Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study is a multicentre randomized controlled trial with the objective to compare the effect of transanal irrigation with glycerol suppositories in patients suffering from major Low Anterior Resection Syndrome (LARS).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Transanal irrigation

Participants receiving TAI will irrigate once/day with stepwise volumes; 1. month 150 ml, 2. month 300 ml, and 3. month 500 ml.

Group Type EXPERIMENTAL

Qufora Irrisedo Cone System

Intervention Type DEVICE

The system works by connecting a tube from a water bag to a cone. The cone is placed into the rectum and the prescribed water volume is pumped into the rectum. When the water has been installed the valve is closed and the cone removed. Residual water and stool will then flow into the toilet.

Glycerol suppositories

Participants treated with glycerol suppositories will administer one glycerol suppository once/day.

Group Type ACTIVE_COMPARATOR

Glycerol "OBA"

Intervention Type DRUG

Rectal suppository. Stimulates the rectum and softens and loosens stool.
