RESUMEN
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.
RESUMEN
INTRODUCTION: The natural history of autoimmune gastritis (AIG) has been poorly described. In this study, we report the long-term natural history and clinical clustering of the full spectrum of AIG, from the potential to the complicated stage. METHODS: Prospective single-center study conducted in a tertiary referral center. Patients with AIG at any stage (0 = potential; 1 = early; 2 = florid; 3 = severe; and 4 = complicated) were enrolled (January 2000-December 2022). The histopathological evolution, the clinical presentation, and the correlates of evolution of potential AIG were assessed. RESULTS: Four hundred ninety-eight patients with AIG (mean age 56.7 ± 15.2 years, F:M ratio 2.5:1) were included, of whom 93 experienced potential AIG. The maximum disease duration was 27 years (median 18, interquartile range 14-23), while the overall median follow-up was 52 months (interquartile range 12-95). Age was significantly lower in stage 0 compared with that in the other stages. Accidental histologic evidence and hematologic findings were the most common clusters of diagnosis. The overall median rate of progression was 7.29 per 100 persons/yr (95% confidence interval [CI] 6.19-8.59), while the stage-specific rates of progression were 10.85 (stage 0; 95% CI 7.75-15.18), 14.83 (stages 1-2; 95% CI 11.89-18.49), and 2.68 (stage 3; 95% CI 1.88-3.84). Newly onset neoplastic complications at follow-up occurred in 41/483 patients (8.5%; 23 neuroendocrine tumors and 18 epithelial dysplasia). No cases of adenocarcinoma were noticed. Male sex was associated with a greater likelihood of evolving from potential AIG to overt AIG. DISCUSSION: AIG is a progressive disorder, with a virtually absent risk of gastric adenocarcinoma. Patients with potential AIG should be monitored because they carry a high risk of evolving into overt AIG.
RESUMEN
INTRODUCTION: To describe the clinical features and the risk of developing gastric tumors in patients with autoimmune gastritis (AIG). METHODS: This was a retrospective, longitudinal, multicenter study conducted at 8 Italian tertiary referral centers. We retrieved clinical data from all histologically proven patients with AIG. Differences between Helicobacter pylori -exposed vs H. pylori -naive and anti-parietal cell antibody (PCA)-positive vs PCA-negative patients were investigated. The rate of gastric adenocarcinoma and type 1 gastric neuroendocrine neoplasm (gNEN) was assessed. A multivariable model for factors associated with gNEN was fitted. RESULTS: A total of 1,598 patients with AIG (median age 58 years, interquartile range 46-68; F:M ratio 2.7:1) were included. H. pylori -naive patients were more likely to have a first-degree family history of AIG (14.7% vs 8.9%; P = 0.012), type 1 diabetes mellitus (4.9% vs 2.3%; P = 0.025), and pernicious anemia (30.9% vs 21.1%; P = 0.003). PCA-positive patients had significantly more associated autoimmune diseases (59.0% vs 42.9%; P < 0.001) and were more likely to have been diagnosed by a case-finding strategy (15.3% vs 2.6%; P < 0.001). Overall, 15 cases (0.9%) of gastric adenocarcinoma and 153 cases (9.6%) of gNEN occurred, with a global rate of 0.12 (95% confidence interval [CI] 0.07-0.20) and 1.22 (95% CI 1.03-1.42) per 100 person/year, respectively. Having a vitamin B12/iron deficiency manifestation at AIG diagnosis was associated with a 16.44 (95% CI 9.94-27.20 P < 0.001) hazard ratio of gNEN. DISCUSSION: The "pure" AIG pattern has typical features of an autoimmune disease and seems to be unrelated to H. pylori . In a tertiary referral setting, the risk of developing overt gastric adenocarcinoma is low, while patients with vitamin B12 deficiency complications at onset may benefit from a more intense endoscopic follow-up for early gNEN detection.
