内镜支架置入新技术治疗幽门良性狭窄的初步观察（含视频）

2017年6月—2019年9月，5例良性重度幽门狭窄患者在郑州大学第一附属医院接受了内镜下全覆膜支架置入新技术治疗，5例均成功完成幽门处全覆膜支架置入，无并发症发生，术后行上消化道造影显示支架位置良好、造影剂通过顺利。5例患者于术后1～3 d开始进流食，进食后均无呕吐、腹痛、腹泻等症状出现，随访期间均有不同程度的体重增加，营养状态获得明显改善。4例于术后3～4个月行支架取出术；余1例于术后3个月发现支架移位至胃内，取出支架后观察幽门口略狭窄，行球囊扩张术+黏膜切开术。随后5例继续随访3个月，均无症状反复及再狭窄。以上结果初步证实，内镜下全覆膜支架置入新技术治疗良性幽门狭窄安全、有效。

Preliminary results of endoscopic stent placement for treating benign pyloric stenosis (with video)

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.
