1.31, P=0.01) was also noted, however only two studies evaluated this effect. Conclusions Peppermint oil resulted in relaxation of colon during colonoscopy with decrease incidence of spasticity, severe spasticity, peristalsis and improved ADR. These results are encouraging however results are limited due to significant heterogeneity found in the outcomes. Larger studies with standardized dosing are needed to evaluate this effect. Furthermore, studies evaluating additional colonoscopy outcomes such as polyp detection rate, advanced adenoma detection rate, and serrated adenoma detection rate are needed.

Background The role of anticoagulation in treating non-malignant portal vein (PV) thrombosis (PVT) in patients with liver cirrhosis remains unclear. In our meta-analysis, we aimed to evaluate the efficacy and safety of anticoagulation for the treatment of non-malignant PVT in these patients. Methods We conducted a meta-analysis to estimate the effects of anticoagulation on non-malignant PVT in patients with liver cirrhosis. We assessed the rates of PV recanalization, variceal bleeding, and any bleeding. Results We included 9 observational studies which involved 474 patients. The rate of PV recanalization was significantly higher in patients who received anticoagulation compared to those who did not: 65.2% vs. 25.2%; relative risk (RR) 2.31, 95% confidence interval (CI) 1.80-2.96; P

Hepatocellular carcinoma (HCC) has tripled in incidence over the past 20 years and now ranks as the third leading cause of mortality attributed to cancer. Underlying pathophysiology is sustained hepatic inflammation which results in hepatocellular dysplasia and thus an environment prone to HCC. Considering the essential role of inflammation in the pathogenesis of HCC, we evaluated the prognostic utility of ferritin-transferrin ratio (FTR) in HCC. We retrospectively reviewed the electronic medical records of patients with HCC (diagnosed on radiographic criteria and/or biopsy) from 2000 through 2015. We collected data regarding the patient demographics, laboratory investigations at the time of HCC diagnosis and prior to the initiation of treatment. Overall survival was calculated from the time of diagnosis, cases were censored at the date of last follow-up, if date of death was not known. Kaplan-Meier curves were estimated to evaluate the prognostic significance of FTR. Receiver operating characteristics (ROC) curve was plotted for FTR to predict mortality and identify cut-off value by optimized Youden’s index. Among the 176 patients identified by initial screening, 116 patients were eventually included for analysis. Overall median survival was 11.9 months. FTR, of note, was significantly lower in alive (6.9, p

Background The differences in outcomes between acute biliary pancreatitis (ABP) and acute alcohol-induced pancreatitis (AAP) have not been well studied. We sought to examine the differences between ABP and AAP as regards to in-hospital outcomes and resource utilization, using a large nationwide database. Methods We queried the National Inpatient Sample databases 2016 and 2017 using the International Classification of Diseases, 10th revision, Clinical Modification (ICD-10-CM) coding system to identify the patients with a primary diagnosis of AAP and ABP. The primary outcome was all-cause in-hospital mortality. Secondary outcomes were hospital length of stay (LOS), hospitalization charge/cost, shock, acute kidney injury (AKI), intensive care unit (ICU) admission, and home discharge. Analysis was performed with STATA software. Results There was no significant difference in mortality between patients with AAP and ABP (0.42% vs. 0.82%, adjusted odds ratio [aOR] 0.95, 95% confidence interval [CI] 0.69-1.31; P=0.79). Patients with ABP had a significantly longer LOS (+0.48 days, P

Background and Study aims: Recent studies have compared the utility of rectal indomethacin with topical epinephrine (IE) sprayed on duodenal papilla and rectal indomethacin alone (IS) to prevent post-ERCP pancreatitis (PEP) with conflicting results. We performed a systematic review and meta-analysis to evaluate the benefit of using the combination prophylaxis as oppose to rectal indomethacin alone. Methods The following database were searched for our systematic review: PubMed\Medline, Embase, Cochrane, and Web of Science. We included both randomized controlled trials (RCTs) and cohort studies. Primary outcome was incidence of PEP and secondary outcomes were adverse events and mortality. Results A total of 3 studies (all RCTs) with 2244 patients (1132 in IS and 1112 in IE group) were included. The IE group did not demonstrate any significant benefit over IS group in preventing PEP (RR: 1.15, 95 % CI 0.62 – 2.2), mortality (RR: 0.85, 95 % CI 0.22 – 3.24) or overall adverse events (RR: 1.3, 95 % CI 0.93 – 1.7). Conclusion The combination of rectal indomethacin and topical epinephrine failed to demonstrate any benefit over indomethacin alone in preventing PEP, decreasing mortality and overall adverse events.

INTRODUCTION: Since its emergence in Wuhan, China in late 2019, COVID-19 has become a global pandemic Initially defined predominantly by respiratory symptoms, it is now well understood that COVID-19 affects multiple systems Gastrointestinal (GI) symptoms have been identified in these patients and in some patients, these are the only presenting symptoms Therefore, it is vital that we identify and understand the GI symptoms associated for prompt diagnosis and management We [200] Figure 1 Forest plot of studies with odd's ratio (OR 1 63, 95% CI: 1 11-2 38, P = 0 01) conducted a systematic review and meta-analysis to identify the GI symptoms of COVID-19 and its association with disease severity METHODS: We searched Medline and Embase from December 2019 to May 2020 to identify articles reporting GI symptoms in COVID-19 patients The primary outcome was prevalence of GI symptoms in COVID-19 patients, and secondary outcome was the association of GI symptoms with disease severity RESULTS: A total of 38 studies with 8,407 patients were included Of the total patients, 15 47% patients had at least one GI symptom The pooled prevalence of nausea/vomiting was 7 53% and diarrhea was 11 52% (Table 1) On meta-analysis, patients with diarrhea as one of the presenting symptoms were more likely to have severe disease (OR 1 63, 95% CI: 1 11-3 38, P = 0 01) as shown in Figure 1 CONCLUSION: Our systematic review and meta-analysis demonstrated that GI symptoms are common in COVID-19 patients with diarrhea and nausea/vomiting being the predominant symptoms Presence of diarrhea as a presenting symptom is associated with increased disease severity and likely worse prognosis Patients with diarrhea likely harbor increased viral load, which can potentially lead to an increased systemic response to the virus and associated respiratory complications from it Early recognition of patients is needed for prompt management of this at-risk population
