Abstract
Surgical approach to adrenal gland has evolved from open to minimally invasive surgery. With the advent of technology, multiple techniques and approaches are available in a surgeon's armamentarium today to deal with adrenal nodules that require surgical intervention. Each approach has its own advantages and disadvantages. The era of minimal invasive surgery has fuelled our quest for better cosmesis, faster recovery, early return to work and reduced hospital stay. While minimal invasive method is the preferred approach for most benign adrenal masses less than 6 cm, its application for large adrenal lesions as well as adrenocortical carcinoma is still debatable. Single incision minimal invasive procedures further try to reduce the incisions and wound morbidity. With the aim to completely remove visible scars and possibly reduced morbidity, the concept of natural orifice transluminal endoscopic surgery (NOTES) has been proposed by some surgeons as well as interventional gastroenterologist. In NOTES, the peritoneal cavity is accessed through a hollow viscus to perform therapeutic as well as diagnostic procedures. While the theoretical advantages of scar less surgery and its advantages sound encouraging, the precise indications and its potential advantages for adrenal pathologies is yet to be defined. It should in no way, compromise our goal of safe patient surgery and outcomes.

Abstract
Transrectal access still has some unsolved issues such as spatial orientation, infection, access and site closure. This study presents a simple technique to perform transcolonic access with survival in a swine model series. A new technique for NOTES perirectal access to perform retroperitoneoscopy, peritoneoscopy, liver and lymphnode biopsies was performed in 6 pigs, using Totally NOTES technique. The specimens were extracted transanally. The flexible endoscope was inserted through a posterior transmural incision and the retrorectal space. Cultures of bacteria were documented for the retroperitoneal space and intra abdominal cavity after 14 days. Rectal site was closed using non-absorbable sutures. There was no bowel cleansing, nor preoperative fasting. The procedures were performed in 6 pigs through transcolonic natural orifice access using available endoscopic flexible instruments. All animals survived 14 days without complications, and cultures were negative. Histopathologic examination of the rectal closure site showed adequate healing of suture line and no micro abscesses. The results of feasibility and safety of experimental Transcolonic NOTES potentially brings new frontiers and future wider applications for minimally invasive surgery. The treatment of colorectal, abdominal and retroperitoneal diseases through a flexible Perirectal NOTES Access (PNA) is a promising new approach.

Abstract
BACKGROUND The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87% in the ENOTES group, which was statistically different from 78.12% in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.

Abstract
BACKGROUND: Applications for natural orifice translumenal endoscopic surgery (NOTES) to access the abdominal cavity have increased in recent years. Despite potential advantages of transanal and transcolonic NOTES for colorectal pathology, it has not been widely applied in the clinical setting. This study describes a series of nine patients for whom we performed transanal retrograde (“Down-to-Up”) total mesorectal excision for rectal cancer. MATERIALS AND METHODS: Under IRB approval, informed consent was obtained from each patient with rectal adenocarcinoma. Rectosigmoidectomy with total mesorectal excision was performed using low rectal translumenal access to the mesorectal fascia and subsequent dissection in a retrograde fashion. This was achieved using either a single port device or flexible colonoscope with endoscopic instrumentation and laparoscopic assistance. This was followed by transanal extraction of the specimen and hand-sewn anastomosis. RESULTS: Mean operative time was 311 min. Mean hospital stay was 7.56 days. Complications occurred in two patients, and consisted of one anastomotic leakage with reoperation and one intraoperative conversion to open surgery because of impossibility to dissect the specimen. TME specimen integrity was adequate in six patients. CONCLUSION: This series suggests that a retrograde mesorectal dissection via a NOTES technique is feasible in patients with rectal adenocarcinoma. This technique may act as a complimentary part of operative treatment for rectal cancer alongside other minimally invasive strategies. Long-term follow up will be needed to assess oncological results.

