Abstract
BACKGROUND The objective of this study was to evaluate the novices' learning curves and proficiency level reached in laparoendoscopic single-site (LESS) surgery using three surgical training programs. MATERIAL AND METHODS Participants were randomly divided into three groups, who trained in a specific practice regimen for 12 days using a laparoscopic box simulator and three tasks. Group A trained in three stages using conventional laparoscopic surgery (CLS) with straight instruments, and LESS with straight and articulating instruments for four days each. Group B trained in two stages in LESS with straight and articulating instruments for six days each. Group C trained only in LESS with articulating instruments exclusively for all 12 days. Performance was registered daily during the 12 days to evaluate the participants' progress. RESULTS Pre- and post-training analysis of the three groups showed significant differences in performance, denoting the significant improvement in their LESS skills, with no difference between the groups. Group C reached a high level of technical competence with their specific training program in LESS, obtaining a lower asymptote and slow learning rate. CONCLUSION Specific training programs in LESS settings using articulated instruments showed a slower learning rate than the other programs but better proficiency in the technique with the best surgical performance.

Abstract
Background and Objectives: Within the past few years, there has been a push for an even more minimally invasive approach to biliary disease with the adoption of single-incision laparoscopic cholecystectomy. We sought to compare 4 individual surgeon experiences to define whether there exists a learning curve for performing single-incision laparoscopic cholecystectomy. Methods: We performed a retrospective review 290 single-incision laparoscopic cholecystectomies performed by a group of general surgeons, with varying levels of experience and training, at 3 institutions between May 2008 and September 2010. The procedure times were recorded for each single-incision laparoscopic cholecystectomy, ordered chronologically for each surgeon, and subsequently plotted on a graph. The patients were also combined into cohorts of 5 and 10 cases to further evaluate for signs of improvement in operative efficiency. Results: Of the 4 surgeons involved in the study, only 1 (surgeon 4, laparoscopic fellowship trained with <5 years' experience) confirmed the presence of a learning curve, reaching proficiency within the first 15 cases performed. The other surgeons had more variable procedure times, which did not show a distinct trend. When we evaluated the cases by cohorts of 5 cases, surgeon 4 had a significant difference between the first and last cohort. Increased body mass index resulted in a slightly longer operative time (P < .0063). The conversion rate to multiport laparoscopic surgery was 3.1%. Conclusions: Our results indicate that among experienced general surgeons, there does not seem to be a significant learning curve when transitioning from conventional laparoscopic cholecystectomy to single-incision laparoscopic cholecystectomy. The least experienced surgeon in the group, surgeon 4, appeared to reach proficiency after 15 cases. Greater than 5 years of experience in laparoscopic surgery appears to provide surgeons with a sufficient skill set to obviate the need for a single-incision laparoscopic cholecystectomy learning curve.

Abstract
OBJECTIVE Lately single-port surgery is becoming a widespread procedure, but it is more difficult than conventional laparoscopy owing to the lack of triangulation. Although, these operations are also possible with standard laparoscopic instruments, curved instruments are being developed. The aims of the study were to identify the effect of training on a box trainer in single-port setting on the quality of acquired skills, and transferred with the straight and curved instruments for the basic laparoscopic tasks, and highlight the importance of a special laparoscopic training curriculum. DESIGN A prospective study on a box trainer in single-port setting was conducted using 2 groups. Each group performed 2 tasks on the box trainer in single-port setting. Group-S used conventional straight laparoscopic instruments, and Group-C used curved laparoscopic instruments. Learning curves were obtained by daily measurements recorded in 7-day sessions. On the last day, the 2 groups changed instruments between each other. SETTING 1st Department of Surgery, Semmelweis University of Medicine from Budapest, Hungary, a university teaching hospital. PARTICIPANTS In all, 20 fifth-year medical students were randomized into 2 groups. None of them had any laparoscopic or endoscopic experience. Participation was voluntary. RESULTS Although Group-S performed all tasks significantly faster than Group-C on the first day, the difference proved to be nonsignificant on the last day. All participants achieved significantly shorter task completion time on the last day than on the first day, regardless of the instrument they used. Group-S showed improvement of 63.5%, and Group-C 69.0% improvement by the end of the session. After swapping the instruments, Group-S reached significantly higher task completion time with curved instruments, whereas Group-C showed further progression of 8.9% with straight instruments. CONCLUSIONS Training with curved instruments in a single-port setting allows for a better acquisition of skills in a shorter period. For this reason, there is a need for proficiency-based conventional, but also for a single-port, laparoscopic training curriculum in general surgery residency education.

