Endoscopy-Related Bleeding and Thromboembolic Events in Patients on Direct Oral Anticoagulants or Vitamin K Antagonists.

BACKGROUND & AIMS: Few prospective studies have assessed the safety of direct oral anticoagulants (DOACs) in elective endoscopy. Our primary aim was to compare the risks of endoscopy-related gastrointestinal bleeding and thromboembolic events in patients on DOACs or vitamin K antagonists (VKAs) in this setting. Secondarily, we examined the impact of the timing of anticoagulant resumption on the risk of delayed bleeding in high-risk therapeutic procedures. METHODS: We conducted a multicenter, prospective, observational study from January 2018 to March 2020 of 1602 patients on oral anticoagulants (1004 on VKAs and 598 on DOACs) undergoing 1874 elective endoscopic procedures. Our primary outcomes were 90-day thromboembolic events and 30-day endoscopy-related gastrointestinal bleeding. The inverse probability of treatment weighting propensity score method was used for baseline covariate adjustment. RESULTS: The 2 groups had similar risks of endoscopy-related gastrointestinal bleeding (VKAs vs DOACs, 6.2% vs 6.7%; adjusted odds ratio [OR], 1.05; 95% CI, 0.67-1.65) and thromboembolic events (VKAs vs DOACs, 1.3% vs 1.5%; adjusted OR, 0.90; 95% CI, 0.34-2.38). In high bleeding risk procedures (n = 747), delayed anticoagulant resumption (> 48 hours or 24-48 hours vs < 24 hours) did not reduce the risk of postprocedural bleeding (10.3%, 9%, and 5.8%, respectively; adjusted P = .43). Hot and cold snare polypectomy were the most frequent high-risk interventions (41.8% and 39.8%, respectively). CONCLUSION: In a prospective study of patients on DOACs or VKAs undergoing elective endoscopy, endoscopy-related bleeding and thromboembolic events showed similar risk. Our study suggests that early anticoagulant resumption is safe in most patients, but more data are needed for advanced high-risk therapeutic procedures.

Seguimiento a largo plazo tras disección submucosa endoscópica de lesiones colorrectales en una cohorte española / No disponible

INTRODUCCIÓN: la disección submucosa endoscópica (DSE) en colon es una técnica en expansión en países occidentales. Existen pocos estudios con seguimiento a largo plazo. OBJETIVO: analizar supervivencia libre de enfermedad a largo plazo tras DSE y comparar las tasas de recidiva en función de diferentes factores. MATERIAL Y MÉTODOS: cohorte prospectiva de pacientes con DSE planeada entre septiembre de 2008 y diciembre de 2015. Cuando no fue posible técnicamente completar DSE se realizó disección híbrida en bloque o fragmentada. Se analizó la tasa de recurrencia a cinco años mediante curvas de Kaplan-Meier y se compararon en función de diferentes factores usando test de log-rank. RESULTADOS: se incluyó una cohorte inicial de 89 pacientes en los que se consiguió seguimiento en 69. De los 69 pacientes, en 31 (45 %) se realizó DSE; en once (16 %), DSE híbrida; y en 27 (39 %), DSE híbrida fragmentada. La mediana de seguimiento fue de 27 meses. La supervivencia libre de enfermedad a cinco años fue del 81 %. La media de endoscopias para eliminar la recurrencia fueron dos (rango 1-7) y ninguna requirió cirugía. La tasa de recidiva fue significativamente menor tras DSE "en bloque" respecto a fragmentada (15 % vs. 27 %, p = 0,036) y en resecciones R0 respecto a R1 (0 % vs. 26 %, p = 0,034). Las resecciones con márgenes laterales negativos en lesiones resecadas en bloque presentaron menor tasa de recidiva respecto a aquellas con márgenes afectos/desconocidos, que no alcanzaron la significación estadística (0 % vs. 28 %, p = 0,09). CONCLUSIONES: en nuestro estudio, la supervivencia libre de enfermedad a cinco años fue del 81 % y ningún paciente requirió cirugía durante el seguimiento. Las resecciones fragmentadas y R1 se asociaron de forma significativa con mayor tasa de recurrencia