RESUMEN
BACKGROUND AND AIMS: Ampullary lesions (ALs) of the minor duodenal papilla are extremely rare. Endoscopic papillectomy (EP) is a routinely used treatment for AL of the major duodenal papilla, but the role of EP for minor AL has not been accurately studied. METHODS: We identified 20 patients with ALs of minor duodenal papilla in the multicentric database from the Endoscopic Papillectomy vs Surgical Ampullectomy vs Pancreatitcoduodenectomy for Ampullary Neoplasm study, which included 1422 EPs. We used propensity score matching (nearest-neighbor method) to match these cases with ALs of the major duodenal papilla based on age, sex, histologic subtype, and size of the lesion in a 1:2 ratio. Cohorts were compared by means of chi-square or Fisher exact test as well as Mann-Whitney U test. RESULTS: Propensity score-based matching identified a cohort of 60 (minor papilla 20, major papilla 40) patients with similar baseline characteristics. The most common histologic subtype of lesions of minor papilla was an ampullary adenoma in 12 patients (3 low-grade dysplasia and 9 high-grade dysplasia). Five patients revealed nonneoplastic lesions. Invasive cancer (T1a), adenomyoma, and neuroendocrine neoplasia were each found in 1 case. The rate of complete resection, en-bloc resection, and recurrences were similar between the groups. There were no severe adverse events after EP of lesions of minor papilla. One patient had delayed bleeding that could be treated by endoscopic hemostasis, and 2 patients showed a recurrence in surveillance endoscopy after a median follow-up of 21 months (interquartile range, 12-50 months). CONCLUSIONS: EP is safe and effective in ALs of the minor duodenal papilla. Such lesions could be managed according to guidelines for EP of major duodenal papilla.

BACKGROUND: Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is a valid option for EUS-guided biliary drainage that has been increasingly used in the last decade. The aims of this study were to provide a systematic review with meta-analysis and meta-regression of the features and outcomes of this procedure. METHODS: The MEDLINE, Scopus, Web of Science, and Cochrane databases were searched for literature pertinent to EUS-HGS. Meta-analysis of the proportions and meta-regression of potential modifiers of the main outcome measures were applied. The main outcome was technical success; secondary outcomes were clinical success and procedure-related adverse events (AEs). RESULTS: 33 studies, including 1644 patients, were included in the meta-analysis. Malignant biliary obstruction (MBO) was the underlying cause in almost all cases (99.6%); the main indications for EUS-HGS were duodenal/papillary invasion (34.8%), surgically altered anatomy (18.4%), and hilar stenosis (16.0%). The pooled technical success of EUS-HGS was 97.7% (95%CI 96.1%-99.0%; I 2 = 0%), the intention-to-treat clinical success rate was 88.1% (95%CI 84.7%-91.2%; I 2 = 33.9%), and procedure-related AEs occurred in 12.0% (95%CI 9.8%-14.5%; I 2 = 20.4%), with cholangitis/sepsis (2.8%) and bleeding (2.3%) the most frequent. The rate of procedure-related AEs was lower with the use of dedicated stents on univariable meta-regression analysis. Meta-regression showed that technical success and clinical success rates were modified by the centers' experience (>4/year). CONCLUSIONS: EUS-HGS represents an effective and safe procedure for EUS-guided biliary drainage in patients with MBO. Future studies should address the impact of center experience, patient selection, and the use of dedicated stents to improve performance of this technique.
