Background: Hybrid approaches combining endoscopic full-thickness resection (EFTR) with conventional techniques (endoscopic mucosal resection [EMR], endoscopic submucosal dissection [ESD]) have enabled the resection of difficult fibrotic colorectal adenomas exhibiting a "non-lifting" sign, and polyps in difficult positions. We present our cohort treated with either EMR+EFTR or ESD+EFTR as salvage hybrid endoscopic approaches for complex colorectal polyps not amenable to conventional techniques.

Methods: Retrospective analysis included technical success, histological confirmation of margin-free resection, assessment of adverse events and follow up with histological assessment. All patients underwent follow-up endoscopy at least 6 and 12 months post-resection.

Results: Fourteen patients underwent hybrid EFTR procedures (11 EMR+EFTR and 3 ESD+EFTR). Technical success was achieved in all cases where the full-thickness resection device (FTRD) was advanced to the site of the resection (100%). In 2 cases, the FTRD system could not be passed through the sigmoid colon because of severe chronic diverticulitis, subsequent fibrosis and stiffness. The mean lesion size in the EMR+EFTR group (41.7 mm; range 20-50 mm) was larger than the ESD+EFTR group (31.7 mm; range 30-35 mm). Six patients (42.9%) were histologically diagnosed with T1 carcinoma. The mean duration of hospitalization was 1.4 days. Follow-up endoscopy was available in all patients and no recurrence was observed with histological confirmation during a mean follow-up period of 15.4 months.

Conclusion: Hybrid procedures appear to be safe and effective treatments for complex colorectal lesions not amenable to EMR, ESD or EFTR alone, because of the lesion size, positive non-lifting sign, and difficult positions.

Background: Diverticular bleeding is the leading cause of lower gastrointestinal bleeding, affecting 3-5% of patients with diverticulosis. Current management protocols include resuscitation, diagnosis via direct visualization, computed tomography imaging, endoscopic interventions, angioembolization, and surgery when needed. However, predictive factors for outcomes and optimal interventions remain ambiguous.

Methods: This retrospective cohort study analyzed data from the National Inpatient Sample (NIS) database (2016-2020) to determine predictors of adverse in-hospital outcomes in diverticular bleeding patients without perforation or abscess. Demographic and clinical data were extracted, and multivariate regression models were applied. Analysis was conducted using R statistical software (version 4.1.3), with significance set at P<0.05.

Results: A total of 28,269 patients hospitalized for diverticular bleeding were identified. Age >85 years, moderate to severe Charlson Comorbidity Index, hypovolemic shock, blood transfusion requirement, and requirement for colectomy were significantly associated with greater in-hospital mortality. Factors such as late colonoscopy timing and colon resection led to longer hospital stays, while arterial embolization was predicted by older age, Black race, hypovolemic shock, and blood transfusion. Predictors of colon resection included advanced age, presence of colon cancer, and hypovolemic shock.

Conclusions: Our retrospective study identified significant predictors of in-hospital outcomes among patients with diverticular bleeding, informing risk stratification and management strategies. Further research is warranted to validate these findings and refine management algorithms for improved patient care. Integrating these insights into clinical practice may enhance outcomes and guide personalized interventions in diverticular bleeding management.

Background: The safety and technical success of endoscopic ultrasound-guided antegrade treatment (EUS-AG) compared to balloon enteroscopy-assisted endoscopic cholangiopancreatography (BE-ERCP) for choledocholithiasis in Roux-en-Y gastrectomy has not been well documented. We performed a systematic review and meta-analysis to assess the safety and efficacy of the 2 procedures.

Methods: A systematic search of multiple databases was undertaken through January 25, 2024, to identify relevant studies comparing the 2 procedures. Standard meta-analysis methods were employed using a random-effects model. For each outcome, risk-ratio (RR), 95% confidence interval (CI), and P-values were generated. P<0.05 was considered significant. Heterogeneity was assessed using the I ² statistic.

Results: Three studies with 795 patients (95 in the EUS-AG group and 700 in the BE-ERCP group) were included. The technical success rate was similar between EUS-AG and BE-ERCP (RR 1.08, 95%CI 0.84-1.38; P=0.57; I ²=56%). The overall rate of adverse effects was higher in the BE-ERCP group than in the EUS-AG group (RR 1.95, 95%CI 1.21-3.15; P=0.006; I ²=0 %). Rates of clinical success, pancreatitis, perforation, and bile peritonitis were similar between the 2 procedure techniques.

Conclusions: Our analysis showed no distinct advantage in using one technique over the other for patients with Roux-en-Y anatomy in achieving technical and clinical success. However, the incidence of adverse effects was greater in the BE-ERCP group than in the EUS-AG group.

