Giant colonic diverticulum: percutaneous computed tomography-guided treatment.

We present a case of inflamed giant sigmoid diverticulum, which was treated under computed tomographic guidance by dilating the neck and decompressing the inflamed diverticulum. The procedure also involved placement of an internal stent across the neck of the diverticulum, the purpose of which was to decompress the giant diverticulum into the sigmoid colon and prevent acute recurrence. In patients with inflamed giant colonic diverticulum, the percutaneous approach may be useful in treatment of diverticulitis and avoiding a staged Hartmann procedure with end colostomy.
