Comparative Evaluation of Laser System to Conventional Surgical Approaches in Periodontal Healing Using Optical Coherence Tomography

Background: Optical coherence tomography (OCT) is an emerging, radiation-free diagnostic tool in dentistry, providing high-resolution, real-time imaging of both hard and soft tissues, including periodontal areas, for more accurate postoperative evaluations. This study aims to investigate the efficacy of OCT on periodontal tissues in animals by comparing the healing effects of laser therapy with those of conventional surgical instruments. Methods: Six rabbits underwent periodontal surgery using a laser, scalpel, and punch to perform an apically positioned flap on the mandibular anterior incisors and to create a tongue ulcer on the dorsal surface of the tongue. Visual and OCT evaluations were conducted on days 1, 2, 3, 7, and 14. Results: In periodontal surgery, the laser exhibited slightly faster healing compared to other methods. In tongue ulcer formation, the scalpel and punch groups demonstrated slightly faster healing than that of the laser. However, both methods ultimately showed similar healing outcomes. Conclusions: In the dental field, OCT is emerging as a valuable tool for assessing healing, including early stages of healing, in periodontal therapy.

New approach for combined aortic valve and coronary procedures through the left anterior minithoracotomy.

We have developed a novel technique for accessing the aortic valve (AoV) through the left anterior minithoracotomy (LAmT). This approach has been used in patients requiring both AoV surgery and coronary artery bypass grafting (CABG). From April 2023 to July 2023, we performed 6 concomitant AoV procedures and CABG through the LAmT. The mean age was 71.5 [standard deviation (SD): 5.8; 64; 82] years, and the mean left ventricular ejection fraction was 53% (SD: 12.1; 30; 60). Surgical technique includes LAmT in the fourth intercostal space, peripheral cardiopulmonary bypass, aortic cross-clamping using transthoracic clamp, cold blood cardioplegia, conventional oblique aortotomy and special surgical exposure manoeuvres, aimed to position the ascending aorta and AoV close to the surgical incision. AoV was effectively visualized and the procedure was performed as planned in all 6 patients. No conversion to sternotomy was required. AoV replacement with biological prosthesis was performed in 6 (100%) patients. Conventional surgical instruments were used in all cases. The long-shafted instruments were not required. Knot-pusher was used in 4 (67%)cases. Concomitant complete revascularization was achieved in all cases. The mean number of distal anastomosis was 2.0 (SD: 0.6; 1; 3). Total operation time was 371 (SD: 43; 300; 420) min, cardiopulmonary bypass time was 253 (SD: 36; 193; 284) min and cross-clamp time was - 162 (SD: 29; 128; 214) min. intensive care unit stay was-1.5 (SD: 0.55; 1; 2) days, total hospital stay was-7.3 (SD: 1; 6; 9) days. There were no revisions for bleeding, no strokes or other major complications, and no hospital or 30-days mortality. The simultaneous performance of AoV replacement and multivessel CABG through a single left anterior thoracotomy is technically feasible and can be carried out by experienced surgeons. However, a larger number of cases are required to fully comprehend the potential limitations of this procedure.

Craniomaxillofacial Surgery with Computer-generated Three-dimensional Solid Models.

Restoring complex craniofacial deformities presents numerous challenges. Recent years have seen the development of new surgical techniques aimed at improving operation quality and reducing difficulty. However, designing the reduction volume for the affected region and achieving precise contouring remain difficult tasks. The use of three-dimensional (3D) solid models can provide significant assistance at all stages of the operations. This study aimed to investigate the validity of prototype 3D solid models for complex craniofacial operations. Simulated 3D models of the patients were used. Conventional surgical instruments were employed for the planning of the operations. Patients had follow-up periods ranging from 6 to 18 months. Operations have been planned and performed using three-dimensional solid models. Intraoperative steps were executed as simulated during planning. No major complications were developed. All bone and soft-tissue reconstructions healed without major infection. Stereolithographic models provide: 1) a better understanding of anatomy, 2) presurgical simulation, 3) intraoperative accuracy in lesion localization, 4) accurate fabrication of implants, and 5) improved education for trainees. An accurate method for intraoperative navigation and preoperative planning is clearly useful. This technology offers a direct representation of the patient's anatomy through computer reconstruction, allowing for the efficient and precise transfer of information in complex facial restorative procedures.

