Late-Onset Primary Intestinal Lymphangiectasia Successfully Managed with Octreotide: A Case Report

抄録

We report a case of a patient with late-onset primary lymphangiectasia whose persistent diarrhoea was successfully managed with octreotide. A 63 year-old man visited our clinic with a complaint of worsening general edema. Gastrointestinal endoscopy revealed typical whitish jejunal villi, which suggested primary intestinal lymphangiectasia. Despite a diet, supplemented with medium-chain triglycerides; antiplasmin therapy; oral corticosteroids; and surgery, including pericardial window and lymphaticovenous anastomoses; his symptoms, including watery diarrhoea, showed no improvement. After administration of octreotide, his persistent diarrhoea resolved within a couple of days. Octreotide was continued for 2 months. Thereafter, his diarrhoea has not recurred for 6 months.
