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 Comparative StudyA prospective, randomized, comparative trial evaluating respiratory depression during patient-controlled versus anesthesiologist-administered propofol-remifentanil sedation for elective colonoscopy.
Patient-controlled sedation (PCS) with propofol-remifentanil (PR) is associated with rapid sedation and recovery, but it is associated with a greater requirement for airway rescue than PCS with midazolam-fentanyl. ⋯ NCT00868920.).

Randomized Controlled Trial Comparative StudyCovered versus uncovered self-expandable metallic stents for palliation of malignant pyloric obstruction in gastric cancer patients: a randomized, prospective study.
Self-expandable metallic stents (SEMSs) provide effective palliation of malignant pyloric obstruction in patients with inoperable gastric cancer. ⋯ Both the covered and uncovered SEMSs are effective and have comparable 8-week patency in patients with malignant pyloric obstruction, despite different patterns of late stent failure.

Randomized Controlled Trial Comparative StudyEfficacy of computed virtual chromoendoscopy on colorectal cancer screening: a prospective, randomized, back-to-back trial of Fuji Intelligent Color Enhancement versus conventional colonoscopy to compare adenoma miss rates.
Colonoscopy is the criterion standard for screening of colorectal neoplasms. Nonetheless, a substantial miss rate with conventional, white-light colonoscopy (WL) remains a challenge. ⋯ FICE at screening colonoscopy did not improve the adenoma miss rate or detection rate compared with WL.