Abstract
OBJECTIVES Laparoendoscopic single-site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES) produce excellent cosmetic outcomes, but are technically challenging. The objective of this study was to test the functionality and feasibility of a novel minimally invasive surgical paradigm, which maintains triangulation but uses special externally assembled instruments to minimize the postoperative cosmetic impact. METHODS Percutaneous Externally Assembled Laparoscopic (PEAL) instruments have specialized 2.96-mm shafts with interchangeable 5-mm working tips that are assembled externally. First, 5-mm laparoscopic, PEAL, and 2-mm needlescopic instruments were tested to determine piercing force on fresh human cadaver organs. In a bench-top study, 20 subjects assembled and used PEAL instruments in five different skills tests that were also compared with the same tasks using conventional laparoscopic instruments. Finally, PEAL instrument functionality was tested in a four-porcine nephrectomy feasibility study. RESULTS PEAL (2.80 lbF) and 5-mm laparoscopic instruments (2.28 lbF) had a significantly higher mean organ piercing perforation force compared with needlescopic instruments (1.39 lbF, p < 0.05). Average assembly time of PEAL instruments was 31.08 seconds (range: 19.83-43.85). There were no significant differences in the amount of time needed for completion of the bench-top tasks between laparoscopic and PEAL instruments (p > 0.05 for all tasks). Four-porcine PEAL nephrectomies were completed with no complications and minimal blood loss (mean 7.5 mL). Mean operative time was 98.25 minutes (range 79-116). CONCLUSION PEAL tools are easily assembled, have similar safety and efficacy compared with standard laparoscopic tools, and are less likely to injure organs compared with needlescopic instruments. They function well during laparoscopic nephrectomy and may decrease the invasiveness of conventional laparoscopic instrumentation.

Abstract
The authors found that laparoendoscopic single-site surgery with a reusable platform was feasible for various urologic entities, yielding favorable cosmetic and functional results. Background and Objectives: Many disposable platforms have been applied in laparoendoscopic single-site surgery (LESS). Besides technical issues, cost is one of the limiting factors for its widespread acceptance. The current study describes the first completely reusable LESS-platform. Methods: We performed LESS-procedures in 52 patients including nephrectomy (18), adrenalectomy (2), partial nephrectomy (3), pyeloplasty (4), renal cyst ablation (4), pelvic lymphadenectomy (15), and lymphocele ablation (6). All procedures were conducted using a novel reusable single-port device (X-Cone, Karl-Storz) with a simplified set of instruments. We obtained perioperative and demographic data, including a visual analogue pain scale (VAS), and a complication reporting system based on Clavien grading. Results: Mean age was 50.04 y. Conversion to standard laparoscopy was necessary in 3 cases and addition of a needlescopic instrument in 6 cases. There was no open conversion. Intra- and postoperative complications occurred in 3 (Clavien II in 2 and III in 1) cases. Mean operative time was 110, 90, and 89 min, and hospital stay was 4.9, 3.1, and 3.6 d for nephrectomy, pelvic lymphadenectomy, and pyeloplasty, respectively. Mean VAS was 2.13, 1.07, and 1.5 while blood loss was 81.3 mL, 25.67 mL, and 17.5 mL, respectively. Mean lymph node yield was 15 (range, 8 to 21). Conclusions: A completely reusable LESS-platform is applicable to various uses in urology, yielding favorable functional and cosmetic results. Reusable materials are useful to reduce the cost of LESS, further increasing its acceptance. LESS with a completely reusable platform is more cost effective than standard laparoscopy.

Abstract
BACKGROUND AND PURPOSE Several disposable platforms have been introduced for laparoendoscopic single-site (LESS) surgery. Besides technical issues, cost is one of the main limiting factors for their widespread use. We present our experience with LESS surgery for kidney pathologies using the first completely reusable LESS platform. PATIENTS AND METHODS We performed LESS kidney procedures in 29 patients including nephrectomy (18), partial nephrectomy (3), pyeloplasty (4), and renal cyst ablation (4). All procedures were performed using a completely reusable single-port device (X-Cone) with a simplified combination of standard and prebent instruments. We obtained perioperative and demographic data including a visual analog pain scale (VAS); complications were recorded using Clavien grading. RESULTS Mean patient age was 49.31 years. Conversion to standard laparoscopy was necessary in one and addition of a needlescopic instrument in four cases. No open conversion was necessary. Intra- and postoperative complications occurred in two (Clavien II) cases. Mean operative time was 110, 90, and 89 minutes, and hospital stay was 4.9, 3.1, and 3.6 days for nephrectomy, partial nephrectomy, and pyeloplasty, respectively. Mean VAS was 2.13, 1.67, and 1.5 while blood loss was 81.3 mL, 140 mL, and 17.5 mL, respectively. There were no positive resection margins. CONCLUSIONS LESS with a completely reusable platform is feasible for different upper urinary tract procedures yielding favorable functional and cosmetic results. A simplified combination of standard straight instruments and a single prebent grasper facilitates handling and shortens the learning curve. Reusable materials significantly reduce cost and may help to further adopt LESS surgery in surgical practice.

