Introduction: We previously reported that a multi-component model of autonomic and enteric factors may correlate with ultimate weight loss or gain after restrictive obesity surgery (NGM 2005; 17:472). Patients: We report on 39 patients, 4 male, 35 female, mean age 37.2 years, followed for up to 16 years post-operatively after vertical banded gastroplasty. Methods: Two autonomic measures (adrenergic: PAR and VC and cholinergic: RRI) and one enteric measure (electrogastrogram: EGG) were recorded at baseline as previously described (DDS 44: 74s–78s, 1999). We performed a discriminant function analysis to investigate whether a patient's EGG, PAR, RRI, and VC values could be used to classify that patient as a loser or gainer following weight control surgery. The patients were divided into two categories (10 gainers, 29 losers), depending on the latest weight compared to baseline; discriminant criterion derived from the patient's data was applied to each patient's autonomic and enteric values to determine whether these measurements separated the patients into their true weight category. Results: A discriminate model based on baseline measures successfully predicted ultimate weight gain in 8/10 (80%) of patients who subsequently gained weight and weight loss in 24/29 (83%) of patients who in subsequently lost weight for a total correct classification rate of 32/39 (82%). The same model with data at 3 months post-operatively predicted weight gain in 9 of 10 (90%) of patients and weight loss in 24 of 29 (83%) of patients, for a total correct classification rate of 34/39 pts (87%) (See table). Conclusions: A multi-component model demonstrates that baseline and 3 months post-operative measures can predict ultimate weight outcome from restrictive obesity surgery. [ABSTRACT FROM AUTHOR] |