Abstract
Since the first animal experimental laparoscopy in 1902, minimal access techniques have revolutionized surgery. Using the natural orifice dates back to at least the second century when Soranus performed a vaginal hysterectomy. The main difference between traditional endolumenal surgery and the translumenal approach of natural-orifice translumenal endoscopic surgery (NOTES) is the intentional puncture of a healthy organ in NOTES to access a cavity or other organ. The aim of this review was to examine the past, present, and potential future role of NOTES in the context of other developments in minimal access surgery. NOTES is at an early stage in its development and a convincing benefit over laparoscopy has not been demonstrated. Concerns regarding complications, for example of viscerotomy closure, have limited the widespread uptake of pure NOTES. However, it is likely that technological advances for NOTES surgery will enhance conventional laparoscopic and endoscopic techniques.

Abstract
BACKGROUND Natural orifice transluminal endoscopic surgery procedures have evolved over the past few years. A transvaginal approach is a promising alternative for intraperitoneal procedures. Our objective was to evaluate the safety and feasibility of transvaginal organ extraction. METHODS This institutional review board-approved protocol involved retrospective review of an ongoing prospective study. Female subjects who presented to our hospital for elective cholecystectomy, appendectomy, or sleeve gastrectomy were offered participation in the study. Eligible patients met the following criteria: age between 18 and 75, diagnosis of gallbladder disease, acute appendicitis, or morbid obesity who desired surgical treatment. A hybrid transvaginal natural orifice approach was used in this series. RESULTS Thirty-four women underwent transvaginal organ extraction between September 2007 and January 2012. The mean age was 40 ± 12.1 years (range 23-63 years). The mean body mass index was 27 ± 6.4 kg/m(2) (range 16-43 kg/m(2)). All patients had an American Society of Anesthesiologists classification of two or below. The mean operative time for cholecystectomy, appendectomy, and sleeve gastrectomy was 90, 71, and 135 min, respectively. There were no conversions to open operation and no intraoperative complications. The mean hospital stay was 2 days for all cases. Patients were followed for a mean of 24 months (range 1-61 months). There were two pregnancies and two successful vaginal deliveries. Six patients (18 %) had minor complaints of spotting or heavy menses in the immediate postoperative period that resolved with conservative measures. There were no abdominal wall complications. There were no long-term complications and no mortalities. CONCLUSIONS This initial experience suggests that this surgical approach is safe, does not increase length of stay, and has no long-term vaginal complications. Given this attractive profile, a transvaginal approach may prove to be a superior mode of organ extraction, although randomized studies and long-term follow-up are needed.

Abstract
Natural orifice translumenal endoscopic surgery (NOTES) had its origins in numerous small animal studies primarily examining safety and feasibility. In human trials, safety and feasibility remain at the forefront; however, additional logistic, practical, and regulatory requirements must be addressed. The purpose of this paper is to evaluate and summarize published studies to date of NOTES in humans. The literature review was performed using PUBMED and MEDLINE databases. Articles published in human populations between 2007 and 2011 were evaluated. A review of this time period resulted in 48 studies describing procedures in 916 patients. Transcolonic and transvesicular procedures were excluded. The most common procedure was cholecystectomy (682, 75%). The most common approach was transvaginal (721, 79%). 424 procedures (46%) were pure NOTES and 491 (54%) were hybrid NOTES cases. 127 (14%) were performed in the United States of America and 789 (86%) were performed internationally. Since 2007, there has been major development in NOTES in human populations. A preponderance of published NOTES procedures were performed internationally. With further development, NOTES may make less invasive surgery available to a larger human population.

