- Contemporary urologic minilaparoscopy: indications, techniques, and surgical outcomes in a multi-institutional European cohort.Publication . Porpiglia, F; Autorino, R; Cicione, A; Pagliarulo, V; Falsaperla, M; Volpe, A; Gozen, AS; Celia, A; De Sio, M; Saita, A; Damiano, R; Zacchero, M; Fiori, C; Terrone, C; Bertolo, R; Greco, F; Breda, A; Lima, E; Rassweiler, JOBJECTIVES: To provide an analytical overview of contemporary indications, techniques, and outcomes of urologic minilaparoscopy (ML) in multiple European centers. METHODS: Data of patients who had undergone a minilaparoscopic urologic procedure at nine European institutions between 2009 and 2012 were retrospectively gathered. Surgical procedures were classified as upper or lower urinary tract and as ablative or extirpative and reconstructive. The main surgical outcome parameters were analyzed and relevant operative data related to the surgical technique were recorded. RESULTS: Overall, 192 patients (mean age 45.25±17.8 years) were included in the analysis. Most of them were nonobese (mean body mass index [BMI] 24.7±3.6 kg/m(2)) at low estimated surgical risk (mean American Society of Anesthesiologists [ASA] 1.69±0.68). Indications for surgery were mostly nononcologic (132 cases, 68.8%). Most of the procedures were done in the upper urinary tract (133 cases, 69.2%) and were mostly with a reconstructive intent (109 cases, 56.7%). Overall operative time was 132.7±52.3 minutes with an estimated blood loss of 60.9±47.6 mL while the mean hospital stay was 5±2.1 days. Most of the postoperative complications were low Clavien grade (1 and 2), with only one (0.5%) grade 3 and one (0.5%) grade 4 complications recorded. CONCLUSIONS: A broad range of common procedures can be safely and effectively performed with ML techniques. By duplicating the principles of standard laparoscopy, but potentially offering less surgical scar and trauma, ML can be regarded as a viable option when looking for a virtually "scarless" surgery.
- Current status and future perspectives in laparoendoscopic single-site and natural orifice transluminal endoscopic urological surgery.Publication . Autorino, R; Stein, RJ; Lima, E; Damiano, R; Khanna, R; Haber, GP; White, MA; Kaouk, JHObjective of this study is to provide an evidence-based analysis of the current status and future perspectives of scarless urological surgery. A PubMed search has been performed for all relevant urological literature regarding natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS). In addition, experience with LESS and NOTES at our own institution has been considered. All clinical and investigative reports for LESS and NOTES procedures in the urological literature have been considered. A wide variety of clinical procedures in urology have been successfully completed by using LESS techniques. Thus far, experience with NOTES has largely been investigational, although early clinical reports are emerging. Further development of instrumentation and platforms is necessary for both techniques to become more widely adopted throughout the urological community.
- Experimental foundation for natural orifice transluminal endoscopic surgery and hybrid natural orifice transluminal endoscopic surgeryPublication . Lima, E; Rolanda, C; Autorino, R; Correia-Pinto, JNatural orifice transluminal endoscopic surgery (NOTES) is one of the most exciting concepts that has emerged recently in the surgical field. All accesses to the abdominal cavity in the porcine model using natural orifices, e.g. transgastric, transvesical, transcolonic and transvaginal, have been described and explored. The experimental feasibility of all procedures by NOTES was successfully demonstrated in the porcine model using different types of natural orifices. However, few translations to the human have been made. NOTES is in a developmental stage and much work is still needed to refine techniques, verify safety and document efficacy. This paper is an update on the experimental foundation for NOTES and hybrid NOTES and examines the opportunities presented by this new surgical vision.
- Laparoendoscopic single-site and natural orifice transluminal endoscopic surgery in urology: a critical analysis of the literaturePublication . Autorino, R; Cadeddu, JA; Desai, MM; Gettman, M; Gill, IS; Kavoussi, LR; Lima, E; Montorsi, F; Richstone, L; Stolzenburg, JU; Kaouk, JHCONTEXT: 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.
- Low-cost reusable instrumentation for laparoendoscopic single-site nephrectomy: assessment in a porcine modelPublication . Autorino, R; Kim, FJ; Rane, A; De Sio, M; Stein, RJ; Micali, S; Correia-Pinto, J; Kaouk, JH; Lima, EPURPOSE: To test different sets of prebent instruments and a new reusable access device for laparoendoscopic single-site (LESS) surgery. MATERIALS AND METHODS: Three surgeons with previous experience in LESS performed 12 nephrectomies in six pigs. In all procedures, a multichannel access device (X-CONE) and a 5-mm extra-long telescope were used. Four sets of prebent instruments with different profiles (S-portal) were tested: Standard (one straight scissors and one curved grasper), Cuschieri, Carus, and Leroy set (each of them consisting of two curved instruments with different configurations). Assessment was performed based on both objective (procedure time; time to manage the pedicle; time to free kidney) and subjective parameters (entry/exit of instruments; triangulation; dissection up/down; dissection lateral; retraction; interdependence). The subjective assessment tool used was a Likert type scale (1 = easy to 5 = prohibitive). The access device was assessed by using objective (time to complete insertion of device after skin incision) and subjective (significant air leakage, movement constraint) parameters. RESULTS: Time to insertion of the X-CONE was <1 minute in all the cases. Surgeons reported significant insufflant leakage in 58% of cases. The procedure was completed in 10/12 (83%) cases. Mean operative time was 8.3 ± 4.2 minutes, being lower for the Carus group (4.5 min) and higher for the standard group (13 min). Among the different sets, the standard one obtained the best mean scores for all subjective parameters. CONCLUSIONS: X-CONE allows easy abdominal access, and its reusable properties represent cost savings for LESS compared with disposable devices. Prebent instruments might also represent attractive low-cost tools for LESS.
