title: Outcomes of open splenectomy for hematologic malignancy with splenomegaly: a contemporary perspective.
abstract: Splenectomy for hematologic malignancy (HM) is considered a high-risk procedure, especially in cases of splenomegaly. We analyzed the postoperative course of 82 patients undergoing open splenectomy for HM-related splenomegaly (splenic craniocaudal length 15 cm or greater) in a high-volume center. Primary outcome measures were: perioperative clinical course, rate and severity of postoperative complications (Clavien-Dindo classification), and length of hospital stay. Risk factors analyzed for morbidity and mortality by logistic regression analysis were: gender, age, American Society of Anesthesiologists (ASA)grade, body mass index (BMI), steroidal treatment, preoperative white blood cell count, spleen size, spleen weight, and operative time. The postoperative mortality rate was 1.2 per cent. Only 15.9 per cent of patients required surgical, endoscopic, or radiological intervention after splenectomy (Grade 3 or greater complication). Overall postoperative morbidity rate (as Grade 2 or greater complication) was 52.4 per cent. Surgical complications, mainly bleeding, occurred in 40.2 per cent of patients and 32.9 per cent of patients required blood transfusion. Medical complication rate was 24.4 per cent. Pulmonary disorders were prevalent among medical complications. At multivariate analysis, only ASA score was an independent risk factor for postoperative complications. Open splenectomy can be performed in high-volume centers with low mortality and acceptable morbidity in patients with HM-related splenomegaly, provided that patients at highest risk of postoperative complication (ASA greater than 3) are carefully evaluated.
