Objective :to study the percutaneous endoscopic jejunostomy applied in postoperative gastric cancer patients of gastric emptying disorder phe-nomenon when the clinical curative effect .Methods :23 cases of gastric cancer patients with postoperative gastric emptying disorder as the research object ,by local anesthesia or basic anesthesia are made under the condition of percutaneous endoscopic jejunostomy treatment ,all patients with postoperative gastric decompression and enteral nutrition support and intervention measures .Results :23 cases of patients with operation were successful ,the average operation time was (19 .23 ± 4 .41) min ,and did not find any complications associated with the catheter ,prognosis is good .2 d postoperative nutritional support to all of the patients using jejunum nutrition tube ,the average (7 .28 ± 1 .58) after d completely out of parenteral nutrition ;Postoperative gastric dynamic GaBi the drainage tube ,the average time was (19 .37 ± 7 .71) d indwelling time averaged (35 .73 ± 11 .72) d ,all of the patients during drawing tube body health and nutrition absorb good condition compared with the preoperative ,to improve the situation .Conclusion:percutaneous endoscopic jejunostomy applied in postoperative gastric cancer cured by clinical treatment ,can produce ideal gastric decompression and the effect of nutritional support ,clinical signs ,the health of patients and quality of life have different degrees of improvement ,worthy of clinical application and promotion .%目的：探讨经皮内镜下空肠造口术应用于胃癌患者术后产生胃排空障碍现象时的临床疗效。方法：选取23例胃癌术后发生胃排空障碍的患者作为本次的研究对象，通过局部麻醉或基础麻醉的情况下均采用经皮内镜下空肠造口术进行治疗，所有患者术后予以胃减压以及肠内营养支持等干预措施。结果：23例患者手术均获得成功，平均手术时间为（19．23±4．41）min ，且未发现与导管相关的任何并发症，预后较好；术后第2d对所有患者采用空肠营养管予以营养支持，平均（7．28±1．58）d后完全脱离肠外营养；术后胃动力夹闭胃引流管平均时间为（19．37±7．71）d ，留置时间平均为（35．73±11．72） d，所有患者在拔管时的身体健康状况以及营养汲取状况与术前相比较好，改善情况理想。结论：经皮内镜下空肠造口术应用于胃癌术后排空障碍的临床治疗当中，能够产生较为理想的胃减压以及营养支持效果，对患者的临床体征、健康状况以及生活质量均有不同程度的明显改善，值得临床应用及推广。
