Abstract
Introduction

Many surgeons use intraoperative frozensection biopsy of thyroid nodules to confirm malignant disease, but it continues to generate considerable controversy. We reviewed our recent experience to determinate the clinical utility of frozen section in our surgical management and intraoperative decision-making.

Patients and method

All patients who had operations for thyroid nodular disease between 2000 and 2006 were included in this retrospective study. We compared the results of frozen-section diagnosis and definitive histological results in a population of 212 patients.

Results

Frozen sections was false negative in 3 patients (1.66%) and false positive in 1 (0.47%) and avoided 12 reoperations (5.6%). When there was no suspicious malignant disease had a sensitivity of 0.75%. In the group of follicular disease the sensitivity was 3.7% and in the group with suspicious malignant disease was 37.5%.

Conclusions

Frozen section was more helpful in the group of suspicious for malignant disease. It does not seem to be necessary when fine-needle biopsy indicates benign or follicular disease.

Resumen
Introducción

Muchos cirujanos utilizan la biopsia intraoperatoria de los nódulos tiroideos para confirmar malignidad, pero continúa generando bastante controversia. Hemos revisado nuestra experiencia reciente para determinar la utilidad clínica de la biopsia extemporánea en la toma de decisiones intraoperatorias.

Pacientes y método

Se incluyó en este estudio retrospectivo a todos los pacientes sometidos a una cirugía tiroidea por nódulo tiroideo entre 2000 y 2006. Comparamos los resultados de la biopsia introperatoria con los de la anatomía patológica definitiva en una población de 212 pacientes.

Resultados

La biopsia extemporánea tuvo un resultado falso negativo en 3 (1,67%) pacientes y falso positivo en 1 (0,47%). Evitó 12 (5,6%) reintervenciones. Cuando no hubo sospecha previa de malignidad, su sensibilidad fue del 0,75%. En el grupo de lesiones foliculares su sensibilidad fue del 3,7% y en el sospechoso de malignidad del 37,5%.

Conclusiones

La biopsia extemporánea fue más útil en el grupo con sospecha de malignidad. No parece ser necesaria cuando la punción-aspiración con aguja fina indica que es benigna o de tipo folicular.
