Therapeutic ERC using a SBE for patients with R-Y anastomosis is considered to be safe and effective. A short SBE appears to be promising for further improvement in therapeutic results.

We report a case of mesenteric chylous cyst diagnosed preoperatively by ultrasonography (US) and computed tomography (CT). Both demonstrated a unilocular cystic mass with a fluid-fluid level. The CT number of the two components indicated fat density and water density and with shaking or positional changes, the contents displayed miscibility. The tumor changed its position during hospitalization. Both features are considered to be quite diagnostic of this condition.

DWI can contribute to the improvement of the diagnostic capability for gallbladder wall thickening or polypoid lesions by compensating for weaknesses of other modalities by its many advantages, although cases with acute cholecystitis or such history sometimes show false-positive on DWI.

CE-CT may play a complementary role to colonoscopy in patients with suspected CDB, but is not recommended for all cases due to its low detection rate. Patients who can be examined within 2 h of last hematochezia would be candidates for urgent CT.
