Abstract

Background: Careful selection of patients for the operation plays a major role in long-term results of silastic ring vertical gastroplasty. The objective of the current study is to identify predictive factors for the objective (excess weight loss) and subjective (satisfaction) success of silastic ring vertical gastroplasty (SRVG) for morbid obesity. Methods: Design: Retrospective cohort study. Setting: University hospital. Subjects: 300 patients of 450 who were operated on between 1984 and 1997. Follow-up time was 4.4 ± 2.3 years. Intervention: SRVG. Statistical Methods: Correlations, multi-linear regression model. Results: Average BMI (body mass index) loss: 13.6 ± 7.4 kg/m 2, average excess weight loss was 67.4 ± 33.0%. Satisfaction rate: 81.3%. Correlation was found between objective parameters of successes and the satisfaction of the patient (p < 0.001). Excess weight loss was correlated to younger age (p < 0.005), pre-operative weight and BMI (p < 0.005, p < 0.01, respectively), and shorter follow-up (p < 0.001). Multiple linear regression model revealed that age and preoperative weight were independent variables and correlated to the excess weight loss after SRVG (R2 = 0.303, p < 0.01; R2 = 0.026, p < 0.05). Social support was correlated to satisfaction (p < 0.05). Conclusions: SRVG is an operation with high rates of objective and subjective success rate. Younger and heavier subjects will mostly enjoy SRVG in terms of excess weight loss. Patients who have social support have the most satisfactory emotional outcome.
