Location, morphology and invasiveness of lateral spreading tumors in the colorectum differ between two large cohorts from an eastern and western country / La localización, morfología y la infiltración de las lesiones de extensión lateral en colon y recto difieren en dos cohortes extensas de un país oriental y occidental

Background and study aims: Data from Japanese series show that surface morphology of laterally spreading tumors (LST) in the colon identifies lesions with different incidence and pattern of submucosal invasion. Such data from western countries are scarce. We compared clinical and histological features of LST in a western country and an eastern country, with special interest on mucosal invasiveness of LST, and investigated the effect of clinical factors on invasiveness in both countries. Patients and methods: Patients with LST lesions ≥20mm were included from a multicenter prospective registry in Spain and from a retrospective registry from the National Cancer Center Hospital East, Japan. The primary outcome was the presence of submucosal invasion in LST. The secondary outcome was the presence of high-risk histology, defined as high-grade dysplasia or submucosal invasion. Results: We evaluated 1102 patients in Spain and 663 in Japan. Morphological and histological characteristics differed. The prevalence of submucosal invasion in Japan was six-fold the prevalence in Spain (Prevalence Ratio PR=5.66; 95%CI: 3.96, 8.08), and the prevalence of high-risk histology was 1.5 higher (PR=1.44; 95%CI: 1.31, 1.58). Compared to the granular homogeneous type and adjusted by clinical features, granular mixed, flat elevated, and pseudo-depressed types were associated with higher odds of submucosal invasion in Japan, whereas only the pseudo-depressed type showed higher risk in Spain. Regarding high-risk histology, both granular mixed and pseudo-depressed were associated with higher odds in Japan, compared with only the granular mixed type in Spain. Conclusion: This study reveals differences in location, morphology and invasiveness of LST in an eastern and a western cohort.(AU)

Antecedentes y objetivos del estudio: Los datos de series japonesas muestran que la morfología de los tumores de extensión lateral (LST) en el colon identifica lesiones con diferente incidencia y patrón de invasión submucosa. Esta información es escasa en series de países occidentales. Comparamos las características clínicas e histológicas de LST en un país occidental y un país del este, con especial interés en la infiltración de la lesión, e investigamos el efecto de los factores clínicos sobre esta infiltración en ambos países. Pacientes y métodos: Se incluyeron pacientes con lesiones LST ≥20mm de un registro prospectivo multicéntrico en España y de un registro retrospectivo del National Cancer Center Hospital East, Japón. El objetivo primario fue la presencia de invasión submucosa en los LST. El objetivo secundario fue la presencia de histología de alto riesgo, definida como displasia de alto grado o invasión submucosa. Resultados: Evaluamos 1.102 pacientes en España y 663 en Japón. Las características morfológicas e histológicas difirieron. La prevalencia de invasión submucosa en Japón fue 6 veces mayor que la prevalencia en España (razón de prevalencia PR=5,66; IC 95%: 3,96, 8,08), y la prevalencia de histología de alto riesgo fue 1,5 mayor (PR=1,44; IC 95%: 1,31, 1,58). En comparación con el tipo granular homogéneo y ajustado por las características clínicas, los tipos granular mixto, plano elevado y pseudodeprimido se asociaron con mayores probabilidades de invasión submucosa en Japón, mientras que solo el tipo pseudodeprimido mostró mayor riesgo en España. Con respecto a la histología de alto riesgo, tanto el granular mixto como el pseudodeprimido se asociaron con mayores probabilidades en Japón, en comparación con solo el tipo granular mixto en España. Conclusión: Este estudio revela diferencias en la localización, morfología e invasividad de LST en una cohorte oriental y occidental.(AU)

A survey-based analysis on endoscopic quality indicators compliance among Spanish endoscopists.

