Timing of Re-Laparotomy in Blunt Trauma Patients With Damage-Control Laparotomy.

ABSTRACT

INTRODUCTION: Damage-control laparotomy (DCL) was initially designed to treat patients with severe hemorrhage. There are various opinions on when to return to the operating room after DCL and there are no definitive data on the exact timing of re-laparotomy. METHODS: All patients at regional referral trauma center requiring a DCL due to blunt trauma between January 2012 and September 2021 (N = 160) were retrospectively reviewed from patients' electronic medical records. The primary fascial closure rate, lengths of intensive care unit stay and mechanical ventilation, mortality, and complications were compared in patients who underwent re-laparotomy before and after 48 h. RESULTS: One hundred one patients (70 in the ≤48 h group [early] and 31 in the >48 h group [late]) were included. Baseline patient characteristics of age, body mass index, injury severity score, and initial systolic blood pressure and laboratory finding such as hemoglobin, base excess, and lactate were similar between the two groups. Also, there were no differences in reason for DCL and operation time. The time interval from the DCL to the first re-laparotomy was 39 (29-43) h and 59 (55-66) h in the early and late groups, respectively. There were no significant differences in the rate of the primary fascial closure rate (91.4% versus 93.5%, P = 1.00), lengths of stay in the intensive care unit (10 [7-18] versus 12 [8-16], P = 0.553), ventilator days (6 [4-10] versus 7 [5-10], P = 0.173), mortality (20.0% versus 19.4%, P = 0.94), and complications between the two groups. CONCLUSIONS: The timing of re-laparotomy after DCL due to blunt abdominal trauma should be determined in consideration of various factors such as correction of coagulopathy, primary fascial closure, and complications. This study showed there was no significant difference in patient groups who underwent re-laparotomy before and after 48 h after DCL. Considering these results, it is better to determine the timing of re-laparotomy with a focus on physiologic recovery rather than setting a specific time.
