Abstract
PURPOSE Ultrasound-guided puncture and punch biopsy pose a particular challenge in ultrasound examination training. These techniques should be learned and performed several times using a simulation model that is as realistic as possible before being applied to patients. While the use of agar-agar-based models is extensively documented in the literature, there is a discernible gap in publications specifically addressing their use in punch biopsy and puncture. The aim was to develop a cost-effective model for the simulation of ultrasound-guided interventions. MATERIALS AND METHODS The developed simulation model is based on the vegetable gelatine agar-agar. The agar-agar powder is boiled in water and colored. Various objects are added to the mass. Blueberries, olives, tomatoes, and cornichons imitate solid structures. Liquid-filled balloons are used to simulate cystic structures. Adding stones can make the exercises more difficult due to hyperechoic reflexes with distal shadowing. RESULTS With the model, ultrasound-guided puncture and punch biopsies could be successfully simulated, and ultrasound images can be generated for this purpose. The cost of a single model is about 2 euros. Production takes less than 2 hours, including cooling. The pure processing time is 30 minutes. The durability of the models is limited by mold, which occurs after 5 days when stored at room temperature and after 5 weeks in the refrigerator. CONCLUSION It was shown that it is possible to produce an inexpensive agar-agar-based ultrasound model in a short time and with easily available ingredients to learn ultrasound-guided puncture and punch biopsies.

Abstract
The European Society of Gastrointestinal Endoscopy (ESGE) has recognized the need to formalize and enhance training in diagnostic endoscopic ultrasound (EUS). This manuscript represents the outcome of a formal Delphi process resulting in an official Position Statement of the ESGE and provides a framework to develop and maintain skills in diagnostic EUS. This curriculum is set out in terms of the prerequisites prior to training; the recommended steps of training to a defined syllabus; the quality of training; and how competence should be defined and evidenced before independent practice. 1: Trainees should have achieved competence in upper gastrointestinal endoscopy before training in diagnostic EUS. 2: The development of diagnostic EUS skills by methods that do not involve patients is advisable, but not mandatory, prior to commencing formal training in diagnostic EUS. 3: A trainee's principal trainer should be performing adequate volumes of diagnostic EUSs to demonstrate maintenance of their own competence. 4: Training centers for diagnostic EUS should offer expertise, as well as a high volume of procedures per year, to ensure an optimal level of quality for training. Under these conditions, training centers should be able to provide trainees with a sufficient wealth of experience in diagnostic EUS for at least 12 months. 5: Trainees should engage in formal training and supplement this with a range of learning resources for diagnostic EUS, including EUS-guided fine-needle aspiration and biopsy (FNA/FNB). 6: EUS training should follow a structured syllabus to guide the learning program. 7: A minimum procedure volume should be offered to trainees during diagnostic EUS training to ensure that they have the opportunity to achieve competence in the technique. To evaluate competence in diagnostic EUS, trainees should have completed a minimum of 250 supervised EUS procedures: 80 for luminal tumors, 20 for subepithelial lesions, and 150 for pancreaticobiliary lesions. At least 75 EUS-FNA/FNBs should be performed, including mostly pancreaticobiliary lesions. 8: Competence assessment in diagnostic EUS should take into consideration not only technical skills, but also cognitive and integrative skills. A reliable valid assessment tool should be used regularly during diagnostic EUS training to track the acquisition of competence and to support trainee feedback. 9: A period of supervised practice should follow the start of independent activity. Supervision can be delivered either on site if other colleagues are already practicing EUS or by maintaining contacts with the training center and/or other EUS experts. 10: Key performance measures including the annual number of procedures, frequency of obtaining a diagnostic sample during EUS-FNA/FNB, and adverse events should be recorded within an electronic documentation system and evaluated.

Abstract
Interventional endoscopic ultrasound (IEUS) has gained significant popularity in recent years because of its diagnostic and therapeutic capabilities. The proper training of endoscopists is critical to ensure safe and effective procedures. This review study aims to assess the impact of different training models on the competence of trainees performing IEUS. Eight studies that evaluated simulators for IEUS were identified in the medical literature. Various training models have been used, including the EASIE-R, Mumbai EUS, EUS Magic Box, EndoSim, Thai Association for Gastrointestinal Endoscopy model, and an ex vivo porcine model (HiFi SAM). The trainees underwent traditional didactic lectures, hands-on training using simulators, and direct supervision by experienced endoscopists. The effectiveness of these models has been evaluated based on objective and subjective parameters such as technical proficiency, operative time, diagnostic success, and participant feedback. As expected, the majority of skills were improved after the training sessions concluded, although the risk of bias is high in the absence of external validation. It is difficult to determine the ideal simulator among the existing ones because of the wide variation between them in terms of costs, reusability, design, fidelity of anatomical structures and feedback, and types of procedures performed. There is a need for a standardized approach for the evaluation of IEUS simulators and the ways skills are acquired by trainees, as well as a clearer definition of the key personal attributes necessary for developing a physician into a skilled endoscopist capable of performing basic and advanced therapeutic EUS interventions.

