RESUMO
INTRODUCTION AND AIMS: The outcomes of endoscopic submucosal dissection (ESD) in the esophagus have not been assessed in our country. Our primary aim was to analyze the effectiveness and safety of the technique. MATERIAL AND METHODS: Analysis of the prospectively maintained national registry of ESD. We included all superficial esophageal lesions removed by ESD in 17 hospitals (20 endoscopists) between January 2016 and December 2021. Subepithelial lesions were excluded. The primary outcome was curative resection. We conducted a survival analysis and used logistic regression analysis to assess predictors of non-curative resection. RESULTS: A total of 102 ESD were performed on 96 patients. The technical success rate was 100% and the percentage of en-bloc resection was 98%. The percentage of R0 and curative resection was 77.5% (n=79; 95%CI: 68%-84%) and 63.7% (n=65; 95%CI: 54%-72%), respectively. The most frequent histology was Barrett-related neoplasia (n=55 [53.9%]). The main reason for non-curative resection was deep submucosal invasion (n=25). The centers with a lower volume of ESD obtained worse results in terms of curative resection. The rate of perforation, delayed bleeding and post-procedural stenosis were 5%, 5% and 15.7%, respectively. No patient died or required surgery due to an adverse effect. After a median follow-up of 14months, 20patients (20.8%) underwent surgery and/or chemoradiotherapy, and 9 patients died (mortality 9.4%). CONCLUSIONS: In Spain, esophageal ESD is curative in approximately two out of three patients, with an acceptable risk of adverse events.

La detección del cáncer gástrico precoz y de sus lesiones precursoras constituye un desafío para gran parte de los endoscopistas occidentales. Los cambios morfológicos que se producen en la mucosa gástrica generalmente son sutiles y, por tanto, difíciles de visualizar. En esta revisión se analiza la utilidad de la cromoendoscopia convencional, así como de sus modalidades digitales, y de la endoscopia con magnificación para reconocer y caracterizar estas lesiones.(AU)
Diagnosis of early gastric cancer and its precancerous lesions remains a challenge for great part of western endoscopists. Changes seen in the mucosal pattern are generally subtle and hence difficult to identify. In this article, we will review the usefulness of conventional and virtual chromoendoscopy and magnification endoscopy in the recognition and classification of these lesions.(AU)

BACKGROUND AND AIMS: Underwater EMR (UEMR) is an alternative procedure to conventional EMR (CEMR) to treat large, nonpedunculated colorectal lesions (LNPCLs). In this multicenter, randomized controlled clinical trial, we aimed to compare the efficacy and safety of UEMR versus CEMR on LNPCLs. METHODS: We conducted a multicenter, randomized controlled clinical trial from February 2018 to February 2020 in 11 hospitals in Spain. A total of 298 patients (311 lesions) were randomized to the UEMR (n = 149) and CEMR (n = 162) groups. The main outcome was the lesion recurrence rate in at least 1 follow-up colonoscopy. Secondary outcomes included technical aspects, en bloc resection rate, R0 resection rates, and adverse events, among others. RESULTS: There were no differences in the overall recurrence rate (9.5% UEMR vs 11.7% CEMR; absolute risk difference, -2.2%; 95% CI, -9.4 to 4.9). However, considering polyp sizes between 20 and 30 mm, the recurrence rate was lower for UEMR (3.4% UEMR vs 13.1% CEMR; absolute risk difference, -9.7%; 95% CI, -19.4 to 0). The R0 resection showed the same tendency, with significant differences favoring UEMR only for polyps between 20 and 30 mm. Overall, UEMR was faster and easier to perform than CEMR. Importantly, the techniques were equally safe. CONCLUSIONS: UEMR is a valid alternative to CEMR for treating LNPCLs and could be considered the first option of treatment for lesions between 20 and 30 mm due to its higher en bloc and R0 resection rates.

Endoscopic retrograde cholangiopancreatography (ERCP) placement of biliary stents is the procedure of choice for bile duct strictures. Complications of endoscopic retrograde cholangiopancreatography have a low incidence. Hepatic subcapsular hematoma is uncommon but potentially serious. It is caused by laceration of the bile duct with guidewire or biliary traction during the procedure. Initial management is conservative with supportive measures. In case of hemodynamic instability or superinfection, embolization of the affected branch or even surgery could be performed.