Disección submucosa endoscópica en lesiones gástricas epiteliales: resultados a largo plazo en una cohorte española / No disponible

INTRODUCCIÓN: la disección submucosa endoscópica sobre lesiones gástricas (DSE-G) es una técnica que permite la resección de tumores gástricos precoces en bloque, con una tasa de curación similar a la cirugía y una morbimortalidad menor. OBJETIVO: analizar la supervivencia total, la supervivencia libre de enfermedad y la tasa de recidiva en pacientes sometidos a DSE-G en una cohorte española a lo largo de su evolución clínica. MATERIAL Y MÉTODOS: estudio observacional prospectivo. Inclusión de pacientes sometidos a DSE-G de 2008 a 2015, con seguimiento entre seis y 60 meses. Se analizó la recurrencia a cinco años mediante curvas de Kaplan-Meier y los resultados fueron comparados entre diferentes factores (en bloque vs. resección fragmentada, resecciones curativas R0 vs. margen lateral afecto ML+) usando test log-rank. RESULTADOS: se analizaron 35 pacientes sometidos a DSE-G, con una mediana de seguimiento de 33,62 meses. Se identificaron cuatro recidivas en este periodo (11,4%), tres de ellas tratadas mediante nueva DSE-G. La presencia de ML+ en la pieza histológica se relacionó con mayor tasa de recidiva local durante el seguimiento (p = 0,06). Las resecciones fragmentadas presentaron un mayor riesgo de recidiva pero sin detectarse diferencias estadísticamente significativas (p = 0,49). No se registraron fallecimientos por neoplasia gástrica ni gastrectomía por persistencia de enfermedad en este periodo. La tasa de supervivencia global en nuestra serie fue de 94,3%. CONCLUSIONES: la DSE-G realizada en nuestro medio permite una tasa elevada de curación a largo plazo evitando la cirugía. Estos resultados se asemejan a las series europeas publicadas y aún se encuentran lejos de las tasas de curación y recidiva de las cohortes asiáticas. Los casos de recidiva local pueden ser controlados mediante endoscopia

Long-term follow-up after endoscopic submucosal dissection of colorectal lesions in a Spanish cohort.

INTRODUCTION: ESD in the colon is an increasingly important technique in Western countries. There are few studies that include long term follow-up. AIM: to analyze the long term recurrence free survival rate after ESD and to compare recurrence rates according to different variables. METHODS: this was a prospective observational study of patients with a planned ESD from September 2008 to December 2015. When it was not possible to achieve an ESD, hybrid ESD was performed, either en bloc or piecemeal. Kaplan-Meier survival curves were used to assess the five year local recurrence free survival rate and the recurrence rate. The results were compared according to different factors. RESULTS: of the 89 patients scheduled for ESD who were initially enrolled in the study, 69 were finally included for follow-up. ESD was performed in 31 (45%) patients, KAR in eleven (16%) and pKAR in 27 (39%). The median follow-up was 27 months (range 6-60). The five year disease free survival rate was 81%. The average number of endoscopies needed to eliminate recurrence was two (range 2-7) and no patient required surgery for this reason. The recurrence rate was significantly higher in piecemeal resections vs en bloc resections (27% vs 15%, p = 0.036) and R1 resections vs R0 resections (26% vs 0%, p = 0.034). The presence of affected or unknown lateral margins in en bloc resections without other poor prognosis factors had higher recurrence rates but the difference was not statistically significant (28% vs 0%, p = 0.09). CONCLUSIONS: in our study, the five year disease free survival rate was 81% and no patient required surgery during follow-up. Piecemeal and R1 resections had significantly higher recurrence rates, as well as LM involvement, although this was not statistically significant.

Endoscopic submucosal dissection for gastric epithelial lesions: long-term results in a Spanish cohort.

