Abstract
Minimally invasive adrenalectomy has become the main treatment modality for most adrenal lesions. Both laparoscopic transabdominal and retroperitoneoscopic approaches are safe and feasible options, each with respective advantages, including better surgical outcomes, fewer complications, and faster recovery over open adrenalectomy. While open surgery remains a valid modality in treatment of adrenocortical cancer in the presence of some findings such as invasion, robotic platforms, and minimally invasive surgery have gained popularity as technology continues to evolve. Organ preservation during adrenalectomy is feasible in some conditions to prevent adrenal insufficiency. Ablative technologies are increasingly utilized in benign and malignant tumors, including the adrenal gland, with various outcomes. A multidisciplinary team, an experienced surgeon, and a high-volume center are recommended for any surgical approaches and management of adrenal lesions. This review article evaluated recent findings and current evidence on minimally invasive adrenalectomy.

Laparoendoscopic single-site adrenalectomy versus multi-port laparoendoscopic adrenalectomy: A systemic review and meta-analysis. Ann Med Surg (Lond) 2021; 66:102388. [PMID: 34113440 PMCID: PMC8170104 DOI: 10.1016/j.amsu.2021.102388] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 05/03/2021] [Accepted: 05/09/2021] [Indexed: 11/22/2022] Open
Abstract
Background To investigate the outcomes of laparoendoscopic single-site adrenalectomy (LESS-A) compared to multi-port laparoendoscopic adrenalectomy (m-LA). Methods Studies comparing LESS-A with m-LA were identified from PubMed, Embase, and Cochrane Library before June 2020. Post-operative pain, resumption outcomes, and perioperative outcomes were analyzed. We conducted meta-analyses using the Mantel-Haenszel method with random-effects model. Subset analyses were conducted according to peritoneal and retroperitoneal approaches. A small study effect was illustrated using funnel plots and Egger's test. Results One randomized controlled trial (RCT) and nineteen retrospective cohort studies involving 1554 patients were included for analyzed. Pooled analysis showed that LESS-A had significantly lower postoperative pain scores (MD −0.77, 95%CI −1.45 to −0.10) and less pain medication used (RR 0.74, 95%CI 0.60 to 0.91) compared to m-LA. Besides, LESS-A had significantly shorter hospital stays (MD −0.75, 95%CI −1.18 to −0.33), shorter duration of oral intake resumption (MD −0.33, 95%CI −0.60 to −0.06), and better cosmetic satisfaction (SMD 1.15, 95%CI 0.21 to −2.09). As for perioperative outcomes, LESS-A led to significant longer operative time (MD 13.43, 95%CI 4.08 to 22.77). No significant differences were observed in terms of the remaining perioperative outcomes. Conclusions LESS-A is associated with less post-operative pain and quicker recovery duration. However, the longer operative time of LESS-A compared with m-LA is a drawback. Multi-port laparoscopic adrenalectomy (m-LA) is widely used for treatment of benign adrenal tumor. Laparoscopic single-site adrenalectomy (LESS-A) had significant less post-operative pain and less pain medication consumption comparing with m-LA. LESS-A had better resumption outcomes, including shorter hospital stay and quicker post-operative oral intake. LESS-A offer better cosmetic satisfaction. Longer operative time is a drawback of LESS-A.

Abstract
INTRODUCTION To describe laparoendoscopic single-site simple nephrectomy and reduced port simple nephrectomy for inflammatory nonfunctioning kidney. CASE PRESENTATION Case 1: a 58-year-old female with fever was referred to our hospital. Computed tomography demonstrated a markedly atrophic right kidney and mild hydronephrosis. Case 2: a 64-year-old male with a history of several intra-abdominal surgeries visited our hospital with a complaint of left back pain and fever. Computed tomography demonstrated left marked hydronephrosis, thinning of renal parenchyma, and duplicated inferior vena cava. After antibiotic treatment, transperitoneal reduced port simple nephrectomy and retroperitoneal laparoendoscopic single-site simple nephrectomy were performed in Case 1 and 2, respectively, because the function of the affected kidney was almost lost on renography. Although adhesion was slightly noted around the renal hilum in Case 1, neither conversion to laparotomy nor placement of additional ports was needed. CONCLUSION Laparoendoscopic single-site simple nephrectomy and reduced port simple nephrectomy for inflammatory nonfunctioning kidney may be options for experienced laparoscopic surgeons.

Laparoscopy allows the harvest of the DIEP flap with shorter fascial incisions as compared to endoscopic harvest: A single surgeon retrospective cohort study. J Plast Reconstr Aesthet Surg 2020; 74:1203-1212.

Abstract
BACKGROUND We present a comparative series to utilize minimally invasive endoscopic, total extraperitoneal laparoscopic (TEP-lap), and transabdominal preperitoneal robotic perforator (TAP-RAP) harvest of the deep inferior epigastric (DIE) vessels for autologous breast reconstruction (ABR) to mitigate donor site morbidity. We hypothesized that TEP-lap and TAP-RAP harvests of abdominal-based free flaps are safe techniques associated with decreased fascial incision when compared with the endoscopic harvest. METHODS We designed a retrospective cohort series of subjects with newly diagnosed breast cancer who presented for ABR using endoscopic (control), laparoscopic, or robotic assistance between September 2017 and April 2019. The primary outcome variables were flap success (i.e., absence of perioperative flap loss), fascial incision length, and intraoperative complications. Secondary variables included operating time, costs, and postoperative complications within 90 days (arterial thrombosis, venous congestion, bulge/hernia, and operative revision). Exclusion criteria included < 90 days follow-up. RESULTS In total 94, 38, and 3 subjects underwent endoscopic, TEP-lap, and TAP-RAP flap harvests. Mean lengths of fascial incisions for the endoscopic and laparoscopic cohorts were 4.5 ± 0.5 cm and 2.0 ± 0.6 cm (p < 0.0001), while incision length depended on the concurrent procedure in the robotic cohort. No subjects required conversion to an open harvest. There were no bleeding complications, intra-abdominal injuries, flap losses, or abdominal bulges/hernias noted in the TEP-lap and TAP-RAP cohorts. CONCLUSION Minimally invasive DIEP flap harvest may decrease fascial injury when compared with conventional open harvest. There are significant trade-offs among harvest methods. TEP-lap harvest may better balance the trade-off related to abdominal wall morbidity.

Abstract
BACKGROUND Minimally invasive surgery, such as laparoscopic adrenalectomy and robotic adrenalectomy, has become a treatment of choice for benign adrenal tumors. Efforts are ongoing to minimize the invasiveness of the procedure and to reduce the number of port sites. The primary endpoint of this study was the safety and feasibility of a reduced-port site technique for robotic posterior retroperitoneal adrenalectomy (RPRA). METHODS This study retrospectively analyzed 74 RPRAs performed by a single surgeon, including 30 conventional three-port site early-phase RPRAs, 30 three-port site late-phase RPRAs, and 14 reduced-port site RPRAs. Reduced-port site RRPA was defined as using two port sites: one for a multi-glove port and one for an additional side port. The clinicopathological features and surgical outcomes were compared in these three groups. RESULTS No major complications were observed following RPRA in the three groups of patients. Operation time, pain score, and hospital stay did not differ significantly among these three groups. CONCLUSIONS RPRA using a reduced-port site system was safe and feasible and may be a good alternative to conventional three-port site RPRA for benign adrenal tumors in certain situations.