New approach to the mitral valve through the left anterior minithoracotomy for combined valve and coronary surgical procedures

ObjectiveWe have developed a new technique for accessing the mitral valve through the left anterior minithoracotomy. This approach has been used in patients requiring both mitral valve surgery and coronary artery bypass grafting. MethodsFrom October 2020 to September 2022, we performed 24 concomitant mitral valve procedures and coronary artery bypass grafting through the left anterior minithoracotomy. The average age of the patients was 65.5 years, and the mean left ventricular ejection fraction was 44.5%. Computed tomography angiography was routinely performed preoperatively. The surgical technique included a left anterior minithoracotomy in the fourth intercostal space, peripheral cardiopulmonary bypass, aortic crossclamping using a transthoracic clamp through the additional port in the left second intercostal space, the administration of cold blood cardioplegia, a right atrial transseptal approach to the mitral valve, and special surgical exposure maneuvers. These maneuvers were designed to displace the heart into the left pleural space by pulling the inferior vena cava tape and the ascending aorta tape to the left. Conventional mitral valve surgical techniques were used. The mitral valve repair or replacement was performed after the distal anastomoses to the right and circumflex coronary system were completed. Subsequently, after the mitral valve procedure, coronary anastomosis to the left anterior descending artery was performed. ResultsThe mitral valve was effectively visualized, and a planned procedure was successfully completed in all patients. There was no need for conversion to a sternotomy. mitral valve repair was performed in 22 patients (91.7%), and mitral valve replacement was performed in 2 patients (8.3%). Conventional surgical instruments were used in 10 cases (41%), and long-shafted instruments were used in 14 cases (59%). A knot-pusher was required in 9 cases (37.5%). A computed tomography distance from the skin level to the mitral valve posterior annulus of more than 14 cm was identified as a technical difficulty marker, necessitating the use of long-shafted instruments. Concomitant complete revascularization was achieved in all cases. The mean number of distal anastomoses was 2.54 ± 0.7 (1; 4). Total operation time was 341 ± 41 (285; 420) minutes, cardiopulmonary bypass time was 231 ± 38 (172; 316) minutes, and the crossclamp time was 127 ± 23 (80; 169) minutes. Patients had a mean intensive care unit stay of 1.87 ± 0.69 (1; 4) days, and their total hospital stay averaged 6.54 ± 1.86 (4; 10) days. There were no reoperations due to bleeding, no occurrences of strokes, and no other major complications. There were no instances of hospital mortality or mortality within 30 days after the procedures. ConclusionsMitral valve repair or replacement through the left anterior thoracotomy and transseptal approach is a valuable and effective technique that can be used for concomitant procedures performed through a single minithoracotomy incision in selected patients.

Hybrid Limited Shoulder Surgical Management (HLSSM) Sayed Issa's Hybrid Shoulder Arthroscopic-Open Surgical Management

Introduction The idea of HLSSM2 is to get the least easy surgical intervention, as arthroscopic surgery begins with examining the shoulder joint, and the location and size of the lesion are determined, then open over the lesion with an open surgical approach that is very limited for surgical repair; not using arthroscopic instruments but conventional surgical instruments in the second step. Figure 1 Methods Clinical experience with this technique consists of 44 cases over a period of thirty-one months, this study was from September 2020 to May 2023. All cases were done as outpatients and under general anesthesia. Results The mean duration of the operation was 35 minutes, and the minimum duration was 25 minutes. There was no major nerve or vascular injury in all cases. This technique is simple, safe, and good cosmetically satisfactory for all patients after full recovery about three months after the procedure, and it is cost-effective. One 43-year-old female patient suffered pain and stiffness during the first six months after surgery and was not very satisfied, she did not stop visiting us till now, she was not happy because of shoulder pain and tenderness. Conclusion It can be used by experienced hand surgeons in shoulder arthroscopy and in Mini Lateral Shoulder Approach (MLSA)3, especially in countries where shoulder arthroscopic release and repair with suture anchors are expensive4 or not available. This technique is not very simple but is available, safe, cosmetically satisfactory, and cost-effective.

