Endoscopic ultrasound-guided fine-needle aspiration for splenomegaly and focal splenic lesion: is it safe, effective and necessary?

INTRODUCTION: splenomegaly and/or focal splenic lesions (FSL) have limited histopathologic studies due to the risk posed by splenic punctures. Percutaneous biopsies with a fine needle are difficult, especially due to interposition of gases, ascites, obesity or a history of abdominal surgery. On the other hand, endoscopic ultrasound (EUS) takes advantage of the proximity of the gastric wall to the spleen in order to puncture and visualize the needle and its movements in real time. OBJECTIVE: to describe the initial experience and results obtained with EUS-FNA in patients with splenomegaly or FSL. MATERIALS AND METHODS: this was a descriptive observational study. EUS-FNA of the spleen was performed with a slow-pull technique, which avoided fanning with an average of 3 needle passes. Biopsies were sent in Cytorich RedTM solution for analysis by cytology and cell block. RESULTS: punctures were performed in 15 patients (9 females) and the median age was 67 years (range 44-86). Patients studied due to an enlarged spleen or splenic FSL, in the context of fever of an unknown origin, adenopathies and abnormal weight loss were included. A conclusive diagnosis was achieved by EUS-FNA in 10 patients (66.7 %), 4 were large cell type B non-Hodgkin's lymphoma and one Hodgkin's lymphoma. There were no immediate or delayed complications related to the procedure. CONCLUSIONS: EUS-guided splenic punctures appear to be safe, effective and may be necessary in some clinical settings in order to complete the etiologic filiation of splenomegaly of an uncertain origin or FSL and to rule out malignancy.

Cat scratch esophagus.

The cat scratch esophagus is an uncommon entity. The first case described in the literature of this type of lesions was published in 2007 and was located in the colon. There are two cases described in the esophagus, this has been the first detected by endoscopic capsule. It is defined by the presence of linear, erythematous, shiny and superficial breaks of the mucosa without significant hemorrhage associated. The diagnosis is morphological. Even though the etiology is unknown, it has been postulated that the main pathogenic mechanism is barotrauma secondary to insufflation. It has also been described association with other processes that can affect the esophageal elasticity as well as the previous use of NSAIDs.

Histopathological differences in patients with biopsy-proven non-alcoholic fatty liver disease with and without type 2 diabetes / Diferencias histopatológicas en pacientes con diabetes mellitus tipo 2 y no diabéticos con enfermedad hepática grasa no alcohólica diagnosticada con biopsia

Background and aims: Prevalence of non-alcoholic fatty liver disease (NAFLD) in developed countries is 30% in the general population and 50% in patients with type 2 diabetes mellitus (T2DM). The aim of this study was to compare the severity of NAFLD, as assessed by liver biopsy and using the non-invasive index NAFLD Fibrosis Score (NFS), in subjects with and without T2DM. Patients and methods: The study sample consisted of 217 patients with biopsy-proven NAFLD. Anthropometric assessments, laboratory tests, histological criteria established by the Non-alcoholic Steatohepatitis Clinical Research Network (NASH CRN), and the NFS were recorded. Results: Patients with T2DM (n=36; 16.5%) had higher HOMA-IR values (6.3±3.6 vs. 3.3±2.4; p<0.0001), GGT levels (125.2±102.3 vs. 82.5±70.6IU/l; p<005), and NFS index (−0.6±0.2 vs. −1.8±0.1; p<0.001) than subjects with no T2DM. Patients with T2DM were found higher rates of NASH (72.2% vs. 48.6%; p<0.05), advanced steatosis (80.6% vs. 63%; p<0.05), and liver fibrosis (75% vs. 43.1%, p<0.05) than patients with no T2DM. Patients with T2DM also had higher NFS values (−0.6±1.2 vs. −1.8±1.8: p=0.01). A logistic regression analysis adjusting for age, gender and BMI showed a significant independent association between NASH and presence of T2DM (OR=4.2: 95% CI: 1.4-12.1; p=0.007). A second model adjusting for the same covariates showed T2DM to be an independent factor associated to advanced fibrosis (OR=4.1; 95% CI: 1.7-9.7). Conclusion: Patients with T2DM have more advanced degrees of NAFLD and advanced fibrosis as assessed by liver biopsy and the NFS index. Particular attention should be paid to the study and monitoring of NASH in patients with T2DM

Antecedentes y objetivos: La prevalencia de la enfermedad hepática grasa no alcohólica (NAFLD) en los países desarrollados es del 30% de la población general y del 50% de los pacientes con diabetes mellitus tipo 2 (DM2). El objetivo de este estudio fue comparar la gravedad de NAFLD evaluado por biopsia hepática y con un índice no invasivo NAFLD Fibrosis Score (NFS) en sujetos con DM2 frente a pacientes no diabéticos. Pacientes y métodos: Este estudio se llevó a cabo entre 217 pacientes con diagnostico mediante biopsia de NAFLD. Se registraron la valoración antropométrica, pruebas de laboratorio, criterios histológicos establecidos por la Red de Investigación Clínica de Esteatohepatitis No Alcohólica (NASH) y NFS. Resultados: Los pacientes con DM2 (n=36; 16,5%) tuvieron más HOMA-IR (6,3±3,6 vs. 3,3±2,4; p<0,0001), GGT (125,2±102,3 vs. 82,5±70,6UI/L); p<0,05) e índice NFS (−0,6±0,2 vs. −1,8±0,1; p<0,001) que los sujetos sin DM2. Los pacientes con DM2 presentaron mayor porcentaje de EHNA (72,2 vs. 48,6%; p<0,05), grado avanzado de esteatosis (80,6 vs. 63%; p<0,05) y fibrosis hepática (75 vs. 43,1%; p<0,05) que los pacientes sin DM2. Los pacientes con DM2 presentaron también valores más altos de NFS (−0,6±1,2 vs. −1,8±1,8; p=0,01). El análisis de regresión logística ajustado por edad, sexo e IMC mostró asociación significativa independiente entre la esteatohepatitis y la presencia de DM2 (OR=4,2; IC 95%: 1,4-12,1; p=0,007). Un segundo modelo ajustado por las mismas covariables mostró que la DM2 fue un factor independiente asociado a la fibrosis avanzada (OR=4,1; IC 95%: 1,7-9,7). Conclusión: Los pacientes con DM2 tienen grados más avanzados de NAFLD y fibrosis avanzada evaluados mediante biopsia hepática y el índice NFS. Debe prestarse especial atención al estudio y seguimiento de la esteatohepatitis en pacientes con DM2
