Purpose: Negative laparotomy in patients with abdominal penetrating injuries (APIs) is associated with deleterious outcomes and unnecessary expense; however, the indications for laparotomy in hemodynamically stable patients with ambiguous computed tomography (CT) findings remain unclear. This study aimed to identify the factors associated with negative laparotomy. findings Methods: Data of patients who underwent laparotomy for APIs between 2011 and 2019 were retrospectively reviewed. Patients who presented with definite indications for laparotomy were excluded. The patients were dichotomized into negative and positive laparotomy groups, and the baseline characteristics, laboratory test results, and CT findings were compared between the groups. Results: Of 55 patients with ambiguous CT findings, 38 and 17 patients were assigned to the negative and positive laparotomy groups, respectively. There was no significant difference between the groups with respect to the baseline characteristics or the nature of t he ambiguous CT findings. However, t he laboratory test results showed t hat t here was a difference in the percentage of neutrophils between the groups (negative: 55.6% [range 47.4–66.1%] vs. positive: 79.8% [range 77.6–88.2%], p<0.001), although the total white blood cell count was not significantly different. The mean duration of hospital stay for the negative laparotomy group was 13.1 days, and seven patients (18.4%) experienced complications. Conclusions: Diagnostic factors definitively indicative of laparotomy were not identified, although the percentage of neutrophils might be helpful. However, routine laparotomy in patients with peritoneal injuries could result in instances of negative laparotomy. KCI Citation Count: 0
