RESUMO
OBJECTIVE: Disorders of gut-brain interaction may arise after acute gastroenteritis. Data on the influence of pathogen type on the risk of postinfection IBS (PI-IBS), as on postinfection functional dyspepsia (PI-FD), are limited. We conducted a systematic review and meta-analysis to determine prevalence of PI-IBS or PI-FD after acute gastroenteritis. DESIGN: We included observational studies recruiting ≥50 adults and reporting prevalence of IBS or FD after acute gastroenteritis with ≥3-month follow-up. A random effects model was used to estimate prevalence and ORs with 95% CIs. RESULTS: In total, 47 studies (28 170 subjects) were eligible. Overall prevalence of PI-IBS and PI-FD were 14.5% and 12.7%, respectively. IBS persisted in 39.8% of subjects in the long-term (>5 years follow-up) after diagnosis. Individuals experiencing acute gastroenteritis had a significantly higher odds of IBS (OR 4.3) and FD (OR 3.0) than non-exposed controls. PI-IBS was most associated with parasites (prevalence 30.1%), but in only two studies, followed by bacteria (18.3%) and viruses (10.7%). In available studies, Campylobacter was associated with the highest PI-IBS prevalence (20.7%) whereas Proteobacteria and SARS-CoV-2 yielded the highest odds for PI-IBS (both OR 5.4). Prevalence of PI-FD was 10.0% for SARS-CoV-2 and 13.6% for bacteria (Enterobacteriaceae 19.4%). CONCLUSION: In a large systematic review and meta-analysis, 14.5% of individuals experiencing acute gastroenteritis developed PI-IBS and 12.7% PI-FD, with greater than fourfold increased odds for IBS and threefold for FD. Proinflammatory microbes, including Proteobacteria and subcategories, and SARS-CoV-2, may be associated with the development of PI-IBS and PI-FD.

BACKGROUND AND AIMS: Limited evidence exists regarding the impact of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on upper endoscopy. Therefore, a meta-analysis was conducted to comprehensively review the available evidence on this subject. METHODS: A systematic bibliographic search was carried out until May 2024. Pooled estimates were analyzed using a random-effects model, with results presented as odds ratios (OR) and 95% confidence intervals (CI). The primary outcome assessed was the rate of retained gastric content (RGC), while secondary outcomes included rates of aborted and repeated procedures, adverse event (AE) rate, and rates of aspiration. RESULTS: This analysis included 13 studies involving a total of 84,065 patients. Patients receiving GLP-1RA therapy exhibited significantly higher rates of RGC (OR 5.56, 3.35-9.23), a trend that was consistent among patients with diabetes (OR 2.60, 2.23-3.02). Adjusted analysis, accounting for variables such as sex, age, body mass index (BMI), diabetes, and other therapies, confirmed the elevated rates of RGC in the GLP-1RA user group (aOR 4.20, 3.42-5.15). Furthermore, rates of aborted and repeated procedures were higher in the GLP-1RA user group (OR 5.13, 3.01-8.75, and OR 2.19, 1.43-3.35; respectively). However, no significant differences were found in AE and aspiration rates between the two groups (OR 4.04, 0.63-26.03, and OR 1.75, 0.64-4.77; respectively). CONCLUSION: Use of GLP-1RAs is associated with increased retention of gastric contents and more frequent aborted procedures during upper endoscopy. However, the AEs and aspiration rates do not seem different, therefore adjusting fasting time instead of routinely withholding GLP-1RAs could be reasonable in these patients.
