ABSTRACT

Abstract We present a rare case of hypertrophic gastropathy associated with protein loss. A 35-year-old man was hospitalized for bowel habit changes, abdominal pain, generalized edema and symptomatic anemia. Pertinent laboratory findings included iron deficiency anemia (Hb 6.7g/dl, ferritin 5 ng/ml) and marked hypoalbuminemia (albumin 2.5 g/dl). Endoscopic biopsy samples of giant gastric folds observed along the greater gastric curvature revealed foveolar hyperplasia and significant parietal cell loss. Endoscopic ultrasonography showed gastric parietal thickening with preserved architecture and normal gastric wall layers. Menetrier disease was diagnosed and the patient treated with cetuximab, a monoclonal antibody that inhibits ligand binding of trans forming growth factor alpha (TGFa), preventing gastric mucosa cell proliferation. After twelve months of treatment, the patient referred symptoms improvement, and gastric biopsy levels of the proliferation marker protein Ki-67 had decreased.


Resumen Presentamos un caso infrecuente de gastropatía hipertrófica asociada a pérdida de proteínas. Un hombre de 35 años fue hos pitalizado por cambios en los hábitos intestinales, dolor abdominal, edema generalizado y anemia sintomática. Los hallazgos de laboratorio pertinentes incluyeron anemia ferropénica (Hb 6.7 g/dl, ferritina 5 ng/ml) e hipoal buminemia marcada (albúmina 2.5 g/dl). Las muestras de biopsia endoscópica de pliegues gástricos gigantes observados a lo largo de la curvatura mayor gástrica revelaron hiperplasia foveolar y pérdida significativa de células parietales. La ecografía endoscópica mostró engrosamiento parietal gástrico con arquitectura conservada y capas de pared gástrica normales. Se diagnosticó enfermedad de Menetrier y se trató al paciente con cetuximab, un anticuerpo monoclonal que inhibe la unión del ligando del factor de crecimiento transformante alfa (TGFa), evitando la proliferación de células de la mucosa gástrica. Después de doce meses de tratamiento, el paciente refirió mejoría de los síntomas y los niveles de la proteína marcadora de proliferación Ki-67 en biopsia gástrica habían disminuido.

ABSTRACT

The diagnosis of a hiatus hernia (HH) is typically confirmed with an upper gastrointestinal barium X-ray, gastroscopy or upper-intestinal endoscopy. In several cases, HH has been diagnosed with an echocardiogram. We here describe a case of an HH visible on an echocardiogram in a male patient with chest pain.

ABSTRACT

Dermatomyositis (DM) is a kind of idiopathic inflammatory myopathy characterized by chronic proximal skeletal muscle weakness and unique skin lesions. However, DM with exfoliation of esophageal mucosa is rare. A 36-year-old male patient complained of muscular soreness of extremities, dysphagia, and pharyngalgia was diagnosed with DM with exfoliation of esophageal mucosa. After treatment with glucocorticoid, immunosuppressant, acupuncture, and endoscopic submucosal dissection (ESD), the above symptoms were disappeared. During the 3-year follow-up period, the results of routine physical examination, laboratory examination, gastroscopy, and imaging examination were normal. High-dose of corticosteroid is needed in the initial treatment, but it must be reduced regularly to avoid adverse reactions. Acupuncture and ESD are also effective as adjuvant therapy.

