Intussusception Secondary to Jejunal Lymphangioma in a 13-year-old Girl / 대한소화기학회지

Lymphangioma is a benign tumor composed of numerous small or large thin-walled lymphatic spaces. It shows a predilection for head, neck, and axilla. Jejunal lymphangioma in children is extremely rare. We present a case of 13-year-old girl with jejuno-jejunal intussusception secondary to lymphangioma in jejunum. To our knowledge, this is the second report of jejunal lymphangioma causing intussusception in a child.

Three Cases of Colonic Anisakiasis / 대한소화기내시경학회지

Anisakiasis occurs when humans ingest raw or inadequately cooked saltwater fish or squid that is infested with anisakis larvae. The larvae invade the gastrointestinal mucosa and cause abdominal pain, nausea, vomiting and various gastrointestinal lesions. Anisakiasis of the stomach has been reported occasionally but involvement of the small bowel or colon is extremely rare. We report three cases of anisakiasis in the colon with a brief review of the relevant literature.

Endoscopic Findings in Boerhaave's Syndrome: Report of three cases / 대한소화기내시경학회지

Boerhaave's syndrome, which was first described by Herman Boerhave in 1724, is a spontaneous esophagcal rupture resulting from severe nausea and vomiting. It is a very rare disorder, frequently developed in the 4th to 6th decade of life, and affects males more commonly than females. A typical clinical triad of chest pain, fever, and subcutaneous emphysema was manifested in only 20-30% of cases involving an esophageal rupture and most patients complained of many nonspecific symptoms such as dyspnea and hematemesis. In cases of vomiting resulting from alcohol ingestion, gastrofiberscopy can be performed in hematemetic patients under the assumption of upper gastrointestinal bleeding in most cases of Boerhaave's syndrome. We report 3 patients of Boerhaave's syndrome who visited our hospital because of hematemesis. Their endoscopic findings were, 1) a large, deep oval-shaped laceration with a sharp margin on the distal esophagus 2) a cavitary lesion with internal multiple hematomas and/or necrotic debris, and 3) a formation of air bubbles in the hematoma relating to respiration.

Unusual Endoscopic Retrograde Cholangiographic Finding in a Case of Xanthogranulomatous Cholecystitis / 대한소화기내시경학회지

Xanthogranulomatous cholecystitis is a rare form of chronic gallbladder inflammation that is characterized by a severe proliferative fibrosis and has rarely been described in the radiologic literature. Like xanthogranulomatous pyelonephritis, it is an entirely benign but unusual expression of a reactive process and may be confused with a malignant neoplasm. Histologically, foamy histiocytes, multinucleated giant cells, other inflammatory cells, fibrous reaction with spindle cells, cholesterol cleft and noncaseating granuloma were found. Treatment of this benign inflammatory condition requires cholecystectomy to remove the focus of inflammation, control subsequent infection and relieve symptoms A case of xanthogranulomatous cholecystitis mimiking carcinoma of the gallbladder on abdominal USG, abdominal CT, and ERCP examination is presented with brief review of the literature.

A Case of Idiopathic Segmental Ileal Dilatation with Acute Intestinal Bleeding / 대한내과학회지

Idiopathic segmental ileal dilatation is a rare congenital condition in which the caliber of the bowel lumen increases locally without distal luminal obstruction or thickening of the muscle coats in involved lumen. Congenital abnormalities such as exomphalos, malrotation of the midgut, and Meckel's diverticulum are found frequently in the patients with segmental dilatation of the small bowel. Intermittent abdominal pain or anemia may be the symptoms of segmental dilatation of the small bowel in infants, children and occasionally adults. The radiologic finding in barium studies of the small bowel is characteristic axial segmental dilatation. The pathologic finding is nonspecific ulcer and mild congestion, but it has normal nervous system and smooth muscle bundle. There are no evidence of ischemic changes, inflammatory changes or neoplastic changes. The condition can be cured with surgical excision of the dilated segment. A case of idiopathic segmental ileal dilatation associated with melena and recurrent abdominal pain diagnosed by enteroclysis in a 47 years old man was presented with brief review of the literature.

