Abstract:

Objective Using the comprehensive complication index（CCI）score to assess the impact of breast reconstruction on complication severity after mastectomy. Methods 227 patients who underwent breast reconstruction after mastectomy from January 2017 to August 2020 in the plastic surgery department of the second affiliated hospital of Soochow university were collected. Data included demographic variables and clinical variables. Results 462 cases（27.3%）had major complications score（CCI ≥ 26.2），and 165 cases had minor complications score（CCI < 26.2）. Autologous valve reconstruction（OR = 4.69，P < 0.001），BMI ≥ 30 kg/m2（OR = 7.87，P < 0.001）， delayed reconstruction（OR = 9.13，P < 0.001）and preoperative radiotherapy（OR = 22.70，P = 0.006）were major risk factors for postoperative complications. In terms of hospitalization time，the CCI ≥ 26.2 group was significantly longer than the CCI < 26.2 group（13.5 vs. 8，P < 0.001）. Conclusions According to CCI score，Autologous valve reconstruction，BMI ≥ 30 kg/m2，delayed reconstruction，preoperative radiotherapy maybe the major postop⁃ erative complications，which are crucial for patients and surgeons when making breast reconstruction decisions.
