Rapid duodenal and jejunal intubation.

Area of Science:

• Gastroenterology
• Medical Devices
• Radiology

Background:

• Duodenal and jejunal intubation are crucial for diagnostic and therapeutic procedures.
• Existing methods for intubation can be challenging and time-consuming.

Purpose of the Study:

• To describe a novel size 12 French radiopaque catheter designed for efficient duodenal and jejunal intubation.
• To highlight the catheter's suitability for barium infusion and hypotonic duodenography.

Main Methods:

• A 135 cm long, flexible, radiopaque catheter was utilized.
• A guide wire was employed as a stiffener during passage through the stomach.
• The technique for nasal passage, stomach, and duodenal intubation was detailed.

Main Results:

• The catheter's size and flexibility allow for easy passage through the upper gastrointestinal tract.
• The guide wire effectively stiffened the catheter for gastric passage.
• The device proved suitable for direct barium infusion into the small intestine.

Conclusions:

• The described catheter offers a simplified and effective method for duodenal and jejunal intubation.
• This device enhances the performance of barium infusion and hypotonic duodenography.
• The technique discussed facilitates easier gastrointestinal procedures.
