Abstract:
Objective To report a 4-year cumulative series (209 cases) of laparoendoscopic singlesite surgery (LESS) in urology and assess its clinical utilization. Methods Consecutive LESS cases done between December 2008 and July 2012 at our institution were prospectively recorded and retrospective analyzed in this study.Demographic data,main perioperative outcomes,and information related to the surgical technique were collected and analyzed.There were 209 patients ( 121 males and 88 females) with a mean age of (52.8 ±14.5) years,a mean B MIof (23.5 ±3.12) kg/m2 and a mean ASA score of (2.0±0.3).20.1％ (42 cases) of patients had previous abdominal or pelvic surgeries.29.2％ (61 cases) and 12.9％(27 cases) of patients had diabetes mellitus and hypertension. Indications were renal tumors (70 cases,33.5％),adrenal tumors (42,20.1％),renal cyst (22 cases,10.5％),ureteral calculi (22 cases,10.5％),nonfunctional kidneys (19 cases,9.1％),BPH (10 cases,4.8％),and others (24 cases,11.5％ ).Surgical conversions were evaluated,as well as intraoperative and postoperative complications.Two periods were arbitrarily dcfined:the first was from December 2008 to Septcmber 2010 (22 mon) and the second.was from October 2010 to July 2012 (22 mon).A comparative analysis between these two periods was conducted. Results There were 209 LESS surgeries included in this study.Most common procedures ( 92.3％ ) were done on the upper urinary tract,with 55.5％ of the whole cohort being tumor-related indications and only 16.3％ being reconstructive procedures.The transperitoneal approaches were preferentially adopted in 80.9％ cases,and transvesical access in 5.3％ cases. The transumbilical access was used in 46.9％ of cases.The overall conversion rate was 8.1％,with 4.3％ of cases converted to reduced - port laparoscopy,1.9％ to conventional laparoscopy,and 1.9％ to open surgery.The intraoperative complication rate was 4.8％ ( 10/209 ) and postoperative complications,mostly low grade,were encountered in 11.5％(24/209) of cases.There was a significant increase in the number of LESS cases during the second study period; the rate of some procedures (ie,transumbilical LESS,renal cyst decortication and transvesical single-port enucleation of the prostate) was lower,whereas some other procedures were performed more frequently (ie,tumor-related LESS procedures,radical nephrectomy and adrenalectomy). Conclusions A broad range of urological procedures can be finished with LESS technique in the experienced hands of a laparoscopic surgeons.However,LESS is still in its infancy with a certain risk of surgical complication and conversion.Stringent patient selection criteria should be applied,especially during the learning curve.Complex reconstructive procedures or malignant tumor related indications are not appropriate as the start of this kind of procedure.We need always put patient's safety and treatment efficacy first.
