BACKGROUND: Laparoendoscopic single-site surgery (LESS) allows for the performance of major urologic procedures with a single small incision and minimal scarring. The da Vinci Surgical System provides advantages of easy articulation and improved ergonomics; however, an ideal platform for these procedures has not been identified. OBJECTIVE: To evaluate the GelPort laparoscopic system as an access platform for robotic LESS (R-LESS) procedures. DESIGN, SETTING, AND PARTICIPANTS: Since April 2008, 11 R-LESS procedures have been completed successfully in a single institutional referral center. For the last four consecutive cases, the GelPort has been used as an access platform through a 2.5-5-cm umbilical incision. INTERVENTION: R-LESS cases performed with the GelPort included pyeloplasty (n=2), radical nephrectomy (n=1), and partial nephrectomy (n=1). MEASUREMENTS: Perioperative data were obtained for all patients including demographic data, operative indications, operative records, length of stay, complications, and pathologic analysis. RESULTS AND LIMITATIONS: For both pyeloplasty cases, average operative time (OR time) was 235 min and estimated blood loss (EBL) was 38 cm(3). For the patient undergoing radical nephrectomy for a 5.1-cm renal tumor, OR time was 200 min and EBL was 250 cm(3). The final patient underwent partial nephrectomy without renal hilar clamping for an 11-cm angiomyolipoma with OR time of 180 min and EBL of 600 cm(3). All R-LESS procedures attempted with the GelPort were completed successfully and without complication. Average length of hospital stay was 1.75 d (range: 1-2). The partial nephrectomy patient required transfusion of 1 U of packed red blood cells. CONCLUSIONS: Use of the GelPort as an access platform for R-LESS procedures provides adequate spacing and flexibility of port placement and acceptable access to the surgical field for the assistant, especially during procedures that require a specimen extraction incision. Additional platform and instrumentation development will likely simplify R-LESS procedures further as experience grows.