ABSTRACT

ABSTRACT BACKGROUND: The role of Helicobacter pylori infection on eosinophilic infiltration in duodenal mucosa is poorly studied. An increase in the number of eosinophils in duodenum has been associated with functional dyspepsia. OBJECTIVE: To evaluate the influence of H. pylori infection on duodenal eosinophil count and the role of eosinophilic infiltrate of duodenum in functional dyspepsia. METHODS: Positive and negative H. pylori individuals were included. Both functional dyspeptic patients according to Rome III criteria (cases) and individuals without gastrointestinal symptoms (controls) were enrolled. They were submitted to upper endoscopy and H. pylori infection was verified by gastric histopathology and urease test. Eosinophils in the duodenal mucosa were counted in five high-power fields, randomly selected on slides of endoscopic biopsies. RESULTS: Thirty-nine H. pylori positive (mean age 40.5 and 69.2% women) and 24 negative patients (mean age 37.3 and 75% women) were included. The influence of the infection was observed in the duodenal eosinophil count, which was higher in infected individuals: median 13.2 vs 8.1 in non-infected individuals (P=0.005). When we analyzed patients according to symptoms, cases - mean age 39.6; 71.4% women - and controls - mean age 38.7; 71.4% women - had similar duodenal eosinophil count: median 11.9 and 12.6 respectively (P=0.19). CONCLUSIONS: We did not demonstrate association of duodenal eosinophil count with functional dyspepsia but found association with H. pylori infection.


RESUMO CONTEXTO: O papel de infecção por Helicobacter pylori no infiltrado eosinofílico duodenal ainda é pouco compreendido. Um aumento no número de eosinófilos duodenais tem sido associado a dispepsia funcional. OBJETIVO: Avaliar a influência do H. pylori na contagem de eosinófilos duodenais e o papel do infiltrado eosinofílico duodenal na dispepsia funcional. MÉTODOS: Indivíduos H. pylori positivo e negativo foram incluídos. Ambos os grupos, compreendendo dispépticos funcionais pelos critérios de Roma III (casos) e indivíduos sem sintomas gastrointestinais (controles), foram submetidos à endoscopia digestiva alta para pesquisa de H. pylori, efetuada por histopatologia e teste de urease. Eosinófilos na mucosa duodenal foram contabilizados em cinco campos de maior aumento, selecionados randomicamente nas lâminas de biópsia endoscópicas. RESULTADOS: Trinta e nove indivíduos H. pylori positivo (média de idade 40,5 e 69,2% mulheres) e 24 H. pylori negativos (média de idade 37,3 e 75% mulheres) foram incluídos. A influência da infecção por H. pylori foi observada na contagem de eosinófilos, que foi maior nos positivos: mediana 13,2 vs 8,1 (P=0,005). Quando analisados pacientes de acordo com sintomas, os casos (média de idade 39,6 e 71,4% mulheres) e controles (média de idade 38,7 e 71,4% mulheres), apresentaram semelhante contagem de eosinófilos duodenais: mediana 11,9 e 12,6, respectivamente (P=0,19). CONCLUSÃO: Não demonstramos associação da contagem de eosinófilos duodenais com dispepsia duodenal, mas encontramos associação com infecção por H. pylori.

ABSTRACT

ABSTRACT Objective: To define physician´s behavior in the face of a mentally capable elderly dysphagic patients at risk of pulmonary aspiration, who do not accept oral restriction. Methods: Observational, cross-sectional study, presenting a clinical case of an independent elderly with clinical complaints of dysphagia and laryngotracheal aspiration by flexible endoscopic evaluation of swallowing who rejected the proposal to restrict oral diet. A questionnaire about the patient's decision-making process was used to assess whether the physician was sympathetic and justify their answer, and if they are aware of hierarchy of ethical principles (recognition of the person´s value, autonomy, beneficence, nonmaleficence and justice), in the decision-making process, and which was the main principle that guided their decision. Results: One hundred participants were classified by time since graduation as Group I (less than 10 years) and Group II (more than 10 years). Of them, 60% agreed with the patient's decision, with no difference between the groups. The main reason was autonomy of patients, in both groups. Among those who were not sympathetic, the main argument was beneficence and nonmaleficence, considering the risk between benefit and harm. As to awareness about the hierarchy of principles, we did not find differences between the groups. Autonomy was the principle that guided those who were sympathetic with the patient's decision, and justice among those who didnot agree. Conclusion: Physicians were sympathetic with the patient's decision regarding autonomy, despite the balance between risks of beneficence and nonmaleficence, including death. We propose to formalize a non-compliance term.


