Successful resection of a gastric aberrant pancreas causing gastrointestinal bleeding by laparoscopy and endoscopy cooperative surgery

: A man in his 50s was admitted to our hospital for treatment of hematemesis. Endoscopy revealed arterial bleeding from a gastric submucosal tumor and endoscopic hemostasis was successful. However, surgical resection was contemplated to prevent recurrent bleeding and for making a definitive diagnosis. Surgical resection was eventually performed by laparoscopy and endoscopy cooperative surgery (LECS), and the tumor was pathologically diagnosed to be a gastric aberrant pancreas. We think that LECS is suitable for a gastric aberrant pancreas causing gastrointestinal bleeding, because the procedure is effective for tumor resection with minimal removal of the stomach wall.