INTRODUCTION: Endoscopic submucosal dissection (ESD) has become the treatment of choice for early gastric malignancies. In recent years, the ESD technique has been implemented in Western countries with increasing use. OBJECTIVES: To describe the results of gastric ESD in a Western country with a low incidence of gastric cancer. PATIENTS AND METHODS: The prospective national registry was conducted over 4 years in 23 hospitals, including 30 endoscopists. Epithelial and subepithelial lesions (SEL) qualified to complete removal with ESD were assessed. The technique, instruments, and solution for submucosal injection varied at the endoscopist's discretion. ESD was defined as difficult when: en-bloc resection was not achieved, had to be converted to a hybrid resection, lasted more than 2 h or an intraprocedural perforation occurred. Additionally, independent risk factors for difficult ESD were analyzed. RESULTS: Two hundred and thirty gastric ESD in 225 patients were performed from January 2016 to December 2019 (196 epithelial and 34 SEL). Most lesions were located in the lower stomach (111; 48.3%). One hundred and twenty-eight (55.6%) ESD were considered difficult. The median procedure time was 105 min (interquartile range [IQR]: 60-150). The procedure time for SEL was shorter than for epithelial lesions (90 min [45-121] vs. 110 min [62-160]; p = 0.038). En-bloc, R0, and curative resection rates were 91.3%, 75.2%, and 70.9%, respectively. Difficult ESD had lower R0 resection rates than ESD that did not meet the difficulty criteria (64.8% and 87.6%; p = 0.000, respectively). Fibrosis and poor maneuverability were independent factors associated with difficult ESD (OR 3.6, 95%CI 1.1-11.74 and OR 5.07, 95%CI 1.6-16.08; respectively). CONCLUSIONS: Although the number of cases is limited, the results of this analysis show acceptable en-bloc and R0 rates in gastric ESD considering the wide variability in experience among the operators. Fibrosis and poor maneuverability were associated with more difficulty in completing ESD.

This position paper, sponsored by the Asociación Española de Gastroenterología [Spanish Association of Gastroenterology], the Sociedad Española de Endoscopia Digestiva [Spanish Gastrointestinal Endoscopy Society] and the Sociedad Española de Anatomía Patológica [Spanish Anatomical Pathology Society], aims to establish recommendations for performing an high quality upper gastrointestinal endoscopy for the screening of gastric cancer precursor lesions (GCPL) in low-incidence populations, such as the Spanish population. To establish the quality of the evidence and the levels of recommendation, we used the methodology based on the GRADE system (Grading of Recommendations Assessment, Development and Evaluation). We obtained a consensus among experts using a Delphi method. The document evaluates different measures to improve the quality of upper gastrointestinal endoscopy in this setting and makes recommendations on how to evaluate and treat the identified lesions. We recommend that upper gastrointestinal endoscopy for surveillance of GCPL should be performed by endoscopists with adequate training, administering oral premedication and use of sedation. To improve the identification of GCPL, we recommend the use of high definition endoscopes and conventional or digital chromoendoscopy and, for biopsies, NBI should be used to target the most suspicious areas of intestinal metaplasia. Regarding the evaluation of visible lesions, the risk of submucosal invasion should be evaluated with magnifying endoscopes and endoscopic ultrasound should be reserved for those with suspected deep invasion. In lesions amenable to endoscopic resection, submucosal endoscopic dissection is considered the technique of choice.

Este documento de posicionamiento, auspiciado por la Asociación Española de Gastroenterología, la Sociedad Española de Endoscopia Digestiva y la Sociedad Española de Anatomía Patológica, tiene como objetivo establecer recomendaciones para el cribado del cáncer gástrico (CG) en poblaciones con incidencia baja, como la española. Para establecer la calidad de la evidencia y los niveles de recomendación se ha utilizado la metodología basada en el sistema GRADE (Grading of Recommendations Assessment, Development and Evaluation). Se obtuvo el consenso entre expertos mediante un método Delphi. El documento evalúa el cribado en población general, individuos con familiares con CG y lesiones precursoras de CG (LPCG). El objetivo de las intervenciones debe ser la reducción de la mortalidad por CG. Se recomienda el uso de la clasificación OLGIM y determinar el subtipo de metaplasia intestinal (MI) para evaluar las LPCG. No se recomienda establecer cribado poblacional endoscópico de CG ni de Helicobacter pylori. Sin embargo, el documento establece una recomendación fuerte para el tratamiento de H.pylori si se detecta la infección, y su investigación y tratamiento en individuos con antecedentes familiares de CG o con LPCG. En cambio, no se recomienda el uso de test serológicos para detectar LPCG. Se sugiere cribado endoscópico únicamente en los individuos con criterios de CG familiar. En cuanto a los individuos con LPCG, solo se sugiere vigilancia endoscópica ante MI extensa asociada a algún factor de riesgo adicional (MI incompleta y/o antecedentes familiares de CG) tras la resección de lesiones displásicas o en pacientes con displasia sin lesión visible tras una endoscopia digestiva alta de calidad con cromoendoscopia

