RESUMO
PURPOSE: We present the findings of 50 patients undergoing pure trans-umbilical laparo-endoscopic single-site surgery (LESS) living donor nephrectomy (LDN), between February 2010 and May 2014. MATERIALS AND METHODS: Laparo-endoscopic single-site surgery LDN was performed through an umbilical incision. Different trocars were used, namely Gelpoint (Applied Mιdical, Rancho Santa Margarita, CA) SILS port (Covidien, Hamilton, Bermuda), R-port (Olympus Surgical, Orangeburg, NY) and standard trocars, inserted through the same skin incision but using separate fascial punctures. The standard laparoscopic technique was employed. The kidney was pre-entrapped in a retrieval bag and extracted trans-umbilically. Data were collected prospectively including questionnaires containing patient reported oral pain medication duration and time to recovery. RESULTS: LESS LDN was successful in all patients. Mean warm ischemia time was 6.2 min (3-15), mean procedure time was 233.2 min (172-300), and hospitalization stay was 3.94 days (3-7) with a visual analogue pain score at discharge of 1.32 (0-3). No intraoperative complications occurred. The mean time of oral pain medication was 8.72 days (1-20) and final scar length was 4.06 cm (3-5). Each allograft was functional. CONCLUSION: Although challenging, trans-umbilical LESS LDN seems to be feasible and safe. Hence, LESS has the potential to improve cosmetic results and decrease morbidity.
