主膵管と交通のある巨大膵仮性嚢胞がエコーガイド下経皮的ドレナージで消失した1症例

Abstract

A 37-year-old man was referred to our hospital because of left hypochon- dralgia. He was diagnosed as having chronic pancreatitis with a pancreatic pseudocyst, measuring approximately 8×1O×12 cm, located in the pancreatic tail. After two weeks of conservative medical treatment, the pancreatic pseudocyst had not decreased in size and left hypochondralgia persisted. We then performed percutaneous aspiration and drainage of the cyst guided by ultrasonography. A brownish fluid, 600 ml in volume, was aspirated and the cyst disappeared completely about three months after the drainage. On the basis of a review of the literature and our own experience, we believe that percutaneous drainage should be a first choice for the management of pancreatic pseudocysts that require inter- ventional therapy.
