Analysis of influencing factors of unplanned reoperation in patients with oral cancer
Objective To investigate the related influencing factors of unplanned reoperation (UR) in patients with oral cancer.Methods A total of 160 oral cancer patients with UR who were hospitalized in the Department of Head and Neck Oncology,West China Hospital of Stomatology,Sichuan University from Janu-ary 1,2018 to December 31,2022 were selected as the study group,and another 160 patients without UR in the same period were selected as the matching group by 1:1 matching.The clinical data of the two groups were compared.The variables that met the requirements were screened.The multivariate logistic stepwise regres-sion model was further used to analyze the influencing factors of UR in oral cancer.Results UR mostly oc-curred within one day after surgery in patients with oral cancer (66.88%),mainly due to flap vascular crisis (48.13%).Compared with the matched group,the hospitalization time of the study group was prolonged,the hospitalization cost was increased,and the differences were statistically significant (P<0.05).Multivariate lo-gistic stepwise regression analysis showed that albumin and neutrophil-lymphocyte-ratio score (ANS,OR=1.693,95%CI:1.207-2.347,P=0.002),difference in hemoglobin levels before and after surgery (OR=1.056,95%CI:1.035-1.077,P<0.001) and free tissue flap repair (OR=4.609,95%CI:2.350-9.036,P<0.001) were the influencing factors for UR in patients with oral cancer.Conclusion UR prolongs the hospi-talization time and increases the hospitalization cost of patients.High ANS,large difference in hemoglobin lev-els before and after surgery,and free tissue flap repair are independent risk factors for UR in patients with oral cancer.
