Diagnostic dilemma in gastroduodenal lesions: Heterotopic pancreas mimicking gastrointestinal stromal tumours managed by minimally invasive approach – A case series and review of the literature

HP should be considered in submucosal or intramural GI lesions, especially when mimicking GISTs or showing umbilication on endoscopy. Surgical resection is recommended for the symptomatic cases or diagnostic uncertainty, with minimally invasive approaches preferred. Our series highlights the first robotic excision of duodenal HP in the literature.