Abstract
INTRODUCTION Robotic surgical technology has evolved to include a new platform specifically designed for the single-port (SP) approach. Benefits of the da Vinci SP are still under investigation. This study aimed to review the urological literature since the first report of the use of the platform. EVIDENCE ACQUISITION We performed a systematic literature review of PubMed, Medline, and Web of Science databases on June 15, 2020 searching for all available articles of da Vinci SP use from December 2014 (date of the first clinical report of da Vinci SP in the urology) until June 1, 2020 following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Guidelines. EVIDENCE SYNTHESIS A total of 43 articles were eligible for inclusion. Ten studies reported different surgeries and techniques on cadavers while the rest described the clinical experience of different groups. We divided our article and tables into preclinical experience with surgery on cadavers, radical prostatectomy (RP) approach, and multiple types of procedures described in the same study. CONCLUSIONS The application of da Vinci SP in urologic procedures after five years of the first clinical investigation is feasible and safe. Radical prostatectomy is the most common intervention performed with this robot. Some groups described benefits in terms of less postoperative pain and early discharge, especially with the extraperitoneal approach. However, further studies with larger sample sizes and longer follow-up are awaited.

Abstract
PURPOSE To describe our initial experience with laparoendoscopic radical prostatectomy (LRP) and a stepwise transition towards transurethral assisted laparoendoscopic single-site RP (TU-LESS RP). PATIENTS AND METHODS From Jan. 2007 to Dec. 2016, 195 patients underwent RP, of which 89 patients were performed by LRP (Group A), 106 by TU-LESS RP (Group B). The peri-operative data were collected and analyzed. All data referring to patient demographics, surgery, pathology, and peri-operative outcomes were recorded. The cosmetic result was investigated by the Patient Scar Assessment Questionnaire (PSAQ). Analysis of variance or Chi squared test were adopted to analyze the data. RESULTS 195 procedures were completed successfully. The operation time (109.6 ± 31.9 vs. 151.5 ± 87.3, P = 0.025) and anastomosis time (10.1 ± 4.8 vs. 21.8 ± 9.9, P < 0.001) of Group B was significantly reduced compared with Group A. Estimated blood loss in Group B was significantly lower than that in Group A (95.9 ± 11.1 vs. 180.2 ± 99.7, P = 0.006). About perioperative complications, Group B was also less compared with Group A (1.9% vs. 7.9%, P = 0.047). As to the usage of postoperative analgesics, Group B apparently used less than that in Group A (6.6% vs. 62.9%, P < 0.001), which is consistent with the visual analogue scale (VAS) of the two groups (1.7 ± 1.3 vs. 7.8 ± 1.1, P < 0.001). Patients in Group B were significantly more satisfied with incision healing than in group A (74.9 ± 9.3 vs. 49.7 ± 5.8, P < 0.001). There was no significant difference both in BCR rate and time between Group B and Group A. In urination control, more patients in Group B did not have urinary incontinence 3 month after RP compared with Group A (81.1% vs. 67.4%, P = 0.028). CONCLUSIONS LESS RP is proved to be feasible for the proper patients, but it is difficult to popularized due to inconvenient operation. While by means of TU-LESS, operating difficulty can be significantly decreased. TU-LESS RP will be wildly accepted by surgeons and patients because of cosmetic satisfaction and quicker recovery.

Reduced port laparoscopic radical nephrectomy using an umbilical zigzag skin incision for renal cell carcinoma. Int Cancer Conf J 2020; 9:212-216.

Abstract
Reduced port laparoscopic radical nephrectomy (RPLRN) is an equivalent approach to conventional laparoscopic radical nephrectomy (LRN). In LRN, one wound generally needs to be extended for specimen extraction; therefore, some ingenuity is needed to achieve a good cosmetic outcome. We herein describe our initial experience of RPLRN using an umbilical zigzag skin incision for renal cell carcinoma (RCC). A 64-year-old female [body mass index (BMI): 20.0 kg/m2] was diagnosed with right RCC, which was 35 mm in diameter (clinical T1aN0M0). Case 2: a 68-year-old male (BMI: 23.2 kg/m2) was diagnosed with right RCC, which was 58 mm in diameter (clinical T1bN0M1), and perinephric fat was relatively thick. The procedure was safely completed in both cases. Total operative times, pneumoperitoneal times, and estimated blood loss in Case 1 and 2 were 90 and 145 min, 49 and 90 min, and 5 and 80 ml, respectively, and the times required to construct umbilical ports and close umbilical wounds were 8 and 9 min and 33 and 46 min, respectively. In Case 1, the specimen was easily extracted without the extension of the umbilical skin incision, whereas it was extended by an additional 2 cm in Case 2. The umbilical wound was inconspicuous in both cases. RPLRN using an umbilical zigzag skin incision for RCC was safely performed without complications, and clashing between instruments was minimized. The high level of cosmesis is advantageous and an umbilical zigzag skin incision may contribute to more widespread use of RPLRN for RCC; however, further studies on long-term oncological outcomes are needed.

Abstract
Different groups described the single-port surgery since its first report in laparoscopic procedures. However, the acceptance of this technique among urologists, even after the robotic approach, was reduced in the past years. Therefore, to overcome the challenges related to the single-port surgery, a new robotic platform named da Vinci SP was created with exclusive single port technology. We performed a non-systematic literature review regarding the single port technique in urologic surgeries since the first laparoscopic report until the da Vinci SP robotic platform. Three different periods were described (laparoscopy, robotic, and da Vinci SP), and we focused in our experience with this new single port robot. We selected different articles and summarized the information regarding the use of single-site surgery in laparoscopic procedures and the challenges of this approach. We also reported the experience of different groups using the single port robotic technique and some recent reports of the da Vinci SP approach. In our experience with this new console, we described some critical points related to our radical prostatectomy technique and the lessons learned during the introduction of this novel platform. Previous single-site procedures described some common challenges that limited the technique expansion. However, our experience with the da Vinci SP described feasible and safe procedures with acceptable intraoperative outcomes. The introduction of this platform is recent in the market, and the literature still lacks a high level of evidence describing the long-term outcomes of this new technology.

