Laparoscopy versus conventional laparotomy in the management of abdominal trauma: a multi-institutional matched-pair study

Laparoscopy is being increasingly applied as either a diagnostic or therapeutic intervention in the management of abdominal trauma. However, its outcomes in comparison with conventional laparotomy remain unclear, especially in terms of therapeutic management.

This retrospective cohort study included patients from three trauma centers in Beijing, China. Fifty-four patients undergoing laparoscopic interventions for abdominal trauma by experienced laparoscopists were enrolled in the laparoscopy group (LP group). Another 54 patients who underwent laparotomy (LT group) were matched according to the patients’ baseline characteristics, causes of injury, and hemodynamic parameters. Perioperative clinical parameters and short-term survival were compared between these two groups.

The baseline characteristics were comparable between these two groups (LP vs. LT: Age, p = 0.112; Sex, p = 0.820; Injury severity score, p = 0.158; Cause distribution, p = 0.840). The most common cause was traffic accident (36.1%) and the most frequent surgical intervention was bowel repair/resection (34.3%) in our study. The operation time was similar in these two groups (LP vs. LT: 202.2 ± 72.58 vs. 194.11 ± 82.95 min, p = 0.295) while post-operative complication rate was slightly reduced in LP group (7.7% vs. 13.5%) with no statistical significance (p = 0.383). Opioid use was lower in the LP than LT group (11.67 ± 4.08 vs. 26.0 ± 13.42 morphine equivalents (MEQ), p = 0.034). The hospital stay was significantly shorter in the LP group (13.48 ± 10.9 vs. 18.64 ± 14.73 days, p = 0.021). One patient in the LT group died of an intra-abdominal abscess and multiple organ dysfunction syndrome 19 days postoperatively, while all patients in the LP group recovered and were discharged.

Laparoscopy is feasible and safe in treating abdominal trauma patients in hemodynamically stable conditions performed by experienced surgeons. Laparoscopy might have the advantages of reduced pain and quicker recovery with similarly favorable clinical outcomes.
