Abstract:

In the last 20 years, there have been important developments in endoscopy. Initially, endoscopy was developed and used as a diagnostic tool. As new technology developed, these devices also became the basis for therapeutic maneuvers. In recent years, flexible endoscopes have been used to per- form procedures replacing traditional surgical approaches. Examples of this field are transanal minimally invasive surgery, natural orifice transluminal endoscopic surgery, endoscopic metabolic surgery and third space endoscopies. Throughout history, surgeons have played a vital role in the design and development of endoscopic techniques, procedures, and equipment. Surgeons continue to lead the advancement of endoscopy, make important contributions, and serve as role models for innovation.

AbstractObjectives:To summarise published research investigating maximal temperatures associated with endoscopes used in otology. Possible thermal issues surrounding the use of endoscopes in middle-ear surgery are discussed, and recommendations regarding the safest ways to use endoscopes in endoscopic ear surgery are made.Methods:A non-systematic review of the relevant literature was conducted, with descriptive analysis and presentation of the results.Results:There are currently no reports of any temperature-related deleterious effects in patients having undergone endoscopic ear surgery. There is debate regarding heat issues in endoscopic ear surgery, with a limited body of work documenting potential negative impacts of middle-ear heat exposure from endoscopes. The diameter of endoscope, type of light source used, distance from endoscope tip and duration of exposure are highlighted potential factors for high temperatures in endoscopic ear surgery.Conclusion:There is a trend towards endoscopes being used routinely in ear surgery. Simple practice points are recommended to minimise potential thermal risks.

Abstract:

The use of endoscope in the field of ear surgery has done the revolutionary changes. The optical advantage of endoscope helps the otologist to perform the stapes surgery very conveniently. The main advantage of the endoscope in stapes surgery over the microscope is; the better preservation rates of the chorda tympani nerve (CTN), minimal curetting of the outer attic wall, hence minimizing the iatrogenic injury to the CTN. Apart from that, the audiometric results following the endoscopic stapes surgery is comparable with the microscopic surgery. We had performed the stapes surgery with the rigid nasal endoscopes (Karl Storz) of 4-mm diameter and 18-cm length. Our preliminary results showed that transcanal endoscopic stapedotomy is a reliable and safe technique for the surgical management of otosclerosis.

Abstract:

Abstract OBJECTIVE We describe a novel 3-dimensional (3-D) stereoendoscope and discuss our early experience using it to provide improved depth perception during transsphenoidal pituitary surgery. METHODS Thirteen patients underwent endonasal endoscopic transsphenoidal surgery. A 6.5-, 4.9-, or 4.0-mm, 0- and 30-degree rigid 3-D stereoendoscope (Visionsense, Ltd., Petach Tikva, Israel) was used in all cases. The endoscope is based on “compound eye” technology, incorporating a microarray of lenses. Patients were followed prospectively and compared with a matched group of patients who underwent endoscopic surgery with a 2-dimensional (2-D) endoscope. Surgeon comfort and/or complaints regarding the endoscope were recorded. RESULTS The 3-D endoscope was used as the sole method of visualization to remove 10 pituitary adenomas, 1 cystic xanthogranuloma, 1 metastasis, and 1 cavernous sinus hemangioma. Improved depth perception without eye strain or headache was noted by the surgeons. There were no intraoperative complications. All patients without cavernous sinus extension (7of 9 patients) had gross tumor removal. There were no significant differences in operative time, length of stay, or extent of resection compared with cases in which a 2-D endoscope was used. Subjective depth perception was improved compared with standard 2-D scopes. CONCLUSION In this first reported series of purely 3-D endoscopic transsphenoidal pituitary surgery, we demonstrate subjectively improved depth perception and excellent outcomes with no increase in operative time. Three-dimensional endoscopes may become the standard tool for minimal access neurosurgery.

