| アブストラクト | OBJECTIVES: To determine the incidence of cerebral infarction after lobectomy at different sites using inpatient data from a diagnosis procedure combination database. DESIGN: Retrospective cohort study. SETTING: Data were retrieved from the Japanese diagnosis procedure combination inpatient database for patients who underwent lobectomies for lung cancer between April 2018 and March 2020. PARTICIPANTS: The analysis included 37 352 patients from 556 institutions who underwent lobectomies for lung cancer. MAIN OUTCOMES AND MEASURES: The occurrence of cerebral infarction after lobectomy during hospitalisation was estimated using multilevel logistic regression models adjusted for sex, age, body mass index, smoking history, activity of daily living, surgical approach (thoracotomy or video-assisted), clinical cancer stage, comorbidities and hospital-level factors to describe the association between cerebral infarction and different lobectomy sites. RESULTS: Overall cerebral infarction after lobectomy occurred in 99 patients (0.27%): 29 with left upper lobectomy (0.39%), 19 with left lower lobectomy (0.34%), 32 with right upper lobectomy (0.24%), 6 with right middle lobectomy (0.21%) and 13 with right lower lobectomy (0.16%). The multilevel multivariate logistic regression analysis revealed high ORs for the left upper lobectomy and left lower lobectomy groups. In both univariate and multivariate analyses, left upper lobectomy had the highest OR for the occurrence of cerebral infarction compared with lobectomies at other sites. CONCLUSIONS AND RELEVANCE: Left upper lobectomy had the highest OR for the occurrence of cerebral infarction after lung cancer lobectomy during hospitalisation. There is an urgent need to investigate the specific mechanisms underlying postoperative cerebral infarction after left upper lobectomy and to establish preventive measures such as altering surgical methods, using radiological examinations for early detection and better use of anticoagulants. |
