In the last decades, Endoscopic ultrasound (EUS) has rapidly grown and evolved from being mainly a diagnostic procedure, to being an interventional and therapeutic tool in several pathological ...clinical scenarios. With the progressive growth in technical expertise and dedicated devices, interventional endoscopic ultrasound procedures (IEUSP) have shown high rates of technical and clinical success, together with a relatively safe profile. However, the description and the standardization of different and specific types of adverse events (AEs) are still scarce in literature, and, consequently, even less the management of AEs. The aim of this study is to critical review and to describe AEs related to each of the main IEUSP, and to provide an overview on the possible management strategies of endoscopic complications. Future studies and guidelines are surely required to reach a better standardization of different AEs and their best management.

It is difficult to differentiate between neoplastic and non-neoplastic gallbladder (GB) polyps before surgery. Endoscopic ultrasound-elastography (EUS-EG) is a non-invasive complementary diagnostic ...method. The utility of EUS-EG in the differential diagnosis of GB polyps has not been investigated. We aimed to investigate the diagnostic performance of EUS-EG for the differential diagnosis of GB polyps.
Patients with GB polyps were prospectively enrolled from June 2020 until November 2022. EUS-EG and semi-quantitative evaluation of the strain ratio (SR) were performed for differential diagnosis of GB polyps. Fifty-three eligible patients were divided into two groups based on the final diagnosis after surgery. Patient demographics, EUS characteristics, and SR values were compared. Receiver-operating characteristic (ROC) curve analysis was performed to determine the optimal cutoff SR value that discriminates between neoplastic and non-neoplastic GB polyps.
The median SR value for neoplastic polyps (32.93 interquartile range: 22.37–69.02) was significantly higher than for non-neoplastic polyps (5.40 2.36–14.44; p<0.001). There were significant differences in SR values between non-neoplastic, benign neoplastic (23.38 13.62–39.04), and malignant polyps (49.25 27.90–82.00). The optimal cut-off SR value to differentiate between neoplastic and non-neoplastic polyps was 18.4. In multivariable logistic regression, SR value >18.4 (odds ratio 33.604, 95% confidence interval 2.588–436.292) was an independent predictor of neoplastic polyps.
EUS-EG and SR values can be used as a supplementary method for evaluating GB polyps.

Background
Endoscopic injection of cyanoacrylate into gastric varices may be performed by EUS-guided fine needle injection (EUS-FNI) or direct endoscopic injection (DEI). The aim of this study is to ...compare the rate of recurrent GV bleeding and adverse events between DEI and EUS-FNI for treatment of GV.
Methods
In a single-center study, a retrospective cohort of patients with actively/recently bleeding or high-risk GV treated with DEI were compared with a prospective cohort of similar patients treated with EUS-FNI. Repeat endoscopy after index treatment was performed 3 months later or earlier if rebleeding occurred. The main outcomes assessed were rates of GV or overall rebleeding and adverse events.
Results
Forty patients (mean age 57.2 ± 9.1 years, 73% male) and 64 patients (mean age 58.0 ± 12.5 years, 52% male) underwent DEI and EUS-FNI, respectively. Compared to the DEI group, the frequency of isolated gastric varices type 1 (IGV1) were higher (
p
< 0.001) but MELD scores were lower (
p
= 0.004) in the EUS-FNI group. At index endoscopy, EUS-FNI utilized a lower mean volume of cyanoacrylate (2.0 ± 0.8 mL vs. 3.3 ± 1.3 mL;
p
< 0.001) and injected a greater number of varices (1.6 ± 0.7 vs. 1.1 ± 0.4;
p
< 0.001) compared to DEI. Overall, GV rebleeding 5/57 (8.8%) vs. 9/38 (23.7%);
p
= 0.045 and non-GV-related gastrointestinal bleeding 7/64 (10.9%) vs. 11/40 (27.5%);
p
= 0.030 were less frequent in the EUS-FNI group compared to the DEI group, respectively. Adverse event rates were similar (20.3% vs. 17.5%,
p
= 0.723).
Conclusions
EUS-guided CYA injection of active or recently bleeding GV in patients with portal hypertension appears to decrease the rate of GV rebleeding despite injection of more varices and less CYA volume during the initial endoscopic procedure. Adverse events are similar between the two groups. EUS-FNI appears to be the preferred strategy for treatment of these patients.