Abstract:

EnAbstract Objective The purpose of this study was to evaluate the role of middle-ear endoscopy in the effective control over cholesteatoma through visualizing hidden areas of the middle-ear cleft. Materials and methods A total of 60 ears with retraction pocket cholesteatoma were operated upon. They were subdivided into 40 cases operated upon using the canal wall up technique and another 20 cases operated upon using transcanal atticotomy. Endoscopically guided ear surgery was incorporated complementary to the microscope as a principal part in the procedure. Results The incidence of cholesteatoma in the facial recess that was visualized by the endoscope was 25% compared with 20% by the microscope, whereas the incidence of detection of cholesteatoma in the sinus tympani by the endoscope was 35% compared with 5% by the microscope. Cholesteatoma in the anterior epitympanic recess was detected by the endoscope in 10% of ears compared with 0% by the microscope. In this series, no morbidity or complication was encountered secondary to the use of endoscopes in the mastoid or the middle ear. Conclusion Endoscope-assisted ear surgery has many benefits in cholesteatoma surgery as endoscopy helps explore hidden areas of the middle-ear cavity with a much lesser requirement for surgical exposure and the need to drill healthy bone; therefore, effective control over the disease can be achieved, thus establishing the concept of functional endoscopic ear surgery.

Abstract:

AbstractBackgroundThree-dimensional endoscopes provide a stereoscopic view of the operating field, facilitating depth perception compared to two-dimensional systems, but are not yet widely accepted. Existing research addresses performance and preference, but there are no studies that quantify anatomical orientation in endoscopic ear surgery.MethodsParticipants (n = 70) were randomised in starting with either the two-dimensional or three-dimensional endoscope system to perform one of two tasks: anatomical orientation using a labelled three-dimensional printed silicone model of the middle ear, or simulated endoscopic skills. Scores and time to task completion were recorded, as well as self-reported difficulty, confidence and preference.ResultsNovice surgeons scored significantly higher in a test of anatomical orientation using three-dimensional compared to two-dimensional endoscopy (p < 0.001), with no significant difference in the speed of simulated endoscopic skills task completion. For both tasks, there was lower self-reported difficulty and increased confidence when using the three-dimensional endoscope. Participants preferred three-dimensional over two-dimensional endoscopy for both tasks.ConclusionThe findings demonstrate the superiority of three-dimensional endoscopy in anatomical orientation, specific to endoscopic ear surgery, with statistically indistinguishable performance in a skills task using a simulated trainer.

Abstract:

Abstract Background: Anterior clinoidectomy is an essential preliminary step for parasellar and pericavernous sinus surgery. Endoscopy is a widely accepted modality for neurosurgical strategies and is becoming more important in treating conditions involving the cranial base. Objective: To determine the feasibility of endoscopic extradural anterior clinoidectomy via the supraorbital keyhole. Methods: Eight fresh cadaver heads were studied using 4-mm, 0- and 30-degree rigid endoscopes to perform endoscopic extradural anterior clinoidectomy. We also evaluated a bony landmark for this technique in 36 dry craniums. Results: An endoscope was introduced into the extradural space created via a supraorbital keyhole craniotomy. The periorbita and the duplication of the dura extending to the temporal lobe dura and periorbita were exposed by drilling. Anterior clinoidectomy proceeded using a diamond drill under endoscopic visualization without a dural incision. A submerged view with continuous irrigation through an endoscopic sheath maintained clear visibility while drilling. A small bony eminence at the transition between the sphenoid ridge and the anterior clinoid process, which is an anatomic landmark for endoscopic extradural anterior clinoidectomy, was identified in 57.4% of 36 adult dry craniums. Conclusion: The endoscopic extradural procedure can accomplish reliable anterior clinoidectomy under superb endoscopic visualization. This method would be applicable to parasellar and cavernous sinus surgery combined with keyhole or conventional craniotomy.

Abstract:

Abstract BACKGROUND: The endoscope is being introduced as an adjuvant to improve visualization of certain areas in open cranial surgery. OBJECTIVE: To describe the endoscopic anatomy of common aneurysm sites and to compare it with the microsurgical anatomy. METHODS: Pterional, anterior interhemispheric, and subtemporal approaches to the most common aneurysm sites were examined in cadaveric heads under the surgical microscope and with the endoscope. RESULTS: The endoscopic view, particularly with the angled endoscopes, provides a significant improvement compared with the microscopic view, especially for poorly visualized sites such as the medial aspect of the supraclinoid carotid artery and its branches, the area below the anterior perforated substance and optic tract, and the carotid and basilar bifurcations. The endoscope aided in the early visualization of perforating branches at each aneurysm site except the middle cerebral artery. Small-diameter optics (2.7 mm) provided greater space for dissection and less potential for tissue damage in narrow places, whereas the larger 4-mm diameter optics provided better visualization and less panoramic distortion. The positioning of the endoscope for each aneurysm site is reviewed. CONCLUSION: The endoscope provides views that complement or improve the microscopic view at each aneurysm site except the middle cerebral artery. Endoscopy training and a thorough knowledge of endoscopic vascular anatomy are essential to safely introduce endoscopic assistance in vascular surgery.