Abstract
INTRODUCTION Although laparoendoscopic single-site adrenalectomy (LESS-A) is feasible, it is still considered as a challenging procedure because of technical limitations. Making an optimal retraction is one of major obstacles in LESS-A, and it sometimes requires additional ports or needlescopic devices. Internal organ retractor (IOR) is a novel retraction device that is applied intracorporeally without additional port. In this study, we investigated the clinical usefulness of IOR in LESS-A. MATERIALS AND METHODS Medical records of 73 consecutive patients who underwent LESS-A from March 2009 to December 2014 were reviewed. Twenty-two patients underwent LESS-A with IOR and 51 patients without IOR. RESULTS Mean age, body mass index, tumor size, operation time, estimated blood loss, and hospital stay were not significantly different between two groups. In IOR group, median number of applied IOR was 2.0 (1.0-3.0) per single operation. Mean time for application and removal was 80.0 and 46.5 seconds for a single IOR, respectively. There were no complications related to the IOR. In without IOR group, there were nine cases that needed needlescopic trocars, six cases that needed 5 mm or larger trocars, and one case that was converted to hand-assisted laparoscopy. However, we did not use any needlescopic instrument or additional trocar in IOR group. There was no case of open conversion in both groups. CONCLUSION LESS-A could be done effectively and safely using IOR. IOR system maintained optimal retraction throughout the operation. Its application and removal are intuitive and take only a few minutes. We think IOR system is an attractive retraction method in LESS-A.

Abstract
Laparoendoscopic single-site (LESS) approach has been successfully employed for a number of urologic procedures. The retroperitoneal approach further limits the working space and instrument movement during LESS surgery, but has the advantage of a faster post-operative recovery and lower complications rate. We present our first experience using retroperitoneal LESS approach for a renal cyst decortication in a 40-year-old patient. The operative time was 40 minutes, the blood loss was minimal and we did not encounter significant conflicts between the instruments. The patient was discharged 2 days after the procedure and returned to full normal activity within one week. We consider that the retroperitoneal LESS approach is feasible for upper tract urologic surgery. Pre-bent instruments might further improve surgical gestures and extend the indications for more complex procedures. Nevertheless, the advent of reusable devices is expected to increase the cost-effectiveness of LESS and expand its use.

Abstract
INTRODUCTION Laparoendoscopic single-site surgery is a recently innovated urologic surgical procedure. Transumbilical laparoendoscopic single-site adrenalectomy (LESS-A) is technically safe and feasible in patients with benign adrenal tumors. To improve patient counseling and informed consent, we evaluated patient-reported postoperative pain, body image, and cosmetic satisfaction after transumbilical LESS-A. METHODS We reviewed 24 patients who underwent transumbilical LESS-A and assessed their operative and esthetic outcomes and incisional pain. Incisional pain was evaluated using a 10-point visual analog scale, and the body image and cosmetic satisfaction were measured using a questionnaire that included a body image scale (range, 5-20 points) and a cosmetic scale (range, 3-24 points). RESULTS Pure LESS-A was performed on 10 patients using a multichannel port; an additional 5-mm trocar was used in two obese patients. Supplementary to the single-incision approach, one or two 3-mm ports were used in 12 patients. The mean operative time was 203 min; the mean blood loss was 41 mL. The mean pain visual analog scale scores on postoperative days 1, 3, and 7 were 3.5, 2.2 (P = 0.012), and 1.5 points (P = 0.018), respectively. The mean body image scale and cosmetic scale scores indicating wound satisfaction 1 month after the surgery were 20 and 22 points, respectively. Although one patient had liver injury during surgery, the postoperative course during the 3-month follow-up was uneventful. CONCLUSION Transumbilical LESS-A confers less postoperative pain and better cosmetic satisfaction than conventional laparoscopic adrenalectomy. Therefore, this procedure could potentially become a standard treatment option for benign adrenal tumors.

Abstract
Robotic-assisted laparoscopic surgery in urology is an ever progressing field, and boundaries are constantly broken with the aid of new technology. Advancements in instrumentation have given birth to the era of robotic laparoendoscopic single-site technique (R-LESS). R-LESS however, has not gained widespread acceptance due to technical hurdles such as adequate triangulation, robotic arm clashing, decreased access for the bedside assistant, lack of wrist articulation, continued need for an axillary/accessory port, lack of robust retraction, and ergonomic discomfort. Many innovations have been explored to counter such limitations. We aim to give a brief overview of a history and development of R-LESS urologic surgery and outline the latest advancements in the realm of urologic R-LESS. By searching PubMed selectively for relevant articles, we concluded a literature review. We searched using the keywords: robotic laparoscopic single incision, robotic laparoendoscopic single-site, single incision robotic surgery, and R-LESS. We selected all relevant articles in that pertained to single-site robotic surgery in urology. We selected all relevant articles that pertained to single-site robotic surgery in urology in a table encompassed within this article. The development of the R-LESS procedures, instrumentations, and platforms has been an evolution in progress. Our results showed the history and evolution toward a purpose-built single-port robotic platform that addresses previous limitations to R-LESS. Even though previous studies have shown feasibility with R-LESS, the future of R-LESS depends on the availability of purpose-built robotic platforms. The larger concern is the demonstration of the definitive advantage of single-site over the conventional multiport surgery.

Abstract
OBJECTIVE To report on a multi-institutional series of non-robotic urological laparoendoscopic single-site surgery in Japan. METHODS Consecutive cases of laparoendoscopic single-site surgery carried out between February 2009 and December 2012 at nine academic institutions were included. We examined the surgical outcomes, including conversion and complications rates. RESULTS Four hundred and sixty-nine cases were included in the analysis. The most common procedure was adrenalectomy (n = 177) and the second most common procedure was radical nephrectomy (n = 143). The procedures also included nephroureterectomy (n = 40), living donor nephrectomy (n = 40), pyeloplasty (n = 30), urachal remnant excision (n = 9), simple nephrectomy (n = 7), radical prostatectomy (n = 6) and others (n = 17). The access sites included umbilicus (n = 248, 53%) and other sites (n = 221, 47%). A transperitoneal approach was used in 385 cases (82%), and retroperitoneal approach in 84 cases (18%). The median operation time of all procedures was 198 min. Conversion to reduced port surgery, conventional laparoscopy, or open surgery was noted in 27 cases (5.8%), 12 cases (2.6%), and two cases (0.4%), respectively, with an overall conversion rate of 8.7%. Intraoperative complications occurred in 10 cases (2.1%). Post-operative complications were noted in 29 cases (6.2%), including five major complications (1.1%). No mortality was recorded in this series. CONCLUSIONS Non-robotic laparoendoscopic single-site surgery is technically feasible and safe for various urologic diseases in Japan. Furthermore, urological laparoendoscopic single-site surgery is a promising minimally invasive surgical option that is feasible for experienced urological surgeons in intermediate-volume centers as well as high-volume centers.

