Abstract

The placement of gastrointestinal tubes into the gastric antrum and duodenum is facilitated by a simple technic which depends upon magnet-tipped tubes. The method is efficient at the bedside and in the examining room, without the need for roentgen confirmation; it is based upon the detection of a magnetic field which appears upon the skin within 6–10 cm of the magnet. Although sensitive electronic equipment may be used for measurement of these magnetic field projections, a small plotting compass serves well for clinical purposes and is more rapid. In 34 of 36 consecutive studies, the magnet-tipped tube was placed correctly into the gastric antrum, and the collection holes were positioned properly for quantitative gastric analysis. In 24 of 28 consecutive duodenal intubation studies, the magnet-tipped tube was placed correctly into a proper position for the collection of duodenal secretions. This simple method can be used to assure proper localization of various tubes in the stomach and duodenum.
