title: Safety and feasibility of laparoscopic sigmoid colon and rectal cancer surgery in patients with previous vertical abdominal laparotomy.
abstract: BACKGROUND
  Current study aims to analyze the impact of previous vertical laparotomy on safety and feasibility of laparoscopic sigmoid colon and rectal cancer operations.
  
  
  METHODS
  All consecutive patients who underwent a laparoscopic resection for sigmoid colon or rectal cancer were included. These aspects were abstracted and compared within no laparotomy and previous vertical laparotomy groups: demographics, perioperative aspects, pathological features and survival.
  
  
  RESULTS
  There were 252 patients in no laparotomy group, and 25 cases with previous vertical incisions including lower (n = 12, 48%), upper (n = 7, 28%), and lower&upper (n = 2, 8%) midline and paramedian (n = 4, 16%) laparotomies. Veress insufflation and open technique were used in 19 (76%) and 6 (24%) cases, respectively, during the insertion of the first trocar in previous laparotomy group. Patients in previous laparotomy group were significantly older (59.2 ± 13.4 vs. 66.2 ± 10.1, p = 0.01), but gender, ASA scores, tumor and technique related factors were similar within the groups, including operation time (200 [70-600] vs. 200 [130-390] min, p = 0.353), blood loss (250 [100-1500] vs. 250 [0-2200] ml, p = 0.46), additional trocar insertion (10 [4%] vs. 3 [12%], p = 0.101), conversion (20 [7.9%] vs. 4 [16%], p = 0.25), postoperative complication (59 [23.4%] vs. 4 [16%], p = 0.06) and 30-day mortality (7 [2.8%] vs. 1 [4%], p = 0.536) rates. Oncological outcomes regarding pathological features and 5-year survival rates (65% vs. 73.2%, p = 0.678) were not different.
  
  
  CONCLUSIONS
  The presence of a previous laparotomy does not worsen the outcomes in patients undergoing laparoscopic removal of sigmoid or rectal cancer, thus laparoscopy may be considered to be safe and feasible in these cases.
