Abstract
INTRODUCTION: Pancreatic and gastric heterotopias are a rare presentation of pancreatic and gastric tissues located outside their expected location. The most common site of heterotopic pancreas is the gastric antrum, and the most common site of heterotopic gastric mucosa is the proximal esophagus. The two tissues rarely present simultaneously. Although lead-point intussusception secondary to simultaneous heterotypic gastric and pancreatic tissue is extremely rare, its management strategy is the same as other pathological lead-point intussusception. CASE DESCRIPTION: This report presents a 23-year-old female who presented to the emergency department with abdominal pain, vomiting, and gastrointestinal bleeding. Computed tomography scan revealed features of distal small bowel intussusception secondary to a solid mass lead point. Following laparoscopic assisted small bowel resection and incidental appendectomy, histopathology evaluation confirmed the diagnosis of heterotopic pancreatic and gastric tissue as the lead point. The patient had an uneventful postoperative period and was discharged in stable condition, free of symptoms. DISCUSSION: Lead point intussusception of the jejunum in adults due to combined heterotopic tissue is extremely rare, with no reported cases in the literature. Prompt diagnosis and management are essential, with delays in treatments leading to a risk of perforation and mortality. If diagnosed, minimally invasive surgical approaches can treat obstruction and improve intraoperative and postoperative outcomes.
