ABSTRACT
BACKGROUND AND AIMS: Endoscopic ultrasound-guided pancreatic duct intervention (EUS-PDI) is one of the most technically challenging procedures. There remains a knowledge gap due to its rarity. The aim is to report the accumulated EUS-PDI experience in a tertiary center. METHODS: Single tertiary center, retrospective cohort study of prospectively collected data during the study period, from January 2013 to June 2021. RESULTS: In total, 14 patients (85% male; mean age, 61 years, range 37-81) and 25 EUS-PDI procedures for unsuccessful endoscopic retrograde pancreatography (ERP) were included. Principal etiology was chronic pancreatitis with pancreatic duct obstruction (78%). EUS-guided assisted (colorant and/or guidewire, rendezvous) ERP was performed in 14/25 (56%); and transmural drainage in 11 procedures, including pancreaticogastrosmy in 9/25 (36%) and pancreaticoduodenostomy in 2/25 (8%). Overall technical and clinical success was 78.5% (11/14). Three (21%) patients required a second procedure with success in all cases. Two failed cases required surgery. Three (21%) adverse events (AEs) were noted (fever, n=1; perforation, n=1; pancreatitis, n=1). Patients underwent a median of 58 months (range 24-108) follow-up procedures for re-stenting. Spontaneous stent migration was detected in 50% of cases. CONCLUSIONS: EUS-PDI is an effective salvage therapy for unsuccessful ERP, although 21% of patients may still experience AEs. In case of EUS-guided rendezvous failure, it can cross over to a transmural drainage.
ABSTRACT
BACKGROUND AND AIMS: Endoscopic band ligation (EBL) without resection combined with single-incision needle-knife (SINK) biopsy sampling may have a positive impact on small GI subepithelial tumor (SET) management, but the method needs to be tested. The aim was to evaluate the feasibility of this strategy in small-sized SETs. METHODS: This prospective multicenter observational cohort study in 7 centers included patients with SETs ≤15 mm (confirmed by EUS) between March 2017 and March 2020. The primary outcome was clinical success at 4 weeks, defined as complete SET disappearance on EUS. Secondary outcomes were long-term (1-year) clinical success, technical difficulty level, clinical impact, yield pathology, and safety. RESULTS: Of 273 patients screened, 122 (62.3% women; mean age, 60.9 ± 13.2 years) were included with SETs (mean size, 9 ± 2.8 mm; gastric location, 77%; superficial layer dependence, 63%). The primary endpoint was achieved in 73.6% of patients (95% confidence interval [CI], 64.8-81.2). At the 1-year follow-up, the success rate was 68.4% (95% CI, 59.1-76.8). A favorable clinical impact was observed in 97 cases (79.5%; 95% CI, 71.3-86.3). Pathology diagnosis was known in 70%. Potentially malignant lesions were present in 24.7%. The related adverse events rate was 4.1% (95% CI, 1.3-9.3; all mild: 2 bleeding, 2 abdominal pain). On multivariable analysis, the ≤10-mm SET group was associated with a greater success rate (1 year, 87%; relative risk, 5.07; 95% CI, 2.63-9.8) and clinical impact rate (92.7%; relative risk, 6.15; 95% CI, 2.72-13.93). CONCLUSIONS: EBL plus SINK biopsy sampling seems to be feasible and safe, and it may offer a favorable clinical impact in small-sized SETs. In particular, SETs ≤10 mm are the best candidates.

The numerous causes underlying mediastinal lesions require different diagnostic and therapeutic approaches, including conservative, minimally invasive, and surgical interventions. Solid lesions of a malignant nature, mostly located in the anterior mediastinum, are properly treated with surgical resection either with or without adjuvant schemes. In contrast, a surveillance program is usually recommended with solid benign tumors, depending on their size and related symptomatology. In the management of mediastinal collections, when a drainage intervention is required (suspicion of infection and symptomatology), a minimally invasive nonsurgical procedure or thoracic surgery is considered. The minimally invasive nonsurgical procedures that can be available are percutaneous radiology-guided imaging (abdominal ultrasound (US) or computed tomography (CT) scan), complete single-aspiration guided by endoscopic ultrasound (EUS) or endobronchial ultrasound (EBUS), and transmural drainage guided by EUS. Surgical debridement is feasible to treat collections, but as this entails considerable risk of postoperative complications, it is chosen only when other minimally invasive therapies are not possible. The published literature related to the interventional endoscopic approach to mediastinal lesions is scarce. Nevertheless, reports in this field reveal that interventional EUS may have a role in both the diagnosis of and therapeutic approach to mediastinal lesions, mainly in the management of mediastinal collections.