Abstract
BACKGROUND Recently, laparoendoscopic single-site adrenalectomy (LESS-A) has been developed as an alternative treatment for adrenal tumors. Although LESS-A is more technically complex than conventional laparoscopic adrenalectomy, its learning curve and the factors associated with poor surgical outcomes are poorly understood. We analyzed the learning curve of LESS-A and attempted to identify risk factors associated with worse surgical outcomes. METHODS We identified 103 patients who underwent LESS-A [performed by the same surgeon (A.M.)] from 2009 to 2015. The learning curve was analyzed using the moving average method (the 10-case moving average), and we assessed potential risk factors for a prolonged pneumoperitoneum time. RESULTS The learning curve stabilized at 30 cases. The cases were divided into two groups, the learning stage (LS) (cases 1-29) and master stage (MS) (cases 30-103) groups. The percentage of females and the frequency of previous abdominal surgery were higher in the LS group (p = 0.022 and 0.001, respectively). In the LS group, the mean pneumoperitoneum time was 92 ± 35 min, which was significantly longer than the equivalent value for the MS group (55 ± 18 min, p < 0.001). In the LS group, univariate analysis revealed that tumor size (≥50 mm) and the visceral fat area (VFA)/total fat area (TFA) ratio (≥0.49) were significantly associated with a prolonged pneumoperitoneum time (p = 0.046 and 0.046, respectively). In the multivariate analysis, tumor size and the VFA/TFA ratio were confirmed to be associated with a prolonged pneumoperitoneum time (p = 0.029 and 0.029, odds ratio 20.83 and 20.83, respectively). On the other hand, none of the examined factors were found to be associated with a prolonged pneumoperitoneum time in the MS group. CONCLUSIONS LESS-A was performed safely in most cases. However, surgeons who are learning the LESS-A procedure need to pay attention to tumor size and visceral obesity.

Abstract
INTRODUCTION Over the last 2 decades, open surgery has been largely displaced by laparoscopic surgery for the treatment of renal masses. Recently, minimally invasive surgical techniques, such as laparoendoscopic single-site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES), have been developed for such purpose. METHODS In the present literature review, the current status of treatment for small renal masses was investigated. The advantages and disadvantages of LESS and NOTES are presented to confirm the feasibility and reproducibility of these techniques. RESULTS LESS significantly reduces pain and offers excellent cosmetic outcomes with comparable oncological and perioperative results, and NOTES offers the potential for surgery by various approach without any transcutaneous abdominal incision in management of small renal masses. CONCLUSION When the technical limitations are overcome, clinical application of LESS and NOTES is expected to increase. Further prospective and comparative studies are needed to clarify the application of these new techniques.

Abstract
BACKGROUND The quest for less traumatic abdominal approaches is changing paradigms in times of minimally invasive surgery. While natural orifice translumenal endoscopic surgery remains experimental, the single-incision approach could be the future of gallbladder surgery. METHODS Prospectively collected data from 875 patients subjected to conventional single-incision laparoscopic cholecystectomy (SILC) or 4-port [laparoscopic cholecystectomy (LC)] were retrospectively analyzed and discussed with the current literature. RESULTS Between 2008 and 2011, 201 (23%) SILCs and 674 (77%) LCs were performed. Mean age was 51.7±17.5 years (SILC: 45.1 vs. LC: 53.7 y). Patients were predominantly female (SILC: 75.1% vs. LC: 56.5%). Preoperative body mass index was 27.4±9.1 (SILC: 26.4 vs. LC: 27.8; P<0.05) and American Society of Anesthesiologists' score counted 1.67±0.57 in SILC and 1.86±0.7 in LC patients. Acute inflammation of the gallbladder (AIG) was not considered as a contraindication for SILC (AIG in SILC: 17.4% vs. LC: 35.5%). The mean operative time was significantly lower in the SILC group (SILC: 71±31 vs. LC: 79±27 min) and duration of postoperative hospital stay was shorter (SILC: 3.2±1.7 vs. LC: 4.5±2.6 d). No significant difference was observed between SILC and LC in any of the registered complications, including postoperative bleeding, trocar hernias, wound infection, abdominal abscess formation, bile duct injury, or cystic duct leakage. CONCLUSIONS In the near future SILC could overrule conventional LC as the leading technique for gallbladder surgery. Our data reconfirm an excellent risk profile for SILC that is equal to that of LC. Large multicenter randomized controlled trials will be required to finally legitimize SILC as the succeeding principal method.

Abstract
Introduction and Objectives: It has been established that robotic-assisted laparoscopic surgery has several advantages when compared with standard laparoscopic surgery. Optics, ergonomics, dexterity and precision are all enhanced with the use of a robotic platform. For these reasons, it was postulated that the application of robotics to laparoendoscopic single-site surgery (LESS) could overcome some of the constraints seen with the conventional laparoscopic approach. Issues such as instrument clashing, inability to achieve effective triangulation for dissection and difficulties with intracorporeal suturing have limited the widespread adoption of conventional LESS. The application of robotics has eliminated many of the constraints experienced with conventional LESS; however, challenges still remain. Materials and Methods: A systematic literature review was performed using PubMed to identify relevant studies. There were no time restrictions applied to the search, but only studies in English were included. We used the following search terms: Robotic single site surgery, robotic single port surgery, robotic single incision surgery and robotic laparoendoscopic single site surgery. Results: A number of centers have published their experience with robotic-laparoendoscopic single-site surgery (R-LESS); however, no prospective studies exist. What is clear is that R-LESS minimizes several of the difficulties experienced with conventional LESS, including intracorporeal suturing and triangulation during dissection. Outcomes are comparable to standard robotic surgery, with a trend toward improved cosmesis and reduced pain. However, a significant advantage with regard to these two factors has yet to be demonstrated. Conclusions: R-LESS is technically feasible and the benefits of robotic surgery eliminate many of the challenges seen with conventional LESS. However, despite the advantages of the robotic platform, R-LESS is not free of challenges. Instrument clashing remains an issue due to the bulky profile of the current robotic system. Other issues include lack of space for the assistant at the bedside, inability to incorporate the 4th robotic arm for retraction and difficulties with triangulation. Although solutions for some of these issues are currently under development, R-LESS is still very much in its infancy.

Abstract
BACKGROUND Laparoendoscopic single site (LESS) surgery may have perceived benefits of reduced visible scarring compared to conventional laparoscopic (LAP) totally extraperitoneal (TEP) hernia repairs. We reviewed the literature to compare LESS TEP inguinal hernia repairs with LAP TEP repairs. METHODS We searched electronic databases for research published between January 2008 and January 2012. RESULTS A total of 13 studies reported on 325 patients. The duration of surgery was 40-98 minutes for unilateral hernia and 41-121 minutes for bilateral repairs. Three studies involving 287 patients compared LESS TEP (n = 128) with LAP TEP (n = 159). There were no significant differences in operative duration for unilateral hernias (p = 0.63) or bilateral repairs (p = 0.29), and there were no significant differences in hospital stay (p > 0.99), intraoperative complications (p = 0.82) or early recurrence rates (p = 0.82). There was a trend toward earlier return to activity in the LESS TEP group (p = 0.07). CONCLUSION Laparoendoscopic single site surgery TEP hernia repair is a relatively new technique and appears to be safe and effective. Advantages, such as less visible scarring, mean patients may opt for LESS TEP over LAP TEP. Further studies with clear definitions of outcome measures and robust follow-up to assess patient satisfaction, return to normal daily activities and recurrence are needed to strengthen the evidence.