Cirrhotic cardiomyopathy represents a syndrome of cardiac dysfunction associated with advanced liver disease. It is the result of complex pathophysiological processes that complicate the course of the disease, and is generally associated with a poor prognosis. Pathophysiologically, portal hypertension is the key factor leading to hyperdynamic circulation, via over-activation of the neurohumoral axis. Intestinal obstruction, subclinical inflammation and hepatocellular insufficiency, with defective synthesis or metabolism of several vasoactive mediators, are essential components of this process. Since it is usually unapparent at rest and only unmasked by an inadequate cardiac response to hemodynamic stress, the diagnosis of cirrhotic cardiomyopathy is challenging and demands a multimodal approach. There is currently no specific therapy, but there are prognostically effective drugs available to treat heart failure. Therefore, it is crucial to identify patients with chronic liver disease and heart failure in order to ameliorate their outcome. This article attempts to highlight the most important aspects of cirrhotic cardiomyopathy and draws attention to this condition.

Background: Stent selection in the endoscopic management of post-liver-transplant anastomotic biliary strictures remains controversial. This systematic review and meta-analysis aimed to evaluate the potential differences between available stents.

Methods: MEDLINE, Cochrane, and Scopus databases were searched until April 2023 for comparative studies evaluating stricture management using multiple plastic stents (MPS) and self-expandable metal stents (SEMS), including fully-covered (FC)- and intraductal (ID)-SEMS. The primary outcome was stricture resolution, while secondary outcomes included stricture recurrence, stent migration and adverse events. Meta-analyses were based on a random-effects model and the results were reported as odds ratios (OR) with 95% confidence intervals (CI). Subgroup analyses by type of metal stent and a cost-effectiveness analysis were also performed.

Results: Nine studies (687 patients) were finally included. Considering stricture resolution, SEMS and MPS did not differ significantly (OR 0.99, 95%CI 0.48-2.01; I ²=35%). Stricture recurrence, migration rates and adverse events were also comparable (OR 1.71, 95%CI 0.87-3.38; I ²=55%, OR 0.73, 95%CI 0.32-1.68; I ²=56%, and OR 1.47, 95%CI 0.89-2.43; I ²=24%, respectively). In the subgroup analysis, stricture resolution and recurrence rates did not differ for ID-SEMS vs. MPS or FC-SEMS vs. MPS. Migration rates were lower for ID-SEMS compared to MPS (OR 0.28, 95%CI 0.11-0.70; I ²=0%), and complication rates were higher after FC-SEMS compared to MPS (OR 1.76, 95%CI 1.06-2.93; I ²=0%). Finally, ID-SEMS were the most cost-effective approach, with the lowest incremental cost-effectiveness ratio: 3447.6 £/QALY.

Conclusion: Stent type did not affect stricture resolution and recurrence; however, ID-SEMS placement was the most cost-effective approach compared to the alternatives.

Background: The wide range of R0 resection rates (R0RR) and incomplete resection rates (IRR) observed with conventional cold snare polypectomy (CCSP) emphasizes the necessity for technique enhancement. The COLDWATER study aimed to compare underwater cold snare polypectomy (UCSP) to CCSP for 5-10-mm colorectal polyps, focusing on comprehensive histopathological evaluation, efficacy, and safety.

Methods: This was a randomized, single-blind, controlled trial comparing UCSP to CCSP for non-pedunculated colorectal polyps of size 5-10 mm. The primary outcome was to report differences in the muscularis mucosa resection ratio. The secondary outcomes focused on differences in depth of excision, R0-RR, IRR, en bloc resection rate, adverse events, and recurrence rate.

Results: The COLDWATER study found higher muscularis mucosa resection in UCSP (81.72±62.81% vs. CCSP: 72.33±22.33%, P=0.003) with comparable submucosa presence (UCSP: 16.6%, CCSP: 12.5%, P=0.25). UCSP showed better outcomes regarding IRR (3.5% vs. 8.5%, P=0.05) and en bloc resection (98% vs. 93.5%, P=0.04). In CCSP, expert endoscopists achieved higher R0RR than non-experts, while UCSP showed no significant difference in R0RR across endoscopist's experience levels.

Conclusions: UCSP achieves a more extensive excision of the muscularis mucosa compared to CCSP, even though it does not attain a deeper excision. Additionally, UCSP shows a higher en bloc resection rate, with lower rates of IRR, and emerges as a promising technique for training inexperienced endoscopists in polypectomy, given its experience-independent success in achieving R0 resection.

Background: Vascular intestinal disorder (VID) is a condition with a low incidence, but a high mortality risk. The increasing prevalence of substance abuse and metabolic syndrome among young individuals could impact the burden of VID. This study aimed to evaluate the impact of VID on young individuals.

Methods: Our study harnessed data from the Global Burden of Disease study, spanning 2000 to 2019. With this extensive dataset, we conducted a comprehensive analysis of the prevalence, mortality rates, and impact on disability-adjusted life years (DALYs) related to VID among young individuals aged 15 to 49 years.

Results: Globally, there were an estimated 32,628 cases, 3869 deaths, and 201,099 million DALYs attributed to VID in young individuals. Geographically, the regions of America had the highest burden of VID in young individuals. From 2000-2019, there was an increasing prevalence in all areas, with the most pronounced change observed in Southeast Asia (annual percentage change [APC] +2.17%, P<0.001). Over the study period, there was a more rapid increase in prevalence in males (APC +0.82%, P<0.001) than in females (APC +0.59%, P<0.001). Rates of death and DALYs declined in most regions, except for the Eastern Mediterranean region, where there was a slight increase (APC +0.85%, P<0.001 and 0.88%, P<0.001, respectively).

