In our pediatric interventional practice, we have found that occasionally a loop of bowel is interposed between the stomach and the anterior wall of the abdomen, preventing safe needle access for procedures such as placement of a gastrostomy tube. The use of a small-caliber needle to aspirate air from the colon or small bowel, for bowel decompression, may be a safe way to aid in establishing a safe access route for the subsequent percutaneous introduction of larger needles or tubes.
Our retrospective review of patients who have undergone bowel-gas aspiration during an interventional procedure shows that the aspiration of air from the colon with a small-caliber needle is technically easy and may permit completion of an abdominal procedure.
在我们的儿科介入治疗实践中，我们发现偶尔会有一段肠管夹在胃和腹壁之间，这使得诸如放置胃造瘘管等操作无法安全地进行穿刺。使用小口径针头从结肠或小肠抽吸气体以进行肠道减压，可能是一种安全的方法，有助于为随后经皮插入更大的针头或导管建立安全的穿刺路径。
我们对在介入治疗过程中进行肠气抽吸的患者进行的回顾性研究表明，用小口径针头从结肠抽吸气体在技术上很容易，并且可能使腹部手术得以完成。
