Malignant gastric outlet stenosis is caused by tumour obstruction and restricts the oral intake of food, resulting in a seriously reduced quality of life. Endoscopic implantation of self expanding metal stents (SEMS) can clear stenosis in the GI-tract and reestablish and preserve the passage in the GI-tract.
Between October 2001 and April 2003 seven patients with malignant gastric outlet stenosis have been treated by the implantation of SEMS. Four patients had malignant stenosis in the upper duodenum or gastric antrum, two patients had stenosis because of tumour recurrence in the efferent loop of the jejunum after gastric resection because of gastric carcinoma and one patient had an obstruction 20 cm distal of the oesophagus after gastrectomy because of gastric cancer.
In all patients obstruction was cleared by the implantation of SEMS, and oral intake of food was possible in all patients after two days. No serious complications occurred during or after stent implantation.
Stent implantation for the treatment of malignant gastric outlet stenosis is a cost effective procedure, associated with low risk and low stress for the patient, and provides excellent palliation of symptoms in patients with malignant gastric outlet stenosis.
恶性胃出口狭窄由肿瘤阻塞引起，限制食物经口摄入，导致生活质量严重下降。内镜下植入自膨式金属支架（SEMS）可解除胃肠道狭窄，重建并维持胃肠道通路。
2001年10月至2003年4月期间，7例恶性胃出口狭窄患者接受了SEMS植入治疗。4例患者存在十二指肠上段或胃窦部恶性狭窄，2例患者因胃癌胃切除术后空肠输出袢肿瘤复发导致狭窄，1例患者因胃癌胃切除术后食管远端20 cm处出现梗阻。
所有患者通过植入SEMS均解除了梗阻，术后两天所有患者均可经口进食。支架植入过程中及术后未发生严重并发症。
支架植入治疗恶性胃出口狭窄是一种性价比高的方法，对患者风险低、压力小，能有效缓解恶性胃出口狭窄患者的症状。
