Abstract
Background: The transoral endoscopic approach to the central neck has rapidly become one of the most widely utilized remote-access approaches for thyroid and parathyroid surgery in the world. The approach involves three small incisions inside the lower lip and has an optimal cosmetic outcome with no visible scar. However, the technique is quite difficult and poses several challenges that limit its widespread adoption. To overcome these issues, a novel lateral vestibular approach (LaVA) was explored in cadavers. Methods: Study using 7 fresh human cadavers that were dissected using open and endoscopic techniques to explore the feasibility of a transoral vestibular approach to the central neck without gas insufflation. Results: This novel approach resulted in wide access to the central neck and allowed for a total thyroidectomy and central neck dissection while preserving the marginal mandibular and mental nerves. Conclusions: LaVA permits excellent access to the central neck with a wide working space without the need for gas insufflation and overcomes many of the limitations of current transoral endoscopic approaches to the central neck.

Abstract
BACKGROUND Transoral endoscopic vestibular approach (TOEVA) for thyroidectomy (TOETVA) and parathyroidectomy (TOEPVA) is gaining popularity, yet knowledge is based on a limited number of studies, mostly performed by surgeons experienced in laparoscopic\robotic surgery. METHODS All patients who underwent TOEVA at our institution between February 2018 and October 2019 were followed prospectively. Main outcomes were ability to accomplish surgery endoscopically (failure defined as conversion to open approach) and complications. RESULTS Seventy-one patients (52 TOETVA and 19 TOEPVA) were included. 98% (51/52) and 100% (19/19) of TOETVA and TOEPVA surgeries were accomplished endoscopically, respectively. Transient vocal cord and mental nerve injuries rates were 8.4% (6/71) and 2.8% (2/71), respectively. Thyroid carcinoma was diagnosed in 27 patients (51.9%), all completely excised with clean margins. CONCLUSIONS Adoption of the TOEVA suggested framework by head and neck surgeons without prior experience in laparoscopic/robotic techniques is feasible resulting in nearly 100% of surgeries accomplished endoscopically.

Laryngeal Mid-Cord Erythroleukoplakias: How to Modulate the Transoral CO 2 Laser Excisional Biopsy. Cancers (Basel) 2020; 12:cancers12082165. [PMID: 32759787 PMCID: PMC7464010 DOI: 10.3390/cancers12082165] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 07/29/2020] [Accepted: 07/30/2020] [Indexed: 12/17/2022] Open
Abstract
Background: The endoscopic appearance of glottic erythroleukoplakias is non-predictive of their histopathology, potentially ranging from keratosis to invasive squamous cell carcinoma (SCC). The aim of this study was to assess a comprehensive workup for the one-step diagnosis and treatment of mid-cord erythroleukoplakias, using CO2 laser excisional biopsy. Methods: We evaluated 147 untreated patients affected by 155 mid-cord erythroleukoplakias submitted to excisional biopsy by subepithelial (Type I) or subligamental cordectomy (Type II), across two academic institutions. Patients were evaluated by preoperative videolaryngostroboscopy, pre- and intraoperative videoendoscopy with biologic endoscopy (narrow band imaging, NBI, or the Storz professional image enhancement system, SPIES), either with or without intraoperative saline infusion into the Reinke’s space. Adequacy of treatment was the primary outcome. Results: The histopathologic diagnosis was keratosis in 26 (17%) cases, squamous intraepithelial neoplasia (SIN1-2) in 47 (30%), carcinoma in situ in 21 (14%), and SCC in 61 (39%) patients. The adequacy of treatment across the entire cohort was 89%. The intraoperative saline infusion procedure, facing not clearly suspicious lesions, raised the adequacy of treatment from 60% to 90% (p = 0.006). Conclusions: Excisional biopsy by Type I–II cordectomies, after a comprehensive diagnostic workup, should be accepted as an adequate and cost-effective treatment of unilateral mid-cord glottic erythroleukoplakias.

