Effectiveness of a Novel Covered Stent without External Thread Fixation for Anastomotic Leakage after Total or Proximal Gastrectomy for Gastric Cancer

A thread-fix stent entails long hospitalization and patient discomfort. We aimed to evaluate the efficacy of a novel stent with silicone-covered outer double layers without external fixation (Beta stent) for anastomotic leakage after total or proximal gastrectomy. The outcomes were compared between gastric cancer patients who underwent stent placement using a thread-fix stent between 2014 and 2015 (Thread-Fix Group) and those who received a Beta...
