A Case of Massive Hematochezia from a Meckel's Diverticulum without Ectopic Mucosa / 대한소화기내시경학회지

Meckel's diverticulum, which is a persistence of a remnant of the omphalomesenteric duct, is the most common developmental anomaly of the gastrointestinal tract, with an incidence of about 2% in the general population. Typically, Meckel's diverticulum is a true diverticulum because it arises from the antimesenteric border of the small bowel and all layers of the intestinal wall are present. Complications of Meckel's diverticulum include bleeding, perforation, diverticulitis, intestinal obstruction, stones, intussusception, hernia, and neoplasm. Bleeding in particular is a common complication and has always been caused by an ulceration of the ileal mucosa adjacent to the acid-producing ectopic gastric mucosa in a Meckel's diverticulum. A case was recently experienced involving massive hematochezia from Meckel's diverticulum without ectopic gastric mucosa in a 27 year-old woman, and in herein reported.

A Case of Hypereosinophilic Syndrome with Hepatic and Gastrointestinal Involvement / 대한간학회지

Hypereosinophilic syndrome is characterized by prolonged eosinophilia of blood and tissue without an identifiable underlying cause and multiorgan system dysfunction by eosinophil-related tissue damage to variable organs: liver, heart, lung, kidney, gastrointestinal tract, skin, nerve. Some case of hypereosinophilic syndrome with hepatic and gastrointestinal involvement have been reported, but not much. We are reporting a case of hypereosinophilic syndrome with hepatic and gastrointestinal involvement in 56-year-old man who presented general weakness and epigastric discomfort. In abdominal US, CT and MRI, intrahepatic multifocal ill-defined lesions were detected. The patient was treated with prednisolone for 16 weeks and recovered from eosinophilia and gastric involvement. A gastric biopsy was taken to confirm recovery. Also, the ill-defined lesions in US and CT disappeared after treatment.
