[Adaptation and Validation for European Portuguese of the Auditory Performance Categories-II and Infant-Toddler Meaningful Auditory Integration Scale for Children with Cochlear Implant]. / Adaptação e Validação para Português Europeu das Escalas Categories Auditory Performance-II e Infant-Toddler Meaningful Auditory Integration Scale em Crianças com Implante Coclear.

INTRODUCTION: The Categories of Auditory Performance II (CAP-II) scale and the Infant-Toddler Meaningful Audit Integration Scale (IT-MAIS) are simple and quick questionnaires that allow assessment of the auditory performance of children with cochlear implant (CI). The aim of this study was to translate, adapt and validate the European Portuguese version of the CAP-II and IT-MAIS scales. METHODS: A total of 85 participants completed the European Portuguese version of the CAP-II and IT-MAIS questionnaires, of which 45 were parents of children with pediatric cochlear implants (9.84 ± 4.22 years) and another 40 were parents of children with normal hearing (8.35 ± 3.56 years). Inter-rater reproducibility, test-retest reproducibility, comparison of study group versus control group results, internal consistency and correlation of the new scales were evaluated. RESULTS: The CAP-II and IT-MAIS scales showed high reliability and reproducibility, respectively, with an intraclass correlation coefficient (ICC) of 0.979 (p < 0.001) and a Spearman's correlation of 0.924 for the CAP-II scale, and an ICC of 0.932 (p < 0.001) and Spearman's correlation coefficient of 0.732 for the IT-MAIS scale. The IT-MAIS and CAP-II versions showed strong internal consistency (Cronbach's α coefficient value of 0.887 for the CAP-II scale and Spearman's positive correlation of 0.677 for the IT-MAIS scale, respectively) and allowed for the differentiation between children with normal hearing and post-implantation children (p = 0.001 and p < 0.001 respectively for each of the scales). There was no association between parental education and the results on the scales (p > 0.05). CONCLUSION: The findings demonstrated that the European Portuguese version of these scales is a valid and reliable tool for assessing auditory performance in European Portuguese-speaking children with hearing loss.

Introdução: As escalas Categories of Auditory Performance II (CAP-II) e Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS) são questionários simples e de rápida aplicação que permitem avaliar o desempenho auditivo de crianças com implante coclear (IC). O objetivo deste estudo foi a tradução, adaptação e validação da versão em português europeu das escalas CAP-II e IT-MAIS. Métodos: Um total de 85 participantes completaram a versão em português europeu dos questionários CAP-II e IT-MAIS, dos quais 45 eram pais de crianças com IC pediátrico (9,84 ± 4,22 anos) e outros 40 eram pais de crianças com audição normal (8,35 ± 3,56 anos). Foi avaliada a reprodutibilidade entre avaliadores, a reprodutibilidade teste-reteste, a comparação dos resultados do grupo de estudo versus grupo de controlo, a consistência interna e a correlação das novas escalas. Resultados: As escalas CAP-II e IT-MAIS apresentaram uma elevada confiabilidade e reprodutibilidade, respetivamente com coeficiente de correlação intraclasse (ICC) de 0,979 (p < 0,001) e correlação de Spearman de 0,924 para a escala CAP-II, e ICC de 0,932 (p < 0,001) e coeficiente de correlação de Spearman de 0,732 para a escala IT-MAIS. As versões do IT-MAIS e do CAP-II apresentaram uma forte consistência interna (valor do coeficiente α de Cronbach de 0,887 para a escala CAP-II e correlação positiva de Spearman de 0,677 para a escala IT-MAIS, respetivamente) e permitem diferenciar entre crianças com audição normal e crianças pós-implantação (p = 0,001 e p < 0,001 respetivamente para cada uma das escalas). Não se verificou existir associação estatisticamente significativa entre a escolaridade e o resultado nas escalas (p > 0,05). Conclusão: A versão em português europeu destas escalas demonstrou ser uma ferramenta válida e confiável na avaliação do desempenho auditivo em crianças falantes de português europeu com deficiência auditiva.

Niti-S Esophageal Mega-Stent: An Emerging Endoscopic Tool with Different Applications in the Management of Surgical Anastomotic Leaks.

Introduction: Anastomotic leak (AL) is a dangerous complication in the early postoperative period after total gastrectomy or esophagectomy being associated with high mortality. Self-expandable metal stents (SEMS) play a significant role in AL management. Only one case report described the use of Mega-Stent in AL setting. The authors report a two-case series with different applications of a Niti-S esophageal Mega-Stent in AL management. Case Report: Case 1 is a 67-year-old male who underwent an esophagectomy due to a squamous cell carcinoma of the distal esophagus. The early postoperative period was complicated with AL and gastropleural fistula. Initially, an OTSC was deployed in the dehiscence but failed to resolve AL. The esophageal Mega-Stent was further placed in-between the esophagus and the bulbus. Post-stenting contrast studies confirmed no further AL.Case 2 is an 86-year-old woman who underwent total gastrectomy with roux-en-y esophagojejunostomy due to a gastric adenocarcinoma, complicated with AL. A partially covered metal stent (PCMS) was placed to cover the anastomosis. Computed tomography confirmed leakage persistence and a second PCMS was deployed, resolving the AL. Several weeks later, both PCMSs presented ingrowth from granulation tissue. An esophageal Mega-Stent was placed (stent-in-stent technique) and 2 weeks later, all stents were removed, with no AL recurrence. Discussion/Conclusion: SEMS placement for AL is a safe, well-established therapeutic technique. Limitations include stent migration and incomplete cover of large AL. Mega-Stent can be an emerging tool for endoscopic AL management.