RESUMEN
BACKGROUND: Endoscopic full-thickness resection (EFTR) is an effective and safe technique for nonlifting colorectal lesions. Technical issues or failures with the full-thickness resection device (FTRD) system are reported, but there are no detailed data. The aim of our study was to quantify and classify FTRD technical failures. METHODS: We performed a retrospective study involving 17 Italian centers with experience in advanced resection techniques and the required devices. Each center shared and classified all prospectively collected consecutive failures during colorectal EFTR using the FTRD from 2018 to 2022. The primary outcome was the technical failure rate and their classification; secondary outcomes included subsequent management, clinical success, and complications. RESULTS: Included lesions were mainly recurrent (52â%), with a mean (SD) dimension of 18.4 (7.5) mm. Among 750 EFTRs, failures occurred in 77 patients (35 women; mean [SD] age 69.4 [8.9] years). A classification was proposed: type I, snare noncutting (53â%); type II, clip misdeployment (31â%); and type III, cap misplacement (16â%). Among endoscopic treatments completed, rescue endoscopic mucosal resection was performed in 57 patients (74â%), allowing en bloc and R0 resection in 71â% and 64â%, respectively. The overall adverse event rate was 27.3â%. Pooled estimates for the rates of failure, complications, and rescue endoscopic therapy were similar for low and high volume centers (Pâ=â0.08, Pâ=â0.70, and Pâ=â0.71, respectively). CONCLUSIONS: Colorectal EFTR with the FTRD is a challenging technique with a non-negligible rate of technical failure and complications. Experience in rescue resection techniques and multidisciplinary management are mandatory in this setting.
RESUMEN
BACKGROUND: Clips are endoscopic mechanical devices with tensile and closure strength that can approximate tissue and provide hemostasis through a tamponade effect. Clips are ubiquitously used in endoscopic practice, and numerous studies have validated the clinical efficacy of clips, with recent guidelines recommending them as a first-line intervention for recurrent and persistent nonvariceal gastrointestinal bleeding. However, the safety profile for these devices has yet to be delineated, thus, we aim to investigate this feature by examining the adverse events reported to the Food and Drug Administration. METHODS: Postmarketing surveillance data from the Food and Drug Administration Manufacturer And User Facility Device Experience database were analyzed from January 2012 to January 2021. The Manufacturer And User Facility Device Experience database is a reporting software and does not independently verify the details of complications. RESULTS: Two thousand five hundred forty reports were issued, of which 287 were patient adverse events and 2766 were device problems. Activation, separation, and positioning issues were most common. No consequences or clinically significant impact on patients were seen in 1968 reports. Foreign bodies were seen in 97 cases, hemorrhage in 57 cases, tissue damage in 42 cases, embedded clips in tissues/plaques in 16 cases, perforation in 15 cases, lacerations in 6 cases, and infection in 3 cases. CONCLUSIONS: While the most commonly reported device problems involved activation, separation, and positioning, most patients were clinically unaffected. Moreover, perforation and infection were exceedingly rare, further highlighting the safety profile of endoscopic clips.

BACKGROUND: Duodenoscope-related multidrug-resistant organism (MDRO) infections raise concerns. Disposable duodenoscopes have been recently introduced in the market and approved by regulatory agencies with the aim to reduce the risk of endoscopic retrograde cholangiopancreatography (ERCP) associated infections. The aim of this study was to evaluate the outcome of procedures performed with single-use duodenoscopes in patients with clinical indications to single-operator cholangiopancreatoscopy. METHODS: This is a multicenter international, retrospective study combining all patients who underwent complex biliopancreatic interventions using the combination of a single-use duodenoscope and a single-use cholangioscope. The primary outcome was technical success defined as ERCP completion for the intended clinical indication. Secondary outcomes were procedural duration, rate of cross-over to reusable duodenoscope, operator-reported satisfaction score (1 to 10) on performance rating of the single-use duodenoscope, and adverse event (AE) rate. RESULTS: A total of 66 patients (26, 39.4% female) were included in the study. ERCP was categorized according to ASGE ERCP grading system as 47 (71.2%) grade 3 and 19 (28.8%) grade 4. The technical success rate was 98.5% (65/66). Procedural duration was 64 (interquartile range 15-189) min, cross-over rate to reusable duodenoscope was 1/66 (1.5%). The satisfaction score of the single-use duodenoscope classified by the operators was 8.6 ± 1.3 points. Four patients (6.1%) experienced AEs not directly related to the single-use duodenoscope, namely 2 post-ERCP pancreatitis (PEP), 1 cholangitis and 1 bleeding. CONCLUSIONS: Single-use duodenoscope is effective, reliable and safe even in technically challenging procedures with a non-inferiority to reusable duodenoscope, making these devices a viable alternative to standard reusable equipment.

