Abstract
The flexible endoscope is playing an increasingly pivotal role in minimally invasive transluminal and endoluminal surgery. Whilst the flexible nature of the platform is desirable in order to navigate through the abdominal cavity or through a lumen, there are a number of issues with using the platform for this purpose.
The challenges associated with using flexible endoscopes such as a lack of triangulation of instruments and force transmission, which is often inadequate for endoscopic surgery are discussed in this review.
As a result of these difficulties, a number of mechanically and robotically driven devices based upon the flexible endoscope are emerging. The design of these devices and potential problems are also reviewed. Finally, future robotic systems which are still in the development and validation stage are briefly discussed.
The field of gastroenterology is diverging. The narrowing divide between minimally invasive and endoluminal surgery has led to a surge of innovative and novel devices which may in the future enable precise, seamless and scar less surgery.

<abstract><p>The flexible endoscope is playing an increasingly pivotal role in minimally invasive transluminal and endoluminal surgery. Whilst the flexible nature of the platform is desirable in order to navigate through the abdominal cavity or through a lumen, there are a number of issues with using the platform for this purpose.</p>
<p>The challenges associated with using flexible endoscopes such as a lack of triangulation of instruments and force transmission, which is often inadequate for endoscopic surgery are discussed in this review.</p>
<p>As a result of these difficulties, a number of mechanically and robotically driven devices based upon the flexible endoscope are emerging. The design of these devices and potential problems are also reviewed. Finally, future robotic systems which are still in the development and validation stage are briefly discussed.</p>
<p>The field of gastroenterology is diverging. The narrowing divide between minimally invasive and endoluminal surgery has led to a surge of innovative and novel devices which may in the future enable precise, seamless and scar less surgery.

<body><sec sec-type="intro"><title>Introduction</title>
<p>The evolution of the flexible endoscope is transforming both gastroenterology and surgery. Since Bozzini first used candlelight to examine “canals and cavities of the human body” <xref rid="JR010-1" ref-type="bibr">1</xref>
, the endoscope has undergone repeated improvements. Modifications to the basic design in the 1960 s improved the image quality, although few changes have occurred since.</p>
<p>Laparoscopic surgery marked the dawn of minimally invasive surgery, prompting the advent of other techniques, such as natural orifice transluminal endoscopic surgery (NOTES) and endoluminal surgery (ELS). This new surgical philosophy places an emphasis on minimizing trauma with smaller or no incisions, thereby resulting in less soft tissue damage. Other benefits include improved cosmesis, faster recovery times, fewer complications, and less postoperative pain. This paradigm shift has placed the flexible endoscope at the forefront of a range of clinical scenarios.</p>
<p>Despite considerable evolutions in the field of surgery, the basic design of the flexible endoscope has changed little since its initial development. However, this is likely to change with the growing popularity of ELS and the goal to integrate NOTES into clinical practice. The device has been modified over the years, becoming slimmer, offering variable degrees of stiffness and advanced imaging, and revolutionizing the field of gastroenterology. Nonetheless, barriers to NOTES, such as reliable and safe internal wound closure, access to the peritoneal cavity, visualization, and spatial orientation, remain and hinder its wider uptake <xref rid="JR010-2" ref-type="bibr">2</xref>
. NOSCAR (Natural Orifice Surgery Consortium for Assessment and Research), the working group of the American Society of Gastrointestinal Endoscopy (ASGE)/Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), published its white paper in 2006 <xref rid="JR010-3" ref-type="bibr">3</xref>
, leading to a number of emerging platforms for NOTES and ELS. </p>
<p>Limitations of and improvements to all devices have been described, and as yet there is no clear superior platform. While flexible platforms allow navigation and surgery in tight workspaces, they often fail to achieve the desired forces at the distal tip effectors for adequate tissue handling and dissection <xref rid="JR010-2" ref-type="bibr">2</xref>
. In addition, there is often a lack of stability and dexterity, inadequate positioning of the scope, and a lack of triangulation of instruments down the working channel of a scope with a narrowed diameter (<xref rid="TB010-1" ref-type="table">Table 1</xref>
). </p>

<p>An exciting endeavor in the development of a workable NOTES and ELS platform is robotics. This field has undergone a revolution since the introduction of robots such as the Da Vinci, with a drive to miniaturize robots and operate in an intraluminal workspace. </p>
