Abstract:
Total pelvic exenteration (TPE) may be the only procedure that can cure T4 rectal cancer that directly invades the urinary bladder or prostate. Here, we describe our experience of laparoscopic TPE with en bloc lateral lymph node dissection for advanced primary rectal cancer. A 62-year-old man diagnosed with advanced lower rectal cancer (T4bN0M0) underwent laparoscopic TPE with en bloc lateral lymph node dissection after neoadjuvant chemoradiotherapy. Ligation of the dorsal vein complex was performed under direct visualization through the perineal approach, and the large perineal defect was reconstructed using bilateral V-Y advancement of the gluteus maximus musculocutaneous flaps. The ileal conduit was constructed extracorporeally through an extended umbilical port that was extended to 4 cm. The total operative time was 831 min and estimated blood loss was 600 mL. Laparoscopic TPE appears to be safe and feasible in selected patients.