Abstract
To review natural orifice translumenal endoscopic surgery (NOTES) applications in clinical practice and assess the evidence base for each application as reported in the literature. An electronic literature search was performed. Inclusion criteria were publications relating to NOTES applications in humans. For each type of operation the highest level of evidence available for clinical NOTES publications was evaluated. Morbidity and short-term operative outcomes were compared with gold standard published evidence where available. Finally, registered trials recruiting patients for NOTES applications were identified. Human NOTES publications with the highest level of evidence in each application are identified. There were no RCTs in the literature to date. The strongest evidence came in the form of large, multi-centre trials with 300-500 patients. The results are encouraging, comparable with gold standard techniques on morbidity and mortality. While short-term operative outcomes were also similar when compared to the gold standard techniques, other than improved cosmesis little else can definitely be concluded as a clear benefit of a NOTES procedure. The most common procedures are cholecystectomy, appendicectomy and peritoneoscopy mainly performed via transvaginal access. It is evident that morbidity appears to be higher when the transgastric route is used. The safety profile of hybrid NOTES transvaginal procedures is beginning to be confirmed as is evident from the large number of procedures presented in this review. A number of authors have presented work on pure NOTES procedures but the results are inconsistent and thus the vast majority of NOTES procedures worldwide are performed in a hybrid fashion with a variable amount of laparoscopy. This review of the clinical applications of NOTES summarises the growing evidence behind this surgical discipline and highlights NOTES procedures with an acceptable safety profile.

Abstract
Minimally invasive surgery started spreading worldwide in 1987, when the first laparoscopic cholecystectomy was performed. Meanwhile, improvement of endoscopic equipment and instruments allowed gastroenterologists to attempt more aggressive endoluminal interventions, even beyond the wall barrier. The first transgastric peritoneoscopy, in 2004, brought to light the concept of natural orifice transluminal endoscopic surgery (NOTES). The idea of incisionless surgery is attractive and has become a new goal for both surgeons and other people interested in this field of investigation. The authors present a review of all developments concerning NOTES, including animal studies and human experience.

Abstract
OBJECTIVES Clinical natural orifice surgery has been applied for abdominal surgery in recent years, mostly by vaginal and oral access. The study describes preliminary successful human applications of transcolonic natural orifice transluminal endoscopic surgery (NOTES), using a new transrectal total mesorectal excision procedure for rectal cancer. METHODS Institutional review board approval was obtained for the study. In 2 patients with rectal adenocarcinoma, total mesorectal resection and rectosigmoidectomy with lymphadenectomy was performed using a low NOTES transcolonic access. "Down-to-up" mesorectal dissection was achieved either using a flexible scope or a transrectal single port device. The specimens were extracted transanally, and transorificial low anastomosis was performed. RESULTS Operative time was 350 and 360 minutes, respectively; no complications occurred and patients were discharged after 6 days. CONCLUSION Successful human reports on transcolonic NOTES suggest potential applications. The treatment of colorectal diseases through transorificial single port or flexible perirectal NOTES access are promising new approaches besides current methods to improve patient care.

Abstract
BACKGROUND Natural orifice transluminal endoscopic surgery peritoneoscopy may be able to replace laparoscopic peritoneoscopy (LAP) for staging of GI malignancies if it is proven to be equally accurate and safe. OBJECTIVE To compare transgastric peritoneoscopy (TGP) and transcolonic peritoneoscopy (TCP) to LAP, pairwise, in a randomized, blinded (to location and number of beads) human cadaver model with simulated peritoneal metastases. DESIGN Metastases were simulated by 2.5-mm, color-coded beads, which were placed into the peritoneal cavity via an open approach. In previous porcine experiments, LAP resulted in a yield of 95%. By using a noninferiority design with a margin of equivalence of 15%, we needed a sample size of 34 beads for 80% power. Randomization was performed for number and location of beads. Eighteen experiments were performed on 6 fresh-frozen human cadavers. SETTING Experimental surgical laboratory. INTERVENTION LAP, TGP, and TCP were performed in randomized order by one of two surgeons/endoscopists blinded for location and number of beads. MAIN OUTCOME MEASUREMENTS Number of beads detected and touched. RESULTS LAP found and touched 33 beads (yield 97%), TGP 26 beads (76%; difference in yield vs LAP was -20.5 [95% CI, -26.3 to -9.27]), and TCP 29 beads (85%; difference in yield vs LAP was -11.8 [95% CI, -14.6 to 4.98]). Beads that were missed were mostly located at the inferior liver surface: TGP missed 6 of 9 of these beads (67%), TCP 4 of 9 (44%). LIMITATIONS Cadaver model. CONCLUSION In this prospective, blinded, comparative trial in a human cadaver model, TCP was comparable to LAP in detecting simulated metastases. TGP was inferior to LAP. Future development should focus on improved visualization of the inferior surface of the liver.