RESUMO
INTRODUCTION: This study aims to evaluate the effectiveness of ChatGPT (Chat Generative Pretrained Transformer) in answering patients' questions about colorectal cancer (CRC) screening, with the ultimate goal of enhancing patients' awareness and adherence to national screening programs. METHODS: 15 questions on CRC screening were posed to ChatGPT4. The answers were rated by 20 gastroenterology experts and 20 non-experts in three domains (accuracy, completeness, and comprehensibility), and by 100 patients in three dichotomic domains (completeness, comprehensibility and trustability). RESULTS: According to expert rating, the mean accuracy score was 4.8±1.1 on a scale ranging from 1 to 6. Men completeness score was 2.1±0.7 and mean comprehensibility score was 2.8±0.4 on a scale ranging from 1 to 3. Overall, accuracy (4.8±1.1 vs 5.6±0.7, P<0.001) and completeness (2.1±0.7 vs 2.7±0.4, P<0.001) scores were significantly lower for expert compared to non-expert, while comprehensibility was comparable among the two groups (2.7±0.4 vs 2.8±0.3, P=0.546). Patients rated all questions as complete, comprehensible and trustable in 97 to 100% of cases. CONCLUSIONS: ChatGPT shows good performance with the potential to enhance awareness about CRC and improve screening outcomes. Generative language systems may be further improved after proper training in accordance with scientific evidence and current guidelines.
RESUMO
INTRODUCTION: Endoluminal radiofrequency ablation (RFA) is a palliative treatment for patients suffering from malignant biliary obstruction. We aimed to conduct a meta-analysis to evaluate the impact of RFA on stent patency, patient survival, and adverse events. METHODS: Major databases were searched through November 2023 for patients who underwent stenting with or without RFA for extra-hepatic malignant biliary obstruction. A random effects model was employed for analysis and results conveyed using relative risk ratio with 95% confidence interval. RESULTS: Nine RCTs involving 750 subjects (n=374 RFA plus stent vs. n=376 stent only) with malignant biliary obstruction were included. Meta-analysis revealed similar risks of stent patency at 3 months (RR = 1.01; 95% CI [0.92 - 1.11], I2=4% for RFA plus stenting vs. stent only). Meta-analysis showed improved survival at 6 months (RR = 0.84; 95% CI [0.73 - 0.96], I2=21%, P=0.01 for RFA plus stenting vs. stent only). Subgroup analysis comparing plastic vs uncovered metal stents showed that stent patency was unaffected at 3 months (RR = 1.06; 95% CI [0.91 - 1.23]; I2=17%). Subgroup analysis showed that patients with cholangiocarcinoma experienced an overall survival benefit with RFA plus stenting vs. stent only (P<0.001), however, stent patency remained unaffected (P=0.08). An increased incidence of cholecystitis was noted with RFA plus stent vs. stent only (5.1%; 95% CI [3.1% - 7.8%] vs 0.3%; 95% CI [0.01% - 1.5%], respectively). CONCLUSION: Combining endoluminal RFA and stenting may improve overall survival in patients with malignant biliary obstruction. RFA did not impact stent patency significantly.
RESUMO
OBJECTIVE: Bowel cleansing is a key element for a quality colonoscopy. Despite recent advances, not all predictors of successful cleansing are fully known. This post hoc analysis of an RCT aims to explore gender differences in bowel cleansing quality. METHODS: The "OVER" trial was a multicenter phase-4 RCT including 478 patients randomized 1:1 to receive split-dose 1L polyethylene glycol plus ascorbate (PEG+ASC) or 4L-PEG. In this post hoc analysis, multivariable logistic regression models were designed to assess predictors of cleansing success (CS) and adenoma detection rate (ADR) by gender. RESULTS: Of the 478 randomized patients, 50.2% were males and 49.8% females.Overall, CS was comparable between females and males (87.1% vs 88.4, P = 0.6), whereas CS in the right (95.7% vs 90.9, P = 0.049) and transverse colon (98.6% vs 93.9, P=0.011) was significantly higher in females.At multivariable regression analysis for CS outpatient setting (OR = 5.558) and higher withdrawal time (OR = 1.294) were independently associated with CS in females, whereas screening/surveillance indication (OR = 6.776) was independently associated with CS in males.At multivariable regression analysis for ADR, running time <5 hours (OR = 3.014) and higher withdrawal time (OR = 1.250) were independently associated with ADR in females, whereas older age (OR = 1.040) and higher withdrawal time (OR = 1.093) were independently associated with ADR in males. CONCLUSIONS: This study showed different results in bowel preparation quality and different predictors of CS and ADR by gender. These findings suggest the need for further research to explore gender-specific approaches for bowel preparation.
