Marilyn-I don't know what to tell you about the fluid and cysts. I'd be wrong to comment without being able to talk to and examine you and review the films.With respect to the incomplete colonoscopy, it is not unusual to not be able to completely traverse the colon with the scope. That happens probably <5% of the time. Reasons for this include a tortuous colon, adhesions, significant diverticular disease and bad preps. In these situations, advancing the scope may be difficult and pressing on may lead to colonic perforation. This does not mean that there is something necessarily wrong with your colon and it is not any type of diagnostic sign. It is usually the sign of a prudent gastroenterologist. If I can't see the whole colon with a scope, we go to barium which trickles easily around these areas [but as Chloe has found out, it doesn't always trickle back as easily).Hope it helps.
