Investigating the trend of revisional bariatric surgery, the complications, and associated risk factors in France.

Abstract

Metabolic and bariatric surgery (MBS) is a highly effective treatment for patients with obesity, with increasing prevalence in France. However, some patients require revisional MBS (RMBS) due to suboptimal initial response, recurrent weight gain, and correction of technique-related complications. Understanding the prevalence and risks associated with RMBS is essential for optimizing patient care. This study aims to assess the rate of RMBS in France and to delineate the associated complications and risk factors. France. Using national discharge data from 2016 to 2022, this observational study compared morbidity and mortality rates between primary and RMBS. Patient demographics, comorbidities, and procedural details were analyzed. Major complications within 90 days post-surgery were assessed using logistic regression models adjusted for potential confounders. Among 284,271 bariatric procedures analyzed, the revision rate was 12.8%. Patients undergoing RMBS were older, predominantly female, and had more comorbidities compared to those undergoing primary procedures. RMBS were associated with significantly higher rates of severe complications (OR 1.58, 95% CI 1.49-1.68, p < 0.001), particularly after gastric bypass (GB) (OR 2.70, 95% CI 2.27-3.20). Subgroup analyses showed increased morbidity following revisional sleeve gastrectomy compared to primary procedures. This study highlights a notable rate of RMBS in France, with evolving trends towards more complex revisions. RMBS are associated with increased morbidity, emphasizing the need for careful patient selection and enhanced postoperative management. Further research into surgical techniques, long-term pharmacological interventions, and surgeon expertise is warranted to optimize outcomes in this population.
