Surgical Outcomes of Laparoscopic and Open D3 Dissection for Clinical Stage II/III Descending Colon Cancer.

Abstract

To compare the surgical outcomes of laparoscopic colectomy (LAC) with Japanese D3 dissection for descending colon cancer (DCC) with those of open colectomy (OC). Seventy-two patients who underwent OC or LAC with D3 dissection for clinical stage II/III DCC between September 2002 and June 2019 were evaluated in terms of short-term outcomes. The long-term outcomes of the 59 patients who underwent surgery between September 2002 and June 2016 were evaluated. Twenty-six patients underwent OC and 46 patients underwent LAC. The blood loss was significantly less in the LAC group. The complication rate was similar in both groups. The rates of 5-year overall survival (95.8% in the OC group vs. 89.9% in the LAC group) and relapse-free survival (79.2% in the OC group vs. 82.1% in the LAC group) were similar in both groups. LAC is an acceptable treatment option for stage II/III DCC.
