We present a case of an ectopic stomach visualized intraoperatively at the site of intestinal intussusception via surgeon-assisted advancement of the endoscope. Heterotopic gastric mucosa, also known as an ectopic stomach, refers to the discovery of gastric tissues in an organ or tissue distinct from, and without vascular or anatomical continuity with, the main body of the normal stomach. In our case, an 18-year-old woman presented to the emergency department with jejunal intussusception. During emergency laparotomy, a large pedunculated mass was visualized and later confirmed histopathologically to be an ectopic stomach.
