Effectiveness of systematic alphanumeric coded endoscopy for diagnosis of gastric intraepithelial neoplasia in a low socioeconomic population.

Background and study aims: In the Western world, gastric cancer (GC) usually presents at an advanced stage, carrying a high mortality rate. Studies have reported that 14 % to 26 % of GCs are missed at endoscopy up to 3 years before diagnosis. Systematic Alphanumeric Coded Endoscopy (SACE) has been proposed to improve quality of esophagogastroduodenoscopy (EGD) by facilitating a complete examination of the upper gastrointestinal tract. This prospective cross-sectional study was designed to determine the frequency of gastric intraepithelial neoplasia (GIN) by using the SACE approach in cohort of patients from low socioeconomic level. It also used non-targeted biopsies to evaluate the frequency of premalignant conditions. Patients and methods: A total of 601 consecutive asymptomatic or dyspeptic patients were enrolled between January 2013 and November 2014 at the Huacho regional hospital in Peru. The SACE method proposed by Emura et al, which divides the stomach into 5 regions and 21 areas, was routinely used for diagnosis. Biopsy samples were obtained from any endoscopically detected focal lesion. To evaluate gastric premalignant conditions, 4 non-targeted biopsies were taken. Results: A total of 573 patients were analyzed. The mean age was 57 years, and the female:male ratio was 1.9 : 1. In all cases, complete photo-documentation of the 21 gastric areas was achieved. The overall rate of detection of GIN was 2.8 %. Low-grade displasia, high-grade dysplasia, and adenocarcinoma were found in 13 (2.3 %), 2 (0.3 %), and 1 (0.2 %) of the patients, respectively. The prevalence of at least 1 premalignant condition was 31 %, and helicobacter pylori infection was found in 57 % of patients. Conclusions: Using the SACE approach and with proper training, we have reported herein a high frequency of GIN in patients from a low socioeconomic status. Gastric cancer detection can be improved in a Western endoscopy setting when SACE, as a screening method, is performed by a trained endoscopist.

[Systemic inflammatory response syndrome as prognostic indicator in hospitalized cirrhotic patients]. / Síndrome de respuesta inflamatoria sistémica como indicador pronóstico en pacientes cirróticos hospitalizados.

OBJECTIVE: The systemic inflammation worsens circulatory disorders in cirrhotic patients and recently the systemic inflammatory response syndrome (SIRS) may be a prognostic indicator therein. The aim of the study was to determine whether the presence of SIRS at admission in hospitalized cirrhotic patients is associated with complications or mortality. MATERIALS AND METHODS: A retrospective cohorts study was conducted at the Daniel Alcides Carrion National Hospital.Hospitalized cirrhotic patients admitted from July 2008 to December 2010 without significant comorbidities, malignancy,HIV infection, or stay less than 72 hours were included. Presence of SIRS at admission and the occurrence of complications or death after 72 hours of admission were evaluated. RESULTS: 150 cirrhotic patients were admitted, six were excluded;three for lower survival at 72 hours, one for neoplasia, one for severe heart failure and two for chronic renal failure. One hundred forty four patients were included, 95 (66%) patients had SIRS at admission. There was no significant difference in age, sex, etiology, in both groups. SIRS was associated with higher scores of MELD and Child-Turcotte Pugh. Of the group of patients with SIRS, 41 (43%) had complications and 16 (16.8%) died, while the group without SIRS 5 (10.2%) had complications and two (4%) died p < 0.0001 and p=0.028 respectively. The most common complications were infections and hepatic encephalopathy. In multivariate analysis SIRS was associated with complications (p < 0.006) but not with mortality(p < 0.276). CONCLUSIONS: SIRS is common in hospitalized cirrhotic patients and is associated with in-hospital complications.

Síndrome de respuesta inflamatoria sistémica como indicador pronóstico en pacientes cirróticos hospitalizados / Systemic inflammatory response syndrome as prognostic indicator in hospitalized cirrhotic patients

Objetivo: La inflamación sistémica empeora los trastornos circulatorios en el paciente cirrótico y recientemente el síndrome de respuesta inflamatoria sistémica (SRIS) podría ser un indicador pronóstico en ellos. El objetivo del estudio fue determinar si la presencia de SRIS al ingreso en pacientes cirróticos hospitalizados está asociada a complicaciones o mortalidad. Materiales y métodos: Estudio de cohortes retrospectiva, realizado en el Hospital Nacional Daniel Alcides Carrión. Se admitieron pacientes cirróticos hospitalizados desde julio 2008 hasta diciembre 2010 sin comorbilidades importantes, neoplasia maligna, infección VIH, o estancia fue menor a 72 horas. Se evaluó presencia de SRIS al ingreso y la aparición de complicaciones o muerte después de 72 horas del ingreso. Resultados: Fueron 150 pacientes cirróticos admitidos, se excluyeron 6, tres por supervivencia menor a las 72 horas, uno por neoplasia, uno por insuficiencia cardiaca severa y dos por insuficiencia renal crónica. En total 144 pacientes ingresaron al estudio, 95 (66%) pacientes presentaron SRIS al ingreso. No hubo diferencia significativa en cuanto a edad, sexo, etiología, en ambos grupos. SRIS estuvo asociado a mayores puntajes de MELD y Child-Pugh Turcotte. De los pacientes con SRIS, 41 (43%) se complicaron y 16 (16,8%) fallecieron, mientras que del grupo sin SRIS 5 (10,2%) se complicaron y 2 (4%) fallecieron, (p<0,0001y p=0,028 respectivamente). Las complicaciones más frecuentes fueron las infecciones y encefalopatía hepática. En el análisis multivariado SRIS estuvo asociado a complicaciones (p<0,006) mas no a mortalidad (p<0,276). Conclusiones: SRIS es frecuente en pacientes cirróticos hospitalizados y está asociado a complicaciones intrahospitalarias.
