Linitis plástica como presentación de un carcinoma lobulillar de mama / Linitis plastica as a presentation of lobular breast carcinoma

El estómago es un lugar infrecuente de metastatización del cáncer de mama. Presentamos un caso de linitis plástica metastásica de un carcinoma lobulillar de mama localmente avanzado. La distinción entre el origen primario gástrico del secundario es fundamental, y se basa en estudios inmunohistoquímicos de las biopsias (AU)

The stomach is an infrequent site of breast cancer metastasis. We report a case of metastatic linitis plastica from locally advanced lobular breast carcinoma. The distinction between primary and secondary gastric origin is essential and is based on immunohistochemical studies of biopsies (AU)

Pancreatitis biliar. Cinética de pruebas funcionales hepáticas y canal común biliopancreático - reflujo biliopancreático / Biliary pancreatitis. Liver function tests and common biliopancreatic channel kinetics - biliopancreatic reflux

OBJETIVO: Estudio de la prevalencia de reflujo biliopancreático (RBP)/canal común biliopancreático (CCBP) en pacientes con pancreatitis biliar (PB) sometidos a colecistetomía (CST) y colangiografía intraoperatoria (CIO) y análisis de la cinética de pruebas funcionales hepáticas (PFH) en comparación con un grupo control (GC) de colelitiasis sintomática. MATERIAL Y MÉTODOS: Estudio retrospectivo de 107 pacientes consecutivos con PB. Se determinó la existencia de RBP-CCBP en la CIO y se analizaron las PFH al ingreso (AI), a las 48 horas y en el examen preoperatorio (AP). La variación analítica se analizó entre grupos según existencia de RBP-CCBP y entre el AI y AP, según intervalo ingreso-intervención (III) y dentro del mismo grupo mediante determinación de la ratio valor observado-valor máximo normal (VO/VMN). RESULTADOS: La incidencia de CCBP fue de 38,3% en PB vs 5,0 en GC (p = 0,0001) y fue independiente del III a diferencia de la odditis apuntando a una alteración anatómica para la primera y funcional para la segunda. Las variaciones analíticas no muestran diferencias entre grupos en función de la existencia de CCBP, pero con ausencia de diferencias al analizar la ratio VO/VMN en FA y GGT, lo que indica un mayor grado de colestasis en los pacientes con RBP-CCBP. La incidencia de dilatación de vía biliar US fue del 10,3% asociándose a CCBP. CONCLUSIONES: El RBP-CCBP en PB genera un mayor grado de colestasis e incertidumbre en la estimación de coledocolitiasis asociada y excesiva sobreindicación de ERCP-EE. Los marcadores US y bioquímicos de coledocolitiasis tienen una baja especificidad en PB por la existencia de CCBP lo que obliga a incluir a la colangiografía por RMN como exploración previa a la ERCP-EE

OBJECTIVE: To determine the prevalence of biliopancreatic reflux (BPR) in patients with biliary pancreatitis (BP) undergoing elective cholecystectomy with intraoperative cholangiography (IOC) in comparison with a control group of symptomatic cholelithiasis (CG). PATIENTS AND METHODS: Retrospective review of 107 consecutive BP cases. BPR was determined by IOC and liver function tests (LFT) were recorded at admission (A), 48hours, and preoperative examination (P). LFT analysis between A and P were analysed between groups with respect to BPR, time interval to cholecystectomy within the same group and by determination of observed value/maximum normal value ratio (OV/MNV). RESULTS: BPR incidence was 38.3% in BP in comparison with 5% in CG (p = 0.0001) it was independent from interval time to cholecystectomy, in contrast with Odditis, suggesting an anatomical condition for CCBP and a functional one for Odditis. LFT analysis showed no differences in relation to BPR incidence. LFT excluding AP and GGT returned to normal values with significant differences in OV/MNV when BPR was present which points to an increased cholestasis in BPR group. US dilatation of CBD was noted in 10.3% and was associated to CCBP. CONCLUSIONS: BPR in BP increases cholestasis and contributes to confusion in the estimation of common bile duct stones increasing ERCP-EE rates. US and biochemical markers of CBDS show a low specificity due to BPR-CCBP which suggests that MRI-cholangiography is a mandatory exploration before ERCP-EE examination
