Feasibility and safety of conventional laparoscopic instruments in laparoendoscopic single-site (LESS) surgery: Experience with one hundred cases

Abstract

Background and purpose: To evaluate the feasibility and safety of conventional laparoscopic instruments in common urological laparoendoscopic single-site (LESS) procedures. Methods: From 2008 to 2010, we retrospectively reviewed prospectively collected data from 100 patients who underwent LESS procedures by a single surgeon for various common urological indications. The LESS operations included adrenalectomy (n = 15), radical nephrectomy (n = 3), radical nephroureterectomy with bladder cuff resection (n = 5), varicocelectomy (n = 12), nephropexy (n = 4), lumbar sympathectomy (n = 4), and adult hernia mesh repair (n = 57). Results: All procedures were completed successfully without ancillary ports or articulating instruments, except in two cases that required laparoscopic conversion. The mean patient age was 48.9 years, and the mean body mass index was 23.8. The mean operative time was 99.7 minutes, the mean estimated blood loss was 17.3. mL, and the mean hospital stay was 2.1 days. No intra-operative complication occurred. Conclusion: Our experience revealed that the usage of conventional laparoscopic instruments is feasible and safe in common urological LESS procedures. © 2011.