Abstract
Tremendous advances have been made in recent years addressing the key obstacles to safe performance and introduction of human natural orifice transluminal endoscopic surgery (NOTES). Animal studies have focused on identifying optimal solutions to these obstacles, in particular methods of creating transluminal access, safe closure of the point of access, and development of a multitasking platform with dedicated instruments. Whether the performance data generated from these animal studies can be reproduced in humans has yet to be determined. Reports of human NOTES procedures are emerging, and the possibility of accomplishing human NOTES based on existing technology has been demonstrated. However, dedicated platforms and devices are still lacking to allow for pure NOTES procedures, and whether NOTES can deliver the postulated benefits of earlier recovery and improved cosmesis remains uncertain.

Abstract
OBJECTIVES Natural orifice translumenal endoscopic surgery (NOTES) is evolving as a promising alternative for abdominal surgery. IMTN Registry was designed to prospectively document early results of natural orifice surgery among a large group of clinical cases. METHODS Sixteen centers from 9 countries were approved to participate in the study, based on study protocol requirements and local institutional review board approval. Transgastric and transvaginal endoscopic natural orifice surgery was clinically applied in 362 patients. Intraoperative and postoperative parameters were prospectively documented. RESULTS Mean operative time for transvaginal cholecystectomy was 96 minutes, compared with 111 minute for transgastric cholecystectomy. A general complication rate of 8.84% was recorded (grade I-II representing 5.8%, grade III-IV representing 3.04%). No requirement for any analgesia was found in one fourth of cholecystectomy and appendectomy patients. CONCLUSIONS Results of clinical applications of NOTES in the IMTN Study showed the feasibility of different methods of this new minimally invasive alternative for laparoscopic and open surgery.

Abstract
Natural orifice transluminal endoscopic surgery (NOTES) is a new concept that attempts to reduce the impact of surgery on the patient. In surgical oncology several studies have already revealed that a minimally invasive approach provides at least the same, if not a better, long-term outcome. One could hypothesize that a less invasive approach such as NOTES could further enhance such advantages. Since its initial description, NOTES has become clinical reality and today nearly every organ is accessible by a transluminal approach, in at least the experimental setting. Subsequent to published research, first clinical studies on NOTES in oncology were reported and the accuracy of transgastric peritoneoscopy for staging of pancreas cancer was shown to be similar to laparoscopy in humans. A NOTES gastro-jejunostomy via transgastric access has also been proposed to decrease invasiveness of palliative treatment of duodenal, biliary and pancreatic cancers. Colorectal cancer resection via transanal access would offer a clear-cut patient advantage over laparoscopic and would not be subject to the frequent criticism of violating an innocent second organ, as the colon or rectum is always breached in a colectomy. Natural orifice endoluminal therapies, such as endoscopic submucosal dissection, already have been clinically applied for several years. Improved techniques or instruments evolving from NOTES technology might enhance its widespread use for the treatment of early malignancies and thereby again will provide a tremendous benefit for the patient. Although still somewhat controversial, the subject of natural orifice surgery in oncological disease indicates that current laboratory efforts to introduce NOTES into cancer surgery could be ready for cautious clinical investigations. The final determination of patient benefit will need well-constructed prospective study.

Abstract
The advent of minimally invasive surgery and the advances in endoluminal flexible endoscopy have converged to generate a new concept in digestive surgery, whose acronym natural orifice transluminal endoscopic surgery (NOTES), has become a familiar term in the surgical community. NOTES has been performed through the mouth, the bladder, the rectum and the vagina. Of these four approaches, the vagina has gained most popularity for several reasons. It is not only readily accessible and easy to decontaminate but it also provides safe entry and simple closure. The transvaginal approach has been described in the experimental and the clinical setting as an option for cholecystectomy, nephrectomy, splenectomy, segmental gastrectomy, retroperitoneal exploration and bariatric surgery. However, larger series are needed to delineate the exact risks of this approach, and to transcend cultural barriers that impede its wider introduction. Prospective randomized trials will shed light on the definitive role of the vaginal approach in minimal invasive surgery of the future.

