COX-2 inhibitors for pain-relief?

EurekAlert has a release about the results of two research programs into the use of COX-2 inhibitors by people with IBD:

Both studies examined the benefits of non-steroidal anti-inflammatory drugs (NSAIDs), including COX-2 inhibitors, in a patient population with ulcerative colitis and/or Crohn's disease. Study findings show that NSAIDs were well-tolerated, with COX-2 inhibitors offering the most effective pain relief in this group.

MedPage Today has another summary:

... these studies imply that NSAIDs -- long thought to be absolutely contraindicated for patients with inflammatory bowel disease -- can be used safely in some circumstances