To establish the quality of the evidence and the levels of recommendation, we used the methodology based on the GRADE system (Grading of Recommendations Assessment, Development and Evaluation). We obtained a consensus among experts using a Delphi method. The document evaluates screening in the general population, individuals with relatives with GC and subjects with GC precursor lesions (GCPL). The goal of the interventions should be to reduce GC related mortality. We recommend the use of the OLGIM classification and determine the intestinal metaplasia (IM) subtype in the evaluation of GCPL. We do not recommend to establish endoscopic mass screening for GC or Helicobacter pylori. However, the document strongly recommends to treat H.pylori if the infection is detected, and the investigation and treatment in individuals with a family history of GC or with GCPL. Instead, we recommend against the use of serological tests to detect GCPL. Endoscopic screening is suggested only in individuals that meet familial GC criteria. As for individuals with GCPL, endoscopic surveillance is only suggested in extensive IM associated with additional risk factors (incomplete IM and/or a family history of GC), after resection of dysplastic lesions or in patients with dysplasia without visible lesion after a high quality gastroscopy with chromoendoscopy

INTRODUCTION: the aim of our study was to develop a peroral endoscopic myotomy (POEM) program in our Unit following a two-step sequence: training on animal models and supervision by an experienced endoscopist during the first human cases. METHODS: a single endoscopist experienced in advanced endoscopy was trained in POEM. After observing POEM in referral centers, training was implemented on swine models (preclinical phase). Technical aspects and adverse events were prospectively recorded. A first subset of cases (group A) was compared to a second one (group B) to assess our progression. Finally, POEM was implemented in humans under the supervision of an experienced endoscopist (clinical phase). The outcomes and adverse events were prospectively recorded. RESULTS: during the preclinical phase, 15 POEM procedures were performed on live pigs. Severe adverse events (AE) were less frequent in group B than in group A (12 % vs 57 %, p = 0.07). After nine cases, a plateau of adverse events was reached. During the clinical phase, eleven POEM procedures were performed in patients under expert supervision. Technical and clinical (Eckardt score ≤ 3) success were 100 % and 91 %, respectively (follow-up 3-21 months). In two cases, intervention of an experienced endoscopist was required (cases 2 and 3) because of a difficult orientation at the esophagogastric junction. One mild pneumoperitoneum occurred, with no severe adverse events reported. CONCLUSIONS: training in animal models and supervision by an experienced endoscopist during the first cases could provide the necessary skills to perform POEM safely and effectively.

OBJECTIVES: Most patients with multiple colonic polyps do not have a known genetic or hereditary origin. Our aim was to analyze the presence of inflammatory cytokines and levels of glucose, insulin, and C-reactive protein (CRP) in patients with multiple colonic polyps. METHODS: Eighty-three patients with 10 or more adenomatous or serrated polyps and 53 control people with normal colonoscopy were included. Smoking habits were registered, and glucose, CRP, and basal insulin in the serum/blood were measured. Quantification of IL-2, IL-4, IL-6, IL-10, IL-11, IL-17A, and IL-23 cytokine levels in the serum was performed by a high-sensitivity enzyme-linked immunosorbent assay. RESULTS: Smoking and diabetes were more prevalent in those with colonic polyps than in the control people (67% vs 16%, P = 0.001; 11% vs 2%, P = 0.048). In addition, the cytokine serum levels were higher, i.e., IL-2 (P = 0.001), IL-4 (P = 0.001), IL-6 (P = 0.001), IL-17A (P = 0.001), IL-23 (P = 0.014), and CRP (P = 0.003). Adjusting for sex, smoking, and diabetes in a multivariate analysis, IL-2, IL-4, IL-6, IL-17A, and IL-23 remained independently elevated in cases with multiple polyps. DISCUSSION: These results indicate that immune responses mediated by Th17 cells may be involved in the pathogenesis of multiple colonic polyps.

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

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.

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.

We present a case of intractable dysphagia in a 23-year-old female with type 1 esophageal atresia (EA) and subsequent postsurgical refractory esophageal strictures. The patient was referred due to increasing symptomatology and a slight response to balloon dilations. A biodegradable polydioxanone stent (ELLA) was placed, but this did not relieve the dysphagia. After the sequential placement of two siliconated polypropylene stents (Polyflex(TM), Boston Scientifics), the dysphagia was definitively relieved. To our knowledge, this is the first published case with a full resolution of dysphagia using this strategy in an adult patient
