RESUMO

In Peru, new cases of asymptomatic HCV infection are reported with certain frequency in patients with or without antecedents of blood transfusion. Although serologic screening has improved notoriously in the last years, there is still a population of polytransfused patients with high HCV risk (e.g. hemodialyzed patients), making up a major reservoir. Based on this premise, we decided to study the risk of the health worker population in Peru as another major HCV risk group. A total of 2,769 health workers from 7 Public Hospitals and 2 Private Hospitals in the City of Lima and from 7 Public Hospitals in 4 major/main cities of Peru (Chiclayo, Trujillo, Arequipa, and Cusco) were studied. All those workers, who due to their area of work had higher contact with blood and/or blood derivatives (Surgery, ICU, Traumatology, Gynecology, Gastroenterology, Hemodialysis and Laboratories-Blood Banks) were studied. The studied population accounts for 30% of the total health worker population in these services. All serums underwent the EIA-3 test (HCV-Cobas-Core, Lab. Roche, USA). The positive results were confirmed by RT-HCV (Ampiclor, Roche). The positive serums were confirmed by PCR and the positive results with high viral load underwent HCV genotyping (AMPICLOR-Roche Diagnostic, IGEN Diagnostic USA). Of the 2,769 health workers studied in Peru, 32 were positive for HCV antibodies (1.16% of the total number). Lima showed a prevalence slightly higher than the provinces: 26 out of 2,112 vs. 6 out of 657, or 1.23% vs. 0.91%, respectively. The higher risk is assumed by professional with higher level of contact with blood: 2 physicians (Hemodialysis), 5 nurses (HD) and Lab-Blood Bank technicians. The physicians and nurses share the same risk. If we segregate Lima from provinces, it can be seen that the highest risk is in Lima (1.34% compared to 1.07% in provinces). There is a major risk in health workers and the figures are slightly above those that were suspected for Peru (between 0.4 and 1.0). Finally, we can conclude that the group with the highest HCV risk among health workers is the group specialized in hemodialysis, followed by laboratory (1.79%), surgery (1.40%), and gastroenterology (0.8%). This is the first report at national level of HCV sero-prevalence in Peru.

RESUMO

Se revisaron 2,913 informes de endoscopías, realizadas en 2,394 pacientes del Hospital General Cayetano Heredia entre 1975 y 1985. 942 casos tuvieron exámenes radiológicos previos. Existió la tendencia durante los últimos años, a solicitar exámenes endoscópicos como método diagnóstico inicial y único. Las lesiones de mayor incidencia fueron: las gástricas, siguiéndole en orden de frecuencia las duodenales y finalmente las esofágicas. En el 30% de casos no se visualizaron anormalidades durante el examen endoscópico. Los diagnósticos Endoscópico y Radiológico coincidieron en un 35.8% de casos. La correlación entre los diagnósticos Endoscópico y Patológico (43%), fue mayor que el hallado para los Radiológicos y Patológicos (30%). A excepción de las lesiones elevadas de origen gástrico, la endoscopía demostró mayor eficiencia, estadísticamente significativa (p <0.05), que la radiología utilizando la técnica de doble contraste. Se discuten los resultados obtenidos, correlacionándolos con la literatura revisada

RESUMO

Se llevó a cabo un estudio retrospectivo y multicéntrico de los exámenes endoscópicos realizados en los servicios de gastroenterología de seis centros hospitalarios de Lima y Callao, durante el período comprendido entre los años de 1981 a 1985. Se seleccionaron los casos de cáncer gástrico diagnosticados endoscópicamente y con comprobación histopatológica. De las 27,424 endoscopías realizadas, se hallaron 946 casos de cáncer gástrico que representa el 3.45% de esos exámenes. El cáncer avanzado representó el 91.3% (864 casos), el tipo intermedio el 1.8% (17 casos) , y el incipiente el 6.9% (65 casos). La incidencia por sexos fue de 466 casos (49.3%) para el masculino, y 480 casos (49.7%) el femenino. En relación a las edades, el 79.4% de casos correspondió a pacientes mayores de 50 años. La incidencia del cáncer gástrico en nuestro país es significativa, se hacen comparaciones con las de otros estudios similares, nacionales y extranjeros. Considerándose que la endoscopía gastrointestinal constituye un examen electivo para la detección de esta enfermedad, se discute su efectividad frente a otros métodos de diagnóstico