RESUMO Objetivo: Definir o comportamento médico diante de paciente idoso disfágico com risco de aspiração laringotraqueal e mentalmente capaz que não aceita a restrição da via oral. Métodos: Estudo observacional, transversal. Apresentamos um caso clínico de idoso, que vive independente, com queixas clínicas e videoendoscopia da deglutição comprovando disfagia e aspiração, que recusou a proposta de restrição da via oral. Um questionário foi aplicado sobre o processo de decisão do paciente, procurando avaliar se o médico torna-se solidário, e que justifique sua resposta, e se tem ciência da hierarquia dos princípios éticos (reconhecimento do valor da pessoa, autonomia, beneficência, não maleficência e justiça), no processo de decisão e qual o principal princípio que norteia sua decisão. Resultados: Cem participantes foram classificados por tempo de formados em Grupo I (até 10 anos) e Grupo II (mais de 10 anos). Deles 60% tornaram-se solidários à decisão do paciente, sem diferença entre os grupos. O principal argumento foi a autonomia do paciente nos dois grupos. Entre os não solidários, foi o binômio beneficência e não maleficência, e o balanço do risco/benefício e malefício. Considerando a ciência sobre a hierarquia dos princípios que regem a decisão, não encontramos diferença entre eles. A autonomia foi o principal princípio na decisão entre os solidários e a justiça entre os não solidários. Conclusão: O médico foi solidário à decisão do paciente em respeito à sua autonomia, apesar dos riscos ponderados da beneficência e da maleficência, inclusive de morte. Propomos o termo de recusa de conduta formalizada.

ABSTRACT

Currently, sedation anesthesia is increasingly used in many medical fields, from gastroscopy to medical imaging. The demand for sedation anesthesia is expected to increase gradually with increasing number of day surgeries and increased expectations from medical services. The demand for sedation anesthesia is considerably higher than the available pool of anesthesiologists; therefore, in a significant number of cases, sedation anesthesia is induced by non-anesthesiologists. However, there is no systematic provision of education or expertise for non-anesthesiologists in delivering sedation anesthesia. In cases of non-anesthesiologists inducing anesthesia, social controversy is often caused by medical accidents and substance abuse. In this review, I have briefly summarized what non-anesthesiologists should know about sedation anesthesia and have presented guidelines simplifying sedation anesthesia for non-anesthesia medical personnel.

ABSTRACT

ABSTRACT BACKGROUND: Helicobacter pylori infection is the most important risk factor for gastric atrophy and intestinal metaplasia, both considered gastric cancer precursor lesions. Therefore, the investigation of the occurrence of H. pylori infection, precursor lesions and associated factors guides the adoption of specific strategies for the control this type of cancer. OBJECTIVE: To evaluate the prevalence of H. pylori infection in patients undergoing upper digestive endoscopy, as well as the prevalence of intestinal metaplasia, atrophy and chronic inflammation and their association with H. pylori infection. METHODS: A retrospective study was performed based on reports of gastric endoscopic biopsies performed in a private laboratory affiliated to the Brazilian Public Health System (SUS). Patients were evaluated for age, gender and type of health service. The samples were evaluated for the presence of H. pylori, and also of chronic inflammation, intestinal metaplasia and glandular atrophy. RESULTS: Of a total of 4,604 patients (mean age 51±16.6), 63.9% were female and 63.1% coming from private health care service. The prevalence of H. pylori infection was 31.7% (n=1,459), and the percentage of infection was significantly higher in patients from public health service (42.0%) in relation to patients from private health service (25.6%). Among H. pylori (+) patients, a higher percentage of intestinal metaplasia (17.7% vs 13.3%) and glandular atrophy (17.6% vs 6.9%) were observed when compared to those H. pylori (-) (P<0.01). From the patients H. pylori (+) with at least one type of precursor lesion (n=418), 161 (38.5%) had metaplasia and chronic inflammation, 160 (38.3%) had atrophy and chronic inflammation and finally 97 (23.2%) presented metaplasia, atrophy and chronic inflammation simultaneously. CONCLUSION: The present study reinforces the association of H. pylori infection with gastric cancer precursor lesions in a Brazilian population, emphasizing the importance of infection prevention measures, as well as the treatment of infected patients, especially in regions with lower socioeconomic levels that show a higher prevalence of infection by H. pylori.


