Figure 3 Computed tomography findings in a 75-year-old man with recurrent gastric cancer. A: Preoperative computed tomography (CT) showed significant dilation with visible gas and effusions; B-D: Anteroposterior radiographs during the percutaneous procedure and suction under imaging guidance; E: At the end of aspiration, gas and effusions were significantly reduced; F: Postoperative CT showed that the intestine had returned to normal.
