Gastrogastric Intussusception: A Rare Complication of Hiatal Hernias

Gastrogastric intussusception (GGI) is a rare and potentially serious condition in adults that presents with symptoms of acute abdominal pain, nausea, and vomiting. We report a case of GGI in a 58-year-old woman presenting with sudden-onset lower abdominal pain, nausea, vomiting, and constipation. She underwent a diagnostic and therapeutic endoscopic examination and was found to have a type I hiatal hernia complicated by intussusception, which was successfully reduced via insufflation and gentle pressure. Further evaluation revealed a hiatal hernia as the potential lead point, a rare occurrence in cases of adult intussusception.
