A Case of Biliary Ascariasis with Duodenal Stenosis / 대한소화기내시경학회지

Infestation with Ascaris lumbricoides is one of the most common helminthic diseases in humans. The highly motile mature worm can cause intestinal obstructions, pancreaticobiliary diseases, appendicitis, and peritonitis. However, biliary ascariasis associated with duodenal stenosis is extremely rare. We report a case of biliary ascariasis with duodenal stenosis in a 70-year-old man. The patient was admitted to our hospital with a 2 month history of epigastric pain and vomiting. An esophagogastroduodenoscopy showed stenosis of the second portion of the duodenum and an impacted living round worm in the ampulla of Vater. The round worm was extracted with a snare without any complications, and the patient received albendazole treatment. A pathological examination of the stenotic portion of the biopsy specimen revealed chronic inflammation with eosinophilic infiltration throughout the mucosa. The patient remained asymptomatic at a follow-up examination. Duodenal stenosis should be considered in the complications of ascariasis, particularly in areas where this parasitic infestation is endemic.

Hypertensive Heart Failure Associated with Middle Aortic Syndrome Reversed Dramatically by Endovascular Management

A 42-year-old male patient presented with refractory hypertension and congestive heart failure. He had taken hydrochlorthiazide 50 mg, carvedilol 25 mg, diltiazem 180 mg, and losartan 100 mg per day. Aortogram revealed a severe luminal narrowing in the distal thoracic aorta with a peak systolic pressure gradient of 60 mmHg across the lesion. Endovascular management was performed with 22 x 80 mm self-expandable Nitinol-S stent after predilation with 10 x 40 mm balloon. After endovascular management, the patient's blood pressure, left ventricular ejection fraction (LVEF) and dilated LV dimension were remarkably improved.

Improvement of Severe Tricuspid Regurgitation with Right Heart Failure Associated with Thyrotoxicosis due to Graves' Disease

Hyperthyroidism can be a cause of congestive heart failure. Left heart failure is occasionally complicated in patients with hyperthyroidism. However, predominant right heart failure without LV systolic dysfunction rarely develops in patients with hyperthyroidism. We present herein a case of reversible severe tricuspid regurgitation with predominant right heart failure associated with thyrotoxicosis.

Anomalous Origin of the Right Coronary Artery From the Main Pulmonary Artery Presenting as Angina Pectoris in an Adult

The anomalous origin of the right coronary artery from the main pulmonary artery has been rarely reported. We report a 63-year-old male with angina pectoris who was shown to have an anomalous origin of the right coronary artery from the main pulmonary artery. The abnormal origin was identified by conventional coronary angiography, but the abnormal course of the artery was precisely delineated by high resolution multi-slice computerized tomography. The patient underwent successful surgical correction of the anomalous vessel with complete resolution of symptoms.

A Case of Acute Lower Gastrointestinal Bleeding from a Benign Appendiceal Ulcer / 대한소화기내시경학회지

A hemorrhoid is the most common cause of acute lower gastrointestinal (LGI) bleeding. Diverticulosis, angiodysplasia and ischemic colitis can also cause LGI bleeding. Acute LGI bleeding from the appendix is very rare. We experienced a case of a 33-year-old woman with acute LGI bleeding from the appendix. Colonoscopy demonstrated an active hemorrhage from the orifice of the appendix. The patient was treated with a appendectomy, and a histological examination showed the presence of a small ulcer with inflamed granulation tissue in the mucosa and submucosa.
