In the current study, the publication rate and the number of subsequent citations of these thesis-derived papers were both low, and thus, the contribution of these animal studies to scientific progress is doubtful. It is recommended that institutional research ethics committees should be much more highly selective in approving the use of animals for the purposes of student thesis preparation.Device-assisted enteroscopy is currently lacking a validated training model, in contrast to the other major technique used for the study of the small bowel, namely capsule endoscopy. Training should be based on defining and achieving competency for the acquisition of the knowledge and skills required to perform enteroscopy in a safe and effective manner. The need for training is clear, since the technique is considered an advanced endoscopy form that requires maneuvers that differ from the usual ones that must be learned, in addition to specific equipment. Therefore, the ideal candidates for this training include professionals with accredited experience in therapeutic digestive endoscopy. Amongst the recommendations issued regarding device-assisted enteroscopy training, the estimation of small-bowel insertion depth and the choice of the examination route, whether oral or anal, should be highlighted. Learning curve descriptions have the limitation of being explorer-dependent with no consensus on the parameter that should be selected to establish a correct learning curve in enteroscopy. GSK795 The most commonly used parameter is insertion depth. The few training models that have been proposed recommend using a highly useful tool, namely simulators and to start practicing under expert guidance. Based on the variability of published data, an experienced endoscopist may perform enteroscopy in a safe and effective manner after 5 to 35 training procedures. Although reaching the expert level requires prolonged clinical practice with exposure to the various disorders of the small bowel.INTRODUCTION studies have examined the agreement between capsule endoscopy and double-balloon enteroscopy, with varying results. The aim of this study was to identify factors that predict the visualization of lesions in the small bowel by double-balloon enteroscopy after a positive capsule endoscopy. METHODS a retrospective, observational and comparative study was performed that evaluated patients that underwent double-balloon enteroscopy after a positive capsule endoscopy, between January 2017 and August 2019. The data studied included demographics, indications, comorbidities and the results of capsule endoscopy and double-balloon enteroscopy, which were evaluated by multiple logistic regression. RESULTS 91 patients were included (age 58 ± 16.5 years, 53 female). Sixty-two double-balloon enteroscopy (68.1 %) found the same lesions as capsule endoscopy. Predictive factors for a positive double-balloon enteroscopy were multiple lesions (OR 8.10, 1.50-43.78; p = 0.015) and 60 years of age (OR 7.45, 1.51-36.75; p = 0.014) and ulcers (OR 4.67, 1.08-20.22; p = 0.039). CONCLUSIONS predictive factors for a positive double-balloon enteroscopy after a positive capsule endoscopy were multiple lesions and less then 15 days between both procedures. In patients with small bowel bleeding, age over 60 years and the presence of ulcers were also predictive factors.INTRODUCTION the aim of this study was to determine the risk factors for rebleeding following device-assisted enteroscopy therapy of small bowel vascular lesions. METHODS this is a systematic review and meta-analysis. A literature search was performed from January 2003 to October 2019. All studies reporting on at least one risk factor for bleeding recurrence after endoscopic therapy of small bowel vascular lesions were included. A meta-analysis of those risk factors reported in at least three studies was performed to assess their association with rebleeding. The OR and 95 % CI were used for binary outcome data. Heterogeneity analysis was performed using the Tau and I2 index. If I2 > 20 %, potential sources of heterogeneity were identified by sensitivity analyses and a random-effect model was used. RESULTS the search identified a total of 572 articles and 35 full-text records were assessed for eligibility after screening. Finally, eight studies that included 548 patients were selected. The overall median rebleeding rate was 38.5 % (range 10.9-53.3 %) with a median follow-up of 24.5 months. Female sex (OR 1.96, 95 % CI 1.14-3.37, p = 0.01, I2 = 0 %), Osler-Weber syndrome (OR 4.35, 95 % CI 1.22-15.45, p = 0.02, I2 = 0 %) and cardiac disease (OR 1.89, 95 % CI 1.12-2.97, p = 0.005, I2 0 %) were associated with rebleeding. According to the sensitivity analysis, overt bleeding (OR 2.13, 95 % CI 1.22-3.70, p = 0.007, I2 = 0 %), multiple lesions (OR 4.57, 95 % CI 2.04-10.22, p less then 0.001, I2 = 0 %) and liver cirrhosis (OR 2.61, 95 % CI 1.11-6.13, p = 0.03, I2 = 0 %) were also predictors for rebleeding. CONCLUSIONS patient characteristics and comorbidities should be considered for follow-up patient management after effective device-assisted endoscopic therapy, as they can predict rebleeding.INTRODUCTION Dieulafoy's lesion of the small bowel is an uncommon cause of gastrointestinal (GI) bleeding that often recurs after endoscopic treatment. MATERIAL AND METHODS we report an observational, descriptive, retrospective, single-center study in 15 patients with small bowel bleeding who were diagnosed with a Dieulafoy's lesion by capsule endoscopy or double-balloon enteroscopy. RESULTS AND CONCLUSIONS all patients underwent combined endoscopic treatment. During a median follow-up of 33.5 months (range, 2-145), three of the 12 cases that stayed in follow-up (25 %) recurred, all within 48 hours after treatment. Two were successfully re-treated with a repeat endoscopic procedure.Within the project "Quality Indicators in Gastrointestinal Endoscopy," under the leadership of the Sociedad Española de Patología Digestiva (SEPD), our goal is to propose the procedures and the structure, process, and outcome indicators required for the application and assessment of quality in enteroscopy. To this end a search was performed for quality indicators in enteroscopy. Quality of evidence was measured by using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system, and classified as high, moderate, low, and very low. A total of 10 process indicators (one preprocedure, eight procedure, one postprocedure) were identified for enteroscopy, with appropriate indication and choice of most efficient route being most significant.