PURPOSE To evaluate the Single-Incision Transumbilical Surgery (SITUS) technique as compared to an established laparoendoscopic single-site surgery (LESS) technique (Single-Port Laparoscopic Surgery, SPLS) and conventional laparoscopy (CLS) in a surgical simulator model. METHODS Sixty-three medical students without previous laparoscopic experience were randomly assigned to one of the three groups (SITUS, SPLS and CLS). Subjects were asked to perform five standardized tasks of increasing difficulty adopted from the Fundamentals of Laparoscopic Surgery curriculum. Statistical evaluation included task completion times and accuracy. RESULTS Overall performances of all tasks (except precision cutting) were significantly faster and of higher accuracy in the CLS and SITUS groups than in the SPLS group (p = 0.004 to p < 0.001). CLS and SITUS groups alone showed no significant difference in performance times and accuracy measurements for all tasks (p = 0.048 to p = 0.989). CONCLUSIONS SITUS proved to be a simple, but highly effective technique to overcome restrictions of SPLS. In a surgical simulator model, novices were able to achieve task performances comparable to CLS and did significantly better than using a port-assisted LESS technique such as SPLS. The demonstrated advantages of SITUS may be attributed to a preservation of the basic principles of conventional laparoscopy, such as the use of straight instruments and an adequate degree of triangulation.

Abstract
Single-port laparoscopic surgery (SPLS) is implemented through a tailored minimal single incision through which a number of laparoscopic instruments access. Introduction of operation-customized port system, utilization of a camera without a separate external light, and instruments with different lengths has brought the favorable environment for SPLS. However, performing SPLS still creates several hardships compared to multiport laparoscopic surgery; a single-port system inevitably leads to clashing of surgical instruments due to crowding. To overcome such difficulties, investigators has developed novel concepts and maneuvers, including the concept of inverse triangulation and the maneuvers of pivoting, spreading out dissection, hanging suture, and transluminal traction. The final destination of SPLS is expected to be a completely seamless operation, maximizing the minimal invasiveness. Specimen extraction through the umbilicus can undermine cosmesis by inducing a larger incision. Therefore, hybrid laparoscopic technique, which combined laparoscopic surgical technique with natural orifice specimen extraction - i.e., transvaginal or transanal route-, has been developed. SPLS and NOSE seemed to be the best combination in pursuit of minimal invasiveness. In the near future, robotic SPLS with natural orifice transluminal endoscopic surgery’s way of specimen extraction seems to be pursued. It is expected to provide a completely or nearly complete seamless operation regardless of location of the lesion in the abdomen.

Abstract
CONTEXT This is a short version of the European Association of Urology (EAU) guidelines on robotic and single-site surgery in urology, as created in 2013 by the EAU Guidelines Office Panel on Urological Technologies. OBJECTIVE To evaluate current evidence regarding robotic and single-site surgery in urology and to provide clinical recommendations. EVIDENCE ACQUISITION A comprehensive online systematic search of the literature according to Cochrane recommendations was performed in July 2012, identifying data from 1990 to 2012 regarding robotic and single-site surgery in urology. EVIDENCE SYNTHESIS There is a lack of high-quality data on both robotic and single-site surgery for most upper and lower urinary tract operations. Mature evidence including midterm follow-up data exists only for robot-assisted radical prostatectomy. In the absence of high-quality data, the guidelines panel's recommendations were based mostly on the review of low-level evidence and expert opinions. CONCLUSIONS Robot-assisted urologic surgery is an emerging and safe technology for most urologic operations. Further documentation including long-term oncologic and functional outcomes is deemed necessary before definite conclusions can be drawn regarding the superiority or not of robotic assistance compared with the conventional laparoscopic and open approaches. Laparoendoscopic single-site surgery is a novel laparoscopic technique providing a potentially superior cosmetic outcome over conventional laparoscopy. Nevertheless, further advantages offered by this technology are still under discussion and not yet proven. Due to the technically demanding character of the single-site approach, only experienced laparoscopic surgeons should attempt this technique in clinical settings. PATIENT SUMMARY This work represents the shortened version of the 2013 European Association of Urology guidelines on robotic and single-site surgery. The authors systematically evaluated published evidence in these fields and concluded that robotic assisted surgery is possible and safe for most urologic operations. Whilst laparoendoscopic single-site surgery is performed using the fewest incisions, the balance between risk and benefit is currently unclear. The evidence to support the conclusions in this guideline was generally poor, but best for robotic assisted radical prostatectomy. As such, these recommendations were based upon expert opinion, and further high-quality research is needed in this field.

Abstract
Laparoscopic surgery was developed at the end of the 1980s and has been utilized in almost all urologic surgical procedures. It offers the benefits of less invasiveness and earlier recovery than open surgery. The introduction of laparoendoscopic single-site surgery has offered reduced pain and improved cosmetic satisfaction to patients. Scarless nephrectomy has been realized with transvaginal natural orifice transluminal endoscopic surgery in women. The development of surgical robots has decreased the technical difficulty of complicated procedures, shortened the learning curve, and improved perioperative outcomes relative to laparoscopic surgery. Surgical navigation using real-time sonography, augmented reality, fluorescence, or radioisotope images will improve the quality of these surgeries.

Abstract
PURPOSE To assess the efficacy and safety of laparoendoscopic single-site adrenalectomy (LESS-A) and conventional laparoscopic adrenalectomy (LA) as a systematic review and meta-analysis of current evidence. METHODS We conducted a thorough search for comparative studies that compared LESS-A and conventional LA in the following databases: MEDLINE, EMBASE, and the Cochrane library. Studies were reviewed independently and rated by Newcastle-Ottawa Quality Assessment Scale. The operative time, estimated blood loss in operation, the time to resume oral intake after surgery, postoperative hospital stay, and the visual analog pain scale (VAPS) score were included for analysis to compare the efficacy, while the complications together with the analgesia use were included for analysis to compare the safety. RESULTS Nine studies with 171 LESS-A cases and 272 conventional LA cases were identified. Although operative time was longer in LESS-A (mean difference [MD] 15.46, 95% confidence interval [CI] 11.18 to 19.74), estimated blood loss (MD 4.72, 95% CI 12.08 to 21.52) and the time to resume oral intake (MD -0.04, 95% CI -0.19 to 0.11) were similar; LESS-A presented a shorter postoperative stay in hospital (MD -0.60, 95% CI -0.86 to -0.35) and lower VAPS score (MD -1.21, 95% CI -1.44 to -0.97). Besides, the risk of minor postoperative complications (risk ratio [RR] 1.74, 95% CI 0.78 to 3.87) was similar. The postoperative analgesia demand in total (RR 0.65, 95% CI 0.52 to 0.81) together with the analgesia usage lasting more than 24 hours after surgery (RR 0.35, 95% CI 0.21 to 0.58) were associated with lower risk in LESS-A, however. CONCLUSIONS Based on current evidence, the operative time seems to be longer in LESS-A; however, operative blood loss and complications are similar. In addition, LESS-A presents a shorter hospital stay after surgery and more acceptable perception of pain than conventional LA.

Robot-assisted posterior retroperitoneoscopic adrenalectomy using single-port access: technical feasibility and preliminary results. Ann Surg Oncol 2013; 20:2741-5.