Abstract
INTRODUCTION Single incision laparoscopic surgery (SILS) represents the next step in laparoscopic surgery in further reducing the invasiveness of surgical procedures with cosmetic advantages. Recalling the increased rates of major complications at the advent of laparoscopic cholecystectomy 20 years ago, however, it is clear that appropriate training is required before adopting a new technique. This study aims to review the current evidence for training and skills acquisition for SILS. METHODS A comprehensive database search of PubMED, MEDLINE, EMBASE and Google Scholar was carried out. Studies considered for inclusion were those addressing SILS learning curves, skills acquisition, or training. RESULTS 21 studies were included in the final analysis. Ten clinical case series with analysis of SILS learning curve demonstrated a significant learning curve for conventional multiport laparoscopic (LAP)-trained surgeons over the course of initial SILS cases, with several studies reporting increased risk of conversion and complication rates. Five laboratory-based studies demonstrated differences in SILS skills acquisition compared with LAP. Six studies describing SILS-specific training curricula were analysed, but none included a robust validation of the curriculum. CONCLUSIONS Clinical case series and laboratory-based skills acquisition studies demonstrate the unique requirements of SILS, with skill sets and ergonomic demands which cannot be directly adapted from existing LAP experience. Some studies have already reported higher complication rates in initial SILS cases. To avoid repeating the mistakes of the past, the implementation of an evidence- and competency-based SILS curriculum is necessary to ensure appropriate training of future SILS surgeons.

Abstract
PURPOSE Many disposable platforms have been available for laparoendoscopic single-site surgery (LESS) for a long time. Besides technical challenges cost remains the limiting factor for the widespread use of LESS. We present our experiences with the first completely reusable LESS platform. METHODS We performed LESS procedures in 52 patients, including nephrectomy (n=18), adrenalectomy (2), partial nephrectomy (3), pyeloplasty (4), renal cyst ablation (4), pelvic lymphadenectomy (15) and lymphocele ablation (6). All procedures were carried out using a novel reusable single-port device (X-ConeR, Karl-Storz) with a simplified combination of standard and preformed instruments. Perioperative and demographic data including a visual analogue pain scale (VAS) were obtained. Complications were recorded using the Clavien classification. RESULTS The mean age of the patients was 50.04 years. Conversion to standard laparoscopy was necessary in 3 cases and the additional use of a 3 mm needle instrument in 6 cases. There were no open conversions. Intraoperative and postoperative complications occurred in 3 (Clavien II in 2 and III in 1) cases. Mean operating time was 110, 90, and 89 min and hospital stay was 4.9, 3.1 and 3.6 days for nephrectomy, pelvic lymphadenectomy, and pyeloplasty, respectively. The mean VAS was 2.13, 1.07 and 1.5 while blood loss was 81.3 ml, 25.67 ml and 17.5 ml, respectively. CONCLUSIONS The LESS technique with a completely reusable platform is applicable to various indications in urology yielding favorable functional and cosmetic results. This novel simplified combination of instruments facilitates handling and shortens the learning curve. Reusable materials may help to reduce cost leading to a wider acceptance of LESS.

Abstract
OBJECTIVE Single incision laparoscopic cholecystectomy (SILC) has recently emerged as an option for selected patients undergoing gallbladder removal. While SILC appears safe when performed by experienced surgeons under controlled conditions, there are no studies evaluating the SILC learning curve for incorporation into resident education and the effect on OR efficiency. DESIGN, SETTING, AND PARTICIPANTS Chief residents were taught and evaluated by a single attending surgeon facile with SILC techniques. Residents were transitioned from assistants to primary surgeon during their clinical rotation. Outcomes data were prospectively tabulated compared with data from standard laparoscopic SLC and attending surgeon SILC outcomes. The setting was an academic, tertiary care teaching hospital. Participants were chief residents rotating on hepatobiliary surgery service. Residents previously had demonstrated mastery of basic laparoscopic surgical techniques. RESULTS Seven chief residents were evaluated with a total of 49 SILCs with a mean of 7 (range 5-12) SILCS/resident. Five conversions to SLC occurred, all within the first 3 SILCs performed by the resident as operative surgeon. Mean blood loss was 30 mL. Median length of stay was <1 day. Average length of operation increased after the first 2 cases, reflecting the transition of the attending surgeon from primary surgeon to assistant role. By the fifth case, operative times returned to the attending surgeon SILC baseline and historical operative times for SLC at our institution. Factors associated with longer-length of surgery were increasing BMI and presence of acute or chronic cholecystitis, choledocholithiasis, and use of intraoperative cholangiogram. Five postoperative complications occurred and were not associated with position along the resident's learning curve. One death occurred due to metastatic laryngeal cancer within 30 days of SILC. CONCLUSIONS Residents can safely be taught the techniques of SILC with minimal disruption to operating room efficiency. Residents already proficient in the use of standard laparoscopic techniques transition to SILC quickly with a short learning curve and proper instruction.

