Abstract
Introduction

Open lumbar-aortic lymphadenectomy (OLAL) is the gold standard for treating post-chemotherapy retroperitoneal masses. Laparoscopic OLAL (L-OLAL) has emerged in recent years as an alternative for the handling of patients with these masses, with the additional potential benefits of minimal invasion.

Objective

To present our experience with the laparoscopic handling (L-OLAL) of residual post-chemotherapy masses in patients with advanced testicular cancer.

Materials and methods

Between 1993 and 2009, 43 patients underwent post-chemotherapy L-OLAL. A transperitoneal technique was employed in all patients. We assessed demographic, perioperational and pathological variables, as well as complications and follow-up.

Results

A unilateral dissection was performed in 17 patients, while 26 patients underwent a bilateral retroperitoneal dissection. In the first group, 4 patients relapsed. In the second group, there were no relapses. After an average follow-up of 21 months, the overall survival rate reached 95%. We recorded a rate of perioperative complications of only 9.3%.

Conclusions

In experienced hands, L-OLAL is a technically feasible surgical alternative for the treatment of patients who are carriers of advanced testicular cancer with residual post-chemotherapy masses. The dissection performed should be bilateral to avoid tumor relapses and increase the survival rate of these patients.

Resumen
Introducción

La linfadenectomía lumboaórtica abierta (LALA) es el estándar de oro en el manejo de masas retroperitoneales posquimioterapia. La LALA laparoscópica (LALA-L) ha surgido los últimos años como una alternativa para el manejo de estos pacientes, con los eventuales potenciales beneficios de la mínima invasión.

Objetivo

Exponer nuestra experiencia en el manejo laparoscópico (LALA-L) de las masas residuales posquimioterapia en pacientes con cáncer testicular avanzado.

Material y métodos

Entre los años 1993 y 2009 43 pacientes fueron sometidos a LALA-L posquimioterapia. Se utilizó una técnica transperitoneal en todos los pacientes. Se evaluaron variables demográficas, perioperatorias y patológicas, así como también las complicaciones y el seguimiento.

Resultados

En 17 pacientes se realizó una disección unilateral, mientras que 26 pacientes fueron sometidos a una disección retroperitoneal bilateral. Del primer grupo 4 pacientes recidivaron; el segundo grupo no presenta recidivas. Tras un seguimiento promedio de 21 meses la tasa de sobrevida global alcanza un 95%. Solo se registró un 9,3% de complicaciones perioperatorias.

Conclusiones

La LALA-L es una alternativa quirúrgica técnicamente factible, en manos experimentadas, en el tratamiento de pacientes portadores de un cáncer testicular avanzado con masas residuales posquimioterapia. La disección realizada debe ser bilateral en pro de evitar las recidivas tumorales y prolongar la tasa de sobrevida de estos pacientes.