- Mini-laparoscopy, laparoendoscopic single-site surgery and natural orifice transluminal endoscopic surgery-assisted laparoscopy: novice surgeons' performance and perception in a porcine nephrectomy modelPublication . Autorino, R; Kim, FJ; Rassweiler, J; Sio, M; Ribal, MJ; Liatsikos, E; Damiano, R; Cindolo, L; Bove, P; Schips, L; Rané, A; Quattrone, C; Correia-Pinto, J; Lima, E
- Natural orifice transluminal endoscopic surgery (NOTES): where are we going? A bibliometric assessment.Publication . Autorino, R; Yakoubi, R; White, WM; Gettman, M; De Sio, M; Quattrone, C; Di Palma, C; Izzo, A; Correia-Pinto, J; Kaouk, JH; Lima, EThe aim of this study was to analyse natural orifice transluminal endoscopic surgery (NOTES)-related publications over the last 5 years. A systematic literature search was done to retrieve publications related to NOTES from 2006 to 2011. The following variables were recorded: year of publication; article type; study design; setting; Journal Citation Reports® journal category; authors area of surgical speciality; geographic area of origin; surgical procedure; NOTES technique; NOTES access route; number of clinical cases. A time-trend analysis was performed by comparing early (2006-2008) and late (2009-2011) study periods. Overall, 644 publications were included in the analysis and most papers were found in general surgery journals (50.9%). Studies were most frequently clinical series (43.9%) and animal experimental (48%), with the articles focusing primarily on cholecystectomy, access creation and closure, and peritoneoscopy. Pure NOTES techniques were performed in most of the published reports (85%) with the remaining cases being hybrid NOTES (7.4%) and NOTES-assisted procedures (6.1%). The access routes included transgastric (52.5%), transcolonic (12.3%), transvesical (12.5%), transvaginal (10.5%), and combined (12.3%). From the early to the late period, there was a significant increase in the number of randomised controlled trials (5.6% vs 7.2%) or non-randomised but comparative studies (5.6% vs 22.9%) (P < 0.001) and there was also a significant increase in the number of colorectal procedures and nephrectomies (P = 0.002). Pure NOTES remained the most studied approach over the years but with increased investigation in the field of NOTES-assisted techniques (P = 0.001). There was also a significant increase in the adoption of transvesical access (7% vs 15.6%) (P = 0.007). NOTES is in a developmental stage and much work is still needed to refine techniques, verify safety and document efficacy. Since the first description of the concept of NOTES, >2000 clinical cases, irrespective of specialty, have been reported. NOTES remains a field of intense clinical and experimental research in various surgical specialities
- Novel method of full-thickness bladder closure with an endoscopic suturing machine: a survival study in a porcine modelPublication . Oliveira, C; Autorino, R; Ferreira, C; Cicione, A; Damiano, R; De Sio, M; Correia-Pinto, J; Lima, EOBJECTIVE: To assess the feasibility of a pure endoscopic closure method for vesical perforations using fully absorbable material. MATERIALS AND METHODS: A pilot experimental study was performed in eight anaesthetized female pigs. Four 10-mm and four 20-mm endoscopic full thickness cystotomies were created. An endoscopic suturing machine (RD-180®; LSI Solutions, Victor, NY, USA) was deployed through the working channel of a cystoscope and used to close the incisions with absorbable sutures. Immediate assessment of the quality of the closure was obtained by distending the bladder with saline solution stained with methylene blue under laparoscopic control. After 3 weeks of follow-up, a necropsy examination was performed to check for signs of peritonitis and wound dehiscence and to assess the quality of healing. RESULTS: The experiment was completed in all eight pigs without complications. The median procedure time was 10 ± 4.3 min. The immediate bladder distention test did not show any methylene blue leakage. The postoperative period was uneventful. The post mortem examination after 3 weeks revealed complete healing of the bladder wall incisions with no signs of infection, wound dehiscence or adhesions in the peritoneal cavity of any of the pigs. CONCLUSION: This study describes a successful novel method for endoscopic closure of bladder perforations. The technique was easy, reproducible and safe. Nevertheless, further experimental investigation should be carried out before clinical application of this method.
- Public perception of "scarless" surgery: a critical analysis of the literaturePublication . Autorino, R; White, WM; Gettman, MT; Khalifeh, A; De Sio, M; Lima, E; Kaouk, JHEvidence relating to the perception and view of patients and physicians on natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS) was scrutinized. A comprehensive literature search was performed through PubMed. A total of 18 studies were included in the analysis. Patients demonstrated interest in scarless surgery, with a preference for LESS over NOTES. Safety and efficacy remain the key factors in the decision-making process of patients. With more information about the safety and reproducibility of LESS and NOTES, and with improved educational efforts, patients and physicians alike may feel more comfortable in widespread application of scarless surgery.
