Data Sheet 1_Selective non-operative management of traumatic liver injury in Palestine: a retrospective single-center cohort study.docx

Individual components were also reported separately.</p>Results<p>A total of 58 patients were included; 48 (82.8%) underwent initial NOM and 10 (17.2%) underwent initial laparotomy. All 27 penetrating injuries were gunshot wounds. NOM success was observed in 48 of 48 patients (100%; exact 95% CI, 92.6%-100.0%), with no delayed operative conversion or in-hospital death after initial NOM.

An unfavorable NOM course occurred in 6 of 48 patients (12.5%) and was driven by documented endoscopic or drainage procedures in four patients and in-hospital complications in three; component counts overlapped. Higher-grade AAST III-IV injury was associated with an unfavorable NOM course compared with AAST I-II injury (41.7% vs. 2.8%, P = 0.002), as well as greater complication burden, procedure use, ICU stay, hospital stay, and transfusion requirements.

All unfavorable NOM courses occurred after gunshot injury.</p>Conclusion<p>No NOM failure or in-hospital death was observed among the selected patients initially managed non-operatively. However, the small cohort, limited event count, index-hospitalization follow-up, and absence of consistently recorded physiologic selection variables preclude definitive conclusions regarding safety or comparative effectiveness. Higher-grade AAST III-IV and gunshot injuries were associated with more complicated in-hospital NOM courses and greater resource use.</p>
