Multicenter StudyDiagnosis and treatment of small-bowel stricture by double balloon endoscopy.
The source of small-bowel stricture is often difficult to diagnose due to the difficulty of placing an endoscope into the small bowel. It has recently become possible to examine the entire small bowel and perform balloon dilatation for stricture by means of double balloon endoscopy (DBE). ⋯ DBE appears to be useful for the detection as well as treatment of small-bowel lesions.

Randomized Controlled Trial Multicenter Study Clinical TrialPremedication with orally administered midazolam in adults undergoing diagnostic upper endoscopy: a double-blind placebo-controlled randomized trial.
A double-blind placebo-controlled randomized trial was conducted to investigate the safety and the efficacy of orally administered midazolam as premedication for patients undergoing elective EGD. ⋯ Premedication by oral administration of midazolam is a safe and an effective method of sedation that significantly reduces anxiety and improves overall tolerance for patients undergoing EGD.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialUrgent vs. elective endoscopy for acute non-variceal upper-GI bleeding: an effectiveness study.
Urgent endoscopy in patients with acute upper-GI bleeding identifies many patients who may be safely treated without hospitalization. The aim of this multicenter trial was to determine whether urgent endoscopy effectively decreases health care resource utilization in a real-life setting where primary care providers determine the course of care. ⋯ Urgent endoscopy did not reduce hospitalization or resource utilization because the results of early endoscopy did not impact the decision by attending physicians regarding admission. For early (triage) endoscopy to impact resource utilization, the results of endoscopy must change subsequent patient care.

Multicenter StudyEUS-guided fine needle aspiration in mediastinal lymphadenopathy of unknown etiology.
EUS-guided fine needle aspiration (EUS-FNA) has significantly expanded the diagnostic capability of GI EUS. FNA technology can also be helpful in the diagnosis of non-GI disorders. The role of EUS-guided FNA in the diagnosis of mediastinal lymphadenopathy of unknown etiology has not been described. The aim of this study was to evaluate the diagnostic accuracy and impact on subsequent evaluation and therapy of EUS-FNA in mediastinal lymphadenopathy of unknown cause. ⋯ EUS-FNA in patients with mediastinal lymphadenopathy is safe and guides subsequent therapy in the great majority of cases. Transesophageal EUS-FNA of mediastinal lymph nodes provides minimally invasive tissue sampling, obviating the need for mediastinoscopy or bronchoscopy.

Multicenter StudyEffectiveness of endoscopy in patients admitted to the intensive care unit with upper GI hemorrhage.
Esophagogastroduodenoscopy (EGD) is generally indicated for the management of patients admitted to intensive care units (ICUs) with upper gastrointestinal (GI) hemorrhage but its impact in community practice has not been measured. Thus, the effectiveness of 3 EGD factors, viz., accurate initial diagnosis, performance within 24 hours of admission (early EGD), and appropriate intervention, was examined. ⋯ Early, accurate EGD with appropriate therapeutic intervention is effective as practiced in the community and is associated with improved outcomes for patients with upper GI hemorrhage admitted to the ICU. Inaccurate diagnosis at initial EGD is uncommon but has a significant adverse association with all outcome measures.
