Phenotyping of Patients Seeking Third or Higher-Order Metabolic Bariatric Surgery
摘要
There is a continuous upward trend in the number of repeated metabolic bariatric surgeries (MBS) performed worldwide. In some cases, patients undergo a third or even higher-order MBS, yet there is a paucity of data regarding the clinical profiles of this population. This study aims to characterize the surgical history, anthropometric outcomes, and mental health profiles of patients seeking a third or higher-order MBS.
MethodsBetween 2016 and 2021, candidates for a third or higher-order MBS underwent comprehensive evaluations by a clinical psychologist and a registered dietitian. Sociodemographic, psychological, and health data were collected from medical records, with psychological interviews conducted using a semi-structured DSM-5-based format.
ResultsData was collected from 99 candidates; 84 planned a third MBS, 14 a fourth, and one a fifth. The mean age and BMI were 47.8 years and 41.7 kg/m2, respectively, and 80.8% were women. Most participants (95%) had undergone banding-based procedures as their primary MBS, and about 70% were converted to sleeve gastrectomy as a secondary MBS. Excess weight loss was lower after secondary compared to primary MBS (54.3 ± 47.4% vs. 64.9 ± 35.4%). High rates of psychopathology were observed, including depression (58.8%), anxiety (35.8%), post-traumatic stress disorder (58.5%), and 23.7% reported on psychiatric medication use.
ConclusionsThis study illuminates a distinctive population of candidates seeking a third or higher-order BMS, revealing a notable prevalence of psychopathologies within this group. The findings underscore the importance of conducting further prospective studies to delve into clinical features associated with repeatable BMS.
Key Points• Third or higher-order MBS are increasingly performed worldwide.
• Patients seeking repeated MBS often present with complex surgical histories.
• Weight loss outcomes were less favorable after secondary vs. primary MBS.
• High prevalence of psychopathology was observed in this unique population.