Abstract
BACKGROUND Posterior retroperitoneoscopic adrenalectomy (PRA) has several benefits compared with transperitoneal adrenalectomy in that it is safe and has a short learning curve. In addition, it provides direct short access to the target organ, prevents irritation to the intraperitoneal space, and does not require retraction of adjacent organs.1 (-) 3 We have performed several cases of robot-assisted PRA using single-port access for small adrenal tumors. This multimedia article introduces the detailed methods and preliminary results of this procedure. METHODS Five patients underwent single-port robot-assisted PRA between March 2010 and June 2011 at our institution. During the procedure, patients were placed in a prone jackknife position with their hip joints bent at a right angle (Fig. 1). A 3 cm transverse skin incision was made just below the lowest tip of the 12th rib (Fig. 2), and the Glove port (Nelis, Kyung-gi, Korea) was placed through the skin incision while maintaining pneumoretroperitoneum (Fig. 3). CO2 was then insufflated to a pressure of 18 mm Hg to create an adequate working space. A 10 mm robotic camera with a 30-degree up view was placed at the center of the incision through the most cephalic portion of the Glove port. A Maryland dissector or Prograsp forceps (Intuitive Surgical, Inc., Sunnyvale, CA) was placed on the medial side of the incision, and Harmonic curved shears (Intuitive Surgical) were placed on the lateral side of the incision (Fig. 4). Using the Maryland dissector and the harmonic curved shears, the Gerota fascia is opened, perinephric fat is dissected, and the kidney upper pole is mobilized to expose the adrenal gland (Fig. 5). Gland dissection starts with lower margin detachment from the upper kidney pole in a lateral to medial direction (Fig. 6). After dissecting the adrenal gland from surrounding adipose tissue and medial isolation of the adrenal central vein, the vessel is ligated with a 5 mm hemolock clip (Fig. 7). Patient clinicopathologic data were analyzed retrospectively. RESULTS The mean patient age was 56.6 ± 8.7 (range, 47-69) years. Right and left side approaches were used in two and three patients, respectively. All cases were adrenal cortical adenoma. The mean tumor size was 1.48 ± 0.28 (range, 1.0-1.7) cm. The mean surgery duration (skin to skin) was 159.4 ± 57.6 (range, 103-245) minutes, and the mean estimated blood loss was 46.0 ± 56.8 (range, 5-120) ml. The average time to oral intake and postoperative hospital stay were 0.65 ± 0.11 (range, 0.54-0.79) days and 4.0 ± 2.23 (range, 3-8) days, respectively. There were no conversions to open surgery or postoperative compli- cations. DISCUSSION Some trials of minimally invasive single-access surgery of the adrenal gland have recently been performed.4 (,) 5 However, these new techniques have several limitations as a result of restrictions on instrumentation movement because of the small access ports used and relatively low-quality images produced. The recent introduction of the da Vinci S surgical robot system (Intuitive Surgical) to endoscopic surgery has improved instrumental dexterity and provided the surgeon with an ergonomically designed operating system. This system is also potentially safer and more meticulous in performing operations than endoscopic procedures as a result of a 3-D, magnified, stable operative view.6 (,) 7 The advantages of the da Vinci S surgical robot system and the numerous benefits of the posterior retroperitoneal approach motivated us to utilize single-port robot-assisted PRA. The primary selection criteria were small tumor size and a minimal amount of periadrenal fatty tissue because robot-assisted PRA using single-port access provides a small operative space, which causes manipulation problems when tumors are large. To ensure the safe application of these new techniques, we recommend that novice surgeons begin using single-port robot-assisted PRA for smaller tumors < 2 cm in patients with a body mass index of < 30 kg/m(2), gradually extending the size and body mass index as they accumulate experience. Although robot-assisted PRA using single-port access could not be compared with the other robotic adrenalectomy techniques in this study, the potential advantages of this approach compared to conventional robot-assisted transperitoneal adrenalectomy include a reduction in postoperative ileus, bacterial contamination, and intestinal complications because the peritoneal cavity is not opened, in addition to a reduction in postoperative pain because of its minimally invasive nature. CONCLUSIONS Our initial experiences with robot-assisted PRA using single-port access assured us of its safety and feasibility for the resection of small adrenal tumors. Although single-port robot-assisted PRA appears to be safe and feasible, further experience and research is required to optimize patient selection criteria and verify its advantages over the traditional three-incision PRA technique.

Abstract
INTRODUCTION Laparoscopic adrenalectomy is the technique of choice in the treatment of adrenal tumors. SILS has recently been introduced in this field and applied in Viet Duc University Hospital. Herein, we report our experience with single-incision transperitoneal adrenalectomy. METHODS Between August 2010 and January 2012, 61 patients (23 men, 38 women) underwent SILS adrenalectomy at our institution. The diagnoses consisted of 20 patients with pheochromocytoma, 17 with nonfunctioning adenoma, 16 with Conn syndrome, 4 with Cushing syndrome and 4 with adrenal cysts. The mean age was 47.8 years (range, 21-68 years). There were 29 right-sided and 32 left-sided tumors; their mean diameter was 30.7 mm (range, 8-59 mm). Patients were in the flank position with the operated side up. A 2.5-cm pararectal incision at the level of the umbilicus was made to insert the SILS Port. RESULTS The mean operating time was 78 min (range, 50-120 min), and mean blood loss was approximately 70 mL. Left-sided tumors were excised entirely with the SILS technique. Right-sided lesions sometimes required an additional trocar (hybrid technique). No drainage was needed at the operating site. There were no intraoperative or postoperative complications, but one case was converted to the conventional three-port technique. The mean length of hospital stay was 3.4 days (range, 2-6 days). CONCLUSION Our preliminary results show that SILS adrenalectomy is safe and technically feasible. It should be considered among the surgical managements for selected patients with adrenal tumors.

Abstract
OBJECTIVE To retrospectively review our initial experience with respect to evaluating the feasibility and safety of retroperitoneal laparoendoscopic single-site surgery (LESS) for renal cyst decortication using the single trocar technique. PATIENTS AND METHODS Between April 2010 and November 2011, 45 patients with symptomatic simple renal cyst have undergone retroperitoneal LESS using the single trocar technique by the same experienced laparoscopic surgeon. A 10-mm 0° laparoscope with a 6-mm working channel and straight conventional laparoscopic instruments were used during all the procedures. Salient demographic and operative data were recorded, including age, body mass index, operative time, estimated blood loss, perioperative complications, analgesic requirement, etc. RESULTS Forty-three cases were accomplished successfully. In the remaining 2 patients dense adhesions around the renal cyst were encountered, and the operations were completed with an additional 5-mm trocar. The mean operative time was 49 minutes. The mean estimated blood loss was 12 mL. The mean in-hospital analgesic requirement was 2.8 mg of morphine equivalent. The mean time for ambulation postoperatively was 2 days; at the same time the drainage catheter was removed. The mean hospital stay was 3 days. There were no major perioperative complications, but superficial wound infection was noted in 1 patient. CONCLUSIONS Our initial experience with retroperitoneal LESS by the single trocar technique shows the safety and feasibility for renal cyst decortication and provides acceptable operative outcomes.

