Khan, R, Plahouras, J, Johnston, BC, Scaffidi, MA, Grover, SC, Walsh, CM
Endoscopy. 2019;(7):653-664
Abstract
BACKGROUND Endoscopy programs are increasingly integrating simulation training. We conducted a systematic review to determine whether virtual reality (VR) simulation training can supplement and/or replace conventional patient-based endoscopy training for health professional trainees with limited or no prior endoscopic experience. METHODS We searched medical, educational, and computer literature databases in July 2017 for trials that compared VR simulation training with no training, conventional training, another form of simulation training, or an alternative method of VR training. We screened, abstracted data, and performed quantitative analysis and quality assessment through Cochrane methodology. RESULTS We included 18 trials with 3817 endoscopic procedures. VR training provided no advantage over no training or conventional training based on the primary outcome of composite score of competency. VR training was advantageous over no training based on independent procedure completion (relative risk [RR] = 1.62, 95 % confidence interval [CI] 1.15 - 2.26, moderate-quality evidence), overall rating of performance (mean difference [MD] 0.45, 95 %CI 0.15 - 0.75, very low-quality evidence), and mucosal visualization (MD 0.60, 95 %CI 0.20 - 1.00, very low-quality evidence). Compared with conventional training, VR training resulted in fewer independent procedure completions (RR = 0.45, 95 %CI 0.27 - 0.74, low-quality evidence). We found no differences between VR training and no training or conventional training for other outcomes. Based on qualitative analysis, we found no significant differences between VR training and other forms of simulation training. VR curricula based in educational theory provided benefit with respect to composite score of competency, compared with unstructured curricula. CONCLUSIONS : VR simulation training is advantageous over no training and can supplement conventional endoscopy training. There is insufficient evidence that simulation training provides benefit over conventional training.

Abstract
The European Society of Gastrointestinal Endoscopy (ESGE) together with the United European Gastroenterology (UEG) recently developed a short list of performance measures for small-bowel endoscopy (i.e. small-bowel capsule endoscopy and device-assisted enteroscopy) with the final goal of providing endoscopy services across Europe with a tool for quality improvement. Six key performance measures both for small-bowel capsule endoscopy and for device-assisted enteroscopy were selected for inclusion, with the intention being that practice at both a service and endoscopist level should be evaluated against them. Other performance measures were considered to be less relevant, based on an assessment of their overall importance, scientific acceptability, and feasibility. Unlike lower and upper gastrointestinal endoscopy, for which performance measures had already been identified, this is the first time small-bowel endoscopy quality measures have been proposed.

Endoscopy in Postoperative Patients with Crohn's Disease or Ulcerative Colitis. Does It Translate to Better Outcomes?
Bhattacharya, A, Shen, B, Regueiro, M
Gastrointestinal endoscopy clinics of North America. 2019;(3):487-514
Abstract
This article discusses the use of endoscopy in patients with Crohn disease and ulcerative colitis in the postoperative setting. Endoscopy is the most sensitive and validated tool available in the diagnosis of recurrence of Crohn disease in the postoperative setting. It is also the most effective diagnostic modality available for evaluating complications of pouch anatomy in patients with ulcerative colitis. In addition to diagnosis, management postoperatively can be determined through endoscopy.

Diagnostic and therapeutic challenges of gastrointestinal angiodysplasias: A critical review and view points.
García-Compeán, D, Del Cueto-Aguilera, ÁN, Jiménez-Rodríguez, AR, González-González, JA, Maldonado-Garza, HJ
World journal of gastroenterology. 2019;(21):2549-2564
Abstract
Gastrointestinal angiodysplasias (GIADs), also called angioectasias, are the most frequent vascular lesions. Its precise prevalence is unknown since most of them are asymptomatic. However, the incidence may be increasing since GIADs affect individuals aged more than 60 years and population life expectancy is globally increasing worldwide. They are responsible of about 5% to 10% of all gastrointestinal bleeding (GIB) cases. Most GIADs are placed in small bowel, where are the cause of 50 to 60% of obscure GIB diagnosed with video capsule endoscopy. They may be the cause of fatal severe bleeding episodes; nevertheless, recurrent overt or occult bleeding episodes requiring repeated expensive treatments and disturbing patient's quality-of-life are more frequently observed. Diagnosis and treatment of GIADs (particularly those placed in small bowel) are a great challenge due to insidious disease behavior, inaccessibility to affected sites and limitations of available diagnostic procedures. Hemorrhagic causality out of the actively bleeding lesions detected by diagnostic procedures may be difficult to establish. No treatment guidelines are currently available, so there is a high variability in the management of these patients. In this review, the epidemiology and pathophysiology of GIADs and the status in the diagnosis and treatment, with special emphasis on small bowel angiodysplasias based on multiple publications, are critically discussed. In addition, a classification of GIADs based on their endoscopic characteristics is proposed. Finally, some aspects that need to be clarified in future research studies are highlighted.

Endoscopic Therapies for Gastroparesis.
Su, A, Conklin, JL, Sedarat, A
Current gastroenterology reports. 2018;(6):25
Abstract
PURPOSE OF REVIEW Gastroparesis remains a difficult-to-treat disease with limited therapeutic options. Though patients often have a common syndrome of stereotypic symptoms, the underlying pathophysiology is heterogeneous, often leading to variable treatment responses. Due to limitations in medical and surgical therapies, endoscopic options have been increasingly explored. These options can be broadly categorized into pyloric-directed therapy, non-pyloric-directed therapy, and nutritional support. In this review, we will highlight current and emerging endoscopic options, such as gastric per-oral endoscopic myotomy (G-POEM). RECENT FINDINGS Early retrospective studies on G-POEM offer encouraging results up to one year out, with an acceptable safety profile. Other pyloric-directed therapies, such as pyloric dilation and stenting, have also been explored. While emerging endoscopic therapeutic options are encouraging, efficacy will likely depend on a better characterization of underlying pathophysiology and improved patient selection. Future prospective, controlled studies are needed.