<p>A number of robots are in development or are being used for a wide range of roles ranging from aviation and aerospace to security and nuclear technology, yet design iterations for a robotic minimally invasive surgical platform remain. Robots like the Flex System (Medrobotics, Raynham, MA, USA) and the highly articulated robotic probe (HARP) have been designed for surgery in difficult-to-reach anatomic areas, such as the oropharynx and heart. The Endotics system (Era Endoscopy, Peccioli, Italy) <xref rid="JR010-4" ref-type="bibr">4</xref>
and the soft colonoscopy robotic platform developed by engineers at Vanderbilt University in Nashville, Tennessee, United States, are exciting new prospects for robotic colonoscopy <xref rid="JR010-5" ref-type="bibr">5</xref>
<xref rid="JR010-6" ref-type="bibr">6</xref>
in which semi-automatic inchworm motion and magnetic coupling, respectively, are used. Emerging robots from Intuitive Surgical (Sunnyvale, CA, USA) and Titan Medical Inc. (Toronto, ON, Canada) with highly dextrous micro-instruments may also be potential future platforms for endoluminal and transluminal surgery.</p>
<p>The flexible endoscopic platform plays a key role in NOTES and ELS; however, challenges remain. This review focuses on emerging flexible platforms that are being developed for NOTES and ELS. Although these devices are not yet commercially available, they incorporate changes to the long-standing basic design of the endoscope that provide a more versatile platform for ELS.</p>
</sec>
<sec><title>Nonrobotic endoscopic platforms</title>
<p>Endoscopic platforms for NOTES and ELS are largely adapted from the flexible endoscope (<xref rid="TB010-2" ref-type="table">Table 2</xref>
, <xref rid="FI010-1a" ref-type="fig">Fig. 1</xref>
). Although this allows a flexible platform to operate in a restricted workspace, optimal visualization of the mucosa and tissue manipulation remain problematic. </p>

<sec><title>Dual-channel endoscope (Olympus, Hamburg, Germany)</title>
<p>The dual-channel endoscope was developed to improve bimanual coordination and tissue manipulation compared with a conventional endoscope. The endoscope consists of a control section with two stacked control dials, a flexible shaft, and a connector segment. The connector segment attaches to water, a light source, an image processor, and air or carbon dioxide for insufflation. It requires one operator to use the device, although an assistant is often needed to operate the instruments. </p>
<p>The device has a 120° field of view with four-way angulation and a flexible shaft that is 12.6 mm in diameter housing a 3.7-mm channel for suctioning and a 2.8-mm working channel. This enables the use of two interchangeable instruments, including focused energy devices, to be deployed simultaneously. Early NOTES procedures and hybrid NOTES/laparoscopic procedures were performed with this device <xref rid="JR010-7" ref-type="bibr">7</xref>
<xref rid="JR010-8" ref-type="bibr">8</xref>
. </p>
<p>Bimanual coordination for adequate tissue manipulation and dissection is almost impossible; a hybrid approach improves the ability to retract tissue. This is in part due to the fact the working channels are placed parallel and adjacent to the camera. The camera is at the distal tip of the scope, so that the instrument must be retracted to provide a view of the operative field. Insufflation of the peritoneal cavity also requires a supplemental force, and often large-volume suction capabilities are inadequate.</p>
</sec>
<sec><title>EndoSamurai (Olympus)</title>
<p>The EndoSamurai is a multitasking flexible endoscopic platform developed for NOTES procedures. It is an endoscopic shaft with two independent manipulator arms containing working channels through which flexible instruments can be interchangeably operated. The arms remain parallel to the shaft during insertion and can be opened out into the working position, giving the appearance of elbows. This stance allows five degrees of freedom and better triangulation of instruments than is achievable with a dual-channel endoscope. A third working channel is also included in the shaft, although its position does not allow adequate triangulation of instruments and hence provides suboptimal countertraction of tissue. </p>
<p>The platform uses a traditional endoscopic steering unit with conventional endoscopic features, such as suction, lens rinsing, and air insufflation. An overtube allows stable positioning of the device once it is locked into place. The arms can then be manipulated with an ergonomic interface comprising laparoscope-like handles in a “drive, park, and move” fashion. Although the overtube improves stability of the platform, it requires repeated adjustments, thus increasing procedural time. </p>
<p>Overall, this is an improved platform for NOTES and endoluminal surgery that allows better triangulation of instruments, stability, and manipulation of tissue than does a dual-channel endoscope <xref rid="JR010-9" ref-type="bibr">9</xref>
