This is a case of a successful CT-guided drainage procedure for a patient who underwent total gastrectomy and splenectomy for a gastrointestinal stromal tumor (GIST).

The patient developed two intra-abdominal collections following the operation. Improvement was reflected by the reduction of the collection size and the decreased leukocytic count. Percutaneous image-guided drainage should be considered the first line of treatment for postoperative collections, as surgery is often tough in the early postoperative period.
