A significant number of patients treated for alcohol use disorder have undergone bariatric surgery.

Bariatric surgery is a treatment for patients suffering from morbid or severe obesity with comorbidities that can be improved by surgery. It is performed by a multidisciplinary team, in collaboration with the treating physician. It is a comprehensive approach, part of a personalized patient plan, and is governed by regulations defined by the HAS (French National Authority for Health). Pre- and post-surgery follow-up are defined within these regulations.

Several studies have been conducted on alcohol use disorder after bariatric surgery, attempting to understand and clarify the mechanisms involved. Alcohol use disorder and bariatric surgery share and are associated with psychiatric disorders.

Therefore, the investigators wish to explore, through the medical records of patients receiving addiction treatment for alcohol use disorder, the consideration of their surgery in their follow-up. This exploration will subsequently allow for improved care for these patients, if necessary.
