Conclusion
In conclusion, a rare complication following classic gastric bypass
surgery is retrograde intussusception with a variety of presentations
including colicky abdominal pain , constipation ,nausea and vomiting
,and also upper gastrointestinal bleeding (hematemesis) just like our
case that can cause misdiagnosis during management. We believe that this
paper is the first jejunojejunal intussusception with hematemesis that
reported in the literature following classical gastric bypass surgery.
Clinicians should suspect the presence of intussusception after
bariatric surgery even with fresh upper gastrointestinal bleeding
presentation