Introdução: A deiscência anastomótica (DA) é uma complicação grave no pós-operatório precoce da esofagectomia e gastrectomia total, pela sua elevada mortalidade. As próteses metálicas autoexpansíveis (PMAE) desempenham um papel fundamental no tratamento das DA. Na literatura, há apenas um caso descrito sobre a utilização de um Mega-Stent no contexto de DA, que não complicação bariátrica. Os autores reportam uma série de dois casos com diferente aplicação do Mega-Stent esofágico no tratamento de DA. Descrição do caso: Caso 1: Homem de 67 anos, submetido a esofagectomia por carcinoma epidermóide do esófago distal. O período pós-operatório precoce foi complicado de DA com fístula gastro-pleural. Inicialmente foi colocado um clip OTSC no orifício da deiscência com insucesso técnico e clínico, sendo posteriormente utilizado o Mega-Stent, posicionado desde o esófago até ao bulbo duodenal. Estudos contrastados posteriores confirmaram resolução da DA. Caso 2: Mulher de 86 anos, submetida a gastrectomia total com reconstrução em Y-Roux e esofagojejunostomia por adenocarcinoma gástrico, complicada de DA. Neste contexto foi colocada uma PMAE parcialmente coberta (PMAE-PC) sobre a área da anastomose. A tomografia computorizada subsequente demonstrou persistência de extravasamento. Foi colocada uma segunda PMAE-PC, com posterior resolução da DA. Semanas depois, ambas as PMAE-PC apresentavam tecido de granulação nos topos, tendo sido colocado o Mega-Stent (técnica stent-in-stent) e decorridas duas semanas, todas as próteses foram facilmente extraídas, confirmando-se sucesso no tratamento da DA. Discussão/conclusão: A utilização de PMAE nas DA constitui uma técnica terapêutica segura e bem estabelecida, contudo passível de apresentar limitações tais como a migração ou incapacidade de cobrir totalmente DA de maiores dimensões. O Mega-Stent esofágico pode constituir uma ferramenta útil na terapêutica endoscópica destes doentes.

Duodenal angiolipoma: a rare tumor causing recurrent upper gastrointestinal bleeding.

Duodenal angiolipoma is a rare adipocytic tumor, with non-specific symptoms precluding an early diagnosis. We present a case of a 67-year-old female admitted due to upper gastrointestinal bleeding. The upper endoscopy and endoscopic ultrasound evaluation showed a subepithelial lesion in the third portion of the duodenum. Endoscopic excision was performed using a standard polypectomy technique after endoloop placement. Histopathology was compatible with duodenal angiolipoma. The authors highlight duodenal angiolipoma as a rare adipocytic tumor potentially causing gastrointestinal bleeding, which can be safely treated with endoscopic excision.

Metastatic melanoma: an uncommon cause of upper gastrointestinal bleeding.

Melanoma gastrointestinal metastases are rare and represent a late stage of malignant disease with the jejunum and ileum being the most common locations followed by stomach, colon and duodenum. We present a case of a patient with past history of cutaneous melanoma treated twelve years before, in remission. The patient developed upper gastrointestinal bleeding due to metastatic melanoma in the duodenum.

EUS-guided hepaticogastrostomy in multimetastatic liver disease - an effective approach for biliary drainage that may complement ERCP.

A 36-year-old male was diagnosed with a metastasized colon adenocarcinoma causing obstructive jaundice. Magnetic resonance cholangiography showed a dominant lesion causing hilar stenosis. The patient was submitted to endoscopic retrograde cholangiopancreatography (ERCP), nevertheless it was just possible to place a single uncovered self-expandable metallic stent (SEMS) in the right lobe. Although cholestasis significantly improved, safe levels for oncologic therapy were not reached. EUS-guided hepaticogastrostomy was proposed to complement ERCP biliary drainage. Using a forward-viewing echoendoscope and a transgastric approach, EUS-guided puncture of a dilated left intrahepatic duct at segment III was accomplished with a 19G needle (EchoTip ProCore®) that allowed passage of a 0.035 guidewire. A 6F cystotome and biliary dilators (5Fr+8.5Fr) were used for needle tract dilation. A partially-covered SEMS (GIOBOR™ 8x100mm) could be deployed under endoscopic and fluoroscopic control, being placed 3cm inside the gastric lumen. No associated complications were observed after the procedure.

