Sonographic diagnosis of gastric duplication cyst communicating with the gastric lumen

Gastric duplication cysts are rare congenital anomalies, which account for about 7% of all enteric duplications. We report the sonographic findings of a rare case of gastric duplication cyst, communicating with the gastric lumen in a 30-year-old woman.

Endoscopic treatment of a large gastric duplication cyst with hook-knife and snare (with video)

A 23-year-old woman presented with recurrent epigastric pain of several years' duration. EGD revealed a large gastric subepithelial lesion (A) that on EUS was shown to be a 5.1 × 4.2-cm cyst with anechoic content that contained echogenic debris and 4 distinct walls, suggestive of a gastric duplication cyst. The decision to treat the lesion endoscopically was based on the patient's chronic recurrent pain, which was nonresponsive to a variety of medications including proton pump inhibitors, antispasmodics, and prokinetic agents, as well as the risk of complications because of the lesion's large size.

Gastric duplication cysts as a rare cause of haematemesis: diagnostic challenges in two children

Gastric duplication cysts are rare congenital alimentary tract anomalies. We describe the importance of imaging in two children with haematemesis due to gastric duplication cysts. We emphasize the necessity for a high clinical index of suspicion for early diagnosis.

Gastric duplication cyst lined by pseudostratified columnar ciliated epithelium: a case report and literature review

Gastric duplication cyst (GDC) lined by pseudostratified columnar ciliated epithelium (PCCE) is an uncommon lesion stemming from a foregut developmental malformation. Its clinical and radiological presentation is usually nonspecific. In this study, we reported a 76-year-old man who presented with an incidentally found perigastric mass. An exploratory laparotomy revealed a non-communicating cyst below the gastroesophageal junction, measuring 4 cm×4 cm in size. Microscopically, the gastric cyst was lined merely by PCCE. Although rare, GDC lined by PCCE should be included in the differential diagnosis of gastric wall masses. Surgical intervention is warranted in patients who have clinical symptoms, or who are aged more than 50 years.

Gastric Duplication Cyst Removed by Endoscopic Submucosal Dissection

Duplication cysts are uncommon congenital malformations that may occur anywhere throughout the alimentary tract. The stomach is an extremely rare site of occurrence. Here, we report a case of gastric duplication cyst initially presenting with a gastric submucosal tumor. A 28-year-old man complained of dyspepsia lasting 1 year and upper endoscopy revealed an ellipsoid submucosal tumor at the greater curvature of the antrum. We intended to use the injection-and-cut technique: however, after saline injection, the lesion was dented and impossible to grasp with a snare. Therefore, we decided to perform endoscopic submucosal dissection and removed the tumor without complication. Histopathology revealed a 0.6×0.6 cm-sized duplication cyst, and there has been no recurrence in 2 years.

A Case of Recurrent Pancreatitis Due to a Gastric Duplication Cyst Communicating with the Pancreatic Duct

症例は12歳の男児で，5歳時より腹痛を繰り返し，急性膵炎とそれによる仮性膵嚢胞と診断され加療を受けていたが原因は判然としなかった．12歳時に腹痛が再燃し，CTで胃重複症と胆石症を指摘され，手術を施行した．まず胆嚢を摘出した．胃幽門部大彎の重複胃が，横行結腸間膜に沿って舌状に張り出した分葉膵と癒着していた．両者を接合部で切離すると互いに交通していたが，胃と重複胃の交通はみられなかった．分葉膵断端からの造影により主膵管が描出された．重複胃の粘膜および分葉膵を切離した．消化管重複症が胃に生じることは比較的まれであるが，重複胃と膵が直接交通した症例は，PubMedで検索したかぎり本症例を含めてこの50年で15例（本邦では4例）と極めてまれであり，診断と治療に難渋した報告が大半を占める．本症例では重複胃内容のドレナージが不良になることで分葉膵が膵炎を繰り返したと考えられた．

Gallstone fistula with a gastric duplication cyst: an unusual complication of cholecystitis.

Cholecystitis can result in complications if not completely treated. These include gallbladder empyema, perforation and cholecystoenteric fistula.We report the first incidence of cholecystitis resulting in a gallstone fistula with a gastric duplication cyst. A 71 year old patient presented with generalised peritonism that was worst in the epigastric area. Computer tomography (CT) revealed a perforated necrotic gallbladder. Emergency laparotomy, cholecystectomy, partial gastrectomy and Roux-en-Y reconstruction was required. The patient made a slow but full recovery.Pathology results revealed that chronic cholecystitis had resulted in a fistula with a duplication cyst overlying the greater curve of the stomach. Several one centimeter gallstones were found within the cyst cavity.

