AIM: To review an evolution of laparoscopic surgery, there has been a growing interest in laparoendoscopic single-site surgery (LESS).
METHODS: A comprehensive electronic literature search was conducted using PubMed database to identify all publications relating to LESS-partial nephrectomy (PN). The research includes articles published from April 2008 to January 2014. We focused our attention only on articles in which were cited the single-site surgical technique (laparoscopic and robotic), tumour stage and grade, mean tumour size, intraoperative variables, blood loss and transfusion rate, length of post-operative stay and complication rates, Clavien classification, positive of surgical margins, pain assessment at discharge.
RESULTS: A total of 9 studies were collected with 221 patients included. The mean patients age was 62 years. The mean tumor size was 2.35 cm with a mean operative time of 181 min (range 111-270 min) and 58.3% were done by robot. The mean ischemia time was 23.6 min. The 25.8% of patients underwent an unclamp LESS-PN. Mean estimated blood loss was 296 mL and median length of hospital stay was 4 d. The rate of severe post-operative complications (≥ Clavien grade III) was 5.4%. Not all surgical series of LESS-PN or Robotic-LESS-PN shows conversion in Multiport Laparoscopic or Open Surgery. Regarding oncologic outcomes, surgical margins were positive 4% of patients (9/221), no distant or port-site metastases were recorded.
CONCLUSION: LESS-PN and RLESS-PN are feasible and associated with reduced postoperative pain, shorter median hospital stay, shorter recovery time, and better cosmetic satisfaction without compromising surgical and oncological safety.
Core tip: In recent years, there has been a growing interest in laparoendoscopic single-site surgery (LESS). Some authors has used da Vinci surgical system for LESS surgery. Although almost every laparoscopic procedure in urology has been duplicated by using a LESS approach, only a few studies have reported problems and challenges encountered during LESS partial nephrectomy. The aim of our study is to evaluate the current literature in order to assess the efficiency, safety, and potential advantages of LESS-partial nephrectomy and Robotic-LESS PN.
