Summary

To investigate the effects of intersphincteric resection (ISR) of ultra-low rectal tumor on the brain-rectoanal function of patients, and to precisely localize the cerebral functional regulatory regions for intervention targets of anorectal remodeling. Utilizing transcranial magnetic stimulation(TMS) technology to explore the functional remodeling of the "new" anorectal muscle groups and provide a theoretical basis for more research on the rehabilitation and mechanism of fecal incontinence.

Conditions

  • Rectal Neoplasms

Interventions

DEVICE

Transcranial magnetic stimulation

The magnetic stimulator equipment is provided by the MagProX100 magnetic stimulator ( MagVenture, Lucernemarken, DK-3520 Farum, Denmark), with 8-shaped coil, a maximum stimulation frequency of 30Hz and a maximum stimulation intensity of 6 Tesla.Stimulation group: Intermittentpulse transcranial magnetic stimulation (iTBS) will be performed with : the cluster consists of 3 pulses, the intra-cluster frequency is 50Hz, the intercluster frequency is 5Hz, the interval is 8.2s for every stimulus. There are 20 cycles and a total of 600 pulses. Each intervention time is 3min11s, and the stimulation intensity is set as 80% resting state motion threshold. The intervention will be performed once a day for 2 weeks.

DEVICE

Sham Transcranial magnetic stimulationt

The magnetic stimulator equipment is provided by the MagProX100 magnetic stimulator ( MagVenture, Lucernemarken, DK-3520 Farum, Denmark), with 8-shaped coil, a maximum stimulation frequency of 30Hz and a maximum stimulation intensity of 6 Tesla. Patients on the Sham stimulation group will be interfered with the stimulation coil perpendicular to the skull, so that they will hear the sound of machine without having therapeutic effects. The parameters will be the same as those in the stimulation group.