Background and Objectives: The implementation and monitoring of the European Society of Gastrointestinal Endoscopy (ESGE) performance measures for colonoscopy are suboptimal in clinical practice. Electronic reporting systems may play an important role in data retrieval. We aimed to define the possibility of systematically assessing and monitoring ESGE performance measures for colonoscopy through reporting systems. Materials and Methods: We conducted a survey during a nationwide event on the quality of colonoscopy held in Rome, Italy, in March 2023 by a self-administered questionnaire. Analyses were conducted overall and by workplace setting. Results: The attendance was 93% (M/F 67/26), with equal distribution of age groups, regions and public or private practices. Only about one-third (34%) and 21.5% of participants stated that their reporting system allows them to retrieve all the ESGE performance measures, overall and as automatic retrieval, respectively. Only 66.7% and 10.7% of respondents can systematically report the cecal intubation and the adenoma detection rate, respectively. The analysis according to hospital setting revealed no significant difference for all the items. Conclusions: We found a generalized lack of systematic tracking of performance measures for colonoscopy due to underperforming reporting systems. Our results underline the need to update reporting systems to monitor the quality of endoscopy practice in Italy.

Background and Objectives: Biliary drainage (BD) in patients with surgically altered anatomy (SAA) could be obtained endoscopically with different techniques or with a percutaneous approach. Every endoscopic technique could be challenging and not clearly superior over another. The aim of this survey is to explore which is the standard BD approach in patients with SAA. Materials and Methods: A 34-question online survey was sent to different Italian tertiary and non-tertiary endoscopic centers performing interventional biliopancreatic endoscopy. The core of the survey was focused on the first-line and alternative BD approaches to SAA patients with benign or malignant obstruction. Results: Out of 70 centers, 39 answered the survey (response rate: 56%). Only 48.7% of them declared themselves to be reference centers for endoscopic BD in SAA. The total number of procedures performed per year is usually low, especially in non-tertiary centers; however, they have a low tendency to refer to more experienced centers. In the case of Billroth-II reconstruction, the majority of centers declared that they use a duodenoscope or forward-viewing scope in both benign and malignant diseases as a first approach. However, in the case of failure, the BD approach becomes extremely heterogeneous among centers without any technique prevailing over the others. Interestingly, in the case of Roux-en-Y, a significant proportion of centers declared that they choose the percutaneous approach in both benign (35.1%) and malignant obstruction (32.4%) as a first option. In the case of a previous failed attempt at BD in Roux-en-Y, the subsequent most used approach is the EUS-guided intervention in both benign and malignant indications. Conclusions: This survey shows that the endoscopic BD approach is extremely heterogeneous, especially in patients with Roux-en-Y reconstruction or after ERCP failure in Billroth-II reconstruction. Percutaneous BD is still taken into account by a significant proportion of centers in the case of Roux-en-Y anatomy. The total number of endoscopic BD procedures performed in non-tertiary centers is usually low, but this result does not correspond to an adequate rate of referral to more experienced centers.

Background and Objectives: Serum alpha-fetoprotein (AFP) is a recognized affordable oncological marker in patients with hepatocellular carcinoma (HCC). However, AFP's prognostic role has been assessed mainly after specific treatments, and no unanimously recognized cut-offs have been identified. The aim of this study is to investigate the prognostic role of different basal AFP cut-offs on survival and HCC course. Materials and Methods: In this single-center, retrospective study, all patients newly diagnosed with HCC between January 2009 and December 2021 were prospectively enrolled. Only patients suitable for curative HCC treatments were included in the analyses. Patients were stratified according to AFP cut-offs of 20, 200, 400, and 1000 ng/mL, which were correlated with survival outcomes and clinical parameters. Results: A total of 266 patients were analyzed, with a median follow-up time of 41.5 months. Median overall survival (OS) of all cohort was 43 months. At the multivariate Cox-regression analysis, AFP value ≥ 1000 ng/mL correlated with impaired OS (1-year OS: 67% vs. 88%, 5-year OS: 1% vs. 43%; p = 0.005); other risk factors were tumor dimension ≥ 5 cm (HR 1.73; p = 0.002), Child-Pugh class B-C (HR 1.72; p = 0.002), BCLC stage A (vs. 0) (HR 2.4; p = 0.011), and malignant portal vein thrombosis (HR 2.57; p = 0.007). AFP ≥ 1000 ng/mL was also associated with a reduced recurrence-free survival (HR 2.0; p = 0.038), while starting from AFP ≥ 20 ng/mL, a correlation with development of HCC metastases over time (HR 3.5; p = 0.002) was seen. AFP values ≥ 20 ng/mL significantly correlated with tumor size and higher histological grading; starting from AFP values ≥ 400 ng/mL, a significant correlation with Child-Pugh class B-C and female gender was also observed. Conclusions: Basal AFP correlates with relevant outcomes in patients with HCC. It could help identify patients at a higher risk of worse prognosis who might benefit from personalized surveillance and treatment programs. Prospective studies are needed to confirm these results.