Long-Term Intestinal Failure and Home Parenteral Support: A Single Center Experience.

Introduction: Home parenteral nutrition (HPN) and/or home parenteral hydration (HPH) are the gold-standard treatment for patients with long-term intestinal failure (IF). The authors aimed to assess the impact of HPN/HPH on nutritional status and survival of long-term IF patients, as well as HPN/HPH-related complications. Methods: This was a retrospective study including IF patients under HPN/HPH followed in a single large tertiary Portuguese hospital. The data collected included demographics, underlying conditions, anatomical characteristics, type and duration of parenteral support, IF functional, pathophysiological, and clinical classifications, body mass index (BMI) at the beginning and end of follow-up, complications/hospitalizations, current patient status (deceased, alive with HPN/HPH, and alive without HPN/HPH), and cause of death. Survival after HPN/HPH beginning, until death or August 2021, was recorded in months. Results: Overall 13 patients were included (53.9% female, mean age 63.46 years), and 84.6% of patients presented type III IF and 15.4% type II. Short bowel syndrome caused 76.9% of IF. Nine patients received HPN and 4 HPH. Eight patients (61.5%) were underweight at the beginning of HPN/HPH. At the end of follow-up, 4 patients were alive without HPN/HPH, 4 maintained HPN/HPH, and 5 died. All patients improved their BMI (mean initial BMI 18.9 vs. 23.5 at the end, p < 0.001). Eight patients (61.5%) were hospitalized due to catheter-related complications, mainly infectious (mean hospitalization episodes 2.25, mean hospital stay of 24.5 days). No deaths were related to HPN/HPH. Conclusion: HPN/HPH significantly improved IF patients' BMI. HPN/HPH-related hospitalizations were common, however causing no deaths, reinforcing that HPN/HPH is an adequate and safe therapy for long-term IF patients.

Introdução: A nutrição parentérica domiciliária (NPD) e/ou a hidratação parentérica domiciliária (HPD) constituem o tratamento gold-standard para doentes com falência intestinal (FI) crónica. O objetivo do presente estudo foi avaliar o impacto da NPD/HPD no status nutricional e sobrevivência dos doentes com FI crónica, bem como as complicações relacionadas à NPD/HPD. Métodos: Estudo retrospetivo, incluindo doentes com FI sob NPD/HPD, seguidos num hospital terciário em Portugal. Informação recolhida para cada doente: dados demográficos, patologia de base, características anatómicas, tipo e duração do suporte parentérico, classificação funcional, fisiopatológica e clínica da FI, índice de massa corporal (IMC) no início e final do seguimento, complicações/hospitalizações, estado atual do doente (falecido, vivo sob NPD/HPD e vivo sem NPD/HPD) e causa de morte. A sobrevida após início da NPD/HPD foi calculada em meses, até à data da morte ou agosto de 2021. Resultados: Incluídos 13 doentes (53.9% do sexo feminino, idade média 63.46 anos), 84.6% com FI tipo III e 15.4% com FI tipo II. A síndrome do intestino curto foi causa de 76.9% das FI. Nove doentes foram tratados com NPD e 4 com HPD. Oito doentes (61.5%) apresentavam IMC baixo no início da NPD/HPD. No final do seguimento, 4 doentes estavam vivos sem NPD/HPD, 4 mantinham NPD/HPD e 5 faleceram. Todos os doentes melhoraram significativamente o seu IMC (IMC médio no início do seguimento 18.9kg/m2 vs 23.5kg/m2 no final, p<0.001). Oito doentes (61.5%) tiveram de ser hospitalizados devido a complicações relacionadas com o cateter, sobretudo de causa infeciosa (número médio de hospitalizações por doente 2.25, duração média de internamento 24.5 dias). Não houve mortes relacionadas com a NPD/ HPD. Conclusão: A NPD/HPD melhorou significativamente o IMC dos doentes com FI. As hospitalizações relacionadas com a NPD/HPD foram comuns, contudo não causaram mortes, reforçando o facto que a NPD/HPD é uma terapêutica segura e adequada para doentes com FI crónica.

Prolonged Fasting Induces Histological and Ultrastructural Changes in the Intestinal Mucosa That May Reduce Absorption and Revert after Enteral Refeeding.

