The Role of Diagnostic Laparoscopy in the Evaluation of Abdominal Trauma Patients: A Trauma Quality Improvement Program Study.

PURPOSE: We aimed to identify factors related to delayed intervention in abdominal trauma patients who underwent diagnostic laparoscopy using a nationwide databank.

METHODS

From 2017 to 2019, abdominal trauma patients who underwent diagnostic laparoscopy were retrospectively evaluated using the Trauma Quality Improvement Program. Patients who underwent delayed interventions after a primary diagnostic laparoscopy were compared with those who did not. Factors associated with poor outcomes that are usually correlated with overlooked injuries and delayed interventions were also analyzed.

RESULTS

Of the 5221 studied patients, 4682 (89.7%) underwent inspection without any intervention. Only 48 (0.9%) patients underwent delayed interventions after primary laparoscopy. Compared with patients receiving immediate interventions during primary diagnostic laparoscopy, patients receiving delayed interventions were more likely to have small intestine injuries (58.3% vs. 28.3%, p < 0.001). Among patients with hollow viscus injuries, a significantly higher probability of overlooked injuries that required delayed intervention was observed in patients with small intestine injuries (small intestine injury: 16.8%; gastric injury: 2.5%; large intestine injury: 5.2%). However, delayed small intestine repair did not significantly affect the risk of surgical site infection (SSI) (p = 0.249), acute kidney injury (AKI) (p = 0.998), or hospital length of stay (LOS) (p = 0.053). In contrast, significantly positive relationships between delayed large intestine repair and poor outcomes were observed (SSI, odds ratio = 19.544, p = 0.021; AKI, odds ratio = 27.368, p < 0.001; LOS, β = 13.541, p < 0.001).

CONCLUSIONS

Most examinations and interventions (near 90%) were successful during primary laparoscopy for abdominal trauma patients. Small intestine injuries were easily overlooked. Delayed small intestine repair-related poor outcomes were not observed.