Abstract
OBJECTIVES/HYPOTHESIS To investigate the surgical, oncological, and functional outcomes of transoral robotic surgery (TORS) for the treatment of supraglottic squamous cell carcinoma. STUDY DESIGN Retrospective chart review. METHODS The charts of patients treated by TORS supraglottic laryngectomy (SGL) in an academic medical center were reviewed. The following outcomes were studied according to the tumor location: average robotic setup and operative times, mean estimated blood loss, postoperative complications, need of tracheotomy, refeeding characteristics, mean hospital stay, need of neck dissection and adjuvant therapy, 5-year local and regional controls, overall survival (OS), and disease-free survival (DFS). RESULTS Seventy-five patients underwent TORS SGL. Tumors were classified as cT1 (32%), cT2 (52%), and cT3 (16%). Average robotic setup and operative times and the mean estimated blood loss were 15 minutes, 55 minutes, and 20 mL, respectively. The mean follow-up period ranged from 2 to 5 years. The 5-year OS and DFS were 80.2% and 94.3%, respectively. Overall, 34.6% of patients received adjuvant radiotherapy. The majority of patients (92%) restarted an oral diet within 24 to 48 hours postsurgery. Transient tracheotomy was performed in 8% of patients. Postoperative hemorrhages occurred in 12 patients (16.0%), lengthening the hospital stay (mean = 6.8 days). There were no outcome differences regarding the tumor location. CONCLUSIONS TORS is an effective and safe therapeutic approach for early- and intermediate-stages cancers. Oncological outcomes may be quite similar to other surgical approaches, including transoral laser and open surgeries. Future randomized controlled studies are needed for comparing TORS SGL with other surgical procedures. LEVEL OF EVIDENCE 4 Laryngoscope, 131:1060-1065, 2021.

Abstract
Head and neck cancers are the most common cancers in the body. Treatments are determined on the basis of the location and stage of the primary tumor. The goal of treatment is to eliminate the tumor, prevent recurrence or metastasis, and maintain the quality of life. There are several treatments available for the management of head and neck cancers, including surgery, radiation therapy, chemotherapy, new molecular agents, and a combination of them. Transoral robotic technique is a short-time operation using a type of robotic machine in which the patient undergoes anesthesia for a shorter time and the side effects of this operation and the time of hospitalization are less than open surgery. Due to the importance of speed and accuracy in head and neck cancer surgery and the importance of application of robotics in surgery, the present study was designed and implemented to review the application of robotics in the management of head and neck cancers. In this review study, the keywords: application, robotic, surgical, head cancer, transoral robotic surgery (TORS), and neck cancer, were searched in ISI, PubMed, Scopus, Google scholar databases. Related articles written domestically or abroad that have covered areas such as the background of transoral robotic surgery, maintaining organ function and approaches, the advantages and disadvantages of TORS, the affordability of TORS, the combination of TORS with other therapeutic approaches published from 2003 to 2019 were reviewed. The use of robotic surgery for precise operations such as head and neck cancers seems to be essential. More advanced robotic devices are expected to expand the surgery treatment for head and neck cancers as well as the results of using TORS for oncologic optimization and acceptability of results while maintaining organ function and patient's quality of life.

Abstract
OBJECTIVE Thyroglossal duct cysts (TGDCs) are relatively common congenital midline neck masses that are treated with surgical excision. Traditionally these are removed along with any associated tract and the central portion of the hyoid bone through an anterior neck incision. Some patients with TGDCs want to avoid an external neck scar. METHODS We describe the details of a transoral endoscopic vestibular excision of a TGDC and the associated hyoid bone in an adolescent patient. RESULTS This novel approach was successful and there were no complications. CONCLUSION We propose that cervical TGDCs can be safely and completely removed with this approach in appropriately selected patients while avoiding a neck scar.

Abstract
Introduction: Conventional transoral robotic thyroidectomy (TORT) requires an axillary incision and additional flap dissection. This study aimed to outline the first ever experiences with TORT using three ports without axillary incision and compare the results between three-port and four-port TORT. Materials and Methods: A total of 100 consecutive patients were enrolled. The study sample comprised 47 patients who underwent four-port TORT from November 2016 to June 2017, and 53 patients who underwent three-port TORT from September 2018 to June 2019. The indication of the three-port TORT was the anterior/posterior length of the thyroid <1.8 cm and mass size <1.5 cm. Results: Operative time (minutes) was shorter in the three-port group (166.3 ± 35.4 versus 138.5 ± 34.4, P = .005). Hospital stay (days) was also shorter in the three-port group (3.8 ± 0.4 versus 2.4 ± 0.6, P = .003). TORT using three ports yielded a higher cosmetic satisfaction (3.68 ± 0.52 versus 3.89 ± 0.30, P = .002). Postoperative complications, level of calcium, parathyroid hormone, and pain were not significantly different between the groups. Conclusions: Our study showed that three-port TORT was associated with a shorter operative time, hospital stay, and excellent cosmesis than the conventional four-port option. In conclusion, TORT using three ports is a comparable and an effective operation method as a real scarless operation.