INTRODUCTION: Endoscopy plays a key role for the diagnosis and management of gastrointestinal disorders. Therefore, quality indicators have been widely proposed in order to optimize endoscopic practice. The aims of this study, promoted by the Spanish Society of Digestive Diseases (SEPD), were to assess the knowledge and compliance to endoscopy quality indicators among Spanish gastroenterologists. METHODS: A 31-questionnaire survey was created based on the endoscopy quality indicators proposed by international guidelines. The survey was distributed among Spanish gastroenterologists who are members of the society. Using only fully completed surveys, a descriptive analysis was performed. Those factors related with a suboptimal quality performance were also investigated. RESULTS: A total of 1,543 surveys were sent and 281 (18.2%) were received completed. Based on the answers obtained, the management of 14 (70%) out of 20 assessed quality indicators was poor: 5 (83.3%) out of 6 pre-procedure items, 7 (58.3%) out of 12 intra-procedure items and 2 (100%) out of 2 post-procedure items. CONCLUSIONS: A significant proportion of Spanish endoscopists do not comply with main endoscopic quality indicators. Factors such as "young" age, public setting, no colorectal cancer screening program and low volume of procedures/week are related to a poorer management of the assessed quality indicators and should be the target for future formative activities.

Absceso paraesofágico: una causa poco frecuente de disfagia en la epidermólisis ampollosa / Paraesophageal abscess: an uncommon cause of dysphagia in epidermolysis bullosa

Introducción La epidermólisis ampollosa engloba un conjunto de enfermedades caracterizadas por la formación de lesiones ampollosas en piel y mucosas ante traumatismos mínimos. La afectación gastrointestinal es casi una constante en la forma distrófica recesiva, siendo el esófago una de las localizaciones más frecuentes de las manifestaciones extracutáneas. El síntoma más común es la disfagia, habitualmente secundaria a la formación de ampollas a este nivel que condicionan la aparición posterior de estenosis esofágicas cicatriciales. Observación clínica Presentamos el caso de una paciente de 48 años con epidermólisis ampollosa distrófica recesiva remitida para estudio de disfagia, con sospecha de estenosis esofágica. La imposibilidad de progresión del gastroscopio pediátrico debido a la aparición de lesiones ampollosas en hipofaringe secundarias al roce del instrumento y la aparente existencia de una compresión extrínseca esofágica nos condujo a realizar una TC cervical para continuar el estudio, la cual mostró una imagen compatible con absceso de localización paraesofágica. Tras valorar el riesgo-beneficio de realizar punción-drenaje endoscópico, optamos por tratamiento conservador consiguiendo buenos resultados y resolución completa de la sintomatología. Conclusiones Se presenta el caso de un absceso paraesofágico asociado a epidermólisis ampollosa, una causa poco común de disfagia en estos pacientes, resuelto con tratamiento antibiótico y esteroideo. En este contexto clínico los procedimientos invasivos, incluyendo los endoscópicos, presentan una elevada tasa de éxito, no obstante y a pesar de su seguridad, es preciso extremar las precauciones, usar la técnica adecuada y considerar otras posibilidades diagnósticas(AU)

Introduction Epidermolysis bullosa encompasses a group of disorders characterized by the development of blisters on the skin and mucous membranes after minimal trauma. Gastrointestinal involvement is almost always present in the recessive dystrophic form, with the esophagus being one of the most frequent sites of extracutaneous manifestations. The most common symptom is dysphagia, which is usually secondary to esophageal blisters that evolve to scar tissue and stenosis. Case report We report the case of a 48-year-old woman with recessive dystrophic epidermolysis bullosa who was referred because of dysphagia, with suspected esophageal stenosis. Pediatric gastroscopy was abandoned due to the development of blistering of the hypopharynx caused by the instrument and the apparent presence of extrinsic esophageal compression. To continue the examination, cervical computed tomography was performed, showing an image compatible with a paraesophageal abscess. After evaluating the risk-benefit ratio of performing endoscopic biopsy-drainage, we decided on conservative treatment, achieving favorable results and complete symptom resolution. Conclusions We describe a case of paraesophageal abscess associated with epidermolysis bullosa, a rare cause of dysphagia in these patients, which was resolved with antibiotic and steroid treatment. In patients with this disease, invasive procedures, including endoscopy, have a high success rate. Despite the safety of these techniques, the utmost precautions should be taken, an appropriate technique should be used, and other diagnostic options should be considered (AU)

Splenic rupture following a diagnostic upper endoscopy.

Complications following endoscopic procedures have been rarely reported and spontaneous rupture of a normal spleen is an exceptional complication following a gastroscopy. This paper reports a case of a spontaneous rupture of a normal spleen following a gastroscopy.
