Multicenter Study Comparative StudyEndosonographic features predictive of malignancy in mediastinal lymph nodes in patients with lung cancer.
EUS is useful in determining mediastinal lymph node (LN) metastases in patients undergoing staging for lung cancer. However, FNA of LNs is often performed only if suspicious features are present. The utility of individual LN features in predicting malignant cytology remains unclear. ⋯ Among patients with lung cancer, EUS features of round shape, sharp margins, and short axis of >8.3 mm are significant predictors of malignancy. The probability of malignancy is low when none of the features are present.

Randomized Controlled Trial Multicenter Study Comparative StudyTraining and transfer of colonoscopy skills: a multinational, randomized, blinded, controlled trial of simulator versus bedside training.
The Olympus colonoscopy simulator provides a high-fidelity training platform designed to develop knowledge and skills in colonoscopy. It has the potential to shorten the learning process to competency. ⋯ Performance of novices trained on the colonoscopy simulator matched the performance of those with standard patient-based colonoscopy training, and novices in the simulator group demonstrated superior technical skills on simulated cases. The simulator should be considered as a tool for developing knowledge and skills prior to clinical practice.

Multicenter StudyTherapeutic outcomes in 1000 cases of endoscopic submucosal dissection for early gastric neoplasms: Korean ESD Study Group multicenter study.
The technique of endoscopic submucosal dissection (ESD) was introduced to be able to obtain en bloc specimens of large early GI neoplasms. The drawback of ESD is its technical difficulty, which, consequently, is associated with a higher rate of complication and which requires advanced endoscopic techniques and a long procedure time. ⋯ ESD is an effective and safe therapy in the management of early gastric neoplasms. Endoscopists have to accept the need for advanced endoscopic techniques for performing ESD in the case of large lesions, scar lesions, undifferentiated cancers, or for the lesions in the upper portion of the stomach. Endoscopists require more experience to decrease complications in patients who have a large or recurrent lesion in the upper portion of the stomach; these lesions also take more time to complete the ESD procedure.

Multicenter Study Comparative StudyCaustic ingestion in children: is endoscopy always indicated? The results of an Italian multicenter observational study.
The ingestion of caustic substances can represent a serious medical problem in children. ⋯ The results demonstrated that the incidence of patients with third-degree lesions without any early symptoms and/or signs is very low, and an endoscopy could be avoided. The risk of severe damage increases proportionally with the number of signs and symptoms, and an endoscopy is always mandatory in symptomatic patients.