. It has been tested in both bench top and in vivo animal studies in the performance of transgastric small-bowel resection and intra-abdominal exploration <xref rid="JR010-10" ref-type="bibr">10</xref>
. Aspects for which potential improvements should be be considered include the complex control, which causes a delay in the end effectors, and the retroflexion capabilities; in addition, the optics are housed in the shaft, creating inadequate visualization as a result of the long distance between the instruments and lens. Accurate dissection with one arm of the device while larger organs, such as bowel, are retracted can be difficult because of inadequate mobility. </p>
</sec>
<sec><title>ANUBIScope (Karl Storz, Tuttlingen, Germany)</title>
<p>Storz and IRCAD (Institut de Recherche contre les Cancers de l’Appareil Digestif)) collaborated in the ANUBIS project <xref rid="JR010-11" ref-type="bibr">11</xref>
to develop this reusable flexible platform in 2005. A four-way articulating flexible endoscopic shaft, 16 mm in diameter, provides endoscope-style navigation and maneuverability. The 18-mm articulating distal tip has a novel tulip shape comprising two wings that remain closed during entry, acting as a blunt trocar to prevent injury. The wings, with a 4.2-mm working channel in each, open in the working configuration, allowing two opposing arms to emerge. This distal configuration enables the triangulation of up to three articulated instruments, although the wings limit the maneuverability of the device in confined spaces, such as a lumen. A further 3.4-mm central channel is located in the shaft. </p>
<p>Control of the arms is achieved by manipulation of the introduced tools down the working channels, enabling faster working times in the absence of a control interface. A number of animal and cadaveric studies have been performed. Successful procedures include distal pancreatectomy <xref rid="JR010-12" ref-type="bibr">12</xref>
, sigmoidectomy <xref rid="JR010-13" ref-type="bibr">13</xref>
, and transgastric cholecystectomy <xref rid="JR010-14" ref-type="bibr">14</xref>
<xref rid="JR010-15" ref-type="bibr">15</xref>
. The first successful transvaginal cholecystectomy with the device, performed in 60 minutes, was recently published <xref rid="JR010-16" ref-type="bibr">16</xref>
. </p>
<p>These studies have highlighted some limitations, including difficulties with gastrotomy closure and with spatial orientation and retraction when the instrument is in a retroflexed position. Visualization is affected by the integrated optics, and stability of the platform is achieved by fixation to a stand. Improvements to create an articulated device with adequate triangulation of instruments and stability, allowing the resection of lesions in retroflexion and in awkward configurations, could be made.</p>
</sec>
<sec><title>R-Scope (Olympus)</title>
<p>This 13.5-mm-diameter flexible dual-channel endoscope was developed by Olympus for endoscopic submucosal dissection <xref rid="JR010-17" ref-type="bibr">17</xref>
<xref rid="JR010-18" ref-type="bibr">18</xref>
, but it has potential for NOTES and other ELS procedures. It addresses common challenges posed by the dual-channel endoscope, including triangulation of instruments, positioning, and stability. Earlier prototypes had multibending, separately controllable segments <xref rid="JR010-19" ref-type="bibr">19</xref>
; although an advance on the M-scope (Olympus), this feature is not present on the current model as difficulties arose during retroflexion and it was felt that it added little to the maneuvering ability. </p>
<p>There are two articulated 2.8-mm working channels with horizontal and vertical lifting gates, positioned 90° to each other. This configuration allows simultaneous but separate movements of instruments in perpendicular planes, improving the accuracy of off-axis movements during tissue dissection.</p>
<p>The platform has been used to perform a number of procedures, including transgastric cholecystectomy <xref rid="JR010-20" ref-type="bibr">20</xref>
, distal pancreatectomy <xref rid="JR010-21" ref-type="bibr">21</xref>
, and endoscopic submucosal dissection <xref rid="JR010-22" ref-type="bibr">22</xref>
. The platform improves traction and countertraction of tissue in in vivo studies <xref rid="JR010-23" ref-type="bibr">23</xref>
and has been shown to reduce gastric endoscopic submucosal dissection procedural time <xref rid="JR010-22" ref-type="bibr">22</xref>
. However, bimanual coordination without the aid of a laparoscopic port – for example, for liver retraction during cholecystectomy – can be difficult. </p>
<p>Although the R-Scope is an improvement on the dual-channel endoscope, further improvements to the stability of the device, ability to perform precise dissection, and degrees of freedom of the platform <xref rid="JR010-23" ref-type="bibr">23</xref>
<xref rid="JR010-24" ref-type="bibr">24</xref>