RESUMO
BACKGROUND: Cystic fibrosis (CF) is a multisystem disorder that leads to abnormal transport of chloride and sodium across secretory epithelia resulting in thickened, viscous secretions in the bronchi, biliary tract, pancreas, intestine, and the reproductive system. Defects in the biliary tract can predispose to stone formation requiring endoscopic retrograde cholangiopancreatography (ERCP). However, there is a paucity of data assessing ERCP outcomes in patients with CF. METHODS: We identified patients from the Healthcare Cost and Utilization Project (HCUP)-National Inpatient Sample (NIS) between the years 2016 and 2020. Our study group included patients with CF of all ages who underwent an inpatient ERCP. We used ICD10 diagnostic and procedural codes to identify patients, procedures, and complications of the procedure. RESULTS: From 2016 to 2020, a total of 860,679 inpatient ERCPs were identified. Of these procedures, 535 (0.06%) were performed in patients with CF. The mean age of patients with CF undergoing ERCP was 60.62 years, of which 48% were males and 52% were females. Patients in the CF group had a higher incidence of post-ERCP pneumothorax (0.93%) than the patients in the non-CF group (0.15%). The occurrence of other ERCP-related adverse events was similar in both groups (P>0.05). On multivariate regression analysis, patients with CF were 1.75 times more likely to develop post-ERCP infections [odds ratio (OR): 1.75; 95% CI: 1.03-2.94; P=0.035) and 7.64 times more likely to develop post-ERCP pneumothorax (OR: 7.64; 95% CI: 1.03-56.5; P=0.046) compared to patients without CF after adjusting for confounders. The groups had no significant difference in mortality, post-ERCP pancreatitis, bleeding, perforation, pneumoperitoneum, and gas embolism. There was also no significant difference in the length of stay between the study and control groups. CONCLUSIONS: ERCP is a safe procedure in patients with CF with a comparable risk of postprocedural complications and mortality to those who do not have cystic fibrosis. However, patients with CF may experience a higher risk of post-ERCP infections and post-ERCP pneumothorax. Further studies are needed to prospectively evaluate outcomes of ERCP in patients with CF and to determine methods of mitigating adverse events.
RESUMO
BACKGROUND: There is increasing evidence that cold endoscopic mucosal resection (c-EMR) can effectively treat large colorectal polyps. We aim to appraise the current literature and evaluate outcomes following c-EMR for nonpedunculated colonic polyps ≥20 mm. METHODS: Major databases were searched. Primary outcomes included recurrence rate and adverse events. Meta-analysis was performed using a random-effects model. RESULTS: Nine articles were included in the final analysis, which included 817 patients and 1077 colorectal polyps. Average polyp size was 28.8 (±5.1) mm. The pooled recurrence rate of polyps of any histology at 4 to 6 months was 21.0% (95% CI: 9.0%-32.0%, P <0.001, I2 =97.3, P <0.001). Subgroup analysis showed that recurrence was 10% for proximal lesions (95% CI: 0.0%-20.0%, P =0.054, I2 =93.7%, P =0.054) and 9% for distal lesions (95% CI: 2.0%-21.0%, P =0.114, I2 =95.8%, P =0.114). Furthermore, subgroup analysis showed that recurrence was 12% for adenoma (95% CI: 4.0%-19.0%, P =0.003, I2 =98.0%, P =0.003), and 3% for sessile serrated polyps (95% CI: 1.0%-5.0%, P =0.002, I2 =34.4%, P =0.002). Post-polypectomy bleeding occurred in 1% (n=8/817) of patients, whereas abdominal pain occurred in 0.2% (n=2/817) of patients. CONCLUSIONS: C-EMR for nonpedunculated colorectal polyps ≥20 mm shows an excellent safety profile with a very low rate of delayed bleeding as well as significantly less recurrence for sessile serrated polyps than adenomas.