Abstract
OBJETIVOS: Cirurgia por orifícios naturais tem sido recentemente aplicada em series clínicas para cirurgia abdominal. Apesar de potenciais vantagens do acesso NOTES transcolônico para doenças colorretais, este ainda não havia sido utilizado clinicamente. O presente trabalho descreve a primeira aplicação bem-sucedida de NOTES transcolônico da literatura, em uma nova abordagem de excisão mesoretal total (TME) para cancer de reto. MÉTODOS: Foi obtida aprovação de Comitê de Ética em Pesquisa para cirurgias por orifícios naturais, e o paciente assinou termo de consentimento informado. Em um paciente de 54 anos portador de adenocarcinoma de reto, o procedimento de retossigmoidectomia e linfadenectomia, com excisão mesoretal total foi realizada utilizando um acesso posterior transcolônico pouco acima da borda anal. A dissecção mesorretal foi conseguida utilizando um colonoscópio flexível e instrumentos endoscópicos, com assistência laparoscópica. O espécime foi retirado via transanal, e anastomose foi transorificial, com estoma proximal de proteção. RESULTADOS: O tempo operatório foi de 350 min, não ocorrendo complicações operatórias. A evolução pós-operatória foi favorável, e o paciente recebeu alta no sexto dia de pós-operatório com dieta plena. CONCLUSÃO: Este primeiro relato bem sucedido de cirurgia NOTES transcolônica traz potencialmente novas fronteiras de aplicações clínicas na cirurgia minimamente invasiva. O tratamento de doenças colorretais utilizando o novo acesso flexível PNA (Perirectal NOTES Access) é uma promissora nova abordagem, paralelamente à laparoscopia e cirurgia aberta, para melhoria do tratamento dos pacientes.

Abstract
Clinical natural orifice surgery has been applied to abdominal surgery in recent years, mostly using transvaginal and transgastric access. Rectal and transcolonic natural orifice transluminal endoscopic surgery (NOTES) were tested in animal and cadaver models by a few research groups. Despite the potential advantages of transcolonic NOTES for colorectal diseases, it has not yet been clinically applied. The first successful series of human applications of transcolonic NOTES in the literature from the NOTES Research Group in Brazil provide new possibilities in the field in new transrectal procedures for rectal cancer and benign disease. Successful first human reports on Transcolonic NOTES potentially brings new frontiers and applications for minimally invasive surgery. The treatment of colorectal diseases through flexible Perirectal NOTES Access is a promising new approach alongside existing laparoscopic and open surgery to improve patient care.

Abstract
OBJECTIVES Natural orifice translumenal endoscopic surgery (NOTES) represents the first step toward scar-less surgery. The objective of this study is to evaluate early clinical results of transvaginal cholecystectomy using a new technique. METHODS Institutional review board approval was obtained and transvaginal NOTES cholecystectomy was performed in 12 women for cholelithiasis. A 2-channel videoendoscope was inserted in the abdominal cavity through a posterior colpotomy. Two 3-mm trocars were inserted deep in the umbilicus, and a 10-mm trocar was placed through the colpotomy parallel to the endoscope. Dissection was performed with endoscopic instruments combined with 3-mm laparoscopic instruments. RESULTS Mean operative time was 125.8 minutes. All procedures occurred without intraoperative complications or conversions, except for 1 vulvar laceration. There were no postoperative complications in the clinical follow-up. CONCLUSION Transvaginal NOTES is a feasible and safe alternative for cholecystectomy in this preliminary clinical experience, allowing good cosmetic benefits and low analgesic requirement.

