Complicated Gastric Duplication Cyst in Adult: a Case Report

Aims Gastric duplication cyst is a very rare gastrointestinal congenital congenital anomaly and most of the cases are diagnosed in the neonatal period. It is rarely observed in adults. Gastric duplication cysts are usually asymptomatic and usually discovered incidentally during endoscopy or laparotomy or very rarely after getting complicated. Accurate diagnosis of these cysts before resection is difficult. Differential diagnoses are varied, including gastrointestinal stromal tumors (GISTs), neuroendocrine tumors, pancreatic pseudocysts, and neurogenic tumors.Malignant transformation of a gastric duplication cyst is very rare.We present a case of complicated noncommunicating gastric duplication cysts in adults who presented with clinical of gastric outlet obstruction and successful endoscopic treatment.

Methods We present a case of complicated noncommunicating gastric duplication cysts in adults who presented with clinical of gastric outlet obstruction and successful endoscopic treatment.

Results A 55-year-old man presented with recurrent epigastric pain and fullness for four months. No significant findings were noted during physical examination and routine blood tests. A contrast-enhanced abdominal computed tomography scan demonstrated a cystic lesion without any significant enhancement a the first part of duodenum. The lesion was initially thought to be a duodenal duplication cyst. The patient underwent a gastroscope and it was noted a circumferential antrum bulging with smooth mucosa. An endoscopic ultrasound was showed anechoic, homogenous lesions with regular margins arising from the submucosal layer at antrum. Endoscopic gastrocystostomy was performed. The patient was discharged in good condition after 2 days.

Conclusions In conclusion, a gastric duplication cyst is a rare congenital anomaly that is difficult to diagnose definitively. It should be considered as a differential diagnosis of gastric cystic lesions. Simple surgical excision is considered the optimal therapy. When a complete excision of these cysts is not possible cystogastrostomy, or partial gastrectomy is done.