Malignant gastric outlet obstruction (MGOO) is a clinical condition characterized by the mechanical obstruction of the pylorus or the duodenum due to tumor compression/infiltration, with consequent ...reduction or impossibility of an adequate oral intake. MGOO is mainly secondary to advanced pancreatic or gastric cancers, and significantly impacts on patients' survival and quality of life. Patients suffering from this condition often present with intractable vomiting and severe malnutrition, which further compromise therapeutic chances. Currently, palliative strategies are based primarily on surgical gastrojejunostomy and endoscopic enteral stenting with self-expanding metal stents. Several studies have shown that surgical approach has the advantage of a more durable relief of symptoms and the need of fewer re-interventions, at the cost of higher procedure-related risks and longer hospital stay. On the other hand, enteral stenting provides rapid clinical improvement, but have the limit of higher stent dysfunction rate due to tumor ingrowth and a subsequent need of frequent re-interventions. Recently, a third way has come from interventional endoscopic ultrasound, through the development of endoscopic ultrasound-guided gastroenterostomy technique with lumen-apposing metal stent. This new technique may ideally encompass the minimal invasiveness of an endoscopic procedure and the long-lasting effect of the surgical gastrojejunostomy, and brought encouraging results so far, even if prospective comparative trial are still lacking. In this Review, we described technical aspects and clinical outcomes of the above-cited therapeutic approaches, and discussed the open questions about the current management of MGOO.
Endoscopy plays a fundamental role in the diagnosis, management, and treatment of inflammatory bowel disease (IBD). Colonoscopy, flexible sigmoidoscopy, and esophagogastroduodenoscopy have long been ...used in the care of patients with IBD. As endoscopic technologies have progressed, tools such as endoscopic ultrasound, capsule endoscopy, and balloon-assisted enteroscopy have expanded the role of endoscopy in IBD. Furthermore, chromoendoscopy has enhanced our ability to detect dysplasia in IBD. In this review article, we will focus on the roles, indications, and limitations of these tools in IBD. We will also discuss the most commonly used endoscopic scoring systems, as well as special considerations in post-surgical patients. Lastly, we will discuss the role of endoscopy in the diagnosis and management of fistulae and strictures.
Registry trials have found radial endobronchial ultrasound (r-EBUS) sensitivity to vary between institutions, suggesting that in clinical practice, r-EBUS sensitivity may be lower than reported in ...clinical trials. We performed a meta-analysis to update the estimates of r-EBUS sensitivity and to explore factors contributing to heterogeneity of results.
A systematic review using PubMed was performed through July 2018 to determine the sensitivity of r-EBUS for lung cancer, and to construct a summary receiver operating characteristic curve. The DerSimonian and Laird method was used to weight results. Subgroup analysis and meta-regression was used to identify sources of heterogeneity. Study quality was assessed using the QUADAS tool, and publication bias was tested using funnel plots.
Fifty-one studies with a total of 7,601 patients were included. r-EBUS pooled sensitivity was 0.72 (95% CI, 0.70-0.75), and area under the sROC curve was 0.96 (95% CI, 0.94-0.97). Significant heterogeneity was observed (I
= 76%; heterogeneity P < .01). We failed to demonstrate an association between sensitivity and air bronchus sign, average nodule size, use of fluoroscopy, virtual bronchoscopy, guide sheath, cancer prevalence, multicenter status, or consecutive enrollment. Rapid onsite cytology was associated with increased sensitivity (P = .01). The pooled pneumothorax rate was 0.7% (95% CI, 0.3%-1.1%). Funnel plots were asymmetrical, demonstrating sample size-related effects and possible publication bias.
r-EBUS has an excellent safety profile, but there is significant between-study heterogeneity. Sample size-related effects and possibly publication bias have led to overly optimistic estimates of the sensitivity of r-EBUS.
