Abstract
From June 2017 to September 2019, 5 patients who were diagnosed as having benign severe pyloric stenosis underwent fully covered stent placement using a new stenting method at the First Affiliated Hospital of Zhengzhou University. Five patients were performed successfully without serious complications. Postoperative barium meal radiograph revealed that the stents were in good location and the acontrast agent passed smoothly. The liquid diet was commenced 1-3 days after surgery. No vomiting, abdominal pain and diarrhea occurred. During the follow-up, all the patients had improved weight and nutritional status. Four patients underwent stent removal 3-4 months postoperatively. One patient was found that the stent had migrated to stomach 3 months after discharge. After removing the stent, balloon dilation and mucosal resection was performed for the mild pyloric stenosis. All 5 patients had an additional follow-up of 3 months, and no symptoms and restenosis occured. These preliminary results showed that the new stenting method of fully covered stent placement is feasible, safe and effective in the treatment of benign pyloric stenosis.
