A Case of Apical Hypertrohic Cardiomyopathy Associated with Pheochromocytoma / 대한내분비학회지

Pheochromocytomas often present with cardiovascular manifestations, such as arrhythmia, angina pectoris and acute myocardial infarction and so on. Both dilated and nonobstructive hypertrophic cardiomyopathies are also rare complications of pheochromocytomas. In hypertrophic cardiomyopathy, an apical variant form constitutes about 25% of cases in Japan, but only 1 to 2% of those in non-Japanese populations, including Korea. The cause of apical hypertrophic cardiomyopathy (AHC) remains unknown. Recently, some cases of AHC associated with pheochromocytomas have been reported, with catecholamine thought to be an important cause. AHC associated with a pheochromocytoma has never been previously reported in Korea. Herein is reported our experience of a case of apical hypertrophic cardiomyopathy associated a pheochromocytoma with a review of the literature

A Case of Malignant Coloenteric Fistula / 대한소화기내시경학회지

Malignant coloenteric fistula is a rare complication of colon cancer. Colon carcinoma is the most common etiology of this entity. Clinical features are diarrhea, weight loss, anemia and feculent vomiting. The diagnosis is most often made by barium enema examination. The primal therapy is operation. We present a case of a 51-year old male in whom a coloenteric fistula caused by transverse colonic carcinoma. He complained of abdominal pain, diarrhea and dizziness. UGI series demonstrated a fistulous track between colon and small bowel. On abdominal CT examination, a mass involving hepatic flexure of colon with a fistulous tract and metastatic nodules in right lobe of liver were found. Colonoscopy revealed a circumferential mass and the orifice of the fistula. The patient refused operation and expired one month after discharge.

A Case of Meckel's Enterolith / 대한소화기내시경학회지

The term enterolith refers to concretions formed within the gastrointestinal tract. Enteroliths are thought to result from stasis and are usually found proximal to an area of stricture or within diverticulum. Meckel's diverticulum occurs in 1% to 3% of the population at autopsy and is the most common congenital anomaly of the gastrointestinal tract. Common complications of Meckel's diverticulum include hemorrhage, infection, inflammation, and intussusception. However, enterolith formation in a Meckel's diverticulum, which referred to as Meckel's enterolith, is rare. A 58-year-old female who experienced constipation and low abdominal pain for 20 years, was admitted due to severe low abdominal pain for 3 days. A 3 2 cm sized, lozenge-shaped radiopaque stone with peripheral dense calcification and radiolucent center, located between two areas of stricture in the distal ileum, was observed in abdominal radiograph, abdominal sonogram, small bowel study, and CT scan. Pathologic findings after surgery reveal an enterolith in Meckel's diverticulum without ectopic gastric mucosa. The case of Meckel's enterolith is herein reported.

A Case of Hydrogen Peroxide Induced Colitis / 대한소화기내시경학회지

Hydrogen peroxide has been used for various medical purposes and also recommended in the disinfection process for endoscopes. However, hydrogen peroxide as a cause of chemical colitis or disinfectant colitis has been infrequently reported. The endoscopic findings of hydrogen peroxide induced colitis revealed pseudomembranous-like enteritis such as white plaques, erythema, foamy liquid, patchy, granularity, and ulcerations, resulting from effervescence caused by the release of oxygen from the breakdown of hydrogen peroxide. A 36 year-old single male, who had 30 ml of 3% hydrogen peroxide inserted into his anus the day before due to sexual reasons, was hospitalized as a result of suffering from hematochezia, tenesmus, and lower abdominal pain. Colonoscopy revealed discrete or confluent white plaques adherent to the colonic mucosa, severe erythema on the surrounding mucosa, patchy granularity, and scattered ulcerations up to 28 cm from the anal verge. Pathologic finding revealed inflammatory cells infiltration, variable sized vacuoles, vascular congestion, hemorrhage, fibrin deposition and ulcerations with regenerating epithelium in the lamina propria, consistent with acute mucosal injury caused by hydrogen peroxide. A case of hydrogen peroxide induced colitis is herein reported.

Endoscopic Ligation Therapy for Gastric Angiodysplasia / 대한소화기내시경학회지

Gastric angiodysplasia may be responsible for up to 2% to 6% of upper gastrointestinal bleeding. Moreover, gastric angiodysplasia may be particularly difficult to treat and is usually associated with a high rebleeding rate. Bleeding due to gastric angiodypsplasia is usually treated by various endoscopic approaches, including argon and Nd:YAG laser photocoagulation, monopolar or biopolar electrocoagulation, heater probe, or injection. Associated complications of these methods, however, such as perforation, acute bleeding during the procedure, or delayed massive hemorrhage have been reported. Recently a few reports have been suggested that endoscopic ligation therapy is a safe, effective treatment for gastric angiodysplasia. A 70-year-old man, who had undergone subtotal gastrectomy for perforation of a duodenal ulcer for 20 years, was admitted due to melena and dizziness persisting for 1 week. A gastroscopy revealed a single angiodysplasia with active bleeding just above the anastomotic site of the remnant stomach. Endoscopic ligation therapy was performed successfully and the bleeding stopped immediately after endoscopic ligation. Since then, no recurrence of bleeding has been reported to date.