RESUMO CONTEXTO: A infecção por Helicobacter pylori é o fator de risco mais importante para atrofia gástrica e metaplasia intestinal, ambas consideradas lesões precursoras do câncer gástrico. Portanto, a investigação da ocorrência de infecção por H. pylori, das lesões precursoras e dos fatores associados orienta a adoção de estratégias específicas para o controle deste tipo de câncer. OBJETIVO: Avaliar a prevalência de infecção por H. pylori em pacientes submetidos à endoscopia digestiva alta, bem como a prevalência de metaplasia intestinal, atrofia e inflamação crônica e a associação destas com a infecção por H. pylori. MÉTODOS: Foi realizado um estudo retrospectivo com base em laudos de biópsias endoscópicas gástricas realizadas em laboratório privado afiliado ao Sistema Único de Saúde (SUS). Os pacientes foram avaliados quanto à idade, sexo e tipo de serviço de saúde. As amostras foram avaliadas quanto à presença de H. pylori e também de inflamação crônica, metaplasia intestinal e atrofia glandular. RESULTADOS: Do total de 4.604 pacientes (idade média de 51±16,6), 63,9% eram do sexo feminino e 63,1% provenientes de serviços de saúde privado. A prevalência de infecção por H. pylori foi de 31,7% (n=1.459) e o percentual de infecção foi significativamente maior nos pacientes do serviço público de saúde (42,0%) em relação aos pacientes do serviço privado de saúde (25,6%). Entre os pacientes com H. pylori (+), foi observado maior percentual de metaplasia intestinal (17,7% vs 13,3%) e atrofia glandular (17,6% vs 6,9%) quando comparados aos H. pylori (-) (P<0,01). Dos pacientes H. pylori (+) com pelo menos um tipo de lesão precursora (n=418), 161 (38,5%) apresentaram metaplasia e inflamação crônica, 160 (38,3%) apresentaram atrofia e inflamação crônica e, finalmente, 97 (23,2%) apresentaram metaplasia, atrofia e inflamação crônica simultaneamente. CONCLUSÃO: O presente estudo reforça a associação da infecção por H. pylori com lesões precursoras de câncer gástrico em uma população brasileira, enfatizando a importância de medidas de prevenção de infecção, bem como o tratamento de pacientes infectados, principalmente em regiões com níveis socioeconômicos mais baixos que apresentam maior prevalência de infecção por H. pylori.

ABSTRACT

Abstract Purpose: To evaluate serum levels of high-sensitivity C-reactive protein (hs-CRP) in chronic gastritis patients to predict Helicobacter pylori (HP) infection, inflammatory activity, and precancerous lesions. Methods: A total of 811 patients with upper gastrointestinal symptoms and histopathological diagnosis of chronic gastritis were enrolled in the study. On endoscopy, five gastric biopsies were taken according to Modified Sydney protocol, which were stained with hematoxylin & eosin and Giemsa Results: HP infection was found in 28.6% of patients, being significantly more common in specimens with acute and chronic inflammatory activity. Mucosal atrophy, intestinal metaplasia, and dysplasia were found in 20.2%, 18.8% and 2.7% of biopsy specimens. Mean hs-CRP was 1.9±1.6 mg/dl for males and 2.2±1.9 mg/dl for females. hs-CRP average were significantly higher in patients with severe acute inflammation (p:0.049), in patients with severe chronic inflammation (p:0.015) and in those with HP (p: 0.001) . The severity of HP infection increased significantly with the increased degree of acute inflammation, chronic inflammation and hs-CRP level (p=0.001 for both). Conclusion: Serum hs-CRP level increases in patients with chronic gastritis, it could be an indicator of severity of acute or chronic mucosal inflammation, and presence of HP infection. Therefore, hs-CRP may aid the diagnosis of chronic gastritis, but it is not associated with pre-cancerous lesions.

