Evaluating the Optimal Timing of Trans-Anal Irrigation for Low Anterior Resection Syndrome Post-rectal Cancer Surgery (EARLY-TAI)

8 luglio 2026 aggiornato da: Simona Ascanelli

Evaluating the Optimal Timing of Trans-Anal Irrigation for Low Anterior Resection Syndrome Post-rectal Cancer Surgery - An Italian Multicentre Randomised Study

This study aims to evaluate the optimal timing of trans-anal irrigation (TAI) for participants with low anterior resection syndrome (LARS) who have undergone surgery for rectal cancer.

The main question it aims to answer is:

"Can starting TAI within three months of stoma closure reduce the number of daily bowel movements in people who have undergone rectal surgery?" Researchers will compare the outcomes for participants who start TAI within the first three months with those who start after three months, to see if early TAI can reduce the number of daily bowel movements more effectively than starting later.

The study will also determine whether early TAI can improve typical bowel symptoms, enhance quality of life, and increase satisfaction with treatment as much as when it is performed more than three months after stoma closure.

Participants will:

  • Undergo a preliminary visit to assess their eligibility to participate
  • Undergo training to understand how to use the device correctly
  • Perform regular TAI
  • Undergo four control visits at 1, 3, 6 and 9 months after the start of treatment.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Early TAI-treated group
This arm will start trans-anal irrigation within 3 months after stoma closure
The procedure involves the introduction of water into the rectum and colon via the anus, which stimulates colonic reflex activity and acts as a mechanical bowel washout, thereby facilitating faecal evacuation. The device will deliver a controlled amount of warm water using a catheter - cone or balloon catheter - while sitting on the toilet. Once the desired amount of water has been introduced, the patient will expel the water and bowel contents. The procedure will take approximately 15-30 minutes, depending on the individual patient's response.
Altro: Late TAI-treated group
This arm will begin trans-anal irrigation between three and six months after stoma closure

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Compare the effectiveness of two treatment regimens, initiated within different time frames following ostomy closure, in reducing the number of bowel movements in 24 hours.
Lasso di tempo: From baseline to 3 months
The difference in the change from baseline (V0) in the number of bowel movements (i.e. defecations) in 24 hours at 3 months after stoma closure (V2) between the early TAI group and the late TAI-treated group.
From baseline to 3 months

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Efficacy of early administration of TAI in reducing the symptoms of LARS in the longterm period (up to 9 months).
Lasso di tempo: From baseline to 9 months
The difference in the change from baseline (V0) in the number of bowel movements in 24 hours at 6 and 9 months (V3 and V4) after stoma closure between the early TAI group and the late TAI-treated group.
From baseline to 9 months
Efficacy of early administration of TAI in prevent LARS chronicity (prevent the increase of specific symptoms of LARS at all time points).
Lasso di tempo: From baseline to 9 months
The difference in the change from baseline (V0) in the Low Anterior Resection Syndrome (LARS) score (with a focus on the individual components of fecal urgency, incontinence, and incomplete evacuation) at various time points (V2, V3, V4) between the two groups (early TAI and late TAI-treated group). The LARS score ranges from 0 to 42 points. Patients are classified into one of three categories: no LARS (0-20 points), minor LARS (21-29 points) or major LARS (30-42 points).
From baseline to 9 months
Efficacy of early administration of TAI improving quality of life at all time points
Lasso di tempo: From baseline to 9 months
Changes in quality of life (QoL) scores (across all domains of the Short Form-36 (SF-36) questionnaire) from baseline (V0) at all time points (V2, V3 and V4), and an evaluation of differences between the two groups. SF-36 scores for each domain range from 0 to 100, with higher scores indicating a more favourable health state.
From baseline to 9 months
Efficacy of early administration of TAI improving patient satisfaction at all time points
Lasso di tempo: From baseline to 9 months
Change in patient satisfaction at all time points from baseline (V0) using a visual analogue scale (VAS), and evaluation of the differences between the two groups. The VAS consists of a 10 cm line with two endpoints representing 0 = completely unsatisfied and 10 = completely satisfied.
From baseline to 9 months
Evaluate how various factors, such as the timing of TAI initiation, type of anastomosis, prior neoadjuvant radio-chemotherapy, and other patient baseline characteristics, influence LARS symptoms
Lasso di tempo: From baseline to 9 months
The variation in Low Anterior Resection Syndrome (LARS) scores in relation to factors such as the time at which TAI was initiated, the type of anastomosis, previous neoadjuvant radio-chemotherapy, and other baseline patient characteristics in the two groups was examined. The LARS score ranges from 0 to 42 points. Patients are classified into one of three categories: no LARS (0-20 points), minor LARS (21-29 points) or major LARS (30-42 points).
From baseline to 9 months
