Project description:The popularity of endoscopes has been expanding not only in diagnostics but also in therapeutics. The traditional septal surgery also has come under the purview of endoscopic surgery in the last few decades. Endoscopic septoplasty has definitely many advantages over the conventional procedure. But the only disadvantage of endoscopic surgery is that it is a single handed technique as the other hand is used for holding the endoscope which may compromise the overall surgical time as the hemostasis and suctioning of the surgical field off the blood cannot be done simultaneously, in addition to the surgeon fatigue associated with holding the endoscope in the left hand. Endoscope holder allows both hands of the surgeon to be free for surgical manipulation and also imitates more or less same actions of the left hand. To report the preliminary use of Khan's endoscope holder for endoscopic septoplasty. Prospective Non Randomized Clinical Study. Khan's Endoscope Holder, which was primarily designed for endoscopic ear surgery, has been used for two handed technique of endoscopic septoplasty. The design of the Endoscope holder is described in detail. A total of 49 endoholder assisted endoscopic septoplasties were operated from Nov 2014 to Jan 2015 in MIMER Medical College and Sushrut ENT Hospital, Talegaon D, Pune, India. Our Endoscope Holder is a good option for two handed technique in Endoscopic Septoplasty due to its advantages. The study reports the successful usage and applicability of the endo holder for endoscopic Septoplasty. Level of evidence IV.

Project description:UnlabelledThe well established techniques in tympanoplasty are routinely performed with operating microscopes for many decades now. Endoscopic ear surgeries provide minimally invasive approach to the middle ear and evolving new science in the field of otology. The disadvantage of endoscopic ear surgeries is that it is one-handed surgical technique as the non-dominant left hand of the surgeon is utilized for holding and manipulating the endoscope. This necessitated the need for development of the endoscope holder which would allow both hands of surgeon to be free for surgical manipulation and also allow alternate use of microscope during tympanoplasty. To report the preliminary utility of our designed and developed endoscope holder attachment gripping to microscope for two handed technique of endoscopic tympanoplasty. Prospective Non Randomized Clinical Study. Our endoscope holder attachment for microscope was designed and developed to aid in endoscopic ear surgery and to overcome the disadvantage of single handed endoscopic surgery. It was tested for endoscopic Tympanoplasty. The design of the endoscope holder attachment is described in detail along with its manipulation and manoeuvreing. A total of 78 endoholder assisted type 1 endoscopic cartilage tympanoplasties were operated to evaluate its feasibility for the two handed technique and to evaluate the results of endoscopic type 1 cartilage tympanoplasty. In early follow up period ranging from 6 to 20 months, the graft uptake was seen in 76 ears with one residual perforation and 1 recurrent perforations giving a success rate of 97.435 %. Our endocsope holder attachment for gripping microscope is a good option for two handed technique in endoscopic type 1 cartilage tympanoplasty. The study reports the successful application and use of our endoscope holder attachment for gripping microscope in two handed technique of endoscopic type 1 cartilage tympanoplasty and comparable results with microscopic techniques.Level of evidenceIV.

Project description:The tympanic membrane retraction pocket is a pathological invagination of tympanic membrane into the middle ear space. The most common sites for formation of retraction pocket are pars flaccida and postero-superior parts. Decision about the procedure and the timing of the treatment of retraction pockets is debatable and depends on the functional and anatomic condition of the ear. To evaluate the results of the technique of two handed endoscopic management of retraction pockets with sliced tragal cartilage. Prospective Non Randomized Clinical Study. The study included 41 ears operated with the technique of two handed endoscopic cartilage tympanoplasty for retraction pockets with endoscope holders from November 2013 to May 2016 with a follow up period ranging from 22 to 53 months. Cases of cholesteatoma and tympanic membrane perforation were excluded from the study. Pre and postoperative symptoms and air-bone gaps were recorded. The average preoperative air-bone gap in the study group was 24.53?±?4.326 dB. 28 ears were of pars tensa retractions (stage II-4, stage III-15, and stage IV-9) and 13 were pars flaccida retractions (stage III-8 and stage IV-5). 24 ears had ossicular erosion. The follow up revealed that, the results of two handed endoscopic sliced cartilage tympanoplasty for retraction pockets were stable and there was no recurrence of the retraction and the post-operative air-bone-gap closure was achieved to 13.62?±?4.78, 14.13?±?5.91 dB, 14.32?±?3.46 and 14.57?±?3.88 dB at 6 months, 1?year, 2?years, 3?years respectively. Though, indications for surgery are based mostly on anatomic status and observation of behaviour of retraction pocket over time, we recommend early management of retraction pockets by the technique of endoscopic sliced tragal cartilage tympanoplasty with tragal cartilage of 0.5 mm thickness using endoscope holder. Level of Evidence: Level 4.

Project description:Endoscopic surgeries have gained popularity not only in ENT but also in other surgical faculties. Endoscopic approach for sinus surgeries and otologic surgeries is well known. However, the major disadvantage of endoscopic aided surgeries as against microscope aided surgeries is thought to be the effective reduction in the working hands as the non-dominant hand of the surgeon is utilized for holding the endoscope. This urged the need for development of the endoscopic holder so as to allow both the hands of the surgeon for surgical manipulation.