Clostridioides difficile infection (CDI) is one of the most common healthcare-associated infections and one of the leading causes of morbidity and mortality in hospitalized patients in the world. Although several antibiotics effectively treat CDI, some individuals may not respond to these drugs and may be cured by transplanting stool from healthy donors. FMT has demonstrated extraordinary cure rates for the cure of CDI recurrences.Moreover, FMT has also been investigated in other disorders associated with the alteration of gut microbiota, such as inflammatory bowel disease (IBD), where the alterations of the gut microbiota ecology have been theorized to play a causative role. Although FMT is currently not recommended to cure IBD patients in clinical practice, several studies have been recently carried out with the ultimate goal to search new therapeutic options to patients.This review summarizes data on the use of FMT for the treatment of both CDI and IBD, with a special attention to highlight studies conducted in European countries.

Hepatitis E virus (HEV) infection is typically a self-limiting, acute illness that spreads through the gastrointestinal tract but replicates in the liver. However, chronic infections are possible in immunocompromised individuals. The HEV virion has two shapes: exosome-like membrane-associated quasi-enveloped virions (eHEV) found in circulating blood or in the supernatant of infected cell cultures and non-enveloped virions ("naked") found in infected hosts' feces and bile to mediate inter-host transmission. Although HEV is mainly spread via enteric routes, it is unclear how it penetrates the gut wall to reach the portal bloodstream. Both virion types are infectious, but they infect cells in different ways. To develop personalized treatment/prevention strategies and reduce HEV impact on public health, it is necessary to decipher the entry mechanism for both virion types using robust cell culture and animal models. The contemporary knowledge of the cell entry mechanism for these two HEV virions as possible therapeutic target candidates is summarized in this narrative review.

BACKGROUND: Patients with inflammatory bowel diseases (IBD) require proactive monitoring both during the active phase to evaluate therapeutic response and during the remission phase to evaluate relapse or colorectal cancer surveillance. However, monitoring may vary between patients with ulcerative colitis (UC) and Crohn's disease (CD), with distinct tools and intervals. METHODS: This narrative review aims to focus on modern approaches to IBD monitoring, considering international guidelines and expert consensus. RESULTS: The most recent European diagnostic guidelines advocate a combination of clinical, laboratory, endoscopic, and radiological parameters to evaluate the disease course of patients with IBD. Unfortunately, the conventional symptom-based therapeutic approach does not improve long-term outcomes and there is no single ideal biomarker available. Endoscopy plays a key role in evaluating response to therapy as well as monitoring disease activity. Recently, bedside intestinal ultrasound (IUS) has gained increasing interest and diffusion as it appears to offer several advantages including the monitoring of therapeutic response. CONCLUSION: In light of growing clinical advances, we present a schematic evidence-based monitoring algorithm that can be easily applied in clinical practice which combines all major monitoring modalities, including noninvasive tools such as IUS and video-capsule endoscopy.
RESUMO
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.
RESUMO
OBJECTIVES: Endoscopic submucosal dissection (ESD) is a minimally invasive technique for the resection of superficial gastrointestinal lesions, providing high rates of 'en bloc' and R0 resection. East-West differences in ESD quality indicators have been reported. This study aims to assess feasibility, effectiveness, and safety of ESD for the treatment of superficial gastrointestinal (GI) lesions in a Western cohort. METHODS: Consecutive patients undergoing ESD at one Italian endoscopic referral center from September 2018 to March 2020 were included in this prospective study. Primary outcomes were technical success, R0 resection rate, curative resection rate, and adverse events (AEs). RESULTS: In total 111 patients (111 lesions) undergoing ESD were included. Anatomic site of the lesions was rectum in 56.8%, colon in 13.5%, stomach in 24.3%, and esophagus in 5.4% of cases, respectively. For upper GI procedures, technical success was 100%, and R0 and curative resection rates were 84.8% and 78.8%, respectively. For colorectal procedures, technical success was 98.7%, R0 and curative resection rates were 88.5% and 84.6%, respectively. Major AEs were reported in 12 cases (10.8%). CONCLUSION: The introduction of ESD in a Tertiary Center is feasible, effective, and safe, and should be taken into consideration for the treatment of superficial GI lesions requiring 'en bloc' resection.