Analysis of influence of surgical instruments on accuracy of magnetic navigation system for craniofacial surgery robots

IntroductionIn craniofacial surgery, magnetic navigation systems can effectively extend the doctor’s limited visual range, improve their surgical precision, shorten the operation time, and reduce the incidence of surgical complications. Owing to the ease of magnetic navigation, the accuracy of the magnetic navigation system is affected by various equipment in the operating room. Therefore, its large-scale application is lacking because the navigation accuracy requirement can be extremely high during craniofacial surgery. Therefore, the accuracy of magnetic navigation systems is crucial. Various surgical instruments have been evaluated to effectively reduce the interference of magnetic navigation systems with surgical instruments. In craniofacial surgery, magnetic navigation systems can effectively extend the doctor’s limited visual range, improve their surgical precision, shorten the operation time, and reduce the incidence of surgical complications. Owing to the ease of magnetic navigation, the accuracy of the magnetic navigation system is affected by various equipment in the operating room. Therefore, its large-scale application is lacking because the navigation accuracy requirement can be extremely high during craniofacial surgery. Therefore, the accuracy of magnetic navigation systems is crucial. Various surgical instruments have been evaluated to effectively reduce the interference of magnetic navigation systems with surgical instruments. In the surgical environment, the use of surgical instruments during mandibular surgery was simulated by selecting several conventional surgical instruments to record errors in the magnetic navigation system. The fluctuation values of the magnetic navigation errors were subsequently estimated and changes in its accuracy measured. MATLAB was used to calculate and analyze the fluctuations of the magnetic navigation errors. As results, the high-frequency electrosurgical system caused the greatest interference with the magnetic navigation system during surgery while powered on, with a maximum fluctuation error value of 1.8120 mm, and the maximum fluctuation error values of the stitch scissors, teeth forceps, and a needle holder were 1.3662, 1.3781, and 0.3912 mm, respectively. The closer the instrument is to the magnetic field generator or navigation target, the greater its impact. In conclusion, stitch scissors, teeth forceps, a needle holder, and the high-frequency electrosurgical system all affect magnetic navigation system accuracy. Therefore, it is necessary to avoid magnetic navigation system use and surgical instrument disturbances during surgery or select surgical instruments that do not interfere with the system. Surgical instruments must be evaluated for electromagnetic interference before they can be used in surgery with a magnetic navigation system.

Ultrasonic bone curette in thoracic spinal decompression: a comprehensive systematic review and meta-analysis.

The aim of this study was to compare the efficacy and safety of ultrasonic bone curette (UBC) and conventional surgical instruments in thoracic laminectomy decompression (TLD) for the treatment of thoracic spinal stenosis (TSS) by meta-analysis. Two authors independently searched Medline via PubMed, Embase, Cochrane Library, Web of Science, Wanfang Database, and China National Knowledge Infrastructure for the period from the establishment of the database until January 2023 to identify the studies on the safety and efficacy of UBC vs. conventional instruments for TSS. Data extraction and quality assessment were performed by two researchers independently. We used RevMan 5.4 software (Review Manager Web, The Cochrane Collaboration, Copenhagen, Denmark) to analyze the data. Eight retrospective studies were included in the present work. This meta-analysis revealed that no significant differences in the preoperative JOA scores, the JOA scores at the last follow-up, the improvement rate of JOA scores, and the incidence of cerebrospinal fluid leakage/dura injury were detected between the two groups (p>0.05). However, there were significant differences in the operative time and intraoperative blood loss during single-level TLD [operative time: MD=-1.47, 95% CI (-1.86, -1.09), p<0.001; intraoperative blood loss: MD=-46.62, 95% CI (-53.83, -39.40), p<0.001], total operative time [MD=-56.88, 95% CI (-69.66, -44.10), p<0.001], total intraoperative blood loss [MD=-143.52, 95% CI (-212.49, -74.54), p<0.001], the incidence of neurological deterioration/nerve root injury [RR= 0.29, 95% CI (0.09, 0.91), p=0.03] between the groups. The application of UBC in TLD to treat TSS is safe and effective. UBC can significantly shorten operation time and reduce intraoperative blood loss compared to traditional surgical instruments. Moreover, it has the advantage of reducing perioperative nerve injury.