Project description:Background: Transoral thyroid surgery represented by the da Vinci system is attracted attention and performed by several institutions. However, the current available da Vinci system still has some limitations to be improved for transoral thyroid surgery including high cost of equipment and expendables, larger diameter scope and instruments and no tactile sensation. It triggered us interest in more easily available robotic scope holder. Soloassist II (AktorMed GmbH, Barbing, Germany) is an active endoscope holder system which is controlled by a joystick. It has total six joints: three joints which are controlled by computer, one is controlled by manual and two act as a gimbal joint following the movement of the main body.Materials and methodsWe tried transoral endoscopic thyroidectomy using Soloassist II (AktorMed GmbH, Barbing, Germany) in December 2017 in our hospital.ResultsWe successfully performed four thyroid lobectomies in four patients with Soloassist II. We refined and described surgical procedures in each step using video clips. It provided an excellent vibration-free stable surgical view which enabled fatigue-free work, without shaking or tilting the horizon. The surgeon could perform transoral endoscopic thyroid surgery with only one assistant surgeon. Docking and preparation time for Soloassist was within 10 min in all four patients. The setup and dismantling could be performed parallel to the usual workflow. No complication was reported by any patient.Conclusions: The robotic scope holder (Soloassist II) seems to be safe and feasible equipment for performing transoral endoscopic thyroid surgery. Several possible advantages could be expected with this robotic scope holder.

Project description:BackgroundInnovations in surgical instruments have made single-port surgery more widely accepted and lead to a reduced demand for surgical assistants. As COVID-19 has ravaged the world, maintaining minimum medical staffing requirements and proper social distancing have become major topics of interest. We sought to evaluate the feasibility of applying the unisurgeon approach in single-port video-assisted thoracoscopic surgery aided by a robotic camera holder.MethodsOperative time, blood loss, setup time, postoperative hospital stays, and the number of participating surgeons in single-port video-assisted thoracoscopic lung resections were gathered for investigation after the introduction of the ENDOFIXexo robotic endoscope holder system. In this cohort, we collected 213 patients who underwent single port video thoracoscope surgery, including 57 patients underwent robotic endoscope arm assisted surgery and case-matched 52 patients in the robotic arm-assisted group with patients in the human-assisted group through propensity score-matched analysis.ResultsIn wedge resection, a single surgeon was able to completely operate on all lobes of target lesions. However, for anatomical resections, namely segmentectomy, the success rate was 95%, and for lobectomy, the success rate was only 64%. No significant differences between setup times, blood loss, or operative times between the two groups were observed.ConclusionsWhen an experienced uniport surgeon is assisted by a robotic endoscope holder, wedge resection is the most suitable procedure to be performed through unisurgeon single-port video-assisted thoracoscopic surgery without increasing setup time, operative time, or short-term complications. Verification of the technique's applicability for use in anatomic resections requires further investigation.

Project description:BackgroundFew studies have compared robotic-arm-assisted unisurgeon uniportal surgeries with conventional human-assisted uniportal video-assisted thoracoscopic surgeries (VATSs) in terms of surgical efficacy and patient safety. In the present study, we compared the aforementioned surgeries.MethodsWe explored two robotic endoscope holders-a passive robotic platform (ENDOFIXexo, EA group) and a pedal-controlled active robotic platform (MTG-100, MA group)-for unisurgeon uniportal surgeries and compared the surgical outcomes with those of human-assisted uniportal surgeries (HA group) in 228 patients with a lung lesion (size, <5 cm). The primary parameters for this comparison were surgical efficacy, patient safety, and short-term patient outcomes.ResultsNo significant differences were observed among the EA, MA, and HA groups. The success rate of robotic-arm-assisted unisurgeon uniportal wedge resection was 100%, regardless of the group. No major differences were noted in preparation time between the EA and MA groups. Segmentectomy was more favorable in the EA group than in the MA group. The rates of surgical conversion were 5% and 60% in the EA and MA groups, respectively. The EA and MA groups did not differ considerably from the HA group in terms of postoperative complications.ConclusionsUnisurgeon uniportal wedge resection may be effectively performed using a robotic endoscope holder, without the need for any human assistants with an expert hand. However, the rate of surgical conversion increases with the complexity of uniportal anatomic resections. The passive platform appears to be more suitable for unisurgeon uniportal surgery than the active pedal-controlled platform given the equipment in contemporary operating rooms.

Project description:ObjectiveTo observe and summarize variations of the chorda tympani nerve to effectively protect it during surgery.MethodsSurgical videos of patients undergoing endoscopic ear surgery in the past 3 years were retrospectively observed to identify chorda tympani nerve variations.ResultsIn total, 237 cases were reviewed. The tympanic sulcus or annulus was the boundary between the posterior wall of the external auditory canal and chordal eminence (CE). The chorda tympani nerve was divided into three types: type I, the periannular segment was located medial to the CE and covered by the bony eminence (32.5%); type II, the periannular segment was located inferior to the CE, and the nerve did or did not contact the bony edge of the CE (62.0%); and type III, the periannular segment was located lateral to the CE and medial to the tympanic annulus, and the iter chorda posterius was located in the tympanic sulcus (5.5%). The rate of injury to the chorda tympani nerve was 2.5% of 237 cases. The location of the iter chorda posterius on preoperative computed tomography was highly reliable for prediction of type I and III nerves. Secondary exposure of the posterior canaliculus might occur in patients with external auditory canal cholesteatoma, who were specifically included in this study.ConclusionCE-based classification of the chorda tympani nerve can concisely describe variations of the chorda tympani nerve and provide guidance for neuroprotection during endoscopic ear surgery. Patients with external auditory canal cholesteatoma may have secondary exposure of the posterior canaliculus.Level of evidenceNA.