INTRODUCTION: endoscopic submucosal dissection for gastric lesions (ESD-G) is a technique that allows en-bloc resection of early gastric tumors, with a cure rate similar to that of surgery but lower morbidity and mortality rates. OBJECTIVE: to assess total survival, disease-free survival and relapse rate during the course of disease in a Spanish cohort of patients undergoing ESD-G. MATERIAL AND METHODS: this was a prospective observational study of patients undergoing ESD-G from 2008 to 2015, with a follow-up ranging from six to 60 months. Recurrence at five years was analyzed using Kaplan-Meier curves and the results were compared according to several factors using the log-rank test. These included en-bloc versus piecemeal resection and R0 curative resection versus resection with affected lateral margins (LM+). RESULTS: a total of 35 patients undergoing ESD-G were assessed, with a median follow-up of 33.62 months. Four relapses were identified (11.4%) during this period, of which three were managed with repeat ESD-G. A histological specimen with LM+ was associated with a higher local relapse rate during follow-up (p = 0.06). Piecemeal resections had a higher relapse risk, although no statistically significant differences were identified (p = 0.49). No deaths from gastric cancer occurred and no gastrectomies due to persistent disease were performed during this period. The overall survival rate in our series was 94.3%. CONCLUSIONS: ESD-G in our setting provides high long-term cure rates, while avoiding surgery. These results are similar to those reported by the European series and remain far removed from the cure and relapse rates obtained in Asian cohorts. Local relapse cases may be monitored with endoscopy.

Evaluación prospectiva y controlada de las características técnicas de un nuevo ecoendoscopio de punción frontal / A prospective, controlled assessment of the technical characteristics of a novel forward-viewing echoendoscope

Introducción: la ultrasonografía endoscópica (USE) es una técnica de gran utilidad en el diagnóstico y tratamiento de distintas patologías del tracto digestivo. Objetivo: evaluar de forma prospectiva la utilidad clínica de un nuevo ecoendoscopio de visión frontal (FV-CLA). Métodos: estudio observacional transversal. Todos los pacientes sometidos a una USE durante un periodo de dos meses fueron evaluados para su inclusión en el estudio. Se analizaron de forma sistemática todas las estaciones mediastínicas, perigástricas y periduodenales (evaluando la facilidad de obtener los cortes ultrasonográficos y la calidad de los mismos) y se realizó punción de las lesiones indicadas clínicamente. Resultados: se incluyeron un total de 45 pacientes. La exploración ecoendoscópica pudo ser completada en el 100% de los pacientes, registrándose dos complicaciones menores. La manejabilidad del ecoendoscopio fue catalogada como sobresaliente; la visibilidad global del plano USE, como notable; y tan solo la visualización USE de las estaciones 4L y 5 fue puntuada como insuficiente. La visualización del páncreas y del resto de las estaciones USE fue puntuada como sobresaliente o notable. La facilidad de realizar punción, incluso desde la segunda porción duodenal, fue puntuada como notable o sobresaliente. Conclusión: el FV-CLA permite realizar una exploración completa y de calidad en el tracto digestivo superior, incluyendo punciones. Existen algunas estaciones mediastínicas que parecen poco accesibles para este nuevo aparato. Sería interesante validar la utilidad del FV-CLA en la terapéutica guiada por USE

Introduction: endoscopic ultrasound (EUS) is a highly useful technique for the diagnosis and management of different gastrointestinal (GI) tract conditions. Objective: to prospectively assess the clinical usefulness of a novel forward-viewing echoendoscope (FV-CLA). Methods: this was a cross-sectional observational study. All patients that underwent EUS over a two-month period were considered for the study. All mediastinal, perigastric and periduodenal stations were consistently assessed with a rating from 0 to 10 points with regard to the ease to obtain ultrasonographic sections and the quality of ultrasound images. The identified lesions were punctured when clinically indicated. Results: a total of 45 patients were included. EUS was completed in 100% of patients, with two minor complications recorded. Echoendoscope maneuverability was graded as "A" (9-10 points), overall plane visibility was graded as "B" (7-8 points) and only stations 4L and 5 visualization were graded as "D" (< 7 points). Visualization of the pancreas and the rest of the EUS stations were rated as excellent or very good. The feasibility to perform EUS-FNA, even from the second portion of the duodenum, was graded excellent or very good. Conclusion: the FV-CLA allows a complete, high-quality examination of the upper GI tract, including EUS-FNA punctures. Some mediastinal stations are hardly accessible with this new device. A formal validation of the FV-CLA for EUS-guided therapy would be of interest