5-Year Survivorship and Outcomes of Robotic-Arm-Assisted Medial Unicompartmental Knee Arthroplasty.

Purpose While unicompartmental knee arthroplasty (UKA) has demonstrated benefits over total knee arthroplasty (TKA) in selected populations, component placement continues to be challenging with conventional surgical instruments, resulting in higher early failure rates. Robotic-arm-assisted UKA (RA-UKA) has shown to be successful in component positioning through preop planning and intraop adjustability. The purpose of this study is to assess the 5-year clinical outcomes of medial RA-UKA. Methods This study was a retrospective review of a single-center prospectively maintained cohort of 133 patients (146 knees) indicated for medial UKA from 2009 to 2013. Perioperative data and 2- and 5-year Knee injury Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Score (WOMAC), and Forgotten Joint Score (FJS) outcome measures were collected. Five-year follow-up was recorded in 119 patients (131 knees). Results Mean follow-up was 5.1 ± 0.2 years. Mean age and BMI were 68.0 ± 8.1 years and 29.3 ± 4.7 kg/m2, respectively. At 2-year follow-up, mean KOOS, WOMAC, and FJS were 71.5 ± 15.3, 14.3 ± 7.9, and 79.1 ± 25.8, respectively. At 5-year follow-up, mean KOOS, WOMAC, and FJS were 71.6 ± 15.2, 14.2 ± 7.9, and 80.9 ± 25.1, respectively. Mean change in KOOS and WOMAC was 34.6 ± 21.4 and 11.0 ± 13.6, respectively (p < 0.001 and p < 0.001). For patient satisfaction at last follow-up, 89% of patients were very satisfied/satisfied and 5% were dissatisfied. For patient activity expectations at last follow-up, 85% met activity expectations, 52% were more active than before, 25% have the same level of activity, 23% were less active than before, and 89% were walking without support. All patients returned to driving after surgery at a mean 15.2 ± 9.4 days. Survivorship was 95% (95% CI 0.91-0.98) at 5 years. One knee (1%) had a patellofemoral revision, two knees (1.3%) were revised to different partial knee replacements, and five knees (3.4%) were converted to TKA. Conclusion Overall, medial RA-UKA demonstrated improved patient-recorded outcomes, high patient satisfaction, met expectations, and excellent functional recovery. Midterm survivorship was excellent. Longitudinal follow-up is needed to evaluate long-term outcomes of robotic-arm-assisted UKA procedures.

A novel arthroscopic pre-curved cannula with both flexibility and high stiffness.

Curved surgical instruments are being developed to expand the workspace of straight surgical instruments. They are required to have a small diameter and high stiffness. We developed a double-spring pre-curved cannula (DSPC) for electrocauterization, which has curved movements controlled solely by translational motion, and high stiffness via wire tension. It comprises a straight extension spring, pre-curved flat spring and braided high-modulus polyethylene line. A handheld device was designed for intuitive DSPC manipulation. The cannula has a 3.9mm diameter and serves as a protective tube such that the electrode can safely reach the lesion. Experimental results demonstrate that the DSPC has ideal curvature and maximum stiffness of 1.38N/mm. In a cadaveric study, the DSPC reached the inferior glenohumeral ligament, which conventional surgical instruments cannot access, and surgeons successfully performed electrocauterization. The designed DSPC is effective for future use in forceps, curettes and surgical robots.

