Abstract
We herein describe the rare case of a patient with a gastric duplication cyst who underwent laparoscopic resection. A 67-year-old man was referred to our hospital with an intra-abdominal lesion incidentally diagnosed on abdominal computed tomography. Esophagogastroduodenoscopy revealed normal esophageal and gastric mucosa without any lesions. Abdominal contrast-enhanced computed tomography revealed an 18 mm well-defined mass adjacent to the lesser curvature side of the esophagogastric junction. Following clinical diagnosis as an intra-abdominal mass, the patient underwent laparoscopic surgery in a five-port setting. The lesion originated from the stomach, near the muscular layer. The stomach muscle layer was partially resected; however, no communication between the mass and gastric mucosa was identified. Macroscopically, the resected specimen was 19 × 18 mm with a smooth surface and distinct margins. Microscopic examination confirmed the diagnosis of a gastric duplication cyst. The inner surface was covered with gastric gland pit-type columnar epithelial cells without atypia or neoplastic changes. The cyst wall presented layers of mucosa, muscularis mucosae, submucosa, muscularis propria, and subserosa. The patient's course after the procedure was uneventful, and he was discharged 8 days postoperatively. Gastric duplication cysts are rare and mostly asymptomatic, and their laparoscopic partial resection is safe and effective.
