Aseptic abscesses are rare, culture-negative abscesses associated with inflammatory bowel disease which arise most commonly in solid abdominal organs including the spleen, liver, and lymph nodes [1] [2]. Bacterial and aseptic splenic abscesses may not be treatable with antibiotics and corticosteroids alone and require drainage or splenectomy. We report successful endoscopic ultrasound-guided transmural drainage (EUS-TD) of an aseptic splenic abscess.

Our colleagues reported the case of a 41-year-old woman with ulcerative colitis complicated by pyoderma gangrenosum, multiple renal abscesses treated by percutaneous drainage, and a splenic abscess [3]. The splenic abscess measured 4 × 4 × 4 cm on imaging studies ([Fig. 1]). Because the splenic abscess was refractory to medications and could not be approached percutaneously, EUS-TD was performed ([Video 1]).

Quality:

A forward-viewing endosonoscope (TGF-UC260 J, Olympus Corp., Tokyo, Japan) was used to puncture the gastric fundus with a 19-gauge needle (EZ Shot 3 Plus, Olympus) under endosonographic and fluoroscopic guidance ([Fig. 2a–d]). A guidewire was advanced into the abscess and the puncture site was dilated with a biliary balloon dilator. An Uneven Double Lumen Cannula (Piolax Medical Devices, Kanagawa, Japan) was used to introduce a second guidewire. A 4-cm, 7 Fr pigtail stent was placed over the first guidewire, while a naso-abscess drainage tube was inserted over the second guidewire ([Fig. 2e, f]). Follow-up abdominal ultrasound showed a shrunken abscess ([Fig. 3]). The naso-abscess tube was removed after cultures of the aspirate were confirmed to be negative. No recurrence was observed during 12 months of follow-up.

There have recently been several reports of successful EUS-TD for subphrenic abscesses, including one report of EUS-TD for a splenic abscess that arose as a complication of acute pancreatitis [4] [5]. EUS-TD may be an attractive option for splenic abscesses because they are often difficult to access percutaneously and are frequently refractory to medical treatment alone.
