Objective: Some patients (10 % - 32 %) with a positive guaiac fecal occult blood test (gFOBT) do not undergo the recommended colonoscopy. The aim of this study was to compare video capsule endoscopy (VCE) and computed tomography colonography (CTC) in terms of participation rate and detection outcomes when offered to patients with a positive gFOBT who did not undergo the recommended colonoscopy.
Methods: An invitation letter offering CTC or VCE was sent to selected patients after randomization.
Unlabelled: Colonoscopy is currently the reference method to detect colorectal neoplasia, yet some adenomas remain undetected. The water infusion technique and dying with indigo carmine has shown interesting results for reducing this miss rate. The aim of this study was to compare the adenoma detection rate (adenoma and adenocarcinoma; ADR) and the mean number of adenomas per patient (MAP) for blue-water infusion colonoscopy (BWIC) versus standard colonoscopy.

Aim: The aim of this study was to evaluate the prevalence of primary sclerosing cholangitis and other histological liver abnormalities in patients operated on for ulcerative colitis and to discuss the advantages of performing a systematic liver biopsy during surgery.
Methods: From 1996 to 2001, 21 consecutive patients underwent a restorative proctocolectomy or a reoperation after proctocolectomy for ulcerative colitis. These patients systematically underwent liver biopsy during the procedure.