Performance of the over-the-scope clip system in the endoscopic closure of iatrogenic gastrointestinal perforations and post-surgical leaks and fistulas.
Iabichino, G, Eusebi, LH, Palamara, MA, Arena, M, Pellicano, R, Consolo, P, Fagoonee, S, Amato, L, Opocher, E, Barabino, M, et al

Abstract
The increased invasiveness of endoscopic procedures and complex surgical interventions has resulted in an increased number of gastrointestinal iatrogenic defects, such as perforations, leak and fistulas. The conventional treatment for these gastrointestinal defects is surgery, with considerable risks especially in emergency situations and in patients with comorbidities. The Ovesco over-the-scope clip (OTSC) system (Ovesco Endoscopy AG, Tübingen, Germany) and more recently, the Padlock Clip™ (Aponos Medical, Kingston, NH, USA) have shown promising results in the treatment of gastrointestinal defects. Several case reports and case series have demonstrated the efficacy of the OTSC system for the closure of full-thickness defects. Clinical success is best achieved in patients undergoing closure of a perforation or a leak. Closure of fistulas remains a clinical challenge since fibrosis or necrotic and inflamed tissue surrounding lesions may cause clip failure. Over-the-scope clips are a less invasive endoscopic option for managing patients with gastrointestinal defects before a more invasive surgical approach is attempted. Moreover, a failed attempt of OTSC deployment does not preclude subsequent surgical treatment.

Novel Nonsurgical Endoscopic Approaches for the Treatment of Obesity.
Hurt, RT, Frazier, TH, Mundi, MS
Nutrition in clinical practice : official publication of the American Society for Parenteral and Enteral Nutrition. 2017;(4):493-501
Abstract
Globally, obesity is a leading cause of preventable death and is associated with >60 comorbid medical conditions, including 10 types of cancer that are strongly associated with body mass index. There are a number of traditional obesity treatments-for example, lifestyle management (eg, decreased caloric intake and increased expenditure), pharmacotherapy, and bariatric surgery. Recently, endoscopic approaches have emerged as a viable alternative for weight loss. Endoscopically placed intragastric balloons were introduced in the early 1980s for the treatment of medically complicated obesity but, unfortunately, had high rates of complications, such as premature deflation leading to obstruction. Despite these shortcomings, these devices have experienced a renewal, with a second generation of improved devices being approved for clinical use in 2015. In addition to the intragastric balloons, there are a number of other endoscopic approaches to weight loss that are either Food and Drug Administration approved or undergoing evaluation (aspiration therapy, duodenal jejunal bypass sleeve). The current review examines the literature available and discusses the practical clinical considerations involved.

Sedation and Monitoring in the Pediatric Patient during Gastrointestinal Endoscopy.
Chung, HK, Lightdale, JR
Gastrointestinal endoscopy clinics of North America. 2016;(3):507-25
Abstract
Sedation is a fundamental component of pediatric gastrointestinal procedures. The 2 main types of sedation for pediatric endoscopy remain general anesthesia and procedural sedation. Although anesthesiologist-administered sedation protocols are more common, there is no ideal regimen for endoscopy in children. This article discusses specific levels of sedation for endoscopy as well as various regimens that can be used to achieve each. Risks and considerations that may be specific to performing gastrointestinal procedures in children are reviewed. Finally, potential future directions for sedation and monitoring that may change the practice of pediatric gastroenterology and ultimately patient outcomes are examined.

Endoscopic Evaluation and Management of the Postoperative Crohn's Disease Patient.
Hashash, JG, Binion, DG
Gastrointestinal endoscopy clinics of North America. 2016;(4):679-92
Abstract
Approximately 70% of patients with Crohn's disease (CD) undergo surgical resection for the treatment of medically refractory disease or its complications. The sickest cohort of CD patients experience rapid postoperative relapse at the anastomotic site. Over the past 2 decades, the types of surgical anastomoses used in CD reconstruction have changed; end-to-side and end-to-end anastomoses have been surpassed by the more rapidly created side-to-side anastomoses. This article provides a review of the timing and purpose of endoscopic evaluation in postoperative CD patients and pragmatic information regarding interpretation of endoscopic findings at the different types of surgical anastomoses after ileocecal resection.

Training for advanced endoscopic procedures.
Feurer, ME, Draganov, PV
Best practice & research. Clinical gastroenterology. 2016;(3):397-408
Abstract
Advanced endoscopy has evolved from diagnostic ERCP to an ever-increasing array of therapeutic procedures including EUS with FNA, ablative therapies, deep enteroscopy, luminal stenting, endoscopic suturing and endoscopic mucosal resection among others. As these procedures have become increasingly more complex, the risk of potential complications has also risen. Training in advanced endoscopy involves more than obtaining a minimum number of therapeutic procedures. The means of assessing a trainee's competence level and ability to practice independently continues to be a matter of debate. The use of quality indicators to measure performance levels may be beneficial as more advanced techniques and procedures become available.