Abstract
As essentially all operations performed with open laparotomy can be completed with minimal access, surgeons and industry continue to push the boundaries of minimally invasive surgery. New and controversial approaches, such as natural orifice translumenal endoscopic surgery (NOTES) and single incision or single port surgery are being explored with the goal of reduced surgical morbidity. The fundamental idea of single port surgery is therefore to minimize the number of abdominal wall incisions and allow access for all laparoscopic instruments through one skin incision. Several techniques in use require specialized equipment with multiple ports through one umbilical incision or one multichannel port. For single port surgery to be widely adopted surgeons must demonstrate safety, efficacy and reproducibility of the technique across a wide range of patients and clinical scenarios. In order to meet these requirements concerns about well-founded surgical training and quality monitoring must be addressed as with any major technical advance.

Abstract
Objective: This study aimed to evaluate the potential advantages of laparoendoscopic single-site surgery (LESS) approach with respect to conventional laparoscopy. Methods: Thirty LESS patients were matched 2:1 with a previous cohort of 58 patients undergoing conventional laparoscopy for the same type of surgery (controls). Results: Median operative time (38.5 vs 54 minutes; P = .09) and estimated blood loss (20 vs 30 mL; P = .008) were more favorable in patients undergoing LESS treatment compared with those undergoing conventional laparoscopy. Rupture of the cyst was observed in 11 out of 30 cases (36.6%) and 26 of 58 controls (44.8%; P = .46). Median length of stay was 1 day in the cases and 2 in the controls ( P = .03). Conclusions: Decreases in operative time, estimated blood loss, or length of stay should not be considered a benefit attributable to LESS; rather it seems there are no differences between these 2 surgical approaches after an adequate selection of patients.

Abstract
A combination of refinements in laparoscopic instrumentation and increasing surgical experience has driven innovation in the area of laparoendoscopic single-site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES). By combining working ports and the extraction incision into one site, LESS allows access to the peritoneum with fewer incisions and less scarring than the traditional multiport laparoscopic technique. Reduced incisional morbidity and improved cosmesis have sparked a growing interest in the utilization of these techniques to perform urological surgery. Mastering of the technique requires training and repetition to develop the muscle memory required to perform these challenging procedures. Although there has been an explosion of literature published about initial experiences with LESS and NOTES, little has been written about training and implementation of this approach. Here, we describe our institutional experience and the essential elements of a LESS and NOTES training curriculum and offer some insight into establishing a successful programme.

Abstract
CONTEXT Natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS) have been developed to benefit patients by enabling surgeons to perform scarless surgery. OBJECTIVE To summarize and critically analyze the available evidence on the current status and future perspectives of LESS and NOTES in urology. EVIDENCE ACQUISITION A comprehensive electronic literature search was conducted in June 2010 using the Medline database to identify all publications relating to NOTES and LESS in urology. EVIDENCE SYNTHESIS In urology, NOTES has been completed experimentally via transgastric, transvaginal, transcolonic, and transvesical routes. Initial clinical experience has shown that NOTES urologic surgery using currently available instruments is indeed possible. Nevertheless, because of the immaturity of the instrumentation, early cases have demanded high technical virtuosity. LESS can safely and effectively be performed in a variety of urologic settings. As clinical experience increases, expanding indications are expected to be documented and the efficacy of the procedure to improve. So far, the quality of evidence of all available studies remains low, mostly being small case series or case-control studies from selected centers. Thus, the only objective benefit of LESS remains the improved cosmetic outcome. Prospective, randomized studies are largely awaited to determine which LESS procedures will be established and which are unlikely to stand the test of time. Technology advances hold promise to minimize the challenging technical nature of scarless surgery. In this respect, robotics is likely to drive a major paradigm shift in the development of LESS and NOTES. CONCLUSIONS NOTES is still an investigational approach in urology. LESS has proven to be immediately applicable in the clinical field, being safe and feasible in the hands of experienced laparoscopic surgeons. Development of instrumentation and application of robotic technology are expected to define the actual role of these techniques in minimally invasive urologic surgery.
