Frank,
My husband never developed a leakage from his colon resection (he had cancer removed from the sigmoid and from the hepatic fissure, so he actually had two resections in one operation). So, though this is a problem, not everyone develops this complication. Also, much depends on the age and overall health going into this whole ordeal (i.e., how well you heal). Talk this over with your doctor as he should be able to give you a better idea, given that s/he likely has a better idea and more familiar with your overall health (and things like blood count) than anyone here. So, just take it one day at a time and stay in close touch with your doctor (also, don't lift anything heavier than say, 2 quarts of milk, for quiet a while).
Good luck!
