Biopsia guiada por laparoscopia de tumoraciones intraabdominales no digestivas.

Abstract

esumen Introducción. La laparoscopia es un recurso diagnóstico de múltiples enfermedades que requieren biopsia de masas intraabdominales no abordables mediante punciones guiadas por imagen. Evita la morbimortalidad asociada a la laparotomía favoreciendo el tratamiento precoz de los procesos malignos. Pacientes y método. Análisis descriptivo, retrospectivo de los resultados de una serie de pacientes de nuestro hospital, que presentan nódulo intraabdominal de etiología desconocida biopsiados mediante cirugía laparoscópica desde enero de 2001 hasta mayo de 2006. Ninguno de los pacientes es candidato a punción percutánea guiada por imagen. Resultados. Realizamos 23 biopsias: 8 retroperitoneales (34,7%), 5 mesentéricas (21,7%), 5 en hilio hepático, 4 pelvianas y 1 en cadena de vena ilíaca y asociamos 5 biopsias complementarias. Se obtuvo un 100% de material suficiente para diagnóstico anatomopatológico. La duración media de la intervención fue de 71 min. El 61% tuvo un ingreso menor de 24 h.

ntroduction. Laparoscopic surgery offers an alternative diagnostic technique in multiple diseases requiring biopsy of non-digestive intra-abdominal masses in which image-guided biopsy cannot be performed. Laparoscopic biopsy aims to reduce the surgical aggression and complications associated with laparotomy and favors the early treatment of malignancies. Patients and method. We performed a retrospective descriptive study of our results in a series of patients in our hospital with intra-abdominal masses of unknown etiology who underwent laparoscopic surgery between January 2001 and April 2006. None of the patients were candidates for image-guided percutaneous biopsy. Results. We carried out 23 biopsies: 8 retroperitoneal (34.7%), 5 mesenteric (21.7%), 5 hepatic, 4 pelvic, and 1 in the iliac chain, as well as 5 complementary biopsies. In all patients, sufficient material for histologic diagnosis was obtained. The mean operating time was 71 minutes. Length of hospital stay was less than 24 hours in 61% of the patients. The median length of hospital stay was 1.5 days. Conclusions. The laparoscopic approach allows complete visualization and examination of the entire peritoneal cavity. Laparoscopic biopsy is a safe and effective procedure with excellent patient recovery and allows early definitive treatment.