A case of perforated multiple gastric duplication cysts with five-layered appearance on ultrasonography

A case of perforated multiple gastric duplication cysts is presented. One of the gastric duplication cysts without perforation was seen on ultrasonography (US) with the following specific findings of gastric duplication cysts: a five-layered appearance, fold-like structures in the wall, and blood supply from the gastroepiploic artery. Other cysts with perforation presented with irregular and thin walls with a lack of the "double-wall sign" on US. These characteristic findings may be specific to perforated multiple gastric duplication cysts.

Laparoscopic Excision of Foregut Duplication Cyst of Stomach

Retroperitoneal gastric duplication cysts lined by ciliated columnar epithelium are extremely rare lesions and its presentation during adulthood is a diagnostic challenge for treating clinicians. This entity often resembles cystic pancreatic neoplasm, retroperitoneal cystic lesions and sometimes as an adrenal cystic neoplasm. Correct diagnosis on the basis of radiological investigation is difficult and histopathologic analysis. We report a case of gastric duplication cyst in a 16year old girl that mimicked as a retroperitoneal/pancreatic/adrenal cystic lesion and was successfully managed by laparoscopy.

Recurrent Acute Pancreatitis Caused by a Gastric Duplication Cyst Communicating with an Aberrant Pancreatic Duct

A 38-year-old woman was hospitalized in August 2007. This visit was her fifth episode of acute pancreatitis. Computed tomography revealed a cystic structure located near the antrum. Communication between this structure and the pancreatic duct was revealed by endoscopic retrograde cholangiopancreatography. Ultrasonography revealed that the cyst wall had a layered structure. Thus, we regarded it as a gastric duplication cyst. We thought that the gastric duplication cyst communicating with an aberrant pancreatic duct was responsible for the recurrent acute pancreatitis. In August 2008, a cyst gastrostomy was performed between the gastric duplication cyst and the stomach. No recurrence of acute pancreatitis has since occurred.

Gastric, pancreatic, and ureteric duplication

We report a case of an 8-month-old, asymptomatic child who was incidentally detected to have two cystic structures in the abdomen. Surgical exploration revealed a gastric and pancreatic duplication cyst along with a blind-ending duplication of the right ureter. Excision of the duplications was relatively straightforward, and the child made an uneventful recovery. This constellation of duplications has not been reported before.

Prenatal detection of fetal gastric duplication cyst: A case report

Enteric duplication cysts are rare congenital malformation, of these, only 4% are gastric origin. It is diagnosed in 80 % of the patients before 2 years of age. Recently, prenatal diagnostic ratio gets higher through sonography and several diagnostic methods. In this paper, we describe a case of a cystic gastric duplication diagnosed prenatally with brief reviews of literature.

Adenocarcinoma arising from gastric duplication: a case report with literature review.

Gastric duplication is a rare congenital malformation. We report the case of a 50-year-old man with adenocarcinoma derived from gastric duplication. He was referred to our institute because of persistent vomiting due to pyloric stenosis. Abdominal computed tomography revealed two cystic lesions: a 2-cm mass located along the greater curvature of the upper gastric corpus and a 3-cm mass adjacent to the bulbus. Under the diagnosis of gastric duplication cysts, the oral cyst was removed with the gastric wall and the other cyst lesion firmly adhered to the bulbus was treated with distal gastrectomy. Based on histological findings showing adenocarcinoma in the anal duplication cyst wall and regional lymph node metastases and cancer invasion into the duodenal stump, pancreatoduodenectomy was performed 9days after the initial surgery. Invasion into the pancreas head and duodenal walls was seen in the resected specimen. Although the postoperative course was uneventful, he died of local recurrence and multiple liver metastases 14months after surgical treatment. This case report with literature review indicates that alimentary tract duplication cysts should be recognized as risky lesions of cancer development in patients aged 50years or over.

Quiste de duplicación gástrico: diagnóstico por punción-aspiración guiada por ecoendoscopia

Duplication cysts are rare gastrointestinal congenital abnormalities. They can occur anywhere throughout the gastrointestinal tract, and gastric duplication cysts are most uncommon, representing only 4-8% of all gastrointestinal duplication cysts. Nowadays several theories try to explain the pathogenic mechanisms involved. These cysts are usually diagnosed during early childhood, and very rarely are detected in adults, mostly incidentally due to a lack of symptoms. Close to 50% of gastric cysts are associated with other abnormalities. It is extremely important that a meticulous differential diagnosis is performed regarding other diseases, mainly malignancies with a cystic component. Although extremely uncommon, a malignant transformation of these lesions has been reported, which highlights the importance of a correct diagnosis. Herein we report the case of a duplication cyst in an adult, which was detected by endoscopic ultrasound-guided fine-needle aspiration, recently proposed as the most accurate technique for the identification of these lesions.

