Nuevos avances en cirugía hepática: evaluación y planificación preoperatoria (Parte 1) / New advances in liver surgery: evaluation and preoperative planning

Resumen Los avances en la cirugía hepática de los últimos años han permitido resecciones hepáticas más extensa y complejas para el tratamiento de diferentes patologías del hígado sin un aumento excesivo de la morbimortalidad perioperatoria. El desarrollo de diferentes técnicas, tecnologías y herramientas para la evaluación preoperatoria han mejorado la planificación quirúrgica con el uso por ejemplo de las tecnologías audiovisuales e impresión de modelos en 3 dimensiones (3D) de alta fidelidad. Otros avances, han permitido realizar una mejor evaluación funcional del parénquima hepático y una caracterización más precisa de las lesiones con el uso por ejemplo de verde de indocianina, cintigrafía hepática y resonancia magnética con contraste hepatoespecífico. Este artículo describe algunos de los nuevos avances en la evaluación y planificación preoperatoria en cirugía hepática.

Advances in liver surgery in recent years have made it possible to achieve more extensive and complex liver resections for the treatment of different liver diseases without an excessive increase in perioperative morbidity and mortality. The development of different techniques, technologies and tools for preoperative evaluation have improved surgical planning with the use, for example, of audiovisual technologies and printing of high-fidelity 3-dimensional (3D) models. Other advances have allowed a better functional evaluation of the liver parenchyma and a more precise characterization of the lesions with the use, for example of indocyanine green or liver scintigraphy and magnetic resonance with hepatospecific contrast. This article describes some of the new advances in preoperative evaluation and planning in liver surgery.

Experience with the surgical treatment of hepatic hydatidosis: case series with follow-up.

AIM: To describe patient characteristics and the results of surgical treatment for hepatic hydatidosis (HH) in the Hospital Hernán Henríquez Aravena from December 2001 to March 2005. METHODS: Subjects older than 16 years with suspected HH were included based on the clinical picture and radiological studies. Variables examined included clinical and laboratory aspects, outcome, features of the parasite and surgical aspects. Descriptive statistics were used, calculating central tendency, dispersion and extreme tendency. RESULTS: The series was comprised of 122 patients, with an average age of 44 +/- 16.9 years. The most frequently used surgical technique was subtotal cystectomy in 90% of the patients, followed by hepatic resection (hepatectomy, segmentectomy and subsegmentectomy) in 5%. In 2%, a combination of subtotal cystectomy and segmentectomy was performed. In addition, 28% of the series presented complications in the postoperative period and mortality was 2%. CONCLUSION: The most frequently used surgical technique for HH was subtotal cystectomy and the morbidity and mortality rates in this Chilean series are comparable to other national and international series.
