Official Title: Evaluating the Effectivenemss of Percutaneous Tibial Nerve Stimulation as a Treatment for Tenesmus in Patients With Pelvic Floor Disorders

Brief Summary:

The main research question is to see if Percutaneous Tibial Nerve Stimulation (PTNS) can improve the symptom of tenesmus in patients with pelvic floor disorders. This includes those who have rectal cancer in situ or who are post-rectal cancer treatment and have Anterior Resection Syndrome.

The secondary research questions are to see if other pelvic floor symptoms and quality of life improves for this patient group and if levels of anxiety and depression improve for these patients.


Detailed Summary:

The aim of the study is to discover if PTNS can be used to reduce the symptoms in those patients with tenesmus due to their pelvic floor disorders. These pelvic floor disorders include rectal cancer in situ, Anterior Resection Syndrome developed after rectal-cancer treatment, or gynaecological problems. Gynaecological problems that can cause tenesmus include radiotherapy for gynaecological cancer, ovarian cysts, pelvic organ prolapse and hysterectomy.

Currently, there is a lack of treatment options available to manage patients with tenesmus and it is hoped that PTNS will provide a simple, non-invasive treatment to this wide patient group with distressing symptoms. Assessment of symptom improvement will be used by analysing the change in scores on the COREFO, e-PAQ and HADS questionnaires, which will be completed pre and post treatment. COREFO is a validated questionnaire which includes questions specifically relating to tenesmus. e-PAQ is a validated questionnaire which looks at all aspects of the pelvic floor (bowel, urinary, vaginal, sexual) along with quality of life. HADS is a validated questionnaire classifying the patient's degree of anxiety and depression as either "normal", "borderline abnormal" or "abnormal".

There have been two pilot studies looking into the effect of PTNS in improving symptoms in Anterior Resection Syndrome patients. However, full papers have not been published of this data. These two studies assessed symptom improvement using questionnaires, but they did not use COREFO, e-PAQ or HADS, or include patients who currently have rectal cancer (i.e. not Anterior Resection Syndrome patients) or gynaecological problems and have the same tenesmus symptoms. Thus this makes this research an original proposal. e-PAQ is widely used in STH to assess pelvic floor symptoms, and thu

Current Primary Outcome: improve the symptom of tenesmus in patients with pelvic floor disorders [ Time Frame: 12 weeks ]

The degree of success of the PTNS treatment will be measured by comparing the results from the COREFO, e-PAQ and HADS questionnaires before and after the 12 weeks of treatment. The treatment will be deemed successful if the post-treatment score is significantly lower than the pre-treatment score.


Original Primary Outcome: Same as current
