Colleen, 41, has endured severe pain since age 14 due to chronic endometriosis that required multiple surgical interventions over her adult life.
She describes waiting approximately seven years for complex gynaecological surgery involving several specialities as a period of suffering.
Such delays have forced some women into hysterectomy, a procedure Colleen avoided through timely treatment.
The Belfast City Hospital has integrated the Da Vinci surgical robot into its gynaecology team since May this year.
This system represents the first of its kind on the island of Ireland and one of only a few operating across the United Kingdom.
Costing £2.4m, the equipment was financed through charitable donations specifically for gynaecological services within the trust.
Four consultants have now been trained to operate the machine, which features multiple towering robotic arms that hover over patients.
The technology is noted for its steadier movement compared to human hands, allowing precise manipulation in tight pelvic spaces.
To date, 130 surgeries have been performed using the system, with 105 specifically involving women with complex endometriosis cases.
Complex gynaecology procedures are now prioritised and are not routinely displaced when other surgical requests arrive.
Colleen was denied a Da Vinci operation earlier this year by just weeks due to case backlogs affecting her urgent treatment.
BBC News Northern Ireland has been granted access to observe the robotic surgery in action at Belfast City Hospital.
