Infectious Complications After Esophagectomy

The retrospective, multicenter study consists of the retrospective and pseudonymous collection of data from the medical reports of patients, covering the period from January 2017 to December 31, 2024, who were treated in each participating intensive care unit. The investigators at each participating center will be responsible for screening and including patients, as well as obtaining their non-opposition. Patients who were hospitalized for esophagectomy will be included, provided there are no exclusion criteria. The following data will be collected after pseudonymization: only the first letter of the patient's last name and the first letter of their first name will be recorded, along with a study-specific coded number, which will differ for each center and indicate the order of inclusion of subjects. A correspondence table will be kept at each center for a period of 15 years. This table will be stored within each participating center. At each participating center, data entry will be coordinated by the investigator responsible for the center. The collected data will be pseudonymized and stored in a secure database located at each participating center. * If the patient is alive: the patient will be informed about the study. Data collection will begin only after the patient has been informed and only if the patient does not express opposition to the use of their data. * If the patient is deceased and the vital status of the patient is known to the investigator: in this case, the investigator will verify in the patient's medical record that the patient has never expressed written opposition to the use of their data for research purposes. If the patient has never objected, their data will be collected.
