Abstract

OBJECTIVE:: To evaluate long-term outcomes after splenectomy for massive splenomegaly in a series of 222 consecutive patients. BACKGROUND:: Splenectomy for massive splenomegaly (>1500 g) provides palliation but is associated with a high rate of perioperative complications in a population of patients with advanced hematological malignancies. Predictive factors for survival and whether the palliative goals are achieved in the long-term are not well defined. METHODS:: Patients with various hematological disorders who underwent splenectomy between 1998 and 2009 were followed until death or for at least 2 years. Linear and logistic regression analyses were used to ascertain the impact of demographical factors, diagnoses, and preoperative transfusion parameters on the postoperative survival. RESULTS:: Splenectomy for massive splenomegaly was performed most commonly for non-Hodgkin lymphoma (48%) and myeloid metaplasia (31%). Mean ± standard deviation splenic weight was 2731 ± 1393 g (range, 1500-13,085 g). Average operating time was 115 minutes, with a range from 46 to 346 minutes. Thirty-day mortality was 1.8%, and the complication rate was 20%. The most common complications were hemorrhage (9%) and portal venous thrombosis (9.9%). Relief from pressure-related symptoms was achieved in 98.5%, and durable remission of anemia and thrombocytopenia persisted in half of the patients at 2 years. Sex, age, and intraoperative blood loss were not significantly associated with survival. Preoperative need for red blood cell and platelet transfusions were the most significant risk factors associated with decreased survival. CONCLUSIONS:: Splenectomy for massive splenomegaly can be performed safely and offers durable palliation. Preoperative transfusion requirement is an indicator of hematological disease severity and predictor of decreased survival.
