[Abdominal surgery: what's new in 2023].

In 2023, robotic surgery has witnessed an expansion in the number of surgical procedures and in the number of platforms on the market. We illustrate the phenomenon, by exploring parietal, œso-gastric and liver robotic surgery. Surgical innovation aligns with advancements in oncology. Immunotherapy now enables "watch and wait" strategies for patients with colorectal cancer, and decreases recurrence rate and improves survival after liver surgery for hepatocellular carcinoma and œso-gastric surgery. The multidisciplinary field of obesity management has seen the development of new medications, diversifying the treatment options, while surgery continues to deliver the best weight-loss outcomes.
