Abstract
OBJECTIVE Three-dimensional (3D) endoscopy has been developed to provide depth perception to allow for improved visualisation during otolaryngology surgery. We conducted a systematic review to determine the surgical safety and efficacy of 3D endoscopy in comparison to two-dimensional (2D) endoscopy in performing otolaryngology procedures, and the role of 3D endoscopy as a training tool for novice otolaryngology surgeons. METHODS Primary studies were identified through MEDLINE, Embase and Web of Science databases, which were searched for articles published through June 2022 that compared the outcomes of 2D and 3D endoscopy in otolaryngology surgical procedures or otolaryngology-relevant simulations. Candidate articles were independently reviewed by two authors. RESULTS A total of 18 full-text articles met inclusion criteria for this study. In clinical trials (n = 8 studies, 362 subjects), there were no significant differences in performance time, intraoperative or postoperative complications with 3D endoscopes when compared to 2D. In simulation studies (n = 10 studies, 336 participants), 3D endoscopes demonstrated a decreased error rate (n = 5 studies) and shorter performance time (n = 3 studies). Studies also reported improved depth perception (n = 14 studies) and visualisation preference (n = 5 studies) with 3D over 2D systems. The 3D systems were found to have a shorter learning curve and better manoeuvrability among novice surgeons. CONCLUSION 3D endoscopy showed equivalent safety and efficacy compared to 2D endoscopy in otolaryngology surgery. The improved depth perception and performance for novices using 3D endoscopes suggests the technology may be superior to 2D endoscopes as a training tool for otolaryngology surgeons.

Abstract
Traction techniques have emerged as a desirable "second-hand" while performing endoscopic submucosal dissection (ESD), enabling adequate visualization of submucosal tissue and vasculature, which allows for safe and efficient dissection. Multiple traction techniques have been developed over the years, and these can be broadly divided into internal and external traction techniques. This arsenal of techniques allows for traction that is personalized to the location of the lesion undergoing ESD. Mastering traction techniques requires structured training, and understanding of the benefits and pitfalls of each technique. Future research and development efforts need to focus on pathways and curriculums for trainees to master the currently available endoscopic traction techniques and provide avenues for the development of newer traction modalities.

Abstract
Background Accurate mediastinal staging of lung cancer patients is critical for determining appropriate treatment. Mediastinoscopy and endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration are the most commonly utilized techniques. Limited data exist on training and practice trends among thoracic surgeons. We aimed to determine training and practice patterns and find whether there is a paradigm shift in mediastinal staging after the introduction of EBUS into practice among thoracic surgeons in the United States. Methods 28-question survey was constructed querying demographic, training, and practice patterns with mediastinoscopy and EBUS and was sent to practicing thoracic surgeons in the United States. Descriptive statistics were used to summarize quantitative data. Results Ninety-eight responded with a 93% completion rate. Eighty-seven percent of respondents received training in EBUS and 70% perform EBUS routinely. All respondents believe EBUS should be incorporated into thoracic surgery training curriculums. Majority of those who prefer EBUS feel EBUS is safer than mediastinoscopy, allows access to lymph nodes stations or lesions inaccessible by mediastinoscopy and prefer EBUS to avoid re-do mediastinoscopy and in irradiated mediastinum. Majority of those who prefer mediastinoscopy reported they perform more accurate staging compared to EBUS, that mediastinoscopy is more accurate in diagnosing lymphoma or sarcoidosis and that frozen section can be done at the same interval as resection. Among surgeons who prefer EBUS, 94% biopsy 3 or more lymph node stations, 86% routinely biopsy hilar (N1) nodes while 8% never biopsy N1 nodes. Of surgeons who prefer mediastinoscopy. Ninety-seven percent biopsy 3 or more lymph node stations, only 27% routinely biopsy N1 nodes and 70% never biopsy N1 nodes. Conclusions EBUS is used frequently by thoracic surgeons in their practice for mediastinal staging. Methods of obtaining proficiency in EBUS widely varied among surgeons. In addition to mediastinoscopy, dedicated EBUS training should be incorporated into thoracic surgery training curriculums.

Abstract
Obesity represents a growing public health threat. Until recently, surgery was the primary means for treating pharmacotherapy resistant obese patients. However, therapeutic endoscopy has evolved as an effective and safe alternative strategy. Particularly, endoscopic bariatric therapy (EBT) can bridge the gap in patients who do not fit the BMI criteria for surgery and fail conservative or medical therapy. Today there are many tools within the realm of EBT available to endoscopists. While there are no formal guidelines for their use, training and use of these tools are limited by the type of institution, preferences of senior endoscopists, cost, and availability. We review different EBT tools available to trainees and gastroenterologist, and the learning curves associated with them.

Abstract
OBJECTIVES/HYPOTHESIS Three-dimensional (3D) endoscopy is an emerging tool in surgery that provides real-time depth perception. Its benefits have been investigated in surgical training, but the current literature lacks significant objective outcome data. We aimed to objectively compare the efficacy of two-dimensional (2D) versus 3D high-definition endoscopes in novice users. STUDY DESIGN Prospective, randomized crossover study. METHODS Ninety-two novice medical students who used both 2D and 3D endoscopes to complete two validated tasks in a box trainer participated in the study. Time taken and error rates were measured, and subjective data were collected. RESULTS Wilcoxon tests showed 3D technology was significantly faster than 2D (78 vs. 95 seconds, P = .004), and errors per task were significantly lower (3 vs. 5, P < .001). Sixty-nine percent of participants preferred the 3D endoscope. CONCLUSIONS 3D high-definition endoscopy could be instrumental in training the next generation of endoscopic surgeons. Further research is required in a clinical setting. LEVEL OF EVIDENCE 2b Laryngoscope, 129:1280-1285, 2019.

