Abstract
AIM: R0 resection of locally advanced or recurrent rectal cancer is the key determinant of outcome. Disease extension high on the sacrum has been considered a contraindication to surgery because of associated morbidity and difficulty in achieving complete pathological resection. Total sacrectomy has a high morbidity with poor function. METHOD: We describe a novel technique of high subcortical sacrectomy (HiSS) to facilitate complete resection of disease extending to the upper sacrum at S1 and S2 to avoid high or total sacrectomy or a nonoperative approach to management. Details of patient demographics, radiology, operative details, postoperative histology, length of hospital stay and complications were entered into a prospectively maintained electronic patient database. All patients had had preoperative chemoradiotherapy. RESULTS: During 2013-2014, five patients, including three with advanced primary cancer and two with recurrent rectal cancer, underwent excision using this approach. All patients had an R0 resection. Four patients had a minor postoperative complication (Clavien-Dindo Grades I and II) and one had a major complication (Clavien-Dindo Grade IIIb). There was no mortality at 90 days, and four patients were disease free at a median of 18 months. CONCLUSION: Patients with locally advanced and recurrent rectal cancer involving the upper sacrum may be rendered suitable for potentially curative radical resection with a modified approach to sacral resection. This pilot series suggests that this novel technique results in a high rate of complete pathological resection with acceptable morbidity in patients for whom the alternatives would have been an incomplete resection, a total sacrectomy or nonoperative management.