are required. Furthermore, the operator can easily become disorientated when the instrument is in the retroflexed position; the field of view can be limited, and coordination of the platform remains problematic. </p>
</sec>
<sec><title>Incisionless operating platform (USGI Medical, San Clemente, CA, USA)</title>
<p>This flexible multilumen platform consists of the multitasking TransPort device and tools for tissue approximation, manipulation, and suturing. The TransPort device is a flexible, steerable oversheath, 18 mm in diameter, with conventional endoscopic control mechanisms. Four working channels (7, 6, 4, and 4 mm) allow a variety of instruments to be used interchangeably, enabling tissue manipulation and resection. Visualization is achieved by inserting a flexible endoscope, such as an N-scope (Olympus), into the 6-mm channel and irrigation down another channel. Four-way flexibility of the distal tip allows fine precision control, enhanced deflection, and adjustable visual horizon control.</p>
<p>The ShapeLock function of the oversheath of this ergonomic platform, which improves stability, is a novel feature of the device. A series of titanium rings allows the flexible shaft to be stiffened once in position, improving the stability <xref rid="JR010-25" ref-type="bibr">25</xref>
, lifting strength, and torsion abilities compared with a conventional endoscope <xref rid="JR010-26" ref-type="bibr">26</xref>
. </p>
<p>The device has been tested extensively in animals and humans; the first transgastric cholecystectomy was performed in 2007. Gastric fundoplication, diaphragmatic hernia repair, and hybrid laparoscopic/NOTES procedures in humans, such as transgastric and transvaginal cholecystectomies, have been performed <xref rid="JR010-27" ref-type="bibr">27</xref>
<xref rid="JR010-28" ref-type="bibr">28</xref>
<xref rid="JR010-29" ref-type="bibr">29</xref>
<xref rid="JR010-30" ref-type="bibr">30</xref>
. These encouraging studies have highlighted some needed improvements to the platform; rectification could significantly enhance its performance.</p>
<p>A lack of integrated optics in the device means that the optics are housed in one of the four working channels; the arrangement of the working channels may limit the effective working space, and smooth, precise control of the distal tip can be difficult. Skilled operators and assistants are required for scope navigation, positioning, and orientation and for instrument exchange, rendering this a stable but challenging platform. </p>
<p>The USGI Cobra device was designed to address the difficulties in the triangulation of instruments encountered with the TransPort device. A 6-mm flexible endoscope could be passed through the center of the device, and shape-lock technology enabled locking of the device once in place. Two arms enabled tissue manipulation; however, the whole platform had to be removed in order to exchange tools <xref rid="JR010-31" ref-type="bibr">31</xref>
. Precise dissection was also problematic because of imprecise cable-driven controls, and ultimately this device was abandoned in 2012.</p>
</sec>
<sec><title>Direct Drive Endoscopic System (Boston Scientific, Natick, MA, USA)</title>
<p>This platform consists of a flexible controllable sheath steered with conventional endoscopic controls, a mobile rail system that can fix the platform directly to the operating table, and 4-mm articulated flexible controllable instruments <xref rid="JR010-32" ref-type="bibr">32</xref>
.</p>
<p>Three working channels are housed within the sheath that allow passage of a small (< 6 mm) endoscope, providing independent flexible optics down a 6-mm channel. There are also two 4-mm multidirectional tendon-driven instruments that contribute to the seven degrees of freedom of motion the platform allows (two at the shaft and five at the distal instrument tip). Their working length can extend to 12 cm beyond the distal end of the sheath and are controlled by two ergonomic handles. </p>
<p>Although the platform has been successfully used in animal studies, its translation to human studies will require further modification of the platform. It was shown to be superior to both the dual-channel endoscope and R-Scope with respect to bench top experiments, reducing procedural time and improving bimanual coordination <xref rid="JR010-33" ref-type="bibr">33</xref>
<xref rid="JR010-34" ref-type="bibr">34</xref>
. However, a shaft length of 55 cm in total limits procedures in certain areas, such as the proximal colon and beyond the stomach. </p>
<p>If this system is to be a platform that has multiprocedural capabilities, changes to the sheath to improve torque need to be made. Difficulties with the parallel orientation of the forceps, interfering with the optical axis, and repeated recalibrations to the rail system also require correction to decrease disturbances during procedures. Furthermore, despite the platform-specific instruments that improve triangulation and tissue dissection, only a limited number of types are available.</p>

<sec><title>Robotic platforms</title>
<p>A summary of robotic platforms appears in <xref rid="TB010-3" ref-type="table">Table 3</xref>