Abstract
INTRODUCTION Eco-guided interventionism has changed the way Physical Medicine and Rehabilitation specialists deal with musculoskeletal pain and other problems such as spasticity. The implementation of the Eco-Guided Intervention Units improves the results of the usual minimally invasive treatments in our speciality's clinical practice. The biggest drawback of this practice is the long learning curve and the difficulty of practice during training courses. OBJECTIVE To develop a system of phantoms that allow the practice of interventionism in anatomical models by shortening learning times and improving certainty by achieving the objective of interventionist practice. METHODS Describes the method of manufacturing three-dimensional models of joints with images obtained from computerized axial tomography, and their subsequent inclusion in gelatin's made molds, which allow to obtain phantoms, similar to real joint models, that allow to study using ultrasound techniques, and the practice of eco-guided interventionism. CONCLUSION Three-dimensional joint models made with gelatin are useful in the practice and learning of joint eco-guided interventionism techniques.

Abstract
Background and Objectives EUS-guided biliary drainage (EUS-BD) required a dedicated training. We developed and evaluated a nonfluoroscopic, all-artificial training model known as Thai Association for Gastrointestinal Endoscopy Model 2 (TAGE-2) for the training of EUS-guided hepaticogastrostomy (EUS-HGS) and EUS-guided choledochoduodenostomy (EUS-CDS). We hypothesize that trainers and trainees would appreciate the ease of the nonfluoroscopy model and increase their confidence to start their real procedures in humans. Materials and Methods We prospectively evaluated the TAGE-2 launched in two international EUS hands-on workshops and have followed trainees for 3 years to see long-term outcomes. After completing the training procedure, the participants answered questionnaires to assess their immediate satisfaction of the models in and also the impact of these models on their clinical practice 3 years after the workshop. Results A total of 28 participants used the EUS-HGS model and 45 participants used the EUS-CDS model. The EUS-HGS model was rated as excellent by 60% of beginners and 40% by experienced and the EUS-CDS model was rated as excellent by 62.5% of beginners and 57.2% of experienced. The majority of trainees (85.7%) have started the EUS-BD procedure in humans without additional training in other models. Conclusion Our nonfluoroscopic, all-artificial model for EUS-BD training is convenient to be used with good-to-excellent satisfaction scored by the participants in most aspects. It can help the majority of trainees start their procedures in humans without additional training in other models.

Abstract
BACKGROUND In teaching hospitals, the majority of central venous lines (CVL) are placed by trainees, resulting in little opportunity for attending critical care physicians to maintain this procedural skill. Additionally, not all attending critical care physicians have been trained in the most up-to-date method of dynamic ultrasound (US) guided CVL placement. Furthermore, there is no standardized method to assess procedural competency of attending critical care physicians or to train them in the evolving practice of CVL placement. Despite these limitations, attending critical care physicians are ultimately responsible for supervision of CVL placement by trainees. OBJECTIVE To assess the utility of an instructional video to impact attending critical care physicians' competency and confidence in dynamic US guided CVL placement. METHODS A pre-post intervention study was conducted at an academic medical center. Attending critical care physicians were first asked to obtain CVL access on a gelatin model using US guidance. They then participated in the intervention, which consisted of watching a short instructional video demonstrating a method of dynamic US guided CVL placement. They were then asked to obtain access again, this time using the described method. All CVL placements were video recorded to assess competency in dynamic US guided CVL placement as well as the time required to obtain CVL access. Two blinded and independent reviewers evaluated each video with discrepancies resolved by a third reviewer. Participants were also surveyed pre and post intervention to assess their confidence in performing and supervising CVL placement. RESULTS A total of 21 attending critical care physicians were included. Pre-intervention, four used dynamic US guidance compared to 16 post-intervention (P < .001). Confidence in both CVL placement and supervision improved post-intervention (P = .03 each). Time required to obtain CVL access did not differ significantly pre and post intervention. The majority (20/21) believed there should be required competency testing for CVL placement. CONCLUSIONS Pre-intervention dynamic US guided CVL competency was poor in this sample of attending critical care physicians but improved significantly with an instructional video intervention. This study suggests there is a role for procedural competency testing among attending critical care physicians, and that significant improvement is achievable with relatively minimal instruction.

