Brief Summary:
A randomised trial testing the effect of percutaneous nerve evaluation and transanal irrigation on bowel function in patients after low anterior resection for rectal cancer.

Condition or disease Intervention/treatment Phase
Rectal Cancer Procedure: Percutaneous nerve evaluation Not Applicable

Detailed Description:

Patients will undergo anal physiological assessment and will then be randomized to either treatment arm. The first 12 weeks they will be optimized in the conservative treatment of their bowel function before beginning active treatment with TAI or PNE. After 8 and 4 weeks respectively, the treatment will stop and they will have a period of 4 weeks back on optimized conservative treatment before beginning active treatment in the other active arm.

Detailed records of bowel, micturition and sexual function and QoL will be obtained at regular intervals during the entire trial fase.


Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 14 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Treatment of "Low Anterior Resection Syndrome" by Percutaneous Nerve Evaluation and Transanal Irrigation. A Randomized Cross Over Study.
Study Start Date : January 2011
Estimated Primary Completion Date : December 2018
Estimated Study Completion Date : December 2019

Arm Intervention/treatment
Active Comparator: PNE first
patients randomised to start with PNE stimulation over 4 weeks. Then the stimulator will be removed and after a wash out period of 4 weeks they will be trained in transanal irrigation
Procedure: Percutaneous nerve evaluation
Implantation of a nerve stimulator to stimulate the sacral nerve plexus
Other Names:
  • The Peristeen Anal Irrigation System
  • Medtronic nerve stimulators

Active Comparator: TAI first
Patients randomised to start with transanal irrigation treatment in 8 weeks, thereafter a wash out period of 4 weeks before being implanted with a neuro stimulator
Procedure: Percutaneous nerve evaluation
Implantation of a nerve stimulator to stimulate the sacral nerve plexus
Other Names:
  • The Peristeen Anal Irrigation System
  • Medtronic nerve stimulators




Primary Outcome Measures :
  1. changes in LARS score [ Time Frame: baseline, 12, 16, 20, 24 and 28 weeks ]
    A symptom score ranging from 0 to 42 points calculated on the basis of bowel function


Secondary Outcome Measures :
  1. Sexual function [ Time Frame: baseline, 12, 16, 20, 24 and 28 weeks ]
    self-reported sexual function measured by validated questionnaires

  2. Bladder function [ Time Frame: baseline, 12, 16, 20, 24 and 28 weeks ]
    self-reported bladder function by validated questionnaires

  3. Incontinence [ Time Frame: baseline, 12, 16, 20, 24 and 28 weeks ]
    faecal incontinence measured by wexner score and St. Marks incontinence score

  4. Patient Satisfaction [ Time Frame: baseline, 12, 16, 20, 24 and 28 weeks ]
    patient satisfaction measured on a VAS
