RESUMO
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
