RESUMO

BACKGROUND: The incidence of papillary thyroid microcarcinoma (PTMC) is increasing. OBJECTIVE: To analyze the long-term prognosis of PTMC. METHOD: Study population: patients with a histopathological diagnosis of PTMC (size ≤ 1 cm) treated according to the risk of recurrence of the Latin American Thyroid Society. Inclusion criteria: minimum follow-up of 2 years, availability of histopathological samples, and treatment compliance. Exclusion criteria: previous thyroid surgery, other synchronous malignancies or ectopic location of the PTMC. Study variables: persistences, recurrences and mortality. RESULTS: Based on the risk of recurrence, PTMC has very low risk in 65.2% (n = 105), low risk in 17.4% (n = 28) and high risk in 17.4% (n = 28). In high risk patients, total thyroidectomy was performed in all cases, cervical lymphadenectomy in 57,1% (n = 16) and metabolic therapy with I131 in all cases. During a mean follow-up of 119,8 ± 65 months, 0.6% (n = 1) of recurrences took place. Risk factors associated to recurrence were not identified. No patient died due to MCPT. CONCLUSIONS: PTMC treated based on its risk of recurrence has a good long-term prognosis, without persistences, with a low number of recurrences and absence of disease-associated mortality.


ANTECEDENTES: La incidencia del microcarcinoma papilar de tiroides (MCPT) está aumentado. OBJETIVO: Analizar el pronóstico a largo plazo del MCPT. MÉTODO: Población a estudio: pacientes con diagnóstico histopatológico de MCPT (tamaño ≤ 1 cm) tratados según el riesgo de recurrencia de la Sociedad Latinoamericana de Tiroides. Criterios de inclusión: seguimiento mínimo de 2 años, disponibilidad de las muestras histopatológicas y cumplimiento del tratamiento. Criterios de exclusión: cirugía tiroidea previa, otras patologías malignas sincrónicas o localización ectópica del MCPT. Variables a estudio: persistencias, recidivas y mortalidad. RESULTADOS: Según el riesgo de recurrencia, el 65.2% (n = 105) tuvo muy bajo riesgo, el 17.4% (n = 28) bajo riesgo y el 17,4% (n = 28) alto riesgo. En los pacientes de alto riesgo se realizó tiroidectomía total en todos los casos, linfadenectomía cervical en el 57,1% (n = 16) y terapia metabólica con I131 en todos los casos. Durante un seguimiento medio de 119,8 ± 65 meses hubo un 0,6% (n = 1) de recurrencias. No se evidenciaron factores de riesgo asociados a recidiva de la enfermedad. Ningún paciente falleció debido al MCPT. CONCLUSIONES: El MCPT tratado en función del riesgo de recurrencia tiene un buen pronóstico a largo plazo, sin persistencias, con una baja cifra de recurrencias y ausencia de mortalidad debida a la enfermedad.

RESUMO

Introducción Tras 20 años de experiencia en cirugía hepática laparoscópica, aún no están bien definidos el mejor abordaje (totalmente laparoscópico [CTL] o asistido con la mano [CLA]), indicaciones quirúrgicas, posición, instrumentación, resultados postoperatorios inmediatos y a largo plazo, etc. Objetivo Presentar nuestra experiencia en resecciones hepáticas laparoscópicas (RHL).Pacientes y método En 10 años hemos realizado 132 RHL en 129 pacientes: 112 tumores malignos (90 metástasis hepáticas; 22 tumores malignos primarios) y 20 lesiones benignas (18 tumores benignos; 2 quistes hidatídicos). Veintiocho casos se realizaron por CTL y 104 por CLA. Técnica quirúrgica: 6 hepatectomías derechas (2 como segundo tiempo de una resección hepática en 2 tiempos); 6 hepatectomías izquierdas; 9 resecciones de 3 segmentos; 42 resecciones de 2 segmentos; 64 resecciones de un segmento y 5 casos de resecciones locales. Resultados No existió mortalidad perioperatoria. Morbilidad: 3%. Con CTL se completó la resección en 23/28 casos, mientras que con CLA se completó en los 104 casos. Transfusión 4,5%; tiempo quirúrgico 150 min y estancia media de 3,5 días. La supervivencia a 1, 3 y 5 años de los tumores malignos primarios fue del 100, 86 y 62%, mientras que la supervivencia de las metástasis colorrectales fue del 92, 82 y 52%, respectivamente. Conclusión La RHL, tanto por CTL como por CLA, en casos seleccionados, reproduce los resultados de la cirugía abierta (morbimortalidad y supervivencia a 5 años similares), con las ventajas de la cirugía mínimamente invasiva (AU)


Introduction After 20 years of experience in laparoscopic liver surgery there is still no clear definition of the best approach (totally laparoscopic [TLS] or hand-assisted [HAS]), the indications for surgery, position, instrumentation, immediate and long-term postoperative results, etc. Aim To report our experience in laparoscopic liver resections (LLRs).Patients and method Over a period of 10 years we performed 132 LLRs in 129 patients: 112 malignant tumours (90 hepatic metastases; 22 primary malignant tumours) and 20 benign lesions (18 benign tumours; 2 hydatid cysts). Twenty-eight cases received TLS and 104 had HAS. Surgical technique: 6 right hepatectomies (2 as the second stage of a two-stage liver resection); 6 left hepatectomies; 9 resections of 3 segments; 42 resections of 2 segments; 64 resections of one segment; and 5 cases of local resections. Results There was no perioperative mortality, and morbidity was 3%. With TLS the resection was completed in 23/28 cases, whereas with HAS it was completed in all 104 cases. Transfusion: 4,5%; operating time: 150 min; and mean length of stay: 3,5 days. The 1-, 3- and 5-year survival rates for the primary malignant tumours were 100, 86 and 62%, and for colorectal metastases 92, 82 and 52%, respectively. Conclusion LLR via both TLS and HAS in selected cases are similar to the results of open surgery (similar 5-year morbidity, mortality and survival rates) but with the advantages of minimally invasive surgery (AU)
