Resumen

La cistoprostatectomía radical es el tratamiento de elección para el cáncer vesical infiltrante. En los últimos años las indicaciones de sustitución vesical se han ampliado debido a las ventajas que aportan sobre otros tipos de derivaciones siendo la neovejiga ileal descrita por Hautmann una de las más utilizadas. Posteriormente se han descrito diversas modificaciones de la técnica original como la utilización de un segmento de asa sin detubulizar a modo de chimenea a la cual se anastomosan los uréteres. Presentamos una variante técnica de la neovejiga de Hautmann utilizando dos “chimeneas” anastomosando cada uréter a la luz previamente abierta de cada asa espatulando el uréter a modo de “palo de golf” para adaptar los calibres. Entre las ventajas de este tipo de anastomosis destacan la utilización de segmentos ureterales más cortos adaptando la longitud del asa lo que posibilita una anastomosis sin tensión y minimiza la isquemia disminuyendo por tanto la aparición de fístulas y estenosis. No precisa la reali ación de enterotomías adicionales y se facilita el acceso a cada anastomosis por separado en caso de necesidad de reintervención.

Abstract

Radical cystoprostatectomy is accepted as the standard treatment for muscle-invasive bladder cancer. During last years the indications for orthotopic neobladders have increased due to their advantages over other kind of diversions. Hautmann neobladder is one of the most commonly used. Several modifications have been later described. For example, after perform the W-shape pouch ureters can be anastomosed to a not-detubularized bowel segment (chimney modification). Here is described a modification of the Hautmann neobladder with two chimneys. Each ureter is spatulated in a golf club manner and anastomosed to the open end of each bowel loop. This kind of anastomosis provides several advantages. It is possible to use shorter ureteral segments by increasing the length of bowel used. It allows an anastomosis without tension, and less ischemia, so the risk of stenosis and fistula is decreased. It is not necessary to perform additional enterothomies and in case of reintervention it is easier to access each anastomosi without damaging the other one.
