Short Term Clinical Outcome after Laparoscopic Cryoablation of the Renal Tumor < or = 3.5 cm.

Journal Article (Journal Article)

Between September 2000 and September 2006, 26 patients underwent primary laparoscopic cryosurgical procedures (28) for an organ-confined renal tumor(s). In one case, cryosurgery was done sequentially on both kidneys. All patients had been carefully selected based on the following criteria: tumor size < or = 3.5 cm, the absence of local and systemic spread on cross-sectional computed tomography (CT) or magnetic resonance imaging (MRI), and the ability to tolerate general anesthesia. A pure laparoscopic approach was employed using third generation cryotechnology (Galil Medical Inc., Plymouth Meeting, USA). Patients were followed by serial CT or MRI scan, creatinine level, and physical examination at least every six months after cryotherapy. The mean patient age was 64 years (range: 44-79) and the mean follow-up was 20.9 +/- 17.2 months. The median tumor size was 2.0 cm (range: 1-3.5 cm). Only one patient required a blood transfusion and one patient developed a transient ileus. The median length of stay was 2.0 days (range: 0-9 days). The median change in creatinine was 0.1 mg/dl (range:-0.4 to 1.8). No patient was converted to open surgery. No evidence of recurrence or progression was found in all patients, and overall survival rate was 100%. Laparoscopic renal cryoablation of the small renal tumor is a safe procedure with minimal complications. Although there were no recurrences with short term follow-up, further long term study is needed to verify its efficacy.