Abstract
Introduction A transoral (TO) vestibular approach is a new remote access approach to avoid cutaneous scars in an endoscopic thyroidectomy (ET). And transoral endoscopic thyroidectomy (TOET) has been widely used in papillary thyroid microcarcinomas (PTMCs). Aim To evaluate and compare endoscopic thyroidectomies with central neck dissection using a bilateral areolar (BA) approach and TO approach in patients with unilateral PTMCs. Material and methods In total, 92 papillary thyroid cancer (PTC) patients undergoing an endoscopic unilateral thyroidectomy with central neck dissection via a TO (n = 48) or BA (n = 44) approach were retrospectively enrolled from August 2017 to December 2018. Differences in various factors, such as clinical characteristics, surgery-related parameters, including operative complications, and hospital durations and costs, were compared. Results No significant between-group differences in the age and sex of the patients or the side, body mass index, total operative time, operative bleeding, superior parathyroid preservation in situ, operative complications, and postoperative day of discharge were found (all p > 0.05). The mean central neck dissection time, amount of postoperative drainage, extubation time, and inferior parathyroid preservation in situ were lower in the TO group as compared with these parameters in the BA group (all p < 0.05). The number of central lymph nodes resected and hospitalization costs were higher in the TO group as compared with those in the BA group (all p < 0.05). Conclusions An ET via the TO approach may be a good choice for unilateral PTMCs because of the shorter central neck dissection time, reduced postoperative drainage, better cosmetic satisfaction, and higher number of lymph nodes removed.

Abstract
Objective Endoscopic approaches to the craniovertebral junction (CVJ) have been established as viable and effective surgical treatments in the past decade. One of the major complications is leakage of the cerebrospinal fluid (CSF). This study aimed to investigate the efficacy and feasibility of suture closure at the nasopharyngeal mucosa upon durotomy.
Methods A series of consecutive patients who underwent different endoscopic approaches to the CVJ were retrospectively reviewed. The pathologies, surgical corridors, neurological and functional outcomes, radiological evaluations, and complications were analyzed. Different strategies of repair for the intraoperative CSF leakage were described and compared.
Results A total of 22 patients covering 13 years were analyzed. There were 12, 2, and 8 patients who underwent transnasal, transoral, and combined approaches, respectively. There were 8 patients (36.4%) who experienced intraoperative CSF leakage, and were grouped into 2: 4 in the nonsuture (NS) group and 4 in the suture-repaired (SR) group. The NS group had 3 (75%) persistent CSF leakages postoperation that caused 1 mortality, whereas patients of the SR group had only 1 minor CSF rhinorrhea that healed spontaneously within days.
Conclusion In this series of 22 patients who required anterior endoscopic resection of pathologies at the CVJ, there was 1 (4.5%) serious complication related to CSF leakage. For patients who had no durotomy, the mucosal incision at the nasopharynx usually healed rapidly and there were few procedure-related complications. For patients with intraoperative CSF leakage, suture closure was technically challenging but could significantly lower the risks of postoperative complications.

Abstract
Primary osseous tumors of the spinal column account for approximately 1% of the total number of spinal tumors found in the pediatric patient population. The authors present a case of a C1 benign giant cell lesion that was incidentally found in a 15-year-old patient. A transoral biopsy was performed followed by treatment with denosumab, with definitive management in the form of transoral tumor resection with subsequent occiput-cervical three posterior instrumented fusion. The patient tolerated all of the procedures well, as there were no post-operative complications, discharged home neurologically intact and was eager to return to school when assessed during a follow-up visit in clinic. Osteolytic lesions affecting the cervical spine are rare in the pediatric population. It is of utmost importance to have sufficient background knowledge in order to formulate a differential diagnosis, as well as an understanding of principles underlying surgical techniques required to prevent occipital-cervical instability in this patient population. The information presented will guide surgical decision-making by identifying the patient population that would benefit from neurosurgical interventions to stabilize the atlantoaxial junction, in the context of rare osteolytic conditions affecting the cervical spine.

Abstract
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 Methods We tried transoral endoscopic thyroidectomy using Soloassist II (AktorMed GmbH, Barbing, Germany) in December 2017 in our hospital. Results We 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.