. The snakelike model is preferred for natural orifice “scarless” surgery to be achieved (<xref rid="FI010-2a" ref-type="fig">Fig. 2</xref>
). A number of emerging robots are in the research phase of development that could have a role in endoluminal surgery. Current devices developed for endoluminal procedures require modification of their design to accommodate the restrictive workspace. Simaan and colleagues have developed a tele-robotic system for deep access to tight workspaces, such as the oropharynx <xref rid="JR010-35" ref-type="bibr">35</xref>
. This dual-arm slave robot has actuated distal dexterity units that are able to transmit rotation along their backbones, allowing movement in 20 degrees of freedom. This has potential for application in myriad procedures, including endoluminal surgery, neurosurgery, and fetal surgery.</p>

<p>Another promising robot for endoluminal surgery is a four-jointed snakelike robot developed by Choset and colleagues. Each joint enables movement in three degrees of freedom, allowing 12 degrees of freedom of movement in total. In addition, each joint can produce 5 Nm of torque, a highly desirable feature <xref rid="JR010-36" ref-type="bibr">36</xref>
. </p>
<p>One of the most exciting ventures is the “array of robots augmenting the kinematics of endoluminal surgery” (ARAKNES) project <xref rid="JR010-37" ref-type="bibr">37</xref>
. This team has endeavored to develop a micro-robot – based operating system to advance minimally invasive surgery. Bimanual tele-operated robots equipped with micro-robotic instruments equivalent to those of laparoscopic surgical robots can perform surgery for conditions such as obesity and gastroesophageal reflux disease.</p>
<sec><title>NeoGuide Endoscopy System (Intuitive Surgical, Sunnyvale, CA, USA)</title>
<p>This is a novel computer-assisted colonoscope that provides real-time three-dimensional mapping of the colonoscope to reduce looping and pain during colonoscopy. The flexible shaft consists of 16 segments, each measuring 8 cm, that allow automatic shape control of the shaft. During manual insertion, the position and angle of the distal, leading segment tip are encoded in a computer algorithm with position sensors. This results in articulation of the shaft based on mapping of the tip configuration during insertion. The subsequent 15 coupled segments then follow in a “follow-the-leader” fashion. As a result, the operator has a luminal view of the colon as well as a simultaneous image of the tip position and insertional tube shape. </p>
<p>Bench top studies of colonic models have shown a reduction of lateral forces and a reduction in looping compared with conventional colonoscopes <xref rid="JR010-38" ref-type="bibr">38</xref>
. A study has also shown that the NeoGuide provides accurate information regarding looping, tip position, and insertional tube position <xref rid="JR010-39" ref-type="bibr">39</xref>
. A feasibility study has shown it to be an effective and safe platform, with successful navigation to the cecum in 10 patients <xref rid="JR010-40" ref-type="bibr">40</xref>
. In addition, this study showed physician and patient satisfaction with the platform. Although this is a single-operator platform, all the procedures were performed by two operators: one to inserted the tube manually and another to steer the platform. </p>
<p>This is a promising flexible prototype with the potential to perform complex endoluminal procedures. Further larger-scale human studies are now warranted to improve it.</p>
</sec>
<sec><title>Master-slave system for NOTES (IRCAD, Strasbourg, France)</title>
<p>This master-slave tele-operated robot was designed in collaboration with Karl Storz. The slave component has two hollow, flexible, snakelike, tendon-driven arms through which instruments can be inserted and operated, providing movement in two degrees of freedom <xref rid="JR010-41" ref-type="bibr">41</xref>
. The slave component is attached to the distal tip of an endoscope with a specially designed cap to provide triangulation of the instruments by deflection of the arms away from the scope axis. Rotation and translation of passive movements can be decoupled and controlled separately. </p>
<p>The master console is a desklike workstation, and the system can provide up to 12 degrees of freedom in total. The main drawback of this robot is that the attachments are large and cumbersome; a carrying cart is needed to hold the slave arms and motorized endoscope in place.</p>
</sec>
<sec><title>ViaCath robot (Hansen Medical, Mountain View, CA, USA)</title>
<p>This robot, developed by EndoVia Medical (now Hansen Medical) <xref rid="JR010-42" ref-type="bibr">42</xref>
, consists of an ergonomically designed master control system and haptic interface mechanisms within a desk-workstation design. Thumb control buttons on the master control handles allow a swift change of instruments and system settings, and they fix the platform into place. The slave system consists of an articulated overtube that is able to introduce a flexible endoscope and two highly articulated instruments with six degrees of freedom. ViaCath flexible instruments are 90 cm long with an articulating end effector tip. The distal tip has a double flex section, allowing an S curve to be generated for accurate orientation of the custom-made end effectors, which include graspers, electrocautery knives, and needle holders. </p>