The fragmented resection of tumors are inherent defects of traditional TURBT. The objective of this study was to explore a safe and effective method of TURBT. We performed a novel transurethral bladder tumor resection under air cystoscope. Since the depth of resection is limitless under pneumocystoscope, and there is no previous report, we named this novel operation as “Super Transurethral Resection of Bladder Tumor” (STURBT). METHODS: The operation was performed under general or epidural anesthesia. The Super Scope (S-Scope) was inserted through the urethra, and the bladder was filled with carbon dioxide, and the pressure was set as 12 mmHg. The novel S-Scope has a channel to accommodate conventional laparoscopic surgical instruments, such as supersonic scalpel, bipolar scissors, forceps, and suctions. First the normal bladder mucosa 1 cm from the tumor was marked with a supersonic scalpel. Blunt separation and sharp resection were performed from periphery to the central base of the tumor to achieve en bloc resection. The β basket, a bladder tumor retrieving device, was inserted through the channel, and the tumor was removed in whole or by dividing into 2 to 3 parts. The urethral stent was placed, and the bladder was flushed with normal saline. RESULTS: 5 patients underwent STURBT, and 6 tumors were resected with the largest diameter of 3∼5cm. The average resection time was 28±16.4 minutes, and the tumor was retrieved en bloc or sub-en bloc. There was no obturator nerve reflex or bleeding during operation. Pathological diagnosis showed 1 case of pheochromocytoma and 4 cases of high grade urothelial carcinoma with stage T1∼T2a. Bladder muscle layer was visible in all cases. 3 cases of bladder cancer with muscle invasion received adjuvant intravenous chemotherapy. 4 cases with high grade urothelial carcinoma also received intravesical irragation of BCG periodically. Cystoscopy 3 months post-operation showed well healing of the bladder. There was no tumor recurrence during a mean follow-up of 11.8 (3-18) months. CONCLUSIONS: STURBT is a novel surgical method to treat bladder tumor, which has several advantages over traditional TURBT. No fluid irrigation was needed, and no urine extravasation developed. The supersonic scalpel will not stimulate the obturator nerve. The en bloc tumor resection decreased tumor dissemination and an accurate pathological TNM stage could be obtained. S-Scope assisted STURBT could make full use of the current laparoscopic surgical instruments, which had obvious advantages in transurethral treatment of bladder tumors.

Conventional aortic valve replacement versus transcatheter aortic valve implantation: professional requirements for nurses.

At present, the recommendation grade of transcatheter aortic valve implantation (TAVI) for aortic valve stenosis (AVS) has increased in many guidelines. Establishing an optimized TAVI nurse team is essential for improving surgical quality and outcomes. We compared the professional requirements for nurses in two surgical approaches for aortic stenosis and the different roles of nurses in the surgical teams, with an attempt to further improve the training programs for specialized nurses. The required professional knowledge and the role of nursing staff during TAVI or AVR (Conventional aortic valve replacement) were analyzed. These included knowledge on the pathophysiology of aortic stenosis, advantages and disadvantages of different heart valves, extracorporeal circulation, nursing cooperation during valve replacement, conventional surgical instruments and interventional consumables, surgical complications, radiation protection, operation of pacemakers, theory and operation of electric defibrillation. And the surgical team members and their roles, and doctor-patient satisfaction were also compared. TAVI had higher requirements for the basic knowledge of the pathophysiology of aortic stenosis, advantages and disadvantages of different heart valves, extracorporeal circulation and theory and operation of electric defibrillation. And the clinical professional knowledge of conventional surgical instruments and interventional consumables, surgical complications, radiation protection, nursing cooperation, operation of pacemakers were also higher required in TAVI. Doctor-patient overall satisfaction were higher in TAVI than AVR (95.8% vs. 84.4%, 97.5% vs. 92.7%). The professional requirements for nurses differs between TAVI and AVR. Comprehensive programs should be designed to develop the basic knowledge and professional training for future cardiac operation.

Usefulness of articulating laparoscopic instruments during laparoscopic gastrectomy for gastric adenocarcinoma.