RESUMO
In this editorial, we explore the challenges of managing noncurative resections in early gastric cancer after endoscopic submucosal dissection (ESD), starting from the consideration recently made by Zhu et al. Specifically, we evaluate the management of eCura C1 lesions, where decisions regarding further interventions are pivotal yet contentious. Collaboration among endoscopists, surgeons, and pathologists is underscored to refine risk assessment and personalize therapeutic management. Recent advancements in ESD techniques and interdisciplinary collaboration offer opportunities for outcome optimization in managing eCura C1 lesions. Moreover, despite needing further clinical validation, molecular biomarkers have emerged as promising tools for enhancing prognostication. This manuscript highlights the ongoing research attempts to define treatment paradigms effectively and evaluates the potential of emerging options, ultimately aiming to improve patient care and outcomes in this complex clinical scenario.
RESUMO
Colorectal cancer (CRC) has the highest mortality rate among men and is the second highest among women under fifty, with incidence and mortality rates rising in younger populations. Studies indicate that up to one-third of patients diagnosed before fifty have a family history or genetic factors, highlighting the need for earlier screening. Contrariwise, diagnosis in healthy subjects through screening strategies enables early-stage detection of the tumor and better clinical outcomes. In recent years, mortality rates of CRC in Western countries have been on a steady decline, which is largely attributed to widespread screening programs and advancements in treatment modalities. Indeed, early detection through screening significantly improves prognosis, with stark differences in survival rates between localized and metastatic disease. This article aims to provide a comprehensive review of the existing literature, delving into the performance and efficacy of various CRC screening strategies. It navigates through available screening tools, evaluating their efficacy and cost-effectiveness. The discussion extends to delineating target populations for screening, emphasizing the importance of tailored approaches for individuals at heightened risk.
RESUMO
Background: Endoscopic submucosal dissection (ESD) is an advanced technique that can become more challenging in the presence of submucosal fibrosis. Predicting the grade of fibrosis is important in order to identify technically difficult ESD. Aims and Methods: Our study aimed to derive and validate a prediction model to determine the preoperative degree of submucosal fibrosis in colorectal tumours undergoing ESD. A predictive model was developed to derive the probability of an increasing submucosal fibrosis in the derivation cohort and then externally validated. Results: 309 patients (age: 68 ± 10.9 years) underwent colorectal ESD between January 2016 and June 2020. F0, F1, and F2 fibroses were reported in 196 (63.4%), 70 (22.6%), and 43 (13.9%) cases, respectively. R0 resection was found in 266 (87%) lesions. At multivariable analysis in the derivation cohort, lesion morphology (OR = 0.37 and CI = 0.14-0.97 for LST-NG vs. 0-Is; OR = 0.29 and CI = 0.1-0.87 for the LST mixed type vs. 0-Is; and OR = 0.32 and CI = 0.1-1.03 for LST-G vs. 0-Is) and increasing size (OR = 1.02 and CI = 1.01-1.04 for a 1 mm increase) were significantly associated with an increasing degree of fibrosis. The model had fair discriminating ability in the derivation group (AUROC = 0.61 and CI = 0.52-0.69 for F1-F2 vs. F0 fibroses; AUROC = 0.61 and CI = 0.45-0.77 for F2 vs. F0-F1 fibroses) and in the validation group (AUROC = 0.71 and CI = 0.59-0.83 for F1-F2 vs. F0 fibroses; AUROC = 0.65 and CI = 0.52-0.77 for F2 vs. F0-F1 fibroses). Conclusions: Our findings introduce a new tool for the stratification of ESD technical difficulty based on lesion size and morphological characteristics which could become crucial during the procedure's planning process.
