Pancolitis literally means colitis of the entire colon. 'pan' refers to the extent, not type, of colitis, so your diagnosis hasn't changed: it's still ulcerative colitis. Pancolitis can range from mild to severe, like the more limited left-sided colitis. What it means for your health is hard to say. It depends on how severe the inflammation is, and how easy it is to get under control with medication. The Remicade will hopefully start working for you after one or two more infusions.
And just in case you're not sure what left-sided colitis is, it's colitis of the descending (i.e. the left side) colon. UC typically affects the rectum and descending colon, but in some cases it can spread throughout the whole colon.