Gastrojejunostomy is the principal method of palliation for unresectable malignant gastric outlet obstructions (GOO). Gastrojejunostomy was traditionally performed as a surgical procedure with an open approach butrecently, notable progress in the development of minimally invasive procedures such as laparoscopic gastrojejunostomies have emerged. Additionally, advancements in endoscopic techniques, including endoscopic stenting (ES) and endoscopic ultrasound-guided gastroenterostomy (EUS-GE), are becoming more prominent. ES involves the placement of self-expandable metal stents (SEMS) to restore luminal patency. ES is commonly the first choice for patients deemed unfit for surgery or at high surgical risk. However, although ES leads to rapid improvement of symptoms, it carries limitations like higher stent dysfunction rates and the need for frequent re-interventions. Recently, EUS-GE has emerged as a potential alternative, combining the minimally invasive nature of the endoscopic approach with the long-lasting effects of a gastrojejunostomy. Having reviewed the advantages and disadvantages of these different techniques, this article aims to provide a comprehensive review regarding the management of unresectable malignant GOO.

BACKGROUND AND AIMS: Previous studies have demonstrated that the ideal time for drainage of walled-off pancreatic fluid collections is 4 to 6 weeks after their development. However, some pancreatic collections, notably infected pancreatic fluid collections, require earlier drainage. Nevertheless, the optimal timing of the first intervention is unclear, and consensus data are sparse. The aim of this study was to evaluate the clinical efficacy and safety of EUS-guided drainage of pancreatic fluid collections <4 weeks after development compared with ≥4 weeks after development. METHODS: Search strategies were developed for PubMed, Embase, and Cochrane Library databases from inception. Outcomes of interest were technical success, defined as successful endoscopic placement of a lumen-apposing metal stent; clinical success, defined as a reduction in cystic collection size; and procedure-related adverse events. A random-effects model was used for analysis, and results are expressed as odds ratio (OR) with 95% confidence interval (CI). RESULTS: Six studies (630 patients) were included in our final analysis, in which 182 patients (28.9%) were enrolled in the early drainage cohort and 448 patients (71.1%) in the standard drainage cohort. The mean fluid collection size was 143.4 ± 18.8 mm for the early cohort versus 128 ± 19.7 mm for the standard cohort. Overall, technical success was equal in both cohorts. Clinical success did not favor either standard drainage or early drainage (OR, .39; 95% CI, .13-1.22; P = .11). No statistically significant differences were found in overall adverse events (OR, 1.67; 95% CI, .63-4.45; P = .31) or mortality (OR, 1.14; 95% CI, .29-4.48; P = .85). Hospital stay was longer for patients undergoing early drainage compared with standard drainage (23.7 vs 16.0 days, respectively). CONCLUSIONS: Both early (<4 weeks) and standard (≥4 weeks) drainage of walled-off pancreatic fluid collections offer similar technical and clinical outcomes. Patients requiring endoscopic drainage should not be delayed for 4 weeks.

