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).
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.

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

RECRUITINGBowel function, change in symptom 1 score assessed using the Measure Yourself Medical Outcome Profile (MYMOP2) Score.
MYMOP2 is a validated problem-specific, patient-generated questionnaire. Patients are asked to specify one or two symptoms that concern them the most. Subsequently they evaluate the severity on a 7-point Likert scale. The second part of the questionnaire uses the same scale to assess whether the symptom limits or prevent any daily activity, and also to rate general well-being. Follow-up questionnaires address the original issues completed in the initial form. Symptom 1, symptom 2, activity, and wellbeing each have a separate score between 0 and 6 with 0 indicating "as good as it could be" and 6 "as bad as it could be". An overall score is calculated by taking the average of item scores.
Time frame: 12 weeks.

Bowel function assessed using the Low Anterior Resection Syndrome (LARS) Score.
The LARS score is a validated questionnaire for evaluation of bowel function after sphincter-preserving surgery. It covers five LARS symptoms including: incontinence for flatus, incontinence for liquid stools, frequency (number of daily bowel movements), clustering, and urgency. The scores from each five answers are added to one final score. The score ranges from 0-42 with 0 indicating the best score and 42 the worst. Based on the score patients are stratified into: 0-20: No LARS, 21-29: Minor LARS, 30-42: Major LARS.
Time frame: 4, 8, and 12 weeks.
Bowel function assessed using the Memorial Sloan-Kettering Cancer Centre Bowel Function Instrument (MSKCC BFI) Score.
The MSKCC BFI score is a validated questionnaire for evaluation of bowel function after sphincter-preserving surgery. It comprises 18 items covering the frequency of various LARS symptoms and is divided into three sub-scales and four single items. It is scored on a 5-point Likert scale ranging from "always" to "never". The sub-scales scores are summarised as: A 6-item frequency sub-scale (6-30), a four-item dietary sub-scale (4-20), and a four-item urgency sub-scale (4-20). A global score can be calculated as the sum of the sub-scale scores. A total score (possible score range 18-90) can be calculated by adding all the item scores (sub-scale scores plus single item scores). A higher score indicates better bowel function.
Time frame: 4, 8, and 12 weeks.
Frequency of bowel movements, incontinence episodes (total, passive, and urge), urge episodes, soiling, and daily gas incontinence, incomplete emptying, and average urge time assessed using the Journl A/S application.
Journl A/S has developed an application for evaluation of bowel function. The participants can enter real-time data into the application and data will be stored in a backend allowing calculations of frequencies and averages on these parameters during weeks 3-4, 6-8, and 11-12 in the study period.
Time frame: Weeks 3-4, weeks 7-8, and weeks 11-12.
Fecal incontinence assessed using the St. Mark's Incontinence Score.
The St. Mark's Incontinence score is a validated questionnaire for evaluation of fecal incontinence. It covers the frequency of three types of fecal incontinence: Solid, liquid, and gas and the consequences: Pad wearing or usage of a plug, and lifestyle alteration. Furthermore, it incorporates: urgency and the need for antidiarrheal drugs. For each item of fecal incontinence and lifestyle alterations the frequency option ranges from never (score 0) to daily (score 4). The rest of the items are scored as follows: Urgency: No (score 0) or yes (score 4), antidiarrheal drugs: No (score 0) or yes (score 2), pad wearing: No (score 0) or yes (score 2). The total score is the sum of each item. The minimum score is 0 = no incontinence and maximum score is 24 = totally incontinent.
Time frame: 4, 8, and 12 weeks.

Quality of life assessed using the EORTC Quality of Life questionnaire (QLQ)-C30.
The European Organisation for Research and Treatment of Cancer (EORTC) developed and validated a 30-item core questionnaire (QLQ-C30) reflecting global QoL in cancer patients. QLQ-C30 comprises five functional scales, three symptom scales, a global health scale/ a quality of life scale, and six single items. All the scales and single item measures range in score from 0-100. A high score represents a higher level of functioning, a high quality of life, and a greater degree of symptoms.
Time frame: 12 weeks.

QLQ-CR29 is developed by The European Organisation for Research and Treatment of Cancer (EORTC). It is a validated supplement to the QLQ-C30 specifically designed for assessment of quality of life in colorectal cancer patients. QLQ-CR29 consists of four functional scales and eighteen single items. All the scales range from 0-100. A high score represents a higher level of functioning and a greater degree of symptoms.
Time frame: 12 weeks.
Impact on quality of life and activities assessed using the Journl A/S application.

Quality of life and Health economics assessed using the European Quality of Life-5 Dimensions 5-level version questionnaire (EQ-5D-5L).
The EQ-5D-5L is a standardised measure of health status developed by the EuroQoL Group. It consists of a descriptive system and a EQ Visual Analogue scale. Each dimension in the descriptive system has five levels: No problems, slight problems, moderate problems, severe problems, and extreme problems. Each dimension is referred to in terms of a 5-digit code. The EQ Visual Analogue scale records the respondent's self-rated health on a vertical scale ranging from 0-100 where the endpoints are labelled "best imaginable" (100) and "worst imaginable" (0). The EQ-5D-5L can be converted into an index value which facilitates the calculation of quality-adjusted life years (QALYs) that are used in economic evaluations of health care interventions.
Time frame: 12 weeks.
