Angiodysplasia is uncommon and frequently undiagnosed and presents a taxing surgical problem. It is usually diagnosed for unexplained gastrointestinal bleeding. Angiography gives a little information about wax and wane pattern of bleeding in the lesion. We experienced I case of angiodysplasia in G-I tract(especially colon) diagnosed in the Seoul National University Hospital. This report summarized our experience and review of east and west literature.

Angiodysplasia is an important vascular lesion of the gastointestinal tract, located at the site of ectasia of intestinal submucosal veins and overlying mucosal capillaries. It is a major cause of morbidity from gastrointestinal bleeding in old age, but rather rare in children. Its cause is still unknown, though is mostly considered to be acquired as a result of a degenerative process associated with aging. We experienced a case of colonic angiodysplasia in 14-year old boy, diagnosed by colonoscopy. The patient had a history of repeated hematochezia for a year. This report summarized our case and reviewed the literature.

We present a case of a 13-year-old boy with Gorham's disease involving the thoracic and lumbar spine, femur, and gastrointestinal (GI) tract, which was complicated by recurrent chylothorax and GI bleeding. The presenting symptoms were intermittent abdominal pain, back pain, and melena. Esophagogastroduodenoscopy and colonoscopy showed no abnormal lesions, but duodenal biopsy showed marked dilation of the lymphatics in the mucosa and submucosa, which revealed positive staining with a D2-40 immunohistochemical marker. In cases of GI bleeding with osteolysis, the expression of a D2-40 marker in the lymphatic endothelium of the GI tract may help to diagnose GI involvement in Gorham's disease. To the best of our knowledge, this is the first case report to pathologically demonstrate intestinal lymphatic malformation as a cause of GI bleeding in Gorham's disease.

Gastric lipoma is a typical benign submucosal tumor that is usually asymptomatic and is generally detected incidentally when performing gastroscopy. However, depending on its size and location, an atypical gastrointestinal lipoma can cause abdominal pain, diarrhea, constipation, intestinal obstruction, intussuception and life-threatening gastrointestinal bleeding. We report herein a case of gastric lipoma with bleeding in a 43-year-old man. The gastroscopy showed a $4{\times}4$ cm ulcero-fungating submucosal mass at the anterior wall of the gastric antrum. Laparoscopic gastric wedge resection was performed and the lesion was diagnosed as gastric lipoma.

Angiodysplasia is the most common vascular abnormality of the gastrointestinal tract and probably the most frequent cause of recurrent lower intestinal bleeding in otherwise healthy elderly patients. Also, it is an important cause of hemorrhage in chronic renal failure observed in up to 19~32% of patients. Bleeding due to gastric angiodysplasia is treated by various endoscopic approaches, including argon and Nd : YAG laser photocoagulation, monopolar or bipolar electrocoagulation, heater probe, injection sclerotherapy, band ligation or hemoclipping. A 15-year-old boy, who had undergone hemodialysis for chronic renal failure for about 10 years, was admitted due to melena and progressive anemia. A gastroduodenoscopy revealed a cherry red and fern-like lesion with oozing on the posterior wall at junction of gastric body and fundus. Endoscopic hemoclipping therapy was performed. However, melena recurred four days later. Argon plasma coagulation and hemoclipping therapy were performed again. Since then, no recurrence of bleeding has been observed.

Nonsteroidal antiinflammatory drugs(NSAIDs) are widely used to treat pain. fever and inflammatory condition. But chronic-disease patients suffer from gastro-intestinal disturbances such as discomfort. nausea. peptic ulcer and severe bleeding because NSAIDs inhibit not only COX-2 associated with anti-inflammatory activity but also COX-1 associated with adverse gastro-intestinal effects. On the basis of this fact. specific COX-2 inhibitors such as celecoxib and rofecoxib are introduced in the drug market. (omitted)

