PTQ Faecal Incontinence Implant

Injectable Soft-tissue Bulking Agent

PTQ is implanted in the Internal Anal Sphincter (IAS) to treat passive faecal incontinence due to a weak or disrupted internal anal sphincter. The procedure is minimally invasive and technically simple (Ref 1). It can be performed under local anaesthesia in an outpatient setting.

Proven Performance

  • Up to 95% of patients show a significant improvement in incontinence scores 2,3
  • Provides sustainable improvement for 12-24 months 2-10
  • Improves patient quality of life 2-4, 7, 11
  • Reinjection is effective 5
  • Helps improve anal asymmetry index which may be linked to increased maximum resting anal canal pressures 2