ABSTRACT

IgG4 related disease is a systemic autoimmune disease, which can affect different organs. The most common digestive manifestation is autoimmune pancreatitis (AIP), followed by involvement of bile ducts and the major papilla. The stomach is only rarely involved. We report a 71-year-old diabetic woman consulting for jaundice and weight loss. Abdominal CAT scan, cholangio resonance imaging, endosonography and a serum IgG4 of five times the normal value, lead to the diagnosis of an autoimmune pancreatitis. An upper gastrointestinal endoscopy showed a diffuse thickening of gastric folds. The pathological study confirmed the presence of IgG4 positive plasma cells. The patient was successfully treated with steroids.

ABSTRACT

A dental bridge impacted in the esophagus of a 43-year-old man was successfully removed using endoscopy, without any further complications. It is of utmost importance that the medical staff carefully assess the patient's dental condition, provide clear documentation, and notify the patient appropriately to prevent dental prosthesis-related complications and claims. Anesthesiologists also need to be more cautious in the perioperative period, even after extubation, because this complication may not be completely avoidable.

ABSTRACT

PURPOSE: Quality indicators of the National Endoscopy Quality Improvement Program (NEQIP) and outcome measures of endoscopy in the National Cancer Screening Program (NCSP) in Korea are not clear. We evaluated the quality indicators of the revised NEQIP and outcome measures of endoscopy at different types of healthcare facilities participating in the NCSP. MATERIALS AND METHODS: This study was conducted between March and August 2018 in primary, secondary, and tertiary healthcare facilities that perform endoscopy as a part of the NCSP. Representative endoscopists completed a questionnaire for quality indicators of the NEQIP and provided data on outcome measures for endoscopy. RESULTS: Quality indicators of the NEQIP were mostly acceptable. However, the quality indicators for annual volume of esophagogastroduodenoscopy (EGD) and colonoscopy, training for endoscopy quality improvement by endoscopy nursing staff, colonoscopy reports, documentation of pathologic lesions, quality of endoscopy reprocessing areas, and completion of endoscopy reprocessing education programs were suboptimal. For outcome measures of EGD, the number of photo-documentations and total procedure time were higher at tertiary healthcare facilities than at other facilities (p<0.001 and p=0.023, respectively). For the outcome measures of colonoscopy, colonoscopy completion rate and waiting times for colonoscopy were significantly higher at tertiary healthcare facilities than at other facilities (both p<0.001). CONCLUSION: Outcome measures of endoscopy should be included as quality indicators of NCSP. However, universal outcome measures for all types of healthcare facilities should be established because performance levels of some outcome measures differ among individual healthcare facility types.

ABSTRACT

BACKGROUND/AIMS: Appropriate interval for performing follow-up endoscopy among dyspeptic patients without abnormal findings on previous endoscopy is unclear. We analyzed the multicenter-collected data from the Korean Society of Neurogastroenterology and Motility. METHODS: We collected clinical data of the patients who visited the gastroenterology department and underwent 2 or more sessions of upper endoscopy during 2012–2017 at 6 university hospitals in Korea. Patients with endoscopic interval between 90 days and 760 days were included. For those with multiple endoscopic sessions, only the first 2 were analyzed. Positive outcome was defined as adenoma or cancer in the upper gastrointestinal tract. To identify the point of change and estimate the properties of the stochastic process before and after the change, we used Bayesian regression with Metropolis-Hastings algorithm. RESULTS: There were 1595 patients. Mean age was 58.8 years (standard deviation, 12.8). Median interval of endoscopy was 437 days (standard deviation, 153). On follow-up endoscopy, there were 12 patients (0.75%) who had neoplasia (4 with gastric cancer and 8 with gastric adnoma). As with the prior hypothesis, we presumed the change point (CP) of increase in frequency of organic lesion as 360 days. After random-walk Metropolis-Hastings sampling with Markov-Chain Monte Carlo iterations of 5000, the CP was 560 days (95% credible interval, 139–724). Estimated average of frequency of dysplastic lesions increased by a factor of 4.4 after the estimated CP. CONCLUSION: To rule out dysplastic lesions among dyspeptic patients who had previously normal endoscopy, a 2-year interval could be offered as follow-up interval for repeat upper endoscopy.