Abstract:

OBJECTIVE: We describe a new endoscopic transethmoid approach for pituitary surgery and to compare it with other surgical techniques. STUDY DESIGN AND SETTING: Eleven patients undergoing pituitary surgery from September 2000 through January 2002 underwent an image-guided endoscopic transethmoid procedure to remove pituitary tumors. Ease of approach, resection, exposure of the surgical field, and operative complications were documented. RESULTS: Endoscopic ethmoidectomy permits enhanced exposure and simplified tumor resection. The use of one nostril to stabilize the endoscope and the other to pass instruments affords a bimanual procedure that avoids the difficulty of small nares and keeping the scope fixed while exchanging instruments. Operative morbidity was low with no significant complications in this pilot study. CONCLUSIONS: This approach opens a generous operative exposure while safely allowing room to endoscopically maneuver and affords direct access should revision surgery be needed. SIGNIFICANCE: This procedure uses a technique familiar to otolaryngologists and may be used for pituitary and other skull base tumors. The transseptal approach to the sella turcica is the most commonly performed procedure to reach the pituitary gland. Three major variations of the transseptal approach are used: sublabial approach, external rhinoplasty approach, and transnasal approach. Each has unique advantages and disadvantages relative to each other and the endoscopic procedure, apart from the shared transseptal route ( Table 1 ). The techniques have been described elsewhere previously. 1–3 More recently, endoscopy has been used to aid the approach to the pituitary. The first endoscopic procedures used the transseptal dissection route through a standard sublabial incision, with the endoscope passed through a self-retaining speculum. 4–6 In other cases the endoscope was used for the approach only, with the binocular operating microscope subsequently used for the tumor resection. 7 Except for the wide field of vision afforded by the endoscopic approach, the morbidity of a transseptal dissection remained. More recent advances have used an endonasal approach, which allows the surgeon to bypass the transseptal dissection. 8–11 The majority of procedures performed use one nostril to pass the endoscope and other instruments, with limited endoscopic operative maneuverability. We introduce an endonasal transethmoid approach bypassing the need for a nasal retractor, headrest, and postoperative nasal packing, while providing enhanced endoscopic operative maneuverability through bimanual instrumentation using both nares and an endoscope stabilizer.

Abstract:

Abstract BACKGROUND: Three-dimensional (3-D) endoscopy is a recent addition to augment the transsphenoidal surgical approach for anterior skull-base and parasellar lesions. We describe our experience implementing this technology into regular surgical practice. OBJECTIVE: Retrospective review of clinical factors and outcomes. METHODS: All patients were analyzed who had endoscopic endonasal parasellar operations since the introduction of the 3-D endoscope to our practice. Over an 18-month period, 160 operations were performed using solely endoscopic techniques. Sixty-five of these were with the Visionsense VSII 3-D endoscope and 95 utilized 2-dimensional (2-D) high-definition (HD) Storz endoscopes. Intraoperative and postoperative findings were analyzed in a retrospective fashion. RESULTS: Comparing both groups, there was no significant difference in total or surgical operating room times comparing the 2-D HD and 3-D endoscopes (239 minutes vs 229 minutes, P = .47). Within disease-specific comparison, pituitary adenoma resection was significantly shorter utilizing the 3-D endoscope (surgical time 174 minutes vs 147 minutes, P = .03). These findings were independent of resident or fellow experience. There was no significant difference in the rate of complication, reoperation, tumor resection, or intraoperative cerebrospinal fluid leaks. Subjectively, the 3-D endoscope offered increased agility with 3-D techniques such as exposing the sphenoid rostrum, drilling sphenoidal septations, and identifying bony landmarks and suprasellar structures. CONCLUSION: The 3-D endoscope is a useful alternative to the 2-D HD endoscope for transnasal anterior skull-base surgery. Preliminary results suggest it is more efficient surgically and has a shorter learning curve. As 3-D technology and resolution improve, it should serve to be an invaluable tool for neuroendoscopy.

