Summary
Percutaneous endoscopic gastrojejunostomy (PEGJ) placement is feasible and safe in patients with situs inversus (SI), a rare condition causing organ mirror-image reversal. Careful planning and adaptive techniques ensure procedural success for essential enteral nutrition.
Area of Science:
- Gastroenterology
- Medical Case Reports
- Congenital Disorders
Background:
- Situs inversus (SI) is a rare congenital disorder with complete mirror-image reversal of thoracoabdominal organs.
- Percutaneous endoscopic gastrostomy with jejunal extension (PEGJ) is vital for postpyloric enteral nutrition.
- PEGJ in SI patients has not been previously documented.
