Feasibility of complete mesocolic excision in elderly patients with colon cancer / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the short-term outcomes and safety of complete mesocolic excision (CME) in elderly patients with colon cancer.</p><p><b>METHODS</b>The clinical pathological factors of 71 patients with colon cancer undergoing CME procedure by the same group of surgeons were analyzed retrospectively from November 2009 to February 2012. The elderly group(≥70 years) and the non-elderly group(<70 years) were compared regarding short-term outcomes and safety.</p><p><b>RESULTS</b>Similar extent of resection could be achieved in the elderly and non-elderly groups in terms of area of mesentery[(13 049±4332) vs. (13 163±4725) mm2, P=0.916], distance between the tumor and the high ligation site[(95±22) vs. (98±20) mm, P=0.516], distance between normal bowel and high ligation site [(130±25) vs. (128±25) mm, P=0.731], the length of colon [(262±60) vs. (245±49) mm, P=0.212], and lymph nodes retrieved(22.0±6.4 vs. 24.8±9.9, P=0.168). The mean operative time, intraoperative blood loss, postoperative complications, time to first flatus, time to first bowel movement, drainage removal time, diet resumption, drainage volume in three days after surgery, and hospital deaths showed no statistical significances(all P>0.05), while hospital stay and expenses of the elderly group were significantly increased(both P<0.01).</p><p><b>CONCLUSION</b>Elderly patients undergoing elective CME operation can achieve similar operative extent and lymph nodes harvest, and the surgical risk is not increased.</p>
