Gastric duplication cyst in an adult: a rare case presentation and literature review.

Our paper reports an unusual case of a large gastric duplication cyst (GDC) and a concurrent hepatic cyst in a 50-year-old woman, who presented with severe epigastric pain, weight loss and early satiety. Multimodality imaging was performed before surgery. Laparoscopic resection was favoured but was converted to open due to extensive adhesions. The cyst was completely excised. Post-operative histopathological findings confirmed GDC with no atypia/ malignancy. Our case sheds light on the diagnostic, surgical and post-operative challenges, providing a learning opportunity into this rare entity. Finally, a comprehensive literature review also highlighted the various pathologies that GDC can often mimic.