Abstract
BACKGROUND Laparoscopic adrenalectomy via three or four trocars is a well-established procedure. This report describes the initial experience with single-incision laparoscopic surgery (SILS) using the transperitoneal approach for left adrenalectomy. METHODS Between April 2010 and August 2011, all consecutive patients with adrenal masses, including Conn's syndrome, Cushing's adenoma, and nonfunctional adrenal tumors, who agreed to undergo SILS adrenalectomy were included in a prospective study. The left 2.5-cm subcostal incision was the sole point of entry. Data of patients who underwent SILS adrenalectomy were compared with those from an uncontrolled group of patients who underwent conventional laparoscopic adrenalectomy during the same study period. RESULTS There were 20 patients in each study group (20 men, 20 women; mean age [SD] = 50 [6.5] years). SILS was successfully performed and none of the patients required conversion to an open procedure. In one case of SILS procedure, an additional lateral 5-mm port was needed for retraction of the kidney. The mean (SD) duration of the operation was 95 (20) min in the SILS group and 80 (8) min in the conventional laparoscopic adrenalectomy group (p = 0.052). There were no intraoperative or postoperative complications. There were no differences between the two study groups with respect to postoperative pain, number of patients who resumed oral intake within the first 24 h, final pathologic diagnosis, and length of hospital stay. CONCLUSION SILS left adrenalectomy is a technically feasible and safe procedure in carefully selected patients. The definitive clinical, aesthetic and functional advantages of this technique require further analysis.

Abstract
OBJECTIVE We aimed to investigate the use of single-port laparoscopy in a series of patients undergoing Burch colposuspension with an extraperitoneal approach as an alternative treatment for scarless surgery in stress urinary incontinence. MATERIAL AND METHODS From September 2010 to May 2011 we performed single-port extraperitoneal laparoscopic Burch colposuspension for stress incontinence in 15 patients. Fifteen women who were diagnosed with urodynamic stress incontinence were included in the study. Demographic and clinical data, intraoperative findings, and postoperative course were recorded. RESULTS The mean age was 45,80 ± 9,91 years (range: 38-70 years). The mean body mass index was 25,67 ± 4.06 kg/m2 (range: 22.23-35.38 kg/m(2)). The mean operation time and mean blood loss were 40.80 ± 5.94 minutes (range: 30-50 minutes) and 30.67 ± 11.00 cc (range: 10-50 cc), respectively. The single-port laparoscopic operations were technically completed successfully without placement of additional trocars and there were no complications. The cure and improvement rates following laparoscopic Burch colposuspension via single port were 73.3 % and 20 % respectively. CONCLUSION Single-port laparoscopic Burch can be an alternative treatment for scarless surgery in stress incontinence. Single-incision laparoscopic Burch colposuspension can offer suitable, effective and safe treatment in women with stress incontinence.

Abstract
OBJECTIVES To describe the onset of a single port laparoendoscopic program to carry out oncology surgery in a Urology Service. We present the initial experience in the laboratory and in the Animal Facility with rigid precurved instruments and KeyPort reusable access element (Richard Wolf). MATERIAL AND METHODS Two surgeons experienced in laparoscopic surgery and with the help of four assistants performed a training program based on predetermined tasks performed in simulation boxes (pelvitrainer) and porcine model following the requirements of the Regional Community of Madrid to handle experimental animals. RESULTS The participants in this program were initially divided into pairs made up of an experienced surgery and assistant for the predetermined multiple tasks in simulator box in order to become familiarized with the instruments. After, 20 animal sessions were conducted in which the following were performed: (retroperitoneal or pelvic) lymph node dissections (n = 20), nephrectomies (n = 40), cystorrhaphy with suture (n = 20) and uterine-vesical anastomosis (n = 20). Times needed to perform the exercises and the principal errors perceived during the performance of each one of the tasks were recorded. The tasks, of growing complexity, were performed with the instruments described in increasingly less time and with less difficulty. An accessory trocar of 3.5 mm was required to perform the in vivo sutures. CONCLUSIONS The KeyPort approach has potential application in different urological applications. Standardized training allows the acquirement of skills and makes the successful implementation possible of a laparoendoscopic surgery program in humans.

Abstract
OBJECTIVE To assess the feasibility, safety, and efficacy of transperitoneal laparoendoscopic single-site (LESS) adrenalectomy and determine whether it shows any objective advantage compared with standard laparoscopy. METHODS From August 2009 to May 2011, 13 transperitoneal LESS adrenalectomies were performed through a 2-3-cm skin incision using the TriPort access system. This cohort was compared with a contemporary 1:2 matched-pair group of 26 patients undergoing standard laparoscopic adrenalectomy by the same urologist. The perioperative outcomes, including cosmetic satisfaction scores, were statistically analyzed. RESULTS The 2 groups were comparable with respect to patient demographics, estimated blood loss, and postoperative hospitalization (P > .05). The LESS procedures had a longer mean operative time (148.5 vs 112.9 minutes, P = .032) but a significantly lower postoperative visual analog pain scale score (2.3 vs 3.7, P = .001), fewer patients requiring analgesics (30.8% vs 73.1%, P = .011), and an earlier resumption of oral intake (21.6 vs 26.0 hours, P = .002). The mean length of the scar in the LESS group was much smaller (2.3 vs 5.9 cm, P < .0001) with a statistically significant greater mean cosmetic satisfaction score (9.5 vs 9.1, P = .042). CONCLUSION The perioperative outcomes of transperitoneal LESS adrenalectomy for small adrenal tumors were comparable to those with the standard laparoscopic approach. It also provides better postoperative pain control, faster recovery of bowel function, and better cosmetic satisfaction than standard laparoscopy, albeit with a longer operative time.

Abstract
INTRODUCTION To assess the feasibility of single-incision laparoscopic surgery (SILS) in some urological surgeries. MATERIAL AND METHODS This prospective study was conducted on 40 patients (27 males and 13 females) from January 2010 to June 2011. Six procedures were done, SILS renal cyst decortication (n = 10), SILS varicocelectomy (n = 10), SILS orchiopexy (n = 10), SILS nephrectomy (n = 3), SILS pyelolithtomy (n = 6) and SILS adrenalectomy (n = 1). RESULTS Postoperative complications included ileus (10%) and fever (10%) in SILS renal cyst ablation. SILS varicocelectomy had postoperative sequalae as persistent varicocele (10%) and hydrocele (10%). SILS orchiopexy was also done with a success rate 100% in this series. SILS pyelolithotomy was successfully done in 5 out of 6 patients and only 1 patient was converted to conventional laparoscopy. In SILS nephrectomy 1 patient out of 3 was converted to conventional laparoscopy. CONCLUSION SILS in urology has proven to be safe and feasible in the hands of experienced laparoscopic surgeons, using specially designed ports and instruments in selected patients.