Abstract
INTRODUCTION With the cumulative increase in the number of patients undergoing bariatric surgery, postoperative weight regain has become a considerable challenge. Mechanisms for weight regain are not fully understood and the process is likely multifactorial in many cases. Endoluminal revisions that reduce gastric pouch size and diameter of the gastrojejunal anastomosis may offer an effective and less invasive management strategy for this population. AREAS COVERED We critically review data from case series, retrospective and prospective studies, and meta-analyses pertaining to weight regain after gastric bypass. A variety of endoscopic revision approaches are reviewed, including technique details, procedural safety and efficacy, and post-procedure care. EXPERT COMMENTARY Given the proliferation of endoluminal therapies with evidence showing safety and efficacy in the treatment of weight regain, it is likely that endoscopic revision will be the gold standard to treat weight regain in patients with gastric bypass.

Abstract
OBJECTIVES Transoral robotic thyroidectomy (TORT) is a new remote access approach to avoid cervical incision. The purpose of this study is to compare two approaches used to avoid cervical incision: transoral approach and bilateral axillo-breast approach (BABA) in robotic thyroidectomy. METHODS A total of 90 patients were enrolled prospectively between September 2016 and April 2017. The BABA group had 43 and the TORT group had 47 patients, respectively. Parameters including clinicopathologic data, operative time, complications, laboratory data, hospital stay, postoperative pain, and cosmetic satisfaction were analyzed. RESULTS Complications were not different among the two groups. The operative time of TORT was longer than BABA until 15 cases of TORT were completed, but there was no difference after that. The Visual Analogue Scale score in TORT was lower than BABA in all the periods. TORT showed a higher cosmetic satisfaction after surgery. There was no infection or permanent mental nerve hypoesthesia in TORT. CONCLUSION Our study showed that TORT had less postoperative pain and a greater cosmetic satisfaction than the BABA. There were no significant differences in the postoperative surgical results between the two groups. TORT was comparable to the BABA in outcome with higher cosmetic satisfaction and less pain.

Abstract
OBJECTIVE Transoral surgery is becoming a preferred technique because it does not leave any scar after surgery. However, transoral surgery for a dermoid cyst of the oral cavity is not standardized yet, due to the anatomic complexity of this region. The aim of this study was to evaluate the safety and efficacy of a transoral dermoid cyst excision. STUDY DESIGN Multicenter prospective observational study. SETTING University hospital. SUBJECTS AND METHODS This study was designed as a 4-year prospective multicenter evaluation of dermoid cyst excisions within the floor of mouth. Clinical outcomes and complications related to procedures were evaluated among patients. The primary outcome was the efficacy of the procedure, and the secondary outcome was cosmetic satisfaction of each procedure. RESULTS Twenty-one patients underwent transoral dermoid cyst excisions, and 22 underwent transcervical excisions. In the transoral surgery group, the mean size of the dermoid cyst was 5.35 cm (95% CI, 4.79-5.91), and in the transcervical surgery group, it was 6.19 cm (95% CI, 5.67-6.71). There was no significant differences with respect to overall demographic characteristics between the groups. However, the duration of the operation was shorter with the transoral group than with the transcervical group ( P = .001), and cosmetic satisfaction was much better in the transoral group ( P < .001). CONCLUSION Transoral dermoid cyst excision is a potentially safe and effective method that can lead to easy and quick removal of an oral cavity dermoid cyst, with excellent cosmetic outcomes.

[PMID: 29869407 DOI: 10.1002/rcs.1930] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2017] [Revised: 05/13/2018] [Accepted: 05/13/2018] [Indexed: 11/12/2022]
Abstract
BACKGROUND The EndoMaster is a novel robot-assisted surgical system originally designed for endoscopic resection of gastrointestinal polyps and tumours. It incorporates two robotic arms (a grasper and a probe for monopolar diathermy) into the end of a flexible endoscope, creating improved manoeuvrability, with two arms allowing for 9 degrees of movement and triangulation; this enables fine manipulation and dissection of tissues. METHODS The EndoMaster was used in two human cadavers to perform 4 radical tonsillectomies to evaluate its performance in transoral robotic surgery (TORS). RESULTS The EndoMaster allowed for good visualization of the surgical field and its compact form factor allowed for quick docking and avoided the problem of clashing of the working arms. CONCLUSION The EndoMaster system shows promising potential for use in TORS. Further refinements to movements of the effector arms are required.