BACKGROUND AND AIMS: EUS-guided gallbladder drainage (EUS-GBD) with lumen-apposing metal stents (LAMSs) has been reported as a rescue treatment with encouraging results for the relief of jaundice in patients with distal malignant biliary obstruction (DMBO) and after failure of both ERCP and EUS-guided choledochoduodenostomy. METHODS: This was a multicenter retrospective analysis of all cases of consecutive EUS-GBD with LAMSs used as a rescue treatment for patients with DMBO in 14 Italian centers from June 2015 to June 2020. Primary endpoints were technical and clinical success, whereas the secondary endpoint was the adverse event (AE) rate. RESULTS: Forty-eight patients (52.1% women) with a mean age of 74.3 ± 11.7 years were included in the study. Biliary stricture was related to pancreatic adenocarcinoma (85.4%), duodenal adenocarcinoma (2.1%), cholangiocarcinoma (4.2%), ampullary cancer (2.1%), colon cancer (4.2%), and metastatic breast cancer (2.1%). The mean diameter of the common bile duct was 13.3 ± 2.8 mm. LAMSs were placed transgastrically in 58.3% of cases and transduodenally in 41.7%. Technical success was 100%, whereas clinical success was 81.3%, with a mean total bilirubin reduction after 2 weeks of 66.5%. The mean procedure time was 26.4 minutes, and the mean hospital stay was 9.2 ± 8.2 days. AEs occurred in 5 patients (10.4%): 3 were classified as intraprocedural and 2 were classified as delayed because they occurred after >15 days. When the American Society for Gastrointestinal Endoscopy lexicon was used, 2 AEs were mild and 3 were moderate (2 buried LAMSs). The mean follow-up was 122 days. CONCLUSIONS: Our study shows that EUS-GBD with LAMSs used as a rescue treatment for patients affected by DMBO represents a valuable option in terms of technical and clinical success rates, with an acceptable AE rate. To the best of our knowledge, this is the largest study concerning the use of this procedure. (Clinical trial registration number: NCT03903523.).

BACKGROUND: Confirming the diagnosis, invasiveness, and disease extent of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas is challenging. The aim of this study was to summarize the literature on the efficacy and safety of peroral pancreatoscopy (POP) in the diagnosis of IPMN, including the impact of pre- and intraoperative POP on the management of IPMN. METHODS: The EMBASE, Medline Ovid, Web of Science, Cochrane CENTRAL, and Google Scholar databases were systematically searched for articles. Eligible articles investigated cohorts of patients who underwent POP for (suspected) IPMN. RESULTS: 25 articles were identified and included in this review; with 22 of these reporting on the diagnostic yield of POP in IPMN and 11 reporting on the effect of pre- or intraoperative POP on clinical decision-making. Cannulation and observation rates, and overall diagnostic accuracy were high across all studies. Frequently reported visual characteristics of IPMN were intraductal fish-egg-like lesions, hypervascularity, and granular mucosa. Overall, the adverse event rate was 12â%, primarily consisting of post-endoscopic retrograde cholangiopancreatography pancreatitis, with a pooled rate of 10â%, mostly of mild severity. Regarding the impact of POP on clinical decision-making, POP findings altered the surgical approach in 13â%-62â% of patients. CONCLUSION: POP is technically successful in the vast majority of patients with (suspected) IPMN, has a consistently high diagnostic accuracy, but an adverse event rate of 12â%. Data on intraoperative pancreatoscopy are scarce, but small studies suggest its use can alter surgical management. Future studies are needed to better define the role of POP in the diagnostic work-up of IPMN.

