Retrograde jejuno-gastric intussusception is a rare complication following gastric surgery. We present a case of retrograde jejuno-gastric intussusception in a 42-year-old female who presented with upper abdominal pain, vomiting and swelling in left hypochondruim. Intussusception was suspected on ultrasound of the abdomen and later confirmed with computed tomography scan. At laparotomy, efferent loop was intussuscepting into stomach. This was reduced and fixed to the abdominal wall and transverse mesocolon. It should be suspected in a patient with the previous history of gastric surgery as it is a rare complication. Early diagnosis and management can prevent further complications like bowel gangrene and its associated morbidity and mortality.