A rare presentation in a case of gastric duplication cyst communicating to the pancreatic duct: coincidental detection during pyloromyotomy for hypertrophic pyloric stenosis

A rare case of gastric duplication of childhood is reported. A 1-month-old boy underwent pyloromyotomy for infantile hypertrophic pyloric stenosis. At laparotomy, a protruding lesion was identified in the anterior wall of the pylorus. The pylorus was hypertrophic as indicated preoperatively, and a normal pyloromyotomy was performed. Wedge biopsy of the protruding lesion revealed an intestinal structure, and gastric duplication was diagnosed. The child remained asymptomatic thereafter, but considering the risk of the duplication becoming symptomatic, a second laparotomy was performed at 1 year of age. The duplication cyst shared part of the wall with the pylorus, and the cyst was removed by cystectomy, leaving the pyloric muscle intact. The cyst was found to be communicating with the pancreatic duct. The child is doing well without any symptoms as of 18 months after second laparotomy. To the best of our knowledge, this is the youngest case of gastroduodenal duplication with pancreatic duct communication yet reported.

Completely isolated alimentary tract duplication in a neonate

A rare case of a completely isolated, alimentary tract duplication cyst in a 27-day-old neonate is reported. The duplication cyst was detected on antenatal fetal ultrasound and magnetic resonance (MR) imaging at 27 weeks' gestational age. At surgery, the duplication cyst was in a retroperitoneal site with no apparent communication between the cyst and any portion of the alimentary tract. On histopathological examination, the diagnosis was a gastric duplication cyst. The patient's postoperative course was uneventful. There have been eight cases of completely isolated duplication reported in the literature, of which seven were detected during the prenatal or neonatal period. No previous report in the English literature has described the fetal MR imaging findings of this type of duplication cyst.

Pancreatic somatostatinoma and tuberous sclerosis: case report of an exceedingly rare association

smooth muscle. A common blood supply should be present. It should be lined by alimentary-tract epithelium. Rarely, respiratory-tract epithelium, in conjunction with alimentary-tract epithelium, has been noted. In adults, diagnosis is very difficult before surgery. Gastric duplication cysts are usually asymptomatic. However, signs and symptoms may include epigastric pain, abdominal mass, or vomiting. Rarely, GI bleeding, pancreatitis, peritonitis, malignancy, or even acute abdomen may result. Often, a GDC may be mistaken as a pancreatic pseudocyst, which is more common. Normal levels of pancreatic enzymes and no personal history of pancreatitis may suggest a gastric duplication cyst. Unlike GDC, the pancreatic pseudocyst is generally associated with repeated attacks of pancreatitis. They lack an epithelial lining and contain amylase-rich fluid. US, CT, and EUS may help in the diagnosis. In our case, the diagnosis was made before surgery by EUS-guided cyst aspiration and ERP. Surgical resection led to a satisfactory outcome. This case provides a fascinating opportunity to explore embryogenesis of the alimentary tract, as well as highlighting the usefulness of EUS and ERP in preoperative diagnosis.

Unusual case of massive hemorrhage of a gastric duplication cyst in a very advanced age

The objective of this study was to report an unusual case of gastric duplication in an 82-year-old female patient. The patient was treated immediately by Billroth I partial gastrectomy due to massive hematemesis. The surgical specimen was histopathologically examined. The histopathologic report confirmed the operative diagnosis of a gastric duplication cyst. Gastric duplication cysts are rare congenital abnormalities occurring mainly in the pediatric population and rarely in adults. They account for 2% to 7% of all gastrointestinal duplications, having a male to female ratio of 2:1 (Agha et al., AJR Am J Roentgenol 137:406-407, 1981; Macpherson, Radiographics 13:1063-1080, 1993). Gastric duplication cysts present with a variety of symptoms and complications including hematemesis. The massive upper gastrointestinal hemorrhage in our octogenarian patient indicates that there is no age limit in clinical manifestations of this rather common in the pediatric population, congenital malformation of the stomach.

Prenatal diagnosis of an intrathoracic gastric duplication: a case report

We report an intrathoracic gastric duplication cyst detected antenatally on obstetrical ultrasonography at 33 weeks of gestation. After birth, the newborn was directly intubated. At day 19, the intrathoracic cyst was removed, and the patient discharged on his 27th day of life. Histologic findings confirmed the diagnosis of a gastric duplication cyst. This appears to be the first reported case of an intrathoracic gastric duplication detected antenatally. Intrathoracic gastric duplication should be among the differential diagnosis of any mediastinal cyst discovered antenatally; its detection allows appropriate management at birth.