INTRODUCTION: Ampullary neuroendocrine neoplasia (NEN) is rare and evidence regarding their management is scarce. This study aimed to describe clinicopathological features, management, and prognosis of ampullary NEN according to their endoscopic or surgical management. METHODS: From a multi-institutional international database, patients treated with either endoscopic papillectomy (EP), transduodenal surgical ampullectomy (TSA), or pancreaticoduodenectomy (PD) for ampullary NEN were included. Clinical features, post-procedure complications, and recurrences were assessed. RESULTS: 65 patients were included, 20 (30.8%) treated with EP, 19 (29.2%) with TSA, and 26 (40%) with PD. Patients were mostly asymptomatic (n = 46; 70.8%). Median tumor size was 17 mm (12-22), tumors were mostly grade 1 (70.8%) and pT2 (55.4%). Two (10%) EP resulted in severe American Society for Gastrointestinal Enterology (ASGE) adverse post-procedure complications and 10 (50%) were R0. Clavien 3-5 complications did not occur after TSA and in 4, including 1 postoperative death (15.4%) of patients after PD, with 17 (89.5%) and 26 R0 resection (100%), respectively. The pN1/2 rate was 51.9% (n = 14) after PD. Tumor size larger than 1 cm (i.e., pT stage >1) was a predictor for R1 resection (p < 0.001). Three-year overall survival and disease-free survival after EP, TSA, and PD were 92%, 68%, 92% and 92%, 85%, 73%, respectively. CONCLUSION: Management of ampullary NEN is challenging. EP should not be performed in lesions larger than 1 cm or with a endoscopic ultrasonography T stage beyond T1. Local resection by TSA seems safe and feasible for lesions without nodal involvement. PD should be preferred for larger ampullary NEN at risk of nodal metastasis.

Background and Objectives: Bleeding is one of the most feared and frequent adverse events in the case of EUS-guided drainage of WOPN using lumen-apposing metal stents (LAMSs) and of direct endoscopic necrosectomy (DEN). When it occurs, its management is still controversial. In the last few years, PuraStat, a novel hemostatic peptide gel has been introduced, expanding the toolbox of the endoscopic hemostatic agents. The aim of this case series was to evaluate the safety and efficacy of PuraStat in preventing and controlling bleeding of WOPN drainage using LAMSs. Materials and Methods: This is a multicenter, retrospective pilot study from three high-volume centers in Italy, including all consecutive patients treated with the novel hemostatic peptide gel after LAMSs placement for the drainage of symptomatic WOPN between 2019 and 2022. Results: A total of 10 patients were included. All patients underwent at least one session of DEN. Technical success of PuraStat was achieved in 100% of patients. In seven cases PuraStat was placed for post-DEN bleeding prevention, with one patient experiencing bleeding after DEN. In three cases, on the other hand, PuraStat was placed to manage active bleeding: two cases of oozing were successfully controlled with gel application, and a massive spurting from a retroperitoneal vessel required subsequent angiography. No re-bleeding occurred. No PuraStat-related adverse events were reported. Conclusions: This novel peptide gel could represent a promising hemostatic device, both in preventing and managing active bleeding after EUS-guided drainage of WON. Further prospective studies are needed to confirm its efficacy.

Background: Obesity is a chronic disease that impairs quality of life and leads to several comorbidities. When conservative therapies fail, bariatric surgical options such as Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the most effective therapies to induce persistent weight loss. Over the last two decades, bariatric endoscopy has become a valid alternative to surgery in specific settings. Primary bariatric endoscopic therapies: Restrictive gastric procedures, such as intragastric balloons (IGBs) and endoscopic gastroplasty, have been shown to be effective in inducing weight loss compared to diet modifications alone. Endoscopic gastroplasty is usually superior to IGBs in maintaining weight loss in the long-term period, whereas IGBs have an established role as a bridge-to-surgery approach in severely obese patients. IGBs in a minority of patients could be poorly tolerated and require early removal. More recently, novel endoscopic systems have been developed with the combined purpose of inducing weight loss and improving metabolic conditions. Duodenal mucosal resurfacing demonstrated efficacy in this field in its early trials: significant reduction from baseline of HbA1c values and a modest reduction of body weight were observed. Other endoscopic malabsorptive have been developed but need more evidence. For example, a pivotal trial on duodenojejunal bypasses was stopped due to the high rate of severe adverse events (hepatic abscesses). Optimization of these more recent malabsorptive endoscopic procedures could expand the plethora of bariatric patients that could be treated with the intention of improving their metabolic conditions. Revisional bariatric therapies: Weight regain may occur in up to one third of patients after bariatric surgery. Different endoscopic procedures are currently performed after both RYGB and SG in order to modulate post-surgical anatomy. The application of argon plasma coagulation associated with endoscopic full-thickness suturing systems (APC-TORe) and Re-EndoSleeve have shown to be the most effective endoscopic treatments after RYGB and SG, respectively. Both procedures are usually well tolerated and have a very low risk of stricture. However, APC-TORe may sometimes require more than one session to obtain adequate final results. The aim of this review is to explore all the currently available primary and revisional endoscopic bariatric therapies focusing on their efficacy and safety and their potential application in clinical practice.

