Senna and Moviprep fails repeatedly to clear the bowel

Hi all, 

So I have had three colonoscopies in a row in all of which the colonoscopist could not see the bowel because the moviprep had failed.

The last two colonoscopies were on extended prep with a 10 day low residue diet 7 days of Senna laxatives 1 day liquid diet and 3 sachets of Moviprep. 

Neither the laxatives nor the senna cleared the bowel. 

What seems to be happening is that my bowels shut down when I go on the low residue diet as I normally have a high fibre diet and on this I have no problem with bowel movements.

The colonoscopist found what he said was probably cancer through digital rectal examination.

My screening nurse tells me that they have no possibility of any alternative bowel preps so I have to make the moviprep work if I need surgery.

Does anyone have a similar experience of repeated bowel prep failure? If so I would be interested if you found  a way to make it work.

Thank you

  • I had the same problem but wasn't told to change my diet. The Moviprep didn't work at all so they gave me a different one, which I thought had worked but in realty hadn't. The Colonoscopist(?) persisted with gritted teeth whilst I climbed the walls but he succeeded in achieving a result, which was correct. Now I have two stomas and routine checks are carried out via my colostomy, with no bowel prep required as my ileostomy does all of the dirty work.

    Curiously., the best laxative I have found post-surgery is 2 pints of Stowford Press dry cider. Scary!

  • Have they not offered Plenvu as an alternative? My first colonoscopy was with Plenvu and gave a good result. For my surgery, I had Moviprep which was pretty useless as I threw most of it up. Because of that I was really concerned that surgery wouldn't go ahead but my CRN said not to worry as bowel surgery is often carried out as an emergency, so no prep in advance for those circumstances, and they have procedures in place to allow for that.

    Had another colonoscopy recently for which the prep was a phosphate enema done at home plus another immediately before the procedure (as I have an ileostomy). Results were rapid and explosive - even although the large bowel hadnt been in use for 4 years. No low residue diet required. 

    I'm not sure if any of this is helpful apart from the fact that a failure of bowel prep wouldn't necessarily prevent surgery. Hopefully you can get some clarification from your consultant should surgery be in the pipeline.

    Hope it all works out well.

  • Thanks Dulac. I love the Cider as a laxative that cracked me up. Great to hear your experience

  • Thanks BlueBlue, No no Plenvu, enemas or anything else they simply grimly persisted with Moviprep despite the obvious fact it was repeatedly failing. Hopefully the consultant will offer me alternatives later on. I can assure you that was all very helpful as I didn't know stuff like the fact that bowel surgery can be done without prep. 

  • I'm in Spain and I had to take Citrafleet (I'm not sure its available in the UK). 2 sachets one in the evening and one 6 hours before the Colonoscopy. The first sachet kicked in at midnight. I threw up most of the second one but by then the results had already been explosive and continuous. I got the top score for cleanliness and I'm still proud of that. :-). Unfortunately they found a malignant tumour. I go in for surgery on Monday. The surgeon is using an enema once I'm asleep rather than me prepping. I pity the poor nurse who gets to sort out the results of that. 

  • I also live in Spain, and get given Citrafleet for colonoscopy and surgery prep. Has always worked thus far

  • It looks as though it’s available in U.K. too

  • Hi Kaza thanks for that and I hope that your surgery goes really well for you
