Splenectomy as part of cytoreductive surgery for ovarian carcinoma

Splenectomy is sometimes necessary to achieve optimal cytoreduction or manage iatrogenic injury in the surgical management of epithelial ovarian cancer (EOC) and related conditions. To determine the place of splenectomy in cytoreductive surgery a retrospective review was made of patient hospital records. Between April 1989 and August 1994, 18 patients were found to have undergone a splenectomy as a component of their surgery leading to optimal debulking. Morbidity attributable to the splenectomy was minimal, with no significant increase in operative time or blood loss. The morbidity attributable to the splenectomy was as follows: atelectasis and/or effusion (8), pancreatic tail injury (4), thrombocytosis > 10(6)/microliters (3), pancreatic pseudocyst (1), partial left adrenalectomy (1), and pulmonary embolism (1). There were no instances of overwhelming postsplenectomy infection. Five patients were anticipated to require splenectomy and may have benefitted from preoperative vaccination against potential pathogens. Three patients were found to have splenic parenchymal metastases. Consistent with the international literature, these patients had other features consistent with stage IV disease, recurrent disease, or poor survival. Consideration should be given to expanding the FIGO stage IV classification to include splenic parenchymal disease. Splenectomy is a feasible and safe procedure to facilitate optimal tumor debulking; however, the potential associated morbidity mitigates against this procedure if significant, suboptimal residual disease is left elsewhere.
