Splenectomy in high-risk patients with splenomegaly

BACKGROUND: Splenectomy in patients with massive splenomegaly and hematologic malignancy results in higher morbidity and mortality with primarily palliative benefit. METHODS: From a 14-year experience with 172 splenectomies, the perioperative course of 39 high-risk patients with splenomegaly was reviewed for comorbidities, indications, complications, and mortality. RESULTS: Twenty-three males and 16 females with a mean age of 54.2 years and a mean 12.8-day postoperative length of stay were reviewed. Sixteen patients (41%) had 23 major complications related to age (P = 0.047) and operative time (P = 0.01). Intraoperative transfusion was related to splenic size (P = 0.04), and estimated blood loss (P = 0.02) was inversely related to use of splenic artery preligation. Three perioperative deaths were secondary to sepsis and multi-organ system failure. CONCLUSION: Splenomegaly and comorbidities of the primary disease result in higher morbidity and mortality. Splenic artery preligation is valuable to limit intraoperative blood loss and facilitate splenectomy.
