Abstract:
This case report describes an 83-year-old woman with multiple comorbidities who presented with melena and coffee-ground emesis with diagnostic studies evident for a large prepyloric gastrointestinal stromal tumor. She underwent combined laparoendoscopic transgastric resection surgery for the tumor, performed by a team of gastroenterologist and thoracic surgeon with a successful outcome. The case and videos in this report provide a descriptive demonstration of the steps leading up to the surgical intervention followed by a step-by-step illustration of the combined surgical technique, thus highlighting the importance of multidisciplinary approach for optimal treatment of prepyloric gastrointestinal stromal tumor.

Physiology of the Gastrointestinal System II: Digestion and Absorption
Digestion begins in the mouth, where food undergoes mechanical breakdown by chewing and combines with saliva. Salivary amylase, an enzyme in saliva, starts the breakdown of starches into maltose. The food then travels down the esophagus to the stomach.
In the stomach, a...
