Early Implementation of Sacral Neuromodulation in Patients With Low Anterior Resection Syndrome.

Early Implementation of Sacral Neuromodulation in Patients With Low Anterior Resection Syndrome: a Randomized, Multicenter, Prospective, Open-label, Pragmatic Study.

A randomized, prospective, multicenter, open-label, pragmatic pilot study of patients with Low Anterior Resection Syndrome treated early (<120 days after discharge following intestinal bypass reconstruction) with sacral nerve root neuromodulation, compared with another group receiving personalized conservative treatment as performed in routine clinical practice.

Beskrivelse

Inclusion Criteria:

  • Adult patients (18 years of age or older) who are capable of signing the appropriate informed consent form.

  • Patients who experience more than 6 episodes of urgency and/or incontinence in the following two weeks after the screening visit, as recorded in a daily bowel diary.
  • Patients with a LARS score >21 points (major or minor LARS).
  • Patients who report at least one symptom and one consequence as defined by the international definition.

Exclusion Criteria:

  • Metastatic disease at the time of surgery.
  • Need for adjuvant chemotherapy at the time of assessment.
  • Active chemotherapy.
  • Patients with an ileostomy.
  • Intellectual or language-related difficulty in answering the questionnaires.
  • Refusal to participate in the study or failure to commit to follow-up visits.
  • Patients with contraindications for sacral neuromodulation implantation (those with pacemakers, active infections, or allergies to prosthetic materials).
  • Patients with active inflammatory bowel disease at the time of surgery.
  • Patients who have undergone other intestinal resections in addition to rectal resection.
