The Surgeon

Administration of omega-3 fatty acid supplements did not appear to improve the rate of relapse in patients with Crohn’s disease, according to a study released on April 9, 2008 in JAMA.

Crohn’s Disease is a gastrointestinal disorder which is indicated by chronic inflammation of the wall of the digestive tract, usually in the ileum or large intestines. The disease involves constant cycles of flare-ups and remission throughout the life of the patient, and without proper treatment, must be addressed surgically. It is considered an inflammatory bowel disease (IBD), similar to ulcerative colitis. Therapy to induce remission in Crohn’s disease is an unmet medical need, usually attempted with the use of certain immunosuppressive drugs, which are associated with infection and other risks. Many Crohn’s patients turn to alternative medications in the face of disappointing overall results.

Sonoenteroclysis, a new sonographic method in evaluating and diagnosing small bowel disorders is an effective alternative to the usual method of barium enteroclysis, according to a recent study conducted by researchers at the Postgraduate Institute of Medical Education and Research in Chandigarh, India. Sonoenteroclysis is a new way of doing transabdominal ultrasound. Patients are given fluid through the nasojejunal tube in order to alleviate gas in the bowel.

Scientists have for the first time discovered that people with the same cancer susceptibility genes respond differently depending on their race. Their results are published in Nature Genetics* .

The team from the University of Edinburgh has shown that a genetic marker is associated with an increased the risk of colon cancer in Europeans, but not in the Japanese population. But this genetic variant was associated with a similar risk of rectal cancer in both populations.

While dietary differences are already well known to be important, this discovery shows for the first time that genetic factors might explain some of the differences in bowel cancer risk between populations**.
