ABSTRACT
INTRODUCTION: Preoperative application of botulinum toxin type A has demonstrated to be safe and effective in the closure of complex ventral hernias in adults. However, its use in pediatrics has been little documented. CASE REPORT: We present the case of a 22-month-old girl with a complex abdominal wall ventral hernia secondary to multiple neonatal laparotomies. In a first procedure, botulinum toxin was administered using an intramuscular approach at six sites of the muscle layers surrounding the defect, under general anesthesia and ultrasound control. 4 weeks later, an open hernia repair was conducted, without complications. DISCUSSION: Botulinum toxin at low doses could facilitate the surgical treatment of complex ventral incisional hernias in children. Even though it is important to adjust dosage and anatomical reference points according to hernia type and patient age and weight, further studies are required to optimize these variables.
INTRODUCCION: La aplicación preoperatoria de toxina botulínica A ha demostrado ser segura y efectiva en el cierre de hernias ventrales complejas en adultos. Sin embargo, se ha documentado poco su uso en pediatría. CASO CLINICO: Se presenta el caso de una niña de 22 meses con una hernia de pared abdominal ventral compleja secundaria a múltiples laparotomías neonatales. En una primera intervención se administró por vía intramuscular toxina botulínica en seis puntos de las capas musculares alrededor del defecto bajo anestesia general y control ecográfico. Cuatro semanas después, se realizó una reparación abierta de la hernia, sin complicaciones. COMENTARIOS: La toxina botulínica a dosis bajas podría facilitar el tratamiento quirúrgico de hernias incisionales ventrales complejas en niños. Es importante ajustar la dosis y los puntos de referencia anatómicos según el tipo de hernia, la edad y el peso del paciente, aunque se requieren más estudios para optimizar estas variables.

It is essential to minimize exposure to ionizing radiation in children for various reasons. The risk of developing a tumor from exposure to a given dose of radiation is greater in childhood. Various strategies can be used to reduce exposure to ionizing radiation. It is fundamental to avoid unnecessary tests and tests that are not indicated, to choose an alternative test that does not use ionizing radiation, and/or to take a series of measures that minimize the dose of radiation that the patient receives, such as avoiding having to repeat tests, using the appropriate projections, using shields, adjusting the protocol (mAs, Kv, or pitch) to the patient's body volume, etc When contrast agents are necessary, intracavitary ultrasound agents can be used, although the use of ultrasound agents is also being extended to include intravenous administration. In fluoroscopy, contrast agents with low osmolarity must be used, as in CT where we must adjust the dose and speed of injection to the patient's weight and to the caliber of the peripheral line, respectively. In MRI, only three types of contrast agents have been approved for pediatric use. It is sometimes necessary to use double doses or organ-specific contrast agents in certain clinical situations; the safety of contrast agents for these indications has not been proven, so they must be used off label.