Clinical Trial of Endoscopic Botulinum Toxin Injection for the Treatment of Primary Achalasia / 대한소화기내시경학회지

Primary achalasia is a disorder of swallowing in which the lower esophageal sphincter fails to relax. Traditional treatment methods are balloon dilatation and myotomy, but these methods have critical complications and even fatal including esophageal perforation, gastroesophageal reflux, and continuing dysphagia. Botulinum toxin, which has been used for dystonias of skeletal muscles, is presented as a new alternative treatment method for achalasia, aimed to lowering of LES pressure by Pasricha et al. They also reported that endoscopic botulinum toxin injection into LES was effective, safe, and simple method without any significant complication. We report 7 cases of primary achalasia treated with endoscopic botulinum toxin injection, who showed clinical improvement without any complication. We compared results of pre-treatment with those of post-treatment using botulinum toxin in the aspects of clinical, radiological, manometrical recording in these cases. Symptomatic improvement was shown in 4 cases(57.1%), symptom score was decreased from 7.43+/-0.53 to 4.43+/-2.51(p=0.03), The luminal diameter at esophagogastric junction increased from a mean of 3.21+/-0,99 mm to 5.14+/-0.90 mm (p=0.015), and luminal diameter at esophageal body decreased from a mean of 40.29+/-19.37 mm to 32.71+/-15.45 mm (p=0.015). In follow up manometric recording, peristaltic waves at the body were recovered in 2 cases(28.6%), gastroesophageal pressure gradient(AP) was non-significantly decreased from 6.30+/-4.0 mmHg to 3.12+/-4.47 mmHg (p=0.45). One patient complained of transient chest pain within one hour after the botulinum toxin injection, but she did not need any medication. We concluded that botulinum injection was a simple, safe, and effective therapeutic method for primary achalasia, even though further evaluatian should be performed in the much more cases and the results of long term follow-up, and cost-effectiveness of this method.

A Case of Small Cell Carcinoma of Gallbladder / 대한내과학회지

Carcinoma of the gallbladder is relatively rare malignancy usually found in an elderly, predominantly female population. Histologically, adenocarcinoma predominate, with only 10% to 15% being of other varieties(small cell carcinoma and others). Small cell carcinoma of the gallbladder is a rare lesion and predominantly a disease of older women with clinical history of stones. These tumors show an aggressive clinical course and death usually occurs with in a few months of the diagnosis. The diagnosis of small cell carcinoma should be based on cell morphology, histologic pattern and immunohistochemical study. Correct diagnosis is important not only because these tumors give rise to endocrine syndromes, but also because the chemotherapeutic approach to small cell carcinoma differs from that for adenocarcinoma.

A Case of Acute Pancreatitis due to Impaction of Ascaris lumbricoides into the Pancreatic Duct / 대한소화기내시경학회지

Acute pancreatitis due to impaction of Ascaris lumbricoides into the pancreatic duct is very rare. Authors hnve experienced one case of pancreatic ascariasis. Patient was a 62-year-old female with epigastric pain. Abdominal USG and endoscopic retrograde cholangiopancreatography showed characteristic finding of pancreatic ascariasis. Ascaris was removed with palypectomy snare and acute pancreatitis was resolved completely.

Clinicopathoalogic Features of Colonic Flat Adenoma / 대한내과학회지

OBJECTIVES: To determine accurate diagnosis and proper treatment, we reviewed colonoscopic and histologic findings of flat adenoma of colon, METHODS: We studied retrospectively 2148 cases of colonoscopic findings performed in our hospital from March of 1993 to September of 1995. RESULTS: 1) The incidence of adenoma is 9.5%(203 cases), and that of flat adenoma is 1.6%(34 cases). 2) The location of flat adenoma is 3 cases in rectum(8.8%), 15 cases in sigmoid colon(44.1%), 9 cases in descending colon(26.5%), 3 cases in transverse colon(8.8%) and 4 cases in ascending colon and cecum(11.8%). 3) The diameter of flat adenoma was smaller than 5mm in 17 cases(50.0%), between 5-10mm in 8 cases(23.5%) and larger than 10mm in 9 cases (26.5%). Mean size was 9.2mm. 4) In colonoscopic features, type IIa was 25 cases (73.5%), type IIa + IIc was 5 cases(14.7%) and lateral spreading tumor was 4 cases(11.8%). 5) In histologic findings, tubular adenoma was 26 cases(76.5%), tubulovillous adenoma was 6 cases (17.6%) and serrated adenoma was 2 cases(5.9%). 6) The incidence of severe dysplasia or carcinoma was zero in smaller than 5mm, 25.0%(2 case) in 5-10mm and 55.6%(5 cases) in larger than 10mm. 7) The incidence of severe dysplasia or carcinoma was 11.5%(3 cases) in tubular adenoma and 66.7%(6 cases) in tubulovillous adenoma. 8) It was confirmed by abdominal CT scan or operation that lesions were limited to intraepithelium in 4 cases, mucosa in 2 cases submucosa in 1 case and no lymph node metastasis in any case. CONCLUSION: Even though flat adenoma of colon was smaller than polypoid adenoma, the incidence of malignant change was higher. When it was smaller than 10mm, the incidence of submucosal invasion or lymph node invasion was rare. Therefore endoscopic mucosal resection(EMR) can be the treatment of choice in flat adenoma smaller than 10mm, and after EMR, it is desirable to decide the treatment modality depending on the histologic findings.