Isquemia hepática aguda tras hemorragia digestiva alta por varices esofagogástricas / Acute liver ischaemia after gastro-oesophageal variceal bleeding

INTRODUCCIÓN: La hemorragia digestiva alta por varices esofagogástricas (HDA por VEG) puede desencadenar una isquemia hepática aguda (IHA). El objetivo de este estudio fue analizar la incidencia de IHA tras una HDA por VEG, los factores de riesgo y su mortalidad. PACIENTES Y MÉTODOS: Estudio retrospectivo sobre pacientes cirróticos con HDA por VEG. Se clasificaron en 2 grupos, determinados por el desarrollo o no de una IHA. Definimos IHA como AST y ALT por encima de 10 veces el valor basal, descartando otras causas de hepatitis aguda. El tratamiento inicial estándar fue soporte hemodinámico, endoscopia urgente con ligadura con bandas y/o escleroterapia, somatostatina y antibióticos. En caso de fracaso de estas medidas, se recurrió a la implantación de una derivación portosistémcica percutánea intrahepática (DPPI). Ambos grupos (IHA y no-IHA) fueron comparados. RESULTADOS: Durante un periodo de 5 años, se recogieron 68 pacientes con HDA por VEG. La incidencia de IHA fue del 16,2%. Tras el análisis univariante, los factores asociados con IHA fueron la diabetes mellitus (OR: 7,5; IC: 1,9-29), shock (OR: 8,5; IC: 2,06-34) y la persistencia de la hemorragia (OR: 9, IC: 1,6-49, p = 0,03). En el análisis multivariante solo mostraron significación estadística la diabetes mellitus (OR: 8,61; IC: 1,4-52,5) y el shock (OR: 7,58; IC: 1,26-45,51). La mortalidad del grupo de IHA fue mayor (45%) que en el grupo no-IHA (10,5%) (p = 0,012). CONCLUSIONES: La IHA tras una hemorragia digestiva por VEG en el paciente cirrótico ocurrió en el 16,2%, asociándose con un peor pronóstico y una mortalidad del 45%. Nuestros resultados sugieren que la diabetes mellitus y el shock hipovolémico son factores de riesgo para el desarrollo de IHA. La detección precoz de estos pacientes en riesgo podría por tanto ayudar a prevenir la IHA

INTRODUCTION: Variceal upper gastrointestinal bleeding (UGIB) can trigger acute hypoxic hepatitis (AHH). The aim of this study was to analyse the incidence, associated risk factors and mortality of AHH after variceal UGIB. PATIENTS AND METHODS: Retrospective study of cirrhotic patients with variceal UGIB, classified into 2 groups according to the development of AHH. AHH was diagnosed when AST and ALT reached levels 10 times above the upper limit of normal, after ruling out other causes of hepatitis. The standard initial treatment consisted of haemodynamic support, emergency endoscopy with rubber band ligation, somatostatin and antibiotics. In the case of failure of primary haemostasis, a transjugular intrahepatic portosystemic shunt (TIPS) was implanted. Both groups (AHH and non-AHH) were compared. RESULTS: Sixty-eight cirrhotic patients with variceal UGIB admitted to the gastroenterology department of Hospital Ramón y Cajal between January 2007 and March 2012 were analysed. Eleven of these patients (16.2%) developed AHH. Univariate analysis showed the following items as risk factors: diabetes (OR: 7.5; CI: 1.9-29), shock (OR: 8.5; CI: 2.06-34) and persistent bleeding (OR: 9.0, CI: 1.6-49, P = .03). However, multivariate analysis confirmed only diabetes (OR: 8.61; CI: 1.4-52.5) and shock (OR: 7.58; CI: 1.26-45.51) as risk factors. Mortality rate in the AHH group was 45%, compared to 10.5% in the non-HAA group (P = .012). CONCLUSIONS: AHH after variceal UGIB occurred in 16.2% of cirrhotic patients and was associated with a poorer prognosis, with a mortality rate of 45%. Our findings suggest that diabetes and shock are risk factors for the development of AHH. Early identification of at-risk patients could therefore help prevent AHH