Conclusion: Over the past decade, the burden of VID in young individuals has been increasing, particularly in Southeast Asia and the Eastern Mediterranean region, necessitating immediate and inclusive measures to tackle the rising burden.

Background: Inflammatory bowel disease (IBD) epidemiology has changed rapidly in recent years. We aimed to provide a systematic report of the burden of IBD at a state level in the United States (US), and to study the age- and sex-specific trends of incidence, prevalence and mortality rates for the past 3 decades.

Methods: Using the Global Burden of Disease (GBD) 2019 Study Database, we examined the incidence, prevalence and mortality rate, and the disability-adjusted life-years from GBD 2019 at national and state level from 1990-2019.

Results: There was an overall decrease in incidence and prevalence rates of IBD in the US from 1990-2019, while a simultaneous increase in the overall mortality rates was identified. However, a distinct trend of increasing incidence and prevalence rates emerged starting in 2000, with incidence rates rising from 21 cases per 100,000 persons in 2000 to 23 cases per 100,000 persons in 2019. From 1990-2019, incidence and prevalence decreased in males at a higher rate than in females. However, mortality rates increased more in females than males. Incidence rates were highest in Midwestern and Eastern states, and were lowest across the northern Great Plains and Western states, with the highest incidence noted in Michigan (31 cases per 100,000 persons). California had the greatest decrease in incidence rates from 1990-2019 (-63.3%).

Conclusion: Our results concerning recent trends and geographic variations in IBD offer policymakers crucial insights for informed decision-making in policy, research, and investment, facilitating more effective strategies and allocation of resources.

Background: Hemostatic powders are used as second-line treatment in acute gastrointestinal (GI) bleeding (AGIB). Increasing evidence supports the use of TC-325 as monotherapy in specific scenarios. This prospective, multicenter study evaluated the performance of TC-325 as monotherapy for AGIB.

Methods: Eighteen centers across Europe and USA contributed to a registry between 2016 and 2022. Adults with AGIB were eligible, unless TC-325 was part of combined hemostasis. The primary endpoint was immediate hemostasis. Secondary outcomes were rebleeding and mortality. Associations with risk factors were investigated (statistical significance at P≤0.05).

Results: One hundred ninety patients were included (age 51-81 years, male: female 2:1), with peptic ulcer (n=48), upper GI malignancy (n=79), post-endoscopic treatment hemorrhage (n=37), and lower GI lesions (n=26). The primary outcome was recorded in 96.3% (95% confidence interval [CI]: 92.6-98.5) with rebleeding in 17.4% (95%CI 11.9-24.1); 9.9% (95%CI 5.8-15.6) died within 7 days, and 21.7% (95%CI 15.6-28.9) within 30 days. Regarding peptic ulcer, immediate hemostasis was achieved in 88% (95%CI 75-95), while 26% (95%CI 13-43) rebled. Higher ASA score was associated with mortality (OR 23.5, 95%CI 1.60-345; P=0.02). Immediate hemostasis was achieved in 100% of cases with malignancy and post-intervention bleeding, with rebleeding in 17% and 3.1%, respectively. Twenty-six patients received TC-325 for lower GI bleeding, and in all but one the primary outcome was achieved.

Conclusions: TC-325 monotherapy is safe and effective, especially in malignancy or post-endoscopic intervention bleeding. In patients with peptic ulcer, it could be helpful when the primary treatment is unfeasible, as bridge to definite therapy.

Background: Achalasia can cause disabling symptoms that may substantially impair the quality of life. Peroral endoscopic myotomy (POEM) has shown promising results in the management of achalasia. In this meta-analysis we have evaluated the feasibility and safety of single-session POEM with fundoplication (POEM+F) in patients with achalasia.

Methods: We reviewed several databases from inception to July 08, 2022, to identify studies evaluating the feasibility and/or safety of single-session POEM+F for patients with achalasia. Our outcomes of interest included the technical success of POEM+F, adverse events, esophagitis and wrap integrity on follow-up upper endoscopy, total procedure time, and fundoplication time. Pooled rates with 95% confidence intervals (CI) for outcomes were calculated using a random effect model. Heterogeneity was assessed using the I ² statistic.

Results: We included 4 studies with 90 patients. Pooled rates (95%CI) of technical success and adverse events were 92% (83-96%) and 5% (2-11%), respectively. Pooled rates (95%CI) of esophagitis and wrap integrity on follow-up upper endoscopy were 18% (11-30%) and 85% (43-98%) respectively. Pooled mean procedure time and fundoplication time were 113.2 (98.7-127.6) and 55.3 (43.7-66.8) min, respectively.

Conclusions: This meta-analysis demonstrates the feasibility and safety of POEM+F in patients with achalasia. More studies with long-term follow up are required to further validate these findings.