Abstract
Background and Objectives: EUS has evolved into a therapeutic modality for gastrointestinal disorders. Simulators, ex vivo models, and phantoms are the current teaching methods for therapeutic EUS (TEUS). We create and evaluate a high-fidelity simulated live animal model (HiFi SAM) for teaching endoscopists TEUS. Materials and Methods: Designing a curriculum that uses HiFi SAM and enables trainees to perform realistic procedures with expert mentors. Results: Twenty-seven trainees participated in a 3-day program with 6 h of theoretical and 14 h of hands using life HiFi SAM. Eighteen experts participated. Twenty-two (20–25) TEUS were defined for each HiFi SAM, and 616 were performed in all. Of 616/264 (43%) were evaluated with a mean of 88 per course (ranging between 80 and 95). Ninety-one percent (240/264) of the procedures were completed successfully. In 24, success was not achieved due to technical and/or model problems. Student rating of HiFi SAM was: 71% excellent rating (scale 8–10) and 95% excellent/good. The HiFi SAM procedure evaluation was (scale 1–5): fine-needle biopsy: 4.79, radiofrequency: 4.76, common bile duct and gallbladder drainage: 4.75, cystic drainages: 4.72, neurolysis: 4.55, microbiopsy: 4.50, and hepatogastric drainage: 4.04, with an overall satisfaction rate of 4.56 (91%). A short survey showed: 83% would recommend absolutely (17% most likely), 33% think that ITEC training was sufficient for their practice, and 66% would like additional training, especially more practice in specific techniques rather than more clinical case discussion. Regarding impact on their practice, 66% of the trainees started a new procedure and/or noted improvement in previous ones. Conclusion: HiFi SAM is a complex model; however, experts and trainees are satisfied with the training this new curriculum provided.

Abstract
Ultrasound (US)-guided central venous catheter (CVC) insertion is a procedure that carries the risk of significant complications. Simulation provides a safe learning atmosphere, but most CVC simulators are not available outside of simulation centers. To explore longitudinal trends in US-guided CVC insertion competency in internal medicine (IM) interns, we studied the use of a low-fidelity, gelatin-based, US-guided CVC insertion simulation model combined with a simulation curriculum. This prospective observational study of IM interns was performed over the course of one academic year. Interns (n = 56) underwent model-based, US-guided procedure simulation training program and a repeated training course prior to their intensive care unit (ICU) rotation. CVC insertion competency at different timepoints was recorded. Survey data about intern experience and attitudes were also collected. Out of the 56 interns initially trained, 40 were included in the final analysis. Across all outcomes, interns experienced skill atrophy between initial training and the beginning of their ICU month. However, by the end of the month, there was a significant improvement in competency as compared to initial procedural training, which then waned by the end of the intern year. Attitudes toward the model were generally positive and self-reported confidence improved throughout the course of the year and correlated with objective measures of competency. Over the course of their intern year, which included simulation training using a gelatin-based model, interns demonstrated consistent competency trends. The use of a gelatin-based CVC insertion simulation model warrants further study as an adjunctive aid to existing simulation training.

Abstract
Background and Objectives: EUS-FNA is applied widely in clinical practice, but there remains a lack of authentic training models. The present study aimed to develop a novel swine training model and to perform a preliminary assessment of its feasibility and efficacy. Materials and Methods: To create an internal lesion-like target, empty shells of iodine-125 seeds were implanted into the caudate lobe of the liver in Bama minipigs. A training program involving 10 trainees was subsequently carried out, in which a total of 60 needlings were performed, composed of 6 for each trainee obtained during two training steps. Comparisons of procedure-related variables were conducted between the two. Trainees completed a questionnaire to assess their basic endoscopic experiences and reasonability of the model. Results: A target region of 2.0 cm × 2.0 cm in diameter was successfully established on the caudate lobe in all implanted pigs. In the training program, the average procedure time decreased from the first to the second step and the average time for the total 30 needlings' obtainment was significantly shorter for the second training step (23.8 ± 4.5 min vs. 40.9 ± 9.0 min, P < 0.001). For the second step, there was also a significant improvement in total success rate (86.7% vs. 56.7%, P = 0.020) and accuracy rate (76.7% vs. 43.3%, P = 0.017). All trainees scored the effectiveness of the model highly and all reported improved confidence after the training. Conclusion: This novel swine training model could authentically mimic clinical EUS-FNA, providing an effective in vivo practice tool for novices before clinical practice.

