Abstract
OBJECTIVES: To assess the feasibility, operative morbidity and oncological outcome of laparoendoscopic single-site (LESS) radical cystectomy. PATIENTS AND METHODS: Ten patients with clinical stage T1-T2 bladder cancer underwent a LESS radical cystectomy. The mean (SD) age of the patients was 64.8 (8.6) years and their mean body mass index was 25.9 (2.7) kg/m(2). The procedure was done via a single-incision laparoscopic surgery port using a rigid 5-mm 30° long-shaft laparoscope in addition to the two working instruments. A 7-cm Pfannenstiel incision was made to remove the specimens and to allow the creation of an ileal neobladder with hand assistance. RESULTS: In eight patients the LESS radical cystectomy was completed as scheduled, with the other two requiring a conversion, one to an open procedure due to locally advanced disease, and the other to conventional laparoscopy due to gas leakage. The mean (SD) operative duration was 236 (49) min, with a mean estimated blood loss of 575 (113) mL, and a mean hospital stay of 5.5 (0.7) days. No postoperative analgesic medications were prescribed and patients returned to normal activity after a mean (SD) of 17.6 (2.6) days. The pathological examination showed negative surgical margins for the bladder specimens, with a mean (SD) of 14 (1.9) lymph nodes retrieved. Seven patients were cancer-free within a mean (SD, range) follow-up of 37 (6, 29-44) months. CONCLUSIONS: LESS radical cystectomy is technically feasible, with a favourable course and convalescence, and it has an acceptable oncological outcome.
