The performance and normative values obtained for this low-cost water-perfused HRM seems to be adequate for clinical use.

Background: High-resolution manometry is more costly but clinically superior to conventional manometry. Water-perfused systems may decrease costs, but it is unclear if they are as reliable as solid-state systems, and reference values are interchangeable. Aim: To validate normal values for a new water-perfusion high-resolution manometry system. Methods: Normative values for a 24-sensors water perfused high-resolution manometry system were validated by studying 225 individuals who underwent high resolution manometry for clinical complaints. Patients were divided in four groups: group 1 - gastroesophageal reflux disease; group 2 - achalasia; group 3 - systemic diseases with possible esophageal manifestation; and group 4 - dysphagia. Results: In group 1, a hypotonic lower esophageal sphincter was found in 49% of individuals with positive 24 h pH monitoring, and in 28% in pH-negative individuals. In groups 2 and 3, aperistalsis was found in all individuals. In group 4, only one patient (14%) had normal high-resolution manometry. Conclusions: The normal values determined for this low-cost water-perfused HRM system with unique peristaltic pump and helicoidal sensor distribution are discriminatory of most abnormalities of esophageal motility seen in clinical practice.

RESUMOObjetivo: Avaliar o perfil dos pacientes com neoplasia maligna de estômago, que receberam atendimento e tratamento no Hospital Municipal Dr. Jose de Carvalho Florence (HMJCF). Métodos: Estudo retrospectivo a partir do levantamento de prontuários. Análises foram feitas com uma amostragem e proporções esperadas desiguais e Quadros de contingência. Para se verificar associação entre as variáveis, utilizado o teste Qui–Quadrado de Pearson, considerando-se p ≤ 0,05, em um grau de confiabilidade de 95%. Resultados: O sexo masculino é o com maior número de casos na proporção de 2:1. A idade média ao diagnóstico é 65,16 anos. A queixa mais comum apresentada por estes pacientes foi a epigastralgia seguido pela inapetência. A maioria dos tumores encontrava-se no antro gástrico. Cinquenta e nove destes pacientes foram submetidos a cirurgia sendo 45 com intuito curativo. A sobrevida média foi de 15 meses e a taxa de sobrevida em 5 anos de apenas 6%.  Conclusão: O CG é uma doença muito agressiva e de prognóstico ruim. Suas manifestações iniciais são inespecíficas, o que torna seu diagnóstico em fases iniciais muito difícil.Palavras chave: Câncer Gástrico, Úlcera gástrica, Perfil de SaúdeABSTRACTObjective: Evaluate the profile of patients with malignant neoplasia of stomach, receiving care and treatment in Hospital Municipal Dr. Jose de Carvalho Florence (HMJCF). Methods: Retrospective study based on a survey of medical records. Analysis were made with a sampling and unequal expected ratios and contingency tables. To assess the association between variables, will be used the chi-square test, considering p ≤ 0.05, at a reliability level of 95%. Results: The largest number of cases are male, ratio of 2:1. The average age at diagnosis is 65.16 years. Caucasians followed by mulatto were the most frequent with Gastric Cancer. The most common complaint presented by these patients was abdominal pain followed by loss of appetite. Most tumors found in the gastric antrum. Fifty-nine of these patients underwent surgery with curative intent in 45. Twenty of them had some type of metastasis intraoperatively and 12 outpatients progressed to metastatic lesions. The median survival was 15 months and the survivor rate in 5 years was only 6%. Conclusion: The Gastric Cancer is a very aggressive and poor prognosis disease. Its initial symptoms are nonspecific, making diagnosis difficult in the early stages.Keywords: Gastric Cancer, Gastric Ulcer, Health Profile.

The Chicago Classification has been the leading guideline for esophageal motility disorders evaluation and classification since the advent of high-resolution manometry. Esophagogastric junction (EGJ) barrier function was neglected until the most current update of the classification when a technical review on the topic was recently released (1) . In this publication, the Contractility Integral of the Esophagogastric Junction (EJG-CI) was deemed "currently the best validated metric of EGJ contractile vigor and should be adopted".Each manometry system has different reference values depending on its operating mechanism. This is mainly visible in water perfusion systems, where the response of the sensors is slower, given the latency of the response time to the passage of water through the sensors. We have published normative values for a
