Abdominosacral resection may be the only curative procedure for locally advanced rectal cancer involving the presacral fascia or sacrum. Multimodal therapy might be necessary to prevent local and distant recurrence for such tumors. A 67-year-old man was diagnosed with locally advanced rectal cancer widely involving the right pelvic sidewall and presacral fascia near the S4/5 junction on the right posterolateral side. We performed laparoscopic abdominosacral resection (S4/5) with en bloc right lateral lymph node dissection and seminal vesicle resection to obtain a clear resection margin after systemic chemotherapy with mFOLFOX6 (oxaliplatin, leucovorin, and 5-fluorouracil) plus bevacizumab, followed by preoperative chemoradiotherapy. The total operative time was 660 min, and the estimated blood loss was 550 mL. The final pathological findings revealed no residual cancer cells (pathological complete response). Laparoscopic abdominosacral resection appears to be safe and feasible in selected patients.
