Initial experience with LESS and hybrid LESS in patients with benign urologic disease

Abstract

We report our initial experience with 100 laparoendoscopic single site (LESS) and hybrid LESS procedures for benign urologic disease.Between December 2008 and April 2010, we performed LESS and hybrid LESS urologic procedures in 100 cases for various benign urologic diseases. Conversion to standard laparoscopy was necessary in six cases, conversion to hand-assisted laparoscopic surgery occurred in one case, and conversion to open surgery was necessary in one case. Intra- and postoperative complications occurred in nine and four cases, respectively. Totally, the mean operative time was 170 minutes, the mean blood loss was 221 ml, and the mean hospital stay was 5.1 days. The mean patient controlled anesthesia (PCA) equivalents used were 81.5 ml and the mean Visual Analog Pain Scale (VAPS) scores at postoperative day 1 and discharge were 3.8 and 2.1, respectively. The study was limited by retrospective design and short-term follow-up periods. LESS and hybrid LESS procedures are technically feasible in a variety of ablative and reconstructive applications of benign urologic diseases. However, apparent benefits of LESS surgical techniques over conventional laparoscopy are needed to be further explored.
