title: Curative colectomy via minilaparotomy approach without utilizing specific instruments.
abstract: BACKGROUND
  This study evaluated the need for specific instruments when performing a curative resection of colon cancer via a minilaparotomy approach, which has been reported to be a minimally invasive alternative to a laparoscopic approach.
  
  
  METHODS
  The feasibility, safety, and early oncological outcome were compared among 73 patients (first group), in whom a curative resection of colon cancer was performed via a minilaparotomy (skin incision < or =7 cm) utilizing specific instruments (North-bridge retractor system) between September 2002 and March 2005, and 94 patients (second group), in whom a similar procedure was performed without utilizing specific instruments between April 2005 and October 2007.
  
  
  RESULTS
  The two groups did not differ significantly in terms of age, sex, body mass index, site of tumor, level of lymph node dissection, blood loss, UICC stage, number of harvested lymph nodes, incidence of postoperative complications, length of postoperative hospital days, or overall survival, although the frequency of prior abdominal surgery was higher (38.3 vs. 21.9%; P = 0.03) and the median operating time required for a standard lymph node dissection was shorter (120 vs. 135 min; P = 0.03) in the second group.
  
  
  CONCLUSIONS
  With improved techniques and experience, specific instruments are not necessary for the performance of a curative colectomy via a minilaparotomy approach.
