Enfermedad pélvica inflamatoria aguda, diagnóstico laparoscópico, etiología bacteriana (es)Downloads
Objetivos: estudiar la frecuencia de la enfermedad pélvica inflamatoria (EPI), evaluar los factores de riesgo, determinar por medio del diagnóstico laparoscópico la eficacia del diagnóstico clínico, describir la etiología bacteriana de esta entidad y documentar sus principales complicaciones. Diseño: estudio observacional analítico de casos y controles. Lugar: Servicio de Infecciosas del Instituto Materno Infantil (lMI) de Santa Fe de Bogotá, Hospital de tercer nivel. Población, criterios de inclusión y exclusión: pacientes que consultaron entre 1992 y 1993 por dolor pélvico y diagnóstico clínico de EPI, sin evidencia de embarazo o infección de otro órgano, sin tratamiento antimicrobiano previo y que firmaron un consentimiento informado. Se consideraron casos las pacientes que mostraron EPI en la laparoscopia y con troles las pacientes que mostraron otra patología. Medición, variables y métodos para evaluarlas: se diligencio una historia clínica de la paciente con énfasis en los facto res de riesgo, los datos del examen clínico y de laboratorio. EI patrón de oro diagnóstico fue la laparoscopia. Se realizo la clasificación clínica y laparoscópica y se tomaron muestras microbiológicas del fondo de saco posterior y endocervicales. Los casos y los controles se compararon en relación con las variables sociodemográficas por medio de la prueba t Student, se realizó análisis univariado de asociación entre los factores de riesgo y la entidad así como entre los criterios diagnósticos y la presencia de la entidad por medio del riesgo relativo indirecto (OR), con los intervalos de confianza. Se determinó la frecuencia de los gérmenes aislados. Resultados: la prevalencia de la entidad fue del 9.2/1000. Se estudiaron 63 pacientes, 45 casos y 18 controles. Un 15% de las pacientes eran menores de 20 años. La sensibilidad global del examen clínico fue del 71 %. La secreción endocervical purulenta (OR=5,65) fue el único criterio con asociación estadísticamente significativa a la EPI. Se confirmó la etiología polimicrobiana de la EPI con la presencia de Neisseria gonorrhoeae y Chlamydia trachomatis así como también de gérmenes aerobios y anaerobios. Conclusiones: la EPI afecta primordialmente mujeres jóvenes en edad reproductiva y existe una relación con las enfermedades de transmisión sexual. EI diagnóstico clínico puede llevar a un importante número de falsos positivos, por lo que se recomienda el uso de la laparoscopia en casos dudosos y cuando se presente masa al tacto vaginal. EI tratamiento debe cubrir todos los gérmenes potencialmente causales de la entidad. Se requiere un estudio colaborativo nacional para determinar con mayor precisión los factores de riesgo.
Objectives: To study the frequency of pelvic inflammatory disease (PID), and to evaluate its risk factors. Additionaly, to determine by laparoscopy the efficacy of the clinical diagnosis and to describe the bacterial etiology of PID and its complications. Design: Case control study. Place: Infectology Service at Instituto Materno Infantil, Santa Fe de Bogota, a third level hospital. Case subjects, inclusion and exclusion criteria: Outpatients with pelvic pain and clinical diagnosis of PID between 1992 and 1993 were included in the study. AUof them accepted and signed an informed consent. The exclusion criteria were pregnancy, another concomitant infectious disease and to have received any antimicrobial treatment in the days previous to consultation. Cases were the patients with PID confinned by laparoscopy and the control group was conformed by patients with another pathology. Methods, variables and statistical procedures: A medical history was done with special attention to the risk factors, and the clinical and laboratory findings. The gold standard was the laparoscopy. The clinical and laparoscopic classification was done and samples were taken for the microbiological studies. Case and controls were compared regarding to socio-demographic variables using the Student's t test. Associated univariate analisys was done between the risks factors and the entity as well as the diagnostic criteria and the occurrence of PID using the indirect relative risk (OR) with the confidence intervals. The frequency of bacterial isolates was also determined. Results: The prevalence of the PID was 9.2/1,000. A total of 63 patients were included in the study, 45 cases and 18 controls, 15% of the patients were less than 20 years old. The sensitivity of the clinical diagnosis was 71 %. The endocervical purulent exudate was the only criteria statistically significant associated with PID (OR=5.65). The polimicrobial etiology of PID was confirmed with the isolation of Neisseria gonorrhoeae, Chlamydia trachomatis and a group of aerobic and anaerobic bacteria. Conclusions: PID was diagnosed in young women, in childbearing age and it was related with sexually transmitted diseases. The diagnosis based only on clinical criteria would give false positives. The laparoscopy procedure is recommended in cases with no clear diagnosis and when a mass is detected at the gynecological examination. The treatment must cover all bacteria implicated with this pathology. A national collaborative study is required in order to determine the risk factors for PID in our population.
