[An analysis of the value of bowel preparation for preventing postoperative complications in endoscopic surgery]. / Análisis de la utilidad de la preparación intestinal en la prevención de complicaciones postoperatorias en cirugía endoscópica.

OBJECTIVES: To assess the relationship between mechanical preparation of the bowel before endourological surgery and the occurrence of postoperative complications. MATERIALS AND METHODS: A prospective, randomized study was conducted in 162 patients undergoing TUR of the bladder, TURP, and lase adenomectomy from October 2008 to February 2009. No patient was excluded. An enema was administered before surgery to 66 patients, but not to the remaining patients. Variables analyzed included occurrence of urinary tract infection (UTI), fever, acute urinary retention (AUR), postoperative need for enemas or laxatives, surgical field contamination, and mean hospital stay. A descriptive analysis, a means comparison (t test), and a Chi-square test were performed. RESULTS: Mean patient age was 70.5 years (SD+/-10.62), and mean hospital stay 4.8 days (SD+/-3.9). UTI occurred in 6.2% of patients, fever in 3.1%, and AUR in 1.2%, and 15.4% of patients required enemas or laxatives. Fecal contamination of the surgical field was found in one patient (0.6%). There were no statistically significant differences between the study groups in the variables analyzed. CONCLUSIONS: In our series, bowel preparation using enema has shown no value for decreasing postoperative complications of endourological surgery.

Objetivos: Determinar la relación entre la preparación mecánica intestinal previa a la cirugía endourológica y la existencia de complicaciones postoperatorias. Material y métodos: Diseñamos un estudio prospectivo y aleatorizado con 162 pacientes intervenidos mediante RTU vesical, RTU prostática y adenomectomía láser entre octubre de 2008 y febrero de 2009, sin excluir a ningún paciente. A 66 pacientes se les administró un enema previo a la cirugía y a los restantes no. Analizamos la incidencia de infección urinaria (ITU), fiebre, retención aguda de orina, necesidad de enemas o laxantes durante el postoperatorio, contaminación del campo quirúrgico y la estancia media. Realizamos un análisis descriptivo, comparación de medias (t test) y chi cuadrado. Resultados: La edad media fue de 70,5 años (DS±10,62) y la estancia media fue de 4,8 días (DS±3,9). Un 6,2% de los pacientes tuvo ITU, un 3,1% tuvo fiebre, un 1,2% presentó retención aguda de orina y el 15,4% necesitó enemas o laxantes. Se recogió un caso de contaminación con heces del campo quirúrgico (0,6%). No se encontraron diferencias estadísticamente significativas para las variables analizadas entre ambos grupos de estudio. Conclusiones: En nuestra serie, la preparación intestinal mediante el empleo de enemas no ha demostrado utilidad para disminuir complicaciones durante el postoperatorio de cirugía endourológica (AU)