Abstract
BACKGROUND AND AIMS Simulation refers to educational tools that allow for repetitive instruction in a nonpatient care environment that is risk-free. In GI endoscopy, simulators include ex vivo animal tissue models, live animal models, mechanical models, and virtual reality (VR) computer simulators. METHODS After a structured search of the peer-reviewed medical literature, this document reviews commercially available GI endoscopy simulation systems and clinical outcomes of simulation in endoscopy. RESULTS Mechanical simulators and VR simulators are frequently used early in training, whereas ex vivo and in vivo animal models are more commonly used for advanced endoscopy training. Multiple studies and systematic reviews show that simulation-based training appears to provide novice endoscopists with some advantage over untrained peers with regard to endpoints such as independent procedure completion and performance time, among others. Data also suggest that simulation training may accelerate the acquisition of specific technical skills in colonoscopy and upper endoscopy early in training. However, the available literature suggests that the benefits of simulator training appear to attenuate and cease after a finite period. Further studies are needed to determine if meeting competency metrics using simulation will predict actual clinical competency. CONCLUSIONS Simulation training is a promising modality that may aid in endoscopic education. However, for widespread incorporation of simulators into gastroenterology training programs to occur, simulators must show a sustained advantage over traditional mentored teaching in a cost-effective manner. Because most studies evaluating simulation have focused on novice learners, the role of simulation training in helping practicing endoscopists gain proficiency using new techniques and devices should be further explored.

Abstract
Image-guided interventions are widely employed in clinical medicine, which brings significant revolution in healthcare in recent years. However, it is impossible for medical trainees to experience the image-guided interventions physically in patients due to the lack of certificated skills. Therefore, training phantoms, which are normally tissue mimicking materials, are widely used in medical research, training, and quality assurance. This review focuses on the tissue mimicking materials used in image-guided needle-based interventions. In this case, we need to investigate the microstructure characteristics and mechanical properties (for needle intervention), optical properties and acoustical properties (for imaging) of these training phantoms to compare with the related properties of human real tissues. The widely used base materials, additives and the corresponding concentrations of the training phantoms are summarized from the literatures in recent ten years. The microstructure characteristics, mechanical behavior, optical properties and acoustical properties of the tissue mimicking materials are investigated, accompanied with the common experimental methods, apparatus and theoretical algorithm. The influence of the concentrations of the base materials and additives on these characteristics are compared and classified. In this review, we assess a comprehensive overview of the existing techniques with the main accomplishments, and limitations as well as recommendations for tissue mimicking materials used in image-guided needle-based interventions.

Abstract
BACKGROUND Deliberate practice of invasive procedures on simulation phantoms has been recommended to teach trainees. For many departments, these task trainers can be prohibitively expensive. Sometimes, phantoms for specialized procedures are not commercially available at all. There are currently are no commercially available simulation phantoms for the purpose of ultrasound (US)-guided glenohumeral joint injection. OBJECTIVES The objective was to create a low-cost, reusable, homemade simulation phantom for US-guided glenohumeral joint injection using easily obtainable materials as well as to determine whether use of such a homemade model by novice learners is associated with increased self-reported comfort level and knowledge of the procedure. METHODS Fourth-year emergency medicine-bound medical students and PGY-1 residents were asked to participate in a hands-on 30-minute training session for US-guided glenohumeral joint injection using a homemade simulation phantom. Participants were assessed by pre- and postintervention survey of self-reported comfort levels with the procedure. Outcomes were measured on modified global rating scale (GRS; minimum = 1, maximum = 7). The primary outcome was learner comfort with US-guided glenohumeral joint injection. Secondary outcomes were comfort level in obtaining adequate US image and identifying landmarks of the glenohumeral joint as well as likelihood to perform US-guided injection of the glenohumeral joint in a clinical setting. RESULTS In the primary outcome, mean GRS scores in 13 participants for comfort with the procedure increased from 2.7 to 5.0 (p < 0.01) after intervention. Mean GRS for knowledge of anatomy increased from 2.8 to 5.4 (p < 0.01) and mean GRS for comfort in image acquisition increased from 2.8 to 5.3 (p < 0.01). Mean GRS for likelihood to perform the procedure trended toward increase from 4.6 to 5.5 (p = 0.25). CONCLUSIONS Use of a homemade, low-cost, ballistic gelatin US phantom for simulation of glenohumeral intraarticular injection was associated with increased learner comfort with the procedure.

