Magnetic balloon-assisted percutaneous endoscopic jejunostomy

Area of Science:

• Gastroenterology
• Minimally Invasive Surgery
• Medical Device Technology

Background:

• Percutaneous endoscopic jejunostomy (PEJ) is challenging in patients with altered anatomy.
• Obesity and prior Roux-en-Y gastric bypass complicate enteral feeding tube placement.
• Standard PEJ techniques may fail due to anatomical variations and adiposity.

Purpose of the Study:

• To describe the use of magnetic balloon technology for percutaneous endoscopic jejunostomy (PEJ) placement.
• To demonstrate a novel method for jejunal puncture point identification in difficult cases.
• To report a successful PEJ procedure using magnetic assistance without fluoroscopy.

Main Methods:

• Magnetic balloon technology was employed to anchor the jejunum to the abdominal wall.
• A ferromagnetic balloon and permanent magnet facilitated precise jejunal access.
• A 20F enteral feeding tube was inserted into the jejunal Roux limb.

Main Results:

• Magnetic balloon technology enabled precise identification of the jejunal puncture point.
• The PEJ procedure was successfully completed without the need for fluoroscopy.
• No adverse events were reported during or after the magnetic balloon-assisted PEJ placement.

Conclusions:

• Magnetic balloon technology offers a promising solution for challenging PEJ procedures.
• This technique may overcome the limitations of traditional jejunal access methods.
• Magnetic assistance can reduce the technical failure rate associated with PEJ placement.
