To evaluate the utility of ultrasound (US) guidance in the percutaneous placement of gastric feeding tubes in patients in whom placement of a nasogastric tube is not possible.
Records from feeding tube placements performed between January 1991 and August 1994 were reviewed. Of the 238 procedures performed, 27 cases (11%) involved initial US guidance, rather than nasogastric tube assistance, because of upper gastrointestinal obstruction.
US allowed rapid puncture and subsequent insufflation of the stomach in 26 of the 27 patients, and there were no complications related to its use. In the other patient the position of the transverse colon prevented suitable visualization for puncture, and surgical placement of the feeding tube was necessary.
US guidance is a safe and effective means by which the stomach can be punctured and distended before placement of a percutaneous feeding tube for patients in whom nasogastric intubation is not possible.
评估超声（US）引导在无法放置鼻胃管的患者经皮放置胃饲管中的效用。
回顾了1991年1月至1994年8月期间进行的饲管放置记录。在238例操作中，27例（11%）因上消化道梗阻，最初采用超声引导而非鼻胃管辅助。
27例患者中的26例，超声引导下可快速穿刺并随后向胃内注入气体，且未出现与超声使用相关的并发症。另一例患者中，横结肠位置妨碍了合适的穿刺视野，因此需要通过手术放置饲管。
对于无法进行鼻胃插管的患者，超声引导是一种安全有效的方法，可在经皮放置饲管前对胃进行穿刺和扩张。
