Outcomes of secondary stent-in-stent self-expandable metal stent insertion for malignant colorectal obstruction.
Although self-expandable metal stents (SEMSs) are widely used for the treatment of malignant colorectal obstruction, they often become occluded by tumor ingrowth. ⋯ Secondary stent-in-stent SEMS placement led to good outcomes in patients with malignant colorectal obstruction, despite a slightly lower success rate compared with primary SEMS placement. Patency duration of the primary SEMS and carcinomatosis were important factors predictive of immediate and long-term clinical success of stent-in-stent insertion, respectively.

EditorialEndoscopic visceral fat removal as therapy for obesity and metabolic syndrome: a sham-controlled pilot study (with video).
Increased visceral adiposity is a key feature of obesity and metabolic syndrome. Previous studies have generated controversial results regarding visceral fat (VF) removal as a therapy for obesity and metabolic syndrome. ⋯ Endoscopic omentectomy is safe and feasible and has the potential to treat obesity and metabolic syndrome. Near-total VF removal is required to achieve net weight loss and improvement of metabolic syndrome.
