Acute Ectopic Pancreatitis Occurring after Endoscopic Biopsy in a Gastric Ectopic Pancreas
Clinical endoscopy, 2014Co-Authors: Seong Jun Lee, Gwang Ha Kim, Youn Park, Sang A Choi, Sang Hee Lee, Yu Yi Choi, Moo Song Jeon, Geun Am SongAbstract:Ectopic Pancreas is a congenital anomaly and the most common type of Ectopic tissue in the gastrointestinal tract. Most patients with an Ectopic Pancreas are asymptomatic and rarely have complications. Ectopic pancreatitis after an endoscopic biopsy has not been reported. We report a patient who developed acute Ectopic pancreatitis in the stomach after an endoscopic biopsy. A 71-year-old male patient presented with a subepithelial tumor (SET) in the stomach and had no symptoms. Endoscopic ultrasonography demonstrated a 30-mm hypoechoic mural mass, lobulated margins, and anechoic duct-like lesions. To obtain proper tissue specimen, endoscopic biopsy was performed through the opening on the surface of the mass. The pathologic results confirmed an Ectopic Pancreas. One day after the endoscopic biopsy, he developed persistent epigastric pain. His serum amylase and lipase elevated. Computed tomography of the abdomen showed swelling of the SET and diffuse edema of the gastric wall. His condition was diagnosed as acute Ectopic pancreatitis occurring after endoscopic biopsy.

Endosonographic findings of gastric Ectopic Pancreas: a single center experience.
Journal of gastroenterology and hepatology, 2011Co-Authors: Sung Han Park, Gwang Ha Kim, Youn Park, Na Ri Shin, Jae Hoon Cheong, Ji Yoon Moon, Bong Eun Lee, Geun Am Song, Hyung-il Seo, Tae Yong JeonAbstract:Background and Aim: Ectopic Pancreas is a common submucosal lesion in the stomach, but its histological diagnosis is usually difficult when tissue samples are obtained with a conventional biopsy forceps. The aim of this study was to describe the endosonographic features of gastric Ectopic Pancreas. Methods: We retrospectively analyzed a database of all patients who underwent endoscopic ultrasonography (EUS) at Pusan National University Hospital from July 2006 to August 2010. A total of 26 patients with histologically confirmed Ectopic Pancreas were included in the study. The EUS features of their lesions were analyzed. Results: Ten lesions were located in the antrum, and 16 lesions were located in the body. Nine lesions (34.6%) showed an umbilication or central dimpling on the surface, and a mural growth pattern was most commonly observed (61.5%). Twenty-four lesions (92.3%) showed hypoechoic echogenicity, and 13 lesions (50.0%) were heterogeneous. The borders were indistinct in 16 lesions (61.5%) and lobulated margins were observed in 16 lesions (61.5%). Anechoic cystic or tubular structures appeared in 17 lesions (65.4%), and 20 lesions (76.9%) involved two or more sonographic layers. Conclusions: The characteristic EUS features of Ectopic Pancreas are indistinct borders, lobulated margins, presence of anechoic duct-like structures, a mural growth pattern, and localization within two or more layers. These EUS features are potentially useful for differentiating Ectopic Pancreas from other mesenchymal tumors in the stomach.

Endoscopic removal of gastric Ectopic Pancreas: an initial experience with endoscopic submucosal dissection.
World journal of gastroenterology, 2010Co-Authors: Dong Yup Ryu, Gwang Ha Kim, Youn Park, Jae Hoon Cheong, Bong Eun Lee, Dong Uk Kim, Hyun Young Woo, Jeong Heo, Geun Am SongAbstract:AIM: To evaluate the therapeutic usefulness and safety of endoscopic resection in patients with gastric Ectopic Pancreas. METHODS: A total of eight patients with Ectopic Pancreas were included. All of them underwent endoscopic ultrasonography before endoscopic resection. Endoscopic resection was performed by two methods: endoscopic mucosal resection (EMR) by the injection-and-cut technique or endoscopic mucosal dissection (ESD). RESULTS: We planned to perform EMR in all eight cases but EMR was successful in only four cases. In the other four cases, saline spread into surrounding normal tissues and the lesions became flattened, which made it impossible to remove them by EMR. In those four cases, we performed ESD and removed the lesions without any complications. CONCLUSION: If conventional EMR is difficult to remove gastric Ectopic Pancreas, ESD is a feasible alternative method for successful removal.

Ectopic Pancreas and foveolar hyperplasia in a newborn: a unifying etiopathogenesis for gastric outlet obstruction.
Journal of pediatric gastroenterology and nutrition, 2004Co-Authors: Ana Catarina Fragoso, Jorge Correia-pinto, José Luis Carvalho, Jorge Amil Dias, Maria Pilar Troncoso, José Estevão-costaAbstract:Gastric outlet obstruction in infants usually is attributable to infantile hypertrophic pyloric stenosis (IHPS). Rare causes, such as foveolar hyperplasia (FH) (1–3) or Ectopic Pancreas (4,5), have been reported. In this case we describe a newborn infant with gastric outlet obstruction related to coexisting Ectopic Pancreas and FH who was being treated with prostaglandin (PG) E1. A unifying etiopathogenesis for gastric outlet obstruction is proposed.

Ectopic Pancreas presenting as ampulla of Vater tumor.
American journal of surgery, 2008Co-Authors: Sheng-der Hsu, De-chuan Chan, Huan-fa Hsieh, Teng-wei Chen, Shao-jiun ChouAbstract:Ectopic Pancreas is relatively rare and is defined as pancreatic tissue that is situated abnormally, has no contact with the normal Pancreas, and has its own ductal system and blood supply. It is usually an incidental finding in clinical practice. Most patients with an Ectopic Pancreas are asymptomatic, and, if present, symptoms are nonspecific and depend on the site of the lesion and the different complications encountered. Heterotopic pancreatic tissue has been found in several abdominal and intrathoracic locations, most frequently in the stomach (25%-60%) or the duodenum (25%-35%). Herein, we report a patient presenting with symptoms of ampullary tumor with obstructive jaundice, but the imaging study did not suggest the possibility of Ectopic Pancreas preoperatively.

Ectopic Pancreas in the Ampulla of Vater with Obstructive Jaundice
Digestive surgery, 2006Co-Authors: Shao-jiun Chou, Yu-wei Chou, Hsiang-chun Jan, Victor Tze-kai Chen, Tzu-hung ChenAbstract:Ectopic Pancreas is an uncommon condition and is usually found in the gastrointestinal tract, such as stomach, duodenum and jejunum. However, Ectopic Pancreas in the ampulla of Vater is rare and its clinical presentations may be similar to periampullary cancer. It is difficult to diagnose preoperatively. We present such a case where the diagnosis was proven postoperatively. Our patient, a 51-year-old man, presented with epigastric pain, jaundice, weight loss and abnormal laboratory data. Imaging study, including abdominal sonography, abdominal computerized tomography with contrast and endoscopic retrograde cholangiopancreatography, showed a mass protruding into the ampulla of Vater. The mass was resected and histological examination revealed an Ectopic Pancreas. The patient presented with symptoms of periampullary tumor but the imaging study did not reveal an obvious lesion for us consider the possibility of Ectopic Pancreas. Surgical excision is indicated for symptomatic cases.
