Transnasal endoscopic placement of feeding tubes in the intensive care unit

Abstract

BACKGROUND: There is an increasing demand for enteral feeding in intensive care unit (ICU) patients. However, gastroparesis is common, and jejunal placement with gastric decompression leads to delays in feeding. In an attempt to minimize delays, we describe our technique and results with transnasal endoscopic placement of double-lumen gastric aspiration, jejunal feeding tubes (DLFT). METHODS: Fifty-one consecutive ICU patients referred for nutrition support were studied; 29% had respiratory failure, 28% acute head injury, and 33% acute pancreatitis. A 5.8-mm ultraslim video endoscope was used to place a guidewire through the nose terminating beyond the Ligament of Treitz. After withdrawal of the endoscope, a DLFT was passed over the wire. Final position of the tube was checked and adjusted under direct vision by reendoscopy though the opposite nasal passage. RESULTS: Initial placement of the guidewire and DLFT was successful in 46 of 51 patients. Massive gastric dilatation and acute pancreatitis complicated by duodenal compression impeded full duodenoscopy in 5 patients, necessitating fluoroscopy for correct guidewire deployment. In confirming correct tube placement, there was near perfect concordance between reendoscopy and x-ray (45/46). Previously unrecognized upper gastrointestinal tract pathology was detected in most patients, with acute gastritis in 47, superficial gastric ulceration in 24, and erosive esophagitis in 5. CONCLUSIONS: Transnasal endoscopic placement of feeding tubes in the ICU is quick, effective, and minimally disruptive of intensive therapy. In addition, it can reveal unrecognized pathology, which potentially could lead to improvements in overall medical care.

Double-lumen gastric decompression/jejunal feeding tube placement was successful in the initial attempt in 51 consecutive medical and neuroscience intensive care unit patients. Fluoroscopic guidance may be needed in patients with gastric dilatation and duodenal compression.
