Endoscopic ultrasound-guided drainage of postoperative intra-abdominal abscesses

Figure 4 Case 4. A: Computed tomography (CT) reveals fluid collection at the dorsal side of the fornix close to the gastric wall; B: Endoscopic ultrasound (EUS) showing the fluid collection, which was punctured by a 19-gauge needle; C and D: Fluoroscopy image showing placement of the percutaneous drain and insertion of the 6-mm balloon catheter over the guidewire. Both a 7-Fr double pigtail stent and a 6-Fr nasal biliary catheter are placed; E: Ten days after EUS-guided drainage, CT reveals that the fluid collection decreased.
