Comparison of Transanal Irrigation and Glycerol Suppositories in Treatment of Low Anterior Resection Syndrome

Transanal irrigation (TAI) is used as a second-line treatment following unsuccessful personalised conservative treatment (PCT) of LARS. However, it is unknown if scheduled, initiated defecation with the aid of a glycerol suppository will have the same clinical effect as TAI. Thus, the aim of this study is to compare the effect of TAI with a glycerol suppository in patients suffering from major LARS. The study is a multi-centre, randomised, controlled, 12 weeks, parallel-group trial comparing treatment with TAI to treatment with glycerol suppositories. Patients will be randomised - stratified by centre and neoadjuvant radiotherapy - in a 1:1 ratio to receive treatment with TAI or glycerol suppositories. Primary endpoint will be assessed by the end of week twelve.