Abstract:

Throughout history, developments in medicine have aimed to improve patient quality of life, and reduce the trauma associated with surgical treatment. Surgical access to internal organs and bodily structures has been traditionally via large incisions. Endoscopic surgery presents a technique for surgical access via small (1 Omm) incisions by utilising a scope and camera for visualisation of the operative site. Endoscopy presents enormous benefits for patients in terms of lower post operative discomfort, and reduced recovery and hospitalisation time. Since the first gall bladder extraction operation was performed in France in 1987, endoscopic surgery has been embraced by the international medical community. With the adoption of the new technique, new problems never previously encountered in open surgery, were revealed. One such problem is that the removal of large tissue specimens and organs is restricted by the small incision size. Instruments have been developed to address this problem however none of the devices provide a totally satisfactory solution. They have a number of critical weaknesses: -The size of the access incision has to be enlarged, thereby compromising the entire endoscopic approach to surgery. - The physical quality of the specimen extracted is very poor and is not suitable to conduct the necessary post operative pathological examinations. -The safety of both the patient and the physician is jeopardised. The problem of tissue and organ extraction at endoscopy is investigated and addressed. In addition to background information covering endoscopic surgery, this thesis describes the entire approach to the design problem, and the steps taken before arriving at the final solution. This thesis contributes to the body of knowledge associated with the development of endoscopic surgical instruments. A new product capable of extracting large tissue specimens and organs in endoscopy is the final outcome of the research.

Abstract:

Background: Endoscopic ear surgery has gained acceptance as a complementary tool to microscopic ear surgery, but perhaps not so much as an instrument for exclusive use.With this approach becoming popular, there is scarce data on cholesteatoma recidivism and hearing outcomes, when exclusively used. Objectives: Auditing outcomes of endoscopic ear surgery for the surgical management of cholesteatoma in the Groote Schuur hospital (above13 year age group) and the Red Cross War Memorial Children’s hospital (below 13 year age group) , with a secondary aim of comparing recidivism and hearing outcomes of 4 different surgical techniques for cholesteatoma resection, namely, exclusive endoscopic (EES), microscopic canal wall down (CWD), microscopic canal wall up (CWU) and combined endoscopic-microscopic techniques. Methods: A retrospective chart review was conducted at our two tertiary academic referral hospitals in Cape Town, namely, Red Cross War Memorial Children’s Hospital and Groote Schuur Hospital from January 2012 to December 2016. Results: A total of 128 cholesteatoma ear surgeries were done; 110 patients were above the age of 13 years and 18 patients were below the age of 13 years. Eight Red Cross patients underwent EES, 7 had CWU, 2 had CWD and 1 had a combined technique. Overall recidivism rate in this population was 33% (6/18), of which 2 were approached exclusively endoscopically, 2 underwent a microscopic CWU, 1 had a CWD and 1 had combined endoscopic-microscopic approach. The mean postoperative hearing in this group was 40dB compared to a preoperative mean of 50,3 decibels (dB). In the Groote Schuur group, 23 underwent an exclusive endoscopic approach; 42 had a CWU, 40 had a CWD and 5 had a combined endoscopic-microscopic approach. Overall recidivism rate for the above 13 year old group was 17% (19/110). Of those, 7 were from the endoscopic group, 8 from the CWU group, 1 from CWD group and 3 from the combined technique group. Mean postoperative hearing was 47,4dB compared to a preoperative hearing of 48,4dB. Conclusions: The CWD technique demonstrated superior outcomes in both the above and below 13 year age groups. In the above 13 year old group, the EES approach had the same recurrence rate as CWU. While paediatric cholesteatomas have much higher recidivism rates compared to adults, our below 13 year old group was too small to conclude any statistical significant differences between the different approaches, and therefore, further studies are required in this age group. Management of cholesteatoma requires a highly individualized approach that takes into account anatomic, clinical and social factors to determine the most appropriate surgical treatment paradigm

