Single-incision laparoscopic surgery and conventional laparoscopic treatment of varicocele in adolescents: Comparison between two techniques

Background: Single-incision laparoscopic surgery (SILS) has gained great popularity in paediatric surgery due to its minimally invasive approach and improved cosmetic results. Notwithstanding, reports describing its adoption in children are still fragmentary and some perplexities have been raised by some surgeons. We reviewed our experience with the SILS Palomo varicocelectomy procedure (SIL-V) in children and adolescents, comparing this group with a similar series operated using conventional laparoscopic varicocelectomy (CL-V). Patients and Methods: A total of 69 Palomo laparoscopic varicocelectomies were performed in patients aged 11-17 years from January 2011 to January 2013. Indications for surgery included grades II-III varicocele or ipsilateral testicular hypotrophy. The SIL-V procedure was performed in 44 patients with roticulating and conventional 5 mm instruments. Testicular vessels were isolated “en bloc,” clipped and cut. Operating time, visual analogue scale and post-operative results were compared to a similar group of 25 patients operated with CL-V.Results: No patient of the SIL-V group required conversion to conventional laparoscopy, none to open surgery. Mean operative time was 22 min (range: 19-28) in the SIL-V group, not signifi cantly different compared with CL-V (mean 21 min, range: 18-25). All patients experienced a smooth recovery from surgery without any complications, and were discharged on day 1. No diffi culties were found in the SIL-V group. The post-operative pain score was signifi cantly better in SIL-V. Conclusion: The SIL-V procedure is safe and effective and allows a fast and effi cient isolation of the vascular bundle. The use of conventional instruments is technically feasible in SIL-V.Key words: Palomo, single-incision laparoscopic surgery, varicocel