Abstract
Introduction: Functional endoscopic sinus surgery is a complex procedure used by otorhinolaryngologists to treat a host of nasal sinus pathologies. Due to the involved nasal anatomy and the nature of the procedure, teaching residents to use an endoscope is challenging. Simulation labs have been helpful but intraoperative instruction can still present difficulty in communication between resident and attending physicians during the teaching process. The purpose of this is to hypothesize a method of teaching intraoperatively that can be used supplemental to or independently of virtual reality teaching. Method: Literature review to determine current intraoperative verbal teaching methods used by surgeons was performed. Review was also performed on the effects of simulation techniques in preparing residents for the operating room. Although this was not a systematic review including statistical analysis, a gap was found in the literature on how residents can be efficiently taught intraoperatively to navigate an endoscope while maintaining patient safety. A novel and inexpensive method has been devised as a possible teaching method. Conclusions: Extensive literature is not available in intraoperative teaching techniques. It is therefore uncertain whether such a method has been used before. Further study, possibly in the form of surveys and intraoperative trials, must be done to determine the effectiveness of this mechanism.

Abstract
Endoscopic eradication therapy (EET), the standard of care for treatment of Barrett's esophagus with dysplasia and early neoplasia, consists of a combination of endoscopic resection and ablative modalities. Resection techniques primarily include endoscopic mucosal resection or endoscopic submucosal dissection. Resection of nodular disease is generally followed by one of multiple ablative therapies among which radiofrequency ablation has the best evidence supporting safety and efficacy. These advanced endoscopic procedures require both experience and expertise in the cognitive and procedural aspects of EET. However, very few formal programs exist that teach endoscopists the necessary skills to perform EET in a safe, standardized, and efficacious manner. Case volume at both the endoscopist and center level has been shown to impact clinical outcomes based on limited data. As a result, some recent guidelines endorse case volume as a measure of competency. Quality indicators, which can be used as benchmarks for training and as part of pay for quality initiatives, have recently been derived for EET. However, quality metrics in EET have not been widely accepted, nor are they broadly used currently. While the efficacy of EET for BE is established, there is a need for application of quality metrics to both assure adequate training in these procedures, as well as to assess treatment outcomes. A standardized EET training curriculum during endoscopic training, with competency assessment of both new clinicians and endoscopists in practice has potential to improve care in EET.

Abstract
INTRODUCTION Endoscopic retrograde cholangiopancreatography (ERCP) is a technically challenging procedure performed by both surgeons and gastroenterologists. There is controversy in the field regarding the training necessary to perform ERCP. Widely disparate requisite volumes of experience to achieve proficiency have been published by representatives of each specialty. The basis for these differences has not been fully explored, with particular reference to the cognitive mindset of the different specialties. METHODS Structured cognitive task analytic interviews were conducted with 7 expert gastroenterologists and 4 expert surgeons from 4 institutions, each of whom performs ERCP as a common procedure in their clinical practice. A qualitative analysis and grounded theory approach was used, focusing specifically on duct cannulation as a critical procedural element. Transcripts were analyzed using Atlas.ti software. RESULTS The qualitative analysis of 11 transcripts identified 173 unique codes from a total of 653 quotes. In all, 5 themes were found to describe the codes: judgment, teaching, techniques, principles, and equipment. Significant differences were noted between gastroenterologists and surgeons across these themes. Gastroenterologists placed emphasis on issues of judgment including rationale, and emphasized explanation and clarification in teaching. Surgeons placed more emphasis on use of visual cues, and emphasized technique and equipment nuances. CONCLUSION The data suggest that gastroenterologists deconstruct ERCP competence based on application of rules and rationale through reflection. Surgeons focus more on visual and tactile cues in task deconstruction, and may be more likely to measure proficiency based on technical response to such cues. Based on this study, it is proposed that both specialties might have complementary roles in training therapeutic endoscopists.

Abstract
BACKGROUND Accurate prediction of Helicobacter pylori infection status on endoscopic images can contribute to early detection of gastric cancer, especially in Asia. We identified the diagnostic yield of endoscopy for H. pylori infection at various endoscopist career levels and the effect of two years of training on diagnostic yield. METHODS A total of 77 consecutive patients who underwent endoscopy were analyzed. H. pylori infection status was determined by histology, serology, and the urea breast test and categorized as H. pylori-uninfected, -infected, or -eradicated. Distinctive endoscopic findings were judged by six physicians at different career levels: beginner (<500 endoscopies), intermediate (1500-5000), and advanced (>5000). Diagnostic yield and inter- and intra-observer agreement on H. pylori infection status were evaluated. Values were compared between the two beginners after two years of training. The kappa (K) statistic was used to calculate agreement. RESULTS For all physicians, the diagnostic yield was 88.9% for H. pylori-uninfected, 62.1% for H. pylori-infected, and 55.8% for H. pylori-eradicated. Intra-observer agreement for H. pylori infection status was good (K > 0.6) for all physicians, while inter-observer agreement was lower (K = 0.46) for beginners than for intermediate and advanced (K > 0.6). For all physicians, good inter-observer agreement in endoscopic findings was seen for atrophic change (K = 0.69), regular arrangement of collecting venules (K = 0.63), and hemorrhage (K = 0.62). For beginners, the diagnostic yield of H. pylori-infected/eradicated status and inter-observer agreement of endoscopic findings were improved after two years of training. CONCLUSIONS The diagnostic yield of endoscopic diagnosis was high for H. pylori-uninfected cases, but was low for H. pylori-eradicated cases. In beginners, daily training on endoscopic findings improved the low diagnostic yield.
