Introduction:
Jejunogastric intussusception (JGI) is an extremely rare complication of prior gastric surgery. Fewer than 200 cases have been reported in the literature.
Case presentation:
We present a case of an elderly male who presented with typical abdominal pain, hematemesis and a palpable epigastric mass. Ultrasonography and upper endoscopy diagnosed jejunogastric intussusception. Emergent laparotomy with manual reduction of the efferent loop intussusception resulted in successful treatment.
Discussion:
We report this case of efferent loop JGI, developing 40 years after the primary Billroth II gastrectomy. This is the longest interval from the initial gastric surgery for gastric cancer to be reported.
Conclusion:
Maintaining a high index of suspicion is paramount in early diagnosis and treatment of this condition, which is associated with high mortality rates if surgery is delayed.