Background: Malnutrition is usual in patients referred for endoscopic gastrostomy (PEG). Refeeding syndrome is rarely observed in PEG-fed patients, which could possibly be associated with reduced absorption induced by prolonged starvation. Objective: In patients submitted to PEG after a significant period of fasting, the present study aims to: 1. evaluate the histological/ultrastructural initial changes in the intestinal mucosa, potentially associated with reduced absorption, and 2. assess if these changes could reverse with enteral refeeding. Methods: The present study is an observational, prospective, controlled study. Adult patients with ingestion below 50% of daily needs for at least one month and/or diagnosis of malnutrition were enrolled. Duodenal biopsies were taken at baseline and after 3-6 months of PEG feeding, which then underwent histological/ultrastructural analysis. Random healthy individuals were used as controls. Results: A total of 30 patients (16 men/14 women) aged 67.1 ± 13.5 years were included. Malnutrition was found in 40% of patients. Approximately 14 patients completed follow-up during both periods (46.7%). At baseline: duodenal mucosal atrophy was evident in three patients (10%); the median villi length (MVL) was 0.4 mm (0.25-0.6 mm), with it being shorter than the controls, which was 0.6 mm (0.4-0.7 mm) (p = 0.006); ultrastructural changes included focal shortening, bending, and disruption of enterocyte microvilli, the presence of citoplasmatic autophagic vacuoles, dilation and vesiculation of the smooth endoplasmic reticulum, and the presence of dilated intercellular spaces with basement membrane detachment. After refeeding, most patients displayed normal histology (92.9%) and increase MVL (p < 0.001), ultrastructural changes disappeared, and enterocytes resumed a normal appearance, although retaining scarce, small, dense bodies in apical regions from the evolution of previous autophagy. Conclusions: Prolonged fasting induces histological and ultrastructural changes in the intestinal mucosa that may reflect impaired absorption in the early post-PEG period. These changes were reverted after refeeding with enteral nutrition.

Pyogenic Liver Abscess and Delayed Massive Gastrointestinal Bleeding Following Endoscopic Retrograde Cholangiopancreatography (ERCP): Association of Two Rare Complications.

A liver abscess (LA) is the most common type of visceral abscess. While biliary tract disorders are its most common etiology, clinicians should also consider less frequent causes such as iatrogenic complications due to certain interventions. One of these unusual causes is related to endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (ES), a usually safe procedure that carries some risk of complications. We present the case of a 71-year-old female with a history of choledocholithiasis who underwent ERCP with ES without any immediate complications; she was discharged after 24 hours and readmitted three days later to the emergency room with fever and abdominal pain. An abdominal CT showed a liver abscess. Blood cultures were positive for Escherichia coli, Streptococcus anginosus, and Enterococcus faecalis, and the patient was started on directed antibiotic therapy with ampicillin, benzylpenicillin, and metronidazole. On day 17, due to hematochezia with hemodynamic instability, an urgent upper gastrointestinal endoscopy was performed, which revealed late post-ES bleeding, refractory to conventional endoscopic therapy. An ERCP was performed to control the bleeding by using a biliary fully covered self-expandable metal stent (FCSEMS), which was removed four weeks later. The follow-up CT showed a significant reduction of LA and the patient was discharged. This case highlights the association of two uncommon complications of ERCP: a LA and a major late post-ES bleeding. Clinicians should maintain a high index of suspicion for these complications in daily practice.

[Translation, Cultural Adaptation and Contributions to the Validation of the Nijmegen Cochlear Implant Questionnaire (NCIQ) for European Portuguese]. / Tradução, Adaptação Cultural e Contributos para a Validação da Escala Nijmegen Cochlear Implant Questionnaire (NCIQ) para o Português Europeu.

INTRODUCTION: The Nijmegen Cochlear Implant Questionnaire (NCIQ) scale uses a simple and easily administered questionnaire to evaluate the adaptation of individuals to their cochlear implants. The aim of this study was to validate the NCIQ for European Portuguese, through its translation and cultural adaptation. It also presents the evaluation of reproducibility and the description of the results of this questionnaire in patients using IC. MATERIAL AND METHODS: Fifty postlingually deaf adult multichannel cochlear implant users (uni- or bilateral) participated in the study. Participants used the cochlear implant for at least 12 months and were patients of the Department of Otolaryngology at the Egas Moniz Hospital in Lisbon. Permission, as well the guidelines for translation, were obtained from the authors of the scale. Translation and cultural adaptation were carried out, in addition to the evaluation of reproducibility and internal consistency. RESULTS: The participants were 44.0% male and 56.0% female, aged between 20 and 79 years (55.50 ± 15.69). The results of the study showed an overall level of satisfaction of 65.07 among cochlear implants users. The level of satisfaction of the subdomains was 64.40 in basic sound perception, 71.35 in advanced sound perception, 57.91 in speech production, 59.05 in self-esteem, 69.75 in activity and 68.50 in social functioning. Internal consistency (Cronbach α score = 0.96) and test-retest reliability coefficients proved to be strong. Furthermore, the questionnaire's overall and subdomains average scores did not differ significantly from the results obtained with the original scale. CONCLUSION: This adaptation of the NCIQ questionnaire for European Portuguese should be considered a good tool to evaluate the level of satisfaction of cochlear implant users and, so far, it is the only scale in this field validated for application in the Portuguese population.

