“…The granules are suspended in sterile water prior to use, shaken vigorously for about 10 s, and then allowed to equilibrate for 2 min. During this process some of the particles disaggregate, forming microbubbles, which are stabilized by the layer of palmitic acid [8,9]. Levovist is available in 2.5-g and 4-g vials.…”

“…Recently, a new contrast-enhancing agent (SHU 508A) designed for Doppler US has been developed. It has also proven useful for the evaluation of tumoral vascularity (11). Endosonography (EUS) is also valuable for the differential diagnosis of submucosal tumors (12).…”

KEY WORDS: gastrointestinal stromal tumor; ultrasonography; double-balloon enteroscopy; contrast-enhancing agent.Gastrointestinal stromal tumors (GISTs) in the small intestine are rare and are sometimes incidentally detected by sudden gastrointestinal bleeding. The patients often undergo surgery without an accurate diagnosis, because most of these lesions are inaccessible by conventional endoscopy. Ultrasonography (US) has become an effective diagnostic modality for gastrointestinal diseases. In addition, recent studies have revealed that the microcirculation of the gastrointestinal wall can be assessed by contrastenhanced imaging using the agent SHU 508A (Levovist; Schering, Berlin, Germany) (1, 2). However, there have been few reports of the sonographic features of GISTs. We report a patient with GIST in the jejunum that was diagnosed by US as a screening tool and that was confirmed preoperatively by double-balloon enteroscopy. CASE REPORTA 75-year-old man was admitted to our hospital because of general fatigue. On hematologic testing, carcinoembryonic antigen (CEA) was slightly increased (7.8 ng/ml), but results of other examinations were normal. He was 159 cm in height and 60 kg in weight, with stable vital signs. Routine abdominal US performed using the SSA-390A system (Toshiba, Tokyo), with 3.5-MHz curved and 7.5-MHz linear array transducers, showed a solid mass with an uneven irregular surface and clear boundaries,

“…Other agents have been developed for extravascular applications. 8 Currently, there are no contrast agents available to specifically enhance the visibility of the biliary tract on sonograms. Theoretically, the biliary tree is not accessible to microbubblebased contrast agents.…”

Cholangitis rarely occurs after sphincteroplasty if there is no biliary obstruction. We report the case of a patient who developed recurrent cholangitis despite having a patent biliary tract after sphincteroplasty. Duodenobiliary reflux was demonstrated on sonography after enhancement of the reflux flow with a novel oral contrast agent, a carbonated soda beverage. Sonography with contrast enhancement provided by soda solution may prove satisfactory to detect duodenobiliary reflux after sphincteroplasty safely, effectively, and economically.
