摘要

BACKGROUND Pelvic exenteration for locally advanced rectal cancer involving prostate has been performed via open surgery.Robotic pelvic exenteration offers benefits of better pelvic visualisation and dissection for bladder preserving prostatectomy with vesicourethral anastomosis,while achieving clear margins.AIM To determine the feasibility of robotic assisted bladder sparing pelvic exenteration.METHODS We describe robotic assisted pelvic exenteration in three cases of locally advanced rectal cancer involving prostate and seminal vesicles(SV).The da Vinci S robotic system was used.Robotic console was docked at left oblique position for abdominal phase and redocked to between the patient’s legs for pelvic phase.All three cases were performed fully robotically at Tan Tock Seng Hospital by colorectal and urological teams.RESULTS Case 1:67-year-old with low rectal tumour 3 cm from anal verge involving the prostate.He underwent neo-adjuvant chemoradiotherapy and robotic abdominoperineal resection with en-bloc prostatectomy.Case 2:66-year-old with low rectal tumour 3 cm from anal verge involving prostate and bilateral SV.He underwent neo-adjuvant chemoradiotherapy and robot assisted ultra-low anterior resection with coloanal anastomosis and en-bloc prostatectomy.Case 3:57-year-old with metachronous rectal tumour in the rectovesical pouch inseparable from the anterior mid rectum,prostate and bilateral SV.He underwent robot assisted ultra-low anterior resection with en-bloc prostatectomy.Bladder neck margin revealed cauterized tumour cells,and he underwent total cystectomy and ileal conduit creation.Histology revealed no residual tumour.All patients are currently disease free CONCLUSION Robot assisted bladder sparing pelvic exenteration can be safely performed in locally advanced rectal cancer with acceptable surgical outcome while preserving benefits of minimally invasive surgery.
