Pd08-06 comparing Outcomes for Renal Angiomyolipoma Treated With Embolization, Ablation or Surgery

Abstract

INTRODUCTION AND OBJECTIVE: Laparoscopic Cryoablation (LC) is commonly indicated for anterior renal mass or those nearby vital structures. Reports describing early postoperative (postop) morbidity are rare. We used the National Surgical Quality Improvement Program (NSQIP) data in patients with renal mass to evaluate early postop complications related to LC and to determine the preoperative (preop) factors associated with any complication.METHODS: Using 2007-16 NSQIP, patients who received LC for renal mass were identified. Information on demographics, comorbidities, preop labs, operating time (OPTIME), length of stay (LOS), and postop complications 30 days were extracted. The presence of any of the extracted complications was used to create a variable for "any complication" and the presence of either superficial or deep surgical site infection (SSI), organ space SSI, or wound disruption was used to indicate "any wound occurrence." Univariate analysis described the proportions of patients with complications, and a multivariable logistic regression determined preop factors associated with any complication.RESULTS: A total of 250 patients with average age of 68 years (SD[11) were identified. Most were males (62%) and Caucasians (75%) while some were current smoker (18%), obese (47%), functionally dependent (4%), and had metastatic cancer (2%). Most common comorbidities were hypertension (76%) and diabetes (24%). Most had a preop hematocrit level <45% (88%). Mean LOS was 3.6 days (SD [4.8) and mean OPTIME was 141 minutes (SD[58). The proportions of patients with early postop mortality was 0.8%, any complication was 12%, and any wound occurrence was 0.8%. Most frequent complications were blood transfusion (4%), urinary tract infection (3%), return to OR (2%), unplanned intubation (1%) and cerebrovascular accident (1%). Of 128 patients with data on readmissions, 5% were readmitted.