Abstract:

Endoscopic nasal surgery is with minimal invasiveness for the surgical treatment of nasal disease. During traditional functional endoscopic sinus surgery (FESS), the surgeon uses one hand to hold the surgical instrument leaving the other hand to hold the endoscope. When the surgeon needs to use two hands to perform some complex procedure, an assistant surgeon is required to help holding the endoscope, and this requires good teamwork and long-time training. To solve this problem, researchers proposed to use robots to hold the endoscope, freeing the surgeon’s hands for bimanual operation. Sun developed a passive arm with pneumatic locking mechanism to hold the endoscope in FESS, but the surgeon needs to adjust the pose of the endoscope manually, which interrupts the surgery flow and lengthens the surgery time [1]. Many motor-driven endoscope holders have been proposed in literature [2], the surgeon interact with the robot with joystick, voice command, pedals or head movement [3–5]. However, there exists some drawbacks with these interacting methods, for example, joystick requires one of the surgeon’s hands, voice command is usually subject to interference and has long time-delay, foot pedals and head movement distract surgeon’s attention. Lin used a foot-attached IMU sensor to control an active robotic endoscopic holder, the inversion/eversion and abduction/adduction motions of foot are used to select and control different joints, but the motor can be only selected in order, which is unhandy for the four-joint scenario [6]. In this paper, a similar foot-attached IMU sensor is used, and the joints are selected in an easier manner, based on the angle of plantarflexion. Rather than the angle, the angular velocity of abduction/adduction is utilized to control the moving direction of the active joint. This paper describes the test result of the proposed control interface.

Abstract:

Flexible endoscopes are widely used due to their effective treatment of various conditions with minimal surgery. Existing ESD platform, such as Incisionless operation platform (IOP) [1] and ANUBIScope [2], while they may offer reliable support for endoscopic bending, they lack the ability to provide precise motorized motion or may potentially restrict the maneuverability of the platform in confined endoluminal environments. Another more advanced operation platform, namely EndoMaster [3], while providing excellent visualization of the surgical area due to its compact design, which allowed for easy docking and prevented interference from the working arms, however, its complex operational requirements, where the surgeon must control the console remotely and manipulate the robotic arms using hand controls, can be time-consuming and challenging for the surgeon to master. Over-the-Scope Clip (OTSC) [4] use a device that places clips over the endoscope to hold tissue before removal, but the effectiveness of these clips in securing the tissue is sometimes inadequate, resulting in incomplete tissue acquisition and suboptimal surgical outcomes. Existing operating systems face challenges such as limited mobility, insufficient tissue collection, complex setup, and high costs. EndoGRASP, a novel handheld endoscopic platform, addresses these issues with its flexible robotic overtube and actuation unit. Optimized for efficient endoscopic submucosal dissection, it enhances patient safety and ensures precise, motorized control of the endoscope and instruments.

Abstract:

Natural orifice transluminal endoscopic surgery (NOTES) is a novel surgical technique which uses endoscopic tools to perform mini invasive abdominal operations through natural orifices. The main limitation for a secure use of this technique is the lack of a proper surgical device, since it is still performed by non rigid endoscopes designed for diagnostic applications. Robot Assisted Surgery is the ideal solution to perform this kind of surgical operations. This research project is a preliminary study for the design of an endoscope, with variable stiffness in effort to provide the surgeons with a device which meets specific clinical requirements. The body is composed of a series of robotic modules connected by joints capable of two different movements: an axial rotation and a longitudinal bending. The movements are servo commanded and carried out by two brushless DC electric motors and an encoder. A force sensor is mounted on each module in order to provide a haptic feedback to the surgeon. The end point of the robot is equipped with a high definition camera which is able to perform zoom, autofocus and image stabilization. Illumination is provided by a power led system. A CAN bus ensures the communication between the modules, the camera and the haptic interface.

