A total of 31 participants were assessed for eligibility and ten were found to be eligible. Main medical reasons for exclusion were suspected malignancy (n = four), asthma (n = four), and history of trouble with bowel preparation in earlier colonoscopies (n = two). Among the ten eligible participants, two declined to participate, while the remaining eight participants were included and completed the trial, between 26. October 2021 and 4. April 2022. The study population consisted of three men and five women with median age 67 years. Dilution of CF at 1:2 in water resulted in similar shear viscosity to FMT.Proportion of participants with CF visualization in the cecum were 100% after colonoscopy, 50% after enema + and 38% after enema ÷ (Fig.

X-ray pictures from two study participants after colonoscopy, enema (-) and enema (+), created with BioRender.comAll participants tolerated the enema procedure well and there were no adverse events. One of the participants experienced some soiling of CF after the enema insertion, before the first X-ray was performed. During digital exam before enema insertion the sphincter tone was identified as weak. CF was still visualized in the patient’s cecum in both X-ray images.