PurposeConventional straight-shaped laparoscopic surgical instruments have limitations that, unlike robotic surgery, the wrist joint cannot be used. This study aimed to analyze the short-term safety and feasibility of ArtiSential (Livsmed), a new articulating laparoscopic instrument, which obviates the limitations of conventional laparoscopic surgery and allows the wrist joint to be used freely over 360° as in robotic surgery.MethodsThe study included patients who underwent conventional laparoscopy or laparoscopy with the ArtiSential instrument. Patients who underwent laparoscopic gastrectomy for primary gastric adenocarcinoma in our institution were retrospectively reviewed. The groups were propensity score matched in a 11 ratio. Primary endpoint was incidence of early postoperative complication (postoperative 30-day morbidity and mortality) and secondary endpoints were operative outcomes.ResultsA total of 327 patients (147 of the conventional group and 180 of the ArtiSential group) were propensity score matched. After propensity score matching was performed, each group comprised of 122 patients. Both groups were comparable with regard to operation time, estimated blood loss, number of retrieved lymph nodes, and length of hospital stay. The ArtiSential group had a faster time to a fluid diet (2.6 ± 1.3 days vs. 2.3 ± 0.6 days, p = 0.015). There was no statistically significant difference in early postoperative complications between the two groups (the conventional group, 23.0%; the ArtiSential group, 26.2%; p = 0.656).ConclusionThe current study showed that the use of ArtiSential is a safe and feasible option without increasing operation time, length of hospital stay, and intraoperative bleeding.

A Cooperative Human-Robot Interface for Constrained Manipulation in Robot-Assisted Endonasal Surgery

Endoscopic endonasal surgery (EES) is a minimally invasive technique for removal of pituitary adenomas or cysts at the skull base. This approach can reduce the invasiveness and recovery time compared to traditional open surgery techniques. However, it represents challenges to surgeons because of the constrained workspace imposed by the nasal cavity and the lack of dexterity with conventional surgical instruments. While robotic surgical systems have been previously proposed for EES, issues concerned with proper interface design still remain. In this paper, we present a cooperative, compact, and versatile bimanual human-robot interface aimed to provide intuitive and safe operation in robot-assisted EES. The proposed interface is attached to a robot arm and holds a multi-degree-of-freedom (DOF) articulated forceps. In order to design the required functionalities in EES, we consider a simplified surgical task scenario, with four basic instrument operations such as positioning, insertion, manipulation, and extraction. The proposed cooperative strategy is based on the combination of force based robot control for tool positioning, a virtual remote-center-of-motion (VRCM) during insertion/extraction tasks, and the use of a serial-link interface for precise and simultaneous control of the position and the orientation of the forceps tip. Virtual workspace constraints and motion scaling are added to provide safe and smooth control of our robotic surgical system. We evaluate the performance and usability of our system considering reachability, object manipulability, and surgical dexterity in an anatomically realistic human head phantom compared to the use of conventional surgical instruments. The results demonstrate that the proposed system can improve the precision, smoothness and safety of the forceps operation during an EES.

Biportal endoscopic spine surgery (BESS): considering merits and pitfalls.

The biportal endoscopic spine surgery allow us to use conventional spine surgical instruments in the endoscopic procedure like open surgery. And protection of the neural structures with assistant retractor make this procedure safer than the uniportal endoscopic spine surgery. The authors present a novel technique in treating degenerative spinal diseases in variable access angle different from the conventional uniportal endoscopic spine surgeries. The main objective of this report is presenting two approaches for central and extraforaminal stenosis using an assistant retractor. Both central and foraminal stenosis were well decompressed and a migrated disc fragment was removed successfully with this minimal endoscopic procedure without major complications in these cases.

Using of piezoelectric surgical instruments in oral and maxillofacial surgery

Piezoelectric surgery is a relatively new technique that provides safe and effective osteotomies using piezoelectric ultrasonic vibrations, and every day new devices with new features are produced and marketed. Piezosurgery instruments have superior properties compared to conventional rotary surgical instruments. Because of its micrometric and selective cutting, the piezoelectric surgery device provides a safe and sensitive osteotomy without causing necrotic damage to the bone. Compared to conventional rotary instruments, the most important feature is that it works only on mineralized tissues while maintaining soft tissue and blood support. It does not damage the tissues in contact with soft tissues such as the bone and mucous membranes in and around the operation area. In this study, properties, usage areas, advantages and disadvantages of piezoelectric surgical instruments which are frequently preferred in Oral, Dental and Maxillofacial Surgery applications as in many fields of orthopedics and brain surgery of medicine are explained.

