Efficacy and Safety of Transcutaneous Posterior Tibial Nerve Stimulation on Fecal Continence in Patients Undergoing Surgery for Rectal Neoplasia
Randomized Clinical Trial Assessing the Efficacy and Safety of Transcutaneous Posterior Tibial Nerve Stimulation on Fecal Continence in Patients Undergoing Surgery for Rectal Neoplasia
Rectal neoplasia is one of the most prevalent cancers in Spain, and the treatment of choice is total mesorectal excision (TME), as it has demonstrated significant oncological improvements. However, mesorectal excision is not without complications, and patients often experience altered bowel function in the form of low anterior resection syndrome (LARS), as well as erectile dysfunction. However, few studies evaluate faecal incontinence, as most focus on oncological outcomes.
The aim of our study is to evaluate the efficacy and safety of posterior tibial nerve stimulation on fecal incontinence, sexual dysfunction, and quality of life in patients who underwent to rectal surgery for rectal neoplasia.
It will be conducted a randomized clinical trial (1:1) with two arms: half of the patients will receive posterior tibial nerve stimulation, while the other half will undergo stimulation with subtherapeutic doses. Faecal incontinence will be assessed using the LARS and Wexner questionnaires, and quality of life and sexual function will be assessed using the Fecal Incontinence Quality of Life Scale (FIQLS) and the Colorectal Cancer Quality of Life Questionnaire (QLQ-CR38), at one month, six months and one year after surgery.

Eksperimentell: Intervention group
Posterior tibial nerve stimulation with Beurer EM-49 digital neuroestimulator at complete doses
|
In the intervention group, Beurer EM-49 digital neurostimulator will be used, with CE marking, and a dose of 20 Hertz (Hz) - 200 microseconds (μs) will be applied. As the control group and the intervention group, the pelvic floor rehabilitator will program the neurostimulator for each case and then they will be trained on how to perform the neurostimulation. The first session will be carried out with the rehabilitator to learn how it works and resolve doubts about its use, and later the sessions will be carried out at home. In both groups, a program for carrying out sessions will be indicated according to the following scheme:

Sham-komparator: Control group
Posterior tibial nerve stimulation with Beurer EM-49 digital neuroestimulator at subtherapeutic doses
|
In the intervention group, Beurer EM-49 digital neurostimulator will be used, with CE marking; and a dose of 80 Hertz (Hz) - 150 microseconds (μs) will be applied. As the control group and the intervention group, the pelvic floor rehabilitator will program the neurostimulator for each case and then they will be trained on how to perform the neurostimulation. In order to apply the therapy, the patient must sit down for the placement of the electrodes. It will be performed on 2 feet at the same time. The first session will be carried out with the rehabilitator to learn how it works and resolve doubts about its use, and later the sessions will be carried out at home. In both groups, a program for carrying out sessions will be indicated according to the following scheme:

Patient global impression of improvement (PGI-I)
Tidsramme: 1 year
|
Assessed by PGI-I questionnaire. The Patient Global Improvement Visual Analogue Scale (PGI-I) will be used to allow patients to comparatively assess their degree of global improvement after undergoing posterior tibial nerve stimulation therapy. The scale in question has only one question that asks the patient to classify the degree of symptom relief obtained with the treatment according to the 7-point Likert scale. The higher the score, the better the perception of quality of life. |