Of 72 patients with vitelline duct and vessel remnants, 45 (62.5 %) had symptomatic lesions. The mean age of the patients was 27.9 months. Males predominated (4.6 : 1). There were 22 cases of Meckel's diverticulum, 6 of Meckel's diverticulum attatched to the umbilicus with a fibrous band, 6 cases of patent vitelline duct, 5 cases of vitelline artery remnants as a fibrous band and 2 cases each of umbilical sinus and polyp, and vitelline cyst. Twenty-three patients (51 %) presented with intestinal obstruction, 6(13 %) with rectal bleeding, 4(9 %) with perforated Meckel's diverticulum, 5 with intestinal juice drainage through umbilicus, 5 with umbilical lesions, 1 with abdominal mass, and 1 with sepsis. Intestinal obstruction due to fibrous band developed during infancy(average age; 4.6 months). Seventeen asymptomatic Meckel's diverticulum, 8 obliterated vitelline artery remnants and 1 vitelline vein remnant as fibrous band, and 1 vitelline cyst were found incidentally at laparotomy. About 82 % of the complicated Meckel's diverticulum presented in infants and children less than 4 years of age.

The small bowel is the most difficult intestinal segment to examine. Radiologic tests are mostly insensitive and double-balloon enteroscopy is unsuitable for the younger child. Capsule endoscopy is a novel wireless method of investigation of the small bowel. The primary indications for capsule endoscopy include evaluation of obscure gastrointestinal bleeding, small bowel Crohn's disease, and polyposis syndromes. Capsule endoscopy offers an accurate and effective means of investigating the small bowel in children. Capsule retention is a potential complication of capsule endoscopy. This review provides the indications, safety, and limitations of wireless capsule endoscopy in children.

To observe the clinical course and intestinal histopathology in heavy infection of Fibricola seoulensis, an experimental study was performed in mice. Clinical, experimental infection with 1, 000 metacercariae. On the 11th day after infection, the mice began to die and all of the infected mice were dead by the 16th day. The infected mice showed gradual weight loss. Occult blood was detected after the 10th day. Diarrhea accurred after the 9th day and was recognized in all of the infected mice on the 12th day. Hemoglobin and mean corpuscular hemoglobin decreased significantily after the 12th day, and mean corpuscular hemoglobin concentration decreased in all infected mice. The histopathological changes were more marked in the duodenum than in the jejunum or ileum. Major changes were villous atrophy and crypt hyperplasia, with decreased villus/crypt ratio, inflammatory cell infiltration and stromal edema. The present results suggest that the cause of death of mice heavily infected with F. seoulensis should be malnutrition and severe fluid loss due to malabsorption, together with intestinal bleeding.

A vitelline duct (VD) anomaly is a relatively common congenital abnormality of the umbilical area. The anomalies include patent vitelline duct (PVD), cyst, fistula or sinus. The incidence is approximately 2% of the populations, but development of symptoms is rare. Recently, we experienced two cases; PVD accompanied by a small omphalocele and intestinal volvulus due to mesenteric band between Meckel's diverticulum and the mesentery. Thereafter,we evaluated the data of vitelline duct anomalies for 27 years. From 1980 to 2006, 18 cases of VD anomalies were reviewed based on the hospital records retrospectively. There were 15 boys and 3 girls and age ranged from 2 days to 15 years. Among the 18 cases, 15 cases were symptomatic and consisted of Meckel's diverticulum (10 cases), PVD (4 cases) and umbilical polyp (1 case). Three asymptomatic cases of Meckel's diverticulum were found incidentally were and were observed without resection. Ten cases of Meckel's diverticulum were presented with intestinal bleedings (4 cases), intestinal obstructions (5 cases) and perforation (1 case). Wedge resections and segmental resections of ileum were performed in 8 patients and 2 patients, respectively. Postoperative complications were adhesive ileus (1 case) and wound seroma (1 case). Small omphaloceles were accompanied in two of 4 PVD patients. There was 1 small omphalocele case which was accompanied by a prolapse of ileum. In summary, VD anomalies were more common in male and more than half of them were found in patients less than 1 year of age. PVD was diagnosed most frequently in neonates. Meckel's diverticulum presented with intestinal obstruction more frequently than bleeding.
