Background & Aims: Since 1980, we have followed 259 patients with chronic Crohn's colitis in a prospective colonoscopic surveillance program. Our initial results through August 1998 showed a 22% chance of developing definite dysplasia or cancer by the fourth surveillance examination. We now update the results of all examinations since September 1998 until April 2005.

Colonoscopic polypectomy continues to be a major activity of gastrointestinal endoscopists, based upon the belief that ridding the colon of polyps prevents colon cancer. We review recent literature bearing on this assumption, emphasizing the benefits and limitations of colonoscopy for screening and surveillance of polyps. CT colonography has developed as an alternative or adjunct to colonoscopy but has not surpassed it in accuracy or therapeutic potential.

Objectives: We reviewed data to investigate the effect of 5-ASA drugs, metronidazole, ciprofloxacin, prednisone, 6-mercaptopurine, azathioprine, and cyclosporine on pregnancy outcomes in patients with inflammatory bowel disease (IBD).

Methods: One hundred and thirteen female patients with a total of 207 documented conceptions were studied. Treatment information included: smoking history (patient and spouse), dates of conception and termination, and outcome of pregnancy (spontaneous abortion, therapeutic abortion, maternal or fetal illness resulting in abortion, premature birth, healthy full-term birth, multiple births, ectopic pregnancy, congenital defects), weight of baby, type of delivery (cesarian section, vaginal), medication history during each trimester (mean dose, maximum dose, frequency).

Endoscopic therapy can be employed and may be useful in inflammatory bowel disease patients with dysplastic polyps, inflammatory strictures (enteric and biliary), bleeding, and for treatment of some complications of continent ileostomies. Dysplastic polyps can be removed endoscopically safely and effectively without resorting to colectomy, as long as there is no other detectable dysplasia in flat mucosa and complete removal can be assured (by biopsy of adjacent mucosa and close follow-up). Some colonic strictures in Crohn's disease can be dilated using endoscopes of graded caliber or with through-the-scope balloons, with or without stent placement.
