BACKGROUND: Gasless laparoendoscopic single-port surgery (GasLESS) for radical nephrectomy (GasLESSRN) in the flank position is a minimally invasive treatment option for patients with T1-3 renal cell carcinoma (RCC).
However, RCC patients considered suitable for supine positioning rather than flank positioning for radical nephrectomy are occasionally encountered. This study evaluated the safety and feasibility of approach via a small retroperitoneal anterior subcostal incision (RASI) in the supine position for GasLESSRN (RASI-GasLESSRN) on the basis of our initial experience.
METHODS: RASI-GasLESSRN was performed on 42 patients with RCC or suspected RCC from 2011-2013. The RASI, which was 6 cm long in principle, was made parallel to the tip of the rib from the lateral border of rectus abdominis muscle toward the flank in the supine position. The specimen was extracted via the RASI using a retrieval device. All procedures were performed retroperitoneally under flexible endoscopy with reusable instruments and without carbon dioxide insufflation or insertion of hands into the operative field.
RESULTS: RASI-GasLESSRN was successfully performed in all patients without complications. The mean incision length was 6.3 cm, mean operative time was 198 minutes, and mean blood loss was 284 mL. All 42 patients were classified as Clavien grade I. The mean times to oral feeding and walking were 1.1 and 2 days, respectively. The mean number of postoperative days required for patients to be dischargeable was 3.7 days.
CONCLUSIONS: The approach via a small RASI in the supine position for GasLESSRN is a safe and feasible technique. RASI-GasLESSRN in the supine position is an alternative minimally invasive treatment option, especially for RCC patients considered suitable for supine positioning.