Abstract
Background: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is essential in the management of digestive cancers. However, teaching and learning this technique remain challenging due to the lack of cost-effective models. Material and methods: This was a prospective experimental study using a complete porcine upper gastrointestinal ex-vivo organ package, placed in an Erlangen Active Simulator for Interventional Endoscopy (EASIE-R), and prepared with one cyst and two solid masses (2 cm). Five fellows inexperienced in EUS-FNA were enrolled, performing 10 procedures on each lesion, alternatively. The total time, number of attempts for success, of needle view losses, and of scope handling were recorded, associated with an independent skills rating by procedure. We compared the first 15 procedures with the last 15 for each fellow. Results: The fellows successfully performed all procedures in 2 to 40 minutes, requiring 1 to 6 attempts. All (5/5) improved their total time taken (P < 0.001), number of times when the EUS view of the needle was lost (P < 0.05), scope handling (P < 0.005), and skills rating (P < 0.001), whereas 4/5 (80 %) improved their number of attempts. The overall evaluation showed a significant decrease (P < 0.001) in the total time taken (11.2 ± 7.8 vs 4.3 ± 2.2 minutes), number of attempts (2.6 ± 1.2 vs 1.2 ± 0.7), number of times when the EUS view of the needle was lost (2.3 ± 2 vs 0.5 ± 0.7), and need for scope handling (1.1 ± 1.7 vs 0.1 ± 0.2). We also observed an improvement in skills rating (5 ± 1.9 vs. 7.7 ± 1.1). Conclusion: This newly designed ex-vivo model seems to be an effective way to improve the initial learning of EUS-FNA, by performing 30 procedures.

Abstract
Endoscopic ultrasonography (EUS) has become a useful diagnostic and therapeutic modality in gastrointestinal endoscopy. However, EUS requires additional training since it requires simultaneous endoscopic manipulation and ultrasonographic interpretation. Obtaining adequate EUS training can be challenging since EUS is highly operator-dependent and training on actual patients can be associated with an increased risk of complications including inaccurate diagnosis. Therefore, several models have been developed to help facilitate training of EUS. The models currently available for EUS training include computer-based simulators, phantoms, ex vivo models, and live animal models. Although each model has its own merits and limitations, the value of these different models is rather complementary than competitive. However, there is a lack of objective data regarding the efficacy of each model with recommendations on the use of various training models based on expert opinion only. Therefore, objective studies evaluating the efficacy of various EUS training models on technical and clinical outcomes are still needed.

Abstract
Background and Objectives: Endoscopic transmural puncture cysts and drainage pancreatic fluid collections are an important part of endoscopic ultrasound practices, but can be technically difficult to master, particularly with regards to placing stents. We developed an ex-vivo model that is inexpensive and can be used for cyst puncture and fluid collection drainage. Methods: Over the last 5 years, we have perfected the creation of this ex-vivo model. The model is easy and inexpensive to create and multiple aspirations and device placements and removals into a single cavity with decompression. The model allows the use of cautery devices and placement of expandable metal stents. Additionally, the contents in the model can be altered to appear as walled-off necrotic collections endosonographically. Results: The model can be created for <300 US dollars. It has been used at multiple international conferences for teaching purposes and can withstand up to 10 puncture and drainages without having to replace the “cyst.” The cyst can easily be exchanged for other prepared cysts. Preliminary surveys obtained from users show ratings that are realistic. Conclusions: A new ex-vivo model can be easily and economically created, is realistic and can be used multiple times during the single training session.

