“…Here we focused on technical variations that exist specifically for transvaginal NOTES access, regardless of the structure to be operated on. Four distinct techniques for transvaginal NOTES cholecystectomy have been described by different centers, regarding pure natural orifice surgery or combined hybrid techniques to facilitate efficiency and safety for the procedures (Zorron et al, 2010b): -Totally NOTES dual scope method (de Sousa et al, 2009): utilizes two endoscopes inserted via the vaginal route (one single-channel gastroscope with the insufflation tube attached and one double-channel colonoscope). The former was used to retract the gallbladder and the latter to perform the cholecystectomy, thus avoiding the necessity of using transabdominal puncture for the introduction of laparoscopic forceps to expose the gallbladder (Figure 10).…”

“…The choice of endoscope and dissection tools utilized differs greatly between pure NOTES, hybrid procedures, and access routes, with wide variation even within the same procedure and access method. 16,33 Current research on developing instruments to aid performing pure NOTES is underway. 34,35 For further incorporation into humans, fundamental steps and elements present in all procedures, as well as practical and technical challenges, will need to be resolved.…”

Background Natural orifice translumenal endoscopic surgery (NOTES) is a technique that uses transvisceral access to perform surgical procedures entirely through a natural orifice. Despite the increasing awareness of NOTES, there remain obstacles to its technical feasibility and widespread acceptance. Furthermore, with the paucity of high-level supporting evidence, NOTES currently remains an experimental technique. Objective This article reviews the goals, applications, technical and practical challenges, and future direction of NOTES in gastrointestinal surgery.

Current surgical robotic systems have shown that the robotic approach bring many benefits to both surgeons and patients. However, these systems still need further improvements to increase dexterity and to facilitate a cost-effective integration in any standard operating room. With this goal, we propose a compact and accurate positioning mechanism, called Dionis. This spatial hybrid mechanism based on a parallel kinematics provides three rotations and one translation for single incision laparoscopy. The corresponding axes intersect at a remote center of motion that is coincident with the entry point into the patient's abdominal cavity. In addition, the compact design of the Dionis robot allows direct access to the patient, without removing the robotic system. This, besides saving precious space in the operating room, improves safety over existing solutions. This article presents the conceptual design of the Dionis robot followed by its workspace and dynamic analysis. The required maximum speed and maximum torque of the actuators are obtained for a set of typical trajectories to chose the most appropriate actuators. The final design and a summary of the control architecture are as well described.

Totally NOTES (T-NOTES) transvaginal cholecystectomy using two endoscopes: preliminary report

Abstract: 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.
