Short-term efficacy of laparoscopic-assisted right hemicolectomy with D3 lymph node dissection in colon cancer / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the feasibility and short-term efficacy of laparoscopic-assisted D3 lymph node dissection for right colon cancer with a medial-to-lateral approach.</p><p><b>METHODS</b>Clinical data of 61 patients with right colon cancer undergoing D3 lymph node dissection from March 2006 to June 2010 were analyzed retrospectively. Among them,29 underwent laparoscopic-assisted right hemicolectomy (LARH group) and 32 underwent open right hemicolectomy (ORH group). The number of lymph node harvest, operative details, and complication rate were compared between the two groups.</p><p><b>RESULTS</b>The mean number of lymph node harvest did not differ significantly between the two groups (16.9±3.8 vs. 15.4±3.6). As compared to ORH group, although the operative time was significantly longer [(214.4±37.9) min vs. (193.3±28.8) min] in LARH group, the mean blood loss [(83.4±38.0) ml vs. (192.7±43.6) ml], time to first flatus [(44.6±20.8) h vs. (70.4±80.0) h], time to resumption of soft diet[(32.5±10.6) h vs. (59.7±10.4) h], and postoperative hospital stay [(11.2±2.2) d vs. (13.8±2.8) d] were more favorable(all P<0.05). Complication rate was lower in LARH group(10.4% vs. 9.4%), however the difference was not statistically significant.</p><p><b>CONCLUSIONS</b>LARH with D3 lymph node dissection is oncologically comparable with ORH for right colon cancer. It is a safe and feasible procedure associated with rapid postoperative recovery.</p>
