• Conditions: Fecal Incontinence; Constipation
• Interventions: Device: Low-volume irrigation

• Registration Number: NCT05773742
• Lead Sponsor: Aarhus University Hospital

Brief Summary

The aim of this study is to investigate the efficacy of low-volume irrigation on bowel function among patients with fecal incontinence and/or chronic constipation (of heterogenous origin).

Detailed Description

The aim of this study is to investigate the efficacy of low-volume irrigation on bowel function among patients with FI and/or CC (of heterogenous origin). Further, the aim is to investigate if low volume irrigation can change the negative impact that symptoms of FI and/or CC (of heterogenous origin) have on the patients' daily activities and QoL. Additionally, the aim is to investigate the short-term and long-term discontinuation rates in relation to treatment with low-volume irrigation. Finally, the aim is to investigate the daily time-consumption, the practical challenges and the side effects related to low-volume irrigation. The study period is six weeks and the participants will be instructed to irrigate once daily with Qufora IrriSedo MiniGo.

This study is an interventional study. Patients with FI and/or CC of heterogenous origin, seen in the Nurse-led Clinic for Bowel Dysfunction at the Pelvic Floor Unit, Aarhus University hospital, will be included. Patients will be offered transanal irrigation as a treatment option. Patients presenting with Bristol stool type 6-7 should be offered conservative treatment to optimize the stool consistency. If patients can be regulated to a Bristol stool type 1-5, they can be invited to participate in the study. If necessary, regulation of the stool consistency in patients presenting with Bristol stool type 1-2 is an option, before introducing transanal irrigation.

Arm && Interventions

Group	Intervention	Description
Low-volume irrigation	Low-volume irrigation	The patients will be instructed to irrigate once daily at a fixed time for 6 weeks. The patients will be instructed to use the irrigation 30 min after breakfast, capitalizing on the gastrocolic response; however, should this not fit in with the individual's lifestyle, then an alternative time of the day may be used. Preferably shortly after a large meal. The patients should fill the pump with 180 milliliters (a full pump) and irrigate with a volume of 160 milliliters of water.

Primary Outcome Measures

Name	Time	Method
11-point Likert scale	6 weeks	The present bowel functions impact on daily activities (0: no, 10: maximum influence)

Secondary Outcome Measures

Name	Time	Method
11-point Likert scale	6 weeks, 3 months, 6 months, 12 months	General satisfaction with current treatment (0: perfect satisfaction, 10: total dissatisfaction)
The St. Mark's fecal incontinence score	6 weeks, 3 months, 6 months, 12 months	Participants suffering from fecal incontinence
The Fecal Incontinence Quality of Life Scale	6 weeks, 3 months, 6 months, 12 months	Participants suffering from fecal incontinence
PAC-SYM score	6 weeks, 3 months, 6 months, 12 months	Participants suffering from constipation
The Patients Assessment of Constipation Quality of life	6 weeks, 3 months, 6 months, 12 months	Participants suffering from constipation
The 5-level EQ-5D (EQ-5D-5L) index score	6 weeks, 3 months, 6 months, 12 months	For all patients
Discontinuation rates	6 weeks, 3 months, 6 months, 12 months	Time until discontinuation and reasons for discontinuation.
Correlation for the primary outcome	6 weeks	Correlation between score change in primary outcome and the patients' subjective perception of present bowel function rated on a 11-point Likert scale (0: no bowel dysfunction, 10: severe bowel dysfunction) and the patients' evaluation of the efficacy of low-volume irrigation on bowel function rated on a scale from great improvement to great worsening
Correlation for SMIS and PAC-SYM	6 weeks	Correlation between the SMIS or PAC-SYM and the patients' subjective perception of present bowel function rated on a 11-point Likert scale (0: no bowel dysfunction, 10: severe bowel dysfunction) and the patients' evaluation of the efficacy of low-volume irrigation on bowel function rated on a scale from great improvement to great worsening
Practicalities and adverse effects	6 weeks	Descriptive analyses of volume and duration of irrigation, efficacy of irrigation with regards to evacuation, practical challenges and adverse effects.
