Technical success rate and safety of radiologically inserted gastrostomy versus percutaneous endoscopic gastrostomy in motor neuron disease patients undergoing: A systematic review and meta-analysis.

Objective: Percutaneous endoscopic gastrostomy (PEG) and radiologically inserted gastrostomy (RIG) have gained increasing popularity among clinicians and motor neuron disease (MND) patients for maintaining adequate nutritional intake. However, there is no consistent evidence of the efficacy and safety of the two techniques in MND patients. We carried out a systematic review and meta-analysis to examine the technical success rates, complication rates and 30-day mortality of MND patients receiving PEG and RIG.

Silicone-covered biodegradable magnesium stent for treating benign esophageal stricture in a rabbit model.

Background: Stent insertion can effective alleviate the symptoms of benign esophageal strictures (BES). Magnesium alloy stents are a good candidate because of biological safety, but show a poor corrosion resistance and a quick loss of mechanical support .

Aim: To test the therapeutic and adverse effects of a silicone-covered magnesium alloy biodegradable esophageal stent.