Material e Métodos: Participaram no estudo 50 adultos utilizadores de implante coclear multicanal (uni ou bilateral), com surdez pós-lingual, no mínimo com 12 meses de uso, implantados e seguidos no serviço de Otorrinolaringologia do Hospital Egas Moniz em Lisboa. Foram pedidas a autorização e as normas para a tradução do questionário aos autores da escala e realizada a tradução e retroversão do questionário, a adaptação cultural, e a avaliação da reprodutibilidade e da consistência interna. Resultados: Os participantes eram 44,0% do género masculino e 56,0% do feminino, com idades compreendidas entre os 20 e os 79 anos (55,50 ± 15,69). Os resultados obtidos neste estudo demonstraram um nível de satisfação global de 65,07 nos utilizadores de implantes cocleares. O nível de satisfação dos subdomínios foi de 64,40 na perceção básica do som, 71,35 na perceção avançada do som, 57,91 na produção da fala, 59,05 na autoestima, 69,75 na atividade e 68,50 nas interações sociais. A versão traduzida do questionário NCIQ apresentou uma boa consistência interna para todos os domínios existentes no questionário (α de Cronbach = 0,96). Verificou-se também uma boa reprodutibilidade inter-pesquisadores. Para a pontuação global e das subescalas do questionário, os resultados médios obtidos demonstraram não haver diferenças significativas com a escala original. Conclusão: A adaptação do Nijmegen Cochlear Implant Questionnaire para Português Europeu deve ser considerada um bom instrumento para a avaliação da satisfação dos utilizadores de implantes cocleares e é, até ao momento, a única escala neste domínio validada para aplicação na população portuguesa.

Histological Inflammation in the Endoscopically Uninflamed Mucosa is Associated With Worse Outcomes in Limited Ulcerative Colitis.

BACKGROUND: The Montreal classification categorizes patients with ulcerative colitis (UC) based on their macroscopic disease extent. Independent of endoscopic extent, biopsies through all colonic segments should be retrieved during index colonoscopy. However, the prognostic value of histological inflammation at diagnosis in the inflamed and uninflamed regions of the colon has never been assessed. METHODS: This was a multicenter retrospective cohort study of newly diagnosed patients with treatment-naïve proctitis and left-sided UC. Biopsies from at least 2 colonic segments (endoscopically inflamed and uninflamed mucosa) were retrieved and reviewed by 2 pathologists. Histological features in the endoscopically inflamed and uninflamed mucosa were scored using the Nancy score. The primary outcomes were disease complications (proximal disease extension, need for hospitalization or colectomy) and higher therapeutic requirements (need for steroids or for therapy escalation). RESULTS: Overall, 93 treatment-naïve patients were included, with a median follow-up of 44 months (range, 2-329). The prevalence of any histological inflammation above the endoscopic margin was 71%. Proximal disease extension was more frequent in patients with histological inflammation in the endoscopically uninflamed mucosa at diagnosis (21.5% vs 3.4%, P = 0.04). Histological involvement above the endoscopic margin was the only predictor associated with an earlier need for therapy escalation (adjusted hazard ratio, 3.69; 95% confidence interval, 1.05-13.0); P = 0.04) and disease complications (adjusted hazard ratio, 4.79; 95% confidence interval, 1.10-20.9; P = 0.04). CONCLUSIONS: The presence of histological inflammation in the endoscopically uninflamed mucosa at the time of diagnosis was associated with worse outcomes in limited UC.

NOBLADS-External Validation of a Risk Scoring System for Severe Acute Lower Gastrointestinal Bleeding.

BACKGROUND: Acute lower gastrointestinal bleeding is a common cause of hospital admission. NOBLADS is a lower gastrointestinal bleeding clinical risk score. OBJECTIVE: This study aimed to externally validate NOBLADS in predicting severe acute lower gastrointestinal bleeding and clinical outcome. DESIGN: Observational retrospective study. SETTING: This study was performed in a single large tertiary hospital. PATIENTS: Patients who were admitted with acute lower gastrointestinal bleeding during a 15-month period and underwent endoscopic evaluation were included. Patients with chronic lower gastrointestinal bleeding or acute lower gastrointestinal bleeding who were admitted for other conditions were excluded. MAIN OUTCOME MEASURES: Primary outcome was acute severe lower gastrointestinal bleeding (classified as severe if requires transfusion of >2 units of packed red blood cells and/or produces a >20% hematocrit fall). Secondary outcomes: red blood cells requirement, therapeutic intervention and hospital stay duration. NOBLADS score was applied to all patients. Its accuracy to predict acute severe bleeding and secondary outcomes were studied using receiver operating characteristic analysis. RESULTS: A total of 173 patients (50.3% males, age 69 ± 17 years) were included. The most common lower gastrointestinal bleeding etiologies were diverticular bleeding (18.5%) and ischemic colitis (15.6%). Fifty patients (28.9%) presented criteria for severe bleeding and 33 patients required instrumental intervention: endoscopic (n = 28), surgical (n = 4), and radiologic (n = 1) therapy. NOBLADS score was significantly different according with acute lower gastrointestinal bleeding causes (p < 0.001) and accurately predicted severe bleeding (area under the receiver operating characteristic curve 0.923 ± 0.018 (p < 0.001)). NOBLADS ≥2 detected acute severe lower gastrointestinal bleeding with 100% sensitivity/62.4% specificity, identifying the need for higher red blood cells requirement (3.6 vs 0.08, p < 0.001), therapeutic intervention (38% vs 13%, p < 0.001), and longer hospital stay (12.8 vs 3 days, p < 0.001). LIMITATIONS: Unicenter retrospective study; number of unprepared sigmoidoscopies/left side colonoscopies; comparison between NOBLADS and other scoring systems was not performed. CONCLUSION: NOBLADS is a practical, highly accurate tool and predicts the need of in-hospital management, early colonoscopy, red blood cells transfusion, and longer hospital stay in patients admitted with acute lower gastrointestinal bleeding.

