“…Consequently, in recent years, numerous devices have been developed to stitch, staple, or clip GI wall defects from an endoluminal approach. 1,4,6,8,[12][13][14][15][16][17][18][19][20] One of these novel devices is the OTSC system, which has recently become commercially available in Europe and is in the regulatory process in the United States. The system consists of a nitinol alloy clip that is preloaded on a transparent 10-, 12-, or 14-mm applicator cap mounted on the endoscope tip (Video 1, available online at www.giejournal.org).…”

“…The simple application of current endoclips enables only a single-layer mucosal approximation. Using two endoscopes to provide layer-by-layer endoscopic clip closure is another alternative that uses current endoscopic instruments (2). An original technique, using a modified cardiac septal occluder, has demonstrated a zero leak rate (3) and was widely used for survival studies on animal models (Figure 1).…”

The aims of the ANUBIS™ project developed in IRCAD-Strasbourg were to evaluate the concept and the potentialities of natural orifices transluminal endoscopic surgery (NOTES), to develop a specific instrumentation, to translate the research work into clinical settings and to provide education and training. To achieve these goals, an intensive collaboration was established between IRCAD, which comprises medical staff (surgeons, gastroenterologists, gynaecologists), computer scientists and robotics engineers, and industrial partners. Between 2005 and 2008, more than 400 experimental procedures were performed on inanimate models, ex-vivo tissues, animal models and human cadavers. Cholecystectomy was defined as the procedure that would realize the translation of experimental work into the clinical setting. The first human transvaginal cholecystectomy was performed at the end of the second year of the project. Transgastric cholecystectomy followed six months later. A new concept of therapeutic flexible endoscope (Anubiscope™, Storz Endoskope,Tutlingen, Germany) was developed, and different modalities of closure of the viscerotomies were elaborated. Implementation of the experimental program into the clinical setting and translation of technological research into a finalized industrial product were achieved thanks to a rigorous, extensive and stepwise study of the potentialities of NOTES. Education and training were organized and 500 participants attended the specific courses and hands-on sessions organized at IRCAD-EITS.

Once in a few decades in science or medicine, an idea emerges that is so powerful that it changes forever how we think about that field. Natural Orifices Translumenal Endoscopic Surgery (NOTES) has the potential to break the physical barrier between bodily trauma and surgery. At the dawn of surgery, excellence was associated with big incisions: “big scar ‐ big surgeon”. In the 80s, minimally invasive surgery was born representing one of the greatest surgical evolutions of the 20th century. After Kalloo's first report in 2004 on transgastric peritoneoscopy in a porcine model, the interest in natural orifice transluminal endoscopic surgery (NOTES) has blossomed. Theoretically the same operation performed laparoscopically could be carried out through natural orifices without any abdominal incision avoiding pain and scarring. The lesson learned from the advent of laparoscopic surgery, thought us that we could be witnessing the birth of another surgical revolution. Since 2004 many abdominal procedures that use a NOTES approach have been successfully performed in animal models. However, the initial excitement for NOTES has been somewhat tempered by the reality that a NOTES procedure in human without laparoscopic assistance has not been performed by most groups. Indeed, a major issue is the lack of stable operative platform and flexible instruments that allow retraction and exposure of the organs, such as appendix or gallbladder. Will this issue change the future of NOTES?

Peroral Dual Scope for Natural Orifice Transluminal Endoscopic Surgery (NOTES) Gastrotomy Closure

Abstract: This transoral dual-scope clipping method of gastrotomy closure after NOTES, as well as the general concept of employing 2 separate instruments at the same time perorally, is proven technically feasible, safe, and effective in this model.
