Ectopic pancreas induced ileocecal intussusception: A rare case report.

Introduction and importance: Ectopic pancreas is not uncommon, but ileocecal intussusception caused by ectopic pancreas is extremely rare. Thus far, only approximately 10 cases have been reported. Case presentation: Herein, we report a 47-year-old male who presented with abdominal distension and discomfort without apparent cause, accompanied by nausea but no vomiting or other symptoms. The patient's vital signs were stable, and examination revealed increased bowel sounds, tympanic percussion of the abdomen, and tenderness in the lower right abdomen. After laparoscopic exploration, an irreducible intestinal obstruction was found, which subsequently required open surgery. Pathological examination of the resected portion revealed that the patient's ileocecal intussusception was caused by ectopic pancreas. Clinical discussion: Prior to receiving the pathological report, we were not aware that the patient's abdominal pain may have been attributed to ileocecal intussusception induced by ectopic pancreas. This posed challenges in diagnosis and treatment, underscoring the importance of raising awareness among our colleagues through this case report. Conclusion: Our findings emphasize the need to consider the possibility of abdominal pain caused by ileocecal intussusception induced by ectopic pancreas during the investigation of abdominal pain.
