Introduction:
One way how to reduce morbidity and improve cosmesic of kidney surgery is single site laparoscopy. Relatively well described concept but without defined position in clincal practise.
Aim:
To report of institutional experience with laparoendoscopic single-site surgery (LESS) nephrectomy (NE) and compare (matched case-control study) it with that of standard laparoscopic NE (LNE).
Material And Methods:
In the period 8/2011 to 10/2013, we performed 183 mini-invasive NE (132 tumours, 51 benign aetiology); 45 of them (24.6%) were LESS, the rest LNE. The main but not absolute indications for LESS were: non-obese men, and less advanced tumours. In 13 patients undergoing LESS-NEs (28.9%) there was a transumbilical approach. For the rest, a pararectal incision was performed and an accessory port was added in 31.1% (14) - 2/22 (9.1%) left sided, 12/23 (52.2%) right sided. Twenty-four LESS-NE were performed by a more experienced surgeon (mean operation time (MOT) 73.1 min), 21 LESS-NE by 4 other surgeons (MOT 132.8 min). These 24 were compared with 43 LNE done by the same surgeon before the period of LESS (1/2007-8/2011) and with similar characteristics of cases (body mass index (BMI) ≤ 35 kg/m(2), less advanced tumour).
Results:
We found no statistically significant differences in any of the parameters studied. The MOT 73.1 min vs. 75.0 min (p = 0.78), BMI 27.4 kg/m(2) vs. 29.2 kg/m(2) (p = 0.08), blood loss 54.7 vs. 39.2 (p = 0.47). Complications (4.2% vs. 11.6%) were only of internal character in origin. No conversion in either group. In LESS-NE, staplers were used more frequently (more expensive than clips) for division of renal hilar vessels (70.8% vs. 51.2%). The mean price of LESS-NE was €367 higher.
Conclusions:
The LESS NE performed by an experienced surgeon is a safe and efficient method for the surgical treatment of both malignant and benign renal conditions in patients with BMI < 30 kg/m(2) and with low-stage tumours. The LESS NE is more expensive compared to LNE.
