Validation of TRansanal Irrigation Adherence scaLe (TRIAL)

Transanal irrigation (TAI) is a method used to empty stools from the recto-sigmoid and colon (from the descending colon to the transverse colon). It is recommended for treating evacuation disorders (bowel movements) or continence issues (fecal incontinence). It is a second-line treatment, offered after the failure of hygienic-dietary rules, perineal physiotherapy, and conventional drug treatments (suppositories, obturator plugs, etc.), in combination with treatments for transit constipation (hygienic-dietary rules and laxatives) if necessary.

The effectiveness of TAI has been widely demonstrated, particularly in neurological populations (spinal cord injuries, spina bifida, multiple sclerosis, etc.), but also in non-neurological populations, with a significant reduction in symptoms (constipation or incontinence) and an improvement in quality of life compared to medical treatment Despite demonstrated effectiveness with a long-term success rate of 50% among users, only 42% of patients continue use 21 months after learning the technique.

The aim of this study is to validate a tool for assessing patient adherence to the TAI device in order to identify non-adherent patients and subsequently determine the reasons for non-adherence to optimize treatment, in the absence of non-surgical therapeutic alternatives

The primary objective of this study is the psychometric validation of a transanal irrigation adherence self-questionnaire scale (TRIAL) in French.

The secondary objectives are assessing : 1/ correlation between the final score of TRIAL with sides effects reported, the using modalities, indications of this treatment, and patient's satisfaction. 2/ quality of life of these patients using the Transanal irrigation device. 3/ correlation between the final score of TRIAL and stool diary in order to define the cut-offs of strong, moderate and low adherence of this scale.

Inclusions will be headed during a consultation or a one day follow-up hospitalization in a neuro-urology department. On this day, patients will have a medical consultation and data concerning medical history, treatments, pelvic disorders' characteristics and modalities of use of TAI will be recorded. The patient will also complete the following questionnaires: TRIAL, a numeric scale of TACI effectiveness, Kess, Wexner, STAR-Q (if diagnosed with multiple sclerosis), NBD (if spinal cord injury), which are symptom scores for ano-rectal disorders; PGI-Severity of ano-rectal disorders; PGI-Improvement of ano-rectal disorders with TACI; USP; I-CAS (if using self-catheterization); and a numeric scale assessing the impact of ano-rectal disorders on quality of life.

Then, at home, the patient will complete a diary detailing the frequency of TAI use over 15 days, along with a new TRIAL questionnaire on day 15, which will be mailed back using a pre-stamped envelope provided by the department.

The validation of this new scale about TAI's adherence is part of a will to standardize the evaluation especially in the use of this device in order to identify the difficulties encountered by patients within therapeutic education programs for learning this technique.