Abstract
A new surgical technique--called Natural Orifice Translumenal Endoscopic Surgery (NOTES)--evolved in 2004. Although numerous problems arose regarding this method--and most of them are unresolved yet--several new articles about the human application have been published. In order to find solutions of a certain extent, new techniques have been developed (hybrid NOTES, NOTUS, SPS, SLIS, etc). Although these could not eliminate difficulties completely, they do provide some solutions in many cases. It is very important for the surgeon of modern days to be familiar with these techniques and analyze them in a critically. Application of these methods requires a review of principles of surgery and flexible endoscopy. Although in many cases these are considered axioms, there data exist in literature of different management principles, as well. It is fundamental that critically review of the basic questions of NOTES (which natural orifice is the best, how to close the viscerotomy, how to avoid infection, who should carry out the NOTES surgery) is carried out in relation of the complications of the original 'gold standard' methods (e.g. frequency of infection or hernia after laparoscopy). Based on human data there is minimal postoperative pain after the NOTES procedure, and patients in general will leave the hospital on the same day. Is such a short postoperative stay enough and can we entirely dismiss drainage after cholecystectomy? Results of the human procedures are adequate to draw further conclusions regarding the new technique. Retrospective analysis of problems occurring during the evolution of laparoscopy can make it possible to avoid mistakes that can be made in the development of NOTES.

Abstract
Natural orifice translumenal endoscopic surgery (NOTES) allows access into the peritoneal cavity with a flexible endoscope, through the wall of the digestive or urogenital tracts. NOTES can be combined to laparoscopic surgery in so-called << hybrid >> techniques. In the absence of any incision of the abdominal wall, NOTES procedures provide perfect cosmetic results, with virtually no risk of parietal complications, and with decreased postoperative pain. NOTES could particularly benefit to overweight patients and to patients receiving intensive or palliative care. Most NOTES studies have been performed on animal models, with great interest for both transgastric and transpelvic approaches. Successful NOTES peritoneoscopy, hysterectomy, oophorectomy, tubal ligation, gastrojejunal anastomosis, cholecystectomy, splenectomy, nephrectomy, and abdominal-wall hernia repair have been described. In human studies, the transvaginal route is preferred. NOTES clinical research focuses on low-morbidity procedures, such as cholecystectomy, appendectomy, and peritoneoscopy. Indirect benefits are expected from this research, with possible technological innovations in the field of endoscopic instrumentation (including sutures, anastomosis, traction and triangulation). Overall, NOTES is believed to make evolve both interventional endoscopy and minimally invasive surgery.

Abstract
INTRODUCTION Natural orifice surgery has evolved from a preclinical setting into a common occurrence at the University of California San Diego (UCSD). With close to 40 transvaginal cases, we have become comfortable with this technique and are exploring other indications. One of the perceived advantages in natural orifice surgery is the potential reduction in the incidence of hernia formation. Patients with abdominal wall hernias may be at increased risk of forming additional hernias at incision sites. In addition, patients with recurrent incisional hernias may, likewise, be at increased risk. We believe that reducing or eliminating abdominal wall incisions may be of benefit in the repair of abdominal wall hernias. Here, we describe what we believe to be the first natural orifice transluminal endoscopic surgical (NOTES) approach to the repair of an abdominal wall hernia. METHODS The patient is a 38-year-old female with a painful recurrent umbilical hernia, previously repaired 8 years prior with a polypropylene-based mesh. The patient underwent a transvaginal recurrent umbilical hernia repair with one other 5-mm port in the abdomen for safety. RESULTS The patient had no intraoperative or postoperative complications. At 5 months follow up, the patient had no complaints, no evidence of hernia recurrence, and was very pleased with her result. CONCLUSIONS The repair of primary and incisional hernias of the ventral abdominal wall via a transvaginal approach is technically feasible, and the result of our initial case was exceptional. However, there are still significant obstacles which must be addressed before this approach can be widely utilized. These obstacles include safe entrance into the abdominal cavity via a transvaginal approach, the proper mesh to be placed during the repair, and the risk of infection.

