Abstract
Objective

Peritoneal carcinomatosis associated with renal cell carcinoma is an infrequent entity, usually associated with large renal masses, and with a very rare presentation after surgery of localized renal tumors. Our objective is to review the literature and analyze the factors involved in the development of peritoneal carcinomatosis after laparoscopic partial nephrectomy in localized tumors.

Material and methods

We present our experience with two cases of peritoneal carcinomatosis after laparoscopic partial nephrectomy. We reviewed the literature and analyzed the factors associated with the development of peritoneal carcinomatosis after laparoscopic partial surgery in renal cell carcinoma.

Results

Between 2005–2018, 225 patients underwent laparoscopic partial nephrectomy for localized renal neoplasia in our service. Two patients developed peritoneal carcinomatosis during follow-up, at 1.5 and 7 years after surgery. Few cases of postoperative peritoneal carcinomatosis for renal neoplasia have been described in the literature, being more frequently associated with large renal masses, with multiple metastases at diagnosis, with a poor prognosis. The dissemination of tumor cells during surgery, direct tumor extension or metastasis by hematogenous route, are among the factors involved in the development of this condition.

Conclusions

Peritoneal carcinomatosis after laparoscopic partial nephrectomy constitutes a very rare event. However, it should be taken into consideration, and, since it is the only factor we can influence, we must maximize precautions during the surgical act, following oncological principles.

Resumen
Objetivo

La carcinomatosis peritoneal asociado al carcinoma de células renales es una entidad infrecuente, normalmente asociada a grandes masas renales, siendo muy rara su presentación tras cirugía de tumores renales localizados. Nuestro objetivo es revisar la literatura y analizar los factores implicados en el desarrollo de carcinomatosis peritoneal tras nefrectomía parcial laparoscópica, en tumores localizados.

Material y métodos

Presentamos nuestra experiencia con dos casos de carcinomatosis peritoneal tras cirugía parcial laparoscópica. Realizamos revisión de la literatura y analizamos los factores asociados al desarrollo de carcinomatosis peritoneal tras cirugía parcial laparoscópica en carcinoma de células renales.

Resultados

Entre 2005-2018, 225 pacientes fueron sometidos a nefrectomía parcial laparoscópica, por neoplasia renal localizada, en nuestro servicio. Dos pacientes desarrollaron carcinomatosis peritoneal en el seguimiento, uno al año y medio de la cirugía y un segundo caso, a los siete años. Pocos casos de carcinomatosis peritoneal tras cirugías de neoplasia renal han sido descritos en la literatura, estando más frecuentemente asociado a grandes masas renales, con múltiples metástasis al diagnóstico, siendo el pronóstico infausto. Entre los factores implicados en su desarrollo pueden ser la diseminación de células tumorales durante la cirugía, extensión tumoral directa o metástasis por vía hematógena.

Conclusiones

La carcinomatosis peritoneal tras nefrectomía parcial laparoscópica constituye un evento muy raro, pero que debe ser tenido en cuenta y, dado que es el único factor en el que podemos influir, extremar al máximo las precauciones durante el acto quirúrgico, siguiendo los principios oncológicos.
