| titleOfInvention | An improved method for retrieving pancreatic juice utilizing an endoscopically wire-guided catheter |
| abstract | This invention is a method for accurately and quickly positioning a double lumen gastroduodenal tube (402) into predetermined locations utilizing an endoscopically placed guidewire (202) to retrieve duodenal fluid uncontaminated by gastric fluid, with little or no discomfort to the patient, and minimal radiation exposure. Specifically, an endoscope (112) is passed through a patient's esophagus and stomach (104) into the duodenum (108) such that its distal end is located at a predetermined location, such as the fourth portion of the duodenum. While the endoscope (112) is held in place, a guidewire (202) is passed through its center instrument channel to position a distal end of the guidewire (202) adjacent to the distal end of the endoscope (112). The endoscope (112) is then withdrawn from the patient, leaving the guidewire (202). A double lumen gastroduodenal tube (402) is then threaded over the guidewire (202) such that gastric ports (412) are aligned with the stomach (104) and duodenum so that upon aspiration of the gastric ports, the gastric fluid is prevented from entering the duodenum and contaminating the duodenal fluid. |