Abstract
Natural orifice translumenal endoscopic surgery (N.O.T.E.S) is a technique that allows access to the peritoneal cavity through natural orifices (oral, rectal, vaginal, vesical) without passing through the anterior abdominal wall. Rapid strides have been made in developing this technique, especially in animal models. Majority of research work in this field is originating from USA, while human clinical trials are being reported from India and Southern America. Morbidly obese patients and ITU patients are two target groups where N.O.T.E.S if implemented, will have the highest potential and bearing. With increasing evidence of safe practice in human models, questions on indications and feasibility of practice need to be addressed by rigorous research, strong evidence and collaboration between surgical centers worldwide.

Abstract
BACKGROUND Clinical applications of transvaginal Natural Orifice Transluminal Endoscopic Surgery (NOTES) are still limited in the literature, mostly case reports performed by hybrid procedures with laparoscopic assistance. Avoiding complications from incisions is the main goal for natural orifice surgery. This study reports on a technique developed at our institution that uses two endoscopes inserted into the vagina to perform a Totally NOTES (T-NOTES) transvaginal cholecystectomy, and describes preliminary results. METHODS IRB approval was obtained at the institution for transvaginal NOTES clinical trials, and informed consent was obtained. The technique of T-NOTES transvaginal cholecystectomy was clinically applied in four female patients with symptomatic cholelithiasis, and data were prospectively documented. Transvaginal NOTES access was obtained by direct vaginal incision, and two endoscopes were simultaneously introduced in the abdominal cavity. Dissection was accomplished with available endoscopic instruments. Ligation of cystic duct and artery was performed using endoscopic clips. Vaginal closure was achieved using the direct-vision sutured technique. RESULTS The technique was successfully performed in the four patients. Insufflation and spatial orientation was of good quality. Mean operative time was 210 min. There were no complications during the 30-day follow-up. Postoperative course was uneventful, and patients were released from the hospital on the first postoperative day. CONCLUSION Tranvaginal T-NOTES using two endoscopes provides a feasible method for natural orifice cholecystectomy using available technology. Large-series studies are needed to evaluate the results with respect to safety of the approach.

Abstract
Gynaecological malignancies are most often diagnosed and staged by surgery. With the expanding evidence of efficacy and benefit of neoadjuvant treatments, such tumor confirmation and assessment should be ideally done with the least associated morbidity. Thus sentinel node biopsy has already been proposed for selected indications so that the morbidity associated with formal lymphadenectomy could be avoided in those patients without nodal metastases. The era of natural orifice transluminal endoscopic surgery (N.O.T.E.S.) heralds an operative methodology of 'least invasiveness' that could be useful in gynaecological cancer. In this article, we present an overview of the staging of gynaecological malignancies with a focus on the potential applications and benefits that N.O.T.E.S. may provide in this field. In particular, we believe that performing sentinel lymph node dissection with N.O.T.E.S. could associate the low morbidity rate of the former technique with the minimal invasiveness of the latter one and therefore consolidate the potential of this technique.

Abstract
The potential for performing truly scarless, safe surgery that at the same time may be less morbid is tempting both patients and physicians alike to seriously consider Natural Orifice Transluminal Endoscopy Surgery (NOTES) for a range of clinical applications. Given the move towards gastric-preservation by minimally invasive techniques for definitive management of early gastric cancer, this radical approach may find a niche within future clinical care paradigms for early stage malignant lesions of the stomach. Indeed already selected T1,N0 adenocarcinoma is being treated and even cured by advanced endoscopic techniques such as Endoscopic Submucosal Dissection. NOTES may initially therefore find a role in furthering the application of such endeavour by ensuring oncological providence in the treatment of those T1 lesions with higher risk of lymphatic metastases that currently are advised to lie outwith the scope of pure endoscopic resection (for reasons of oncological propriety rather than technical capacity). One such means NOTES could supplement ESD is by providing for direct sampling of sentinel nodes from the perigastric lymph basins. Subsequently perhaps a NOTES technique may develop capable of performing localized, full-thickness gastric wedge or sleeve resection for T2,N0 adenocarcinoma (and indeed perhaps other pathologies such as small gastrointestinal stromal tumors). This review examines how advancing technology along with progressive surgical thinking and innovation could lead to NOTES becoming absorbed into clinical care pathways for early gastric malignancy.