ANTECEDENTES: La hemorragia digestiva baja aguda es causa común de admisión hospitalaria. NOBLADS es una puntuación de riesgo clínico de hemorragia gastrointestinal baja. OBJETIVO: Este estudio tuvo como objetivo validar externamente NOBLADS en la predicción de hemorragia digestiva baja aguda grave y sus resultados clínicos. DISEO: Estudio observacional retrospectivo. AJUSTE: Realizado en un gran hospital terciario. PACIENTES: Se incluyeron todas aquellas personas ingresados con hemorragia digestiva baja aguda durante un período de 15 meses y que fueron sometidos a evaluación endoscópica. Se excluyó la hemorragia digestiva baja crónica o la hemorragia digestiva baja aguda en pacientes ingresados por otras afecciones. PRINCIPALES MEDIDAS DE RESULTADO: El resultado pricipal fue la hemorragia digestiva baja grave aguda (clasificada como grave si requiere >2 transfusiones de glóbulos rojos y / o produce una caída del hematocrit >20%). Las medidas de resultados secundarias fueron: requerimiento de glóbulos rojos, intervención terapéutica y duración de la estancia hospitalaria. Se aplicó la puntuación NOBLADS a todos los pacientes. Se estudió su precisión para predecir la hemorragia aguda grave y los resultados secundarios mediante análisis ROC. RESULTADOS: Se incluyeron 173 pacientes (50,3% varones, edad 69 ± 17 años). La etiología de hemorragia digestiva baja más frecuentes fueron: la hemorragia de orígen diverticular (18,5%) y la colitis isquémica (15,6%). 50 pacientes (28,9%) presentaron criterios de sangrado severo y 33 pacientes requirieron intervención instrumental: terapia endoscópica (n = 28), quirúrgica (n = 4), radiológica (n = 1). La puntuación NOBLADS fue significativamente diferente según las causas de hemorragia digestiva baja aguda (p <0,001), siendo precisa para predecir hemorragia grave (AUC 0,923 ± 0,018 (p <0,001). NOBLADS ≥2 detectó hemorragia digestiva baja aguda grave con 100% de sensibilidad / 62,4 % de especificidad, identificando la necesidad de mayor requerimiento de glóbulos rojos (3.6 vs 0.08, p <0.001), intervención terapéutica (38% vs 13%, p <0.001) y estadía hospitalaria más prolongada (12.8 vs 3 días, p <0.001). LIMITACIONES: Estudio retrospectivo Unicentrico; número de sigmoidoscopias / colonoscopias del lado izquierdo no preparadas; no se realizó comparación entre NOBLADS y otros sistemas de puntuación. CONCLUSIN: NOBLADS es una herramienta práctica y altamente precisa que predice la necesidad de manejo hospitalario, colonoscopia precoz, transfusión de glóbulos rojos y estadía hospitalaria más prolongada en pacientes ingresados con hemorragia digestiva baja aguda.

Endoscopic gastrostomy for nutritional support in post-stroke dysphagia / Gastrostomía endoscópica para el soporte nutricional en la disfagia posterior a un accidente cerebrovascular

Introduction: persistent dysphagia affects 15 % of stroke patients and contributes to malnutrition, aspiration, and death. This study aimed to characterize patients with post-stroke dysphagia who underwent percutaneous endoscopic gastrostomy (PEG), and to assess the impact of PEG feeding on nutritional status and outcome. Methods: an observational and retrospective study using records from patients with post-stroke dysphagia who underwent PEG. Body mass index (BMI), serum albumin, transferrin, and cholesterol were recorded at the time of PEG insertion (T0) and 3 months later (T3). The evolution of these parameters was analyzed and compared to survival. Results: we obtained data from 158 patients (53.2 % males) with a median age of 75 years. Most strokes were ischemic (n = 135, 85.4 %). Median time between stroke and PEG was 2 months. Median survival after gastrostomy was 16 months. At admission, 41.6 % of patients had low BMI, 62.3 % low albumin, 68.6 % low transferrin, and 59.6 % low cholesterol levels. The prevalence of low albumin and low transferrin was higher in the patients who underwent PEG more than 2 months after stroke. A significant increase in albumin and transferrin, and a normalization of cholesterol levels was observed after 3 months of PEG feeding. Mortality was 12.9 %, 27.7 %, and 40 % at 1, 3, and 12 months, respectively. Survival was lower in patients with low albumin, transferrin or total cholesterol at admission. Conclusions: the prevalence of malnutrition is high among patients with post-stroke dysphagia. PEG feeding improves albumin, transferrin, and cholesterol levels. Early post-PEG mortality is high and must be considered on an individual basis. (AU)

