Omentalization of cystic sublumbar lymph node metastases for long-term palliation of tenesmus and dysuria in a dog with anal sac adenocarcinoma

Anal sac adenocarcinoma commonly metastasizes to the sublumbar lymph nodes early in the disease and may cause tenesmus and dyschezia in affected dogs. Omentalization can provide a continuous source of drainage for fluid-filled abdominal cysts while reducing development of infection, inflammation, and cyst adhesion to surrounding organs. Although omentalization is not a routine treatment for metastatic adenocarc inoma, it may be helpful in palliating clinical signs of disease associated with cystic metastatic masses.
