ARTICLE HIGHLIGHTS
Research background
Sleeve gastrectomy (SG) significantly reduces weight and improves obesity-related comorbidities in patients with obesity. However, differences in surgical outcomes between patients with familial aggregation of obesity (FAO) and those with sporadic obesity (SO) have not been elucidated.
Research motivation
To investigate whether FAO influences the surgical outcomes of SG.
Research objectives
To compare preoperative characteristics, postoperative weight loss, resolution of obesity-related comorbidities, and surgical complications between the FAO and SO groups.
Research methods
In this retrospective study, we recruited 193 patients who underwent SG and categorized them into FAO and SO groups based on the presence of obesity in their first-degree relatives. Propensity score matching analysis was used to match the patients at a 1:1 ratio to eliminate confounding factors.
Research results
The baseline data and incidence of obesity-related comorbidities did not significantly differ between FAO patients and SO patients. Two years postsurgery, the FAO group exhibited a lower total weight loss percentage (P < 0.001) and excess weight loss percentage (P < 0.001) than did the SO group. Significant differences were observed between the two groups in terms of remission rates of type 2 diabetes mellitus (T2DM) (P = 0.031), hyperlipidemia (P = 0.012), nonalcoholic fatty liver disease (P = 0.003), and postoperative reflux occurrence rate (P = 0.038).
Research conclusions
Compared to those in the SO group, the FAO patients in the SO group demonstrated slightly weaker medium-term weight loss outcomes; reduced symptoms of T2DM, hyperlipidemia, and nonalcoholic fatty liver disease; and a decreased postoperative reflux rate.
Research perspectives
This study provides a theoretical basis for the treatment, surgical method selection, and postoperative health management of patients with FAO.
