ABSTRACT

Introducción: La bactibilia es la presencia de bacterias en bilis vesicular y está relacionada con la aparición de complicaciones sépticas y con el desarrollo de infección en herida quirúrgica de la colecistectomía. En este estudio investigamos si la bactibilia se correlaciona con infección de herida posterior a colecistectomía abierta. Material y métodos: Estudio observacional, descriptivo, de pacientes sometidos, entre enero y diciembre de 2006, a colecistectomía abierta en forma electiva por colecistitis crónica litiásica, a quienes se les realizó cultivo de bilis en el transoperatorio. Se identificaron dos grupos: con cultivo biliar negativo (grupo 1) y con cultivo biliar positivo (grupo 2). Las variables estudiadas fueron edad, sexo, resultados del cultivo, absceso, celulitis, seroma y hematoma. El análisis estadístico incluyó c2 de Pearson o prueba exacta de Fisher y t de Student. Resultados: Se estudiaron 80 pacientes (n = 40 por grupo), 24 hombres (30%) y 56 mujeres (70%), en quienes se practicó colecistectomía abierta y que contaban con cultivo biliar para el análisis. La morbilidad general fue de 42.5%. La tasa de infección del sitio quirúrgico fue de 11.25%. En el grupo 1, dos pacientes presentaron abscesos y dos celulitis; en el grupo 2, cuatro abscesos y uno celulitis. No hubo diferencia significativa al comparar la infección del sitio quirúrgico entre ambos grupos. Conclusiones: La presencia de bacterias en los cultivos de bilis vesicular no se correlacionó con el desarrollo de infección en herida quirúrgica posterior a colecistectomía.


BACKGROUND: Bactibilia is the presence of bacteria in gall bladder bile and may play a role in the appearance of septic complications. It has been related to increased rates of surgical site infection after cholecystectomy. In this study we investigated whether bactibilia correlates with the presence of surgical site infection after cholecystectomy. METHODS: In this observational and descriptive study we investigated those patients operated by open cholecystectomy because of chronic cholecystitis. Patients had bile culture during surgery (January-December 2006). There were two study groups: patients with negative biliary culture (group 1) and patients with positive biliary culture (group 2). Variables were age, gender, biliary culture reports, abscess, cellulitis, seroma, and hematoma. Statistical analysis included Pearson chi(2) or Fisher's exact test. For independent variables, Student t-test was used. RESULTS: Eighty patients were included (n = 40 per group). There were 24 males (30%) and 56 females (70%) who had open cholecystectomy and had biliary culture. General morbidity was 42.50% and surgical site infection rate in general was 11.25%. There were two patients with abscesses and two patients with cellulitis in group 1. There were four patients with abscesses and one patient with cellulitis in group 2. There was no statistically significant difference when comparing surgical site infection in both groups. CONCLUSIONS: The presence of bacteria in gall bladder cultures does not correlate with the development of surgical site infection after open cholecystectomy.