Abstract
BACKGROUND A reproducible large animal model of bile duct dilation for the preclinical testing of new biliary devices and for training endoscopic biliary intervention is required. Surgical methods are mainly used to produce large animal models of biliary obstruction. OBJECTIVE To develop an animal model of bile duct dilation using endoscopic methods and to compare the merits of endoclips and detachable snares for the obstruction of major duodenal papillae. DESIGN Proof of concept experimental study. SETTINGS Animal laboratory. INTERVENTIONS Endoscopic clipping of the major duodenal papilla or closure of the major duodenal papilla with a detachable snare. MAIN OUTCOME MEASUREMENTS Feasibility, efficacy, and safety of endoscopic methods to develop swine models with bile duct dilation were estimated by degree of dilation at the common bile duct (CBD), intrahepatic duct (IHD), and gallbladder (GB). RESULTS All animals survived until the end of the experiment. Clipping of the major duodenal papilla and closure of the major duodenal papilla with a detachable snare were performed successfully in all swine. No technical difficulty or adverse event occurred during the procedures. Biliary dilatations in all animals were observed on cholangiograms (mean Δ% of postprocedural and preprocedural maximum diameters: CBD, 301%; IHD, 223.5%; GB, 34.8%). Degree of bile duct dilation in the snare group tended to be greater (CBD, 367.3%; IHD, 298.3%; GB, 47.8%) than in the endoclip group (CBD, 234.7%; IHD, 148.7%; GB, 21.8%), but this difference was not significant. An analysis of degrees of dilation according to location in the biliary tree showed that the GB was not dilated as well as the CBD or IHD. LIMITATIONS Animal model. CONCLUSION The 2 endoscopic procedures described are effective and safe for creating a swine model of bile duct dilation and could be helpful for training biliary intervention and for endoscopic biliary studies.

Abstract
Like any other technique, fine needle aspiration (FNA) proficiency requires adequate experience. Although this technique is not difficult to master, formal training will allow endosonographers to achieve better results. The following article is derived in two parts: (1) To review current knowledge on endoscopic ultrasound (EUS)-FNA training, discuss the current recommendations on training guidelines, explore other training adjuncts and review the latest studies evaluating the validity of current recommendations; and (2) to provide some basic grounds on the EUS-FNA technique. EUS-FNA can be broken down into a series of steps. Proper execution of each step will make FNA easier and likely increase its diagnostic yield. Adequate positioning of the lesion in regards to the ultrasound probe is a key factor to obtain best results. The following will discuss useful tips in order to achieve maximal success rates.

Abstract
INTRODUCTION Central vein catheterization (CVC) plays a central role in hospital patient management. Compared with the use of traditional anatomical landmarks, ultrasound-guidance is associated with higher CVC success rates, fewer complications, and more rapid central venous access. The use of US-guided CVC in clinical practice has not become widespread, largely because anesthesiology and general surgery residents receive limited training in this technique. To increase the use of US-guided CVC in our surgical department, we organized a hands-on training program based on the use of handmade models. METHODS Three different models were constructed using plastic food-storage containers, segments of rubber tourniquet and silastic tubing (to simulate vessels), and agar gelatin. RESULTS The hands-on training course allowed progressive acquisition of the basic hand-eye coordination skills necessary for performing US-guided venipuncture. The overall cost for each model was less than €5.00. DISCUSSION The models described in this report are useful tools for teaching US-guided CVC. Thanks to their low-cost, they can be widely used to facilitate the introduction of this technique in clinical practice.

Abstract
Clearly, the potential applications for simulation training in endoscopy are vast. Endoscopy models may serve as a platform to introduce new skills, to maintain proficiency, or even to assess competency. As these applications are explored fully, the strengths and weaknesses of specific devices will dictate their roles. Educators must ensure that these roles are founded on reliable research but remain mindful that simulators are only tools to augment clinical training, with the goal of benefiting both student and patient, and are not a replacement for patient-based experience.

Abstract
Endoscopic ultrasound (EUS) is one of the most challenging endoscopic procedures to learn and requires integration of both cognitive and endoscopic skills. EUS also is an important technology with a growing number of therapeutic applications. Despite its increasing role in managing gastrointestinal diseases, EUS technology remains largely limited to the confines in academic medical centers and tertiary referral centers because of issues concerning cost, equipment availability, efficiency of implementation, reimbursement, and most importantly, training. This article reviews the factors that are considered important for EUS training and discusses the use of various simulators and the potential role of these simulators in the future.

Abstract
The relationship between Helicobacter pylori infection and gastroesophageal reflux disease (GERD) remains controversial. Over 20 studies presented at the 2003 Digestive Disease Week meeting examined the implications of H. pylori infection for GERD. Although the findings were not uniform, most of the studies presented indicated a negative association between the presence of H. pylori and the presence of GERD symptoms, signs, or complications. In addition, eradication of H. pylori infection was related to the emergence of GERD and its complications. However, most studies favored a role for H. pylori rather than GERD in the development of pathologic changes in the gastric cardia. Finally, a few studies suggested the intriguing possibility that the modulation of GERD by H. pylori could be through the effects of H. pylori eradication on weight gain.
