Percutaneous Tibial Nerve Stimulation for Patients With Fecal Incontinence

2014-07-23 21:08:16 | BioPortfolio


Percutaneous tibial nerve stimulation is introduced as regular treatment option for fecal urge continence at the Cantonal Hospital St. Gallen. During this introduction phase efficiency und adverse events will be monitored in this observational study.


Before treatment patients will have a proctological exam, a proctoscopy, endosonography and anorectal manometry. Incontinence scores (Wexner, Vaizey, Hanley) and quality of life scores (FIQL, VAS) will be recorded.

Treatment consists of 4 phases with decreasing frequency of percutaneous tibial nerve stimulations (pTNS).

During phase 1 weekly stimulations of 30 mins are applied for 12 weeks. After 6 and 12 weeks incontinence scores are recorded. Additionally after the end of phase 1 quality of life is measured and an anorectal manometry is preformed.

Phase 2 lasts for 8 weeks, with 2-3 stimulations/month Phase 3 lasts for 8 weeks, with stimulations every 3 weeks Phase 4 consists of one stimulation in one month.

After phase 4 incontinence scores und quality of life are measured.

Medical and Biotech [MESH] Definitions

Pain associated with a damaged PUDENDAL NERVE. Clinical features may include positional pain with sitting in the perineal and genital areas, sexual dysfunction and FECAL INCONTINENCE and URINARY INCONTINENCE.

The medial terminal branch of the sciatic nerve. The tibial nerve fibers originate in lumbar and sacral spinal segments (L4 to S2). They supply motor and sensory innervation to parts of the calf and foot.

Disease of the TIBIAL NERVE (also referred to as the posterior tibial nerve). The most commonly associated condition is the TARSAL TUNNEL SYNDROME. However, LEG INJURIES; ISCHEMIA; and inflammatory conditions (e.g., COLLAGEN DISEASES) may also affect the nerve. Clinical features include PARALYSIS of plantar flexion, ankle inversion and toe flexion as well as loss of sensation over the sole of the foot. (From Joynt, Clinical Neurology, 1995, Ch51, p32)

Abnormal descent of a pelvic organ resulting in the protrusion of the organ beyond its normal anatomical confines. Symptoms often include vaginal discomfort, DYSPAREUNIA; URINARY STRESS INCONTINENCE; and FECAL INCONTINENCE.

Disease or damage involving the SCIATIC NERVE, which divides into the PERONEAL NERVE and TIBIAL NERVE (see also PERONEAL NEUROPATHIES and TIBIAL NEUROPATHY). Clinical manifestations may include SCIATICA or pain localized to the hip, PARESIS or PARALYSIS of posterior thigh muscles and muscles innervated by the peroneal and tibial nerves, and sensory loss involving the lateral and posterior thigh, posterior and lateral leg, and sole of the foot. The sciatic nerve may be affected by trauma; ISCHEMIA; COLLAGEN DISEASES; and other conditions. (From Adams et al., Principles of Neurology, 6th ed, p1363)
