Interventions

  • Transanal Irrigation System — DEVICE
    Transanal irrigation performed using a CE-marked transanal irrigation system (Irrisedo Flow, Qufora, Allerød, Denmark) for the management of neurogenic bowel dysfunction in patients with Parkinson's disease. Participants randomized to this arm will receive training on device use and will perform irrigation according to clinical practice and individual needs throughout the study period.
  • Standard Bowel Care — OTHER
    Standard bowel care including lifestyle advice (dietary and behavioral recommendations) and the use of laxative agents as clinically indicated. Participants will receive the same frequency of clinical follow-up as the experimental arm.

Study Details

The goal of this study is to learn if transanal irrigation (TAI) works better than standard bowel care (SBC) to treat severe constipation in people with Parkinson's disease (PD). It will also evaluate its effects on gut microbiota and motor disorders, as well as its safety. The main questions it aims to answer are: Does TAI improve constipation more than standard bowel care? Does TAI have an effect on gut microbiota composition? Does TAI influence motor and non-motor symptoms in Parkinson's disease? What side effects or safety issues occur with TAI? Researchers will compare TAI using the Qufora Flow device to standard bowel care (including diet, fluids, and medications) to see which approach is more effective. Participants will: Be randomly assigned to TAI or standard bowel care Perform TAI every other day or follow standard bowel care routines Attend clinic visits at the start, after 6 months, and after 24 months Receive follow-up phone calls after 1 month and 12 months Complete questionnaires on bowel function, quality of life, and Parkinson's symptoms Provide stool samples to analyze gut microbiota Keep a food diary and record treatments

Arms

  • Experimental: Transanal Irrigation (TAI) with Qufora Flow Device
    Participants randomized to this arm will receive transanal irrigation (TAI) using the Qufora Flow device. Subjects will be trained in proper device use after randomization. Treatment is administered as part of routine management of neurogenic bowel dysfunction in Parkinson's disease. Participants will attend scheduled on-site visits at Baseline, 6 months, and 24 months, and will complete telephone follow-ups at 1 month and 12 months.
  • Active Comparator: Standard Bowel Care (SBC)
    Participants randomized to this arm will receive standard bowel care (SBC), including lifestyle advice and recommendations for laxative agents as clinically indicated. Subjects will have the same frequency of contact with the investigator or delegate as the experimental arm, including scheduled on-site visits at Baseline, 6 months, and 24 months, and telephone follow-ups at 1 month and 12 months.