The Evaluation of Laser Application in Surgery: A Review Article.

There are several types of surgeries which use lasers in the operating room. Surgeons use lasers in general surgery or surgical specialties to cut, coagulate, and remove tissue. In modern medicine, the application of laser therapy is an attractive subject due to its minimal invasive effect. Today lasers are widely used in the treatment and diagnosis of many diseases such as various cancers, lithotripsy, ophthalmology, as well as dermatology and beauty procedures. Depending on the type of lasers, the wavelength and the delivery system, most lasers have replaced conventional surgical instruments for better wound healing results. Over time, by using many different tools and devices, new lasers have been created; as a result, they are used in a wide range of medical special cases. In this review, laser applications in surgery and its beneficial effects compared to previous surgeries with the aim of providing appropriate therapeutic and non-invasive solutions with minimal side effects after surgery are investigated.

Video Objective To describe and demonstrate the feasibility and safety of robotic laparoendoscopic single-site radical hysterectomy and pelvic lymphadenectomy with conventional robotic surgical instruments. Setting A university hospital. Interventions Robotic laparoendoscopic single-site radical hysterectomy and pelvic lymphadenectomy with conventional robotic surgical instruments. All of the interventions were performed using a da Vinci Si surgical system and all the surgery instrument was conventional robotic instruments. A uterine manipulator and an indwelling catheter (Foley catheter) were used. The patient was in the Trendelenburg position, and the robot was placed between her legs. By adopting the principle of the chopstick technique for R-LESS, a 30° robotic lens was placed in the upward configuration to reduce collision and achieve a better view. Conclusion Our preliminary experience has demonstrated that with experienced laparoscopic skills, R-LESS with the da Vinci Si system is a feasible and safe surgical approach for performance of radical hysterectomy and pelvic lymphadenectomy with conventional robotic surgical instruments. Further studies with greater number of patients in multiple settings will help us to fully elucidate the role of da Vinci Si surgical system in single-site gynecologic surgery.

Application value of dual channel dual curved endoscope in the endoscopic submucosal dissection for gastric angle mucosal lesions

Objective: To evaluate the clinical value of dual channel dual curved endoscope in the endoscopic submucosal dissection (ESD) for gastric angle mucosal lesions. Methods: A descriptive cohort study was carried out. Clinicopathological data of 20 cases with gastric angle mucosal lesions undergoing ESD by dual channel dual curved endoscope in our center from October 2016 to August 2018 were collected and analyzed retrospectively. Inclusion criteria: (1) the lesion was located in the gastric angle confirmed by gastroscopy before ESD. (2) CT examination showed no distant metastasis. (3) pathological biopsy confirmed precancerous lesion or early cancerous lesion without submucosal invasion. (4) the whole operation was performed by the same endoscopist with ESD experience of about 2000 cases. Patients with previous ESD history of gastric angle and other serious diseases were excluded. The dual channel dual curved endoscopy (Olympus, GIF-2TQ260M) and other conventional endoscopic surgical instruments were used in all the cases. Complete tumor resection rate, pathological results, intraoperative and postoperative complications, operation time and hospitalization time were observed. Follow - up parameters included residual tumor, local recurrence and heterogeneous lesion. Results: Of 20 patients, 14 were male and 6 were female with an average of 55.6 years (range, 37 to 75). All the tumors located in gastric angle. Specimen size ranged from 1.2 to 5.5 (average 2.9) cm. Operation time ranged from 50 to 120 (average 85.8) minutes. Hospital stay ranged from 3 to 7 (average 5.1) days. The en bloc excision was performed successfully in all 20 cases. There was no perforation or bleeding during or after operation. Pathological results showed curative or nearly curative resection stage in all the cases. No tumor residual or recurrence was found during follow-up for 8 to 30 (average 18.5) months. Conclusion: Dual channel dual curved endoscope can provide good vision and easy control in removing the lesion completely and avoiding complications during the ESD procedure in gastric angle mucosal lesions with good long-term efficacy.