Abstract
OBJECTIVES/HYPOTHESIS To demonstrate anatomic relationships of the far-medial transoral endoscopic assisted approach (FMT-EAA) to the infratemporal fossa (ITF) and define the corridor dimensions, surgical freedom, and limitations associated with this approach. STUDY DESIGN Cadaveric study. METHODS Twenty ITFs (10 specimens) were dissected with the assistance of 0 °, 30 °, and 45 ° rod-lens endoscopes. Image guidance was used to confirm and measure the corridors' structural boundaries and document the anatomical relationships encountered in this approach. RESULTS Access to the ITF via the FMT-EAA can be divided into two secondary surgical corridors: the superomedial and inferolateral triangles, each of which provides access to different areas. The superomedial triangle is bounded medially by the lateral pterygoid plate and posterolateral maxillary sinus wall, superiorly by the greater sphenoid wing, and inferolaterally by the lateral pterygoid muscle. The inferolateral triangle is bounded superiorly by the lower head of the lateral pterygoid muscle, inferiorly by the medial pterygoid muscle, and laterally by the mandible. Using a standard 19-mm endoscope, the FMT-EAA achieves a mean surgical freedom of 231 mm and 161 mm in the vertical and horizontal planes, respectively. CONCLUSIONS FMT-EAA adequately exposes critical structures of the ITF. This technique is a viable option for the management of selected ITF lesions, either alone or in combination with alternative minimally invasive approaches to the region. LEVEL OF EVIDENCE NA Laryngoscope, 128:2273-2281, 2018.

Int J Oral Maxillofac Surg 2018; 47:289-295. [PMID: 28927743 DOI: 10.1016/j.ijom.2017.08.010] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2016] [Revised: 04/24/2017] [Accepted: 08/29/2017] [Indexed: 02/07/2023]
Abstract
The surgical approach to the resection of oral tongue cancers can involve transoral resection (TOR) or a temporary mandibulotomy access (TMA). There are no relevant guidelines, and the oncological safety of TOR needs consideration. The objective of this study was to investigate TMA and TOR in pT2 oral tongue cancer surgery with regard to cancer outcomes. Demographic, surgical, and histology data from primary pT2 tongue cancers were recorded and evaluated through multivariate Cox regression for local recurrence (LR), disease-free survival (DFS), and overall survival (OS). A total of 166 patients with pT2 primary oral tongue cancer fulfilled the inclusion criteria; TOR was used in 95 patients and TMA in 71 patients. The minimum follow-up was 29 months. Group comparisons showed a significantly higher frequency of perineural spread (P=0.013) in the TMA group; a higher frequency of involved margins on initial resection was seen in TOR patients (P=0.010). Adjuvant postoperative radiotherapy was preferred in the TMA group, in line with the high pN positive status. Multivariate Cox regression showed significantly higher LR and lower DFS in the TOR group despite stratification of the major prognostic factors. The 5-year survival rate was reduced to 82.2% in the TOR group, while it remained constant at 93.0% in the TMA group. TMA provided superior local control and DFS compared to TOR in pT2 tongue cancers.

Abstract
Study Design: Atlas fractures are evaluated according to the fracture type and ligamentous injury. External immobilization may result in fracture nonunion. Objective: The ideal treatment method for non-stabilized atlas fractures is limited fixation without restricting the range of motion of the atlantoaxial and atlantooccipital joints. Summary of Background Data: Such a result can be established by using either anterior fixation or posterior lateral mass fixation. However, none of these techniques can fully address anterior 1/2 atlas fractures such as in this case. Materials and Methods: A transoral technique in which bilateral screws were placed intralaminarly and connected with wire was used to reduce and stabilize an anterior 1/2 fracture of C1. Result: Radiological studies after the surgery showed good cervical alignment, no screw or wire failure and good reduction with fusion of anterior arcus of C1. Conclusions: Internal immobilization by this screw and wire osteosynthesis technique protects the mobility of the atlanto-occipital and atlantoaxial joints. The main advantage is that neither the twisted wires inserted under the anterior lamina, nor the laterally placed screw heads interfere with midline wound closure; unlike the plate/cage and rod systems used together with anterior screws. A computer navigation system with intraoperative 3D imaging facilities will be of benefit for safe placement of the screw, however we preferred a free-hand technique, as the starting point was at the fracture line along the trajectory of the routinely accessible anterior lamina.

