Gastric duplication is a rare anomaly which account for only 3.8% of all gastrointestinal duplication. Gastric duplications are usually cystic lesion without communication with lumen. Most frequent presentation is an abdominal mass with vomiting, mainly diagnosed within the first year of life. Surgical removal is necessary in all cases, and optimal timing for surgery is the time that diagnosis is made. However, prenatally diagnosed gastric duplication is getting more common, and determining timing for surgery is not easy due to absent or minimal symptoms just after birth. We experienced prenatally diagnosed gastric duplication in a female newborn baby that gastric duplication was suggested in $24^{th}$ week of gestational age through prenatal ultrasonogram. Surgical removal was done at 3 months after birth, and showed good results. We think that natural history of gastric duplication and prevalent age of surgical disease which is similar to gastric duplication such infantile hypertrophic pyloric stenosis should be considered when timing of surgery on prenatally gastric duplication is decided.

Pulmonary sequestration is a rare congenital malformation of the lung and occasionally accompanied with upper gastrointestinal anomalies. Based on the embryologic development, they are grouped as broncho-pulmonary foregut malformation. We present one the case of the intralobar pulmonary sequestration with gastric duplication. The sequestrated pulmonary tissue was 9x7x8cm in dimension, multiseptated and multiloculated, and supplied by a systemic artery of 7mm diameter from the abdominal aorta. The gastric duplication was 8cm in diameter located at the posterior wall of the stomach without communication with the gastric lumen.

Gastric duplication cyst is a rare congenital anomaly of the gastrointestinal tract and is especially uncommon in adults. Most cases in adults are discovered incidentally on radiological examination or gastric endoscopy. Accurate diagnosis of these cysts before resection is difficult. Differential diagnoses are varied. Malignant transformation of a gastric duplication cyst is very rare. We present three cases of asymptomatic noncommunicating gastric duplication cysts in adults.

Gastric duplication cysts (GDCs) are rare congenital anomalies. Presentation of GDCs varies from an asymptomatic abdominal mass to fulminant or massive gastrointestinal (GI) bleeding. Herein, we describe a case of a GDC in a 10-month-old infant presenting with unexplained massive GI hemorrhage and hematemesis. An abdominal ultrasound was negative, while computerized tomography was, initially, inaccessible. Through a series of repeated esophagogastroduodenoscopies, we documented penetration of the GDC into the gastric cavity that was later confirmed by computerized tomography. The patient was treated successfully with surgical resection.

Purpose: Abdominal cysts of gastrointestinal origin are rare. Their rarity and varied clinical presentations make their pre-operative diagnosis difficult. Methods: Fourteen patients with histological diagnosis of cysts of gastrointestinal origin admitted between 2009 and 2015 were retrospectively analyzed with respect to age, sex, clinical presentation, diagnostic modality, site and type of cyst, management, outcome and follow-up. Results: The mean age at presentation was 4 years and there were six males and eight females. Abdominal pain was the most common presenting symptom. Five patients had an acute presentation-three had distal ileal mesenteric cysts and two had ileal duplication cyst sharing a common wall with ileum. Six patients presented with chronic abdominal pain and lump-three patients had omental cysts and three had mesenteric cysts-two of these in distal ileum and one in sigmoid colon. Two patients presented with antenatally diagnosed palpable abdominal lump. One had a mesenteric cyst of the ileum and the other had a distal ileal duplication cyst which required excision with resection and anastomosis. One patient had an atypical presentation. He was a known case of sickle cell trait and had presented with vague abdominal pain, recurrent cough and multiple episodes of haemoptysis over a period of one year. At laparotomy, gastric duplication cyst was found which was excised completely. Histopathology confirmed the diagnosis. Conclusion: Cysts of gastrointestinal origin are rare and have varied presentation. Surgical excision is the mainstay of treatment. The results and prognosis are good.

A congenital duplication cyst, which presents with symptoms of gastric outlet obstruction, is an unusual disorder in humans and a rare condition in animals. A 5-day-old male Korean native cattle was presented with anorexia and no defecation. On exploratory laparotomy, an oval shaped mass ($16{\times}7$ cm) was identified on the antimesenteric border of the proximal duodenum, with no communication between the intestinal lumen and the mass itself. Surgical correction for gastrointestinal tract patency was performed. The calf recovered well and was clinically normal three months after surgery. This case is the first report of a duodenal duplication cyst in a Korean native cattle.

Gastrointestinal duplications are rare congenital malformation that may require surgical intervention in the neonate, infant, and occasionally the older child. Symptoms produced by duplications vary according to their location, size, type and histology. We report the clinical characteristics and the surgical results of 9 cases of the gastrointestinal duplications treated at at Asan Medical Center between 1989 and 2000. Five patients were boys and four were girls; age of patients ranged from 5 days to 10 years. Eight duplications were cystic and one was tubular. One involved the stomach; five were in the ileum, and two in the cecum. The most common presentation was intestinal obstruction. There was associated anomaly in one patient, pulmonary sequestration and double ureter. Ectopic gastric mucosa was found in two. All patients underwent surgical resection. There was no perioperative mortality or morbidity. Although gastrointestinal duplication is a rare entity. consideration of associated anomalies and being familiar with the anatomy and clinical features are required for adequate management. In cystic form. complete excision is recommended but planned surgery is required for long segment tubular lesion.

Intestinal duplication cysts are characterized by the attachment to some part of the gastrointestinal tract with which a blood supply is shared, and have an epithelial lining resembling some part of the alimentary tract. A 15-month-old female was admitted to our hospital with cyclic irritability, vomiting, and blood-tinged stool. The results of an ultrasound showed an ileocolic intussusception and a 1.3 cm cystic mass had double-wall sign and a Y-configuration with an adjacent ileal loop. She had a past history of two ileocolic intussusceptions. The cystic mass was considered to be a pathologic lead point, so resection and end-to-end anastomosis was performed. The gross and histologic evaluation of the specimen demonstrated a $2.4{\times}2.4$ cm cystic mass containing yellow mucoid fluid and the cyst wall was lined with intestinal and gastric mucosa and enclosed by a layer of muscle, which was shared with the adjacent ileum.
