Subacute Ischemic Colitis Developed after Severe Watery Diarrhea / 대한소화기내시경학회지

Ischemic colitis represents most common form of gastrointestinal ischemia, usually developed in elderly or debilitated patient with a variety of underlying medical problems. The presumed etiologies are numerous. It usually presents as an acute abdominal illness with bloody diarrhea. Subacute ischemic colitis in healthy adults develops spontaneously in the absence of major vasculature occlusion, and the original insult precipitating the ischemic event usually cannot be established. Diagnosis is based on the clinical symptom, barium study, colonoscopic and histopathologic findings. Therapy and outcome are depen-dent on the severity of disease. It usually requires only medical management and is asso-ciated a good prognosis. We report a case of subacute ischemic colitis in healthy adults developed after severe watery diarrhea with literatures.

A Case of Familial Adenomatous Polyposis (FAP) with A Large Sentinel Polyp / 대한소화기내시경학회지

Familial adenomatous polyposis(FAP) is a rare hereditary disorder characterized by the development of hundreds to thounds polyps throughout the colon and rectum. Moreover, several extracolonic manifestations are seen. Recently, this disease is recognized as a adenomatous polyposis syndrome which can involve the entire astrointestinal tract. Several reports have demonstrated a high incidence of gastroduodenal polyps in patients with familial adenomatous polyposis. These colon polyps can be eventually developed as colon cancer, if not be treated. So early diagnosis is needed and prophylactic surgery should be erformed. We experienced a case of familial adenomatous polyposis with a large sentinel polyp on the sigmoid colon, presenting hematochezia and mucoid diarrhea. He was early treated before progression to carcinoma by total colectomy, rectal mucosectomy and J pouch ileoanal anastomosis.
