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.

Comparative StudyCarbon dioxide versus room air for natural orifice transluminal endoscopic surgery (NOTES) and comparison with standard laparoscopic pneumoperitoneum.
Most studies investigating natural orifice transluminal endoscopic surgery (NOTES) have used room air, whereas carbon dioxide (CO(2)) is traditionally preferred for laparoscopic insufflation. ⋯ Pressure-controlled endoscopic insufflation of CO(2) for NOTES showed minor advantages compared with insufflation of room air regarding intra-abdominal visualization, but resulted in an increase in cardiac afterload. However, the cardiorespiratory responses during endoscopic insufflation of CO(2) were similar to the widely accepted standard laparoscopic CO(2) insufflation.