Abstract
BACKGROUND Laparoscopy is the most common procedure for correction of congenital pyloric stenosis. The standard laparoscopic approach is based on the three-port technique. In contrast to the standard laparoscopic technique, the single-incision laparoscopic surgery (SILS) requires only one incision. We report on our experience with this surgical approach. MATERIALS AND METHODS Between September 2009 and August 2010 a total of 24 children underwent a laparoscopic pyloromyotomy, 12 in SILS technique. The single incision was carried through the center of the umbilicus. The working instruments were introduced in a two-dimensional direction into the peritoneal cavity via the same umbilical incision. The two groups were compared for patients' demographics, operative report and early postoperative outcomes. RESULTS All SILS procedures were performed successfully with no conversion rate. There were no differences in the preoperative parameters between the two groups regarding age before surgery and body weight at operation. Operative time and time of full enteral intake was similar to comparable procedures with usage of a standard laparoscopic approach. There were no operative or postoperative complications. CONCLUSIONS The early experience described in this study confirms that SILS can be applied for treatment of pyloric stenosis with outcomes similar to the standard laparoscopic surgery.

Abstract
BACKGROUND Sub-total colectomy and restorative proctocolectomy with j-pouch ileo-anorectal anastomosis is the treatment of choice in children with ulcerative colitis uncontrolled with medical therapy. OBJECTIVE To present some technical considerations about children undergoing laparoscopic ileal-J-pouch anorectal anastomosis. SETTINGS AND PATIENTS All patients with ulcerative colitis undergoing laparoscopic ileal-J-pouch anorectal anastomosis were evaluated from January 2006 to February 2011. INTERVENTION The new technical innovations herein are (1) total laparoscopic approach, (2) a very short 3-cm J-pouch ileal reservoir created outside the stoma incision, (3) preservation of the entire anal canal and the Knight-Griffen double stapled anastomosis, less than 3 cm from the dentate line, (4) use of a Multiple Instrument Access Port system in the stoma skin incision to reduce the number of port site incisions and (5) proctectomy performed using only an electrosurgical vessels sealing device thus avoiding clips to close rectal pedicle. RESULTS Seventeen laparoscopic ileo J-pouch low rectal anastomosis were performed by the same surgical staff. Three complications occurred postoperatively: one bowel obstruction, one ileostomy prolapse, and one anastomotic stricture. Satisfactory functional results were achieved in all, there was no significant perineal excoriation and quality of life was excellent. CONCLUSIONS A Multiport Instrument Access Port placed in the stoma site allowed the use of more instruments through a single incision. The very short ileo J-pouch low rectal anastomosis has been shown to be a safe, feasible, and effective reconstructive procedure.

Abstract
Today, endoscopic adrenalectomy has become a gold standard in endocrine surgery. To minimize the morbidity and improve cosmesis, single access retroperitoneoscopic adrenalectomy (SARA) has been developed as an alternative to traditional multiport laparoscopy and single port access (SPA) surgery, potentially exploiting even more the already proven benefits of minimally invasive surgery. We applied the SARA technique to adrenalectomy using the posterior retroperitoneal approach. The aim is to highlight the current situation regarding the feasibility and safety of single access retroperitoneoscopic adrenalectomy and to present our initial experience. Between October 2010 and February 2011, a 74-year-old woman (body mass index (BMI) - 31 kg/m(2)) with pheochromocytoma (1.2 cm in size) and 3 women, aged 45, 46 and 66 years (BMI - 27, 32, 33 kg/m(2)), respectively, and all diagnosed with Conn's adenoma (from 1.2 cm to 2.0 cm in size), underwent single access retroperitoneoscopic adrenalectomies. Operations were performed using conventional laparoscopic (STORZ) equipment. No conversions to the open or conventional retroperitoneal approach were necessary. There were no perioperative or postoperative complications. Operating time ranged from 60 min to 80 min. All patients left the hospital 2 days after surgery. The single access retroperitoneoscopic technique has been successfully applied to adrenalectomy as an available alternative to multiport laparoendoscopic adrenalectomy and single port access surgery. Exposure, visualization and dissection are the same as in retroperitoneal endoscopic adrenalectomy. The SARA surgery offers patient benefits such as faster convalescence, decreased postoperative scarring, better cosmetic effect and financial benefit.

Abstract
A standard procedure for single-port laparoscopic adrenal surgery has not been established. We retrospectively investigated intraoperative and postoperative outcomes after laparoscopic adrenalectomy through mono port (LAMP) and conventional laparoscopic adrenalectomy to assess the feasibility of LAMP. Between March 2008 and December 2009, 22 patients underwent adrenalectomy at the Department of Surgery, Kangbuk Samsung Hospital. Twelve patients underwent conventional laparoscopic adrenalectomy and 10 patients underwent LAMP. The same surgeon performed all the surgeries. The 2 procedures were compared in terms of tumor size, operating time, time to resumption of a soft diet, length of hospital day, and postoperative complications. The 2 groups were similar in terms of tumor size (30.08 vs. 32.50 mm, P=0.796), mean operating time (112.9 vs. 127 min, P=0.316), time to resumption of a soft diet (1.25 vs. 1.30 d, P=0.805), and length of hospital day (4.08 vs. 4.50 d, P=0.447). Despite 1 patient in the LAMP group experiencing ipsilateral pleural effusion as a postoperative complication, this parameter was similar for the 2 groups (P=0.195). Perioperative mortality, blood transfusion, and conversion to open surgery did not occur. Perioperative outcomes for LAMP were similar to those for conventional laparoscopic adrenalectomy. LAMP appears to be a feasible option for adrenalectomy.

Abstract
Since the first laparoscopic adrenalectomy, the technique has evolved and it has become the standard of care for many adrenal diseases, including pheochromocytoma. Two laparoscopic accesses to the adrenal have been developed: transperitoneal and retroperitoneal. Retroperitoneoscopic adrenalectomy may be recommended for the treatment of pheochromocytoma with the same peri-operative outcomes of the transperitoneal approach because it allows direct access to the adrenal glands without increasing the operative risks. Although technically more demanding than the transperitoneal approach, retroperitoneoscopy can shorten the mean operative time, which is critical for cases with pheochromocytoma where minimizing the potential for intra-operative hemodynamic changes is essential. Blood loss and the convalescence time can be also shortened by this approach. There is no absolute indication for either the transperitoneal or retroperitoneal approach; however, the latter procedure may be the best option for patients who have undergone previous abdominal surgery and obese patients. Also, retroperitoneoscopic adrenalectomy is a good alternative for treating cases with inherited pheochromocytomas, such as multiple endocrine neoplasia type 2A, in which the pheochromocytoma is highly prevalent and frequently occurs bilaterally.

Abstract
LaparoEndoscopic Single-Site (LESS) surgery has been developed as an extension of conventional laparoscopy to provide a minimally invasive option with fewer incisions, minimizing scars and potentially improving postoperative convalescence. These techniques have been adopted in the practice of urologic surgery, and largely employed to date for upper tract surgery by urologists in specialized centers with advanced laparoscopic practices. Herein, we review the current experience with upper tract urologic LESS surgery.
