Abstract: Objective To study the risk factors of complications after laparoscopic repair in patients with traumatic liver rupture. Methods 102 patients with traumatic liver rupture in our hospital from April 2017 to October 2020 were collected as the research objects, all patients underwent laparoscopic repair, and the complications were recorded. The Logistic multivariate analysis was used to explore the risk factors of postoperative complications, the exponential equation was established and its application value in judging complications was analyzed. Results There were 38 cases with complications, the incidence rate was 37.25%. Among the 102 patients, there were 14 cases of postoperative infection, 12 cases of postoperative bile leakage, 8 cases of bleeding and 4 cases of liver abscess. The Logistic multivariate analysis showed that the time from injury to admission, blood loss, duration of hypotension and albumin (Alb) level were independent factors, which affected the postoperative complications (P<0.05). The exponential equation was established, which accorded to the results of the Logistic multifactor analysis: Y=0.603X₁+0.654X₂+0.471X₃+0.798X₄+0.899X₅ (X₁=time from injury to admission, X₂=blood loss, X₃=grade of liver rupture, X₄=duration of hypotension, X₅=Alb). Receiver operating characteristic (ROC) analysis showed that the area under curve (AUC) of postoperative complications judged by exponential equation was 0.796 (SE=0.066, 95%CI=0.666-0.926, P<0.001). Conclusion The incidence of complications after laparoscopic repair of traumatic liver rupture is high. The complications are related to the time from injury to admission, blood loss, grade of liver rupture, the duration of hypotension and Alb level.