Abstract
Background Numerous new approaches have been described over the years to improve the cosmetic outcomes of thyroid surgery. Transoral approach is a new technique that aims to achieve superior cosmetic outcomes by concealing the incision in the oral cavity. Methods Transoral thyroidectomy through vestibular approach was performed in two institutions on cadaveric models. Procedure was performed endoscopically in one institution, while the robotic technique was utilized at the other. Results Transoral thyroidectomy was successfully performed at both institutions with robotic and endoscopic techniques. All vital structures were identified and preserved. Conclusions Transoral thyroidectomy has been performed in animal and cadaveric models, as well as in some clinical studies. Our initial experience indicates the feasibility of this approach. More clinical studies are required to elucidate its full utility.

Abstract
BACKGROUND Anterior cervical fixation has been used since 1967 for multiple pathologies like traumatism, compressive myelopathy, or spinal infections. METHODS We report the case of a patient who had undergone cervical spine surgery 10 years previously and presented to our clinic with a pharyngeal fistula due to surgical screw displacement that was treated by transoral endoscopic surgery. RESULTS The immediate postoperative period occurred without incidence and complete odynophagia resolution. The patient was discharged home the fourth day after surgery. Follow-up after 1 year showed no evidence of spinal fixation hardware mobilization. CONCLUSION We consider the transoral endoscopic approach a feasible low comorbidity technique to treat anterior cervical plate mobilization with pharyngeal and pharyngoesophageal perforations.

Abstract
Gastroesophageal reflux disease (GERD) is a common condition that places a significant burden on the healthcare system. Additionally, there have been concerns raised about potential risks of long-term proton pump inhibitors. Laparoscopic anti-reflux surgery is currently the gold standard option for patients when surgery is planned. However, there continues to be interest in an endoscopic, alternative to laparoscopic surgery. Transoral incisionless fundoplication (TIF) is being increasingly utilized for such patients. We review the indications, patient selection and technique for this procedure. A video of the procedure, which we previously published on CTSNet is also attached.

Abstract
BACKGROUND Totally laparoscopic distal gastrectomy gained wide popularity in recent years. Laparoscopic total gastrectomy with intracorporeal esophagojejunostomy (LTGIE) is much less performed. In this study, we reported our preliminary experience of LTGIE using the transorally inserted anvil (OrVil). METHODS Clinical data of patients with upper gastric cancer who underwent LTGIE from January 2016 to January 2017 were retrospectively collected. The operative time, intraoperative blood loss, postoperative recovery time of intestinal function, the length of hospitalization and postoperative complications were summarized and compared between early and later cases. RESULTS There were totally 26 patients underwent LTGIE using OrVil successfully. The mean total operation time and esophagojejunostomy time was 272.8 min and 45.3 min. The mean estimated blood loss was 113.8 ml. The mean first flatus time was 3.1±0.9 days and the postoperative length of hospitalization (LOH) was 13.0±6.4 days. Three patients suffered postoperative complications, including one abdominal fluid collection, one pulmonary embolism and one pulmonary infection. During the follow-up period, neither local recurrence nor anastomosis-related morbidity was observed. CONCLUSIONS The LTGIE using OrVil is feasible and safe for upper gastric cancer. These preliminary results warrant further evaluation in a larger population to validate.

Abstract
Remote-access approaches to the thyroid gland have seen a rapid evolution recently with the development of various techniques to minimize the cosmetic and quality-of-life impact of a visible scar. Most approaches have required significantly more tissue dissection and have been limited in their extent to treat contralateral disease. The transoral approach is the most recent iteration of "scarless" thyroidectomy and offers various advantages over other techniques including less tissue dissection, equal access to both sides of the neck, and a superb midline view of the anatomy. Transoral thyroidectomy may be performed with either laparoscopic or robotic technology, each with various advantages and disadvantages. Herein, we discuss our experience with transoral robotic thyroidectomy (TORT).

Abstract
Recently, natural orifice transluminal endoscopic surgery (NOTES) has been applied in thyroid surgery with transoral access. The benefit of transoral endoscopic thyroidectomy is the potential for scar-free surgery. However, there are many concerns over some aspects, such as infection, recurrent laryngeal nerve injury, and oncological outcome. In this paper, we have reviewed the development history and the current clinical evidence of this innovative surgery. We conclude that the transoral endoscopic thyroidectomy vestibular approach (TOETVA) is feasible and can be considered no longer an experimental operation.