Abstract:

Robot-assisted minimally invasive surgery (MIS) has countless benefits over open surgery, from shorter re- covery times and lower risk procedures for the patient to higher accuracy and broader capabilities for the surgeon [1]. However, a significant detriment to these procedures is that current systems lack haptic feedback. The lack of haptic feedback in MIS forces the surgeon to depend merely on visual cues, such as the deformation of tissue under load, to estimate the forces [1]. The likely outcome of misreading these cues is torn tissue, patient discomfort or broken sutures [2]. Moreover, haptic feed- back is specifically vital for robot-assisted endoscopy procedures. A recent study evaluating an Endoscopic Operation Robot (EOR) concluded that haptic feedback is beneficial in remote manipulation of flexible endo- scopes. When haptic feedback was absent there were more incidences of overstretching of sigmoid colon in a colonoscopy training model [3]. This work presents a soft robotic glove that provides haptic feedback for endoscopic procedures (Fig. 1, A). In our previous work, we introduced a soft robotic sleeve [4] that can detect forces between a colonoscope and colon walls during navigation. The glove receives force input from the soft robotic sleeve wrapped around the colonoscope (Fig. 1, B). Any incident force on the sleeve, during endoscopic navigation, is relayed to the surgeon as haptic feedback through proportional inflation of the glove’s pneumatic actuators.

Abstract:

Natural Orifice Translumenal Endoscopic Surgery (NOTES) promises to reduce the invasiveness of surgical procedures by accessing the peritoneal cavity through a natural orifice. Current tools for performing NOTES are based on the flexible endoscopy platform, and are significantly limited in imaging and manipulation by the size and geometry of the natural lumen. For NOTES to revolutionize minimally invasive surgery, new approaches are necessary that enable the surgeon to perform procedures with vision and dexterity equivalent to laparoscopic procedures. An image-guided, two-armed, dexterous miniature NOTES robot has been developed that can be placed into the peritoneal cavity through a transgastric incision. Using this robot, the surgeon has effectively demonstrated tissue dissection in non-survivable animal model procedures. A next step in the development of miniature in vivo robots is the automation of routinely performed, low level surgical tasks. This paper details work towards autonomous tissue dissection using the NOTES robot. As a first step, visual tracking and robot control methods are being developed.

Abstract:

Flexible endoscopes are mainly used for diagnostics and performing simple therapeutic tasks inside human cavities but are now becoming the key instrument for the incisionless surgery known as natural orifice transluminal endoscopic surgery (NOTES). Since the current endoscope technology gives limited maneuverability, dexterity, and functionality, a number of new endoscope designs have been proposed. Due to miniaturization, conduit, and actuation simplicity, many of the new designs rely on cable-actuating mechanisms similar to the current technology. Basic kinematical and static analyses for this device have not appeared in the literature. In this paper the articulated section of a planar cable-driven endoscope is modeled as a serial robot. The kinematic and static analyses for single-jointed and multi-jointed endoscope structures are performed to relate tip motion to the controlling inputs. Pre-tensioning cables increases the endoscope stiffness and extends its range of operation.

Abstract:

Robot-assisted Minimally Invasive Surgery (MIS) and Natural Orifice Transluminal Endoscopic Surgery (NOTES) are commonly adopted in Gastro-Intestinal (GI) cancer treatment with Endoscopic Submucosal Dissection (ESD). While using fully flexible cable- driven robots brings benefits to patients such as lower rate of complications and shorter healing time, the engineering challenges, for example, size and stiffness, manufacturability and sensorless environment, limit functionalities of robotic instruments and surgery performance. The rolling feature, rotation along the wrist of the instrument, is a good-to-have feature for surgical procedures with orientational and positional requirements such as tractioning and suturing with graspers. In traditional laparoscopy, rolling can be achieved by rotating the long straight rod of the instruments, which is straightforward and effective. However, this is not commonly found in cable-driven endoscopic robotic systems due to mechanical limit for linear-to-rolling motion conversion at distal-end and unmodelled friction resisting torque transmission from proximal-end. Generally, researchers have three approaches to this problem. First, rotate the endoscope or overtube and the instrument together [1] [2]. However, this is not favorable to both surgeon and patient since rotating a twisted endoscope inside a patient’s body requires a large amount of torque and rubbing would create discomfort to the patient. Second, rotate the torque coil or backbone of the instrument [3] [4]. Because friction inside the endoscope is unpredicted and rotation is coupled with roll, pitch, and yaw motion, sophisticated modeling, shape/orientation sensing feedback may be required for robotic automation. Third, develop a distal mechanism to convert cable linear motion into axial rotation [5] [6]. With this method, the coupling problem is solved and power transmission efficiency is improved but a larger and more complicated design is required, and an extra-rigid segment is usually unavoidable. The performance depends greatly on design and implementation. This paper aims to demonstrate a scalable distal joint rotation mechanism for continuum endoscopic robots that can increase instrument dexterity and manipulability to ease the work of surgeons.

