          Abstract

          Desde el año 2007 se están realizando distintos procedimientos en cirugía laparoendoscópica por puerto único (laparoendoscopic single-site surgery), incluyendo nefrectomía, pieloplastia, adenomectomía prostática y, con el perfeccionamiento del instrumental laparoscópico, prostatectomía radical. Presentamos nuestra experiencia inicial en prostatectomía radical laparoscópica utilizando el dispositivo Single-Incision Laparoscopic Surgery Port® de Covidien y 2 trocares auxiliares de 5mm colocados lateralmente para triangulación. El Single-Incision Laparoscopic Surgery Port® permite una inserción precisa y sencilla a través de una incisión de Hadson. El puerto flexible contiene 3 cánulas de 5mm o 2 cánulas de 5mm y una de 12mm para facilitar el intercambio de instrumental a través de la incisión única. Este abordaje disminuye la morbilidad por sangrado, hernias y/o lesión de los órganos internos y mejora los resultados cosméticos. El puerto único forma parte del desarrollo natural de la cirugía mínimamente invasiva. Se necesita más experiencia para determinar los beneficios intra y postoperatorios de la cirugía laparoendoscópica por puerto único en comparación con la laparoscopia convencional.

          Translated abstract

          Since 2007, various urological procedures have been performed with laparoendoscopic single-site surgery (LESS surgery), including nephrectomy, pyeloplasty, simple prostatectomy and, with the refinement of laparoscopic instrumentation, radical prostatectomy. This paper reports our initial experience in radical prostatectomy using the SILS TM Port from Covidiem and two lateral 5-mm trocars for triangulation. The SILS TM Port allows for accurate, simple insertion through a Hadson incision. The flexible port accomodates three 5-mm cannulas or two 5-mm cannulas and a 12-mm port for easier instrument exchange through a single incision. This approach decreases morbidity from bleeding, hernia and/or internal organ damage and improves cosmetic results. One-port single-incision laparoscopy is part of the natural development of minimally invasive surgery. Future research is required to assess the intraoperative and postoperative benefits of LESS surgery as compared to standard laparoscopy.

          Single-incision, umbilical laparoscopic versus conventional laparoscopic nephrectomy: a comparison of perioperative outcomes and short-term measures of convalescence.

          Recent reports have suggested that single-port or single-incision laparoscopic surgery (SILS) is technically feasible. To present a comparison between SILS and conventional laparoscopic nephrectomy with respect to perioperative outcomes and short-term measures of convalescence. This was a case-control study comparing 11 SILS nephrectomies (cases) and 22 conventional laparoscopic nephrectomies (controls) performed from September 2004 to April 2008. The control group was matched in a 2:1 ratio to SILS cases with respect to patient age, surgical indication, and tumor size. A single surgeon performed all SILS nephrectomy cases using three adjacent 5-mm trocars inserted through a single 2.5-cm periumbilical incision. Demographics, operative time, blood loss, perioperative complications, transfusion requirement, decrease in serum hemoglobin, analgesic requirement, length of stay, and final pathology were compared. Mean patient age was 53 yr for both groups, with more females in the SILS cohort (82% vs 41%). Nephrectomy was performed for benign disease in 45% of the cases. Median tumor size was 5.5 cm for both groups, and all but one suspected malignancy was renal cell carcinoma on final pathology. There was no difference between SILS and conventional laparoscopy cases in median operative time (122 min vs 125 min, p=0.78), percent decrease from preoperative hemoglobin (14.1% vs 15.8%, p=0.52), analgesic use (8 morphine equivalents vs 15 morphine equivalents, p=0.69), length of stay (49 h vs. 53 h, p=0.44), or complication rate (0% for both). The SILS group did have a lower recorded median estimated blood loss (20 ml vs 100ml, p=0.001). This study is retrospective and is susceptible to all limitations and biases inherent in such a design. SILS nephrectomy is feasible with perioperative outcomes and short-term measures of convalescence comparable to conventional laparoscopic nephrectomy. Although SILS may offer a subjective cosmetic advantage, prospective comparison is needed to more clearly define its role.

            Single-port laparoscopic radical prostatectomy.

            To present the initial experience in laparoscopic radical prostatectomy performed exclusively through an umbilical incision using a single three-channel port and specially designed flexible laparoscopic instrumentation. Since November 26, 2007, we have performed single-port laparoscopic radical prostatectomy in 4 patients diagnosed with prostate cancer. Patients with early-stage prostate cancer (T1c), no previous pelvic surgery, and a body mass index

              Laparoendoscopic single-site surgery in urology: where have we been and where are we heading?

              One-port, single-incision laparoscopy is part of the natural development of minimally invasive surgery. Refinement and modification of laparoscopic instrumentation has resulted in a substantial increase in the use of laparoendoscopic single-site surgery (LESS) in urology over the past 2 years. Since the initial report of single-port nephrectomy in 2007, urologists have successfully performed various procedures with LESS, including partial nephrectomy, pyeloplasty, orchiectomy, orchiopexy, ureterolithotomy, sacrocolpopexy, renal biopsy, renal cryotherapy, and adrenalectomy. Further advancements in technology, such as magnetic anchoring and guidance systems, and robotic instrumentation, may allow broader application of this emerging surgical technique. Future research is required to determine the intraoperative and postoperative benefits of LESS in comparison with standard laparoscopy.