Introducción: la disfagia persistente afecta al 15 % de los pacientes con accidente cerebrovascular (AVC) y contribuye a producir desnutrición, aspiración y muerte. Este estudio tuvo como objetivo caracterizar a los pacientes con disfagia post-AVC sometidos a gastrostomía endoscópica percutánea (PEG) y evaluar el impacto de la alimentación con PEG sobre el estado nutricional. Métodos: estudio observacional y retrospectivo que utiliza registros de pacientes con disfagia post-AVC sometidos a PEG. El índice de masa corporal (IMC) y los niveles de albúmina, transferrina y colesterol séricos se registraron en el momento de la inserción de la PEG (T0) y 3 meses después (T3). La evolución de estos parámetros se analizó y comparó con la supervivencia. Resultados: se obtuvieron datos de 158 pacientes (53,2 % hombres) con una edad media de 75 años. La mayoría de los AVC fueron isquémicos (n = 135, 85,4 %). El tiempo medio entre el AVC y la PEG fue de 2 meses. La supervivencia media después de la gastrostomía fue de 16 meses. Al ingreso, el 41,6 % de los pacientes presentaba un IMC bajo, el 62,3 % un nivel bajo de albúmina, el 68,6 % un nivel bajo de transferrina y el 59,6 % un nivel bajo de colesterol. La prevalencia de los niveles bajos de albúmina y de transferrina fue mayor en los pacientes que se sometieron a la PEG más de 2 meses después del AVC. Se observó un aumento significativo de la albúmina y la transferrina, y una normalización de los niveles de colesterol, después de 3 meses de alimentación con PEG. La mortalidad fue del 12,9 %, 27,7 % y 40 % a 1, 3 y 12 meses, respectivamente. La supervivencia fue menor en los pacientes con nivel bajo de albúmina, transferrina o colesterol total al ingreso. Conclusiones: la prevalencia de la malnutrición es alta entre los pacientes con disfagia post-AVC. La alimentación con PEG mejora los niveles de albúmina, transferrina y colesterol. La mortalidad temprana post-PEG es alta y debe considerarse de forma individual. (AU)

Endoscopic gastrostomy for nutritional support in post-stroke dysphagia.

INTRODUCTION: Introduction: persistent dysphagia affects 15 % of stroke patients and contributes to malnutrition, aspiration, and death. This study aimed to characterize patients with post-stroke dysphagia who underwent percutaneous endoscopic gastrostomy (PEG), and to assess the impact of PEG feeding on nutritional status and outcome. Methods: an observational and retrospective study using records from patients with post-stroke dysphagia who underwent PEG. Body mass index (BMI), serum albumin, transferrin, and cholesterol were recorded at the time of PEG insertion (T0) and 3 months later (T3). The evolution of these parameters was analyzed and compared to survival. Results: we obtained data from 158 patients (53.2 % males) with a median age of 75 years. Most strokes were ischemic (n = 135, 85.4 %). Median time between stroke and PEG was 2 months. Median survival after gastrostomy was 16 months. At admission, 41.6 % of patients had low BMI, 62.3 % low albumin, 68.6 % low transferrin, and 59.6 % low cholesterol levels. The prevalence of low albumin and low transferrin was higher in the patients who underwent PEG more than 2 months after stroke. A significant increase in albumin and transferrin, and a normalization of cholesterol levels was observed after 3 months of PEG feeding. Mortality was 12.9 %, 27.7 %, and 40 % at 1, 3, and 12 months, respectively. Survival was lower in patients with low albumin, transferrin or total cholesterol at admission. Conclusions: the prevalence of malnutrition is high among patients with post-stroke dysphagia. PEG feeding improves albumin, transferrin, and cholesterol levels. Early post-PEG mortality is high and must be considered on an individual basis.

INTRODUCCIÓN: Introducción: la disfagia persistente afecta al 15 % de los pacientes con accidente cerebrovascular (AVC) y contribuye a producir desnutrición, aspiración y muerte. Este estudio tuvo como objetivo caracterizar a los pacientes con disfagia post-AVC sometidos a gastrostomía endoscópica percutánea (PEG) y evaluar el impacto de la alimentación con PEG sobre el estado nutricional. Métodos: estudio observacional y retrospectivo que utiliza registros de pacientes con disfagia post-AVC sometidos a PEG. El índice de masa corporal (IMC) y los niveles de albúmina, transferrina y colesterol séricos se registraron en el momento de la inserción de la PEG (T0) y 3 meses después (T3). La evolución de estos parámetros se analizó y comparó con la supervivencia. Resultados: se obtuvieron datos de 158 pacientes (53,2 % hombres) con una edad media de 75 años. La mayoría de los AVC fueron isquémicos (n = 135, 85,4 %). El tiempo medio entre el AVC y la PEG fue de 2 meses. La supervivencia media después de la gastrostomía fue de 16 meses. Al ingreso, el 41,6 % de los pacientes presentaba un IMC bajo, el 62,3 % un nivel bajo de albúmina, el 68,6 % un nivel bajo de transferrina y el 59,6 % un nivel bajo de colesterol.