Abstract:

Natural orifice translumenal endoscopic surgery (NOTES) has reduced the invasiveness of surgery by eliminating external incisions on the patient. With this type of procedure, recovery time is drastically shortened, cosmetics are improved, and infections and pain are greatly reduced. For NOTES procedures to be successfully performed, a flexible endoscope or similar instrument is important for passing orifice flexures. However, technological deficiencies like poor angulations of surgical instruments introduced through working channels in flexible endoscopes, the lack of scope fixation, and lack of scope stiffening are technological barriers which prevent NOTES from being widely accepted in human surgeries. A novel multifunctional robot with an articulated drive mechanism for NOTES has been developed. The steerable articulating drive mechanism is connected to the robotic end effector to guide the robot and navigate through a natural orifice. The design process for the articulating drive mechanism and engineering analysis are discussed in this paper. Workspace of the drive mechanism with and without a translational insertion degree of freedom is presented in detail. The kinematics of the drive mechanism is also discussed. Additionally, friction in the spherical joints of the drive mechanism is explored to characterize its influence on the overall shape achieved by the articulation, including the effects of varying the total length in the steering mechanism. The surgeon control console for the drive mechanism is briefly discussed as well. Bench-top testing results are presented as proof of feasibility of the design.

Abstract:

Objective: Investigate the impact of diaphragm sellae competence on surgical outcomes and risk factors for postoperative hypothalamic injury (HI) in patients undergoing endoscopic transsphenoidal surgery (ETS) for infra-diaphragmatic craniopharyngiomas (ICs). Methods: A retrospective analysis of 54 consecutive patients (2016-2023) with ICs treated by ETS was conducted. All tumors originated from the sellar region inferior to the diaphragm sellae and were classified into two subtypes in terms of diaphragm sellae competence: IC with competent diaphragm sellae (IC-CDS) and IC with incompetent diaphragm sellae (IC-IDS). Clinical features, intraoperative findings, and follow-up data were compared between subtypes. Postoperative HI was assessed using a magnetic resonance imaging-based scoring system. Results: Fifty-four patients (29 males, 25 females) were included in this study, with 12 (22.2%) under 18 years old. Overall, 35 cases were IC-CDS, while 19 were IC-IDS. Compared with IC-CDS, patients with IC-IDS tended to have hormone hypofunction before surgery (p = 0.03). Tumor volume in IC-IDS group (9.0 ± 8.6 cm3) was also higher than that in IC-CDS group (3.3 ±3.4 cm, p = 0.011). Thirty-seven patients underwent standard endoscopic transsphenoidal approach (SEA) and 17 underwent an extended endoscopic transsphenoidal approach (EEA). Gross total resection (GTR) was achieved in 50 cases (92.6%). Postoperative CSF leak was observed in four patients (7.4%). Permanent diabetes insipidus (DI) occurred in 13 patients (27.7%), six in IC-CDS and seven in IC-IDS. Postoperative HI occurred in 38.9% of patients. Univariate analysis revealed that large tumor size (p = 0.014), prior hypopituitarism (p = 0.048) and IC-IDS (p < 0.001) were significantly associated with postoperative HI. Multivariate analysis revealed that IC- IDS was the sole predictor of postoperative HI. Conclusion: To our knowledge, this is the largest case series in the literature to describe IC resected by endoscopic surgery in a single institution. Classification based on diaphragm sellae competence highlights distinct clinical features and surgical outcomes between IC-CDS and IC-IDS subtypes. Notably, IC-IDS is an independent risk factor for postoperative HI. Preoperative identification of subtype can guide surgical strategy and potentially minimize complications.
