Comparison between Laparoscopy-assisted Colectomy and Open Colectomy for Prognosis in Patients with Sigmoid and Rectosigmoid Carcinoma

Purpose: The aim of this study was to compare the oncologic outcomes of laparoscopy-assisted colectomy (LAC) and open colectomy (OC) for colorectal cancer. Subjects: This retrospective, non-randomized study examined 88 patients who were cured with no residual tumors after undergoing a colorectal resection with a D3-dissection between January 1996 and March 2005. The patients were divided into 2 groups, those receiving a LAC (n=43) and those receiving an OC (n=45). The groups were compared with regard to blood loss, duration of surgery, lymph node yield, postoperative hospital stay, complications, recurrence, and survival rates. Results: None of the patients in the LAC group required conversion to OC in this study. Intraoperative blood loss was significantly lower for the LAC group (18mL) than for the OC group (271mL, P
