Hi I had a sigmoidoscopy last month for rectal bleeding. A surgeon performed the procedure and found diverticula. The bleeding continued and I was referred for a colonoscopy which I had on Wednesday. I mentioned the diverticula to the nurse endoscopist who was performing the procedure and she said there were none. I can't see how they disappeared in three weeks and it has made me worried. I suffer from health anxiety anyway and now it's completely in full swing as I think she may have missed other things. I didn't ask at the time why she had missed the diverticula (sedation just made me happy that I had been given the all clear) but now I'm getting more worried by the day.
Has anyone had similar experience? Or does anyone know why this could have happened? Not sure what to do now 
Hi Stella
I am sorry to hear you are so worried, I suffer from health anxiety too, so I know how stressed you must feel. I have never heard of diverticula, so I don't know what it is. But if you had a colonoscopy and they found something sinister they would have told you there and then. This seems to be common practice. I would suggest try not to worry because if you had a cancerous growth (and I am sure this is your concern) you would have had a follow up by now. I was told immediately about a suspicious tumour, and a very fast follow up appointment confirmed I have cancer. I am still reeling from the shock. Treatment for me is to start soon, all this has happened to me within the space of two weeks. Please try not to worry, because I would say it's looking good for you.
I wish you luck

I would go to see my GP. There is some for the rectal bleeding and if they have given you a colonoscopy it ought to have been apparent. If you are booking your GP appointment worth checking with the receptionist that the Dr has received the letter from the hospital. I think that most usually rectal bleeding is not sinister, so you can relax, now find out what can be done about the bleeding. Your doctor might suggest diet and/or fibre?
Presumably you will have a follow up consultation with the consultant if the bleeding is continuing if not see your GP for a referral. The consultant will have the video of the procedure to look at. The colonoscopy is the gold standard investigation and any diverticula would be very apparent. The colonoscopy is the procedure that you should trust over the sigmoidoscopy that does not see far into the colon.
I have had diverticuli for over thirty years going from slight pocketing to widespread. I get bleeding on a very ocasional basis and have been lucky that I have not had any infections or fever.
Do you get any pain? Diverticulitis is often described as 'left sided appendicitis' as it can be a similar type of pain.
I called the dept and spoke to the nurse who was very defensive, I just wanted an answer as to why the diverticular were there on the sigmoid and not on the colonoscopy. She couldn't answer that. I've got a gp appointment on Tuesday so I will ask then. Also back to chasing clinic appointment for an answer from the consultant. I'm trying not to worry but it's hard when you don't understand how one person can see one thing and then another can't see it at all. At this point I'm considering asking for a second colonoscopy just to settle things
Thanks for your reply Margaret. I truly hope that everything is ok for you ((hugs))
There is also a non invasive Virtual Colonoscopy (CT Scan) that shows everything in great detail. I would demand that. You still need to take the laxative but it is much safer, no chance of internal damage from the probe or as in my case the vagus nerve being stimulated and my BP and heart rate dropping and going into atrial fibrllation.
A lot of tests produce false positives but a visual procedure shouldn't.
Hi Stella. Phone up and make an appointment to see your consultant. Say you are not happy that you have been given contradictory results and need the reason explained to you