Se observó un aumento significativo de la albúmina y la transferrina, y una normalización de los niveles de colesterol, después de 3 meses de alimentación con PEG. La mortalidad fue del 12,9 %, 27,7 % y 40 % a 1, 3 y 12 meses, respectivamente. La supervivencia fue menor en los pacientes con nivel bajo de albúmina, transferrina o colesterol total al ingreso. Conclusiones: la prevalencia de la malnutrición es alta entre los pacientes con disfagia post-AVC. La alimentación con PEG mejora los niveles de albúmina, transferrina y colesterol. La mortalidad temprana post-PEG es alta y debe considerarse de forma individual.

A unique case of bleeding from esophageal varices as the first sign of essential thrombocythemia.

Upper gastrointestinal bleeding (UGIB) is a common cause of hospital admission and variceal hemorrhage is responsible for many UGIB cases. Esophageal and gastric varices are caused by portal hypertension (PHT), mostly due to liver cirrhosis. Portal vein thrombosis (PVT) is an important cause of non-cirrhotic PHT and can be associated with several diseases, including myeloproliferative disorders such as essential thrombocythemia (ET). PVT may become apparent due to complications of PHT, including variceal bleeding (VB). We report the case of a 43-year-old male admitted with esophageal VB. Etiologic work-up for chronic liver disease was negative and abdominal magnetic resonance imaging revealed chronic PVT with cavernous transformation and a non-cirrhotic liver. JAK2 mutation was found, and the bone-marrow biopsy was consistent with ET, without peripheral blood alterations. This is a unique case of ET diagnosed in a variceal bleeding setting, remembering the necessity for high clinical suspicion.

A Unique Case of Recurrent Upper Gastrointestinal Bleeding Caused by Two Metachronous Dieulafoy's Lesions: The Role of EUS Evaluation.

INTRODUCTION: Dieulafoy's lesion (DL) is a rare but important cause of acute, severe, life-threatening, and recurrent upper gastrointestinal bleeding (UGIB). It is frequently difficult to diagnose DL with upper GI endoscopy (UGIE), and endoscopic ultrasonography (EUS) may be valuable. There are only 2 reported bleeding cases caused by two synchronous DL but no reported cases of two metachronous DL. CASE REPORT: A 28-year-old healthy male presented with acute severe UGIB. UGIE was inconclusive. Systematic EUS mapping identified a gastric DL. After several attempts of EUS-guided hemostasis, DL was marked using a through-the-scope clip and the patient underwent successful transcatheter arterial embolization (TAE). Three years later, a new severe UGIB episode was caused by a second gastric DL in a different location, which was identified and marked by EUS and further successfully treated through TAE. The patient maintained follow-up without evidence of further bleeding. DISCUSSION/CONCLUSION: The authors report a unique case of severe, recurrent UGIB caused by two metachronous gastric DL lesions. The importance of systematic EUS scanning for diagnosis, treatment, and follow-up of DL is emphasized, as well as the potential influence in the outcome of other techniques like angiographic embolization.

INTRODUÇÃO: a lesão de Dieulafoy (LD) é uma causa rara de hemorragia digestiva alta (HDA), podendo causar hemorragia grave e recorrente. Diagnosticar esta lesão através da endoscopia digestiva alta (EDA) pode ser um desafio e a ecoendoscopia (EUS) é uma ferramenta muito útil. Há apenas dois casos reportados de hemorragia digestiva por duas LD síncronas, mas não há casos descritos de doentes com duas HDA por LD metácronas. CASO CLÍNICO: homem de 28 anos, saudável, admitido por HDA grave, EDA inconclusiva. Mapeamento gástrico sistemático por EUS identificou LD gástrica. Várias tentativas ineficazes de hemostase endoscópica e guiada por EUS. Marcação da LD com clip guiada por EUS e referenciação para embolização arterial (EA), bem-sucedida. Três anos depois, nova HDA grave devido a uma segunda LD gástrica, em topografia diferente, diagnosticada e marcada com clip por EUS, tratada com EA. Até à data sem recidiva. DISCUSSÃO/CONCLUSÃO: relatamos um caso único de HDA grave recorrente, causada por duas LD gástricas metácronas. Salienta-se a importância de uma avaliação sistemática por EUS no diagnóstico destas lesões. Salientamos o papel desta técnica no diagnóstico e tratamento das LD e possibilidade de articulação com outras técnicas, nomeadamente a EA.