ABSTRACT
Introducción: La pandemia producida por el virus SARS-CoV-2 ha generado un grave impacto en el funcionamiento de las unidades de endoscopia digestiva. La Asociación Española de Gastroenterología y la Sociedad Española de Endoscopia Digestiva (AEG-SEED) han propuesto la utilización de la guía European Panel on the Appropriateness of Gastrointestinal Endoscopy II (EPAGE) para la gestión de las colonoscopias pospuestas.Objetivo: Evaluar la guía EPAGE como herramienta de gestión en comparación con el test de sangre oculta en heces inmunológico (TSOHi) y con una calculadora de riesgo (CR), que incluye la edad, el sexo y el TSOHi, para la detección de cáncer colorrectal (CCR) y lesión significativa colónica (LSC).Métodos: Estudio unicéntrico prospectivo. Se incluyeron 743 pacientes derivados para una colonoscopia diagnóstica. Se clasificó cada solicitud según EPAGE en apropiada, indeterminada e inapropiada. Se les entregó un TSOHi y se calculó el valor de la CR.ResultadosEl TSOHi (p<0,001), pero no EPAGE (p = 0,742), fue una variable independiente de riesgo de CCR. El área bajo la curva receiver operating characteristic (ROC) de EPAGE, TSOHi y CR fue: 0,61(IC 95% 0,49 a 0,75), 0,95 (0,93 a 0,97) y 0,90 (0,87 a 0,93) para CCR; y 0,55 (0,49 a 0,61), 0,75 (0,69 a 0,813) y 0,78 (0,73 a 0,83) para LSC, respectivamente. El número necesario de colonoscopias para detectar un CCR y una LSC fue de 38 y siete para EPAGE, de siete y dos para TSOHi, y de 19 y cuatro para CR ≥ cinco puntos, respectivamente.Conclusión: La EPAGE, a diferencia del TSOHi, no es adecuada para seleccionar a los pacientes candidatos a colonoscopia diagnóstica para la detección de CCR. El TSOHi, en combinación con la edad y el sexo, es la estrategia correcta para gestionar la demanda de endoscopia en un escenario de acceso restrictivo.
Introduction: The pandemic caused by the SARS-CoV-2 virus has had a serious impact on the functioning of gastrointestinal endoscopy Units. The Asociación Española de Gastroenterología (AEG) and the Sociedad Española de Endoscopia Digestiva (SEED) have proposed the EPAGE guidelines for managing postponed colonoscopies.ObjectiveTo evaluate the EPAGE guidelines as a management tool compared to the immunologic faecal occult blood test (iFOBT) and compared to risk score (RS) that combines age, sex and the iFOBT for the detection of colorectal cancer (CRC) and significant bowel disease (SBD).Methods: A prospective, single-centre study enrolling 743 symptomatic patients referred for a diagnostic colonoscopy. Each order was classified according to the EPAGE guidelines as appropriate, indeterminate or inappropriate. Patients underwent an iFOBT and had their RS calculated.Results: The iFOBT (p<0.001), but not the EPAGE guidelines (p = 0.742), was an independent predictive factor of risk of CRC. The ROC AUCs for the EPAGE guidelines, the iFOBT and the RS were 0.61 (95% CI 0.49-0.75), 0.95 (0.93-0.97) and 0.90 (0.87-0.93) for CRC, and 0.55 (0.49-0.61), 0.75 (0.69-0.813) and 0.78 (0.73-0.83) for SBD, respectively. The numbers of colonoscopies needed to detect a case of CRC and a case of SBD were 38 and seven for the EPAGE guidelines, seven and two for the iFOBT, and 19 and four for a RS ≥5 points, respectively.Conclusion: The EPAGE guidelines, unlike the iFOBT, is not suitable for screening candidate patients for a diagnostic colonoscopy to detect CRC. The iFOBT, in combination with age and sex, is the most suitable strategy for managing demand for endoscopy in a restricted-access situation

Background and study aims Traditionally in the case of a vascular interposition, endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has been contraindicated. A transvascular route (TV) is feasible and probably a safe alternative approach in selected patients, but data are scarce. The primary aim of this study was to analyze the diagnostic yield and safety of EUS-TV-FNA in thoracic and abdominal lesions. Secondary aims included evaluation of the clinical impact and technical aspects. Patients and methods A retrospective multicenter study was conducted with inclusion of all consecutive patients that underwent EUS-TV-FNA from July 2007 to January 2020. Feasibility, cytopathology, procedure details, and safety were evaluated. Univariate analysis was performed to identify variables associated with incidents, cytopathological diagnosis, and clinical impact. Results Data were collected from a total of 49 cases and 50 EUS-TV-FNAs. The aorta (nâ=â19) and portal system (nâ=â17) were the most frequently punctured. The most frequent lesions were mediastinal lymph nodes (nâ=â13) and pancreatic tumors (nâ=â11). The diagnostic yield was 86â%, and there were nondiagnostic samples in seven cases. Overall sensitivity, specificity, and accuracy were 88â% (95â%CI,0.74-0.96), 100â% (95â%CI,0.59-1), and 90â% (95â%CI,0.78-0.96), respectively. Only three incidents were detected: two mural hematomas and a self-limited bleeding of gastroduodenal artery. In most patients, there was a significant impact on clinical management (88â%). Arterial vessel and ASA-III had a trend with incidents (both, P â<â0.08). Rapid on-site evlauation was found to be an independent predictor for obtaining a conclusive sample (OR 6.2; 95â%CI, 1.06-36.73, P â<â0.04). Conclusions EUS-TV-FNA is feasible, seems to be safe, and can be recommended when no other targets are available, and the information obtained would impact on the clinical plan.