<p>Improvements to the instruments and overtube are in development to overcome problems experienced during intubation of the patient and instrument positioning, and to increase the force generated at the distal instrument tip for adequate tissue manipulation. </p>
</sec>
<sec><title>MASTER (Nanyang University, Singapore)</title>
<p>The master and slave transluminal endoscopic robot (MASTER) was developed by Phee and colleagues in Singapore <xref rid="JR010-43" ref-type="bibr">43</xref>
<xref rid="JR010-44" ref-type="bibr">44</xref>
. The robot consists of a tele-surgical workstation, a master console, and a flexible slave manipulator. The slave component has two motor-driven end effectors (a grasper and a monopolar electrocautery hook) mounted on the tip of two actuated arms attached to a conventional endoscope <xref rid="JR010-45" ref-type="bibr">45</xref>
. This allows movement in seven degrees of freedom by tendon activation and in two by direct drive. The system has been used to perform in vivo NOTES procedures, including cholecystectomy, liver resections <xref rid="JR010-46" ref-type="bibr">46</xref>
, and gastric endoscopic submucosal dissection <xref rid="JR010-47" ref-type="bibr">47</xref>
<xref rid="JR010-48" ref-type="bibr">48</xref>
. </p>
<p>Despite these encouraging studies, difficulties with the platform remain. Friction in the tendon sheath causes a delay in the operation of the master controller, inhibiting seamless surgery. The end effectors are fixed, so that surgery is limited to the use of these instruments and insertion also requires an overtube. Precision of the arms is compromised by retroflexion of the scope, and furthermore, questions regarding the sterilization process and gastrotomy closure remain unanswered, hindering its use.</p>
</sec>
<sec><title>i-Snake (Hamlyn Centre, Imperial College, London, United Kingdom)</title>
<p>This multiarticulated bio-inspired snake robot is 150 mm long and 12.7 mm in diameter, with a 50-mm semirigid neck. It is based upon a universal joint mechanism with embedded micro-motor actuation <xref rid="JR010-49" ref-type="bibr">49</xref>
. The distal tip is articulated with four distal joints that can be independently controlled, permitting eight degrees of freedom. Position control of the motorized joints allows precise motions of the robot for accurate dissection and tissue handling. </p>
<p>An on-board camera and light source are housed within the flexible shaft, and two 3-mm working channels allow flexible instruments to be used interchangeably. The snake is guided by the operator with an ergonomic hand-held interface. This allows realignment of the motor-visual axes of the operator, allowing them to remain oriented during the procedure. Preliminary tubal ligation studies <xref rid="JR010-50" ref-type="bibr">50</xref>
and feasibility studies for robotic gastric endoscopic submucosal dissection and peroral endoscopic myotomy are being carried out. </p>
</sec>
</sec>
<sec><title>Engineering problems, developments, and the future</title>
<p>The evolution of a multitasking flexible platform for NOTES and ELS is still in flux. Current surgical and endoscopic platforms and their instrumentation are characterized by technical limitations that affect their performance and large-scale application. </p>
<p>A technical limitation of a number of platforms is inadequate triangulation of instruments. Balloons may be useful in the esophagus but are unlikely to be of use in a large cavity, such as the stomach. Several solutions have been considered to address this issue, including telescopic camera holders, angled vision endoscopes, and instruments provided with elbows able to align the axis. </p>
<p>Potential solutions to tight endoluminal workspaces are compact wristed bimanual instruments, which may increase instrument dexterity; however, the ideal force required at the instrument tip is about 9 N to enable robust tissue manipulation . Reaching these force requirements is challenging, and it is estimated that endoscopic instruments apply only 20 % of the force that laparoscopic tools are able to apply <xref rid="JR010-51" ref-type="bibr">51</xref>
. </p>
<p>Although the basic design of the endoscope has changed little since it was developed, a paradigm shift in flexible endoscopy and a surge of new technologies may lead to a new generation of interventional multitasking endoscopes, allowing the firm integration of NOTES and ELS into routine practice. Miniature robots, micro-robots, wireless technologies, soft robotics, and magnets are among the emerging technologies that may impact the future of NOTES and ELS. Could this in turn pave the way for a new generation of operators – hybrid gastroenterologists and surgeons?</p>