RESUMO
BACKGROUND: The efficacy of endoscopic ultrasound-guided liver biopsy (EUS-LB) compared to percutaneous liver biopsy (PC-LB) remains uncertain. METHODS: Our data consist of randomized controlled trials (RCTs) comparing EUS-LB to PC-LB, found through a literature search via PubMed/Medline and Embase. The primary outcome was sample adequacy, whereas secondary outcomes were longest and total lengths of tissue specimens, diagnostic accuracy, and number of complete portal tracts (CPTs). RESULTS: Sample adequacy did not significantly differ between EUS-LB and PC-LB (risk ratio [RR] 1.18; 95% confidence interval [CI] 0.58-2.38; p = 0.65), with very low evidence quality and inadequate sample size as per trial sequential analysis (TSA). The two techniques were equivalent with respect to diagnostic accuracy (RR: 1; CI: 0.95-1.05; p = 0.88), mean number of complete portal tracts (mean difference: 2.29, -4.08 to 8.66; p = 0.48), and total specimen length (mean difference: -0.51, -20.92 to 19.9; p = 0.96). The mean maximum specimen length was significantly longer in the PC-LB group (mean difference: -3.11, -5.51 to -0.71; p = 0.01), and TSA showed that the required information size was reached. CONCLUSION: EUS-LB and PC-LB are comparable in terms of diagnostic performance although PC-LB provides longer non-fragmented specimens.
RESUMO
Pancreatic fluid collections (PFCs), including pancreatic pseudocysts (PPs) and walled-off pancreatic necrosis (WON), are common complications of pancreatitis and pancreatic surgery. Historically, the treatment of these conditions has relied on surgical and radiological approaches. The treatment of patients with PFCs has already focused toward an endoscopy-based approach, and with the development of dedicated lumen-apposing metal stents (LAMS), it has almost totally shifted towards interventional Endoscopic Ultrasound (EUS)-guided procedures. However, there is still limited consensus on several aspects of PFCs treatment within the multidisciplinary management. The interventional endoscopy and ultrasound (i-EUS) group is an Italian network of clinicians and scientists with special interest in biliopancreatic interventional endoscopy, especially interventional EUS. This manuscript focuses on the second part of the results of a consensus conference organized by i-EUS, with the aim of providing evidence-based guidance on several intra- and post-procedural aspects of PFCs drainage, such as clinical management and follow-up.
RESUMO
Pancreatic fluid collections (PFCs), including pancreatic pseudocysts (PPs) and walled-off pancreatic necrosis (WON), are common complications of pancreatitis and pancreatic surgery. Historically, the treatment of these conditions has relied on surgical and radiological approaches; however, it has later shifted toward an endoscopy-based approach. With the development of dedicated lumen-apposing metal stents (LAMS), interventional Endoscopic Ultrasound (EUS)-guided procedures have become the standard approach for PFC drainage. However, there is still limited consensus on several aspects of the multidisciplinary management of PFCs. The interventional endoscopy and ultrasound (i-EUS) group is an Italian network of clinicians and scientists with special interest in biliopancreatic interventional endoscopy, especially interventional EUS. This manuscript describes the first part of the results of a consensus conference organized by i-EUS with the aim of providing evidence-based guidance on aspects such as indications for treating PFCs, the timing of intervention, and different technical strategies for managing patients with PFCs.
RESUMO
BACKGROUND: Although endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using lumen-apposing metal stents (LAMS) has become one of the treatments of choice for acute cholecystitis (AC) in fragile patients, scant data are available on real-life settings and long-term outcomes. METHODS: We performed a multicenter retrospective study including EUS-guided GBD using LAMS for AC in 19 Italian centers from June 2014 to July 2020. The primary outcomes were technical and clinical success, and the secondary outcomes were the rate of adverse events (AE) and long-term follow-up. RESULTS: In total, 116 patients (48.3% female) were included, with a mean age of 82.7 ± 11 years. LAMS were placed, transgastric in 44.8% of cases, transduodenal in 53.3% and transjejunal in 1.7%, in patients with altered anatomy. Technical success was achieved in 94% and clinical success in 87.1% of cases. The mean follow-up was 309 days. AEs occurred in 12/116 pts (10.3%); 8/12 were intraprocedural, while 1 was classified as early (<15 days) and 3 as delayed (>15 days). According to the ASGE lexicon, two (16.7%) were mild, three (25%) were moderate, and seven (58.3%) were severe. No fatal AEs occurred. In subgroup analysis of 40 patients with a follow-up longer than one year, no recurrence of AC was observed. CONCLUSIONS: EUS-GBD had high technical and clinical success rates, despite the non-negligible rate of AEs, thus representing an effective treatment option for fragile patients.