BACKGROUND AND AIMS: Artificial intelligence has been shown to increase adenoma detection rate (ADR) as the main surrogate outcome parameter of colonoscopy quality. To which extent this effect may be related to physician experience is not known. We performed a randomised trial with colonoscopists in their qualification period (AID-2) and compared these data with a previously published randomised trial in expert endoscopists (AID-1). METHODS: In this prospective, randomised controlled non-inferiority trial (AID-2), 10 non-expert endoscopists (<2000 colonoscopies) performed screening/surveillance/diagnostic colonoscopies in consecutive 40-80 year-old subjects using high-definition colonoscopy with or without a real-time deep-learning computer-aided detection (CADe) (GI Genius, Medtronic). The primary outcome was ADR in both groups with histology of resected lesions as reference. In a post-hoc analysis, data from this randomised controlled trial (RCT) were compared with data from the previous AID-1 RCT involving six experienced endoscopists in an otherwise similar setting. RESULTS: In 660 patients (62.3±10 years; men/women: 330/330) with equal distribution of study parameters, overall ADR was higher in the CADe than in the control group (53.3% vs 44.5%; relative risk (RR): 1.22; 95% CI: 1.04 to 1.40; p<0.01 for non-inferiority and p=0.02 for superiority). Similar increases were seen in adenoma numbers per colonoscopy and in small and distal lesions. No differences were observed with regards to detection of non-neoplastic lesions. When pooling these data with those from the AID-1 study, use of CADe (RR 1.29; 95% CI: 1.16 to 1.42) and colonoscopy indication, but not the level of examiner experience (RR 1.02; 95% CI: 0.89 to 1.16) were associated with ADR differences in a multivariate analysis. CONCLUSIONS: In less experienced examiners, CADe assistance during colonoscopy increased ADR and a number of related polyp parameters as compared with the control group. Experience appears to play a minor role as determining factor for ADR. TRIAL REGISTRATION NUMBER: NCT:04260321.

PURPOSE OF REVIEW: Upper gastrointestinal bleeding (UGIB) has significant morbidity and UGIB cases have been described in coronavirus disease 2019 (COVID-19) patients. Management of this condition can be challenging considering both the possible severe COVID-19-related pneumonia as well as the risk of the virus spreading from patients to health operators. The aim of this paper is to review the most recent studies available in the literature in order to evaluate the actual incidence of UGIB, its clinical and endoscopic manifestations and its optimal management. RECENT FINDINGS: UGIB has an incidence between 0.5% and 1.9% among COVID-19 patients, and it typically presents with melena or hematemesis. Peptic ulcers are the most common endoscopic findings. High Charlson Comorbidity Index (CCI), dialysis, acute kidney injury and advanced oncological disease increase the risk for UGIB. Although anticoagulants are commonly used in COVID-19 patients they are not associated with an increased incidence of UGIB. Conservative management is a common approach that results in similar outcomes compared to upper GI endoscopic treatment. Apparently, UGIB in COVID-19 seems not have a detrimental effect and only one study showed an increased mortality in those who developed UGIB during hospitalization. SUMMARY: Incidence of UGIB in COVID-19 patients is similar to that of the general population. Despite the widespread use of anticoagulants in these patients, they are not associated with an increased risk of UGIB. Conservative management could be an effective option, especially for patients that are at risk of intubation.
