    Abstract:
    BACKGROUND: The use of selective nonoperative management for anterior abdominal stab wounds has evolved into a readily accepted practice. Multiple reports have shown this strategy to be both safe and effective. However, there is a paucity of long-term studies. METHODS: A retrospective review was performed of all trauma patients presenting for anterior abdominal stab wounds at a Level I trauma center during a 17-year time period. Primary outcomes were the percentage of patients undergoing an exploratory laparotomy and the negative laparotomy rate. RESULTS: A total of 7,033 patients sustained a stab wound with 1,961 involving the anterior abdomen. The percentage of patients undergoing exploratory laparotomy decreased during the study period from 64.8% to 37.6% (overall 45.8%). The negative laparotomy rate decreased from 21.3% to 8.6% (overall 18.7%). The negative laparotomy rate of patients who underwent exploratory laparotomy immediately did not change over time (13.8%), whereas the negative laparotomy rate of those patients who underwent exploratory laparotomy in a delayed fashion decreased from 25.0% to 6.25%. The overall mortality was 1.9%, with 6.2% mortality for patients undergoing an immediate laparotomy, 0.7% for patients undergoing a delayed laparotomy, and 0.0% for patients managed nonoperatively (p<0.04). The mean length of hospital stay was 6.6 days±0.5 days, with a mean of 9.4 days±0.9 days in patients undergoing an immediate laparotomy, 8.1 days±0.5 days in patients undergo a delayed laparotomy, and 3.8 days±0.2 days in patients managed nonoperatively (p<0.001). CONCLUSIONS: Selective nonoperative management for stab wounds to the anterior abdomen is associated with a decreased operative rate and decreased negative laparotomy rate over time. Selective nonoperative management is both safe and effective for anterior abdominal stab wounds.