ABSTRACT
OBJECTIVE: Outside clinical trials, the effectiveness of chromoendoscopy (CE) for long-standing IBD surveillance is controversial. We aimed to assess the effectiveness of CE for neoplasia detection and characterisation, in real-life. DESIGN: From June 2012 to 2014, patients with IBD were prospectively included in a multicentre cohort study. Each colonic segment was evaluated with white light followed by 0.4% indigo carmine CE. Specific lesions' features were recorded. Optical diagnosis was assessed. Dysplasia detection rate between expert and non-expert endoscopists and learning curve were ascertained. RESULTS: Ninety-four (15.7%) dysplastic (1 cancer, 5 high-grade dysplasia, 88 low-grade dysplasia) and 503 (84.3%) non-dysplastic lesions were detected in 350 patients (47% female; mean disease duration: 17â years). Colonoscopies were performed with standard definition (41.5%) or high definition (58.5%). Dysplasia miss rate with white light was 40/94 (57.4% incremental yield for CE). CE-incremental detection yield for dysplasia was comparable between standard definition and high definition (51.5% vs 52.3%, p=0.30). Dysplasia detection rate was comparable between expert and non-expert (18.5% vs 13.1%, p=0.20). No significant learning curve was observed (8.2% vs 14.2%, p=0.46). Sensitivity, specificity, and positive and negative predictive values for dysplasia optical diagnosis were 70%, 90%, 58% and 94%, respectively. Endoscopic characteristics predictive of dysplasia were: proximal location, loss of innominate lines, polypoid morphology and Kudo pit pattern III-V. CONCLUSIONS: CE presents a high diagnostic yield for neoplasia detection, irrespectively of the technology and experience available in any centre. In vivo, CE optical diagnosis is highly accurate for ruling out dysplasia, especially in expert hands. Lesion characteristics can aid the endoscopist for in situ therapeutic decisions.

BACKGROUND AND AIM: Intravenous corticosteroids remain the first line therapy for severe attacks of ulcerative colitis although up to 30-40% of patients do not respond to treatment. The availability of alternative therapies to colectomy and the knowledge of early predictors of response to corticosteroids should have improved the clinical outcomes of patients with severe refractory ulcerative colitis. The aim of the study is to describe the current need, way of use, and efficacy of rescue therapies, as well as colectomy rates in patients with severe ulcerative colitis flares. METHODS: Between January 2005 and December 2011, all patients admitted in three referral centres for a severe ulcerative colitis flare who received intravenous corticosteroids were identified and clinical and biological data were accurately collected. Patients were followed-up until colectomy, death, or date of data collection. RESULTS: Sixty-two flares were included. Initial efficacy of intravenous corticosteroids (mild activity or inactive disease without rescue treatment, at day 7 after starting intravenous corticosteroids) was achieved in 50% of flares, and rescue therapies were used in 27 episodes (43%). After a median follow-up of 18 months, the colectomy rate was 6.5%. Failed oral corticosteroids for the index flare were the only baseline feature that predicted the need for rescue therapy and colectomy. CONCLUSIONS: There is a marked reduction in the colectomy rate and an increased use of medical rescue therapies as compared to historical series. Patients worsening while on oral corticosteroids for a moderate flare are at high risk of rescue therapy and colectomy and, therefore, should be directly treated with rescue therapies instead of attempting intravenous corticosteroids.