ABSTRACT

Gastric schwannoma, a rare mesenchymal tumor originating from the schwann cells of peripheral nerves, rarely occurs in the gastrointestinal tract. It accounts for only 0.2% of all gastric tumors and 2~6% of gastric mesenchymal tumors. Gastric schwannoma is observed as a subepithelial tumor on endoscopy; it is covered with normal mucosa, rendering its preoperative differential diagnosis difficult. An asymptomatic 43-year-old woman visited our hospital after a 7-cm ulcerofungating mass was detected in the lesser curvature of the gastric body on gastroscopy. Abdominal CT revealed multiple enlarged lymph nodes, and ¹⁸F-fluorodeoxyglucose (FDG) PET demonstrated a subtle uptake of FDG, suggestive of advanced gastric cancer. After three failed attempts of endoscopic biopsy, the patient underwent total gastrectomy with lymphadenectomy and was subsequently diagnosed with gastric schwannoma. Herein, we report this case with a literature review.

ABSTRACT

Gastric neuroendocrine tumors are rarely seen in the gastric tumors, because there are few case reports and the clinical diagnosis rate is low. There is no consensus treatment method in the world. However, with the benefit of esophagogastrodenoscopy and widespread use of proton pump inhibitors, the diagnostic rate of gastric neuroendocrine tumors is on the increase, which gives us an updated understanding for the pathogenesis and pathophysiology of the disease. By studying its pathogenesis, scholars have found that hypergastrinemia caused by various causes is closely related to its occurrence. Gastric neuroendocrine tumors are classified into different types or pathological grades depending on the state of progression of the disease and the unique clinical manifestations. Clinically used diagnostic methods include gastroscopy, medical imageology, nuclear medicine, gastrin, CgA, etc. There are also differences in treatments depending on the clinical classification. If the disease progresses rapidly and the grade is high, surgical resection of the lesion plus postoperative adjuvant chemotherapy should be actively performed. Other better treatments are still being explored.

ABSTRACT

BACKGROUND/AIMS: Fundic gland polyps (FGPs), hyperplastic polyps (HPs), and xanthomas (XTs) are common benign gastric lesions that can be diagnosed by endoscopic appearance alone in most cases. The aim of this study was to evaluate associations between gastric cancer and these benign lesions. METHODS: Two expert endoscopists reviewed a series of gastroscopy images. FGPs, HPs, and XTs were diagnosed by endoscopic appearance, whereas all gastric cancers were confirmed pathologically. RESULTS: Of the 1,227 patients reviewed, 114 (9.3%) had a concurrent or past history of gastric cancer. The overall prevalences of FGPs, HPs and XTs were 9.4%, 6.3% and 14.2%, respectively. HPs and XTs coexisted in 1.6% of patients, whereas other combinations were rarer. XTs were observed in 39.3% and 11.5% of patients with and without gastric cancer, respectively (p<0.001). In contrast, no gastric cancer patients had FGPs, whereas 10.4% of patients without cancer had FGPs (p<0.001). The prevalence of HPs was similar between the two groups (8.8% and 6.0% of patients with and without cancer, respectively, p=0.29). Multivariate and Mantel-Haenszel analyses demonstrated that XTs were positively associated and FGPs were negatively associated with gastric cancer. CONCLUSIONS: XTs and FGPs might be useful as endoscopic risk indicators for monitoring gastric cancer.
